About This Class

Use your old computer components to mine for crypto.

This class shows you how to build a crypto-miner that works on the blockchain.  That miner can earn crypto-coins if done right.  Some crypto-coins are worthless, some are worthwhile.

Maintaining the cryptocurrency blockchain (also called mining) takes knowledge, construction, programming, work, and maintenance of your rigs.

It's all within your ability to do, though.  If you can plug in a lamp, you can build a crypto miner.

You probably have an old computer that has parts you could use to mine cryptocurrency.  

This class shows you how to recycle old computer gear into a working cryptocurrency miner; a very important integral part of the new blockchain technology, which allows for rewards based upon the performance of your miner.

In this class you will discover:

  • The free software you need

  • The free online services you need

  • The list of computer parts you need (all of which you may already have, or can scavenge)

  • How to build your mining rig even if you've never built a computer (can you plug in a lamp?)

  • How to tie the software, services, everything together

  • How to mine cryptocurrency

1. INTRO - Crypto Mining with Used Gear: Hey, welcome. I'm glad to have you here. I love skill share. I guess you'd low-skill share too or you wouldn't be here. I also love cryptocurrency, and I love mining for cryptocurrency. And I'm going to show you how to mine for cryptocurrency. I'll explain it to the granular detail. There's nothing that will be left out. I want you in the mining community and there's a lot of cryptocurrency to be had out there. As we go along, I'm going to be referencing some things like the exchange, the mining manager, the mining pool, also the USB burner and software Wallet. My personal website is Dan Harvey, So that's where the links are so that you can go there and sign up for these things. Because to successfully mine cryptocurrency, you have to have all of these things in place. Hey, look, I just want to make absolutely clear that you understand there are a lot of people on skill share who teach you how to price crypto currency and buy cryptocurrency and trade cryptocurrency and my do futures and all that stuff that they do like with stocks and bonds and financial advice. That's not me. I'm not here to offer financial advice. I'm just a guy who likes to mine and I can show you how to mine cryptocurrency. And there's a wide range of crypto currency out there. Some of it is worthless. Some of it's worth a lot. Okay. I'm going to show you how to use probably the gear that you already have. If you have a cell phone, like an old smartphone that's two or three generations old. You can use those if they're new junk drawer somewhere, pull them out, we can use those. You get some old tablets, some old laptops maybe are old and desktops, the best thing is if you've upgrade, like if you're a gamer and you've upgraded your gaming system, those little gaming cards are excellent miners and it's entirely possible that you got the stuff laying around your house for free to do this mining. That's the goal. The miner that we do in this course, I built out of a couple of old gamers that I acquired from friends. It's not nearly as hard as you might think, but it is precise. It is a detail oriented thing to make it work. I'm here to give you those details unexcited. You're with me. Let's get started. 2. Class Project: For the class project, I want you to keep track of the dollar amount and the time amount that it takes you to put together this this rig. Alright? And then I want you to put the group together and take a picture of it and post that in the, in the area of the class projects area so we can see that happen. Okay? That's the class project is keeping track of what you're doing, building it, taking a picture of it, and then posting it. Right? We're going to focus on. 3. How Crypto Mining Works: So what is crypto mining? That's really an excellent question and that's why you're here. You go out in your yard, some mountains somewhere. You start digging your Mining and you pull out ores are minerals or Jim stones or whatever that's mining, you actually do work to get something that has value, that has a limited supply. That's why very much why gold is valuable. It has use, it seen as a store of wealth. It's unlimited supply and high demand. You can do everything that gold and silver and copper does, with the exception of being components and stereo systems or electronics and making jewelry, cryptocurrency does better. It's a great store of wealth. It's really transportable stuff. I want to transport a million dollars. Well, if it's a million dollars worth of silver, holy smokes, how much is that at? I don't know. Whatever the price is per ounce. Right. But if I want to try, if I want to transport a million dollars in my electronic wallet. That's my electronic wallet right there. Right? Nothing to it to my pot. That can be $1. It can be nothing. It can be a million dollars or ten zillion quadrillion dollars. Sounds like the national debt. If you go down to Fred circles Carla, and buy a car for $5 thousand, thread takes your credit card and he puts it in his machine, and what happens? Well, the credit card company is now alerted that you are trying to buy a car from Fred. That computer that is owned by the credit card company, looks at the amount of the item you want to buy. So five grand and it says Hold on just a second. So then the credit card company computer goes to your bank and says, is $5 thousand in this account? Bank's computer answers yes. So the bank's computer talks to the credit card companies computer that credit card companies computer then goes and talks to Fred's computer is yes, there's $5 thousand there. Go ahead and give him the car and let us know when the transaction is done. Meanwhile, the computer goes back and says, okay, friends doing this. So let's put $5 thousand and momentary escrow so that the $5 thousand a secure so you can't buy a car, then quickly go buy another car. Your bank then puts it in a lockdown in escrow, and then your bank tells us the credit card company, okay, it's an escrow. So then Fred gets a notice from the credit card company. Okay. The money's in escrow go-ahead and giving the car. So then you've got the car, the money has now moved from your bank account into Fred's BankAccount? Yes. Now, all that has happened with three computers talking to each other. That's all that happened, was code transferred back and forth. Fred did not have a guy from the bank come over and given $5 thousand, the credit card company didn't go over and look to see if you actually had $5 thousand in your account. They did it all digitally. So for that, the credit card company will take a percentage. Sometimes it's as low as like 3.5%, but usually it's six ish percent. Same thing if you go to the grocery store, you get a $100 worth of groceries. You get a $100 worth of groceries. Your bank gets charged a $100. But the grocery store only ends up with 90, $94 because the credit card company in the middle that did all the math keeps the $6. So now let's go to cryptocurrency to make that same transaction. We still have the same players. We still have Fred's Merkel or the grocery store. We still have your bank. Now what happens is, instead of there being one entity in the middle of the credit card company. Now, what we have are people like you and people like me who have a bunch of little crypto machines somewhere, bunch little crypto miners doing all that math that the credit card company used to do. And instead of charging 3.5 to 6% for the transaction, we're only charging between a 100th of a percent and maybe 1%, maybe 2%, depends on the coin you use. Each coin is going to charge for. It's called gas. That's the fee that gets paid to the miners who do the actual transactions. Now what happens is there are not just my little computers out in my my barn and in my garage and maybe one of the bedroom, each miner, each computer is not doing the entire transaction. What happens is there are tens of thousands of computers spread all over the internet and we're all doing one-ten thousandth of this transaction. That transaction fee or that gas, is now divided amongst all the people who participated in the process of verifying that money and then moving that money or that currency. And it happens proportionately to how many minors you had involved in that process. If I had 50 and you had ten or if I had one, you had 75, you're going to get 75 times more of that gas than I am or I'll get five times more than you did. So your little minor that we're going to build out there working and what it's doing is it's not just burning up electricity. It's not just heat in your house, which it certainly will if you get enough of them or causing a little bit of noise, what it's doing is it's doing math equations. It's computing transactions that are happening on the web of currency moving around from this place to that place, to this place to this place. But it doesn't so much more effectively. And for so much cheaper than credit companies and banks do, that, there's a market for it. And now's the time for you to jump in and get your share. 4. Why You Need an Exchange: Alright, let's talk about exchanges. What is an exchange? There are lots of exchanges. Some are based in the United States, summer based in New Zealand, summer based in China. In fact, I think just about maybe with the exception of Africa, I don't think they have an exchange, but they're all over the world. They Africom am an exchange. An exchange is a place where you can take your cryptocurrency or your fee money, which is dollars and the United States and Canada, pesos in Mexico bought if you're from Thailand, Yen from Japan, all that stuff. You can take that fiat currency or your credit card or cryptocurrency and you can go to the exchange and you can exchange what you have for what you want. Very cool. Now, there's an exchange that I use. And it's going to be the one that I illustrate during this class for you to get cryptocurrency into your bank account or to get, to turn a cryptocurrency into cold hard cash, you have to have an exchange. So what happens is if you want to sell, say you've been mining, okay, you've been crypto mining and you've got I don't know. I'm going to speak in dollars because I think in dollars. Okay. So let's say you've been mining and you now have $50 worth of cryptocurrency. Well, let's say a theory M, Okay? So you've got $50 or theorem, but you know what? My wife needs some new shoes and $50, I'll just cover it. So what I'm gonna do is I'm gonna take my $50 worth of a theorem. I'm going to send it to the exchange and I'll show you how to do that. We're going to send it to the exchange. You can change it into US dollars. Or you can, meaning you can sell your theorem for US dollars. And then you will have, you will have on your account, it will show that you had $50 worth of Ethereum and $0 and then you make that transaction and then book, they swapped places. Now you have $50 and then you can go to the thing and say sinned. The, the, the, the button that says what do you want to send and where do you want to send it? I want to send my US Dollars and I want to send them to this bank account. And then in a couple of three days or whatever it takes for the transaction to happen, the money shows up in your account. This is real. You mind cryptocurrency. You sold it for your fiat funds. You sent those PHI up funds to your bank. Now you can hop in your car, go to the store, run your card, or go to the bank and get your cash and go to the store and buy, buy your baby those new shoes. 5. Setting Up Your Exchange: Some coins or mineable, some coins are not mineable. Bitcoin is in fact mineable, but you have to have an async rig. And those are really expensive and beyond the purview of this class. So at the moment, a theorem is the coin, at least my coin of choice to mine, sometimes a theorem is not the number one coin. There are other coins that are sometimes better, that produced better results per my parameters of what I want to have happen, what I want to mine, the cards I'm using. So what we will be doing in the course of this, in the course of this course is mining a theorem. Now, as you might imagine, I already am a member of this exchange and so I really can't go any further than this. You can, you know, it you'd put your name in here in your email, the email that you're going to be consistent with. This. This is the email that you're using for all of your cryptocurrency activities. And then choose a good password and tell them where you are and certify the ER 18. And at some point because of a thing called K, Y, c, That means know your customer. Homeland security in the United States enacted does some laws or some policies now to where you can't just get on an exchange without the exchange in the US knowing where you are. And this exchange is based in the United States, so they comply with that. And if you live in the United States, you are compelled to comply with that as well. Now, some people will use VPNs and stuff and, and get around that and join other exchanges around the world. But that might be frowned upon by your local government. I don't know that I would encourage that. You're going to want to join you. They're going to, they're going to ask you for your ID. You may have to send them a photograph of your driver's license, your voter registration card, maybe something like that. They're going to want banking information. That's your routing number and your account number so that there's, I mean, if you're going to sell your cryptocurrency to them and you want cash, they have to they have to have some place to which they can transfer that cash. That makes sense. And because of the homeland security rules, they want to know who you are. So the bank knows who they're dealing with, insulin that the government knows who they're dealing with. And so the IRS can keep track on if you're paying your taxes or not, and I always encourage you to pay your taxes, do that, that will save you a lot of hassle and nobody got time for that. As they say. Let me throw in just a quick note here. The baking system. You know, your standard traditional, We are the bank. We own your money. You don't own your money. You're lucky we let you use it at all. Those guys, they're kind of unhappy with cryptocurrency because they realize that the world may be changing and they don't have as big a stake in it or control over you, maybe as they used to. So a lot of times what happens if you are using an exchange and you send your money directly to your bank account, which you do indeed need to put in here as, you know, as the final stop of your money. Let me encourage you to also put in PayPal or some other form of what's considered legitimate. A legitimate stop because you can send your money from your crypto currency exchange to PayPal and then from PayPal to your bank. And there is no problem. But a lot of times the banks get persnickety and they say, wait a minute, what are you, what are you doing with cryptocurrency and sending money to us from a crypto currency exchange. We think you're scanning or we think that's a scam, or we don't recognize your, you know, your sovereign right to life, liberty and the pursuit of happiness. And that includes, you know, your financial situation. So Lincoln, your PayPal. And whenever you change a crypto currency into your fiat currency, then sin that fiat currency to your PayPal and then send that to the bank. If the bank gives you any grief. The first three or four times I sent money to my bank. They they they locked my accounts. Then I went and talked to them and they don't do it so much anymore. In fact, they haven't done it in a year or two, but they did it all the time at the beginning. So you're going to have to fill this out on your own. And then as we continue on, I I will be inside of my account and you will be inside of your account and you can work with me as we go through it. 6. Convert Your Crypto Into Other Crypto. : So let's do some stuff. First thing. Let's see, you can see I've got $448.47 in here. I've had a I've had a boatload more and I've had a whole lot less. So at the moment I'm go to portfolio and see what I've got in here right now. I've got $225 of band protocol. I've got $223 of a theorem. I've got to twenty-four cents worth of Al grand for since we're the bitcoin cash and $0.02 worth of Bitcoin SV. That's what I've got. So let's move some, let's move some stuff around lists by islet cell. Let some experience with this exchange can do. First thing I'm gonna do is I'm gonna come up here, hit buy and sell. And you see it says biases cell, it says convert. I'm going to convert. And it says from what to what? Well, I have a bunch of band and I want to convert that to, let's, let's pick something. I kinda like still are lumens. Let's do that. I want I want to buy twenty-five dollars worth of I want to convert not by I want to convert twenty-five dollars of band to twenty-five dollars worth of stellar. So I'm going to, I'm going to preview that now. And what I'm gonna get is I'm going to get 87 stellar lumens for twenty-five dollars worth of band. You know, what I think I'm gonna do is I'm going to X out of that and I'm going to, I'm going to get, I want to, I want a 100 stellar lumens. So let's go back. I'm a say $30 worth. Okay, that's good enough. And then I'm going to say convert now. And it went through someone of you, my transaction converted from band protocol. There it is. Okay. Cost me a little bit of money to do that. So let's go back to the portfolio and let C has had my yeah, my stiller lumens have shown up already. So there they are. I had $29.33 of stellar lumens. That's a 104 stellar lumens and I have slightly less band protocol now. I'm gonna do now is I want to sell some band. And what I want is I want it deposited into us cash, right? So let's do, let's try 40 bucks. I want to sell $40 worth of band protocol because I'm gonna send this us cash to my bank account. So we're gonna preview the sale. That's that's fine. It's gonna it's gonna cost me a $1.90-nine to sin that $40. So what I'll get a total payout of is $38.01. Now these don't all convert instantly. Sometimes they do. But you see right there, I still have US dollar or USD C, which is the USD coin, which is tied to the dollar. So one coin equals one US dollar. I'm in value and as the dollar fluctuates, so as soon as that coin, it's a stable coin. At some point after all of the transactions are done in and things work around and the computers all figure it all out. And my money will show up here and I'll keep an eye on it. It'll show up at some point, but then I'll have 38 actual dollars that I can then send to my bank. Oh, there it is. $38.08. Let's try that. So now what I'm gonna do is my, my $38.01 showed up. So I'm going to click on this because I want to send this to my bank. I want to send this home. So I clicked on it and now it says, do you want to withdraw our deposit? I could go here and hit deposit. And there you are. That's my, that's my bank. And I could put in a dollar amount here and I'll say a 100 bucks or whatever. And I could, I could buy a $100, sent a $100 to my exchange here, and then I could use that to buy more coins, but that's not what I'm doing. I don't want to do a bank deposit. I don't want to do a wire transfer, but I want to do is I want to withdraw and I'm going to hit withdraw all and I'm going to hit Continue. And where do I want to go? I want to go right there to my bank account. Hit continue and withdrawn out. And I'm done. And in some time and I'm not early exactly. I think I've taken a day or two before. It moves fairly quickly. I'll have my $38.01 show up in my bank account. And then I can give that to my wife and she can go spend it. It's very cool. Alright, what else can we do here? Let's go back to the portfolio. We did, we did some exchange, we did some converting right from 1 to another. We sold some. So that we were able to turn that into US dollars because we self-select for US dollar. Otherwise we would have converted it if we're going to another crypto coin. So let's bicyclists. Heck, why not less by some, don't want to buy Bitcoin. Don't want to buy. What do I want to buy? What do I not have any of? Like chain link. And I like Z cash. And I like dash. Dash and z cash kind of have a little bit of a rep because they are totally untraceable. So a lot of ne'er-do-wells and shadowy figures use those. By some chain link. Day 50 bucks. So preview the by. By now. It's gonna, it's gonna total cost me 50 bucks. The bank's going to charge me a buck 99. So was that, that's 4%, which is not much, not much different than using an ATM. I guess. I guess that's not shown up yet. So it will not to worry as long as you pay attention. And I've said this before, I think I'm gonna say it again. I'm going to say it now. Make sure that when you are moving money from one account to another, or from one account to a wallet or an exchange to your wallet, or from your wallet to somebody else that you are sending. Your Ethereum 2ND Ethereum wallet. Make sure you are sending bitcoin to a Bitcoin wallet, light coin to a light coin wallet. Because you're going to end up losing it. If you send any coin to another coin wallet, you will lose it. Like something like Uda swap, which is it in here? Yeah, Yunus swap. If I send you to swap to my wallet, it shows up in my Ethereum account as a subset because a lot of these coins are built on top of the platform for other coins. But generally, make sure. And that's why I really like the the nano ledger X Hardware wallet because it really idiot proof stuff. You have to really try hard to lose your money using the nano ledger X Hardware wallet because it makes you check every step of the way and it makes you confirm that you've looked at something. And it does a great job of comparing everything and saying, you know, you're about to make, you're about to do something really stupid idiot, or that's not actually the words that it uses. It doesn't actually speak to you, but it gets the message across. So let's see, we did some bind, we did some selling and did some converting. We did not do any sending yet. 7. How to Send & Receive Your Crypto: And we did not do any receiving yet. So let's do that. First thing I want to do is I want to, what have I got? I've got I've got some Ethereum. Yea. So what I'm gonna do is I'm going to send it to my Ethereum wallet. Give me just a second to send it to a wallet. I have to know that wallets address. So I'm going to go get my a theorem wallets address. So let's do that. So here I am at my wallet and I'm gonna type in my password. So what I wanna do is I want to receive into this wallet, right? I don't want to receive into this wallet. So I'm going to hit receive. And here is a number that you seen before. This is my a theorem wallet. And so I'm going to copy that number. So let's lets say Yes, that was right. So first done on here, there is no done on oh, there it is. X. Ok. So at the moment I have how much 98 bucks in here? 98 bucks. Now let's go back to the exchange. So now what we're gonna do is we're gonna say sinned. So we want to send, well, what do we want to send? We want to send, Well, it's absolutely right. A theorem. Okay, how much do I want to send? I wanna send 50 bucks. Let's do this. I don't want, I want to send $5,555. Now, I'm going to paste my address wallet right here. Okay. And I can write a note. How about you buy us some Thai food? Okay? That's totally optional. You don't have to put a note in there. So I've got the address, the address to which I want to send this money, right? When we were at the address, when we're the wallet, I grabbed my receive address. Now we're on this site because I'm sending from this site to the other site. The other site is going to receive, the wall is going to receive and it's going to receive it at that address. So now I'm going to hit continue. And I'm going to hit sin. Now. You will need to confirm your sinned. They called TFA. It's an extra layer of protection that you get things right. And this number changes by the minute. And they will send you if you're not on Google Authenticator, which I am. They will send you via text, an authentication number that you're supposed to put in here just to, just to make sure that you are who you say you are, and you own the phone that you say you own something, hit Confirm. And it should be done. It is. So now let's jump out here and we'll go back to my wallet. And I'm still at 98 bucks. So this'll take could take ten minutes. I've had to take as long as 20 minutes. I've had it take as few as almost instantly well, and in fact, as I'm talking, it just showed up. So there we are. So and that was that was all in real time. So no edits at all if you'll check that out. So what was that? 121425 seconds. Very nice. So we received it. And I can do the same thing here. I can send from here and I can send it to another address it with asked me for the address, I can send it right back. But I wanted to to the exchange, which I don't want to do because all I'm doing is just I'm just paying for gas going in each direction. So I'm going to leave this here, go back, let's go back to the exchange. So now you've done it. We've, we've, we've bought, we've sold, we've converted. We've sent and we have well, we haven't received here, but I would do the same thing. This would be my receiving address into this account on my exchange wall. Now one cool thing about this exchange I really, really like is over here it gives you a chance to earn rewards. And these are not bad. You'll earn like three bucks in Comp coin for just watching this video. Earn three bucks and calm coin for watching this. And just like that and that keeps going. You can see I've already earned nine bucks here and I think I've earned more. Anyway. There's quite a bit you can do here plus a few if you stake. Or as you keep this some coins, they will show up here and give you lifetime rewards just for holding onto those as called staking this coin, Taizong pays 4.63% and cosmos pays five. Die paste to I like Al Gore and I don't see how grand on here. But if you, if you were to buy algorithms, algorithms actually pays 6%. So, but our Grand also pays 6%. If you're keeping it in your wallet, you just have to send it only update the amount when you send or receive. So it doesn't compound the interest unless you've done a transaction. So some people just send themselves $0 in alga round and it will update the system. So there you go. That's a little inside tip. But that's how the exchange works. You now, let's go back to portfolio here. All the other cool thing here is prices. You can see that at the moment, bitcoin is worth $36 thousand per coin. A theorem is worth 1100 a coin 1166 x RP is at $0.28 and so forth and so on. The, the world is your oyster, my friend, jump right in. Today market's down 4.6%. You'll get to where you're immune to this down 4.610.5, whatever, because you don't want it to swing your moods, their days you come in and everything is rosy and all these numbers are green like this one's green chain links up 18%. Today. Glad I bought some chain link. I'd like her to keep going up and I suspect it might. Again, I am not your financial advisor. I've lost money and I've made money and cryptocurrency. But the mining is consistent for me. And I hope it's consistent for you. And it's a whole lot of fun. 8. Why You Need a Crypto-wallet: Let's talk about wallets. You've got money in. Cryptocurrency isn't money. And you need to keep your money in a wallet. And that makes sense. You don't want to, you don't want it floating around where anybody can get a hold of it. The way you control your money is through having a wallet. Now there are many types of wallets. There are, well, in one sense, having your money on an exchange is having your money in a wallet. The exchange has a wallet that is for you. When you deposit your money, it goes just into your wallet. That's not a really safe way to keep it. I wouldn't keep my money on an exchange for very long. I would put it there, maybe do the business I had with it, changing it, exchanging it, buying more cryptocurrency, selling cryptocurrency, getting fiat cash, sending at home, whatever I'm doing. And then I would move all my money after I had done my business on the exchange, I would move my money back into my wall. Now there are several types of wallets is called going into cold storage when you take your money in a place that's on the internet, which in exchanges on the internet, okay. Also you can leave your money and you're mining pool. That's all. That's on the internet. That's also not as safe as putting it in cold storage or putting it in your wallet? I had I wouldn't do either of those. I wouldn't leave my money in a mining pool. I wouldn't leave my money on exchange for an extended period of time. Take your, take your currency and put it in your wallet. Now there are several types of wallets. Early on, in the early days, people would do what was called Paper awards. They would get a piece of code because that's all wall is as a piece of code on the block chain. I guess I could explain what the block chain, as you probably already know if here to this point, blockchain is just the ledger that thousands of computers all agree upon, right? That's why the blockchain is so hard, if not impossible, to scam or to fake, because thousands of computers have to agree on the exact same thing. So if one computer comes up, says, no, no, no, you owe you owe me an extra $100. Well, you're odd man out and it does. The other computers disagree with that, so it doesn't work. It doesn't change the ledger. Anyway. So what you wanna do is you want to move your money to a wallet that you control, a private Wallet now that private wall, it can either be a hardware wallet, a software wallet, or a paper wallet. And they each have their benefits. They each have their dangers. My favorite, I'm until you right up front as the hardware wallet, software wallets are not bad. Paper wallets are dreadful. Millions of dollars had been lost. And paper walls on a paper wallet is, is you have your code number, which is actually what your wallet is as a piece of code on the blockchain that says any cryptocurrency associated with this piece of code, this code being a wallet, belongs to you or me, right? Or whomever. Lots of people in the early days of mining would print that number on a piece of paper and then fold it up in a drawer or folded up. And I don't know, put it in there, real wallet or folded up and hide it somewhere. And you know, mice, Atum house has caught fire. Somebody's bathtub overflowed the apartment upstairs. And those pieces of paper were destroyed or lost. And I kid you not, millions of dollars had been lost. So what you need to do is you need to get a wallet. And there are several options here. We're going to, for the sake of this class, we're going to use a software Wallet. And I will walk you through that. It's very important that you set that up, okay? Alright, lets do that. 9. Setting Up Your Crypto Wallet: Well, if the desktop version, downloading the Windows version, since I'm running windows on this laptop. So the very first thing we want to do is secure this wall and make it so nobody else can use it so that nobody else can get into it and get any assets we happen to put in it. So first thing we're gonna do is go over here to settings and click on Settings, and then look across the top here where it says backup. Now we're going to type in a password. Hit next, type the same password in. The important part of this as the scene phrase, SCD, phrase, seed phrase. With this phrase, you can control your wallet. So can anybody else who has this SegPhrase so you want to keep it really safe and really private. But this allows you, if you, if you lose your hard drive, crashes, if your computer gets stolen, if you dump a soda pop on your computer. So get a pen and a piece of paper. We're going to write the SegPhrase down, then you're gonna want to keep it someplace nice and safe. I don't know that I would keep it on my computer, but less, less right this down. Word number one is soccer. Birth dry. You're gonna wanna do this for all 12 words. So if you ever need to get in or something goes wrong with your computer or whatever. In any situation, you can always, if you buy a new computer, you can just put this, you can download the software wall again and type in this 12th word phrase in your computer comes, you're on, your wall, comes right back to life. Now. I'm of course, I'm letting you see this as we go along. This is just for educational purposes. Because truthfully, I'm never going to use this wallet since I don't know who's going to see it, right. And the only person that I want to see my water information as me, myself and I and my wife. And she wanted to she could clear this up all this cryptocurrency out of my wallet and run off to the Bahamas. There she wanted to. This is called the SegPhrase, and I'll get that seed. This is the seed phrase. This is the most important security feature you have on this wallet. I'll look at that. You can print the phrase if you want to. Now it's going to ask you to make sure that you wrote it down and that you were paying attention. It's going to ask you which of these four words is In your seed phrase? Well, we happen to know that the word was seed. And finish. There we go. Now our backup is complete. This wallet is now our hours and it is now safe now it can do whatever we want to with it. So what we really want to do with this is I'm gonna go back to home. Is we need portfolio, wallet exchange. Let's go portfolio, look at it. Well, we know we have nothing in here yet. So the wallet or I'm going to need out of here is I need to go to now this wallet, this the software, the software while it will hold over a 100 different coins. But since you and I are going to mine Ethereum, What I want is right here, ETH, the theorem. I need to get the Ethereum wallet number. This is where we get the theorem wat number that we enter into everything. So I'm going to hit receive. And that's the number right there that comes up. Alright. So I'm gonna copy that. And that's the number you're going to put into. Well, not this particular number. Don't ever use this number because this is a dead wallet, okay? But that's how you end up with your number. So when you do this, this is the number that you would then put into any place that asks you, like naming the machines in our mining pool. They want that wallet number. Where is your money going to go to portrait cryptocurrency gonna go to this is that number. Now if you're reminding something else, say you're going to go mine. Bitcoin. Which unless you have, unless you have a an async, You can't do. But that would, you would go here and you would get the Bitcoin wallet number. Let's go if you wanted to say you wanted to deposit some Cardano, which a lot of people really like you would click on that and then there's your Cardano number. Cool. You got it. You get the, you get the picture. So that's how you set up your wallet. Now this, this is your wallet. Don't let anybody see the seed phrase. Put this in two or three places, copied down, put it in two or three places that are safe. Some people etch it on a piece of metal. I like titanium because if the house burns down, they still have it because they just go through the ash, just find a piece of titanium and it's all written on a titanium plate. Other people will write it down, put it in their safe deposit box. Some people will put it in a letter, send it to somebody else to put in their filing cabinet like a lawyer. Up to you, up to you. How ever you want whenever you steps you have to take to keep us safe, do that. 10. Make More Crypto in a Mining Pool: So what is a mining pool? That's a good question. I'm going to clear it up for you right now. Now, a mining pool is an interesting thing and it's really advantageous for you to use one. You can go out and you can crypto mine on your own if you wish. But there is strengthened numbers. So you can send your little minor OUT. Meaning, you know, out into cyberspace. You can tell it to go out there and mine, and mine, and mine. And you can send it to the areas where it works. Right. So your little minor is doing math. It's out there, it's doing math. That's out there, it's doing math, but it's doing it all by itself. If it never if it never completes the transaction, which it's very likely not to do since you're only getting a small part of any transaction. What happens is, unless you are the person who finalizes the transaction, you don't get any money for that transaction. Alright, you don't get, you don't raise any cryptocurrency. But now, say you and I, maybe your your Uncle Bob and my dad who lives next door does this too a little bit. And 10 thousand other people, we all join a pool. Now what happens is we have 10 thousand people who are all working on the same project at the same time. We're going to we're going to be knocking them out. We're going to be finding shares. When you actually find the nugget that you need to get to have the transaction done. You're going to find some shares. My dad's gonna find some shares. Your Uncle Bob's going to find some shares. We're all doing these transactions were all in a pool. Now, if I have a bad day and my computers aren't performing well, they're still working that are still putting x amount of effort into this. The guy next door, He's putting x amount of effort and this, the guy in bugged tussle is putting XML work in it. Whoever finds it then donates that to the pool. And then at the end of the day, everybody gets a small portion of that. So the 10 thousand of us finished one transaction, 10 thousand of us get one-ten thousandth of that transaction. Okay. It doesn't sound like a lot. But if you've got a card this running all day long and you take part of, I don't know, let's say 10 thousand transactions, you've made some money. Whereas if you're out on your own, I've seen the math on this. Actually, you send your minor out by itself. You have you're not going to do as well as if you join a pool just because you have all these people working on the same projects and you get a little bit of everybody's okay. That's what a mining pool does. Mining pools the way they make the money is they take 1%. Some take too. I've seen, I've seen some mining pools will take 3.5% of what you make. I think one percents fair, and I think maybe even 2% sphere. But the pool that I like uses will do sometimes between 0.91%. So that seems fair. And you have to have an accountant at an exchange, you have to have a membership in a mining pool because that's how I'm showing you to do it. Once you get good at all of this, you can do whatever you want. But this is me showing you how to do it the way to get you started the fastest. You're also going to have to have a minor management system, which I will explain to you in another video. You're also going to have to have a piece of software that will burn the USB key, which is Linux. And I'll explain that when I get to it. None of this is difficult. I'm going to walk you through every single step, okay? So it's just, this is just one more thing you need. You need to be a member of a mining pool. 11. Why You Need a Mining Manager: Now just like you need to be a member of a mining pool and you need to be on an exchange. You also have to have a mining manager. Now, just like exchanges and just like mining pools, there are lots of mining managers. The one that I'm using is because I've used others. And I'm telling you the one that I use now is in my estimation, again, everything in this course as my opinion, is the best. It's all really easy to understand. And it frees you up from a lot of those managerial duties that could just drive you crazy and you can do it on your phone. Where's my phone? There it is. I can be anywhere anywhere in the anywhere in the world. And I can check on my machines, on my miners. And I can see what they're doing and I can restart them if I need to. I can change things on them. I can add, make adjustments, all sorts of things. So it's it's a free account. All the all of these that I'm telling you, our free accounts. Okay. The way they make their money is they take a little bitty piece of what you're doing. The mining manager is going to charge you $2 to US dollars. I don't know what it's going to be if it's yen or pesos. But for me it's two US dollars for each rig that I own and I own several rigs. Hey, as I'm editing, this is an insert here and an editor's comment. As I, as I'm editing, I realized that maybe I could have said that a little more clearly. So here we go. Number one, if you if you're going to be mining on a telephone or a tablet, those those are free. There aren't any they're not that I'm aware already. Mining pools that charge for those. They have their own little system that we'll look at. Now as far as using a laptop or a desktop or your own custom minor, and you're joining a mining management tool, they will charge you $2 per rig. But one of these, there are two that I really like. One of them gives you your first rig for free forever. So there's never a charged for REG number one on the one mining management tool that I'm going to show you, okay? Then now you own one rig. You will own one rig. But if you're, let's say you're making a dollar a day, they charge a $2 rig. You have one car on that rig. It'll take you two days to pay for your manager for the month worth it. Worth it. Okay. 12. Controlling Your Mining Rig: Okay, so now what we're gonna do is we're going to go to our minor manager. From this program. You can manage the coins that you're mining. You can check on the health of your machines, your ribs, your mining rigs, and just generally control what's going on. Very cool. And the thing I like about this minor manager, there are many of these companies out there. But this company does a couple of things, right? Number one, if you only have one rig, it's free to run forever. Now if you decide to expand and the column workers here, but some places calm rigs, Some people call them workers. If you have more than one worker, then they'll charge you. I think it's like a buck 60 a month to manage that other rent-free which you can have you can have one rig with as many cars as you can make, run on it for free. So that's perfect for this class. That way you can experiment, see if you like it. And if you do expand two, you get one full REG and then decide what to do from there. But anyway, it's free, so that's cool. And any other thing is that I really like is they let you do profits switching from here. So if another coin overtakes the coin you're mining, and then suddenly better and more profitable, you, your, your system will automatically switch what it's mining and go for the more profitable coin. So that's a cool thing. So what I'm gonna do is go up here in the right-hand corner you see sign in. When you hit sign in, you don't have an access key and you don't have the two FA yet, which is a secondary security level where if you enable it, you know, and even if they have your access key, they can't get into your account unless they also know the temporary to FA number which they either sent to your email or if you have the Google app that has the automatic random password generator numbers, you can use that anyway, so you don't have an account yet. So go on up here and click Create an account, create a free account. And you'll put in your address here and you'll agree to the terms all that. Now, I already, as you might imagine, having an account here. So I'm gonna go ahead and close this out. And I'm gonna go to my email and show you what's going to happen. They're going to send you an email is going to be look exactly like this, except the number here is going to be different. The number here in the middle, that will be or your key for getting in. So you want to put that someplace secure because you're going to need that every time you sign in. And then you'll want to click here to confirm that you've got it and that indeed then opens up your account when you go back. Alright, cool. So let's do that. So now here we are on the minor management page. This is the market on this page that tells you what coins are available, what algorithms they use to do the mining. And you've got your dashboard over here. And you can look around through this would be where your workers are under control room and that sort of stuff. The clock tuning, that means overclocking because you can, you can push your GPUs, your cards. You can push them harder than they come from the factory. You can make them work harder. And the other cool thing is, is you can also turn down the amount of electricity they use. So what you do is you overclock and you under volt, but that means you get as much power out of it. I mean, there's much work out of it for as little input is you can't. So that makes it really profitable in two ways. You've increased the amount of work it does. You've decreased the amount of electricity it uses, and you will find a sweet spot at some point, you'll either overclock too much in your cards will start crashing cuz I just can't keep up. And conversely, you can under volt to the point where there's just not enough power and it'll crash because they just can't do the work. You're asking with a little bit of electricity you're sending to him. But there's a little range and they're a little sweet spot where they're really working hard and they're really not burning as much electricity. So that's what you're always aiming for. Okay. What we wanna do now is you and I, neither of us have any have any working rigs, right? No. No, no workers are no miners. No mining rigs are working. So what we're gonna do is we're going to set up a worker. Up here in the right-hand corner. You see this little button that says manage workers. We need a worker, we don't have one, so let's, let's make one. So we click on that. And we can discover new workers that are on this network, or we can add a new worker. And what I want to do is add a new worker. And I'm going to name it worker one, and it's in amd card. And That's team read as we discussed earlier. And the system I'm going to use is that you have your choice Windows or the system they have here, MS OS. And I'm going to click Add worker. And let's see what happens. Let's look at this. We're waiting for a worker O1, which means it hasn't booted yet and that's exactly right. So I haven't built the rig yet. I'm going to go get the parts and bring it here, throw on my desk and film that for you in a little bit. That has not happened yet. So this, this worker's does not exist. But I know that there's some things I need to do before this actually happens. And I'm going to need this right now. I am going to need to download the MS-DOS. Now. If since I told it amd that I'm going to, that's the team red cards because I'm gonna build this with an RX 578 gig. Remember, don't buy a four gig card, they will not work. So mine is an RX 500 series and RX 570. That's what I'm gonna do. Now if you have a radian seven, congratulations, are hard. As Moon rocks defined. You can either download this through torrent if you know what that is. If not, it's okay. You can download it directly. And that's what I'm going to do. This is going to probably give me a zip file. Let's see, continued to dashboard. Here it is as downloading is gonna take, gonna take me 53 minutes. Now, if you look down here in the lower left-hand corner, you can see it's gonna take a while, so you'll want to start that as soon as possible because we're gonna have to come back to that. Alright, so what I'm gonna do it, you can see right here that it has downloaded. So I'm going to right-click on that and hit extract all. Just gonna take a couple minutes. There we go. So now we've got the image. We'll save that for later. We'll come back to it. Now, I went and got a USB flash drive, little thumb drive or pen drive, whatever you call it. And this mining monitor system suggests that you use a 16 gig thumbdrive instead of an eight gig like the others that I've used. So I ran off to the store and grabbed a 16-bit. 13. Your USB Drive Key: Up till now, what you've been doing is joining things, right? You've joined an exchange, or you will join an exchange. You're going to join a mining pool, you're going to join the mining manager. So what we're gonna do now is we're going to download a piece of software to your computer because this is vital. This is probably the most complicated part of what we're going to do. We're going to download a piece of software onto your computer that you're going to run on your computer. And if you've got a USB and you'll, you'll need a USB stick. One of, one of these, right? You're going to need one of these, at least eight gig on it. Word of warning, if you ever see one of these in the parking lot or I don't know, on the hood of your car or just on the ground somewhere, take it and throw it away. Do not ever plug one of these that you do not trust or do not know into your computer. And there are scammers. Tangent, tangent alert. There are scammers who will buy these cheaply. I buy these like 30 at a time for another project that I do. But they can buy those and then put on two or three little bits of malicious software that you plug into your computer to see what's on that USB drive and it goes and it throws on malware onto your computer that is invisible. But since that person who, who coded it and alert says you now have control over someone else's computer. And they can get in there and they can look at your banking. They can, they can turn on your webcam and watched you dance around in your bath towel or whatever they want to do. So never, ever, ever, ever when you find that USB Drive, never ever put that in your computer. In fact, i i belong to professional convention. I'm a profession that has conventions once a year that I'm obligated by law to go to for continuing education for my profession. And they will pass these out at, at the, at the convention. Never take them. Because all it takes is somebody else to put it a little bit of malware on those and they've got control of your computer. It happens and I'm I'm sorry about that. Anyway. I digress back to on subject, okay, on point. So what we're gonna do is we're going to download that software. That software is going to, that software is going to burn. Cuz you're gonna go, you're going to buy one of these that you trust, right? Or you have one that you can trust, that you can sacrifice eight gig at least. Because we're going to, we're going to burn all the information off of it. That's going to be your key to driving minor. We don't have to put a hard drive on it. We're not going to run this with Windows. We're not going to run it with Mac operating system. I'm going to scare you. Ready, take a deep breath. We're going to run your minor with Linux. You saying you don't know Linux. Most likely you don't. Almost nobody knows Linux except the real tech weenies or geeks. And I'm assuming you're not one of them. If you're watching this on how to decrypt a mining, you're already way beyond this, Okay? But let me tell you this. It's the easiest, most effective, and there's a term called lightweight. It has a very small footprint, takes a very small amount of power to run this. And it's free. And it works so well. I've got miners that I plugged in three years ago that I've never even pulled this out of the machine one time that it just works. Linux just works. How cool is that right? You're not going to have to learn in new Linux. Because what happens is this program that you're going to download and put on your computer. And with this USB drive, I'm going to walk you through burning has called burning. Burning your key. Don't panic. My friend, I'm going to walk you through this. I'm going to fix that for you. 14. Burning Linux Onto Your Key: This part is arguably the, I don't want to say most difficult, but it certainly is the most foreign and least intuitive. So what you would do then is hit download right here. It'll take a few minutes, but it'll it'll start downloading. Okay, now it's downloaded for me and I'm gonna go here to my downloads and there it is, the very top thing. So I'm going to double-click that and start it going. Yes, I agree. I've used this several times, is absolutely safe. This is what we're looking for. We're going to flash from file. I need to go to crypto mining where I put that. There we go. That image is what we're looking for. That image is what you want to burn, is now you select your target. Which means you put in the 16 gig thumbdrive or flash drive. There we go. So that's why I'm going to select this, not my, not my scarlet disc but my scan disc. The cruiser glide and I'm gonna hit Flash and give it permission to do that. And we wait. And this could take a little while, if I remember correctly, it's it has been a while since I've done this. But, you know, patients by the magic of editing software, voila now are done, are just about done. So after it flashes, it's going to take a little bit of time to validate. But this is the USB drive that were flashing two and we see it's gotta config JSON it. That's very important because what we're gonna do is we're going to download the config JS from our management site. And we're going to drop it into this file and it's gonna say, did you want, you've got one of those. You've gotta config JS. Do you want to replace it? And we're going to say yes. And then that will, that will then turn our USB USB thumb drive or flash drive into the key that we then insert into our minor that runs the show, ladies and gentlemen, that's what tells it who we are and what we're doing. So just a second and this will be done validating built. And man, there it is. Okay, so I'm not going to flesh another right now. Pose this. Then I'm going to download the config JS, Okay? Download that config js right there, and it's starting. So the config, if we look up here in the upper left-hand corner, the config ab.js file has downloaded onto my computer. It's now here in my Downloads file on my computer. So I'm going to grab this and I'm going to drag it down her. I'm gonna drop it in my USB Drive. Now if your USB drive is not hear you because you've, you've just burned it and are just flashed it and all that and but now it's no longer visible. All you have to do is pull it out of your computer. Wait a second. Put it back in and it'll show up and then get back to this stage. We're back to this page where you can grab your freshly downloaded config ab.js file. We're gonna grab that. And we're just gonna drop it right here on top of that USB drive. And it's going to say, well, it's going to say the destination already has a filename, config ab.js. What do you want to do? Well, I want to replace that file, right? So let's do that. Teaching now in theory. And what the, what do they say in theory? Practice and theory are the same thing. But in practice, theory and practice are not always the same thing or works that effect. Now what we do is we pop this out, take the jump drive out of your computer. And we're and we're going to have that to stick into our minor. The very last thing. And that, that should, once we've got our Minor built power are minor or if your minor is already built, depending on if you watch the video, watch this class all the way through and then decided to go build it. Or if you built it as we went along, you know, I can't see what you're doing. So that key that you've just made, that jump drive is the key to driving your minor. So put us someplace safe or put it into your minor. That's what I'm saying. After you add your new worker, it'll bring you to a page, something like this. Click on worker. And there will be a red bar across the top that says that you're donating to them. And until you update the e'th wallet, your minor will work, but donate your money to them. So what you do is you click that update yf, and it'll be a red bar on top. I'm sorry, I should have taken a picture of it and I've I've I've already deleted this and I've tried to go back into it and it wouldn't let me do it. So just a reminder. If you don't remember where your x, your wallet number as you go up and double-click Exodus, type in your password. And you click this little arrow on the right side that goes that Cisco there, that I'm bump, bump. And you click on a theorem because remember, there's an update on the say remind me later so we can just go through this. You always want to send a theorem to endothelium wallet, bitcoin to a Bitcoin wallet, whatever else you may have to that type of wallet. Because if you send a theory into a Bitcoin wallet, your theory and is gone forever. So let's do this. I'm checking guesses. The Ethereum wallet. Yes, it says right here, so I'm gonna hit receive. And that's going to bring up right here this blue number. That is my Ethereum wallet number. Now, you may feel free to send as much a thorium as you want to that wallet anytime you want. And I will say, thank you in advance. So what you do is you just go over here to this little, this little icon copy, copy that. Now that's copied to your clipboard. You can now x out of here and go back into the sea it let's see if address editor will that do it? Yeah. No, no, these are all this is close but no cigar wallets. Oh, I'm sorry. Right there. Wallis. Okay. Here we go. See how it earlier is said demo right here. And it had their wallet number in there. If I were if I were at the moment was ExoMars stellar Lewin's, I don't I don't know off the top of my head. If I were mining for NMR or fire mining for Bitcoin and our Sending it here, they would be getting the money, right, as they said, this is for a donation address. So what I did is I came in and it had their red demos sign right here and it had their address for eith. I just took that out. I just put mine in and pasted it and then hit the save button over here at that point. Let's see if that'll do it right now. So I'll change this to, there we go. And there's a green Save button. I change it back to the exact same address. And save. It'll take a second. And we are hip and groovy and cooking with gas. You did it, you did it. My friend. Now, let's go back and see. Here we are my workers running. It says, and this was about right. That card usually runs between 29.5 mega hash and sometimes 30.5 mega hash. So it's pretty darn good card. Here would go. Right now, this program is estimating that I'm going to earn a Buck 98 off of my one GPU that's running at the moment. But, but that's all for now because we just wanted to be up and running and we have successfully gotten ourselves up and running. 15. Your Used Gear At Work: Alright, let's talk You and I just for a second here about do you buy stuff new or do you buy stuff used? A number of schools of thoughts in this. And the possibility is, is just entirely possible that you don't have a choice. This is a, this is a constant battle getting new cards because at the moment as I record this, mining is hot, hot this card. I paid about a 100 bucks for it. I paid about a 100 bucks for that card yesterday. That card was making about $2.50 a day. So let's do the ROI on that. $2.50 a day to a $100. Let me get my calculator. You probably already did that in your head. So the way I figured that ROI on that card, on this card right here, which is, you can see it x Fx. It's a 578 gig, eight gig. Do not buy anything that has less than eight gigs. You will find deals on four gig cards, on three gig cards. And to get cards, they are worthless. And you can find gigs on. You can find deals on six gig cards, which you can still use. And they'll probably be good for quite a while. And they're pretty good cards, like the 1660 is a really good card. But at some point, it's going to DAG out. I'll explain that. Just the point is, do not buy a graphics card that has less than eight gigs, okay? Unless you get a 1660 or 660 super or 1660 TI, those are pretty good, but they've only got six gig. Okay. We're gonna, we're gonna do the ROI on that card. I paid a $100 for that card. So a $100 divided by yesterday I was making $2.50 to 251 actually, I think that's what it was. So to 51. So that card pays for itself and 39.8 days. That's what i'm a month and a week and a couple of days until in you right now, unless you have friends who have gear that they wanted to just let you have or borrow or buy for cheap. You're not going to find that card today for a 100 bucks. I say that not knowing what, you know what all of this is fluid. The market changes back and forth. The price of gear goes up and down. The availability goes up and down. I don't know what you can find it for. I know that I found that card a year ago for a 100 bucks today. That same card is about $250. I know. Right? That's because it's making so much money. So at $250, if it made $2.50 cents a day, it take you a 100 days? I'd take up yeah. A 100 days to pay that car off. That's your ROI. So the question is, is do you buy new or used? Well, the thing is, is every new card that hits, hits the market is out of stock. You can't buy it online. It's hard to find these cards online except for eBay. It's really hard to find these cards online new, there are some great cards coming out like I, there are cards that are making 5, $6 a day right now. Good luck finding one. You know, you're not gonna be able to find it at your local store. I went to the electronic store yesterday and I walked in and I said, what are you looking for? I said I'm looking for GPUs. Like I laughed because I walked over to the section. He said, yeah, if we have any there in the glass section there in that big glass thing, the cage locked up. I went over there. There was nothing but bear shelves in that cage. That's what you're gonna find. You can't buy them online. You can't buy him in person. Or you can on occasion, if you're lucky, a snot, right? Generally what's going to happen is you're going to find two ways, three ways that you can get these cards. Number one, you've already got it. Number two, you've put your feelers out to all your friends and somebody's got a card, they'd like to have a few 100 bucks. Maybe. They can upgrade their card. They've got a line on new cards so you can buy him a card by a card from them for use. Or and here's the worst bit. You can buy it online like at eBay. Sculpt. The card that I'm looking for right now that I think represents the best bang for the buck other than I mean, I really like I mean, holy smokes. I loved the 578 gig, the RX 578 gig, AMD. I love that card, but I'm looking for 30-60 t i's they MSRP, the manufacturer's suggested retail price is $399. Good luck. They are selling on eBay for seven hundred and fifty, eight hundred dollars at this moment, twice that because what happens is you've got a guy who's kind of the middleman between the distributor and the stores. He takes half of the cards that he gets and he sells them on eBay because he's making bank, right. And making a boatload of money instead of the the meager amount that he would make by moving it on to the distributor or moving it on to the retail. So at the moment in the market, do you buy new or used? Well, you may be buying used just because that's all you can find and there's nothing wrong with used equipment. Well, I take that back. And there's what used equipment might be all you can buy. If you can buy new equipment, Good for you, if you can afford it, and if you don't mind doing the ROI as we just did and figuring out what the, I mean, if you're paying it, there's some cards out there for a 1000 or $1200 if they're only making a buck and a half a day, you're looking at, you know, three years to pay it back. I wouldn't take that risk. So it's all up to you, my friend. You are the one who has to do the math. You were the one who has to figure out your, your willingness and your exposure level and what you're willing to do. I'm willing to pay some money for really good cards. I'm willing to pay 50% over retail for a good 30-60 TI. Right now I'm seeing them at 70, 80%, even a 100% over MSRP. So that's just math that you've got to do. Now if you're a guy, I bought this card for about a 100 bucks. Actually, what happened is there was a guy who was dismantling his his form. Because the other thing that you have to figure it out into your ROI is your electricity. So his electricity rates with so much he just said I'm done with undone with mining. So he was selling all of this stuff. So I bought a bunch of cards from him and about and it was all, you know, buy it no returns because I'm going out of business and I was willing to take that risk. And about 12% of the cards I bought from him were crap. They didn't start. I couldn't make them work. Fans didn't work, which is a minor thing cuz you can replace the fans. So that's a good thing. If you can get a good card and the fans don't work, you can get replacement fans for about ten or 12 bucks a set, so that doesn't hurt at all. But when it comes to the question of do you buy new, do you buy used? You have to do the ROI and you had to figure out what your, what your comfort level for buying used. Because there'll be there'll be time. I've bought gear from people and it's been bad, ran for a while and then diet and there's no warranty unused to get on US gear, you know that no warranty. And I've bought new gear that I thought was just too expensive. I've bought new gear that didn't work. But the thing about new gear, if you buy it and it doesn't work, you've got a warranty and you can bring it back. I've done that with a couple of motherboards. I did it with CPU, central processing unit. And what else have I returned? It's a couple of three things, right? Because you get it, it's new. You plug it in, doesn't work, sent it back, and you get your money back and you get another one. So that's that's my friend. This is all up to you. I can't tell you what the right thing is for you. I don't know your situation, but I do know that a great measuring tool is the ROI. 16. R.O.I. Your Most Important Number: Let's talk about ROI. What is ROI? You may know this already. Roi means return on investment. Okay, how long does it take for you to break even? Well, that's, you know, that's a question that only you can answer. It's gonna take some math and everybody's situation is different. And whenever I started mining, I had some pieces and parts that I could use. I had plenty of lumber at my house, so I was able to make some mining racks. I think I also had, I think I had a couple of CPUs and maybe a motherboard. But the thing is, is you can either buy this stuff new, you can buy a used. You may already have some of the parts that we're going to need to do this or you can scrounge about and ask your friends, everybody's got an old computer. A really cool thing to do is you can get on the phone or you can get on your social media or whatever and say to everybody, look, I'm doing this project. I'm looking for donations of old computers. When you do that, you get some really cool stuff. You get motherboards, you'd get sticks of memory. You may actually get some really cool GPUs, graphics processing units. There is a actual dollar cost involved. There's, you know, you can pay for stuff with time, you can pay for stuff with money. And a little bit of effort sometimes goes along way. So you might be able to find a bunch of computers at your friends. Say, Hey, just take this, just take this, just take this. And we can use old motherboards. We can use old CPUs, central processing units. We can use old PSUs, which are power supply units. We can use old memory as long as it's four gig or better, right? Let's say that you have a motherboard and you have a CPU with the fan on it. And you got 444 gigs of RAM on your memory stick. Okay, let's see. So we got, we got all that. Now all we need is a GPU, a graphical process, a Graphic Processing Unit, a card graphics. I've got poem. I got one right here. Now you go. This is, this will snap into your motherboard. Let me write here. There we go. So that might be, that might be the thing that you have to buy. That's often the thing that people have to buy. Ibm, I bought a truckload of those things, but everything else. You may have laying around the house. You might be able to scavenge, you might be able to, to have gifted to you, you might be able to buy on the US market, Craigslist or eBay. Where else? Facebook has a marketplace or ask your friends, okay, so let's say the only thing that you really have to buy is one graphics card and a, and a cable. Ok? So let's say that graphics card costs you a $150 and the cable is another five. So what did you into? A 155 bucks. Alright. So with that card today, your card is making a dollar a day. One card on the Internet. Mining cryptocurrency makes $1 worth of cryptocurrency a day. How long does it take you to make a 100 and to make your a $155 back? Let's add another $10 because you had to take your friend to lunch to have him give you the motherboard? A hundred and sixty five a hundred and sixty five bucks to get your rig up and running. That means your ROI is a 165 days because you're making a dollar a day, right? So at a 166 days, what happens is you're now making profit, pure profit minus your electricity because these things don't run on Sunshine. Well, unless you have the solar panel, which hopefully you do. Okay, so that's how you figure your ROI. How much money do you have into it? How much money are you making a day? And what does that equate to in number of days. And you can mark that on your calendar. I certainly do. Whenever I've been known to, like when I buy a card like this, I'll put a piece of tape on the back and in magic marker, I'll write bought on January third. It's making a buck a day. So I assume all things being equal coming because it's going to go up, it's gonna go down. I mean, your profits are going to go up. Your profit is gonna go down because it fluctuates the price of cryptocurrency. So I know that a 165.5 days from January third, which is what? I don't know, that 5.5 months. So sometimes around the fourth of July, I'm gonna make my money back. Very cool. And then from then on, we're talking gravy. Okay, so that's how ROI works. 17. Your Cables De-Mystified: Let's talk about cables. Cables are very, very important. First thing I want to mention about cables is this. There is no standard for cables. That means a couple of things. Number one, there's no manufacturer, there's no standardized manufacturing. Hallmark or that these guys are trying to get to that it'll carry X amount of power. You know, we'll do this many ohms or amps or whatever, all that stuff which I don't understand, maybe you do. The other thing is and I either mentioned this and you've seen it or not, or Wilmington that when I get to the PSUs, the power supply units, power supply units have proprietary cabling. That means a power cable from one power supply unit may or may not work in another power supply unit. What does that mean? I'll tell you from personal experience. That means a cable from one manufacturer plugged into a PSU, a power supply unit from another manufacturer may set everything on fire. And I mean, real fire. Fire with flames, fire set in your wall on fire. Voice of experience, my friends. So do not skimp on cables. Makes sure that it's from the manufacturer of your CPU. And make sure that it's the correct model number. Because like Coursera, for instance, says that this is the PSU that I've been using and I really like I was using other ones before that. But I graduated or I've migrated over to just using Coursera's course, I go with that. Corsair has like four or five different levels. Of Coursera has like four or five different levels. I don't remember the exact levels that they are, but it's like they have the AX series and then they had the RM Series and then they have the US series and they have the I don't know, the blue rhino series or whatever they happened to have. You have to go to the website and you have to get their chart and say, okay, I have this model number. Which series of cables work with this model number? Because you can set things on fire if you use the wrong, you're still using the same cable from one company, but it comes from a different level of models. Fire, okay, can ruin your day. First off is the big one, is the one that plugs into your motherboard. Has got these ends here, but 24 pin, and I don't know, let's say can we see that 24 pen is it's the only one that looks anything like this. It's unlike any other cable. And it's 24 pins. So it will only go in one place on the motherboard. That's the thing about this whole thing. If you can plug things in and unplugged things. If you can plug in the lamp, my friend, you can build a computer. That's all there is to it is all just plugging stuff in. Now let's look at the CPU. Power is going to be eight pin. There it is. Eight pen at the, the power supply, right? And then it goes into the board, usually an eight pin, but not always. Sometimes it'll be a four pin. And if you look really closely, I don't know if we can see this. But right here there's a break in this one. And a break on this side. You can get a knife in there or a screw. All There you go. I just forced it apart. And he goes now you have to for PowerPoints, power plugs that can go on if you have a four pin power and the, the zodiac motherboard I have, which I have one or two. The Zotero B15 motherboard takes a four pin, if I remember correctly, and I absolutely, I loved that board as a great board. So let me put these back to get them get my get my glasses. And let me snapped this back together. And we go snapped right back together. Now it's an eight pin, eight to eight or eight to four. And just leave for the pins dangling if you need to. Generally, it says on it marked CPU. So we've talked about your 24 pin for the motherboard, and you're eight pin for the motherboard. Your mother well, once supplies power to the motherboard, one supplies power to the central processing unit, which is on the motherboard. So basically we're talking motherboard here, right? Okay. So the third set of power that goes to your motherboard is 99.73 to 6, 5% going to be molec. The third one that will power the board is going to be the mole x. Again, it's going to be a plug on this and that goes into the power supply. But this is only six pin on this end. And if we look over here, this is what mole x looks like. It's got 44 pins in it. And sometimes they had this little squeezy little wings on it that are really silly. I don't like I've said before, more Lexus. Fine. But it's just fine. And I don't like molec as much. It doesn't carry nearly as much power as you think that it might. So again, never plug in more than two. You'll see this one's got probably for yet does Scott for plugs on it? Never plug more than two and to any devices. Okay. That's that's your limit. That'll plug into the power supply then that will plug into the board. So those three cables that we looked at, what power our board, the the motherboard power supply, the CPU, central processing unit power supply, and then the mole x, which is going to drive our PCI slot. There will often be one or two places on the motherboard for mole x to be powered in. And you can see here, there's a place for one mole next to plug in. And if you look at the other end, there's another place for a mole x to plug in. What this does is this powers the PCI slots, adds extra power. Those slots that will be taking in the video, the video signal. Sometimes you have to have extra power because if you put, Right now you and I are planning on just building a rigged only has one GPU on it, right? But you can put, I've got rigs that have six. I've built rigs that have had 13. The more cards you have on a mining rig, the less stable you're mining rig is. I've got a couple of things out there that only have three. They can run through hell and high water. Five, no problems. You get six. They started getting a little sometimes squirrely. 78910. You very often, nothing but headaches. So I like to limit the number of cards I have on a rig, right? But that's all up to you and what you wanna do. But we're just building rigged with one card. You probably won't have to put them all exon. Because if we're just doing one card, your largest PCI slot, which is called the PCI E6. As opposed to the PCE ones, generally has enough power in it to drive one card. Number one is a piece CIE 16, and then the next five or PCE ones. If you start stacking GPUs, you may start having crashes and faults and things not working. And things just really, squirrelly is a really excellent term for this. Thing's just may turn squirly. If that's happening, you need to put on your mole x, and that drives extra power to the PCBs. The next cable we're gonna look at is called a saddle. Now this is again, this has, this is the Santa Cable. Six pin goes into your power supply. And then this is what a sadder looks like. I think there's, if I'm not mistaken, there's 19 pins in there. But the real feature, as you will see that this slot isn't an L shape. It's got a little weighing on one end, right, right there on this end. So it will only go in one way. So you try to plug stuff in, it won't work. Then just flip it over. It'll go right in. These are great. Again. You'll find them all day long with four plugs on. Only ever use 22 is your limit okay to these plugs are cheap. I think there are these quarter sheet, maybe 5-7 bucks apiece, Max. And I I've gotten them for a lot less. I bought them for more. But the thing is by extra plugs. Don't set things on fire. Which oh, let me show you. Or you'll be putting duck tape on stuff like this sparks. And that's just a euphemistic way of saying this thing catches on fire, so don't plug it in. Okay. So don't be that guy. And sadly sometimes that guy is me. The sadder runs the risers, which are the expansion slots for the PCI PCBs. Now the last cable we need to be acquainted with the one that drives the GPU. So right here, you can see that, that plug that, and you can see that it has a slot for eight pins power. So this is going to be the power supply to your cards, okay? It's eight pin on one end. And some of these will go 810 to eight pen. But generally what you're going to see are often what you'll see is there will be a splitter. So this one goes from eight on this hand to two plugs on this end, both of which are called the six plus 2s. And that's because there are six, then there's two more, right? You see that there are six plus two. So you kinda have to push these together. And it's best if you bring it from the bottom and push it onto the plug. If you try to come down from the top is a little piece of plastic. They'll usually stop you making a complete plug so that then in this case is eight to eight or eight to six. If your GPU uses six pens or some actually use eight, and then you plug in both of these into a mux. I've got an old 470 that takes an eight pin and six piano. So I had to plug all this in to run just that one old card. But that's what you have. And you can run two GPUs, offer this, but only two again, don't we stack and I'm even though you can buy another splitter and put on hair and love us, glitter and put on there. Then you're running for a recipe for a fire. My friend. And some of the new high-powered cards have as many as 12 and I think even 16. Some GPUs have proprietary plugs in. But what they will do is often they will send the exact right cabling that you need. So there you go. Or an adapter. 18. Gear Generational Clarification: The bill that we did in this course is on Qian seven, right? Generations seven of stuff. But it doesn't matter as long as your motherboard and your CPU and your memory are all happy with each other if they're all the same generation. Now a friend of mine, I told you just put the word out on Facebook or someplace that you're looking for old computers. A friend of mine gave me an old computer. And you can see right here, I just I just snatched I took the entire motherboard, add it here. I didn't even dissemble it. This is simply you think there's real power supply. I couldn't use it because it didn't have enough power hookups to it. But I just took out all the bolts, pulled that motherboard out with the CPU and the fan and a memory all on it. And that's this unit right here. I just snatched that whole thing out. I don't even, I don't even know what generation that motherboard is, or the CPU or the memory. It just, it all came as a unit and all work. I've put it all together and I put these I put these GPUs on it. If you look over here, you can tell it's mining. I don't even I went he said, I don't even know what those are. But you can use any old equipment that all works together. It will all dry it because mining is not the memory intensive as GPU processing intensive, That's where the GPU cards do. The memory can be all. I mean, this this computer is, is I've got 1214 years old. 19. CPUs to Use: Let's talk about central processing units. This is the brain of the computer. And fortunately, crypto mining does not take a lot of brain power as far as running the motherboard and the ancillary activities is concerned. All of the, all of the real computing power happens in the GPUs, which we'll get to in a minute. But the CPU, you can use older equipment. And by older, I mean cheaper. Okay. Now, I've got to tell you a couple of things before I, before I give you the model numbers, I'm gonna give you three model numbers that I really like. And I'll tell you which is my favorite of the, of the three. But there is a, a a geneology parentage system, a generation system. That's what it is. There's a generation system for your, you have to have these three things in common. They all have to be the same generation. If you're going to use, I think we're up to like Donald, tenth or 11th Jin now is called Jin, tenth or 11th gin in motherboards and CPUs and memory. Now, I suggest use everything that's seventh Jen, Jen, generation number seven. That's what I use. The gear is inexpensive, it's dependable and it's available. Okay? So as far as CPUs go, you don't need a lot of computing power, as I said. And again, anything that's seventh Jen will work. But these are the models that I like. The seller on 3900, the seller on 3930, and the 4560. And they're all seventh Jen. So that's very important because you have to have a seventh Jen CPU to work with the seventh Jen motherboard. Otherwise, they will not work and you may do damage both your motherboard and your, your CPU. Now, I like I told us, would tell you my favorite. The one that I have the most of running on my Riggs is the the seller on 3930. Not necessarily my favorite, but it has two cores. Okay. So it's that's more than enough. It works. It will drive your mining rig without any problem. The seller the seller on 3930, you can find them still for fairly inexpensive. And very often you can still buy them new. And when you buy them new, very often and you can check this on your own. But you get not only the CPU, but you get the cooling fan in the same box. And the cooling fan has thermal paste already applied to it in the right proportion. And it's a really handy, dandy way to go. Now, I really like the 4560. The 4560 is a slightly newer CPU, slightly newer chip, they will call it. And it's got the two extra threads so it can handle anything. If you have a burst of sudden computing power that's needed, that can certainly handle it. And by coincidence, the rigs that I have that have the 4560 are slightly faster than my other rigs. So over time, if I can get the if I can get the the the 4560 for the same price, I get 3930. Over time, the 4560 will pay for itself and then make more money faster. But it's up to you. They are fine. All those CPUs or find anything that seventh Jen is fine. But those are my favorite set of all my favorite being the 4560 because it's got that the two threads per core, but the 39, 30 with two cores as adequate. Okay, so there you go. The 4560th, very often, significantly more expensive. So there are times that I've, you know, bought 3930 just because that's the limit the amount of money I had, I could get a new 3930 and a fan for about the same price, I can get a used 4560. So figuring my ROI and looking at how much money I had in my pocket, I made that decision the same way that you make every decision in your in your financial life too, I'm sure. 20. GPUs How to Choose: Alright, everybody's favorite subject, GPUs. And I've shown you my, I just happen to have one on my desk. It is an RX 570, again, eight gig. There are two main players at the moment in graphics cards. Number one is called Team Red and the other called Team Green. Now Team Red is the AMD based graphics card and their logos in their boxes and their merchandising in their advertisements all have splashes of red on them, so they're called Team read. The other group is called, called Teen green. And they are based on the NVIDIA platform. So there are people who are all in on Team Red and there are people who are all in on Team Green. And there are people like me who love them both, that there's about to be a third player. And maybe by the time you see this video that third player will be out. And that is Intel. Intel has been making rumblings that they are going to get into the GPU game. They want to be called Team Blue. So hopefully that's coming in and hopefully that will a, give us more availability of cards. Because as I said earlier, and I will say again, and I'm saying now, finding new cards as darn near impossible. Even if you want to buy them. You good luck finding them. I hope you do. And the scalpers are doing great amount of trade on the US, on the US market and the auction sites and those kinds of things. Sometimes the cars are going for twice as much as MSRP. So the cards that I would use if I review or any card that you can get your hands on. Because at the moment, within reason, at the moment, just about every card that you can start mining is making money and that looks like it maybe, you know, again, no guarantees and your mileage may vary. But just about every card out there seems to be turning a profit. Different cards cost different amounts. I like the RX 578 gig. That's, that's mostly what I'm mining. I have some older for 70 years and older for eighties. And they're fine. But those cards are like five or seven years old now. And I've replaced the fans on almost all of them. And someday they may die because they're old. The other cards I like are the, I like the Nvidia. I like the Nvidia 30-60 TI. That seems like a really good bargain for the amount of aid that, you know, you've got a retail price that you're paying for it, plus this gotta return. It does so much hashrate. Hashrate, meaning how much work will that card Do you know how? I mean, you've got workers when you're digging your Goldman, you got guys get out there and they bust their butts and they dig you a lot of gold and then you've got employees who yeah, kinda coast along. Yeah, the same thing with, you know, different cards. So Jaccard, How much does it cost? What's this hashrate? How hard does it work? And the other thing is how much electricity doesn't burn. Because we're looking at, we're looking at our overall all price of having this thing run. So you've gotta do the numbers, you got to look at those. And for me, my personal opinion, I think the RX 570 and the RX 588 gigs do a great job. But, you know, if I can find a 470 or for 88 gigabyte those to, again, do not buy any card that has four gigs or less. It just they will not mind any longer because of the, what's called the DAG, which is e1, which is the bite of the size of the chunk of the information that your card has to process comes in a DAG. That's what it's called this the size. If you have a DAG, that's two gigabyte, it easily business side of your four gigabyte card to be processed. If it's a three gigabyte, well, it takes up obviously more space, doesn't. If it's a four gigabyte DAG that goes to a four gigabyte card. You almost have no room for processing because the DAG takes up all the computing space. So if you have a 4.2 DAG that goes into a four good card, it won't work. So that's where we are now. That's why you need an eight gigabyte card. Don't buy anything with less than four. Alright, I think, I think I've made my point on that. Now. The other thing you need to consider is what coins do you want to mind? At the moment, at the recording of this, there are several hot coins that are being mined. Everybody knows Bitcoin, hard to mine Bitcoin, it's really not profitable to do it on a GPU. There are cards called, there are machines called A6, ANSI-C, which is called Application Specific Integrated Circuits. Those are expensive, hard to get a hold of. And there are some other problems with those that I don't even want to get into with policy, politics and China and America, and who's controlling what and who's working behind the scenes. And some people have claimed that they've gotten an async brand new from the factory. That looks like or smells like it's been mined heavily for six months because yeah, we'll get that right out to you. And then six months later it comes and it looks like maybe the factory test drove it on your behalf right before they sent it. Anyway, we're talking about GPUs, not A6 and F GPA cards, which are expensive and really hard to program. So we're not even talking about those were doing it the easy way. That is most likely to produce some income for you and lots of fun with very little headache. That's what we're here for is the fun. 21. Mixing Amd And Nvidia Cards: Mark, how's again, ask me another question. Can you mix cards? The answer is a solid, maybe. It's possible like here, I've got an RX 580 and an RX 570. On another rig behind me, I have an RX for 70 and our export 80 of 570 and 580, all in the same rig. That's okay because the architecture is the same. They're all a MDs. When you get into trouble is if you jump, well, there's architecture that is built upon and series numbers, like those numbers will those law work well together because the 474, 85, 75, 80 are almost the same. If I were going to try and put it on a 5600 or 1600 x t, it would probably clash. You just have to try it. The other thing is if you start trying to mix AMD cards and in video-based cards, 99.73726% of the time it won't work because they have different, you have to put different software, mining software on your jump drive, on your little thumbdrive here. And that's usually specific to an architecture, either AMD or NVIDIA. Now, some motherboards are happy with that. They're okay with it. There's one motherboard out there that will let you put on 13 cards. And nonetheless, it go on 19 cards. But they insist you put on like seven NVIDIA cards and six AMD cards. But that's like only one or two motherboards and like countless other books out there. You're going to be a lot happier if you stick to putting all of the same type of family of cards on just one Rick just on one motherboard, that will save you so much headache. Like I've said before, I really like putting on just six cards. That's where I kinda top out. Because yes, I put I built 13 rig cards are 13 cards rigs, but they're unstable. These I plug these in. We may be CO binding. We can, we can, we can go on vacation and these will run. The other thing I'll do is, you know, the old trick of starting and restarting something. I'll put these on their Wi-Fi switches. That wave wherever I am in the world, I can restart a machine if I need to. All right. I think I've covered that. Thanks a lot. 22. PSUs Safety & Ratings: Power supply units. This is, this is quite the subject we needed to speak about here. If you're going to be getting into mining and you're gonna do it on any skill whatsoever, you need to start thinking about your power supply is now, as I've already mentioned to you, the power supply cables do not interchange between brands and sometimes not even between model numbers of that same brand. So you have to think near the beginning what you're going to do part of this as, you know, if you've gotten it for free and you're starting right now again, this is just our primary rig. This is our first time building a rig. That will end. We're learning, this is what we're using to learn how to build mining race. Later on you can expand, you can, if you buy some equipment now that you're not happy with, but it gets you Mining, at least it got you mining. Then you can sell that equipment and buy new equipment or other equipment, right? Okay, so we're not discouraged. If you have a power supply, you've gotta power supply. So that's a huge start. Okay, so good for you. There are three types of power supplies. There's non-modular, there's semi modular, and there's modular. Okay? Now, the, the non-modular means your power supply comes with all the wires that it can handle. And they're all sticking out of the back and you can't detach, you can't attach, you can't move them around. What you have is what you have. Now that limits what you can do, but it also is a safety factor and making sure that you don't overload your power supply, okay? Because you're not going to, you're most likely not going out. Maybe you can, maybe your ingenious and you can figure it out to overload it. But generally what's going to happen is they won't have more plugs than what they estimate they can power on the unit. Now, the CEMA modular might be my favorite because it comes with the similar modular comes with two cables already attached. Those cables, as you remember back to when we were talking about cables are the 24 pin that runs the motherboard and the eight pin that runs the CPU. All of the other cables on that power supply as a semi modular, are able to be plugged in an unplugged and swapped around and used how how how you would want to use them. So I like that one. A lot of the other is completely modular, which the only difference between the semi modular in the modular is the 24 pin and the eight pin power for the CPU are not attached. They are completely modular. That's cool to power supplies are rated by the amount of power they can output. You will find them. They say 650 watts, 700 watts, 500 watts, 300 watts. I, most of my rigs run with a 1000 watt PSU power supply. Now many of the, I've, I've got some 700 and I've got a 652, I believe. Because that's what I started with was I thought OK. 650, that'll do it. Well, I quickly outgrew that. But that's what I had and that's what I used. And I hope you do the same, right? Because we're doing this as cheaply as possible because we want to hit ROI as quickly as possible. Now, they come with ratings. Now the rating is, It's not rated. You can pretty much realize it's not rated, so it's, it's not really efficient. But PSUs come with ratings. Bronze, silver, gold, platinum. There's something else that ought to do it. Go for the most precious metal that you can afford. The, there's not actually any, I don't think any platinum in a plat number, there may be golden a gold. What happens is like with gold, that, that says that this power supply unit is 80% efficient. That means at least 80% of the power that goes into the power supply comes out of the power supply to power your motherboard. So that way you're not burning lots of electricity just into heat. Because power is going to either come out as power or come out as heat. If you have a bunch of cheap power supplies, you're going to heat up a room quickly, and that heat equates to lost dollar. So the, the higher quality power supply you can buy, the better. Now, you also have to figure out the rating. What are you going to do with this power supply? Each GPU is going to burn a certain amount of power. Your, your motherboard is going to burn a certain amount of power. Your CPU is going to burn a certain amount of power. So what I like to do is this, figure out how much power is being used or will be used. And you can find all those, all those numbers are on the internet. How much power is my motherboard going to use and my GPU going to use. And then you want to have a power supply that is at least 20% higher. So my rigs outside, I've got enough GPUs on them. And I know, I know my CPU, so I'm running about 800 watts or RIG, running six cards on a rig, it's about 800 watts, sometimes 8-10, sometimes 70-90. While I run a 1000 watt power supply, 800 watts worth of draw, that's always a good, that's always a good rule of thumb is to, to run your electricity and your equipment at about 80% that we've got some buffer in there because you don't want to run your electrical stuff at a 100%. That's dangerous because it may do it for a while, but at some point if you have a failure, it could be catastrophic. It can burn stuff down. No, no Bueno. My friend know buoyant mu0, no Bueno or no movie Bueno, however you would say that, alright, onwards. 23. You Need Less Memory Than You Think.: Alright, now we're gonna talk about memory. That's the, and you'll sometimes hear these referred to as sticks of memory. That's because they look like memory on sticks that then snap into your motherboard. You wanna make sure that a couple of things. Number one, since we're building a seventh, Jen, We have a seventh Jen motherboard, We have a seventh Jen CPU. You want to have DDR for memory. Now, we're gonna take our four gig of DDR for memory. A memory stick here. Not, not fancy, not pretty, just, just utilitarian. And we're going to go into slot memory, slot number one back here. Okay? And we're gonna make sure that this little notch, that little notch here is going to line up with this notch here. Alright? And this is going to go into slot number one. So let's do that. I'm just going to eyeball it, make sure I have it on the right way, which I do. It would be off by about a half inch that way. Flip back around. Just flip it back around. Just take it and slide it into the slot number one and push it down until it solidly in there and it clicks in place. See this little lock here will snap down and make sure that that lock will articulate back and forth. So make sure that it's out. And then when you push it in, it'll snap it and hold it in place. So one stick of four gigabyte DDR for memory will power your mining rig. Remember, this is not real memory intensive, Not a lot of calculations going on with the CPU on this. So we're looking at bare basic minimum. Eight is fine if you have an eight gigs, Dick, I see people put 16 gigs on there. That's a little overkill. You don't need that much. I mean, it just sits there. It doesn't get used. It goes to waste. Why not have several four gig sticks that you can then spread across more mining rigs as you grow. 24. How to Turn On Your Motherboard: Okay, Abraham Lincoln, right? You know him, he tells the story or the anecdote or what have you, that if he had eight hours to cut down a tree, who has been the first seven hours sharpening his ax. That's what we're doing here. I know some of the stuff that I'm touching on and destroys. I tell you that like holy cow, can you get to the point? My friends, this is the point because little nuggets of wisdom that I'm dropping on you will save you hours and hours and maybe hands full of hair when it comes to actually building and getting everything to work. Okay, so one of those things that you go quite bring that up now is this how to turn on your motherboard? I'm really, really yes. That that has caused more people to send back motherboards thick and they're broke than anything else. And cause more frustration than anything else. How do you turn the darn thing on? There's some of them now, amazing. Some of the newer models will come with an on-off switch. That's what a great idea that is, right? But generally what you're going to end up with is not that you're going to end up with a little pegs all over the place. Little sets of pins that are sticking up that you're supposed to put plugs down on. Okay. Now, some other boards. And I've had this show up with the ass rock H1 ten Pro bt, c plus is, I've had and I've hadn't shown up at the little card that will stick in there on top of those pins. It has a button on it, a reset button and a go button. Very nice. Not all of them. Mosul is the kind of inconsistent with that. Those are, those work really well. The other thing is, is you can buy an aftermarket little, little star button that also plugs in their song at the end of a couple of long wires and you can find those everywhere. The other thing you can do, I mean, it's kind of a pain in the butt, but it works. The tried and true method. If you don't have a button, if you don't have a button, or if you don't have a switch, is to use a knife and just put it in there and just touch those two contexts. That'll do it. Or a screwdriver. Anything metal that conducts electricity should turn that board on for you. And so I'm telling you those are three ways you can start your motherboard, but there's a, there's a fourth way to start your motherboard that we're going to we're going to do later on in the bios. I will not don't freak out because I said bio says BIO S stands for Basic inOut system, right? That's what controls the logic and the motherboard. But what we're going to do is later on, I shall I tell you these three ways to start the motherboards so that when you're doing it, if you're having trouble, you can get it rolling. But later on we're going to optimize the motherboard so that whenever the power goes off, and then the power goes on, the motherboard goes, oh, hey, look, the powers on, I guess I'll turn on automatically. But this is just one of those nuggets I want you to have in your heads so that whenever you get there you don't start screaming and stomping up and down and spitting and stuff like that. 25. Your Foundation; Your Motherboard: Let's talk about motherboards. There are many ways to do this. But I'm going to show you what I think is the most economical way, the most effective way, and the way that will give you the present for you the fewest amount of headaches. So in this case, I had to pick a motherboard. This motherboard is the gigabyte GA H11 0 dash D3, a, as you can see. And it's just your basic motherboard, except for the fact that many motherboards will only come with one PC, IEEE 16 on them, okay? And that only allows you to run one card, basically. Now, you'll see that this has the one PCE 16, and then I've got five PCI ones here. We're going to show you at some point how to hook video into those. So this motherboard will hold 123456 GPUs. Actually, as I look at it, right here, it's an M dot two slot. And you can get an adapter to put an m dot two in there that will then turn that into a PCI e. So you could actually put, if you wanted to, if you felt so inclined, you could put seven GPUs on this card, make a nice healthy. But I really like putting six is the maximum. I like putting on a rig because after six the just seems start get a squirrel and start crashing a lot. I'll tell you another motherboard. I really like the tech B15 mining motherboard. I like that motherboard. It's about and I think, I don't know, 80 bucks now, we want to make sure that this motherboard seventh, Jen, so we can work with our seventh Jin CPU, right? Because you're gonna get a C3, 930 or 4560 CPU to run and it needs to go, that's a seventh Jen chipset. And you want that to go on a seventh Jen motherboard. Okay, if you don't want to talk about Go back a lesson to when I was talking about CPUs. Alright? So that, that takes out a bunch of headaches. We know that this is now compatible. Motherboard also uses DDR for memory, so that's cheaper. I'd explained the PC IE lanes, right? For this exercise, we're only going to use one. I might do too, just to show you how. In fact I will do two, I promise you, I'll do two. That way you can see how we use multiple PCI slots on the same motherboard to have more than one GPU mining on the same motherboard that cuts down on your ROI. Okay, cool. 26. A Closer Look at Your Motherboard: So here we go. Let's, let's, let's start. This is this is our motherboard, nothing on it. We've seen it before, right? You've got the PCI slots here. We looked at the mole x points here. This is where the memory is going to go in here and this 1151 sockets up here. And for the DD R4, because that's type memory that goes in here. We're going to put that in slot number one, which is the closest to the CPU. If we look closely, we can see there's a four pin right there. That's for the figure fan. There's usually two on a board. Yeah. There's the second one right there. And that should oh, one other thing. If you don't have the first time you start up a motherboard in this upper corner. Pins in from the edge here on this bottom row, in from the edge to pins. So it'd be Pins number 34 is where you would put that socket. So I'm just going to push that on, like write that. Now, that's my, that's my pin to start this motherboard. If I don't have that, I can always. If you don't have a button or if you don't have a switch, is to use a knife and just put in there and just touch those two contexts. That'll do it. Or a screwdriver. Anything metal that conducts electricity should turn that board on for you. Sometimes you'll have problems out motherboard that just won't stay on. It keeps everytime it shuts down. Every says no matter what you do when that happens, you want to change this little coin battery right there. And it's usually a CR, 2032. And that is indeed what this one is. Ok. Let's see what else have we missed anything on this board? And let's look at the face on this you have, because this is what you would use to make a real computer is older, older style. Of course we're talking seventh, Jen, remember, your board needs to be sevenths. Jin, your chip needs to be seventh gin. And your memory on this particular board is DDR for not DDR five, not needy R6 and whatever else they happen to be up to. Now, we've got different video ports in and out. Usb ports. I've got two little dongles in here for on my mouse and my keyboard. And then your audio out here, if you are going to be turning us into a computer, and there is your CAT five connector right there. 27. Optimize Your Motherboard BIOS Settings: Okay, so we're gonna go in and we're going to check our bios. Okay. I know this one's already set up, but I want you to see how it goes. What you wanna do is whenever you start up your rig, just start tapping the F2 or the Delete button and that'll usually do it. That'll usually get you into the setup of the backend, okay? There's absolutely nothing to be worried about. We're only going to check for just a couple things. Alright, so let's start here. Miscellaneous settings, not wrong, but probably not where I want to go. None of this system, everything seems fine because the only thing I'd be checking here probably would be English. This gives the name of the board. This is a good, this is a gigabyte As the name brand, and the cart has an H, 110 dash D3 a, that's the best. Well there's gigabyte right there, that's the, that's the name. Okay, so I don't really have anything to do in system because all really would do is I would change the language to English, bios. Let's look here, C, anything we need. Very often what happens is you'll, you'll start up and the system won't work. And so you'll need to come in here and you'll go to boot option. Click on that and then hit enter on your computer and I'll ask you what you wanna do. Well, I wanted to go to my flash drive. Okay, general USB flash drive. That that's how I want this thing to start. Sometimes it will give you a stack of first, second, third, fourth options. We want to start on our USB drive. So that's, that's good. If it were disabled, I would just click on it. Hit Enter, come in, click on the USB drive in and be good. Okay. Peripherals, probably nothing there. I'm going to look Oh yeah, I'm sorry. Under peripherals, on this particular card, you're gonna see mining mode. It is either either enabled or disabled. I would imagine that you would want it enabled. It works just fine on disabled if you're only running one card, once you start stacking cards, put two or three cards on the board, it starts getting a little buggy. So you'll want to have mining mode enabled. Now we're gonna go to chipset. I like having everything in an enabled on the chipset. You could really turn off audio controller here because as just wasted, because we're not doing any audio on this board. So I'm gonna I'm a turn that off everything else. I'm just going to leave on. Now, here's the biggie. Power. What I want and what you want is if the power goes down on your computer, you wanted to come back on. So AC back, that means what do you do when the power comes back on? You can have it go. I don't know. Memory means you can have a go always on, always off. If I have it on always off in the power shuts down, the system will not come back up until I physically come back in and turn the power switch on, which I do not want to do, right? So I'm going to click on Enter again, undergo here, and I'm going to hit power always on, AC back, always on, alright. That don't want any passwords, I don't want anything else. I just want this thing to come right on. So I'll do that on a click, click and save. Save configuration reset. Yes. Now we're done. Now I will restart. And just to show you how that works, I'm going to let us start. It's going to grab Linux up here, but that's in boot on B12 is the version of Linux that we have. And this is gonna go, is going to go to the mining controller and start loading up the miner and making connections and doing all the handshake stuff that they do. And then it'll start mining EHR in just a second. You'll see it. Yeah. I've only got one card in this program. It names card number 10. So if I were to put six cards on here at number them one through five, I mean, number one and number them 0 through five instead of one through six. All right, well, we've seen all this before, so we don't need to look at this. I'm going to restart it. What I'm gonna do is I'm going to turn the power off and turn the power back on and see if the minor starts back up again. And it did because I can I can see the fans. You can't, but I can see the fans came on. Everything's working. Okay, good. All right, cool. We got that. 28. Increase Your Productivity with Risers: Risers. Now what does the riser? As we look at our motherboard, we can see that there are a whole lot of PCI slots, and now that's what our GPU ties into so that it can communicate with the motherboard and then therefore the Internet to do the actual work of mining, correct? So if we only have one GPU, we can generally put that right on the motherboard. That'll work. But what if you want to do two or three, or five, or six or four, I guess, as we've discussed, you can't fit all of those GPUs onto a motherboard. They just there's physically, well, there's just physically not enough room. Now, there are manufacturers who make riser lists, motherboards there like three feet long and 200 feet wide and you can buy them. They're a little pricey. But if you're doing it and you think it's worth fit and you'd like the ROI on it. Go ahead and do that, that's fine. They're great. It does indeed eliminate the, and I want you to pay attention to what I'm saying here. Eliminates the number one problem with a mining rig. When things are going to hell in a hand basket and you can't figure out why stuffs not working. It was work in just a minute ago and now it's not. And what's the problem that I just it's usually the riser. Risers and notorious for going bad. They're notorious for looking great and, and working one minute and sometimes they just don't work new out of the box. You'll get bad ones. You'll get some that worked for a while and then they go bad. And then you get some that are just bulletproof and never ever ever break. But generally, if you're having problems with your rig and you can't figure out why. You know, it runs fine for a day and then it starts crashing or different, different cards will run and then they won't. And then you can't tell which cars not work as a card number three or card number five. You know, if you've got six cards on a rig, remember this? It might be the riser. It might not be the card, it might not be the programming, it might not be the motherboard. It's most likely the riser. Okay. I want you to remember that nugget, okay, that'll save you hours and hours and hours of frustration. Pulley old riser off, put a new one on, see if that fixes it. Most likely your troubles will go away. Now, the risers are powered. Several ways. You can find, you can find risers that are powered by mole x. You can find them that are powered by six pin powers. But just like your GPUs can be powered by the six plus two cable, you can pop the two often, there's that six pin plug that'll drive them. Or my, my favorite is I like Santa. You can get risers that are powered by Santa. And those plug-ins, remember, no more than two ever on a saddle cable, right? So you can run to risers next to each other, off of one, off of one sadder cable. Don't run three. Also, sometimes you can find like an adapter. If you're, if you're riser has a six pin, sometimes it'll come with an adaptor that will either that the six pin will go in and it'll have a sadder female on the other end. And so you can plug them male sad it into the female satiate and the networks to that's OK. If you're having troubles with your rig and you can't figure out what the snot is going on. It's very possibly your risers. That's very often, if not most often the case in just swap it out for another one. So when you're buying, risers, don't just by one, by a couple extras. 29. Adding Additional GPUs To Your Rig: Okay. Hey, I'm a big thank you. Goes out to Mark house. Thank you, Mark for sending me those great questions. He pointed out that I was just rambling on and I never got to the point. I'll I start talking about risers like this. I never actually said that this is, this little device is how you hook up a second card to a motherboard. So what I have here is a riser, okay. And it'll come looking like, they'll come looking like this. Okay. Now I'm powering this one with Malik's. I like these because I can pair them either with mole x with a six pin or with the SATA connector. So these are, these are really great and I'm there. I had one of these go bed risers. Risers are usually your problem if something's wrong, check your risers first. So what we're gonna do is I'm going to take the USB port it in here. So now I've got power coming in. I've got data going in and out. And so what I'm gonna do is this is this little adapter, PCIe x1 adapter. Plug the USB port into there, and then I'll go into one of the PCIe x1 video ports, right? Because you know the 16 as well here when cooled off, the 16, PCIe 16 looks like that, right? So the bottom of the graphics card is going to punch into there. But I've only got one of those on this board. I've got a 16 and 3. Number one's PCIe 16 and ones. So they're now that's on there. I got power. It's got the data running through the motherboard. So what I do now is I take a riser, my assemble it, I put power to it. And they take this part and this little adapter. And I slide that little adapter into one of the PCIe ones. Okay, now I'm going to take my second GPU card. I'm gonna take that second GPU card. And you can see here, this is an x of x RX 570, four gigabyte. This isn't a gigabyte, so you can mix 46 gigabytes on the same card or the same rig, no problem. You run into problems when you start and that'll be the next question I answered. When you start mixing architectures like Polaris or AMD and NVIDIA. Okay? So I've got my second card. I'm going to pull up my riser and you see how that's now got a PCIe 16 slot on it, on the slide that into that PCIe 16. Now this still is not going to run because I've got to put power in here. So I'm going to take my six plus two that we saw in a previous video. I'm going to push those together. So now I have an eight pin because this card demands an eight pin plug. So I'm going to push that into the power right there. I'm going to make sure that clicks down. So I've got my my riser on the bottom. I've got my power in here. I've got my data coming out through the riser, and I've got my power coming in on a mole x. So now I'm going to hit this and both of these, you should see the fans on both of these GPUs startup and they did. Okay. Now for giggles, you can see over here now, since I've plugged the HDMI into one of my cards, there'll be starting up and we'll see on here that we've got two cards now, instead of just one carbon had earlier. Now I'm mining Raven caught on this rig. So it's hard to tell but one is called clc and was called C L1. If you're, if you're mining Raven point, it looks different than if you're writing a theorem. 30. Save Your Gear with Thermal Paste: Thermal paste. Now, there's kind of an interesting thing is it's kind of, I don't know, it's like real thin putting or toothpaste, real thin toothpaste that comes in a little tube, sometimes a little tub with little spatula, or sometimes like a hypodermic. One of those things. And that's actually what I prefer. Now, what thermal paste does it transfers when you have two surfaces that touch and ones really hot and you tried to dissipate the heat across to the other surface. Sometimes they'll surfaces don't match perfectly thermal paste in between the two, we'll move that heat from the hot surface into the cold surface. So if you have a fan array or fins or even a water-based cooling system, you'll want to put thermal paste between, like most traditionally, it's your chipset, your, your, your CPU, and the cooling fan that it comes through. Now if you take apart, you can take apart your GPUs. You can take this thing apart. And there are half a dozen or more chips inside there that you may want to read paste. So what you would want to do is take off all the old pace because it gets hard, it gets brittle, it becomes ineffective. So soft to medium toothbrush, you get in there, you scrape those often you, you shine them up and then you put like a p, small p, large p depending upon how much of the surface you're trying to cover, because they've got a big chip in there too and have lots, a little small chips to so you put just a dollop of thermal paste on those. Not too much. You're not trying to paste this thing together. It's held together with screws, not thermal paste, but you want that thermal transfer of the heat to make the cards run because a card and your CPU that is cool. We'll run longer, we'll wrap, will, will run longer, will run more efficiently and produce better results. So you can do whatever thermal paste you like. My personal favorite are the ones that come in hypodermic. Because I can just, I just leave that on my workbench and I've got a quart jar, I've got screwdrivers and pencils, and I've got a couple of hypos of thermal paste in there, pull him out and just like the size of a pea, pop, pop, pop. And then he put it very often solved your problem. But you absolutely want that when you put your, your fan on your CPU, absolutely have to have it. Now a lot of fans come with a dryer type of thermal paste already applied. Don't touch that because the oil on your skin and that thermal paste don't get along right. It doesn't work well. And that Greece in your finger can cause the oils in your fingers can cause damage to your systems. So don't touch. But make sure that you've got clean dry surfaces. Break off any old thermal paste that happens to be there. I like using a toothbrush, put on about the size of a pea, put it all back together and you should be, you should be golden. 31. Keep Your Gear Cool with Cooling Fans: I want to talk for just a moment about cooling fans and I'm not talking about the the the fans that go on the outside of your rig or I have stand up fans in my in my barn where I have my mining rigs because it gets really hot in there. And so I've got your standard oscillating or box fans all over the place cooling stuff down, augmenting the the standard cooling that happens on a on a on a rig. But when I'm when I'm specifically talking about now is the little fan that goes on top of the CPU. They'll, they'll come, you can't just plug a CPU central processing unit into a motherboard and turn it on and let it run for very long. Because what's going to happen is that CPU, the brain of the computer gets so incredibly hot, it will burn itself up, just absolutely melt down. Okay? So what you have to do is you put a special fan on top of it. That special fan attaches to the motherboard and has a flat space that lays on top of the CPU. It's like a heat sink, right? So the CPU gets really, really hot and you're putting on these fans like a radiator that touches against the CPU and dissipates the heat. The CPU gets hot. The heat is transferred into the fan or the cooling unit that you have. Some people cool with water. Some people cool with just standard air moving fans. I like the air moving fans. Water's really messy. Some people will even submerge their GPUs in mineral oil. That's an interesting thing, really messy. And it gets really bad for all people in all things involved. And I think that practice has pretty much been abandoned. Except by the, except by all but the geeky jist of the geeks. So we're just talking air cooled fans. Now, that surface between the CPU and the cooling fan, you're looking at metal to metal. It doesn't really work because, you know, they're microscopic areas of space in there that don't work. So you had to put just a drop about the size of a large p, thermal paste in there. The thermal paste transfers the heat from the CPU up into the fan. The fan body will snap onto the motherboard. There'll be four holes around the area where the motherboard with a CPUs sits on the motherboard, there'll be four holes. And then on the bottom of your fan unit there'll be four little pegs that go through those four holes. And then there will be some sort of snapping device or expanding device or something. So you can lock that fan on because it has to press hard against the CPU so that all that heat will transfer out. And then there's a fan on that array of fins that dissipates the heat or sucks the heat away from the CPU. And blows it out into the room. Now, you can go hog wild on that. The ones that come stock with, especially the CPUs that I'm going to suggest to you that the fans that come stock are absolutely adequate. Absolutely. Just fine. You can go, like I said, hog wild and get some really interesting fans that do the same thing. There are some fans that are almost a 100% quiet. Some really amazing fan technology out there. But what I really like is I like, and I know it seems silly. The RGB red, green, blue, the LEDs on the fans. And I'll tell you why. I've got several rigs. Maybe I'll show you pictures on. But they're out in my barn and it's fairly well that area. But sometimes I'm working on them and I'm turning them on and off by via the computer controls. And I'm turning in, I'm troubleshooting if because maintenance. Right. So if I have I have some rigs that have no lights on them at all. So if I start it, if I stop it and then start it, I have to lazy asked me right, I had to get up. I have to walk over and look at the machine and see if it started or not. Now if I'm in the barn, that's not a problem. But if I'm in the house or if I'm in on doubtless or St. Louis or on the beach in Florida. And I'm trying to do that. It's a little hard to get up off the beach of Florida drive all the way back to my house, which is a long ways away from Florida and see if the machines started or not. When I'm there in the barn. It just it adds speed. If I have an an RGB fan. So remember decorative some flashlights and stuff. I like having something on that rig that has some light to it. So when it turns on, I see the lights come on. When it turns off, I see the lights go off that way. I'm not always going over and just look and say is that fan does that fans spinning or not? Okay. You know, especially if they're in the dark because I've got all my rigs on racks and racks are pushed back up against the wall and okay. I can certainly see the top two shelves, but what about the bottom two shelves, right? So anyway, so that's what I like about that. The other thing is for modern motherboards, you're going to want for pin connectors. And that's a very small four pin all in a row, and they connect to the motherboard. If we look closely, we can see there is a fourt pin right there. That's for the best for your fan. There's usually two on a board. Yeah, there's the second one right there. You can also get cooling fans that have three pins. And they tend to work as well because what happens is just leave one pin off, but the three pin plug will still fit into the four pinhole. Sometimes. Not always. So just if you have your choice to buy a three pin or four pin by a four pin. That way, if it's four pin, it will have a modern footprint and it will snap onto your motherboard without any difficulty. 32. Keep Your Gear Together in a Frame: Let's talk I've been talking about mining rig. What do I mean by that? Well, I mean, this whole construct that you and I are making, we got a power supply, we've got a motherboard, We've got a GPU, got cables going everywhere. We've got the USB card sticking in. And now you're going to put a power plugged to the wall. You're going to have an internet cable coming in and sticking in the front and Ethernet car. Like a cat five, a CAT six or seven cable going in the front so that you can attach to the internet. You're also going to very possibly have an HDMI cable coming in so that you can plug into a monitor so you can see what the the the the rig is doing in real time. Okay? It sees one GPU labeled 0. So 0 GPU tells the speeds of stuff. Alright? So it says starting to grab jobs. But the thing is, is you've got all this stuff and I'll show you, you're probably looking at it right now. I'll show you a picture of what I call my test bench. This is where I run one card at a time. And it's a mining R3. I leave it running like just like this. I is not in a rig. It's not in a frame, it's not orderly. I have the motherboard sitting on a cardboard box because my table underneath it produces a lot of plastic or nylon. And that table produces some static electricity. So I don't want that jumping over my motherboard. So I have my motherboards sitting on a cardboard box. I just have the GPU sitting on the table or on the board, depending on if I'm running one or two GPUs and I have the power supply sitting on the back. When I first started, what I did is I had those open air wireframe shelves and I put my power supplies on the shelf there, real heavy that made the thing stable. Then I put down a layer of cardboard much like this box and put my motherboard on top of it. And then what I did is I would zip ties, hung the GPUs around the motherboards so that they got a lot of air and they were cool. Okay. That's when I only had like one or two rigs. Then pretty soon I discovered that becomes real unruly really quickly. It's an awful way to do it works if you've only got one rig and you don't mind the ice or that it is. But putting putting all of your gear onto a actual mining frame, an excellent way to, to order it to, to, to, to, to get some order out of chaos. Plus is also now if I need to pick up a rig, I can pick up the hole, I can unplug it from the wall, pick the whole thing up and do the cables, pick it up, Cyril, my workbench funding to do that. So it looks good. It works good. And it actually is a real safety feature. Before I would I need to reach in there and grab that. I'd stick my elbow in or something and I've hidden GPU fan and break a fan off the fans and that's awful. They're for sale. You can buy a rig if you want to. A mining rig frame, they're fairly inexpensive. You can find them all over the place. The other thing you can do is build yours what I've done and maybe I can include the numbers on this, but what I've done is I just get two-by-twos, which is a piece of wood cut. In theory two inches by two inches, but they're shaved down little bit. I think we'd like 13 quarter, so I wanted to be quarters, but I just buy a couple of three eight-foot pieces of two-by-two and I get the saw out and the drill gun and US screwdriver and and I make my own place. Thanks. And that works for me. So it's up to you entirely. Like I said, I'm just showing you how to build the first one and get it running. That's the whole purpose of this lesson. And you can do your own design aesthetics later. But putting things on a rig, on a frame is a real good safety feature at it protects your equipment, it's orderly and you'll be happier with it. 33. Know Your True Electrical Use with a Voltage Meter: One thing you might want, and now in the way of tools, and this is completely optional. It's a utility, it's a voltage monitor. It's a handheld item, like plugged into the wall and then you plug your device into that. And it gives you a reading of what your actual power usage at the wall is. Now, your GPU's will say that they use x amount of power. You're motherboard will say that it uses x amount of power. Your CPU will say all that, you know, everything will give you. If you do the research, you'll be able to find the, the traditional excepted amount of power usage. Part of maximizing your ROI is getting the most hashrate out of your rig, but also minimizing the amount of electricity use. But this is absolutely optional. I use a kilowatt. There are many brands of this handheld device that you can put on the wall and that allows you then to fine tune the amount of power you're using and to know the amount of power you're using. But if you're just doing 11 card to start with, nice to have not necessary. I'm probably even a luxury at this point. But once you get up to like six cards are eight cards and you're trying to figure out if you're being safe or not. This is a great tool for knowing if you're safe with your electrical usage. I just thought I'd mentioned that you don't need to rush right out and buy one. But it's a nice, it's nice to know they exist. 34. Building Your Crypto Miner: Looking at this, what I'm gonna do is I'm going to get my CPU. This is the central processing unit. This is a seller on 3930. You can probably read that right there on the front. This is a really small, not real powerful chip, but it doesn't have to be for mining. Now, I want you to see a couple of things here. Notice I'm not touching the back. Don't don't touch the back. And a definitely don't touch any pins inside of here. We'll look at that in just a minute. But if you look at this chip, I mean is that square? It can only go in one way if you try and put it in any other way, it's going to damage your motherboard. So if we look up here, we see a couple of tails right there. There's a little notch. I don't know if you can see that little notch there in a little notch there. So we're gonna look in the socket. When we open a socket up, we're going to look for those two notches. Those, those little ears are going to go into those little notches also right here. And this is mainly what you should look for, is there's a little arrow printed in one corner. You see the other corners don't have that little arrow. One's got a little dot or something on it. They all have dots. But only this one has an arrow, so the arrow is pointing down and to the left. If we look at our motherboard, the cover right here that's protecting the socket, has a down and left arrow, right here. Okay. But just in case you have a motherboard that doesn't have this protective socket or that protective layer on the socket protective cover down on left. And then it will also be most likely printed on your motherboard or in Boston to the socket right there. But there we go. So you see the little arrow there. You see the little arrow there. Now we look up in here and we can see There's a little ear there and a little ear right there. And those are going to go into those two little slots that we saw right there. Okay. Very, very gently. Now, what we have here is like, I don't know, five or 600 maybe little pins that stick up and they make contact on the back with these contexts that may all look like a solid brass, but it's not. If we get closer you can see it's just an array of pins. And those touch these pins that he had to be very, very delicate and very careful. So I'm just going to come in here and I'm going to lay let me see if I can do this so that you can see it. I'm gonna come in here and I'm going to lay my CPU right in that slot, just like that. All right, now you can flip that lead down. There's a post right here that these two little lips are gonna go under. And then take this and push it forward, pulled out and slide it under the end. Like just like that. Often this will pop off like it did just like that. Okay. So now this is, this is in here solid. It's locked in, is in the exact right place. Now we need the thermal paste. Heat sink pays heat sink, compound, thermal paste, whatever it comes in, it comes in gray. I think I've seen it once and blue doesn't matter. I'm just gonna screw the top off right here. And in the middle of this chip, I'm going to put a fairly large pea sized blob. There might even be a little bit much. Then I'm gonna make sure it's right there in the middle then, just because I'm obsessive compulsive, I'm gonna put just a little micro dots, just a little bit. You don't want this to be too messy, but you weren't to be you want full coverage. Now that might have been that order. Probably what I should have done is put this on next. This is the ring that holds the fan on. The type of fan that I have is, is like this. Now you see this surface. It's going to mate to this surface so that when this CPU gets hot, this block gets hot and this block has fins on it and a fan that will then cool it down. So this acts like the radiator in your car. Okay? So I need to put the base down for this because this doesn't have any way to latch on. So I need to put the base down. So give me just a second to make that happen. You'll see it's got little expander holes here and these go inside of these slots on here. And then that little pin goes through one of these four holes here, here, here, and here. That's what holds the frame down because you put this little pans gonna go in inside of the other frame. And a peg goes in here and expands the back of it out. And expands. A little pin comes through and expands the back out so that it holds onto the motherboard. Okay, so wanna push this back through so I can do it correctly. Here we are. I've got my got my four pins. So I'm gonna make sure that these go into those holes. There we go. So those for-loop, most for little connectors are now sticking out of the back 1234 and holding this frame on. Now I want to walk those in place. So I'm taking a little locks and pushing those through as well. Now each, each MT is going to be just slightly different. But it's all intuitive and you can look at it near your bright guy. I mean, you're in figured out without much difficulty. They just go in and they pop in. And once you get the little peg pushed through the expander, it's locked on the board and it won't come off. Okay. So that's on there. That's on there. I've got those four pins in there. You can see how there's the little white thing that expands. I push the pin through and it pushes it open and locks it into place. Alright, so good. We've got that we've got that all done without me smearing the thermal paste that I put on prematurely. Okay, now, I'm gonna make sure this mates directly down. Now, this has little ears that have little spring loaded. This has little ears that have little spring-loaded latches. So I'm going to want to hook those onto the latches here on the side of this frame. And you know, this is nothing to it, but do it. So I'll put in one down, snap it into place. That I'm gonna spend the board just a little bit so I can get over this other one and push it down and hold it in place. I can feel that GU, I can fill that paste moving around and they're going to give it just a little bit of a wiggle so that it makes really well pop that in. Now that fan is on, that fan is on there. Ok. So now take your little, your little power lead and you can either put it into this power spot or what's the other one, or the one over here. I think I'm going to put this over here because it's a little more out of the way. Now this is an excellent opportunity. This fan came with three holes and is supposed to be a four pin fan, but a three pin hold, a three pin fan will work on a fourt pin because they just left off the one pin that doesn't have anything going through it. So it lines up anyway. So good engineering that okay, so there, alright, now the fan is on there. Now we're gonna take our four gig DDR for memory. A memory stick here. Not, not fancy, not pretty, just, just utilitarian. And we're going to go into slot memory, slot number one back here. Okay? And we're going to make sure that this little notch, that little notch here is going to line up with this notch here. Alright? And this is going to go into slot number one. So let's do that, making sure that this notch and that notch line up. Just take it and slide it into Lawton Rock, put it in slot number one and push it down until it solidly in there and it clicks in place. He this little lock here will snap down and make sure that that law, that lock will articulate back and forth. So make sure that it's out. And then when you push it in, it'll snap and hold it in place. So now we have the memory on. We have the CPU or central processing unit is under there. We put that pit that we put that chip in. We locked that down with the bracket and the cooling fan system on. So we're good with that. All right. Now let's start hooking up the cables. 35. Putting Your Rig to Work: The Start-Up: All right. Let's take a look at this stuff, Shelly. Let's start out with the power supply for this is a modular unit. As you remember, I was telling you, modular unit has no Noah cables attached to it. You can, you can set it up however you want. Now, this particular this Coursera RM, a lot of times people turn them on and there'll be unhappy because I'll say it's not working, it's not working. The fan will not come on until the machine gets hot. So it can be supplying power, but it's just the fans not spinning on and there's no light on this to say, okay, It's on. So be aware that if you happen to buy a Corsair, alright, so let's look at set this aside. Let's plug these injustice, just the sialic or moving out and do one at a time, starting with the big kahuna. So here we go, here's our power supply. This side is going to go into the motherboard. And they've always got to latch on them. So you'll you'll always be mindful of where that little latches. Okay. These two also have latches on. So and if we look closely at the power supply, you'll see there's a plug and then a hole on the top for the latch, right? So that's what we're gonna do here. We're going to plug these in. And as Sammy Hagar, and it's not rocket science, right? This just as just plugging it in. So yeah, there we go. It's somebody's wires are really stiff. But, you know, it's just, it's just what it is, just what it is. They aren't made to be moved around a lot, pushed out over there, and then I'm going to find my business from my CPU. Yeah, put my CPU and here. So it's got eight plugs on land. I'm just kinda find because I've got the 24 here, I've got a bunch of sixes on this end, and these are all eight pins, so I need an eight pin going to plug that into the eight pin. Very good. Then of course my Malik's, there's my mole x and this is six pin. So I'm just going to plug that up here on the top. It doesn't matter. It does not matter where you plug anything except for the 24 pin will only go into one spot. The eight pedal go anywhere and that's fine. So there's the six, there's my mole x and now I have my, my board taking care of my, my, I've got the three chords. Take the tower board, the one to parallel motherboard, wanted power the CPU and one to power them Rolex. The mole x is actually not necessary when you're only running one card or two cards usually. But when you start getting into 345 cards, sometimes the, the, your motherboard will protest in crash. So while we have here, now we have the the six plus 2s that I'm going to use for powering the GPUs, right? So I'm gonna find the eight pin end, plugged the eight pin into your power supply, not the six plus two. So I'll plug that in here. And then I only have one cable left. And that is my Santa. And then that's going to be six. I'm just unplug it over here on this side as well. Alright. So now my friends, this has all plugged in, this is ready to go. Of course, you're going to need this to power the power unit. We always going to want to do is want to turn it off when you're working with it to to before you start powering anything and upper plugging things in, her life. Turned off. So I've just turned it off. I'm going to plug this in. Right. Now, that power supply is ready to go. Now, I'm going to, is, it's off. I'm going to push it over here a little bit at the one. I'm gonna get my box and put right here. And you'll see why I need a box to build on in just a second. You don't always need a box. You can put it on wooden blocks or what have you try them up, put on anything that conducts electricity, or it has a lot of static in it. So now let's start hooking up the cables. Is take the 24 pin, push that in first. Right. Make it make sure it goes in snugly. Makes sure it snaps with the latch. And you want to treat your motherboards nicely. Don't be bending on, don't be putting weight on them, you know, support on when you push stuff in the eight to eight pin for the power supply for the CPU, and sometimes that'll be a four pins. You remember, we talked about that. A lot of Coursera plugs, they'll write on it what sometimes when it does the CPU has a special cable and will market for CPU, ok, you don't want to use this cables or drive a, a graphics card because the wiring might not be right and it could damage all sorts of things. So I'm gonna take this now and plug that into right here. We saw that already, right? So that's the CPU power, the motherboard power. Just because I've gotten this right here, I'm going to put the mole exon because I am going to put two cards on this time. The mole x is going to have to square points and two rounded points on the plug. So be mindful of that. They're goes in that way. And then I've got the other mole x. And I'm going to put it in on the other end of the board like that. That's the CPU power, the motherboard power, and the mole x power. The board is taken care of. I've got the key and put the key in. No, no, will do the key last. And I put my first, my first GPU. And here, you know that over the edge so that the little teeth have a place to hang off of. We said until you hear it click and it's in there, nice and solid. You don't want any of those bras, tabs showing on the bottom or copper tabs. Then I'm gonna find a six plus two. And I'm gonna put that inside of my power plug right here. Alright? And at the moment I don't need Santa because I only have one GPU on here and that GPU has plugged into the CIE 16. As soon as I go into a PCI y_1, I'm gonna need that Santa. So let's start this up, make sure orcs, and we go. Well, the fans started spinning and oh, you know what, I didn't do. I did not hook it up to the internet, which is excellent because that will get to show you an error sign that you will, you'll sometimes see and go, what the heck is wrong. Why am I getting this error phone? Well, the first area is I don't have nothing's happening is because I don't have a key put into it. So I'll put in a key. We turned it off. I, I'm always averse to plotting stuff and so, so I'm going to, so I'm going to put the key in the USB port, turn them on. Now, I purposely did not hook up the internet because I want you to see the error message that I'm going to get. If you start getting this line of just short bits of code with an okay, and nothing seems to happen after that. Unless it just keeps recycling it. Problem is you didn't plug in your internet or it's not, the Ethernet is not all the way in. So I'm going to, I'm just going to push that in right now and you'll see it change. There we go. Okay, I got a message or sit waiting for all GPUs. So something's happening. It's gone through us checks, is looking at us, looking, okay, it sees one GPU labeled at 0. And it's not scary. It's just code. And as you look at it, you'll be able to see that this is saying GPUs 0 because they start at 0 instead of one. Sometimes GPUs 0 is working under these parameters. A core clock 01150, the memory clock at 2100, and under bolting it 900, okay, and a power stage of four. This says that it's looking at is detected as found a working GPU. This is just giving you an instructions on what's going to happen as talks about the difficulty of mining and what the difficulty rate is today. Tells you what Poole you're involved in right here. If you're mining to a pool and I am ok. So now when we get to the blue here is saying the mining ethos. That's what we wanna do with one GPU worker, ok. Now you will see most of this is all just the, the computer keeping track of the work it's doing so you can ignore the stuff in white. The stuff that's colored is the stuff that matters to us. As we look at this, we can see right here, you'll see a colon 0 and our colon 0. And then there's LW or HW on this one, which means nothing. But what it does is this is when you're mining, you, you grab shares. So you grab groups that have you do successful mining. And when you do that and you find a part of the solution to the problem, you get a share. Okay? So as we look, I mean, I just plugged this in so, you know, but if we look, you'll see a Fermions accepted 0 shares and R, which means rejected means 0 shares. Okay? And also we have LW, which I don't know what it means on this program, but usually that means it's an orphan share, meaning you are working on it with somebody else solved at first. So too bad you're Abdullah. The rest of this is just the pool timing itself, seeing how fast it takes to get a job and then do the job, and then get the job and do the job and give a job to do the job. None of that matters to you. I'm I'm just hoping that what we'll see here is I'm going to leave this camera run for just a second. See if I've only got a minute or two left. Let's see if we can get to see if we can find a shared here in just a second. Let's turn it off the list. But a second GPU on this. 36. Secret Agent Code: Now, when the minor has started up and it's running, and if you've got plugged into a monitor with the HDMI cable right here. It looked right there at the bottom, is because it's going to be clicking. It'll say a screen is terminating minor stat worker 0, 1, and then they just sit there and do nothing, right? Your screen is really not doing a whole lot of anything except telling you that it's, it's kinda go on. Now, if you will, type in the word agents, that screams doing nothing, see how a static, we want to turn that dynamic. We want to see what, we want to see that this miners doing moment by moment.
