About This Class

This is a class about the joy of Circuit Bending.

In this class, we will first talk about what Circuit Bending is, and how it works. Then, we will actually circuit bend an old keyboard from beginning to end, going step-by-step through the entire process. In the end, we will have a cool new keyboard capable of brand new sounds, and I'll even make a track with it.

This might just be the weirdest class I've ever made. In this class we will hit the road, going to some thrift shops to look for bendable instruments, I'll do some time-lapse videos of taking things apart (complete with Benny Hill), and we will melt down some Spongebob Squarepants. You will have to join the class to see how that all unfolds.

You will not have another opportunity to learn Circuit Bending in a more comprehensive way than this. Start here.

Praise for other classes by J. Anthony Allen:

  • "I've had Live Lite for a while but never quite understood how to use it because of the different options in how to arrange audio. This course explains exactly how to do that and get the most out of Live."
  • "Great overview - I would start here for sure if you are just getting your feet wet with Live. clear and to the point. session walkthroughs are great. looking forward to more"

  • "I have never had any formal training in music at all. Trying to learn all the notes and how everything translated was a serious challenge. After going through this class, Dr. J has totally brought down the barriers. The content was very useful and was easy to grasp for me."

1. 1 Intro v2: okay. Circumventing has a long history, and there's actually some really interesting books on it is going to be attached, so we're going to kind of gently move it aside. First story went to I'm now in the game section. Sometimes these games could be really fun. Confined cool stuff like this is where you might find, like, speaking spells, which are probably the lot of the time. What I'm looking for is a group of stuff, like, I think there's good stuff here. So that means that if you do something wrong, no, let me preface this by saying this is unlikely. Hey, everyone. So, uh, in this class, we're gonna be talking about circuit bending. So if you don't know what circumventing is, basically what that means is we're going to take something that already exists. We're gonna some kind of electronic sound making thing. We're gonna open it up, we're gonna connect some extra wires that's going to give us a couple extra switches and knobs, and we're gonna make that thing make crazy sounds that it was not intended to make. And with that, we're gonna do some really cool musical stuff with it. Um, so throughout this course, I am going to circuit Ben something. Um, I'm gonna start off by showing you my big circuit bending project. My big keyboard, which is this one on this keyboard. I have about 100 bends. There's about 50 switches here that I've added about 50 switches here that I've added. All of those extra switches create tons of extra sounds. Not in the keyboard. So I've opened it up. I've added all kinds of stuff, and then I put it back together, adding, all those switches. Now, what we're going to do in this class is going to be a slightly smaller scale. What we're gonna do is I'm gonna take this sponge Bob Square pants keyboard, and I'm going to add these four switches. Now, as you might be able to tell, Ah, I always film this intro lecture after I've done the whole course. So when we start the course, these switches air not going to be here. Ah, they're going to be added later. Um, throughout the course, we're gonna open this thing up. We're gonna connect some wires, and we're gonna add these switches that are going to make really cool sounds out of our sponge bob Square pants keyboard. So I bought this at a thrift store for a couple of dollars. 3 99 to be exact. I'm gonna walk you through that. I'm actually gonna take the camera into the thrift store, and ah, covertly filmed myself shopping so I could tell you what kind of thing to get. Um, I'm gonna do all of that in this course, So we're gonna go from beginning to end from selecting something to circuit bend every step of the way to ending up with the finished product. And then at the very end, I'm actually gonna make a track using this thing. And it's the track you're hearing right now. Um, that track is composed 100% on this keyboard. My sponge bob Square pants keyboard after some slight modifications. So if circuit bending freaks you out, it doesn't need to. It's actually really simple. I was shocked at how easy it is once you know a couple basic principles about doing it. Um, it doesn't take any knowledge of how electricity works, how it struck a tree works anything. It's really all about experimenting, so we're gonna open it up and then we're going to start experimenting, and I'm gonna show you exactly how to do that. So I hope you join us in the class. That's gonna be super fund. Uh, we go from having nothing to ending up with this cool keyboard. And if you follow along with every class, you will end up with this really cool circuit bent toy of your own eso. Let's jump in, Let's jump into the course and get started right away with our first basic things that we need to know I'll see you inside. 2. 2 WhatIsCircuitBending: Okay, let's get started. So what is circuit bending? So, first of all, um, I've probably said this in the intro, and I'm probably going to say it again several times. It's not as complicated as you think, if you know what circumventing is. Ah, relax, because when I learned how to do this, I thought I was in for, like, a math class in engineering class. But it's actually super easy and kind of scary. Easy, because basically, what we're gonna do is guess we're going to do a lot of guesswork. So what circuit bending is is you take something that makes sound some kind of sound making device that's designed to make sounds in a certain way, and then you open it up. You look at the circuit board and you'll, uh, make changes to it so that it makes sounds that it was not intended to make a lot of the famous circuit benders. Look at this as treating the circuit board like a canvas, which I think is really a beautiful idea where you got this circuit board and it exists in one way. It's almost like a found object, but it can be changed and twisted and bent, if you will, to make it something different, right? So that's what circuit bending is. So basically, what we're gonna do is we're gonna get something on, and we're gonna open it up, and then I'm gonna tell you what to look for, what to find so that we can make some new connections inside there that will change the way it makes sound. Now, uh, we're gonna be going through how all of this works. There's obviously some safety things that consider because we're working with electricity. We're gonna get to that in just a minute. So don't start taking apart your stuff. Uh, quite yet. Uh, wait until I tell you what to do and then go crazy. Start taking apart everything you confined. Circumventing has a long history, and there's actually some really interesting books on it. I encourage you to check those out. I thought here in this first video, it also show you one of my most successful bent keyboards where I took apart a keyboard and , uh, added about 100 switches on it. And I'm going to show you that in just a second before I do that. Let me just warn you that, um, the best way to start off doing this It was something much more simple than a keyboard. And we'll talk about that soon. I'm gonna take you on a little shopping trip where I find some good bendable stuff in just a couple of minutes. But now let me show you. Ah, my favorite circuit button keyboard and jam out on it for a few minutes. Okay, Sorry for the shaky camera here, but I don't have a good stand for this keyboard. So I have here in my Yamaha ps are 200 sufficiently bent. So you can see this is this is a normal keyboard that, you know, it's a Yamaha keyboard. It's nothing really fancy. Um, this was actually my girlfriends that she had to learn to play piano when she was a kid on . It's just kind of been following her around for a long time. So I thought, Hey, let's make something cool with it so you can see the modifications I did over here. There used to be a speaker over here, and I've replaced it with 12345 612345 so 30 switches here on different strick. It's so these. Each one of these is a switch that flips in new circuit on over here where the other speaker was have about 31 2345 23 45 25 knobs, This one I've already broken off. And but these knobs, I've added where those speakers used to be, Um, so it makes some pretty crazy sounds. Now I turn on some of the drum pattern still just a tempo on and I could just start flipping switches. That one gives me a bad accent in snare drum. - Not all switches and knobs work all the time. Like, right now I'm listening to this drum path and it doesn't really like some of the switches. And some of the knobs are only going to affect sounds that are not the drum sounds or the keyboard sounds. So a lot of what I'm screwing around with the keyboard sound, and I can call it more of the presets if I remember how. Um let's see. So there, listen up here to dance. This is type in a random number. There we go. You can see I also screwed up the display. Now with a by product. Turn off, Trump over here. I like that. - Awesome . So that is my Yamaha PSR 200 with about 100 different bends in it. 3. 3 WhatIsBendable: okay, Lets quick talk about what is bendable. Like I said before, I showed you that keyboard, Um, that that big keyboard that I just used is obviously bendable, but, um ah, trickier than most. So there's a couple key things that we're gonna be looking for when we look for something to circuit bent. Um, the 1st 1 is that it has to absolutely has to be able to run on batteries. Um, it's got to be battery power now. It can be battery powered and plug into the wall, Um, depending on what you're using it for, but it can't be something that needs to be plugged into the wall. Ah, that is just way too dangerous for us. And we're gonna talk more about why. Ah, that is the case when we get into talking about the safety stuff, but it has to be able to run on batteries. That's rule number one. Rule number two is that it has to make sound. Um, you can't circuit Ben something to make cool sounds. That doesn't already make sounds. Um, there's maybe a way to do it, but it was It's wave too complicated for me, so it's got to make sounds already. Um, I have seen you know, you can circuit Ben things like, um, like I've seen people do stuff with, like, game controllers where they circuit bend them so that, you know, when they push like the fire button on on their Xbox controller, it actually, like, rapidly hits it like, a 1,000,000 times. Um, that could be possible, but I don't really know how to do that. So and I'm talking about music stuff here sound how to make cool sounds. So it's got to make sound to begin with. The next thing is that avoid stuff that looks like it's basically a little computer. Um, things like your I phoned, you know, like, yes, it makes sounds, but it's a whole computer in there, and you don't want to get in there. Um, in particular, Apple products are essentially unbending ble because they're so ah, closed in and and tight. You would need you need robots to get in there to do stuff. You can't really work inside of those things with your fingers. Very well to do what we need to do. Um, so avoid things that look like there's a computer inside of them, um, things with, uh, touch screens and stuff like that is just gonna be way too complicated. Um, and a lot of the sounds are held in the microcontroller or the circuit board while the microcontroller Let's just call it, um and those are very hard to get at, so we don't want computers. Computers are very difficult to work with in the last thing kind of jumping off of that that I was look for is it's gotta have a circuit board that we can get our hands on. We don't want something really tiny. Um, I saw today when I was looking around for stuff to bend this like plastic toy machete that , like when you swing it, it made a sound on. I thought I could be kind of cool because it's a toy. It makes sound. Um, that's great. I could circuit been that to make some crazy sounds when you swing it. But the thing the circuit board was gonna be, like, the size of my thumbnail, and I wasn't gonna be able to get in there with my hands with the sauntering iron and poke around. It would be really difficult so I passed on that one. Um, the things that we look for tend to be ah, toys. Toys are great. Um, kids. Toys that make little goofy sounds are fun to circuit bed because there's a lot of stuff to do on him. Um, also, people are really into circuit bending like effects pedals and stuff like that. It's not too hard. Um, and there's a lot inside of those things. They can be a little small to work on, but not too bad. So those are also popular. Um, so those are the things that look for when we're looking at a toy. So or when we're looking for something to circuit bend. So, uh, we're gonna do one more video than after that. I'm going to pick out. I'm gonna go shopping and pick out something. Ah, that you can see that I'm gonna be working on throughout this whole class. So, uh, let's move on and talking about the tools we're gonna need Ah, and then we'll go shopping 4. 4 ToolsWeNeed v2: Okay. The tools we're gonna need. Not a lot of tools. This is not a very expensive thing to do. Ah, but the main tool we're gonna need that you may need to go out. And purchase is a sauntering iron and some sauder now a soldering iron. You can get a cheap one for a couple bucks. You can get a fancy one. Ah, you don't need a fancy one. Um, cheap one is Just find it needs to get real hot. Um, and that's about it. So get yourself with sauntering iron. You're gonna need that when we go down the road. Um, you're gonna need some sauder. That's like this little metal wire that we basically melt onto the board to make a connection. Um, I'll talk to you about how to use those things when we get there. Now, just just if you're like me, you're gonna get a soldering iron, and you're gonna plug it in and fire it up to see what it does. Be careful with that thing. It gets hot. Um, it will burn you a lot. So, um, but pick up soldering iron. Um, sauder wire. You're gonna need some wire we don't need to be really specific about what kind of wire? Um, just some kind of thin fish wire, not thick wire. Not like a coat hanger, but like thin wire, the different gauges don't really matter. It's got to conduct electricity. Um, the thinner, the better to a point. Um, we tend O. R. I tend to like wire that will hold its shape so you can bend it into a shape, and then it will stay there. That's good for when we're testing stuff, because we can basically make a jumper cable, bend it in a certain way, and then just stick it on stuff and then to keep doing that s so get a little spindle of wire. You don't need a ton of it, but Well, depending on how maney switches and knobs you're gonna add to your thing, you might need a lot of it, But, um, get a role of that, Um, and it's also good to get two rolls of it in two different colors. Get like a red one in a black one. Um, or something like that, because it will help us keep track of what we're doing. A little bit. Um, some screwdrivers we're gonna need when we start taking stuff apart and putting it back together. And duct tape is always good to have around. I can't actually think of a specific need for duct tape, but, um, something inside me says you're gonna need duct tape. So get some duct tape, Uh, or just some really strong tape. I think that's it. Batteries, batteries for your whatever you're gonna bend. So because it's got a run on batteries, so you're gonna need some batteries. You might need a couple so that you can burn them out and then do it again because we have to kind of leave it running for a while while we do a lot of testing. So ah, but that's it. So soldering iron sauder wire. Ah, Oh, ah! Wire Stripper. You can get these little It's like a a pair of pliers that will quickly and easily strip wire. You could also just use a knife to strip wire to, but we have to strip the ends of the wire. That can be handy if you want. Um, duct tape batteries. That should dio nothing too complicated. Okay, under the next thing 5. 5 LetsGoShopping: Okay, So in this video, we're going to go shopping. We're gonna find ourselves something to circuit bend, and we're gonna use it for the whole rest of this class. I'm gonna walk you through how I do it. Um, So what I did here is I went around to some stores looking for something, a circuit. Ben and I used my camera on my phone. Uh, and I kind of had to be a little covert about it because I was getting some weird looks like people thought I was like, you know, looking around for a plan to, like, break in and steal stuff. So Ah, that's why the camera work is a little shy looking. I keep kind of turning it away. Um what? And I wasn't talking. So what I'm gonna do is I'm gonna play this video, that I'm gonna basically narrate over it now. Um, I like to go to thrift stores when looking for something to bend secondhand stores. Ah, especially for like, if I'm looking for, like, a kid's toy or something like that, there's no need to buy something new. Um, by something old. Ah, and play around with it and um, you know, spend maybe two, maybe $3 on this thing. You know, don't buy something expensive and fancy that you're gonna circuit, Ben because you're gonna break it. Um, and certainly don't buy something new that has a warranty or anything like that. Because the instant you open it up, you're gonna void your warranty. This is kind of exactly why warranties exist. Is so people like us don't do what we're about to do. Um, okay, so here we go. Let's go shopping. Okay. So I'm in this first thrift store. I found this keyboard, first of all, and it looked pretty cool. This cartridge thing in the back concerned me. Ah, I didn't know how I deal with that and checking out to make sure it will take batteries. It does have this cable coming off of it, but it looks like it will run on batteries. But again, I think I passed on this one because of that cartridge. That little yellow thing that stuck out of the back didn't really know what that was about . I'm just looking at other toys. My hands in the way, Walkie talkies. Not very good, because I don't really make sound on their own. You gotta talk into him. Sometimes a little radio controlled cars can be fun. Um, because they make little sounds, but ah, not that one. It didn't look like it made sound. This dark game was interesting, it looked like because it has a speaker in it. So it looks like you throw it on there and then, um, it makes sounds based on where you hit it, which could be really interesting. Um, because you could make it do all kinds of wacky sounds is he threw stuff at it and, um, looking at cars that ends up not being electronic at all. So I passed on it. It wasn't a lot of this first story went to I'm now in the game section. Sometimes these games could be really fun. Confined cool stuff like this is where you might find, like, speaking spells, which are probably the most popular thing to circuit bend. So I'm just looking at the different games to see if there's any kind of gadgets in them that might be worth checking out. But I didn't find anything interesting over here in the Elektronik section of the store. they have some, like CD players and speakers and stuff. These are not good to circuit, but none of them even like stereos. Um, there really just not good, because, ah, they don't really make sound on on their own. And they're kind of too complicated. Anyway, um, so we don't like this kind of electronic stuff. Stereos looks like a CD player there. Speakers coming, more toys. I think. Now I'm over in a new store. I went somewhere else, and, um, this one had a bit better selection. This was kind of interesting. Elektronik gadget had some barely a little bit of battery left in it, but well, Dora the Explorer keyboard, these things air great. Um, runs on batteries. Makes little sounds funny. What notes you hit could be good, but didn't strike my fancy at that time. But that would have been a good one. His guitar things are interesting. More games, lot, two games. More stuff. I was This was really fun because I was at this store that had never been to before, and there was all these cool little things I didn't really find what I was looking for. And then, like I turned the corner here, and it's like a gold mine, like so much junk. So much cool stuff I could circumvent. Um, so I did end up finding something here, so going through and looking at, you know, different things, like that thing looks like you kind of throw it around, and it makes different sounds, but it looked kind of hard to get into, because, remember, you gotta open these things up, so it didn't wasn't ideal. This, I thought, was really interesting. But after I looked closer, it looks like it's just a holder for an iPod. So you have to plug an iPod into that cable, and it doesn't really do much on its own. Another guitar thing. This I decided not to get because all the buttons play little tunes and I want some of that I can play individual notes on There's the Machete Thing I mentioned in the last video couple keyboards, SpongeBob keyboard. Got a lot of buttons, individual keys. It's got a speaker in it, which I like. Um, it does look a little complicated, but I think that's in the end when I decided, going with. But I'm still gonna look around for another minute and heading back to the SpongeBob keyboard because I think the SpongeBob keyboard is the winner. Little cars keyboard. That was interesting, but I thought if this is going to sit on my shelf, it should be something that is at least somewhat funny. Ah, and SpongeBob is funnier. More funny to me than cars, So Ah, the SpongeBob keyboard is the one that wins. That's what we're gonna be working with in this class is the sponge bob Square pants electric keyboard. Okay, so I bought a spongebob, uh, keyboard. It might be a little complicated, but I think we can handle it. So the first thing I'm going to do is go home and put some fresh batteries in it and make sure it works. Doesn't work. I gotta find something else because I can't really take these things back when you buy a minute store. So have to put some batteries in it and see if it works. Um, okay. So here we are our SpongeBob keyboard. I just put some fresh batteries in it and works. Um, it looks like this key this low c is not working or this a flat So I got two broken keys, but I really care, because I'm not going to use it for, Ah, lot of pitch stuff. I'm going to get really noisy stuff out of this. So kind of OK, it's got some beats built in. This is hip hop. That is the exact beginning of a death cab for cutie son. Anyone? Um, it's got different sounds. Let's stop that. So there's a lot of different things I could do here. It's got a duck sound. The frog. That's Ah, dog and a bird. It's got some cool little sounds built into it. Um, no. One of the best things about Ah toy like this is that it has a demo button. This demo button is gonna be great, because when you press it, it means it's just going to use a whole bunch of sounds inside the thing to play. Ah, and just play a song. Um, which, when we've got it open and we're twisting wires and looking stuff together, we can leave that going, and then we can hear the effect of what we're doing very quickly, Theo. Great, huh? Cool. So we've got ourselves a toy. Um, all we have left to do is talk about a couple safety things, and then it's timeto crack this sucker open. 6. 6 BatteriesOnly: Okay, A couple quick safety tips. Um, not tips. Actually, this is a mandatory stuff. Um, two things we need to cover one is gear and protection of your body while you're doing some of the sauntering and more technical work. And to is a note about voltage and electricity, which is what we're gonna start with in this video. I've already said it once before. I'm gonna say it again. Batteries only. We do not mess with stuff that gets plugged into the wall. Things that run on batteries, particularly audio devices, are relatively low volts. So that means that if you do something wrong now, let me preface this by saying this is unlikely. Um, it's fairly unlikely that you're gonna seriously shock yourself, but if you did do something wrong and you shocked yourself with the entire voltage in the battery powered thing that you're getting, um you're probably only going to get a couple of volts, which will probably just give you a little zap. Um, like a at worst. Like a bee sting. If it's low voltage, right. If you're plugged into the wall and you get exact with the whole 120 volts coming out. If you're in the US coming out of your wall, you're going to get zapped with something that's going to knock you on your but, uh, possibly stop your heart and maybe kill you. Um, it's fairly possible for that to happen, So we're not gonna plug anything in anything into the wall. Um, we're gonna work on batteries only know the ideal voltage that we're aiming for is six volts or less. Six volts or last was a prick. It's not that big a deal to get hit with it. Um, we're going to avoid it because it doesn't feel good, But, um, when you're looking for devices, calculate the volts Now a double A battery. Um, and I'm not sure if battery voltages are standard in other countries. Um, that would be a really good question, but when I talk about voltages right now, what I'm talking about is in the US Um, a double A battery, um, is 1.5 volts. So my little SpongeBob keyboard that I just thought takes three double A batteries, so that's 4.5 volts. Um, that's okay. I don't want to get stung with 4.5 volts. But if I do, it's not gonna kill me. Assuming I'm a super healthy person Now, remember, I'm not a doctor or anything. Um, I'm Well, I'm a PhD, but I'm not a medical doctor. And so I don't trust anything I say when it comes to, um, any kind of weird medical device that I may or may not be giving right now. Basically, we don't want to get touched by electricity. Um, if we do, then we wanted to be very low voltage. So a couple of batteries, Um, and you're gonna be pretty. OK, so my device takes three Double A batteries. 4.5 faults. Not bad. When you're looking at devices, think about, um, aiming for six volts or less, So you could just calculate how many batteries it takes. How many volts each battery is added all up. And that's about how many volts um, maximum could be going through it. Okay, so batteries only, um, no plugging stuff into the wall. Got it? Nothing that we're gonna work on anyway. We're gonna plug our soldering iron into the wall, but no. Ah, toys that are gonna be opened up, get plugged into the wall. I cannot stress this enough. No flooding it into the wall. Okay, enough about that. Let's talk about some, uh, safety gear that you should have in the next video. 7. 7 SafetyGear: okay. When it comes to safety gear, most of this has to do with sauntering. Sauntering is kind of a tricky thing. I'm gonna give you a little run down on how to sauder when we get to it. But, um, what we're doing with Sauder is we have a very hot gun. Uh, it's not a gun. It's basically a piece of metal. And were, uh, melting this this kind of really thin metal onto a board to make connections. Um, I am not a genius at sauntering. There are people who sought. Our work is like it looks like it was done by a machine. Mine is kind of clumpy, which means it's done by an amateur, which is totally what I am when it comes to sauntering. But that's okay. It still works. So, um, what happens when we saw her stuff is that we're melting this little metal wire onto other wires, and sometimes they're convene a little pop in there. There's no way to predict it. And when that happens, um, a little bit of Saudi goes flying up into the air, and if it goes in your eyes, you're in deep trouble. So we're always gonna wear glasses. Ah, safety glasses while we're suffering. Now I know you're thinking No, I'm super cool. I don't need to wear safety glasses. No, you do. Shut up. You need to wear safety glasses when you're slaughtering. Um, Casada is going to go into your eye, and you're gonna be blind forever. Um, so don't do that. Do not sauder without some safety glasses on. Um, I've never gotten any in my eye because I wear safety glasses. I have had it, um, land on my arms fairly often. I think, um, and I get a little burn, you know, you get a little burn on your arms. This stuff is super hot. So, um, it hurts. Um, so long sleeves are also good. I'll just throw that out there. Safety glasses when we're slaughtering long sleeves when we're slaughtering. Um, and the last thing I'll say about stuff you should have for safety. And I don't know if this is true, but, um, people always say to wear shoes. Um, I think that's a good idea. Um, always be wearing shoes because you could drop. You're gonna be working with tools and could drop him on your foot, but also and this is the part. I don't know if it's true or not. Um, when you do get shocked with a little bit of voltage, it hurts less. If you're grounded with rubber soled shoes, I don't know if that's true or not. Um, that might be a myth, but, um, I've never gotten shocked. So because I'm always wearing shoes, maybe I don't know. So shoes, I think are good to be wearing, no matter what. Uh, not open toed shoes, shoes like shoes, shoes, not sandals. So put on some shoes, get some safety glasses, and, um, we're a long sleeve shirt Before we do any sauntering, I'm sure I will remind you of this when we get to the suffering part. But that's enough of that. Okay, so the next thing we need to do we need to start taking something apart. So in the next video, we're gonna dive in and we're gonna take apart my little SpongeBob keyboard. 8. 8 OpeningUpYourDevice: Okay, So the first thing I want to do is open this thing up. Um, so and flip it over now. Obviously, the first thing I'm gonna do is take out the batteries. Um, I don't want the batteries in there. Well, I do this, and I definitely don't want it plugged in. I think I've made that abundantly clear. Um, So here's the batteries to me. I'm still screw cover on the batteries, so I'm gonna take these out. Here we go. Almost. Okay. Three batteries, air out now. There should be no electricity flowing through this. That doesn't mean you still couldn't get a little shock. Um, sometimes these construe or a little bit of electricity, but it's pretty minimal. There's not much to worry about. So now to open this up, I need to go around and find all of the little, um, all of these little holes where there are screws. Every device is different. Obviously a couple tips. So I always make sure you look underneath the battery pack to see if there's a little Ah, screw in here. Basically, what we want to do is there's this line going all the way around and Obviously, this is different, everything but in all devices. But our goal is to separate these two pieces and basically pull this back part off so that we can get access to the circuit board. So I'm gonna unscrew all these pieces. Um, all the little screws I gotta take out, and then, um, we'll open it up and see what we've got. Okay? I've got all the screws out, and now it's time for the big reveal. I think I've got them all out. So now I'm just going to kind of gently try to peel this away. Now, one really important thing here is that there's going to be at least one wire. Probably at least two wires, I should say connecting the batteries to the circuit board. So this isn't going to come all the way off? Never just ripped this off because it is going to be attached. So we're going to kind of gently move it aside, see if I can get it. So you get a good view. Okay, So here's the inside, and the bad news is not really seeing what I want to see. What I want to see is the circuit board, and it's not quite here yet. Um, there's a switch right there, which is interesting. I wonder what that does. Um oh, I see. It's Ah, that's the on off switch. This is the other side of it. If we flipped it over, this would be the on off switch. When you turn that, it hits that. I see It's kind of weird way to do it, but it works. So I think the actual circuit board I got to go a little bit deeper. I think it's gonna be underneath this, So let's try that out. I got a couple screws here that I can pull out. Okay. Therefore screws holding that on, so I should be able to lift this up. Now, that's what I'm looking for. Okay, so here is the circuit board. This is great, cause this is a nice and simple one. Um, there's probably a microchip somewhere, maybe on the other side of this other piece. But this might be enough to get me what I want. Because what I'm looking for is all these little metal points. These little sauder points because I'm going to jump into those and connect him to basically make little short circuits all over the place. You can see this is kind of fun. These air, little rubber stoppers, these air What the keys hit. So these little points here hit the keys, and that's what triggers and note was kind of fun. No one really crucial thing here to note that I have not disconnected anything. So if I put the batteries back in right now, everything works right, cause I didn't pull any wires off of anything. I just pull the plastic apart, so everything still should work. I've got my circuit board out. Ah, and now I can start to have a little bit of fun with it. 9. 9 MakeAJumperWire: wait. The next thing is, we need to make ourselves a little tool. A jumper wire. So all this is as I'm gonna take some wire. Um, this is black wire. You can use any color wire you like. This is totally temporary. This is not what we're going to actually sauder in. We're gonna use this to test different points to see if we get cool sounds out of them. So I'm gonna take a piece of wire. I'm gonna take it to be about the length of my circuit board, which is about that long. Plus, I don't know, a couple more inches. Um, Max, you don't want this super long, but you want it long enough to connect any two points on it with some despair. Um, but not a lot. So here we are, so I'm gonna cut it, so I just have the wire. Now I'm going to strip the ends of it. So this is a pair of wire strippers. If you don't have wire strippers, you can use a knife by just kind of carefully flicking off the end. We don't want a ton of extra space about like that. I think you can see that I m something about like that. Do that on both ends. So now I've got both ends stripped. Now, I'm just gonna kind of fold them down into a right angle. And so this is good wire that will, like, hold its shape when I do stuff. So now I've got two points, like a little stethoscope. Kind of because so now what I can do is basically go like this. I can pick any two points on the circuit board, put one down another one down and then, um, hear what it sounds like. So I call this a jumper wire. Um, we're going to use it to test. 10. 10 MakingFirstConnections: Okay, So now we've got our jumper wire here, and we've got a circuit board so exposed. So the next thing we need to do is just make some sounds and see what happens. So the first thing I'm gonna do is put the batteries back in. So being very careful because you can easily break something here. Remember, the key is to not let anything get disconnected. Okay? My battery's air back in now. I need to figure out how to turn it on. I'm pretty sure this is the on switch. I could also flip it up. Here we go. And now it's on. I can play it by doing that. Now, this is where that demo mode is gonna come in handy. So fucking or figure out how to turn that on by looking at it upside down. There it is. Okay, now, this is the worst part about circuit bending. Is that you're gonna have to hear this little song over and over and over. But let's try to bend some stuff, Okay? Hopefully you can see that. So I'm just gonna pick a point and I'm gonna two points. I'm gonna connect them. I'm gonna hear what happens. Did my demo run out? I was hoping that it looped. That means that every few minutes I'm gonna have to go back and hit this button. All right, Here we go again. Let's connect that. So now I'm just holding down one point, hitting a few different things. Okay, Okay. These too short. So when I connect these two points, it shuts down. I shorted it out. It is okay. I just got to restart it. Ah, and then not hit that again. So we're gonna make a special note of that in a minute. I'll show you how to do that now. Ah, lot of the time. What I'm looking for is a group of stuff. Like, I think there's good stuff here. So I'm gonna stick to the same point on the left and cried over here. I got not a short. So I think the short probably is coming from there. We don't like that one. All right, one more time. Let's try one of these. There we go. Okay. I stopped the thing, but I didn't short it, so that was interesting. Try these two. No, I keep shorting it out. So over here and I get anything there. Okay? I didn't short it out. He just ran out on the song. Oh, came triggering stuff now. Okay, so I think this section is responsible for triggering stuff. Not necessarily the sounds, though. Gonna short. Um, tricky. Okay, I have a theory. Stop this. So my theory is all of this stuff. Most of this stuff is controlling the patches and the notes and the actual sounds that we want to get at is underneath this. So I'm gonna try to pull this off and see if I can get to it. Okay, I got that flipped over, and here's what I discovered. So I was right that there was another circuit board under there on the question is, are my sounds in here, or is this more control information which I'm very curious about, cause it doesn't. I don't see a chip that I was expecting, but let's goof around with it and see what we can find. So now I have a little bit more complicated thing because all my buttons now are gone. I mean, this whole piece of plastic is gone, so if I want to turn it on. I gotta figure out how to do that. I'm pretty sure that's this switch right here. There it is. Now, where was that demo mode? It was one of these two. Nope. Oh, there it is. Let's see what we find. Okay. I found a way to short it. Okay, Well, I found a way to trigger that snare drum. Could do that right there. Okay, so I've been playing around with this now I shut the camera off, so you didn't need to watch me and just goof around with that. But I was basically just testing all kinds of stuff. Um, just throwing these two wires all over this wire all over the place and listen to what happened. I didn't want to subject you to listening to that little tune several 100 times, which is what I just did. Um, but I think I found a couple of interesting things. They tend to be between this region right here and this region here. Now, this region. I had a clue because if I flip this over, so ah ah, unit like this, That has a lot of sounds in it is probably it. Most of those sounds are probably stored on a chip. So if I look around here, I don't really see a chip. A chip is like a big black thing. Kind of looks like an eraser from a pencil. But if I flip this over, look on the other side. I don't really see a chip that's not a chip. I hope you can see that That looks like a like a pencil eraser, but it's not. That is a chip, so that's probably where the sounds are. So if I follow that to the other side, that gets me these eight sauder points. So those are probably where the sounds are. Um, from there. I just started experimenting, and I think my favorite sounds. Here we go again. Done an a r between. See, I think it was this one here, and that's kill. There's a couple good ones that around here it's kind of a cool one when the sound is happening. There was actually some pretty cool, really gnarly distortion. Just one even better one here somewhere, like that's my favorite one, because also remember that we're only hearing this demo play. But some of these bends will affect the keys differently. Um, different sounds differently. Um, so ah, these sounds that I'm finding tend to be these big distorted tones. Um, which I'm kind of cool with. If we kept poke around long enough, we could probably find some other interesting stuff. But I'm pretty happy with that. Now, the next thing we need to dio once we kind of know what area we're looking for. Way need to do a little bit of planning because the next thing we need to do is is going to be sauntering, and we kind of only get one shot at that. I mean, we can unsought er, that's a thing. But it's hard. So Ah, what I'm gonna do is figure out how to make a map of what's happening and from that map will be able to plan our bends well. So in the next video 11. 11 MappingConnections: Okay, So the next thing we need to do is figure out what bends were actually gonna make now that we've experimented around a little bit. So here's how I like to do this. Um, this is just sort of what I came up with out of necessity. Um, and it seems to work pretty well. So Ah, what I've done here is I've taken a photo of the circuit board, and I've really only taken a photo of the parts that I'm gonna use, which are this part. Um, so this is where that chip is is right here on the other side. So and these fours, where I was getting the best sounds and these ones down here connecting those together, I have no idea what these do, but it makes a cool sound, so I like it. Um, So here's I'm gonna do I'm going. Teoh label these. Ah, and basically come up with a little schematic. So normally, I just print this out and do this by hand, but I'm gonna try to do it on my computer here. Okay. So I'm gonna call this, so I'm just gonna draw a box around this. These four Ah, and then I'm gonna call this section A. This is a And then it's gonna be 123 and four. See if we could make those a little smaller. Okay? Perfect. A 1234 So this top one is a one. This is a two. A three in a four. Right. Kate, Let's make another box. And let's put that around down here so I might need to divide this into multiple boxes. Let's do that. And then we'll call this be. We'll make that be nice and big, and then we'll call, say, 123 456 those a little smaller and I'm gonna put those right there. That worked pretty well. Let's push that six over. Okay, so 12345 and six of the B section starting to sound like a tune, and then one more in my case is going to be these ones down here. These four is also getting good sounds out of, so let's call that see? And 123 and four, Let's just do that and then we'll make them a little smaller as well, so that I know what's what and my labeling here is really arbitrary, but, um, it's just so I can keep track of what's happening. So now I've got this document I've got. So I know this pin right here is a four. Right. And this pin right here is ceased four. Because that's 123 and four. That's a little elusive. Let's push that up like that. Okay, so this is C four. So if I know that, that's a connection I want to make, I'm just no tape that there's gonna be a switch on a four to see for, right? So I'm gonna make a list of the couple I'm gonna add. I'm not gonna add a town in this one. Um, probably four switches, I'll add. So let's figure out, ah, what Ben's I'm gonna make, um So I'm gonna jump back over to my ah circuit board and figure out which ones I'm actually going to do, and then I'm gonna notated in this space right here. So let me pause to do that and come back, okay? I found the four that I like the most. Um, and you could do is money as you want here, but I'm just gonna do four. Because I don't have a lot of space on this to mount switches. And I'm not finding as much interesting as I hope you are on your device and finding some cool stuff. But I'm not finding as much as I found in that big keyboard of mine. Um, someone's gonna do. These four on before I found are a one that's this one to be six. This one a one to be three. Ah, be four. Just this one to the right of a one. That's that one. I didn't have that. That's not in my box. So, in fact, let's just do this. Let's extend that out, and then let's can I paste that? Let's do that and call that five and six. There we go. So now, instead of calling it right of a one, I could just call it Ah, a five. So before to a five, which is No, that and a to this one to be three. This one. Now, one thing you might notice is that a couple of these have multiple connections on him, right? A one has to ah, be three has to, and I think that's it. And That's okay. They can have multiple connections. Um, we can do that. We can hooked to wires to the same spot. Um, if we end up hooking a lot of wires toe one spot, what we do is we hook one wire to it, and then we hook all the other wires to that wire. So we basically use one wire to jump off of it and all the other ones to the same wire, and you can use a little break out board. I won't talk about that later. Um, but these are the ones I want to make. So I have identified my spots. The next thing we need to do is decide what kinds of switches we want to put on this thing , Um, and then get down to sauntering and putting it all back together. So in the next chunk, we're gonna talk about switches and connecting things with sauder. So off we go to the next chunk and I'm gonna put this little schematic up on the ah ah, up in the class for you So you can download this and look at it if you want 12. 12 TypesofKnobs3: Okay, so the next thing we need to do is find ourselves the right switches to use. Now, how this is gonna work is we need to get some kind of switch because that jumper wire that we've been using is only a temporary thing. What we're actually gonna do is we're gonna hook a wire, a shorter wire to one of those spots and then another wife to the other end of those spots and then the other ends of both those two wires Teoh a switch so that when that switch is off, it's the connection is not completed. And it sounds as though those wires aren't there at all. That's the idea. When that switches on, it completes the connection, and it's just like putting their jumper wire on there. So that's what we need. We need a switch settled, able to do that so you can find these all over the place. You can go to local hobbyist electron ICS shops. Um, if you don't have a place where you can get these nearby, check out this website spark fund dot com. This is a great website for doing pretty much exactly what we're doing. They have projects and tutorials and a blogger and all canticle stuff video walk throughs on how to do you some cool electron ICS projects. It's a really fun website. So I'm gonna go down here to components, and then I'm gonna go to buttons and switches, Okay? Now, here is a bunch of different kinds of buttons, right? Uh, tons of, um, come different kinds of buttons and switches. So I'm gonna walk you through a couple of these and tell you what I'm looking for. Um, What? I'm looking for a button for a project like this or switch. Actually, let's look at this. 1st 1 this is ah, little joystick. Now, this is like the exact same component that is the joystick in, like a game controller, like a PlayStation or an Xbox game controller. The things that use your thumbs with, um, those are cool. You could do some fun stuff with those, but those are not right for what we're doing because we need this. Ah, switch that has two states and on state in an off state, right. It's got to be honor off and we don't want anything in between. This has basically an X Y coordinate, and it's gonna be a lot more complicated than just in on and off. That's not gonna work for us for this project. Ah, this one, This is ah, kind of mini trackball. So same deal. It's not gonna have to states. It's not gonna have an on and off. It's gonna send something much more complicated. That's not gonna work for us. This one is a momentary button. What that means is that this actually does have two states. This is on and off. So that's good. And we could use this. Um, I'm not gonna use this one because it's a momentary switch. Know what that means? Is that when we so basically it's off by default, and when we push it down, it's on. When you push down the button and then we let go, it's off again, right? So you've got to be holding it down. And that's not really what I want to do with this kind of thing. Because on my little keyboard, what I want to do is be able to flip some switches, make the crazy sounds and then be able to jam out on it. I don't wanna have to hold the buttons down. Right? So if I was making something like maybe like a drum trigger thing, you know, something like this might be more appropriate. So keep in mind a momentary thing. That's what that means. Arcade, Joystick. These are sweet, but for the same reason as a stump joystick. Not cool for us, because not going to give us an on and off. But check those alto. You could just buy these arcade joysticks. Totally awesome. Here's a push button. I think this is probably a momentary one. If we wanted to use it, we could, but it would be that momentary thing. Um, but we could look more added to see. It also might be huge because it's $10. So this might be like a big, huge red button which we don't want because we got to be able to fit this thing inside our enclosure. Right? So in my case, it's going to be way too big. This one, however, is just right. So this is a toggle switch. Click on it to get a better look at it. So this has two states on and off. Um, it's exactly what I need. The only thing that concerns me about this is that it might be too big. This part of it down here is pretty big. And I've got a pretty thin device. So whether or not even be able to cram this in there, I think I'll be able to do it. I don't think I'll have any problem with that. It also has this washer here, which makes it mounting it on the device a little bit easier. Uh, and the last thing that I look for in stuff in these kinds of switches as I don't want to switch that requires power. Right. So that is to say, the switch itself needs power to operate. This one does not need power. Let me show you, for example, something like this one. This one is pretty much the same switch. Except it has this lighting up red thing. It's got lights on it, and it's a button that lights up. Then you need to send it power. Right? So this says, you know, it can It can work for his Lois 3.3 volts. So you might be able to on your device, find a way to send some voltage to the switch, but that gets a lot more complicated. And I just don't wanna deal with it. So I don't want to switch That requires any kind of power. So no lights on it. Nothing fancy like that. So that makes this one the perfect fit. And they're only two bucks. So I'm gonna order for these, And as soon as I get him, then we'll put it together. So? So the next thing is gonna happen is ah, I'm gonna wait like, ah, 5 to 7 business days for these to show up in the mail. Uh, and then I'm gonna put it together. But luckily for you, because of the advancements of technology, it's gonna be right in the next video. You're not gonna have to wait a week, so off we go. 13. 13 soldering tips v2: Okay, Uh, we have gotten our switches and mail. This is what they look like about what I expected. Um, there, you know, good and big on this side, which I love it. If they were a little thinner this way so I could fit him in the case. But I'm pretty sure I can fit them in the case, I kind of size it out, and I think we'll be just fine. So, um, before we get in doing this, a couple sauntering tips I've got here My Sandra sauntering iron. Ah, it's good and hot. You can probably see some, uh, steam or smoke coming off of it. Um, I also have one of these. This is just basically a holder, so this coil thing will hold it. Remember, this thing is incredibly hot, So if I put this on the table, it's gonna burn a hole through the table, or at least burned the table. Now, I've put this would board down so that I can get it kind of marked up and not really cares . So see, I just burned a line in it. Um, that's okay. This is like scrap wood. Um, that I have here. This is not my normal desktop that I put on here. Um, it's also has a magnifying glass on it. Should I need to do that to zoom in eso this thing can be handy. And I also have here. Let's put that down and away. Little balance. I also have here a slightly damp sponge. This is handy for when you get too much sauder on the iron. You can kind of wipe it on here and ah, uh, clean some of that off. So this is gonna be trash when we're done, but that's OK. Um, okay. So I can smell the sauder. It's going, uh, it's already getting kind of hot. So this is the sauder. This is just some extra sound I had laying around. I don't anything fancy. So this is just kind of a watered up ball of it, but it's basically this really thin wire. You can get thicker stuff if you want. Um, I just like toe watered up in my hand like that, and then leave a bit of it out. That's what I'm gonna need to do. So remember our safety stuff. I've got my glasses. I've got shoes on. I've got everything I need to do this right and safe. So what I'm gonna do here is I'm gonna make about eight wires like this one. This is our jumper wire that I cut in half and I stripped both ends of it. Um, now you'll notice that on the far end up here, I have stripped it really short. This is what we want for these because these are gonna be our permanent wires. So with the stripping that we're gonna do, uh, we want it just a tiny bit of that wire poking out because we don't want it to be able to touch anything else. So I gotta make eight of these because I have four points that I'm gonna saw her. So I need one of these connected to each spot. Now what I'm gonna do here is I'm gonna do this in kind of a weird way. Um, that will set me up to be able to put this to back together nice and cleanly. I hope that's the hardest part. Is putting this all back together with the new switches in it? So, um, I think we've covered everything you need to cover. So, uh oh, a couple more sauntering tips. People always say that to remember that suffering is not gluing. Um, that's what people always tell you when you're learning sauntering. Remember that I said earlier. I'm not the best that saw during, uh, I'm OK, but I'm not super elegant at it. So, um, the idea is that we're gonna touch this piece of metal to this spot, the wire right to the spot that we want connected to. We're going to get it good and hot by touching the iron to it. And then we're gonna touch the Sauder to it, and we're gonna permanently connect it to that spot as all gonna happen pretty quick. So hopefully I'll do it in such a way that you can see it. Um, last thing I'll say, Don't forget, this thing is blazing hot. Um, okay. So, uh, yeah, uh, if you're inside open window, will you do this Because things are going to get a little smelly once we start melting. Sauder. Okay, so here we go in the next video, we're gonna dive into start putting this thing together. 14. 14 ConnectingWiresToTheBoard v2: Okay, let's get down to business here. So I have eight wires all set up. I have, uh, green and black. I'm going to use. I'm gonna alternate between the two. Uh, it'll make it a little easier to keep track of. Now. What I'm gonna do here is I'm gonna sought Are all these wires coming off to the sides? Um, and then well, about half of them going off the left side and half of them going after the right side. Because I'm gonna put the switches on either side. I'm just gonna kind of aim in that ballpark for now. I can do some adjustments later. Uh, and then what I'm gonna do is as soon as I saw her one down, I'm going to use some scotch tape or not. Scotch tape. What kind of tape is this? I don't know. The kind of tape you can write on really well. And I'm gonna right, I'm gonna label Ah, the wire. According to the chart that I made earlier. Ah, so that later I can connect the switches. So first step right now is I'm just gonna connect the wires to the circuit board, and I'm gonna connect the switches later, so I want a white label them as I go. So let's do our 1st 1 So I'm gonna start with black wire. So the 1st 1 on my list is a one which is right. See here, Here. Right? Yes, it is that one. So I'm gonna dio kind of tricky with my microphone here. But now a lot of the time. Here's the trick. A lot of the time you don't need any sauder because there's already saw her on there. That silver stuff is sauder. So what I could do is I can see if I could just jump right onto it by touching my iron to that sauder heating it up and trying to get my wire in there. Almost. Okay, this is a little tricky. So I'm gonna need to shorten the part of this that stripped because I need it really tiny for this one because I don't want the exposed wire to touch anything else. And if I laid off to the side, it's gonna Okay, let's try that one more time. It's gonna leave this right down there. Just touch the iron to the sauder. That's already there. No. See if I can get it to stick. Okay? I'm getting it to stick a little bit, but it's not working. Great. So I'm gonna put some sauder on it. Now, if you only have two arms. Like most people, what you can do is you can separately put a little sauder on the wire. Okay, So that soldering iron was actually my old one. And I'm gonna There's a reason I have my old one out. Not that I'm gonna get to in a bit, but, uh, really, it's not getting hot enough to do this, so I'm going to my other cheap soldering iron. Both of these are super cheap. And let's try it now. So without putting any sought around there, let's see if I can get it in there. Now that I have a better soldering iron, I'm melting it. But I'm not quite getting it, so I'm gonna use this technique again. Just putting a tiny bit of sauder on the wire. You don't need much, okay? There is just, like a little tiny drop of sauder there. You probably can't even see it. So now that it's on the wire, I'm gonna put that on the spot and try to melt the Sauder to this spot. There we go. We got it. We're on there. Right. Okay, so give that just a second to cool off, and then it should be pretty sturdy when it's on there is good is gonna be. Make sure it's not touching anything else. Ah, and then, Ah, we're good to go. So I'm gonna finish up all these and, um, make all of these connections, aiming them off to the side for now. Ah, and then I'll jump back in and show you what? I'm all done. Okay, so here we are. I have all of the wires connected to the board. Um, a couple things. A note. So what I did is I took the 1st 2 in my list, and I sent them going off this way. That's these four wires I took a second to and send him off going that way. That's these four wires. I've labeled them all. So this one says a to s so that I could get to the other end, and I know what I'm doing. Um, now, if you remember, there was a couple spots where I needed to, uh, connect multiple wires to the same spot. So that's like here. You see, there's two coming off of this top one. I'm not sure you can see that, but and they're just stacked on top of each other. And then there's kind of a glob of sauder on them. There's another one down here, right there. Um, where there's, like, a little glad Now if you needed to connect a whole bunch, what we would do is we would connect one wire to a little break out board. You can buy these little boards that basically have one slot, and then you're like one slot and then a piece of metal that connects him to a whole bunch of other slots. So you connect one wire to that slot and then a whole bunch of other little wires to that, and then those would go to the other point er to the switch so we can do that. So now that I've got this all set now, the next thing I want to do is figure out where the switches air gonna go. That's going to be really hard, because, um, there's not a lot of free space on this board, and I'm gonna need to, like, punch a hole out of the board and get those switches in there. And then I'm gonna try to reconnect it and close the whole thing up and try to make it look as normal as possible. It's gonna look a little Frankenstein and weird, but that's OK, so, uh, onto that 15. 15 MountingSwitches v2: Okay, So sorry, I'm gonna have to use my handheld laptop for this one. Um, for this first part of this one. Anyway, don't worry. We'll get less shaky in a minute. So here's what I need to do. I need to figure out where on this thing when I flip it over. Am I gonna put these switches now? You can see my little orange pieces, all my buttons and stuff that's have all fallen out and they're stacked here on my desk, and that's okay. I think I'll be able to put those back in just fine. I hope this orange one hasn't fallen out, but there's no reason it couldn't just push it out with my thumb. Just let's get rid of that Because and the keyboard to, uh came out, and that's just fine. Those we're all gonna get in my way for a little bit. So if they easily come out and I could just wedge him back in, then I'm gonna take him out because I don't really care about them for the moment. So I think where I'm going to try to put these two switches are here and here. These two spots and on the other side here and here, Right? I could use this spot because this is nothing. If I look at the other side of it, this is just a piece of plastic, so I could poke through there. Ah, and put them, you know, around in that area. Or I could use this speaker. That's what I did on my other keyboard. I used the speaker that was in it where I took out the speaker and put the switches where the speakers were. But this will only really let me fit to, because they're kind of big and bulky, So that's not the best one for me. I'll leave the speaker intact and, ah, try to use these side areas. Now what? I need to dio look at the back and I need to find when the circuit board is in place when it's in there. Is there anything covering up those spots? Meaning when we put the whole thing back together? If I have switches in those spots, is it gonna push against the circuit board? That's what we don't want to do. So the only thing that could be in that spot is the is the board that controls the keyboard , which is this long one, right, cause there's all the keys, the little rubber things. So I'm gonna do is I'm gonna measure this piece and see when it's in here. Is it longer than this opening? That's what I care about because if it's longer, it's gonna go into my spots where I'm gonna have the switches. So already did that, and it's not. It's actually shorter, which concerns me a little bit, because that doesn't seem right, But it's a little bit shorter, so it will only come to about here and about here. So I should be free to use these two spots. I couldn't put it all together and figure that out before committing to it, but I like to live dangerously so I was gonna do it. So I've made too little black marks here with just with a Sharpie with a pen. Um and that's where my holes were gonna go. Now what I need to do on this switch, I need to make a hole big enough for this screw part to get through. Because I'm gonna do is I'm gonna take off this washer, which I might need two hands to do. So I'm getting that going to take off this washer, okay? And now I'm gonna make a hole big enough to get through with this, and then I'm gonna put the washer back on on the outside, and that's gonna hold it nice and firm and in place. So if that was confusing, you'll see what I mean. I could actually take this on off peace out as well. Maybe I don't want the on off peace. Doesn't matter. I don't need it there. Cool. So I'm gonna make these holes. Now. The way I'm gonna make these holes is not the ideal way The way I do this is kind of dumb, but it works. I'm gonna take my cheap, sauntering iron that I showed you earlier. You'll notice that the end of this is all black and gnarly. Because when I use this for is to burn a hole through these spots. It smells terrible, gets burning plastic. It's probably not really good to breathe at all, but, um, I'm gonna do it. I'm gonna try to do it quick so I can try to burn a hole through these things and see what happens. Here we go. Okay, so I have a nice hole in there. Let's pull that into focus. Focus. Here we go. So here's what I had to do. I had to poke my sauntering iron through there, and then I had to kind of weave it around in a circle toe, widen it out just a little bit more than the iron was wide. And then I had to destroy this thing on top of it a little bit because the block is actually of the thing goes just like that. And I needed a little bit more here and a little bit more here, so I just kind of widen those out for. The next thing I'm going to do is I'm gonna sand down the edges of this on the other side. Actually, I'm both sides so that because you can see there's a little bit of a lip from the burning, and that's gonna get in the way of that screw going down. They're nice and solid, so I'm just gonna sand those down a little bit. Eso that that's kind of smoothed on top, and then hopefully I'll be able to get my switch right in there, So a little bit of sanding and then I'll be back. Okay, so here's what it looks like. I've sanded off around the edges. It's a smooth that out a little bit. It's not beautiful, but it works. Um, and on the other side, I didn't do much standing on the other side because it was too hard to get down in there. And this is the inside, so I don't really care about what it looks like. All I really care about is if this switch is gonna be able to go through far enough for me to put that screw back on it to hold it in place, and I think I'm gonna be able to do it. So let's try. Okay? Our first switch is mounted. Not too bad, right? Like it's on there nice and solid. I was able to get it through and get that washer just barely on because it's pretty thick casing. But it was able to get through when I got it on there. Just finger tightened this. I can tighten it a little more, uh, with a wrench if I want to. In the end, on the inside. This is what it looks like. There's are two connections and there's where it sits. I think it will be okay like that. So I'm going, Teoh, put the next four in their next three in there. I should say, uh, and get all my switches mounted. And then all we have to do is a wire him up and put everything back together. So I'll be back after I get the next four for three installed. Okay, so here we are. Um, that switches are mounted. They look really nice. Actually, there's to you There to there. I was able to get those in pretty much. OK, The hardest one was that 1st 1 Um, but you two are just fine. Now, you might be asking yourself which way is on and off. I'm just always just mount him in the same direction. So I've got the pins going down at the bottom of all of them. So whether or not up is on or down is a on, uh, they'll all be the same. So that's all I really care about for this. So the next step that I need to do is ah, connect these switches to our dangling wires. You know, the first thing I'm gonna do is put it back together. I'm gonna put everything back together as much as I can with still leaving me access to those dangling wires so I might hide the circuit board. I'm basically gonna go as far as I can before I cover up access to those switches. So I'm gonna start that right now and see how far I could get and then I'll jump back in. 16. 16 ConnectingSwitches2 v2: Okay, so I was able to get the whole thing pretty much back together. I mean, I still have the two big pieces separated, but, um, I got both circuit boards screwed in and down, locked in place. This one had a hard time going in because of the extra wires. So remember that when you screw these things in, you're gonna have extra space, so you're gonna have to push him in their harder. So you want to push him down in hard, but you don't want to break anything, so you kind of have to negotiate it. This is why we ran the wires off to the side and not pointing up, you know, like screwing them down, going up because they would create even more space. So if you push him down to the side, we can put a little bit of pressure on him, and it's not gonna matter as much. Now, I did screw up one thing. Well, probably a lot of things. Once we actually fire this up, there's probably a lot of chaos happening, but, um, and the thing I screwed up now is that you can see my wire sticking out. So here are the two that are going to go to these two switches. So one side to each one of these air to black wires here are my two green wires. So they have to reach over there to sew those air fine on that side on this side here, my two green wires. So I need one of these going to each of those and then here my two black wires. And that's it. That's my screw up those air Too short, um, they're not gonna reach. This is his tight as I can pull home and they're not gonna reach there. So I have two options. I can open everything back up, and I could screw in a longer wider or sauder in a longer wire, Or I can extend these wires and I'm gonna show you how to do that right now. How we're gonna do this is we're gonna hook a second wire to it, and then we're going to use a little bit of this stuff. This is a like it's like rubber kind of. But it's called heat shrink tubing. So what you do is, uh, you heat it up and it drinks. It's like a little shrinky dink. So, um, I'm gonna cut off a little piece of this. We're gonna need to, and then I need a piece of wire I have right here. I don't eat much, right. I just need a tiny bit more to get to their. So, um, let's go like this far this one. I'm gonna strip both ends of it just like before. It's pretty good. Now I'm gonna do is I'm gonna take one of these wires that twist them together a little bit . Now, one way you can do this is to line them up. So one of them's going the opposite direction. Kind of for come like that. I think you can see what I'm doing. I hope and then twist. Um, together, This is really hard on your fingers, but that's not too bad. Um, now I could put a dab a little dollop of sovereign there. I kind of don't really need to, though, cause what I'm gonna do is been this one going this way, and I'm gonna put a piece of tubing on them. This tubing is probably a little too big. So we had some thinner stuff, but I don't. So do that groups. So I'm gonna get him hooked together, Put this little sleeve of stuff around him like that. Now I gotta let it on fire eso Let me get myself a, uh, lighter. I'll be right back. Okay? I now have a lighter. So what I'm gonna do is try to prop this up a little bit. Gonna look in there and make sure they're still connected. I'm gonna keep my fingers nice and far away and to see if I can. She had a longer later. Just burn this down a little bit, okay? Hopefully it's not on their very well shoot. So this is not working out as well as I wanted because this heat shrink tubing is just too big. It's not gonna get tight enough to really hold these on there tryto because when this stuff shrinks, it only shrinks so far. Well, that sounds really good, though. I think I got it. I'm gonna call that good. And then when I put this together, I'm gonna make sure that that doesn't get any a lot of pressure on it. Um, cool. So I'm gonna extend the other wire and then I'll be right back. Okay? So the next thing I have to do is I just have to go through Ah, my chart that I made earlier and connect the two points. So my 1st 1 is a one foot up here, Anyone to be six. So I just had to find my A one wire might be six wire. There it is. And connect them to one side each of the switch like that. So I'm gonna sauder those into place, making sure that they're not touching, because that would defeat the purpose of the switch completely and to make sure that they're laying as flat as possible. And I'm kind of maneuvering the wire as I do this to make to make it get in the way as little as possible so that I can still close this backup some to do those things, and then I'll be right back. Okay, uh, my switches are connected. Eso I got each one connected and the wires kind of snaking around to avoid thes kinds of holes where I'm gonna have to put a screw through to hold the whole thing back together. So I don't want wires in front of those, um, I do have wires hanging over the board here, but I think I've got electric space right there when the board closes. So I think that will be fine if that we'll find out in a minute. So I just wired the screws through the put the wire through the hole on the switch, and then he's put a little blob asada on there, making sure they didn't touch nothing fancy. That's actually probably the easiest sauder job of this whole operation. So before I close it up, I can kind of have a little moment of truth here, can I, um, because everything's working well, should be working. I'm trying it yet, but I still have batteries in um So, uh, I could actually I think I could just do this and I should be able to see what happens. So in theory, when I turn it on now, all my switches are up, so it's gonna be a whole bunch of noise because all four of those circuit bends are going to be active. And remember, we never tested what multiple bends at the same time we'll do. We only tested each one. So when multiple things are being bent. It might just be crazy. So in theory, it's gonna be, um, a lot of noise when I turn it on. But the real test will be When I turned all four switches off doesn't go back to a normal keyboard. That means I did it right. Um so let's try it. It's awfully quiet way go. So the switches are are backwards when they're down there off when they're on with them all off. Okay, but I still have my keyboard missing a couple of notes, but I can switch some stuff on what's really quiet. But it's still a cool sound. No, enough for that one. Bussiness like a cool popcorn sound was turned on. Uh, awesome. So I'm pretty happy with that. I think that's fun. Um, now, remember, we didn't find a whole town of really awesome bends. We found these really noisy ones in this keyboard, but I think it's still cool for making good, noisy sounds. And there's probably a lot of really interesting stuff in these little drum loops that we tried out earlier. We just tested. The key is that time, uh, my speakers still works. Eso I'm ready to close this whole thing back up and call this project done. So let's do it. So I'm gonna do is back over. Everything's really in place. So all I have to do is put this back on. I had to turn it around. Hopefully, it falls right back where it belongs. Should I kind of feel it? Click in? It's gonna be a little trickier to get back. There it goes. All right, so now I just gotta put those screws back in and we'll be in good shape. 17. 17 SwitchDetails: Okay, We're all done. I put all the screws back in, went in pretty easily, uh, concerned my device on my cool sounds. I can play it just like it's pretty awesome. Ah, good. So I'm happy with that. Uh, everything's all back together in one piece. Really solid. Nothing rattling around on the inside. Uh, so I just couple cleanup things to do, and then we'll be done. 18. 18 ClosingItUp: everyone. So I just wanted to point out one more thing before we wrap up here. Um, I don't think I was explicit about this, and this is something that gave me, um, something that took me a little while to figure out when I first started doing this. So I wanted to point it out for you. So we're looking at here another toggle switch. This is a different model than the one that I used, but, um, it's basically the same, right? We've got two pins down here and we've got a toggle switch. So, um, if you were asking yourself which wire goes to which pin Ah, the answer is it doesn't matter. In this case, all we're doing is completing the circuit. So whether or not you put the black wire or the green wire in my case or one of the other, it doesn't matter which, when it goes to, um, you can switching off. It doesn't. It doesn't matter at all. It just is. One goes to one of them, the other one goes to the other one. And then when the switch is on, the circuit is completed. That's all it is now Another thing to point out here is that if you're having trouble ah, connecting to these little holes, here's a trick. A lot of time. What we do is we pull. We put the wire in this way, and so the end of the bare wire is on the inside. Here. Try doing it the opposite way. Put the insulated wire in the middle and poke it out. So the the stripped end of the wire is poking out and then do the same thing on the other side. So these air pointing out and then put a little dollop of sauder on the outside that will keep the tips from touching. Because if they touch that, it's basically always gonna be on. So we want to avoid that. So have the wires come on the inside and then bend them to push out, Uh, and that will get you a more secure connection. So I just wanted to point that out about to switch, because a lot of people I've seen get stuck on that. Which wire goes to which end of it and the answer for these kinds of switches Not all switches but in these kinds of switches is it doesn't matter. We're just completing the circuit. So there you go. Little bonus tip 19. 19 JammingOnIt: Okay, so we're done. We built this cool thing. Ah, I'm pretty happy with it. I cleaned up my Mesler on my studio Here is tends to be a fairly messy process. Um, I've got my cool new toy. Ah, and so I'm gonna jam out on it. Now s So what I did is, um I made ah, short, little tiny track with it. Nothing fancy, but just kind of exploring some of the sounds. So because this thing is so noisy what I did. Ah. And what I would do with almost all circuit bent stuff is I recorded the thing into a built in, which is the dog that I use eso I recorded it in, and then I chopped it up and started working with a sound. So in this track that you're about to see and hear in front of you, this is just all sounds of the keyboard. I did this really quick. It's something brilliant. It's just kind of to show what you can do with this kind of ah sound. And really, what would be more interesting? Is layering this with some acoustic instruments? Maybe. Ah, some really natural kind of wood sounds, I think would sound really good in here. But I just wanted to show you what you can do jamming out on something like this. So here is Ah, cool little fun track that I put together for you. 20. 21 ThanksBye v2: Okay, everyone, we are all done. Thank you for checking out this class. I hope you had a good time. I had a lot of fun. Uh, this was a great excuse for me. Teoh, make another circuit bench toy tow. Add to my collection. I hope that you, uh, followed along and were able to make something cool on. If not, maybe you can revisit this class when you're ready, toe, actually do it all along with me. So thanks. Uh, check out some of the other courses. Have a good time. I'm gonna leave you with one very last piece of advice slash caution. And that Is that just because you know how to circuit bend something now, that does not mean that you know how to wire the electricity in your house. Very different things. What you know about circuit bending now is very rudimentary about the Elektronik side of it . We didn't really do anything with the electron ICS. Um, you know, we connected some stuff when we made cool sounds. Don't try to, like, you know, rewire your house. Based on the knowledge you learned in this class, you're going to hurt yourself very badly. um, and maybe burn down your house and more houses. This is a very foolish thing to do. So remember that what we learned in this class was just really basic batteries, only kind of stuff. Um, when it comes to electricity and when it comes a circuit bending, we know everything we need to know. You can pop open anything. Now, find a couple spots, start connecting them together with a little jumper wire and see what happens. Um, as long as you obey the, uh, safety stuff that we talked about batteries, only things like that. So look for more stuff in your life to two. Ah, pull apart and circuit Ben and make cool sounds out of There's a whole art to this. Look around online. You'll find people all over the place circuit bending really cool stuff. Remember I said, Ah, very early on. I think in the second video guitar effects pedals are great for circuit bending. You can actually, here is like if you want to go pro with this, what you could do is you can circuit Ben effects pedals together so like you would connect some circuit inside one of them to another one, and you could make some insane effects that way. There's some really cool people that I know doing a lot of really cool performances with the's multi bent pedals. So check some of those out. Just Google around for that, you'll be able to find it. Okay, so that's all. Check out some of the other classes. If you had a good time, leave me a good review. I appreciate it. Otherwise, I will see you in the next class. Uh, have fun breaking your toys. My 21. SkillshareFinalLectureV2: Hey, everyone want to learn more about what I'm up to?
