 Hello, hello. Hello, everybody. Welcome back to show and tell This is by me and Pedro. This is the eight of us young tell this is the best way to show off your awesome DIY project Rather, it'd be through your printing or electronics piece of bees Up your workspace everything is game Go ahead and jump over to discord at gg slash eat a fruit. We want to show off your awesome project We're gonna start off with some digi-key folks and a jump over to the eat a fruit folks And then close it out with some peeps in the community take about two minutes Uh reminder there is no uh asking engineer tonight. That would be next week and uh, there was no 3d hangouts either That's what we're doing this But uh real quick wanted to show what we're prototyping because we didn't have one and it seems to be a light trial today So real quick. This is what i'm prototyping. It is the Super cute little lola bot from obi-wan kanobi This is uh, I guess like the companion drone. It sounds like they make the Toys and then like write a whole script for whatever Right, dude. Okay season's gonna be so It's a it's a bit CRP 2040 inside here You got like all the cool ports in there and then of course you have like the magnets on the Side there so you can have like some shoulder mounted little uh for a little about So that's when we're gonna have a big release next week Of course with all the CAD files and all that cool stuff. You've got a little owl that will be like a Remote control. Yeah, let's quickly share. Uh, I needed a tv remote So we fit or lamar had the idea of making the tv remote into the shape of an owl So we have the ii leds as the i we have a receiver right here too so we can sniff the the Stuff from the remote and then we're trying to clone and then an arcade button Uh for whatever you want to do whether you want to turn it up turn off the tv turn it on Through some volume you can kind of pick whatever Thing you want to do and because the freaking kids always lose the remote. Yeah, she's like digging in the couch So we just lost my little problem saw her right there. So okay. That's our little show of talent Let's go ahead and jump into uh, did you key jay? Okay, here we go jay. What's up? Hey jay Good. I love that. Oh, I'm looking at cool antenna It's having a ball right now. Give me a second Sorry, it still has the mixture recognition problems or working early problems, but I attached the process into it now So when it sees the face I actually play a a note But it's keep looking into the corner here where I have like my face and other stuff over there So it kept playing on and off and it was just getting getting to me for a second I gotta change the voice lines for them. But this is my first zero two This is uh, going to be my new travel robot. So when I go to events and stuff I can bring this guy with me and walk around and get more interactions and stuff since actually interacts a lot better than the original Especially a lot more hyper too. I don't know what I did on that one, but yeah So cool and this is going to be released soon on the digickey's site Uh, we're hoping to get stuff done for it soon, but we're still we'll see we'll see we'll see Okay, awesome. I'll be uh waited. Oh, that's so cool And uh any other stuff I know that's just it No, that's a great update. I love it. Yeah. All right, cool. Thanks for stopping by jay No problem. All right, jay. We'll check in with you next time All right, go ahead and check out what uh, john's doing John park So, uh, I am setting up some stuff here on screen if you want to switch over i'll show Um, unfortunately, I have a little bit of a black hole just because I kind of wanted to look straight at you guys So I share my whole time including that there. Um So actually listen, I worked together on a guide where we did a couple of variations on uh, cassette player hacks And the one that I did uses midi through a little cutie pie here And a DAC board these are quad DAC board Which then is sending out voltage to the wiper of the speed controller of this little g e Uh, general electric walk man is a really popular one for hacking because it actually does have Uh, a little minimal speed controller on there was meant for like dictation So you could slow down or speed up your dictation when you're playing it back presumably Um, but it's a really good one to hack both with just straight up potentiometers Uh to doing control voltage or in this case midi to control voltage And so I just wanted to show a demo that maybe is um Clear because it's all on one screen. I'm not using my midi keyboard or an outboard sequencer in this case I'm just using a piece of software here. So I've got vcv rack, which is this sort of virtual modular And I have on it a little virtual keyboard and you can see over on the left There's a scope there showing the voltage That those key notes are sending out So the funny thing about this is that we're using sort of virtual voltage And then I'm converting that through a module that turns it into midi And then that midi as you can see the output there My choice is qt pi rp 2040 circuit python usb midi port zero, which is what's running down there on the tape deck So every time I hit one of these notes, it sends a different midi note to the Qt pi which then converts that back to voltage. So really we're working in voltage the whole time Just have a little trip in the middle So what I've got on here is a a tape that I made a little continuous tone on actually half of it is a continuous tone The other half of the tape is a little tritone sort of slightly detuned sine wave tritone So when I play this back, you'll hear it playing a particular pitch But then as I tell it different notes, uh, it's going to change that. So here's a little demo of that So you can hear it's not quite semi tones. Uh, it's it's smaller than that I didn't tune it uh to to exact semi tones because we only have a pretty limited range we can work with Uh, given how this this is set up with the speed controller Um, but it's a lot of fun because you can do not just playing notes like that but send it sequences, right? So I could I could set up, uh, I won't do it all in here right now But if I pick one of the many many sequencers that we have to work with here's a nice 16 step sequencer now I can send that output to it program all sequences or do Neat things like a Turing machine which gives you, uh, randomized Voltages that are repeatable with a little sort of shift register so we can send it Unquantized or quantized stuff you can make arpeggiation generative things So kind of any way you want to feed it midi doesn't just have to be a keyboard We can now get this player doing some neat stuff now Someone pointed out before this is actually a quad DAC. So you could set up four of these Little tape players for walk men next to each other and send the output from The four different DAC channels to that and now you've got polyphony you can play chords of the tape which is pretty cool So kind of a next level hack that people can do if they're interested So that guide is out and uh, if you want these are usually about 10 to 20 on ebay get one that's working otherwise you'll have to change out of belt Which isn't too hard and those are pretty cheap But it's a really great little hackable cassette player that I've had a lot of fun hacking This is an excellent jumping off point for uh, doing the quad like I'm imagining a cluster of tape decks Just Like all the people do like the what is the the pie clusters? I am a able cluster of tapes so you can get it like a 19 inch rack and just put The bazillion tapes in it like yeah Cool. What was the software you're using again? So I'm using vcv rack Which I think stands for virtual control voltage. So control voltage is what I was talking about for Vcv rack is great because it's free and open source There's a there is a paid version that has some features people who want to use it I think as a vst inside of their other dot We'll we'll pay for that. Um, I think I don't think I've paid for it I think I have paid for some modules, but most of the modules I use are free And and a lot of them are actually digital recreations of real-world modules. So Mutable instruments is a great example of that If you look at all of these ones with the magenta knobs, those are real-world modules that are super popular such as this this oscillator here This is a recreation of it. It happens to be a digital module in the real world So it's actually a fairly straightforward process of belief to port it into here But it allows you Learn about making modular synthesis without paying the money associated with real-world modular synthesis Which is kind of where all your spare money goes if you get into that as a hobby I can But the way this thing is working it really doesn't matter because any Use garage band. I think that'll output midi if I'm not sure Certainly any ios apps. So there's a bunch of really cool ios apps like Fugue machine which builds these really cool Sort of polyrhythmic chord patterns So you could send out chords if you're using the DAC method or Single notes if using just the single DAC and the single tick player But any way that you can generate midi plug it into this and off you go So it's kind of neat given how many cool software midi things there are and hardware midi things there are To be able to go into this And then the last thing that I that I would love to do at some point that I did none This is add a hardware midi input So you could use classic midi over like trs or get five And then you just power that but it would it would be pretty simple like about One line of code I think to say oh and let's also listen on you are for For for real midi classic midi to come in So the uh the learn guide is is public now so folks live and there's uh, there's actually two different Sections in there. You can check out the two different versions of this sort of thing that Liz and I both made so Go go and get your cassette on Cool. Yeah, let me check out the software. I definitely want to check it out. I thought it was like reason or something Yeah, you got the vibes reason too. All right. Totally. Yeah, I think they had what reason blocks is a similar modular thing That's okay more recent one. Um There's soft tube and a few other paid ones out there cherry audio as a cool modular But this one is super popular because it's free and it works just just kind of how you would expect it to so um, you can go and look at any Sort of lessons online courses on learning modular and use this as as the way to do it so Very cool. Cool. Oh, right. Thanks. Thanks. We're gonna check in with Liz. Nice. So we'll see uh part two of Excellent All right. Thanks. All right. Yep. I forgot I had this thing on. Oh, you get there. Okay All right, it's uh check in with us. Okay. Hey, hey, how's it going? Um, just go ahead and switch my camera um, so I did kind of the more chaotic uh tape hack. Um, where I Basically desoldered the actual motor wires, um that are on here and connected them up to an l9 1010 uh motor driver and then I'm using circuit python. Um, just use the aterfruit motor library to control the speed and direction of the cassette motor. Uh, so I can use it with a tape loop Um, and it will just continuously play either forwards or backwards and I'm controlling that with this pot So when I'm all the way over here, I'm going full speed forward And then it'll taper off and then when I go all the way over here It's full speed in reverse. Uh, and then I've got this button here when I hold it down It'll kind of do this rev up like warble thing Um, because I think probably the coolest sound tape does is when you get that kind of like speed up thing And you're hearing a bit with john's hack. Um, when he'd play a note, um, you get kind of the ramp up to it So that was my version. Um, and what was cool is I was able to solder On the outside of the two battery terminals because it just takes through going through volts because it's two double A batteries So the cutie pie is powering the entire thing. So it's just this little kind of compact Thing, uh, and I went for the fisher price play school vibe, um with the colors and the Design because I did have those either fisher price or play school like a primary colored cassette deck when I was little Um, so I was trying to emulate that So yeah, the guide is live now Well done. Yeah, I like the choice of colors even in the wires. They're very excellent. I like the knob too Yeah, the support free printing knob Yes. Yeah prints flat this way, but you should Fun very cool Crank it up. Awesome Um, sweet. You also have a um, did a video on, uh, creating your loops too, which folks we check out Yeah, yeah, um, it's surprisingly easy to make your own tape loops Yes, that's awesome. I had no idea it existed. Yeah, that looks so cool. That's so cool. All right. Awesome. Thanks for this stuff Thanks for sharing it with us and uh, we'll check in next time. All right. Hey All right, let's go ahead and jump into the community. We'll start it off with, uh, mark Did we want to end it with mark? Oh, uh, I guess john. Yeah, mark is special for us Hey, John. Hey John, welcome to the show. Okay, I'm unmuted now. Hey guys So I just wanted to show off an idea that my dad had this week and I helped him turn into a project Um, so at his work, he's been spending a lot of time finding where plugs are in relation to like their circuits in a house, right? We're driving him crazy and uh, we came up with this random idea to use some little wi-fi Notem to use right? Um, so basically the idea is right you plug one into the the socket you want to find out You come over here switch panel with your other one that's working And then if you turn it off it'll show you that that is uh disconnected, right? So they're just talking to each other over wi-fi Um, so I've got this one hooked up in the other room and then uh, this is the one that's with me on my laptop So I come over here And I flip this off My turn's off and you found this the the the socket that goes with that uh that circuit So nice Anyway, it's just a simple project. My dad's supposed to be trying it out sometime this week. So I'll let everybody know Yeah, let us know how it goes. Yeah, cool. That's awesome. I think we need one of those Yeah, like the liturations came by and labeled nothing. It's like What the heck? Is it on or off as we're yelling Oh, man, that's great. It's so great. Thanks so much John. Yeah, that's how it works. Okay Thanks. Thank you. Take it easy. Thank you like two of those All right, let's uh end it off with a mark. All right mark the show I I totally need one of those because yeah, my electrical box is completely unlabeled. There's space there. Why didn't they? Yeah, they have a little space Yeah So, uh, it was last week. I picked up some of these small circular displays that I've seen some people using and Like any good delivery it showed up just when it got kicked out of my house for home repairs for a week um So today I finally had a chance to play with them. Um And I realized initially there were going to be for the heads up display I'd been working on but like any good maker got distracted and decided to do something else so I hooked up accelerometer and to the display And then started making something where the little ball will jump around Yeah, and this is has an idea for a bigger project So today it was just sort of the proof of concept that it would actually work Yeah, this is a it's fantastic. Uh, I've got so many project ideas All right, this one simple circle inside of another circle. Yeah, there's still some math to do. Um Because it's doing stuff like getting stuck on the wall at weird angles, but It's behaving though. How you would expect though Yeah, for the most part it looks, uh It looks like it's in liquid Like there's some displacement. Yeah. Yeah, it's like some liquid inside of it or something Right. So I'm like, yeah, I like it So yeah, it's been it's been a lot of fun Sorry, uh, I'm thinking somebody designed some 3d glasses that I That I've seen online and then I think this might work well on there Oh man, please post the link to these these are great. Yeah. Yeah, no for sure. I will it's uh Just a start and I'll see where it goes from here and I love these little circular displays. So they're Yeah, I've always I want one so bad now. Oh Just the shape of it like Yeah, I have to think, uh, Todd bought had some good examples that I copied and also For this code paint your dragon also had it running on a Halloween m4, but with a square screen So the circle actually makes it easier for the math thankfully because I'm not very good at it I I could not do Awesome. Yeah, please come by Great progress. Share the link share the progress So cool. Oh, I'm inspired now This is why we do this. So cool. Thanks so much Mark. Yeah, for sure. I'll be back when I've got more with it Cool. All right. Thanks. All right, and I I think that's uh, gonna be it Okay, well Turn in to show it Next week, uh, we'll which will be hosted by the Montville Yes, and the return of ask engineer and we'll be back to uh, be showing off all the stuff and yeah Remember to follow us on all the socials And uh, check out the discord at discord that gg slash either for any more updates Yeah, there's still some shows going on, uh, throughout the week though. I think, uh, JP have a show tomorrow He's got an on his head. Yes. Yes He gives a thumbs up and then uh, potentially foamy guy for a friday stream. We'll see yeah, and I think uh, they're doing some recordings for ion mpi and uh Uh, geez. I forgot the other one There'll be more stuff. So just tune in to the shows socials. I know great search. There you go. That's what it was All right, folks. Well, that has been very fun. Thank you everybody I'll participants for showing off your stuff and inspiring everybody We uh, we'll check you guys out uh next time. So then remember to Make a great day. Great night. Yeah See you next week. Bye folks
