 Hello, and welcome to the Adafruit show and tell. I'm Liz, I'm gonna be your host this evening. If you would like to join the stream, show your project, you can find a link in the live broadcast chat on our Discord server, and that's at adafruit.it slash discord. So we're gonna kick things off with some folks from Adafruit, and then we'll hear from people in the community. So first, we'll go to our friend Jepler. How are you? Hi, I'm doing well. The first thing that I wanna show you is, last week I was on with the Metro M7 from Adafruit. This is still the green pre-release version, but this week I've changed some stuff up. It's still audio, but it's connected to a different peripheral that provides P2OM audio output. And this is a do as I say, not as I do. You shouldn't have the speaker directly hooked up like this, but it works good for testing. And the other thing is I've got an SD card and tonight that's where my samples are stored. So if you give me a second here, I'll put this back on the desk, plug it in, and we will hear some samples I found in the Adafruit LINE system. Excellent. And I was using the audio stuff today that you implemented is working quite nicely with Metro M7. You were kind enough to start on the guide pages for that and everything. And the audio is not starting. Well, that's fun. Oh, the live demo gremlins have arrived. Live demo gremlins. And the PD, oh, here we go. There we go. This is for ZYPUS. So these are just some audio samples I found in the learning system. And so this is playing with the audio mixer. And I found that I can go up to at least four voices at once. So this will turn into just like a whole, complete jumble. But that's playing four different audio samples, all at 22 kilohertz from the SD card. So you can mix audio in real time, like from different files. And it should give some latitude to do something that we can do on our other platform. So anyway, that's mostly what I wanted to show this code, both for enabling the speaker, both for enabling the version that doesn't need the I2S chip, because what I showed last week goes, whoa. Okay, that's just gone now. Goes through this board here, which is an I2S decoder and amplifier. And instead it comes out as a PWM signal that a small speaker or a headphones can do directly, or you can connect it to like an amplifier, just a regular analog amplifier. And it really works quite well. They are a little deprecating. They call it medium quality sound in the manual, but it sounds of all of our PWM audio outs. It sounds just about the best from my experience so far. So I hope you'll pick up that next beta when it comes out and try this out on your Metro M7 with SergerPython. Awesome, thanks so much, Jeff. All right, see you later. And next we are gonna hear from John Park. Hey, John. Hmm, my camera just decided to stop being a camera. Let's see, hold on. Yes, you are a disembodied circle. Would you like me to come back to you? Ron, hey, it's picking a funny camera. Hold on one second. I think I can convince it to go back to, oh, that's funny. No, it's decided my FaceTime camera doesn't exist. You know what, I can just talk as a disembodied orb, which is kind of the point here actually. So what I'm showing here is a game from, gosh, I never even looked up the date, but it seems like it's probably, I don't know, I'm gonna guess 1979 or so. It's a game called Computer Perfection. And it comes in this just spectacular ashtray from the future, retro future looking thing, kind of like a space helmet. They love orbs for that one. Orbs are great. And this is from Lakeside, Lakeside Learning I think. It's based very loosely, I think, on a game called Perfection that was just a kind of plastic spring-loaded mechanism on a timer game also from the 70s where you had little shapes. I did play that. Yeah, right, and they'd pop out at the end, so you had to race to put these little shapes that were sort of like these in place. So this is just only very loosely based on that. It's a buttons and LEDs game. Let's see, it may have decided it doesn't wanna start now. I've got it kind of mostly disassembled, but when it works, and that part actually doesn't really matter, you basically have these what, 10 buttons to press? Okay, it's starting to do some stuff. And you're supposed to figure out some sort of mastermind-like pattern. I have it in its test mode where it just lights up each LED as you press these. There's also a speaker, which I've disconnected as I've been taking it apart. But Phil P.T. Filtrone found an image of this online and said, hey man, this thing looks like it could really make for a neat synthesizer. So I got one on eBay, pretty cheap, 20-something bucks. And I started taking it apart. And actually, the part I'm most excited about so far is I unscrewed these two screws that were here. And that's all you need to do to get to the circuit board, which just kind of pivots beautifully open for you there. So it's got, I've taken over, there was a hinge-based switch here. When you open the orb is what it turns it on. I've disconnected that for now just thrown in my own little slide switch so I can turn it on and off. But there's the circuit board. I have started diagramming it and figuring out how it works. I'll go into way more detail tomorrow on my show, I think, especially if I can get it doing something tonight. But the idea is mostly gonna be to take over these buttons and switches, maybe add an amplifier and speaker into the base or on the inside there and turn it into a synthesizer probably using the Metro M7 or possibly an M4 but Jeff and I are gonna take a look at the possibility of doing some synthesis on the M7 which could be a lot of fun. And that'll mean I have a bunch of buttons to press and some switches to change parameters or patches or modulation. And so this is really just gonna be a platform for that experimentation. So there's computer perfection. Yes, that's so great. I'm really looking forward to this and you and Jeff's team up. And I really enjoyed all these tear down music hacking things you've been doing recently. Oh, thank you. Yeah, it's been a lot of fun. There's a lot of it. It's interesting, actually one of the things I'll show tomorrow that I'm excited about this is a lot of the modern stuff like the Meowzix. They use the same sort of little conductive pill under a silicone or a laster button to close some contacts. This one's got springy like leaf switches. Like it's real metal switches and so you can actually run some current over there. I think the LEDs actually in some cases light up just cause you're pressing the switch. It's not the microcontroller or anything doing. It's real switches. So that's kind of a change and same with these. There's some nice multi-position switches here. That's awesome. All right. Well, thanks so much, JP. Thank you. And we're looking forward to seeing your show tomorrow. Come on by, thanks. All right, now we're gonna hear from some folks in the community. We're gonna kick things off with Si. Hi. Hey, how are ya? Good, good. So a couple of weeks ago, Lady Edda actually showed off a iron 100 beacon in the NPI segment. It really piqued my interest. So I used that beacon chip. So it's a beacon, a Bluetooth beacon that could be used to connect sensors to it. So I designed a soil sensor that's in the shape of Daisy. So what I did was I took the Stemma sensor design, took all of the components of it, just kept the soil sensing aspect of it, added some two leaves to it, and I designed this board that could be basically powered off of a coin cell. And there is also the option of using the photo cell to power the entire system. It basically consumes about, like it needs an input voltage of about 1.8 volts. The board is working. I still have to figure out what's its power consumption. Can it actually run off of a photo cell? I know that the photo cell is generating the voltage. I'm really proud that it actually worked in the first attempt. I'm able to like look at the data using my phone, yeah. That's awesome. And so do you have these files available for folks to make their own or are you gonna be selling them on Tindy or? It's on GitHub. I'm yet to finish documenting my project. I have to still profile the current consumption and all that, but I plan to publish the, like the designs is already on GitHub, but I plan to like carefully document it on Hackster or something like that. Excellent, great. Well, feel free to drop the GitHub link in the Discord so folks can watch your progress. This is this really cool project. Awesome, thank you. Awesome, have a good night. And next we're gonna hear from DJ Devon. Hello Liz, how are you doing? Good, how are you? Okay, I have a 14 segment project. Excellent. Let me hit save here on Mu. And now it is, the computer has a batch script that goes out to an API and grabs a file that has like 18,000 lines of code in it, a CSV file. So we're talking this massive, massive file. The microcontroller itself parses the data, not the PC. So, and then it shows like how many lines it just parsed. Very cool. So the S2 with its mega awesome amounts of RAM can parse that many rows of data, not just like little bits of rows of data from a CSV directly on the microcontroller, and that was a project. And then another project is this new board that I made which was opposed to, it doesn't work. Just right out of the bat doesn't work. It's okay. It was supposed to have an Adafruit Feather, a Raspberry Pi Pico and a BFF. So any project that you want, you could put on to either one of these slots and then work with it. And it's specifically designed for the Adafruit I2S amplifier. Oh, that's really cool. So it's just for audio, little audio projects. So the amplifier is supposed to go out to the audio jack via jumper wires, but it just, I just can't, I can't get it to go past the amplifier. Yeah. Well, that's all right. I'm sure you'll get that. Yeah, it's a work in progress. I just built this like a couple hours ago, so. Okay, yeah. We'll see if I can- That's really handy. I mean, I know when I do the product guides, there's certain examples we always have to run. So I like the idea of having a board where you can plug in all the different format boards and it's going right to the breakout. So that's really cool. Yeah, and every single one has an additional side GPIO on each side, even including five volts, out for the QDPI. There's a ground bus, a 3V3, and someone posted up in the hardware form that it was basically like a little mini dev board that I built, but that wasn't the reason. The reason was to stuff this in the mailbox to get rid of the spaghetti monster in the mailbox. Okay. So that's the goal for that one. All right, well, definitely keep coming back and sharing your progress on this, really cool. Thank you very much. Have a great night. Have a good one. And next we're going to go to Mark Gambler. Hey, Mark. Hello. How's it going? Pretty good. Just getting my camera up. Okay. All right, so you might remember, and a few others in the community, about a year ago I showed up with a project for my birthday. Yes, I do remember. Two years ago I tried to make a fan to put out a candle in the midst of COVID. It did not work. It also did not light my house in fire, so I'll consider that a win. Last year I built a water pump that promptly flooded most of my desk area and the desk this is now sitting on. You still have it all. So I thought I'd take a much cleaner approach this year. With the animated gift code that I just did, I thought I will just have an animated cupcake on a fun house, which is the perfect form factor for this. And that you can now blow out. So the first thing I added to this, and I'm hoping this is going to play. Oops. Did we have a preemptive candle extinguished? Well, let's just relight it again. And that's the other bonus is it can. So it's just using a humidity sensor. I was probably too close in breathing on it. Okay. But then you just go. And there it goes. There we go. Awesome. And yeah, you can reset it as many times as you want. Without those match fumes, so that's great. Yeah. And I haven't flooded my house or lit it on fire. So I'm going to consider all that wins. I also had a slightly different mode. Sorry, it's copying files over to the fun house in the moment. Okay. There we go. Where in honor of last year, there's also where it will dump water on your cupcake and put it out as well. That's really funny. That's really cool. I like that every year you're building more on this. So. Yeah, it's been needed. Something to encourage me to keep going. Less destructive this year, so. That's good. All right. And the GIFIO stuff's really cool. I know folks have started to experiment with it, so thanks for adding that in. Yeah, I'm really happy people are using it. It's great to see people actually use what you've taken time to write. Yeah, it's a really good feeling. Well, thanks so much, Mark, and happy birthday. Thanks a lot. All right. And now we're going to go back to our friend Jepler to have him play. I think he needs to take that thing that you lower over the candle and like lower it with an RC servo. Oh, that would be. Next year, Mark. Next year, Mark, if you don't have any other ideas, you can have that one for free. So I got to do a second guide with OpenAI this week and it uses a 3D printing case. It's very similar to one Liz used in her PicoW project, but if you want to come to my overhead camera here, what I love about this project is it's just really easy to create your own prompts and change them out. So right now the prompt is make up and vividly describe an original imaginary and unconventional, but cute and charming monster and Flufflet. I mean, who does not want to meet Flufflet, the six-legged robot or rabbit koala who wants to cuddle and sleep in the sun? I'm a little hesitant to meet Flufflet, but I like its name. It's a little overwhelming, but yeah. And it just comes up with stuff and some of it is cute or some of it is funny. And then to edit it and change it, you just open your settings.toml file and I've got a bunch of different blocks that I can just enable. Okay. So this one is called pip install dash dash random and the task is make up a PyPI module that would be useful to a house pet. Use the following format and it explains the format that it wants. So this one kind of gets in a little bit of a rut because it doesn't know what pets want to do with computers, but it was worth a try. I think the most entertaining is the prompts you come up with are very creative. I really enjoyed that. Well, thank you. I spent an inordinate amount of time thinking about it. Definitely worth it. Yeah. And then I just always want to call out, French is kind of my second language. And if you write it a prompt in French, it will answer in kind. And I think that goes for a lot of world languages. And with this project, the font supports kind of most of those general European characters. Excellent. Yeah, I don't know what else I want to say about it, except it's a lot of fun. You can engage your own kind of creativity in coming up with the prompts, but it's also a basis for just incorporating chat GPT in a project. You get back the response kind of streaming. The first one got it in a chunk. This one gets it a little bit at a time, a token at a time. So it's also a little bit more advanced way to interact with chat GPT. I like how the light is almost like, almost feel like Morse code coming in as it. Yeah, a little bit. It's kind of, I wanted you to know it was thinking. Yeah. Thinking real hard. Very cool. And this guide is live now on the LearnSystem. This guide is live on the LearnSystem. So you can get that source code and put it with a Raspberry Pi, Pico W, running CircuitPython, a little OLED display. And you just have a little bit of wiring to do to hook up the arcade button. So it's really, as these things go, it is a pretty manageable project, although you do have a little soldering. But it's always fun to break out soldering. Yeah. All right. If you haven't, you should learn. Yes, definitely. Well, thank you so much, Jeff, for showing that one, but two awesome projects. All right, you got it. Have a good week. Have a good night. All right, and that's good to do it for tonight's show and tell. Thank you, everyone, for coming by and showing your projects in about 10 minutes. Right here, we'll be asking an engineer for PT and Lady Aida. So stay tuned for that. Until next time, have a good week, folks.
