 All right, Lady Aida, what is this? Hey, everybody, and welcome to Show and Tell. We've got a bunch of people from the Adafruit community and DigiKey coming by that are gonna show us what they're working on, hacking on, soldering and sewing and 3D printing and all that goodies. And we've also got people from the community who are gonna come by and you're welcome. You, yes, you. You've got a webcam and a mic. Well, come on by and show off what you're working on. It doesn't have to be done. It doesn't have to use Adafruit stuff. All kind of making our welcome. Even art and design and house play and. For the folks who watch our shows or always trying to push the envelope state of the art, we're working out a way to do camera stuff so we can do more show and tell stuff ourselves. So this is the result of the setup being set up for our hack chat today. So these are some key caps. So what we're hoping to do is have some more show and tell stuff from Lady Aida for myself, retro hardware and more. So this is just a little bit of a preview but without further ado. Okay. Kick it off. Kevin from DigiKey. What's going on this week? Hey, how's everybody doing? Good. Good. So speaking of key caps, there's a really good segue into my project. That's right. So I'm working with a macro pad and I'm creating my own keys. I have four different macro setups in here. And this one specifically, I'm a junkie for shortcut keys, keyboard shortcuts. So this thing is just, you guys were speaking my language when you created this. Yes. I have one on a Mac. One thing I hate is having a ton of windows open and how do you close them all without close, minimize. Minimize. So I found out it's like a four key sequence. I have it set up on minus W. So minimize windows. And then I have a screenshot. I have the sleep button. I'm not gonna push that or you guys will lose me. And I'm still working on creating the rest of them. I have the shortcuts created but I'm working on 3D printing the keys. But it's pretty cool. I have a, you know, you push a button and changes color. You probably can't see it. It's a little washed out. But I love this macro pad. This thing is just amazing. Yay. Yeah. We like looked at every macro pad and project and we tried to take a little bit of the best of all of them but also give it a little bit of an ate a fruit spin to it. I think we did, I think we did really good. I think this is a, does a little bit of everything. This one is just a simple 10 key is what I created for this one. But yeah, I absolutely love this thing. And I have another one of my teammates working on creating his own version of what would he use it for, without telling him what I'm using it for. So I'm curious to see what he does with that. Yeah. And a few projects ahead that we're going to show us. And the Olympics are coming up. So a lot of folks are like, how do I keep track of everything? And they're making their own macro pads that have all this, like when you, when you hit the thing in the sport that you're looking at, it'll, it'll bring it up. Yeah. There's so many things. The opportunities with this thing are endless. So you guys did a great job on it. I'm looking forward to playing with it more. I also love how easy it is to, to modify having, having seen the effort it takes to use, you know, KMK or QMK, I think this was, it's so easy that, you know, you can put together your own, you know, overlay macro setup, you know, in minutes, you know, an hour, no compiling in. Also, if you work at DigiKey, you have to like key stuff, like keys and the name. DigiKey is digital. It's a, it's a, yeah, it's a requirement. It's not called, it's not DigiMouse. Is that why you created this? Because of DigiKey? Yeah. Okay, good. Okay. All right, thanks a lot guys. You're a trademark lawyer, so talk to our trademark lawyer. Okay. All right, bye Kevin. Thank you. All right, take care. All right, next up. I'm Pedro. What's extra in this week? Hey guys. Hey folks. We've got a macro pad project as well. We're going to lean over to the accessibility part of this though. So Braille key caps that you could 3D print. It's got like the most, I think the most common type of keys you might want to have on here. So it's volume up, volume down, page up, page down, copy, tab to move through different things. But not only that, you also get audio feedback. So hopefully it doesn't get any, move any of the windows here, but you kind of hear the little speaker on there. Yeah. So you can tell the difference. Yes. If you're like learning Braille, you get that extra layer of feedback in addition to- I often think it's like maybe it tells you actually did it or cause you know, if you have overlays, the overload might change. But I thought like, even though it's just a tone, I always like having speakers on our design. So it's not just visual. You can always have audio feedback. I respond better to audio than visual feedback. Yeah. I think it's harder to use like a virtual keyboard unless you can hear a clack, clack, clack. Yeah, yeah. You know, like this is like good, making accessible things just makes better products and better designs anyways. So this is a good exercise. Yeah. And hopefully we're gonna get, you know, wave playback work in Phoenix, fixed up soon. And then you can of course play little audio clips too. That'll be fine. Definitely, it'll be a nice little sound board. Super cool. So we just use like, you know, the standard Braille Alphabet on there and some of the special keys to create all these. And then on 3D Hangouts earlier today, we showed how to go inside of the Fusion file and actually make all of your own custom keys. So if you check that out, and of course the guide and all the files are out and available for this. And Katnie did the code for this, posted that up earlier today. So come check it out and make your own keycaps. A great power up team up. Nice work. All right. Thanks so much. We'll be showing, we'll be showing your videos tonight. And you have a fun speed up. We have a Loki. Oh yeah. This is a Loki Gator? Yeah, that's right. That's my request. Thank you. Oh, he did do a power up. He's so cute. Oh yeah, wait. Hold up, hold up, hold up. He's so cute. That's good. Everybody likes Loki. I just wanna come on. Okay, I'll see you later. Next up, Scott, what you got going on, Scott? Hello. I just wanted to do like a cricket plug for the release that Dan just did, Circuit Python Alpha 5. And for those of you I just got one of these. I think I got it from DigiKey. This is the Arduino Nano RP2040 Nano Connect or whatever order they're in. Shout out to BlitzCityDIY who made the Circuit Python board definition. Unfortunately, the flash chip they have on there doesn't actually tell us what size it is. And so it was falling back to the default size. So if you have one of these and it has a one megabyte file system on it, in Alpha 5 I just fixed it, got it in today. But if you have one of these, back up all your files and then do the import storage, storage.erase file system, and you should get the 15 megabyte file system after that. So that's one of the many fixes that went into Alpha 5 we're like trying to buckle down and get all the way out to 7.0 stable. So keep an eye on that. All right. I'm so excited. And deep dive this week, right? Deep dive this week. And thanks to Jim for joining last week's deep dive. One of the MicroPython developers went deeper than we've ever gone on a deep dive right down to x86 assembly. So it's very cool, Jim is awesome and Xemian is awesome as well. So thanks again to Jim for being on that and check that out. It's not just the same old, same old last week at least. I love this 7.0 release. So much good stuff is in it. I love that we're catching up and starting to contribute a lot more code back to MicroPython. It's easier to do cross property contributions. A great merge has happened. So cool. Yeah, it's fun. And that just reminded me, I have to email all of the MicroPython folks will probably do another team meeting with them as well, which has been really fun. It's so weird to like, it felt like a team at work where it's like, oh, these people work in the same code as we do and think about the same thing. So it's great to be working closer with them. Neat. This is like the open source software and hardware dream. Isn't it? I think so. At least I'm living the dream. Well, I think with open source projects, people, they're aware of like forks and they're aware of like, you know, name changes. Like there's a lot of things that happen in news, but you don't hear about the success stories of doing open source with a bunch of people, maybe not all at the same time, but I think this is a good example. Like there's different goals for the different projects, but there's a shared code base and like a shared desire and values and goals. And it's all starting to come together, took a while, but here we are. And if folks are interested in that, I'll plug the talk Python to me episode that I just did with Damian as well. So that's really interesting for those who are interested in this dynamic between circuit Python and micro Python, check that out as well. We're gonna have that in our Python on hardware segment on Ask an Engineer, which was in the newsletter, which he's signed up for on A to For Gamer, by the way. All right, thank you so much. Next up, Jeff Epler. What's your name, Jeff? Hi, so like a lot of people, I was intimidated by this 30 key monstrosity. So I don't even know what I'm gonna do with it yet, but what I did do was create this 3D printable kind of backbone that supports a feather and the macro pad itself so that you don't accidentally snap it apart and you can set the whole thing on your desk. Quantum computer? Yeah, sure, it's a quantum computer. It's, you know, running rainbows as you do. That was easy enough. But yeah, so I dropped the 3D printable files in the Discord if you're interested in making one. You just need to add some of the M2.5 heat set inserts and use some screws to fasten everything on and then it's nice and stable. And yeah, as soon as I figure out what to do with that, I'll actually do something. So ideas welcome. Someone had mentioned that the macro pad looks like the computer from Quantum Leap. Quantum Leap? Sure. And then no made me watch Quantum Leap, which was actually pretty good. You missed it, huh? Yeah, it was just a long age. We're not gonna watch all of them, they're long. I'll tell you though, I really loved Airwolf. Airwolf as a kid. That was like the weird kind of tacky issue. Yeah, all right, I'm getting insights here. But your project looks like if, you know, people of Ziggy kept going, like this is Zig Max, Ziggy Pro, Ziggy Xtreme. I feel like this is making me think of something from Star Wars, but I'm not sure exactly what is the white and red. It's the red. It's like Vader Plate. It looks like a 70's computer. Yeah, it could also be the Buck Rogers style stuff too. Anyways, you're talking about all of that. All right, thank you. I think somebody should definitely make it like a Darth Vader costume, but like his chest plates a synth and he can go in the movie. Play Darth Vader, yes. I'm worried that this has already been done. Probably. It's like when you Google for something it's like it's already been done. There's whatever's after rule 34, which is here's a cosplay that has been done at DragonCon. All right, well thanks Jeff. All right, thanks Jeff. See you later. All right, next step. All right, Tim. What you got going on? Hello. All right, so my project actually is inspired by Jeff's project from last week. Jeff showed off the calculator that he has been working on. And this is kind of an opposite take on that. So it will give you math problems and it's your job to solve them. So it will print out the problem there. And if you get it correct then it will give you a nice green sweeping animation. And if you get it incorrect then it will give you a red sweeping animation. And then I also built in some settings so you can turn on and off the different types of problems and you can change the numbers. So you can kind of make it easier or harder based on what your level of math is. And then I'm working on 3D printing the caps. These are the same caps that were in Jeff's calculator but I'm experimenting with dropping like nail polish and maybe paint or something like that in there to make the contrasting colors instead of different colored prints. I like that look. It reminds me a little bit of like, we know when I saw people etch acrylic with a laser cutter and then you sharpie over and then you wipe away the sharpie and it leaves like a very nice etch. You know, it looks really good because the paint is kind of embedded inside but that's, I really like that eight. Yeah. That's a fancy eight. So that's cool. Thank you. All right, nice work. This is really good. Thank you. Yeah, the thing that's- Can you sand 3D prints? Like, could you paint it and then sand away? Yeah, you can do that all the time, yeah. All right, that's gonna be a lot of work. Yeah, this is neat because one of the goals is to have a whole series of things that people can build and now we're up to like calculator. Yeah. Make your own keyboard, make your own phone, make your own camera. Yeah. Stuff like that. All right, Tim, well, thank you so much. Nice work. Thank you. Yep. Next, Andy, how is it going? Andy, what you got going on this week? Hey, I've got a device I made called Unitron and it's for doing live conversions between units. It's a keypad with a display. It's keypad nine. And so if you turn it on, so right now it's on inches and millimeters and so the top, the blinking is the input and so you can switch the input by toggling the switch. Oh yeah. So I can do like 20, this sort of do. Oh, this is cool. This is a good idea. 26 inches is 548 millimeters but if I wanted to do millimeters inches, I just switch it real quickly and then I can do feet and meters, miles, kilometers, pounds, kilograms, Fahrenheit and Celsius. That's cool. Yeah, and then it's powered by triple A batteries. Now that it's on the back, so you can put it on the fridge when you're always trying to get between inches and millimeters in the kitchen. Yeah. Common. I like your little sub plate for the display. Yeah, thank you. That's cool. All right. I kind of wonder. So it's kind of got a little bit of that steampunk thing. It's just like, and here is my contraption. It won't convert any units to any units. This is a very American problem with a very American solution. This is a very, we can talk about problems. Good work. Nice work, Professor Enny. All right, thank you so much, Enny. All right, next up we're gonna go to Seth and then we're gonna go to Joey. Hey Seth. Seth, what's going on? Hey, look at my son here too. So. Oh, fellow engineer. I have been experimenting with cords like crazy and I made this little matrix board. I don't know what that went on. And I thought, oh, microcontroller would make it cool too. And so why not add Wi-Fi? So I added a ESP32 S2 on it, a STEMA port. And so right now I've got the MPU 6050 on it and I thought it would be cool to make like a little like motion detector. So it starts up and then it gets going. So it'll, depending on the value it gets from the first bit from the MPU, it'll change colors. That's awesome. So it'll cycle between like purple, orange and green. So that's pretty cool. There you go. Yeah. And so I thought it was a pretty cool take on the matrices. I know that you guys have the matrix portal and I thought, oh, what if it was a little bit smaller? So. Yeah. I like the miniature versions of some of the kind of intimidating like here's a giant panel that's gonna bring your retinas out but there's a little one that doesn't do the same thing. Yeah, only a little bit. Yeah. So I was running on like 0.1 brightness. So I can imagine running it on half brightness. Yeah. So yeah, that was a fun little thing I was working on. All right. Well, thank you so much, Seth. Next up, Joey. Hey, Joey. I'm seeing a bit. How are you? I'm doing well. See y'all too. So I've been working on a, well, the watch that y'all I've brought by a couple of times and I reached the point where, let me see if I can share my screen here. Is that sure? Yeah. It's on its way. Cool. So yeah, so I've gotten the watch to the point now where I can actually start to like write some decent firmware for it and I'm actually using this PyQuarter gadget that I came up with while back or brought to the show a while back to display a UART coming from the watch. So now as I'm writing my iSquared seed driver, I can hit reset here and see the results of reading a devalue off of this sensor that I have chained through the PyQuarter, the watch. It's still like very early days but I'm very excited to finally be getting iSquared seed stuff working because it gets really cool once we have these little sensory gadgets. This is a BME280 on a flex board that I'm going to want to put in here and have on the wrist, just measuring temperature and pressure and humidity. Oh, that's a flat SEMAQT, it's very cute. It's very small, it's all pretty tiny. But yeah, I just wanted to buy and share I thought it was really cool being able to kind of use the SEMAQT format plus this other thing to, you know, yeah, just kind of build the tools to work on the thing, you know. So, Tiny, all right, thank you, Joey, always making cool hardware. And at some point I have this, so my to-dos are like sometimes in my inbox and then sometimes they're in my drafts and then sometimes they're in, you know, where I keep track of all the stuff. Make the e-book, make your book is still in there, so we're still going to make it, I just don't know when. Totally, it's just been a strange year for a lot of us. You're back on the East Coast now, right? I am, yeah. Okay, great, so we're here, we'll figure it out. Yeah, now's a good time to redesign, because of course now there's a silicon shortage, so just, you might want to design it for a chip that's available. I actually made it, I made a PiPico version, which is not feather compatible, but I'm also like brainstorming an ESP32 S2 version that would be feather compatible, so. Yeah, ESP32 S2, it seems to me we can kind of get them in the RP24, you can kind of get them. I'll say the SAMD51s, I'm not getting any for like a year and a half. Yeah, that seems like a... And we want to finish this within another year or two, but it's easy to redesign it because it went circuit Python or Arduino. You're going to swap out a different chip, so that's some hints for you. I mean, I can't predict the market, but right now those are the two things I seem to be able to get. Right on, good to know. Spin that up, we'll be able to... Definitely do not use an STM chip at all. If anything with STM in it, you can't get them. We will not get access to them. Well, thanks for the pointers, y'all. Thanks for having me. All right, thanks Joey. All right. All right, everybody, that was our show until for the week this week. Thank you so much for being part of it. This is the best happened ever. Live is pretty much every single week. Yeah, it's fun seeing people, friends, come by. Come on by. Every single week, 7.30 PM Eastern time. Ask an engineer, starts in about 10 minutes or so. See you all next week. Live, ready? See you in 10 minutes.
