 And we're back. Hey, Lady Aida, what's this? Hey, everybody, and welcome to Show and Tell, a new special edition. We're trying on some new broadcasting. Well, we have a different location. We're not the Aida Food Factory because we have to take care of a kid now. So we're in our tiny New York City apartment, but you can't tell. Well, it's not that much bigger than the screen, by the way. Like our bed is behind the double gear, and this is my closet at the end. But it's me, Lady Aida, with me, Mr. Lady Aida, and in the background somewhere is Baby Aida. But right now, it's time for Show and Tell. Well, first of all, I want to say thank you to all the Aida Fruit team members who are co-hosting and hosting the Show and Tell. We're still going to rotate some of the team members. Make-up Melissa is going to help us on this one. We're going to bring Melissa on in a second because we might have to bounce really fast, we'll say. And for everyone who's been just keeping an eye on Aida Fruit, helping us out, doing things over the last couple of weeks, we very much appreciate it. We're looking forward to a fantastic New Year. This Lady Aida has been making tons of hardware. I get to see it all, and I'm like in the room now, looking at this pile of prototypes. So a lot of things. We'll show some of them. Yeah. So let me first up bring Melissa by. Hey, Melissa, thanks for being a co-host and everything. I'm no problem. We might have to run out fast. So if we hand you the keys to the Show and Tell car, gas it up when you're done. So before we bring some folks on, what are you working on right now? I'm actually working on the sickofpython.org site and adding the ability to just kind of go through a little install wizard and install sickofpython on your board directly on there for like the ESP32 boards. So using like a web tool that you pick, you navigate to your board and then you say install and it goes? Yeah, like I'm taking the code that I done from the web serial ESP tool and kind of integrating that in so that somebody can easily just install it without having to go through a process. Because for like the ESP32, it's a little bit more involved since you have to kind of go through the ripple to generate like a Wi-Fi settings. That's cool. The ability to put the right firmware on a board has been hard. It's kind of like remember back in the day when you get like a laptop or something and you'd go to like the Dell support site and you'd have this like thing and you can never get the drivers for your printer. You can never. Reminds me of that. Oh, you wanted the ethernet driver for the FL38621, but you downloaded the FL38624 and now your motherboard IRQ is screwed up and like, yeah, just erase everything and start over. That's what it's like with mega controllers. And we look around. We were like, how hard is it for people to get the right firmware on their devices? It's really hard, especially if you have like more than one board. Even that's hard. OK, that's cool. Looking forward to it. Where will folks see the first glimpse of this? I had kind of come up with an iteration today, but based on some feedback, I'm working on redesigning it a little bit here. So hopefully sometime in like the next week, they can start seeing something. OK, and I'll probably put in a newsletter for folks to try out and we'll probably be a blog post and more. All right, thanks so much. OK, Jeff, let's stick around. Jeff, what you got going on? Well, this is something that is really easy, really simple, but you have to actually do it. So I just wanted to share how excited I am that I finally got around to doing this. So I've got a KB2040 and a time of flight sensor here. So it's an I2C bus going over STEMAQT. And this isn't actually the one that I'm debugging. It's a different microcontroller. But I wanted to look at kind of the low level of the I2C bus in my logic analyzer. And I realized there's this connector here. Normally, I would get this out and I'd stick it on a breadboard and run some wires to hook it up to the logic analyzer. But I realized I can just use these. I can just make a custom plug-in 4 by 2 header using these guys from the store. And then this is a non-standard. It's the STEMAQT size, wrong colors, that came out to female headers. And so you just pop them out. And then you have an end that looks like this guy here. And then you stick them in the housing in the right way. You just need three out of the four wires because you're not sending power from here to here. And then it's super easy just to debug whichever I2C device and host that you want because it's just one more connection on your STEMAQT bus. And they always have two. And they always have two. So you can daisy chain them, although, yeah. You could get that one with five if you needed it that JP was showing. But yeah, I just feel like this is going to be a tool that I'm going to get out a lot and plug it in whenever I'm working with this stuff. And the next thing I want to do is I lost one of my probes. This is what the original manufacturer connection looked like I've misplaced one of them. And I'm like, wait, I can just make my replacement. The colors won't match what the user interface shows. But the housings and the wires are just really handy to build something up that is a little more self-contained. And the other thing was if you've got a hot air station, use it on your shrink tubing. Works real good. No dealing with gliders. Like I did, like somebody who didn't even think about it. No, that's just, that's like the old school hardcore way. But the right way to do it is to impact use a hot air station. So anyway, that's all I got. But I mean, for me, it's life changing. Hey. Just like the tired wire. The tired liar is wired, not it. Well, I didn't love that. That came out like really handy. It's true. Like every time I do that, I just go and see like, I yank out the probe things. And I'm like, and the clippy things, like they don't quite grab on this stuff. No, those things, I don't know. They don't like me either. Yeah. They're great for like, if you happen to have an SOIC chip, but anything else, they're like, or like male headers, or anything else is a little iffy. So I will be making a cable like that too. That is a good idea. Also, constantly debugging iSquared2 stuff. All right. All right, walk on. That's what I got. Great idea, yeah. Maybe like an iSpy one would be cool too. Yeah, how many pins does that mean? iSpy has like 17 pins. But the display itself doesn't have that many. Yeah. Right. You don't need to use all of them to interface with the spy. You could just use a few off the break-in. Yeah. You could use the, well, you'd want the eight channel. Yeah. I mean, this does have eight channels. You'd need to use both of the headers. Well, you know what else you could do, maybe, when you look at this Pico? I hope to be showing that off sometime soon. So yeah, you know, Scorpio has the power. All right. Well, this is, I feel like we're building up to it. All right. Yes, Scorpio. Y'all have a good night. OK, thanks. All right, thanks so much. Thank you. And happy new year. And that was your edition of Jet Packs. All right. Next up, we're going to go to Pedro. Pedro, happy new year. What's going on? Happy new year. I was supposed to be off, but hey, I can't miss your guys' spec comes back. We're supposed to be off too, but you know what are you going to do? Yeah, there it goes. Just wanted to do a quick sneak peek of next week's project. It is the Pico W running Whippersnapper. And it's just a nice little simple case that Brent requested. It is a wall-mounted case. So instead of doing like drilling into the wall, it just uses command hooks. So it's cool. You have access to the prototype area in the back. And you have space for two sensors. And then the little reset button on the side there. And a big old fillet for that. And then access to the SEMA and how to power it. A nice little case for that. And then no project this week, but we did upload the year-end review. So all of our favorite projects from last year and of course, we're going to show that on Ask an Engineer. Yeah, yeah. So my favorite one from last year, besides the iBook, because my wife doesn't want to give it up. She's using it right now. I think we posted it like two weeks ago. I think you guys saw it. So we printed the iBook thing with our case that we have in the shop. And then the other one is, of course, what just finally released. This isn't it. This is the one that we three printed. It's just a little Lola bot that was hyped up about. Yeah, and they just released it. So definitely like, oh, cool. Good thing I made my own. I didn't have to wait forever for that one. Yeah. Nice little sort of Python-powered little droid. Well, it's a real droid. You can actually program it. Where's the one from? No. Can we program it? I don't think you can. Someone asked me what Whippersnapper was, and I tried to give an analogy instead of like, because it's a no-code way to do IoT projects, which is like, even that sounds complicated. I know. But what I've said is, you know how you've always wanted to have something just like email you when there's a leak somewhere? Well, you can do that without any code. And you could just kind of put these two things together and it just does that. Because there's all these like little tiny things that there's not something that does it. And this does. And you could just do it kind of like Circuit Python when you plug in a board. It just shows up as USB. It's like, oh, like, it's that easy. We still want to make things easier. So I'm hoping the Whippersnapper with Pico gets a lot of folks making the IoT projects. Yeah, definitely. So yeah, that'll come out next week. Thank you so much and happy new year. Happy new year. All right, JP. Thanks for doing not only the show and tells, but ask a JP engineer or something. Sure, it was loads of fun. Thanks for letting me do weird stuff on a different night. It was entertaining. That's why you're here. All right, let's do some weird stuff. All right, so weird stuff. First of all, I showed this on my product of the week yesterday, but I just have to show it again because I'm so happy with the little hub for a little passive hub for hooking up your StemAQT quick stuff. And I made a funny little sort of standoff airplane of four sensors to plug into a QT pie here. And I kind of want to make a whole fleet of these things, a little armada of pluggable stuff. But this is, we've seen a few iterations of people doing, how do we get away from big bulky breadboards and or soldering and with these little quick and StemAQT connectors and the fairly standard form factors of these. We do have a pretty LEGO-y type of setup here that I'm excited about. And then the other thing I wanted to show you is this. So I built one of these. I don't know if you've seen these in your Instagram feed. I built one of these models. Wait, which screen do you want me to go to you or your overhead? The big screen share there would be good. This one? No. That's that one. Yeah, sorry, we were like, you're looking at it. Okay. So this is a model I built for my wife for Christmas. It's just a kit that has a bazillion little parts that you pop out that are laser cut. And we glue them together for about, they claim six to eight hours, but I think it was more like 40 hours. You make everything. Yeah, that was not a 16 hour project. Little books in here and everything. And they're really neat. They use some neat tricks to give them depth. There's like a little mirror in there. And it came out great, but it's meant to go on your bookshelf among books. So it's like a little secret place. That would be a secret, yeah. I think Jen Schachter kind of invented this idea with some laser cut models she did a while ago and posted on Instructables and some other places. But these are commercially available kits. They're not that expensive. It just is expensive in terms of your time. But it's got a little battery pack back here. And there's about three or four little LED lights. You can see one in the roof there. And I kind of want to improve the lighting in there and maybe allow it to be controlled on a timer, not have AA batteries that'll just die after a while and maybe do some little flickering and stuff. So that may be something I just do sort of as a fun, cool side project is fix the lighting. I wouldn't change anything else about it. It's a lovely little kit, but... That might actually be a good project. You know, we have those little Oh, six or three LEDs on wires, which could be good. Yeah. And that's kind of what this is designed for models or you could, if you wanted to have, I mean, it's kind of, it looks like a Victorianie house. So I don't think the nude lights would be good because that would be more of like... Only if there's like a steam pump experiment going on. Yeah, like Sherlock here joins the... Yeah. Hey, Sherlock, how'd it go? You do whatever you want. Yeah. Uh-oh. So anyway, that was... I'd been curious, I'd been seeing these things in my feed and I was like, you know what? That might be a fun thing to... I was really high from the paper glue for a long time there in November though, man. You ever get paper glue that's meant for paper projects because I guess it doesn't like seep through like Elmer's and man, that stuff was noxious. I really had to... I had to ventilate that stuff at my... And... Well, that's part of the fun. That's part of the Christmas magic. Do not let this tiny room take you out, JP. Hey, that's why it took so long. I was like moving at half glue speed. I don't know. Anyway. Dollhouse miniatures are same. Well, you know, we saw a lot of like Christmas displays that were like dollhouse miniature things, right? Miniatures are so fun. And I've never built a little pre-made kit like this before. I've... You have to love someone a lot to build it for them though because it's a lot. Yeah, this is... Those books. Every single one of those is like a little laser cut thing and a cut out piece of paper that you can wrap around and hold down. Oh, God. It's like a bazillion of those little books. But this is extremely cool. I mean, they're gonna have this forever. Yeah. Yeah, for sure. For sure. Okay. Maybe let's put a cutie pie in there and we'll make it like the lights turn on and off. What's neat is when you see this, you know, there's someone in Disney watching our show and telling them to like, oh, we can make a haunted mansion version of this. Oh, please do. Yeah. Right? Like, this is... Yeah, so whatever it is you're doing in the weekends. Don't say that because Cory, the doctor's gonna watch the show and they're gonna make JP build him one. You can eat little peppers, miniature peppers, ghost. Oh, that'll be cool. Oh, see? This is great. I would love to make some miniatures of some of those effects if they... There you go. There you go. Have your own little pocket of imagine here. All right. Now I know what I'm doing for 2023. I'm gonna do a little tiny like, you know, hall of presidents. Hello. Projection mapping stuff. Yeah. All right. Tiny, tiny stuff. It just took away 40 hours of your life. Now we know. Now we know where I'll be and what I'll be doing. All right. Come on soon. A bunch of tutorials from JP on the little tiny... All right. Well, thanks, JP. Happy New Year and thanks again for helping us out. You bet. Happy New Year, you guys. Yay. Congratulations again. Yay. Happy New Year. All right. All right. Is two, two, three puppy. Hello. How are you doing? How are you doing? So I have been hard at work on this, the eFidget. The LEDs are on. Let me fix that so it doesn't go crazy. It is the haptic feedback fidget spinner that I've been working on for, I don't know, since like September, August. And like I said, it's a fidget spinner, has vibration motors on the back. And... You want us to show your face more than the computer? Yeah, I think right now, yeah. So it's basically just a cool device to help you kind of let out your like distraction. I don't know, you know what I mean? And... What's the chip that's on there? Is there a chip? RP2040. Okay. And it actually just got an immersion to CircuitPython today. Oh. It's gonna be a CircuitPython board? Yes. Oh. Sorry, I can't talk. Yeah, I just added it to CircuitPython. Or I mean just merged in to CircuitPython. Right, yeah, that was awesome. We'll just ask you a question. So it looks like there's a battery in the center and then how do you spin it? There's three little six millimeter push buttons and you just press one of those and it wouldn't be very easy to see, but I mean, I'll do it anyways. And then you just, like the motors make it vibrate around? Yeah, there's eight of them and they go on and off in a circle. That's really nice and tactile. Yeah. Is this the first electronic fidget spinner? I... Yeah, this is the first one that uses tactile feedback which I really like. Yeah, right? Yeah. And I mean, somewhere around my room is version one and that the MOSFETs couldn't handle the current of the motors. I just picked the MOSFETs based on rated current and not rated power dissipation. Oh, yeah. Well, you've learned a lot as an engineer. That's a big lesson. So the code is in Circuit Python of course. So can you share my code screen? Oh, yeah, yeah. Yeah, no problem. And one who merges these things in so I think you're talking to the source. Yes. So I've got some things that... So I've got an... Oh, I didn't show the Neopixels right. There are three little reverse-muched Neopixels. Sorry, I'm all out of source today. Cool. Oh, there they go. Ooh. So you have the motors defined here. They're PWOM-able buttons and some button initialization code. The rainbow wheel code I totally copied from the Uber guide. Sorry. No, you should. That's what it's there for. Yeah. We have a copy button. Yeah. There's a copy button, it's true. And then I have the function for spinning it. And the idea is it kind of feels like a click. So it's like a very short pulse of the motor. And it does work. It's very hard to demonstrate because it's a fidget, but it does work. But people can make their own. And there's also the... Yeah. And that's the other cool thing. It's completely open-source hardware. So it has a breathe mode so you can try to breathe to it and it helps guide breathing, main loop. And yeah, that's pretty much it. And it's kind of my ideal fidget. And I'm hopeful that other people like it too. But I mean, I've shared it with a few friends and they all seem to think it would help them. Remix it and build it around. If you remember, drop me a note, ptdatafruit.com. I'll make sure we get it in the newsletter and get the word out on it. All right, thank you. All right, thank you so much. It was great. Thank you. Nice work with your project. Yeah, that was cool. Someone finally made a electronic fidget spinner. All right, so what I think I'm gonna do is what I mentioned before. Melissa, we're gonna bounce to set up for Ask an Engineer. Okay. And how about you take care of the next three folks and we'll just watch to make sure that you're out and then we'll start Ask an Engineer. For the folks that just tuning in, we're doing a slightly different set up each set of kids. So we're like kind of like mushing all the shows into our bedroom and multitasking at the same time. So we just need a couple of minutes to set up. So thank you so much, everybody. Have a good new year, Melissa. And thank you, Melissa, for taking it from me. Thank you. Oh, you're welcome. You're welcome. Have a happy new year. Yay, whoops, wrong button. Hello. Happy new year. What sort of project do you have to show today? Hey, Melissa. Ready. I've got a little BFF five by five. Oh, okay. I've got a little, it's a micro switch. It's a limit switch and a piezo. It's all kind of attached to the back. And it works as a little, I call it the one-armed bandit, it's a mini slot machine. Oh, that's really cool. Oh, and yeah, it even has sound, I love it. Yeah, so I got the sound, light and sound goes so well together. It's the addiction. And so I'm using the Python set property just to check that final line. I'm recording that and then on, there is a winning kind of animation. If I do get, at this point, it's just, if there's two or less colors, so there it is. Oh, nice. Cool. Yeah, so it's all kind of wired up. I'm using the original cutie pie. So it's kind of limited as to memory. There's no extra flash or anything. Yeah, I think the original one, you could put a little memory chip on it to expand the flash. I think so. I took the challenge and I just did this as kind of a double loop, doing all the matrix math, figured out how to do the columns. There's only one single reel, so the color gets basically offset by each one. And that's kind of what the animation is. It's offsetting each of these reels by one. It looks really good, yeah. It's super fun. And one of the other things is I did the, did use the debounce library. So like a one-armed bandit, it's actually the return. So I'm looking for the rise on the limit switch. Just a little thing that makes it a little more casino-like. I don't know if this is something that J.P. wants to put in his little apartment there in the bookshelf, the D-class. Oh, that would be kind of cool, yeah. The last egg is set up, but yeah, that's my project. It's a lot of fun. I was tinkering with the matrix math and the double loop. So, real fun. Yeah, I just want to say thank you. And to eat a fruit, all the folks who documented it, welcome back, Lamora P.T. Thank you. Thank you for stopping by and sharing. Happy New Year. You too. Hi, how are you? Hello, Melissa, how's it going? Good, could you turn? I think your volume's a little bit on the lower side. I can just talk louder, is that? Yeah, I can hear you a little bit better. I don't know, maybe it's coming from a different microphone than you expect. But I have my Space Mouse hot keypad for Fusion 360. It is a ton of, it's six by six keys. Use the Neo key for the top ones up here. Oh! It's wired because I originally had a couple pieces and I just had originally a flat piece on this side. And then once I kind of got the feel of it, I built this part with the hot keys. And I had a broken Space Mouse so I kind of gave it a second life and added hot keys. I'm using a KMK for the firmware on it and a KB2040 microcontroller. That's really good. Looks like something you'd buy at a consumer level. The actual that I was able to Fusion 360 and kind of added a ton of stuff, especially with the Space Mouse and the bottom grip. And it's really handy for when I'm doing my little Fusion 360 models. And because I hate, you know, take my hands off, moving it, bringing it back, moving it, bringing it back. And it works out really good. And the Space Mouse I plumbed into the KB2040. So it just uses one power station instead of running power to both parts. Cool, that's really good. Yeah, thank you for stopping by and sharing that. And happy new year. Hi, hey, you are the last one here, so. Yeah, I finally got in here to do this. So another keyboard project. Oh yeah? This one's a little older. This is the keyboard off of the Osborne One. Oh wow, okay. But the keyboard interface on the Osborne is just raw access to the keyboard matrix underneath. So I've got a Feather 32 and a custom PCB just to map the pins around. Oh, okay. And now I have a Bluetooth keyboard from 1981. Is that running, what is it running for, the software? QMK, is the floor got in there? Oh, that's cool. Yeah, they did all the hard work. I just mapped some pins and it works. Cool, yeah, I know Jeff has been doing a bunch of those kind of keyboards as well. Huge and chunky and there's actually enough room in this case to hide the entire cable and microcontroller if I wanted. Are you using that with your computer? Yeah, I've got it paired to my laptop here. Oh nice. I lent it to a student worker. I think he had it paired to a Mac. Oh, nice. I had it paired to an M1 iMac to play with. And yeah, it's an old noisy keyboard. No worries. Oh wow. Thank you for stopping by and sharing that. And have a happy new year. Happy new year. And I think that is it for show and tell. Stick around for Ask an Engineer that starts in a few minutes. And I'll be with Lady Aida and PT and that starts at eight o'clock Eastern time. And thanks for watching.
