 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 and show up your project You can find a link in the live broadcast chat over at discord and that's at adafruit.it Slash discord first. We're gonna kick things off with our friend Jay from digikey Hello, how are you? I'm good. How are you doing? I'm good. Yeah, what's you what you got there? This is my newest robotic child, which I have named binary It has been the longest project. I think I've done this far. It's fully it's controlled right now with this little remote At least the body is the head at all random movements and blows bubbles as well. Oh my gosh, that's amazing Yeah, it's truly messy But I was able to get the motor controls to work so I can just show it like this right now But it rolls I just guide back from visiting a friend to actually test it out in the field And it does a pretty good job and this is going to be my project. I'm taking to roll maker fair Wow, that's gonna be quite the long journey. And so you showed the remote. Is that using Bluetooth? To control it or what protocol are you using? I am using the Radio control one radio control. Okay. Yeah, so it's funny. It's actually made two of them I have one that's just this Which is like the boring handheld one, but then I got nerdy and I made one. It's a cuff link That can be one of this for like to pretend to be a power ranger for a night. That's great Actually, it's everything's really nice sweet All right, and then for the brains of the robot. What's the board inside there? It is the pie pico. Okay with the catronic robotics board Very cool. I'd like to keep it on top the way I can point out and show it to people. Yeah, that's great And then for the eyes are those screens. What's happening there? Those are just lenses, believe it or not Beautifully tinted lenses with LEDs in them. Yeah, and they have a really great look or like even like at night Or even in the bright sun you can see the eyes very well The only problem I've noticed thus far is what stream it reflects so you get like this happening when it looks at like a screen Well, then you get you're getting their point of view kind of yeah Yeah, I'm probably the record the robots like eyeball one day you like some point of view content. Yeah. Yeah, that's awesome All right, and is this a project that you're going to be documenting or is it just yeah My newest plan now since I've done a lot of robot stuff this year, but I haven't documented anything This is my last build Big build for the year and when I get back from our next event I am going to just sit down and just try documenting everything That's my goal like no no more no more stressing for a little while and I'll just sit around and just document everything Get the code out there for people to use it Get the STL files. That's that's my plan for the rest of the year That's excellent and I find when you document a project or anything like that Like you can really appreciate the project like you can just see all the work and really think about all the steps and everything So that'll be a nice way for you to end the year. I think yeah Yeah, yeah, that's awesome. Well, thanks so much Jay for coming by. Thanks for having me. All right. Have a good one Next we're gonna hear from folks in the ate a fruit community and that we're gonna kick things off with Scott Hey Scott, thanks for having me. Thanks, and thanks for hosting. I thought I'd show GitHub actions today Okay, which you know is always exciting. Yes, but the main thing here is this is I've been working on the micro Python 120 merge so circuit Python is based on micro Python, but we don't always Base ourselves on the newest version And so for circuit Python 9 we're updating from 118 All the way we'll go up to 121 which was just released Okay, and so we've done 119 Dan did one Dan and Jeff did 119 Now Dan and I are working on 120 So I got the yeah of actions working and this will tell us which boards still fit and are actually like compiling. Okay So a lot of green a lot of green. Yeah, but not all green And you can see some are going here as well still so We're making really good progress I did an update today that integrated the idea of 5.1 changes that I was doing previously Okay, so this is really like circuit Python 9 starting to come together. So I'm very excited about that You know Dan did a ton of work already, so I'm excited to be able to help that and More good things to come into this as a little more called it the the stew pot of circuit Python 9 Yes, and thank you so much for working on this. I know it can be tedious, but Really It's what everything's built on. So thank you. Yeah. Yeah, and you know the micro Python team does a great job, too So I'm excited to be based on 121 in particular. So I have motivated. I have reason and motivation to get us all up to date Excellent. Well, thanks so much Scott and looking forward to seeing how this all comes in for circuit Python 9 Thanks Liz and thanks for testing as well. I really appreciate it We're much better tester than I am so I appreciate it. No problem. All right. Have a good night. You too Next we're gonna hear from maker Melissa Hey, Melissa Hi So I have I showed off a couple weeks ago that I've been working on adding Or updating the link a display. I know so it supported the monochrome gray skill Displays and now I have it working with the ink displays as well. Very cool And so I was just gonna show it off updating here Just takes a little bit, but Instead of against written in pure Python. It's actually works pretty good sweet so it's just now displaying just the ruler there and And So I want to add some more displays to there. I have up to you that I want to test and It's actually working pretty good great and just so folks understand how is this different from what was implemented before? Before used a frame buffer that worked off of the Adafruit circuit Python EPD library, which it just You would basically draw with like pixels or lines or circles or whatnot. Whereas this is 100% compatible with the circuit Python display. I am Very cool. I very badly tried to implement the seven color EPD with the previous driver So I'm excited to test it out with this. So thank you for adding this. Oh, thank you Yeah, all right. Looking forward to seeing more of this. Thanks so much, Melissa Thanks. Okay. Have a good night. You too. Next. We're gonna hear from Ann Hey, Ann. How's it going? Good Liz? As some people know I'm kind of a Star Trek fan and when I saw this this picture on the internet of a Star Trek Control panel like for or something. I thought that would be the perfect thing to implement Not in plexiglass with paint on it or something But I've been doing PCB art with my latest projects. Excellent. So I I created this PCB it It has What white silk screen and black? I'm printing and there are places where you can see the metal of the circuit board or see through it the substrate right and I'm talking to the more she said I want to be interactive. So when you push the well if I can Yeah camera if you push the buttons their capacitive touch And they light up the lights the corresponding lights when you touch them so one could Easily take that and say instead of lighting up a light Make a switch contact and you could actually make something that Used a code to get in somewhere or it just looks kind of cool. It kind of looks like a phone or something It uses surface mount resistors and reverse mount leds and a couple of Cap touch Chips that we also have a breakout for in the Adafruit store And and a battery here So I'll be documenting this and the Adafruit learn guide this coming week And other people can see how they can make this or to mix it up and make a project of their own That's awesome. And you had another guide that you did previously that kind of went through how to do all the art and stuff Did you use a similar process for this one or do you find you? Yeah, exactly. They build our first day I don't remember what the because of NASA Well, the NASA one was second that had just passive components on it without chips The first one was a jewelry. Yeah, right. Yes. Um, I made some Floppy disk earrings and a pendant that was just to show it. They all use winter blooms software for converting vectorized art into key cad Footprints So it makes it really easy to go to make a design and import it rather than having to try to implement complex art directly in key cad, which would be almost impossible Yeah, I've done a little PCB art for fun And I was always doing it the way that you have like all these bitmaps that you're like Layering and then if you find that you don't have the right size you have to regenerate them all again And so Yeah, so these guides are really helpful for folks. So thank you for writing those up Oh glad to do it. Um, and um Lady eight. I think once maybe uh another one maybe with a microcontroller on there somewhere So, um Keep keep tuned into the aid of fruit socials and we'll see how it goes Excellent. All right. Well awesome job. Thank you and for coming by Thanks, Liz. Have a good night And now we're going to go to john park to play us out Hey, Liz. How you doing good? How are you? All right? Uh, so I wanted to show the progress on my project I've been working on for a few weeks now and uh, it has now been glove-ified. So Wow, uh, this is my uh feather prop maker Synthesizer with a built-in amplifier and speaker and a color sensor on the fingertip here very cool Uh, and so I just just bolted all this stuff which had been on sort of a like a Lego jig that I was using before Yeah Now is in more wearable format and uh the Palette of uh of Lego colors there that I'm using if you uh, if you want to go to the overhead, that'll be a little easier Sure, I think so I had started with about 60 or 70 lego Bricks in all the colors that the one by two brick uh came in and started to figure out which ones were the sort of ideal 12 That uh were the most distinct from each other in the nine wavelengths that this little color sensor can Can measure uh had some great color comparison code contributed by c grover Uh, who's one of our uh great community contributors. Yes, we help me with a um a method of of Figuring out which which of these were different from each other as well as a tolerance setting so that I don't have to be like Exactly the same lighting conditions and exactly the same spot. Uh, so I've got uh synthio code running on here It's actually also playing another um library from C grover, which is a chime library, which does some um kind of like tubular bells modeling some resonant Modeling of overtones, which is really cool. Yeah, and so now I can uh play i'm playing some little um Sort of arpeggios based on the different colors. So here you'll hear There's a lower note on this first one. This is the top note up here And we can just go among them And so one of the things that really impressed me about the accuracy of this sensor is the fact that I've got Four different basically green Voices here. There's this sort of lime green and then there's this sand green. There's this uh turquoise teal kind of And then this one's bright green and they're all very distinct from each other as far as the sensor goes Same with these. I've got like a a light lavender and this medium purple and if you come And play those you can tell that they're different tones now one interesting thing is if i'm far enough away from this one Sometimes it reads as purple just because the okay the brightness value Yeah, so that was the same note. So it actually registered that lavender. So if I come in it from the side It's a higher starts on that higher pitch and as I was drawing away So actually jan is working on some code to look at there are actually Eight color channels that we're reading. There's an infrared channel We're not using and there's a clear channel which is kind of the white light or brightness Overall lux channel. I think And so jan was looking into some code to use that also as a way of Scaling the values so that when you're further away you can still say, oh, yeah, that's I can be confident That's pink. Um one of the other neat things about this is that There are other objects around like here's a plastic pokeball. That's Basically the same red as as the lego there. So that'll work That'll trigger it there. I also found I had a uh a little object here that's pretty close to the the turquoise Oh, it's actually hitting two you can you can hear it running through of them. So That's why I wanted to get to these these 12 here that were distinct enough from each other. They generally don't have false That is the progress on that. So I've been documenting that as I go and Should be putting a guide out next week so that people can make their own I think there's some Possibility for doing maybe two gloves with two basically complete systems because this is not sending midi. It's not It's it's all self-contained So you could basically, you know, if you're gonna if you're gonna get this glove, you're gonna end up with the other one Anyway, I just went to the hardware store So you might want to do two like that. Um, you could make the the lego bricks wearable You could use this completely differently like a sequencer If you just wanted to sequence brick colors and have it automatically play songs Like you're just running across a a score or something like that I think there's a bunch of possibilities and uh, I'm excited to see if people uh pick that up and run with it So, yeah, that's super cool. Uh, I'm excited to see the guide E.T. phone home with it if you want just in time for Halloween That's my costume. We figured it out. Yeah, you can just like go through the grocery store and like play the different like Oh, yeah. Yeah, it's true Just play all the objects around you. Um, we got to the point where If I tuned the samples the sample time and the sample slices to be much longer So take take longer. It's not as fun for music, but I think I was uh able to distinctly Read accurately almost 30 different brick colors, which is kind of wild And and maybe you could do it with Um with more care you might be able to do do all of them. I don't know, but This is all I need Little uh chromatic scale if we want to yeah, and will you be talking about this on your show tomorrow? Yeah, I'm gonna I'm gonna bring some of this I'm gonna show some of the code behind it and uh Also make some do some tuning and adjustment tonight and uh might be showing some other stuff too. It remains to be seen so All right, so, uh It'll be a surprise to all of us what I actually do tomorrow. So come on by and find out All right, looking forward to it. Well, thanks so much. Sean looking forward to the guide right on. Thanks, Liz Have a good one All right, and that looks like it's gonna wrap up show and tell for tonight in about 13 minutes So ask an engineer is going to be live with Lady Aida and Mr. 80 later 80 Mr. Lady Aida, um, so tune in here to see that and have a good night. Bye folks
