 Lady Ada, what is this? This is show and tell right this is lady Ada This is mr. Lady Ada. This is Ada fruit behind us and dramatic Broadway's open everybody that's right bring it here Welcome to welcome to Ada cabaret. We've got about 20 minutes of a high of scootin Yeah, this is me scooting. We got about like 20 minutes of us and people from the community What are they making hacking coding? Robotting 3d printing and more we're going to find out. Let's start off with her stuff is J Represent did you key and more on this week this week? I'm working on Vaughn He's been a robot working up for a while now I've made a few new upgrades recently, which is a opening head So I cannot look in here and get all the parking stuff I want some where the circuits are hold it hold it like the word held Currently is using a interfruit trinket pro So I'm gonna turn on it quickly and it does basic random movement kind of slow not too fast as of yet So don't anything to break. Yeah And recently I finally got the wheels to move a bit. So we're gonna test it here and if it explodes on camera I am sorry. Yeah, well, it's because it looks like the robots waking up. It's cute That's like me in the morning before I have my coffee. That's what I look like It's a little bit too fast sometimes Before it was too slow now, it's too fast. It has moments This is a great looking robot. I love the personality that your robot has. Thank you. I browse. Yeah, I browser are cute It's based off of my old MacPie eyes from last year All right, what else you got going on? Yeah, what are they're like some a contest or anything going on? They're contest starting this year, which is amazing and also this year. I'm your judge or a judge I'm one of the judges on this thing. So I will be looking at all the entries. So please enter chance to win big Okay. All right on Ask an engineer tonight. We're gonna show there's like a two-minute trailer that has all the information and folks can go to hackaday.com and check out the Contest the really big prizes as usual this year It's brought to you by digikey and supply frame and then one little side note I just wanted to mention this so we had we had a new employee who just started Adafruit and Their job application was you know the normal job application for one of the roles here But they made a robot and they brought in a robot. It was one of the inner very cool. I think that's the new modern thing So Jay, I'll so I'll send you a link to their robot project later I think it's hard. It's hard not to stand on top of the the pile when you bring your own robot Yeah, interview and So all those job seekers out there my suggestion is bring a robot with a robot Trust me. It definitely helps Even if the interview doesn't work out at least you had a really good time with your robot you got a robot You had one friend there that was backing you up. That's right. All right, Jay Well, good to see you and Good luck on all the entries and more should be a big year for the hackaday price Is Jephler Yeah, my professional reference is also a robot so he's gonna program to say all the good things about me and So If you brought this robot and you set it down the robot was like hello My name is robot and I will tell you about Jeff Jeff is a hard worker I that'd be like well, I'm actually like I believe anything robot. Yeah, I think you know and news from the future Category at least to have that on on when I was at make You know one day it'll probably be AI that does your references will look at the summary of all your work And I'll regurgitate like a it'll just spit out a reference Yeah, yeah, coming soon. Okay. What do you got go on sweet Jeff? Yeah, so I 3d printed my own floppy drive enclosure because I've been doing these floppy drives a lot, but you know, there's guts and stuff inside here So I know I know no and Pedro did one but I wanted something that was like more evocative of it's the 80s and you have a floppy drive and So the two halves screw together the floppy drive screws in the base and the back is just open so I can swap out my Different floppy interface boards and yeah, it's like the most complex thing. I've done in free cat to date Another page of their existing floppy because we already have like a 3d printing floppy guy So I don't think you'd be like hey, here's here's Jeff's take. Oh sure I could do that Yeah, I know that the map pretty much everybody who has a floppy drive is watching the show right now Yeah, so you have all the market I looked around on eBay. I'm like this style of case costs a bundle So it's it's crazy. You'd think there'd be like thousands of those external CD ROM Drive Just put a five inch five and a quarter inch disk in there's not or I was using the wrong search terms or something Anyway, threaded inserts got to go with the thread All right, that's what I got and PT will probably be showing a floppy demo of the new stuff Technical in our very special retro section. We have lots of photography videos and more so tune in tonight Right after time travel because we travel back in time and then we do it and then we're back in time And then we're like let's talk about floppy drive. All right Now in Pedro Hey, folks. Yes. Yeah, so this week. We got a super simple artisticky Topography based sure sort of Yeah, yeah, so a lot of the book covers that usually see are like made out of paper and PT was like Hey, big like a 3d printed one and like thin it out to you know Yeah so when people come over or you have your background for like a you know video chat you can you know your bookshelf can Look even better. Yeah, so it was inspired by one of those a topography Instagram accounts that had like a couple of really cool ones and Yeah, this was a really good one to do like have it line up with the actual artwork and then Yeah, the one that I saw and I sent it over to know Pedro was very artistic and like proper and everything and I'm like ooh comic books graphic novels and so I think we took a different take on it but I think you people would be able to Use your files and remix and make their own. There's a lot of graphic novels that look kind of like this I think it's a standardized size and the Cool thing for me that with the 3d printing is I was just impressed that I was able to print the letters straight up You know with the supports in there and all That looks real like if I saw that in the store and that was part of the graphic novel I would just assume it was part of it. Yeah, one thing I didn't mention though Oh, is that is that it does take quite a while. I think it's like 28 hours just to print this guy But you can read the book and then when you're done with the book But definitely worth it and of course if you have a book that you're spending that much time on it's definitely gonna protect it It's pretty thick. So yeah, yeah, the audio book version is just 28 hours of the sound of a 3d printer. Oh All right, we'll be showing these videos and more tonight on Ask Engine or you got anything else before we Yeah, yeah, I think we got a little sneak peek of Here's the cube cube. So it's gonna have six sides. This is a 2.5 millimeter pitch 64 64 RGB matrix. So there's six of them. Yeah, and here's the insides We're just figuring out the mapping with the the data cables and using some some power rails to get all the power sorted We've been using magnets for everything. So we've got a lot of magnet tabs. That's cool. So the pie can come out like this Yeah, the rest of it has these magnets Little labels on it. So this is top. So I know this is the top We also have little arrows the signifier where the data flow should go So yeah, put it on there properly. But yeah, something in the next two or three weeks Yeah, and I don't want to spoil it But you know if folks are wondering what this is this is the Lego mini fig set for the movie cube So if you want to torture the little mini figs and have them try to figure out how to get out In this giant corporate trap. That's what it is No, or it's a board. Yeah. All right. I'm going to Excellent movie the cube by the way, okay. Thanks so much All right, next up Liz and Liz is So I've got a kitty pie ESP 32 s2 and it's connected to pure data So my screen is with a socket and so just as like a kind of proof of concept I've got two neo sliders and when I bring them up The grid also You can like read data from a socket and like there's no text I mean, it's all just these blocks that are connected and it's like yeah, you can parse it out and it gives you the end Yeah, what's so it what you basically do is you label the data with a piece of a string and then Pure data has this cool thing called right and you just put that what that string is and it pulls out what the the float is And it's really easy to get up and running, which is really cool That's cool. I'm just neat little like looks like a pen drawn visualizer. Yeah. Yeah, because normally You can kind of draw it with a mouse. So yeah, but as they look at the the sliders to plot it. That's cool Yeah, I think it's neat to combine, you know circuit python python with pure data Um, I thought it'd be a neat example because it's like, you know, we don't want to rewrite drivers over and over again And I don't even know if the pure data does I've scored C. So how would you do that? A lot of people use Arduino, but I think this is kind of an interesting idea that you're like, no, let's just use wi-fi I'm like, okay. That's one way to do it. Yeah, because it's just um, connecting to your computer's ip And you're telling pure data listen on this fake port and then you're connected Yeah, all right. I will let you well. Thanks so much. Listen tonight on ask an engineer. We're gonna show um, your video of the pysyn that you did and then um, or the visualizer and then also, um, if you haven't already everyone check out aideford's tiktok Liz just did a one minute video in tiktok style. Um, turn it really good. So check that out Liz talk All right. Thanks, Liz Fomy guy How's it going tim? I was it been just by the way everyone check out tim's show on Friday's at 2 p.m. Eastern It's really good. Yep. Yep, uh, and perfect uh segue for this as well I was working on some of this stuff on deep dive last week So if folks want to see the code um that went into some of these examples You can check that out for the video and I'll be on again this friday playing with some other stuff as well. So um, what I have today is more of Just a small example project than a fully fledged out, uh, project But I basically have been working on some helpers that go around the vector i o module that's built into circuit python Um to try to make it easier to do some stuff with it. It's it's very flexible It can kind of just make arbitrarily shaped polygons given a list of points Um, but when you want to kind of rotate those polygons around you sort of have to just figure out all of the points That represent the rotated ones So what I've done is I have this little helper library and one of the classes that's inside of it is a rotated polygon So that you can define your polygon points once and then just tell them the rotation you want it to go on And it will figure out the rest of the math for you. You don't have to care what the rest of the points are You just define it once and tell it the rotation. That's nice. So these are a couple examples that show how to do that and The bottom one that's static. This one is actually in the repo I'll drop the link for it in the chat when I am off of here But this one you basically just define a couple of things like the the points in the polygon Oh, I've gone away from it Up here a little bit you define the points in the polygon You define a size for the circle radius and then you define the count for how many items you want it to draw So you kind of can quickly change those variables and it will adjust what it draws It will change how many there are Which will draw more and make more colors And then on this one on the top here, I even took it another step farther and actually did some of the rotation stuff dynamically It is it's a little choppy and I do also have a time sleep in it So it is like moving a little bit and then waiting and then moving a little bit But it kind of makes this interesting sort of kaleidoscope effect Where you can code some really neat shapes in here and then you can run the rainbow io stuff and have it change colors So i'm thinking about maybe trying to make like a 3d printed kaleidoscope type thing And we put the screen in the end of it and maybe it shows Some of these fancy designs, so yeah, you can get mirrored acrylic and just have it You know an angle and then when you look at it it could have like a really neat repeating pattern Yeah acrylic would be really nice, too You're redoing like quick draw, but in like python All right. Well, thank you so much Tim and then again folks can tune in on friday's at 2 p.m On all of our social media channels Tim has a really good deep dive. That's what's called Where you can step through a lot of this stuff real time It's a literal deep dive and we also have new graphics and as a cool sub Submarine, okay. Tim gets a submarine. All right. Thanks. Thanks, Tim. All right mark. How is it going? It's going great today. Um, so I just need one second to Start something up because there's fire involved today. Good and I didn't want to Start this beforehand okay This also makes sure my Camera is working Okay, so a couple years ago one of the first random projects I did Was as covet was starting and my birthday was right after that Uh making robot to put out my candle. So I didn't have to blow on it So with two years of experience in circuit python now, I've decided to upgrade the robot and We will see how a live demo works Now the other thing I've learned in two years is to never trust my first uh plan And add an emergency button Okay, okay And now I've taken parts from the various eta boxes and decided if you're gonna Have a backup you have to make sure the back. I think you I feel like you learned a lot You could do it. You could do it. This is why I'm not too worried about robots taking our jobs. Yeah Oh Was it gonna make it? Come on Like the story of your apartment, but uh, you know, yeah, yeah, I've got towels around because Yeah So this is what two years of Playing with robots in circuit python and Learning does you can get a very wet cupcake? This was all made in unity real time and this is the intro of the next Pixar movie. No Yeah, I do like how the The movement worked on the yeah, there's a nice little like jumpy, uh Almost a live look to it. It's like Yeah It's trying to put out the candle, but it's just gonna do it. All right. Well, um, most of all, I'm glad you were able to do some more Birthdays. We're all here together mark. Good to see you Yeah, maybe more. I can't wait to see how you put out a candle next year We'll see what else I can add to it. All right. Nicely done. All right. Thank you mark All right, everybody that is our show until this week. Thank you everybody for making this the best half an hour Of our week every single week showing sharing your projects together. It's the longest running show until on planet earth that we know of Maybe even known universe. We'll see Um Inside this bubble could be We'll see everybody next week 7 30 p.m. Eastern time on wednesday. Ask an engineer starts in 10 minutes One or a couple minutes 10 minutes or so. Okay. Okay. Bye everybody. See you next week
