 Welcome back to another 3D Hangouts. My name is Noel Ruiz. I'm a designer here at Adafruit. Good morning, everybody. I'm Pedro Esco for AdafTech here at Adafruit. And every week we're here to share 3D printed projects featuring electronics from Adafruit. That's right. It's sure we can buy in 3D printing and do all the electronics to make inspirational projects. Hello, everybody hanging out in the live broadcast chat room. If you'd like to join us during the show, you can do so by hitting up the Discord server. The link to that is discord.gg slash Adafruit. And we are hanging out in the live broadcast chat room. We'll take a moment to welcome everybody to the show. Thank you so much for joining us. We've got some fun things to share, some retro tech and some inspirational retro stuff. Good morning. Good morning. New things. Give a shout out to everybody hanging out all over the world. We got rolls. Good afternoon from snowy Norway. Good morning. We got Jim Hendrickson. We got Dew Wester. We got Andy Callaway, Susan, Paul Cutler, Yanni, all hanging out in the Discord on YouTube, on Facebook, Twitch, where else? Twitter? Yeah. Please forget that. All the social channels, the new ones that aren't there yet. Like we're even on, remember, podcast iTunes? Oh, yeah. Swiss still call it iTunes. Yeah, we have a podcast thing there, too. Very well. Good morning, John, from New Jersey. Still doing shout outs. All right, let's continue on with the show. Cool. Let's chat about some stuff and do some housekeeping. So let's kick it off with some freebies. This one. If you go to 85.com slash free, you can see all the different things that are available right now while supplies last. The more money you spend, the more free things you're gonna get. For orders that are $99 or more, you get a free half size from a Proto. That's pretty cool. And then for orders that are $149 or more, you get the half size from a Proto plus a Stem-a-Qt Breakout Board. If you have an account with Adafruit, we'll make sure you don't get the same one twice. Otherwise, it'll be randomly selected. And for orders that are $200 or more, you get the Stem-a-Qt Breakout, the half size from a Proto PCB, and free ground shipping for continental U.S. only. While supplies last, these get added automatically to your cart so you don't have to do anything special. They just get added, which is nice. Cool. Okay. We have a newsletter that happens once a week called the new newsletter that's focused on the new products that are added on the weekly to the Adafruit store. You can go to adafruit.com slash newsletter to subscribe to that. And for daily content, you can go to adafruitdaily.com and subscribe to the many categories, such as Python on microcontrollers newsletter. Shout out to everybody who's been submitting their stories and subscribing. Really great place to get some fun projects and inspiration for all things Python on microcontrollers. Check out the jobs board at jobs.adafruit.com. And check out all the new listings that aren't there. And we'll circle back over to the Discord. So if you'd like to join us during the show, you can join the Discord. Another link is adafruit.adafruit.it slash discord. That's a little secret one there. And that's the housekeeping. All right, let's go ahead and jump into this week's project. All right, let's head over to the overhand. A little bit of a trip down memory lane. What a floppy work has been going on over at the desk of Lady Aida. She's working on some cool boards. To be able to interface with some of these. The main thing that kicked this off was, was it, it was the Prince floppy disk that needed to be rescued. And PT was the only one that had a hard drive that was able to even read it. And this sparked Lamar's interest in being able to get these to work with modern hardware. So she had a bunch of drives on the desk and wanted to make sure they were all protected. So of course, I had to three print some nice protective casings for not only the five and a quarter but the three and a half inch drives as well. They were able to get some cool translucent cases on some sellers on the internet. So we wanted to try to maintain that look with having the translucency. And that was really my main challenge in trying to get the available translucent colors to be as translucent as possible without being, not being too thin and still being able to protect the cases while they're on the desk. One of the other challenges that Lamar gave me was to have them be stackable. So they are able to stack a three and a half inch drive on top of the five and a quarter while still maintaining all of its strength and translucency. So take a look at how translucent we're able to get these. These are about a millimeter thick while still offering all of the rigidity that you would need for the drive. So just a little close-up on that. You can see that I even have these, the eat-of-fruit embosses. What I was trying to do here was two things. Test out the geometric patterns inside of Fusion 360 and have them be a little bit more transparent. You can kind of see there that it actually, the emboss makes that thinness so you can see through a little bit better because of the height requirements on the five and a quarter. It's a little bit less translucent to give ample space for the motors to rotate without it interfering with anything else and a little bit less so on the top here. But these cases just slip in and off so there's no hardware required to screw these into anything. Let me just go right over like that. And slide in like that. It's pretty easy and you have the back open on the, the back is open so you have access to plugging in all of your power and your, I was gonna say, scuzzy adapter but whatever interface you're gonna be using to hook these up to hopefully some circuit Python boards and the works. So super cool way to sort of bring the old retro tech back into the modern age. A lot of people on the video were asking, oh, why are you guys working on such old tech? And of course, very happy to see some of you commenting on there that a lot of these are still in use in like industrial purposes like in the government and military stuff like that. They are still using these. And for data recovery, I don't think you're gonna find like old Bitcoin wallets in here but there's definitely like, I don't know, wills or like photos and things that might be stored on some of your parents or grandparents old data. If you ever go through an estate cell or something like that, you can see or find some old documents on disks that are no longer readable. Hopefully you can pick these up like on eBay for like 20 bucks or whatever. So a nice little way to sort of with archive, archiving web stuff as time goes on, you definitely want to have some sort of ability to read all that old stuff again. So we jump into the learn guide for this and get all of the files, the Fusion 360 files, the step files since there seems to be some chatter on or to upload files and all that. I'm gonna make sure that everything is in one place. So super simple just goes over what I just said, you know, the reasons behind it, why you might want to have a nice little protective case for your desktop, save some space and all that. And one of the things I wanted to show was like how I created the geometric pattern but it is a paid add-on to Fusion and my trial already expired. So we won't be going over that. Let's go ahead and jump into the 3D printing. It's gonna be a pretty short one since it's pretty much just the case. And you can see here in, if you scroll down, there's all the files and links to all that. And the setting that I found made it the most translucent on this was enabling the fill gaps between walls. I'm sure it's like in the Prusa. We're using the Chura slicer here. So that's what it's labeled as. And we're gonna fill the gap between walls to everywhere. And that's just gonna ensure that you have one, so there's three perimeters, two on each side and one in the middle. And you need to have that one in the middle to sort of bind the other two together. I did try just having two perimeters but that falls apart especially with such a big print. You can't get some warping as the height increases with the print. And then the other thing, one of the other most important settings that I found, for getting the most translucent, clearest case was comb mode to off. Otherwise, the nozzle will sort of try to wipe itself on the inside and as it's doing that, it's creating sort of like a frosted look like in between the two layers. And you do not want that if you're trying to get the most translucent case that you can. So combing has to be turned off in the fill gaps, set it to everywhere. And that's just because of how thin, quote unquote thin, being a millimeter. How thin is it in CAD? It's one millimeter. Okay. And then how thick or thin rather is your line extrusion width? It's all like. 0.4. Yeah, 0.4. It's all standard. 0.4. Nothing there changed. The main things which I have highlighted here in the orange box here. I don't think folks are gonna play with their extrusion width too much, but we have to with like the ultimate makers would tend to go to like 3.8 or 3.5 or 3.3. Stick with 0.4. It's not labeled there, but you can just. The standard setting should be able to work, even like the 0.48. And if you're using a different nozzle, that's not a 0.4 nozzle. You're gonna have different settings. Looking over at the discord here, Yanni posting it. We were just watching this from her. We were just literally watching. I remember watching that so early. We were literally watching it. I was working at the App Store at that time. The App Store. At the Apple Store. And the retail Apple Store back in the early 2000s. R52 for anybody who worked at the Apple Store. You know what store that was? R52. Is that the code name? Yeah, they did the stores by like numbers. That was the one in Wellington. And down in West Palm Beach, Florida. And I lost my train of thought. What was I talking about? We're talking about floppies, old men. I know, we were joking. When these came in, I posted the video. When these came in, I was like, hey Gavin, look, because he refers to everything from the 90s. Old as, oh, that's so 1990s looking at the, you know, the way the mechanics on the drive works and everything. Older than 1990. Yeah, so. Did we finish the three trending days? I think that was it. Pretty much. We talked about, oops. We talked about the, the extrusion width is what I was saying there, but. Heater bed, prints completely up and no support materials. I have drafts on the little, the walls, so that should print up. There is a lip on one side. Let me go back to the right. Jump right here. There's like a one millimeter lip right here just so it doesn't go past the, what is it, the front cover on this. Same thing with the three and a half inch. There is a lip on here. So it doesn't go all the way through and all these little, the front cover stops it from going all the way through. I think the other thing that we can look at is just translucency of the colors because I did try printing a bunch of them and these, the blue, orange and green were the most translucent. I tried yellow, red and those were not as translucent which is kind of weird because you figure yellow, you know, would have, would be a little bit more translucent as the, it was like the green and the green was more translucent. So. Green. Here it is. So yeah, you just have fun printing all the different colors and recreating that Macintosh scene. I should have took pictures of these. But these, one thing I didn't mention in the 3D printing section is, or the settings is just how long these take to print. It's about, I think it's like eight hours for the little one and the big guy is 16 hours. So you're definitely gonna have to bring your patience with that. And we can actually test out how translucent they are. So this is ice blue from Filamentum and I think that's like, pretty much the only brand one that I could tell you what it is because all the other ones, they don't, they don't sell them anymore especially the orange which I'm so bummed out about because of how translucent, you know. It turns out, looks better on the back. And then, yeah, so here's the green. You can see how translucent that is. This doesn't really capture the popping of the color. Oh yeah, yeah. Or color temperature in this webcam is a hill, not true to, true to life. There you go. It's a little bit better, a little bit more yellow. Here's the yellow. And then the least translucent of all is this red. That's pretty good. Yeah. You can't see the- When the light hits it just right. Yeah, I did have to play a lot with how I lit this to not show because it looks like it's, the layer lines are extreme. You have it at certain light angles. Yeah. It's like, whoa, you got a lot of ringing. Yeah. So inside the file you can obviously delete the Adafruit logo if you want. You won't be able to change it around or update the settings unless you have the paid or if you're on the trial version of the geometric pattern. It was in what the heck? We're already paying. I don't know. I mean, you can do all this in inkscape, illustrator, just create your artwork and bring it in. I don't see why you need to place your time on it. No, it's exactly what, the point. It's cool to play around with settings. Exactly. And it makes it fun and experimental, but. Yeah, what I'm gonna have to use now inside of Illustrator, you do have the ability to play with a lot of the settings. It took a lot of the ease away. I mean, it took, it gave you a ton of ease. Yeah, it was just a slider. And you can experiment with different orientations. So this is a circular based pattern and this one spreads it out and gives it variable sizes. So it's kind of neat, but. Yeah, that is, again, just a slider. There's no other tool that will do that so quick and easy for you so I can see why you thought it was really cool idea to play around with it, but. Yeah. Those three things, we were testing it out and the other thing too was the emboss. It's inspiring you to create your own kind of like patterns for your cases. They don't have to be just a flat simple thing. You can really stylize it. Exactly. It's some sort of artwork. It's vector based artwork that you can bring into your CAD. Yeah, and showing the least translucent of all is the. Purple. It doesn't look too bad. Yeah, the Blink of Purple. Oh gosh. So we're gonna have Blink of Purple. Goes really good with the yellow. Good way to do your color matching. But yeah, here is what it looks like with that. And I think these are from Ultimachine. Who has, who's been with me for a while? Yeah. That's as translucent as you can get with the darkest color. And that's pretty much it. You got your vents to dissipate any heat. Yeah. You could have powered these, but they wouldn't power. Yeah, this guy would not. So it shouldn't have any interference. You can kind of see. We sent two to LaMange. Yeah, to verify it. Go ahead, push it live. So as soon they fit and they were fine. It's about a millimeter of clearance from all sides. So you should be able to operate this without any interference. Cool. Yeah, I'd love to see somebody with an actual working floppy drive. Let's try out these cases. Lamar's busy. Yep, maybe tonight she'll try it out. I don't know. We'll ask during the meeting. Cool. Any comments for anything? Go ahead and drop them down in the discord. The irony is not lost on that. Jim Hendrickson saying that everything, the iMac or how the iMac was criticized for not having the floppy on there. How funny. Remember that? It was, yeah. I remember having to get the. The first Mac without a floppy. Like, what are you doing? It's like kind of, you know, how do you have an iPhone without a headphone jack? Even funnier still was in the video, if you guys have noticed, that I have the three and a half inch upside down. Yeah, it's upside down. We don't know what's upside. We were Mac users. So we saw the floppy disk go in. I didn't know which direction. Orientation, the. The eject is always at the bottom. The eject. Yeah. Or no. Well, you didn't have an eject button. It was all software eject. Oh, you're right. We had a hole. Our first Mac was to perform a 6300. And did have a three and a half floppy. But again, there was no like, I don't remember the button to eject. It was literally just a hole for the. My first. Paperclip. All right. My first electric piano from Yamaha was a PSR630. And that one had a floppy drive. And you would put MIDI files on the floppy disk. So that's how I learned about the floppies back in the 90s. That would have been a good idea. Lamar did mention to, if it did not come with a front, to design the front camera. Yeah, that's what Jan is saying. That the front color cover matching would be good. How do you remove the front panel? I don't know. Are there screws? Is it clip on? Oh, it looks like a clip. But I don't want to break it. You don't want to break it, huh? Even though it doesn't work. Well, this one I didn't test out. In terms of like, okay. Yeah, it's the big guy. Well, we're going to save these for when actual certified phone hardware from the mark comes out. Then we'll be able to actually. Get the mounts on there. Just getting all the pieces ready to do some fun things. Flippy drive. Flippy floppy. Let me know where YT is asking if these are ready. Plans to sell the floppy drives and disk. I don't think the actual drives or disks just. I've heard Lamar say they're easy to come by in eBay and you were able to purchase them on eBay, right? Yeah. They shipped Lake in a day. They're definitely not. There's no shortage of them. Yeah. It probably would have been faster and cheaper if it went to like a Goodwill or a thrift store, a consignment store to see what they have in stock. Oh, maybe. But this was the fastest for us. I'm totally impressed. Look how transparent that is, Pedro. I know. All of these. You can put your hands through it. You can see. Can I put the... You don't have another one? No. Another big one? I can kind of see the translucency on all of these. But again, this only works when the object is smushed right up against it. A pass like a millimeter, it starts getting, you know, not as translucent. And then funny enough, the ice blue, this other one is not as translucent because of how far away the drive motors are on the five and a quarter. So. So how big of a 3D printer do I need? Oh. Big one. Yeah. Very big. You should be able to get three. I'm so sorry. The sizes on them, let's see. It's a given, but like, come on. How big? 300 by 300 by 300. Something like that. Yeah. I'd open Cura, but my computer would crash. Let's see, you need at least 152 by 40. So. 152 tall? 152 length and then tall. Yeah, tall. You need 195. Hey, that's not bad. You think that might fit on a Prusa i3, i4, i5, whatever it is. Yeah, yeah. All right, cool. And that is this week's project. A bunch of cool, translucent pieces for the floppy disk drives. Cool. All right. Cool. Let's go ahead and jump into this week's prototyping. Real quick, just don't forget, go to the learn guide and you get the files there. Get the step files. Yeah, so you can modify it in whatever cat package you'd like to use. That's still there as well. And then you have the fusion files if you want to do any editing. The tolerances. I'd noticed that there was a tolerance difference between the CR3 and the... How about the CP2? Just a little bit where you can definitely see some sort of, where it's too loose on the CR3s. Maybe start printing like just an inch or 10 millimeters. That is what I had to do. Right. And then see if that fits through your thing first. Don't print the whole damn thing. Yeah. Print a little bit of it first. Very good tip, because that's what I was going for the longest time, especially with this guy. He's printing a little bit of it. 16 hours, so. Yeah, let it print for like half an hour. You'll get like that much. Because you don't want it to be so small to where it like bends into form as well you're trying to put it on. And then you can't gauge, you know, what the actual full size of the case is going to be. So let it print for like maybe half an hour. So I'm going to be like, I don't know about that much. If folks are wondering, Vaze mode, did you use Vaze mode? No, no Vaze mode, no. Because you wouldn't have that center, the layer right in the center that's like gluing the two outer. I think the dimensions, the internal dimensions are far more important than the external ones, aren't they? Because it's the internal that's going to fit your hardware. Exactly. Things to consider. Cool. Anybody have any other questions or is there would like to have the front covers changed out? Nippy John. Formal Hunt is asking, yeah, the infill, I mean, I have it listed as 10% but it's literally just going to fill one. There's no percent. It's like whatever one line is. So it's not zigzagging to create the infill. It's just one solid in the center. Which is kind of like a Vaze mode. But in order for Vaze mode to work, you kind of have to have a solid thing, not something that has an opening like this. See you afternoon, good afternoon from Rainey Scotland. Sonosis is asking, do we just need a MacBook with a floppy drive? I'm just like, shout out to Team LLR in France. Shout out. Shout out to you. I'm just looking at the cool speculative highlights. I know, I need to print the sense we're supposed to be talking about prototyping. Yeah, I was still. I want to print this out in this because look at the difference between the pigments on this. This is like the translucent blue and this is like the ice blue. So you can see that it has a little bit more of a vibrant pigment in there. But what this is supposed to be is PT found some really cool Etsy listings that were showing this glow-in-the-dark powder inside of like a CNC machined little encasing that the artist is saying would be really cool to add to like zipper pulls or like wearables. Like they gave other examples which I cannot recall, like a, I don't know, band. Like anything like that would be good for at dark and having visibility if you're like, exercising that night. So we have some of that glow-in-the-dark pigment in there and it looks super cool when it's like glowing especially since the filament that I'm using here is UV reactive. We should have tested how that looks like on the ice blue. But yeah, nice little threaded. Yeah, it's threaded design here. So you can insert your little vial and I'll post links to where to get the little vials and it was a hobby lobby where I got like a nice little assortment of those. And then I think Lamar is gonna try to stock the glow-in-the-dark pigment. I will print these out in the glow-in-the-dark filament to see if that increases the glow or how that looks like. But yeah, nice simple little wearable attachment with glow-in-the-dark capabilities. So we're cool. Nice, cool problem. Yeah, yeah. So this was actually the first thing I was testing that effusion geometric pattern and it did not work on cylindrical objects. It just used a circular pattern. I will show how to do that. Cause it's definitely the, we're gonna have to do it so I'm manually, I'm not paying. Oh no, no, careful, careful girl. Oh, that'll open the powder. Oh yeah, it'll pop out the powder. I need one of these guys. Yeah, that's actually why I have the holes down there. Pop that out like that. And I lost my train of thought on what I was going to say but just what the powder looks like. Oh yeah, I should have brought the UV light. Yeah, it's fine. It's a little tight. Yeah, so this powder is what we're gonna stock? Yeah. It's like the industrial glow-in-the-dark stuff that they mix with like pigments and like artwork. Would you get the powder? All that? Amazon or something? Amazon, yeah. Not the art store. No, no, I didn't look for it there. The main thing I was looking for there was just those. Cause I remember seeing them passing by in one of the aisles. Not glass, just like... No, this is glass. I mean, it feels like glass, you know? I did not think so. I don't either do I. Until I started pushing on it from the bottom, I was like, oh good, it's not deforming or breaking. But yeah, that's what this guy is. It's very frightening. Oh, I know. Cause when I was placing it in there, like you can see, you know, when you have the UV light over here and you're like, oh no, it's everywhere now. But yeah, I'll have two, three, you print like a little funnel. It's still easily, cause I had to do it like a piece of paper. So I don't be, I don't think next week, the week after it. And I think, do you have one prototype to look at? Yeah, let's talk about. So we got some retro game toy inspired project. This is a Etch-a-Sketch inspired project. So we have these two potentiometers. This is the display. It's a 2.4 inch TFT feather wing. We have these two potentiometers. We're using display IO in circuit Python to move this little cursor. And so you have two controls here. We have a button and a toggle switch. So you notice that the screen has this little yellow thing. When I turn the knobs, you can see me moving the little thing. So what's really cool about this, so Carter Nielsen came with the code for this one. It's also in circuit Python using display IO. And unlike your kind of traditional Etch-a-Sketch, you have the ability to flip a switch. Now you are drawing. So you have pen up and pen down. And it's very hard to draw things I found because I've never really used an Etch-a-Sketch before. So it's been really fun to do this. And this is a color TFT, right? It's a 2.4 inch TFT feather wing. It's 320 by 240, I believe. This is a fixal resolution. But you can see here, you can do all sorts of fun stuff. And then I can go pen up, and I can move my cursor around and start a new drawing, I think, if I wanted to. Super. And then you're wondering, what was this button for? Instead of shake to erase, we have a button. So the button erases. And I've been trying to learn how to draw with this tag and I'm very awful at it. About all the, I found all I can do is probably make a face. I think I can do like a little BMO style face. But huge shout out to Cardo Nielsen. Backstory, Cardo Nielsen works on the Eaterford remote team. He does support as well. And he has a couple of learn guides on the Eaterford Learn system. So about two years ago, pre-pandemic, I found one of his guides and it showed how to use an OLED display to create this project. So if you look in the description of our YouTube video, there's a link to Carter's learn guide. You can build this right now. However, it was built before display IO. It was built before our learn guides were on GitHub. So it's, he's completely revamped the code so that it is written in display IO and we'll be releasing this next week. But that is the prototype. That's just sketch inspired handheld. Take a look at the, this stuff is a 3D printed snap fit case. How do I open this? I don't remember. I did this project, I don't know. It feels like a month ago now. There it goes. So you got your snap fit delies. A little reset button pusher on the back case. But yeah, you got your feather in four. We really like the feather TFT feather wing because you just stick your feather in there and you have all these little extra pin outs. So you can see here I'm using these right angled the header pins to make the wiring connections a bit of a plug and play going on. I got this nice beefy battery and a 3D printed bracket here, the green things, what keeps the display mounted nicely to the case. You got your regular pots here. These are 10K pots. Linear, tends to work out better than the analog for this type of thing. Standard toggle switch and these are, we carry 16 millimeter panel mounted momentary push buttons. That's what this is, but it's something I got somewhere else and it has these built in screw block terminals which I'm really happy about because the buttons that we carry in the shop don't have that, so this makes it modular. And when you're filming and you want your thing to be whatever, it's nice to be able to just unscrew those because when you're panel mounting things, you can get, you know, it kind of sucks to have to keep desoldering, but yeah. Pretty simple case inspired of course by like a Nintendo Game Boy, Game Girl, everything snap fits. I really like doing these, when I have a feather based project or any type project I like doing these reset buttons, it's really easy to press it and then when you, it won't press it when you're down on a thing. So it's really nice when you're flat and you're not accidentally hitting reset. Carter did some fun things in the code where you'll be able to easily customize this if you want a bigger cursor, you can change the scale factor, you can of course change the colors and whatever else you want to try to do. What do you guys think about Edge Disketch? Have you ever played with Edge Disketch? It's really cool to be able to do this in the display IO. I don't think that's something that you could ever do with the Edge Disketch, right? Move. You can't do pen up or down. Yeah, you have to like trace the existing line to keep it within sort of like comb mode on a printer. You can see that if you go too fast, it tends to skip a little bit. So you can either play with the delay or just go slow. We thought about some things like shaking to erase, but as you saw, my battery's shaking in there. Yeah, Circuit Python. Love it, on and off switches right there. I have these, these are guitar knobs. They're super chunky, super heavy, and I love them. That is really nice. Hello. These are really cool. I like these. They have the spline in there, built in there for potentiometers. So yeah, these are for guitars. So that's why they're huge. I figure it gets some really, really nice ones because this is the majority of how you're using it, right, with these giant things. We don't stock these, but we hope we do. It's about gate-big. It's pretty thick. It's like two iPods. I was gonna save the whole morning, that's what we're watching. Give me the... It smells like this shit. It was about the same thickness. Oh, it is so close. Pretty close. Whenever you're doing it, and this is with the short headers too, the feather. How's the short headers? Oh, that's fun. All right, that's the prototype. Hope you like. We'll do it next week. Super cool. Definitely have to do something. You wanna draw something? On there. Turn it on. At the bottom. Oops. Oh, that's the erase button. Yeah, that's the erase button. Clear button. Let's see if I can draw a blinker. No, wrong. It's inverted. Ah, I can't do it. You think it's inverted? No. So yeah, you're gonna wanna... Yeah, you need some practice to... Right, and you know what's up and down and what's left and right. Yup. So folks, you will have the ability to swap it into code so you won't have to re-solder anything. Just easily change that in the code. I'm sure there's drawn the Adderford logo very horribly. Which other people do like the Flight Simulator who is really good at inverted controls. So, I can't wait to see people posting cool Mona Lisa drawings of that. That'd be cool. Yeah, it's open. I think there's like a Mona Lisa of like Figment the Dragon. Yes, there is. One thing that's kind of, I don't like about this display. It's basically like a mirror. We were looking at like the matte screens to put all of our screens for when we're filming. We don't have like the blockers and the bouncers and the bouncing the light everywhere else, but the screen and the polarizers. So folks, the origin story here is the, look at this artwork. That's what I was gonna bring up. Yes, this is an existing learning guide. You can guys check out right now. Right, now we steered away from using this OLED because you kind of have to desolder a surface mounted resistor in order to get the spy connection to work. And we use spy to get this working. I believe it's spy. Yeah, I think it's a spy. Yeah, yeah. But yeah, this is a kind of an older guide and Carter did this several years ago. When did he publish it? 2018. Oh, you know, four years ago, no big deal. I know. It's crazy to think that Circuit Python has grown so much. Not just Circuit Python, but like the learn. We now have the ability to learn repos and have display IO that's gonna work across all of these types of displays whether it's OLED or TFT. Pretty cool to see this. And I'm happy to like kind of find this as an archeologist dust off the thing and be like, hey, we need to get this going. We need to make this a nice project. There's so many projects like that and learn when you go through there. Yeah, I don't like them telling us like, ah, that's already been done. Let's not do that. No, if you need to redo it. When you look at your, To refine it. You're on this day, we're usually like two, three, four, five, eight years ago working on the exact same project. Just completely different, you know. It was no Circuit Python, it was Arduino, now it's Circuit Python two, now it's five, now it's seven. So it's like, we get to keep revisiting these projects with updated code, updated platforms, and of course, updated modeling techniques and filament. It is a question on the discord asking about any way to reduce shipping costs to Europe. Yes, we have distributors all over the world. Have the distributor pay for the shipping and you can locally grab it from them. I just posted link. It is 804.com slash distributors and we are all over the place. I can't even count how many distributors there's so many. If you ever look at any of the behind the scenes videos of like the factory running and all the people shipping, this is where it's all going to all over the world. Yay. It is quite a scroll on all of the distributors. Definitely check that out if you are outside of the US. It's been some CAD stuff here folks, drawing some components for next week's project. My brand new CAD thing. There's a quick question from Mark Gambler. Any idea why my Ninja Flex is burning at some points? I've seen that exact same thing. The Ninja Flex sometimes tends to like warp or curl. Take the nozzle? Yeah, and that's what's happening. It's getting closer to the nozzle and the nozzle is burning, either burning it or you know how filament gets like stuck on the side of the nozzle. It's like rubbing off. So it could be like from the retraction. Yeah. It's the part itself. You know how like Ninja Flex tends to like sort of droop a little bit like one way or the other and as it's printing around, it's like sort of cleaning your nozzle. Maybe turn off combing. Is that what's going on? Like it's combing and some of the extrusion bits, some of the string is just catching up on the combing. Yeah. We try turning off combing and see if that's on or off. I don't, yeah, I don't know if it's like a default thing. I think you can do two. I mean, it's cleaning the nozzle, just go in there and clean it a little bit more because there's no way to avoid how the Ninja Flex like deforms as it's printing. Yeah. Mike P is asking about the, I suppose the potentiometer which is a rotary encoder. Yeah, these are not rotary encoders. These are potentiometers. So the potentiometer goes from like zero to 10, 24. So it can't go any further back and as you go, that's as far as it goes. So in the code, Parker has mapped, he's using map range. So he's mapping the X and Y coordinate to the potentiometers zero to 10, 24. I believe that's how he's doing it. So that's how it's able to do that. With a rotary encoder, you just go all the way around and it's pulses as opposed to like a fixed value. So I think that's why Parker used the potentiometer. Probably easier to code, I think. Yeah. Yeah. And then Mike P says, oh, so they do stop. Yeah, yeah, they do stop. They hard stop. Yep, yep. Think about like a volume knob. Like it's gotta stop at some point, right? And then Fomi guys has an answer on there. Thoughts on it. And Mark Gambler is saying, yeah, coming was enabled, he'll try turning it off. You might get some stringing from it, but it's okay, it's ninja flex. You can just cut it up. We always have to do processing meaning cutting off all the retraction afterwards. Yeah, yeah, it's like if it's spinning more. Yeah, it's just the nature of the knobs just look like they just keep going. That's another reason why I choose the knob is like when you have notches here, you would get confused of where I am, I think, because this one doesn't really need to know exactly where you are, because there's no real value there. Yeah. All right, that is this week's prototyping. I think this comes out next week, and then the week after the global stuff. Codes already on GitHub, if you wanna take a look at it. We have a Learn Guide repo where all of the code for our projects and everyone's projects are published. Cool. All right, let's do shop talk real quick. I got a CAD walkthrough of the Zoetrope and Zoetrope from last week. So if you wanna take a look at how I structured the design in Fusion 360 and how I'm using sketches and joints and external parts to create this CAD assembly and just showing how I'm using all those tools to get a visual representation of how these gears are engaging. It's about a half an hour of me bantering about CAD stuff and how I did this. Can I check out this cool book? Yeah, and then we have this really cool book. I recommend this book. It was gifted to me. It's called 507 Mechanical Movements, Mechanisms and Devices. And if you are just getting started with mechanical engineering, it's a great reference book. So for our project, our Zoetrope, there's actually some things here. You might notice this, number 34. That is the mechanism for the Zoetrope. That's a internally tooth spur gear and pinion. Basically the main takeaway here is that the two rotate in the same direction and with the same strength of the tooth gears are capable of transmitting greater force because more teeth are engaged. So that's cool. And then for the gear itself, number 40 here, you can see it's a double helical gear. Rotary convert it into rotary motion. The teeth of these gears being oblique give more continuous bearing than ordinary spur gears. It kind of self centers too when you have a profile like that. So it works out really well. But yeah, there's 507 mechanisms here and it's great resource for folks that are interested in mechanical design and engineering. So yeah, 507 Mechanical Movements. I've always wanted this book. That's this week's shop talk. A cat tutorial and a book recommendation. Trying to answer Leon's question or response on the distributors. They tried the distributor website but it's a lot harder to find things than on the Adafruit website. The other suggestion would probably be Digikey. How are they shipping for the stuff you're looking for? Apparently this is a website too. I just have Mike P. Thanks, Mike, for sharing that. The Mechanical Movements is also on the website here. So if you want to add free and print copy and bigger photos, you can look here. Oh yeah, there it is. I think they show it animating too, look. Yeah, I remember seeing this actually. I completely forgot about this book, so I'm sorry. But it's cool that they kind of have this. Yeah, this was really cool to see too. It's great to see it in motion. Oh yeah, can you see the index here? Yeah, look at that, the angle pressure there. Very nice. I'm hypnotized. It's so funny to have a real 3D model of it and be like, yeah, yeah, do it the whole day long. Very cool. Good pick. That's 507movements.com. Yeah, Mike's piece is great for animation. It is, yeah. Yes, the lawnmower is back. We had hope they had switched their schedules since they weren't here last week. That's just a special day. All right, folks, you ready for community mages this week? It's very koi. This week is, this is really cool. I think it's a koi fish. It's this quantum filament printed flexi fish. I don't know what I'm showing you. Oh, there it is. I'm not showing you the thing because I'm getting the link up. So the flexi animal craze is still going strong. Flexi animal craze? Yeah, doing like the rose dragon, the spiky dragon. Like my favorite, the fork, the flexible fork. Flexible fork. Like the un- This is fantastic filament. It's a quantum filament for matter hackers. It's got that two tone. This is printed with that. So you can see one side is this beautiful pink. The other side is gout. It's such a great color. Like the fish actually have those like pinks and golds. So it's really great. Print without any supports, prints in place, articulation. Kind of see how it's like, like the filament got twisted while it was going in and then it untwisted itself and fixed itself. So you're gonna get those if you're not careful. This is the time lapse. Really? Normally time lapses look gross, like the print. This does not look gross. No, you can kind of see where, like gross. Yeah, where it attracts. It was over for like, I don't forget how many milliseconds it is for that long exposure. Very cool. Man, this filament is trying to get. I know, it mesmerized by the Quantum Matter Hacker's filament. The modeling of the scaling is excellent. The face, like, so this is really good. So this is by Wild Art 3D. Is it designed to be, yeah. Is there, is there a handle here on Colt 3D? It's a paid download because it's a fantastic model. It's $1.69 in the US currency. Oh, there were some photos of it. We like fun things. I'm sure the kids will love it. Somebody in the comments of the video was saying to add like a motor and some fishing string to make them move or embed the magnets in there. Like we did with that little fishy magnet thing. But yeah, the movement on it. Excellent job, like. Fantastic model. Yeah, you have movability in it and you can kind of see how it's like sort of like a chain link the way that the sections are connected. Oh, I can barely see. It's like a 45 degree like draft and that goes up so no supports needed. And again, yeah, you can get some twisting in the Quantum Filament. So it's got to be some sort of like filament guide where it like keeps it like at one from twisting. There you go. But I'd print something different that wasn't a dragon. Yeah, so there's fish again. Oh, hey look. I'm close to reading a lot. You can move just his head. Oh, he's switching. Okay, so I'm now, it's eating, it's got some bait, some kiwi, kiwi bait, I think. Cool, so check out the model if you wanna support the artist, you can download it. And make your own fish. There's a bunch of other ones from the same person, I believe. The same person makes all of the flexes. That snake is cool. There's that dragon. Yeah, very cool. I wanna do this one next. The flappy dragon looks kinda cool. Flap the dragon? Cool. All right, we got some other community makes. So let's walk through those. This one just came in in the morning. Hopefully it loads, it only gets louder. This is the Chief Tusken Raiders staff. Whoa. Fantastic print from Fingerverse user B Cotton 81, just posted this up. Looks fantastic. It barely fits on that dining table there. Look at the filaments, freaking fantastic, huh? Where's that next button? There it is. Yeah, and the person says, I honestly saw this and thought it would be good indeed to burn through some silk filaments that I've had laying around forever. That's why it's not color accurate. I had two other copper pipe parts to make the full length of my nephew broke it. Oh, my nephew broke it too. It, your son, I made duplicates in different colors. So once I settle on a final version, I'll glue it because from, so it doesn't feel fragile to breaking at the screw ends very quickly. I would say over 40% infill and no bigger than three layer height if you want to keep it modular. Well done. It's surprisingly big and substantial feeling once assembled even at the reduced length. The fact that it's so modular, I might try to scale it down to kid size and they can pick their colors. Didn't that print it on a cruelty? A little one? We'll have to re-watch this again, perhaps. Yeah, it looks better than mine. I kind of say it in that silk filament, it looks beautiful. Print it on a cruelty, ender three. Use prims, fill the longer pieces, 0.6 nozzle. Ooh, that would be real nice. I'll speed it up for sure. Oh yeah. Now 0.6 nozzle is my favorite one. Very, very cool. Shout out to B-Content, 81. That's so funny. We used to play around with all the nozzle sizes and the two look extrusion. Oh yeah. It's like meh, one color, 0.4 nozzle. That's why the Maticus Quantum is fun. You get those two tone colors there. Here is a make of our infamous unicorn horn that's printed in flexible filaments but also PLA in, here it is, Luke posted this up. It's unicorn part of time. It's cool that there are holes in there for a string. Yes. I printed it with the color change filament. In reality, you can see much more transition than the pictures, but I should have printed more of the simultaneous to see more. I'm trying to use something. That looks orange, yeah, looks great. Even the tips where it typically can deform because the heat zone is all in the same area there at the top. People love these unicorn horns. They're great for the kids. I don't know, I think we have to revisit it like everything else but make them Godzilla scales for the back because the child is all into Godzilla now. This is super cool. So think of our scissor Tiffy HH posted up there, pie, badge, thermal camera with some of their own additional things to it. Take a look at the surface on this. This is one of those perforated beds. It gives it like this composite carbon fiber look to it. It just looks fantastic. So yeah, you can see here in the PCB mount. Pager, take a look real quick. It really looks like carbon fiber, but it's not, it's just perforated bed. We've seen those before, but yeah, this is a cool way to make a DIY thermal imaging camera with the MLX90640 thermal camera sensor in the Adafruit Pie badge. These 3D prints parts house the pie badge, the module, a battery on off switch and a little button for reset. I believe that's what it is. The front cover exposes all of the buttons, this display, there's also an external, the frame bezel that gets super glued on top of the back cover and you have some holes that expose the neopixels. I really love this project. I had a lot of fun designing it in Fusion and it's great to see folks actually make it. So a huge shout out to Tiffy HH for posting up there. Awesome build, thermal camera pie badge. Okay, we've got another one. This is a very fun one. There's another prop. This prop is from Final Fantasy. This is called a gun blade. Pedro created this in 2015 and the photo, look at that. This is printed in that silk filament, I believe. Prints in two pieces. Really, really cool moving barrel. The barrel actually rotates. The backwards barrel. Oh, that's right. The barrel is backwards. But very, very cool. This was posted up by Lord. 814, looks great. And this was printed on a CR-10S cruelty. Super fun project, made it for my friend who loves Final Fantasy 7. Really satisfied with how it turned out. Yeah, me too, looks great. And they used Sunloo PLA Silver. That's cool. There's three more there with me folks. Last week, we didn't have many. This week, everybody posted stuff. Yeah, it was great. I'll pause it. All right, this is a little snap fit mount for your circuit plate and express or circuit plate on Brute Flute. This was posted up by Thanks. Thanks posted up there. Their make up of this really nice bumper. Yeah, I think it's so many uses. I didn't know you could put it on upside down like that. I did not either. I normally flip it the other way, but when you make it symmetrical, it can go either way I guess. That's news to me, it looks great. There's those two extra mounting holes in case somebody wants to add something else. That's what that's for. Yeah, that's what that's for. It's usually for the base. I do normally just like that. Yeah, I guess you could flip it around. Cool. Yeah, there's different. I use this a lot to just stuff this under an existing decoration just to give it some light. So it's nice way to kind of mount this to something else in its very low profile. But yeah, you can make this version if you want to strap it to something else, attach it to something else. Yeah, and the clearance on the bottom is for a little bit of battery. A little battery, yeah. Yeah, and folks have made their own remixes and stuff, I think, so that's cool. All right, and then let's keep moving. We have two more. This is another prop, it's a prop week here. This is a TVA, TVA time stick from the Disney Plus TV show, Loki. So this is a little baton with some feather, prop maker feather wing. So Thingiverse user, the director posted up their make, they did some post-processing as well. Some of the photos are a little difficult to kind of look as they're, it's like a quality shot. Yeah, Thingiverse, like something happened. Yeah, there's a good photo of it. Looks great, post-processed like that, all nice and sanded and painted. I like that weathering look, it looks like a light saber, I'm great. Yeah, super cool. I'm always jazzed when I see somebody do the sanding and the painting. Yeah, because it takes so much time, I don't know how difficult it is. I'd ever get to know. Time consuming, it is. Loving this print, currently working with the wiring, but until now it looks amazing, it did one modification, we'll post up their makes. Cool, very nice. Again, that's the director on Thingiverse. All right, we got one more. The director for Loki? The director for Loki? I'm surprised they don't sell that at the Disney parks, a baton. They have all these other wands and swords and, yeah. A bubble wand. A bubble wand would be great. This is posted up by JBeerCat, GBeerCat, bear, GBeerCat, on Thingiverse, posted up their modification of the Clue case non-wearable. Yes, so if you want to- I thought- Clue case without wearable. I've made a non-wearable version. You probably did, but it was a different style. People do their own fun things to it, so. I don't see any photos of it posted, but maybe they're printing it still. So I'm trying to- GBeerCat posted up their thing. This is a version of the Pylon Clue bike case, but instead adds a freestanding non-wearable unit. The reason for making it is to create remote control for the shared gain timer that could be passed around on the gaming table. Cool. The main difference here is the original Pylon case is removable of the mounting holes in the back plate, the walls, corners, and the floor have also been thickened to improve reliability. Cool. And they printed out on a Lowell's VotTaz 6. Hey. GBeerCat had two real estate. Oh, that's why. He was using a 0.6 millimeter nozzle. Mm. Oh, wow, look at that. These are even better photos. Oh, there are photos. They just weren't added to the bucket, cool. That's cool when you use a- You also have a button pusher for the reset button. I love doing that. It's a really good technique. I think that's where we started using it. It's like the concentric pattern on the first and top first layer. Very cool. And that is this week's Community Maze. Thank you everybody so much for sharing your stuff with us. It's really cool to see folks making things. And everybody out there, keep posting and keep making. They were cells, me, and blocker, and download files. So the team noticed this, sent this in, PT sent a letter to Thingiverse themselves. So the PR team- Hopefully they're having a meeting on removing that. Hopefully, keep our fingers crossed. Because although, you know, we use all the other sites as well as our own. We upload all the STLs and the step files to Brackley to learn. We're hosting them on- We've been hosting them for a long time. The GitHub has all of our 3D models on there as well. And beyond Thingiverse, it's on Prusa, Colts 3D, My Manufactory, PinShape, Is that still around? Yeah, it's still around. The Ultimaker one. Imagine. Imagine. It is everywhere. All of our stuff is everywhere. So we don't really- And it's weird because we've never noticed that our ad blocker is on our router. It's built into the router, the ERO, E-E-R-O routers. So we never see, we haven't gotten that message yet, but we have seen lots of people posting about that. So there are some discussions on, you know, what to do in terms of- Yeah, I think PT will talk about it tonight. Yeah, we're gonna talk about it in our meeting as well. Right, so what the action them going is, but yeah, he has emailed, think that MakerBot Thingiverse to see if they can stop this, because it's not really good for them. Yeah. We have plenty of other places we can go. Right, it's just the bummer that Thingiverse wins when it comes to traffic. And if you noticed, all of our makes are unfortunately from Thingiverse. People are just posting them there. Unfortunately, the whole- I was trying to promote Prusa more, but probably not a good idea to favor one over the other. This is the conflict of interest I want to get into. And so what are we gonna promote? Oh, the file's on an online site. Stop going to Thingiverse. Stop going to- I can't say that. You can get them where we want. It's unfortunate, because that's where I get all of the blog content. Like if you go to the Thingiverse RSS feed, ooh, it is a fire hose. People are uploading like- You go back- Yeah, you can go back there every hour and see frickin' so much stuff. And it's not just dedicated to one what is it called? A Curise thing. It's like so many little pieces and bits for things all over the house or the tools and all these holders that make it so- This is what the reprinting was supposed to be about. That's what's kinda hard to completely shut them off. But hopefully they'll do the right thing. Yeah. And yeah, they're, I think, because it was during the pandemic. You mentioned much money they were making from all these ads, like every single ad. Like if you look at their numbers at Thingiverse, like on a normal day, it's about 400 downloads a day. That's average too. So if every one of those has a link to Amazon, to Premiere, yeah, like buy this Premiere thing. But anyway, yeah, then they're in the middle of the pandemic. There was already chats on like, just our curated for the guides, all the files that we created for that. So that might get rebooted. No, no, maybe. Definitely not interested. So Deweyster, let's see if they change your mind. You'll hear more about it from PT and us next week. Yeah. So I hope they do the right thing and remove that. Yeah, that'd be cool. Just on the downloading part. Sexy, you have to view it. Yeah. Or you can't have an ad blocker. Yeah, I know. I don't know if you notice like when you're going through the makes things, do that show up? They do. No, they do. They certainly do. They're Google ads. You know, sometimes the wrong ad will show up and you're like, I can't show this. Whoops. All right, I think that is going to do it for this episode. Yeah, that was a community make plus shop talk segment. Fun. Don't go anywhere though. Tonight we have Ask an Engineer. I'm sorry, tonight we have first show and tell. So we invite you to come on show and tell. Hope to see you folks there. We'll be there this week. It starts at 7.30 PM Eastern time. You can hang out in the Discord server when the link is pasted there. You can join in. It's a stream yard kind of live stream event. So you can join in that way through the Discord server. And then shortly after it's Lamar and Phil doing Ask an Engineer, a full hour of Lamar and Phil doing open source hardware news, new products, chat about things that works and more. And then so yeah, we hope to see you tonight. Aren't you want to tell? Hosted by Mr. and Mrs. Lady Aida. Tomorrow, John Park's workshop every Thursday at 4 PM Eastern time. Come hang out Friday. Come hang out with Scott. Deep Dives with Scott every Friday at 2 PM Pacific or 5 PM Eastern. Is for me that I do it? Not yet, right? He's not taking over this one. Soon, I think Scott has three or two more episodes left. Until a little short leave or maybe. Okay, cool. Lady Aida happens on Sundays from the desk of Lady Aida. Mondays is the circuit Python meeting. Great opportunity to tune in to the folks. Every Monday at 2 PM Eastern time. JP's product fix of the week are on Tuesdays at 4 PM Eastern time or 1 PM Pacific. You get up to 50% off coupon things. But only during the live show. So you got to tune in live. In that wrap it back around. We do this show every Wednesday at 11 AM Eastern time. Thank you everybody for joining us. We got to change that picture there in the Taz. Oh yeah. I just like, it's almost like the retro. Like having a retro floppy or something. You mentioned a 3D printer that has a floppy drive. And it's like printing off the floppy. Oh my God. Why? It's been so many years. It took years to print. Cool, everybody thank you so much for joining us live. Hope you have a good week. Good luck on all your makeup endeavors. But until then, remember to make a great day. Make a retro great day. See you later tonight. Bye folks. See you tonight.
