 the first one of 2021. Welcome to the show. My name is Noah Ruiz. I'm a designer here at Adderford Jodamira Weekes. My brother, Pedro. Good morning everybody. I'm Pedro Ruiz, creative tech here at Adderford. And every week we're here to share 3D printed projects featuring electronics from Adderford. That's right. This is where we combine 3D printing, dual electronics, CNC milling, a bunch of maker stuff to inspire you folks. Hello everybody. Welcome to the show. Welcome to the new year. Good morning. Good morning. We're hanging out in the Discord chat rooms. If anyone likes to shout out, say hello. Good morning. Welcome everybody to the Discord chat room. You got a couple? Yeah, yeah. Good morning. Good afternoon. Good evening. Good night. Everybody hanging out all over the world. Thank you for joining us this morning here. Yeah, we got our noise, our noise going on. So everything's, hopefully we'll go smoothly with the show. If you'd like to join the Discord chat room, that's how I start, right? Me too. You can go to the discord.gg slash Adderford. That's the invite URL so you can be a part of the group and community. Shout out everybody hanging out. We got... Shout out to everybody hanging out. We got Charles Benafor. We have Christian at coding. Hello. Style tech. Paul Cutler. Do Wester. Do Wester. Hello. Style tech. Typing in. Hey folks. Thank you for joining us. We will get started in just a few moments, but we just wanted to welcome everybody to the show. Let the stream kick in into gear as we broadcast live from Florida, Central Florida. That's where we are. Cool. We got some fun stuff to share with you folks. So yeah, let's jump in with the housekeeping and feel free to add those messages and things, questions throughout the show. So let's go ahead and take a look at the freebies going on. But first, just give a little bit of a warning. You'll notice there's a red banner at the top of the website. There are some delays expected. We're waiting on things. Everybody's waiting on things. So please be patient. If you put your orders in, it might take one to two business days just to process your order. There's lots of stuff going on. So hopefully... Is the mic on? So hopefully, you'll soon get your things, but please be patient. So if you order things that are $99 or more, we still have... Oh, we have a black feather now. The pink feathers are also down. Thank you, everybody, for getting those very special edition pink feathers. Hopefully maybe we can make some more. We'll find out later tonight, I think. For orders that are $149 or more, we still have the StemAQT boards. If you have an account with us, make sure you don't get the same one twice. You don't have to do anything in your in your cart. It just gets automatically added. For orders that are $200 or more, you'll get a StemAQT board, the black Adafruit Feather RP2040, and free ground shipping for US continental only. And then the last tier, the mega top tier through 99 or more, you'll get that free shipping, the free StemAQT board, the black Adafruit Feather RP2040, and a Blue Fruit Circuit Playground, our favorite NRF 52-840 board with lots of LEDDs and sensors and lots of demo projects to get started with on that one. So there we go. It's for a limited time as supplies last, and hopefully we get those new pink feathers. Hitting on over to the jobs board, help want it. You head on over to jobs.adafruit.com. You'll see there's some new postings. I'm seeing two of them since we've done the show. It looks like there's a posting for an audio circuit. It's a contract. I think that might be remote. We have a remote instructor for summer engineering program at the Blue Stamp Engineering in the San Francisco Bay area. Check that one out. Those are the latest job postings. You can create your profile for free or post up a job if you are looking for someone to help you with the projects or if you're looking to employ some new folks. So you can always check out jobs.adafruit.com. Okay. Every Monday at 2 p.m. eastern time is the Circuit Python meeting that happens with the core devs and the community. You can join in by hitting up the Discord server and you can also listen in on the archive, which is posted maybe a few hours after. But every Monday at 2 p.m. you can check out the Circuit Python weekly. Newsletters happen once a week. You can check out adafruit.com slash newsletters for product focused stuff. If you want to know what new software add to the shop, you can subscribe to the newsletter at adafruit.com slash newsletter. And then for daily adafruit newsletters, you can go to adafruitdaily.com and subscribe to all the many categories such as Python on hardware. I think we're slowly approaching 10k subscribers to the newsletter. But shout out to Ann and PT who have been doing newsletter. And if you want to get your stories, projects posted and featured on the newsletter, you can do so by hitting up CSP at adafruit.com to email address. And that is all the housekeeping, I think. Let me jump back over to the Discord chat room and see if anybody says hello. Oh, sweet. Phone me, guys. Thank you so much. That's a fog report for some CAD stuff. Yay, the RP2040 model is a big integral part of the project he's working on. Yes, that's great. Yes, there will be more CAD parts. We know there's some new boards. And I definitely want to get the QT Pi ESP board made. Yeah, folks. Yeah, ESP ES2, right? Yeah. So that's on my list to do. Got some new hardware. I think there's a new GPIO expander. And there's still some requests to take a look at in the backlog that I have. But yeah, shout out. Phone me, guy. Anytime you have any request, probably do a GitHub issue. You can add it there. And you can tag me. I'm DJ Ekken. And I get notifications, so I'll check it out. And then we have a comment over on the YouTube. Someone was asking, Christian's asking, the equivalent of adafruit in Romania. We do have distributors there. You can find that on adafruit.com slash distributors. And there is one down in the Europe area. I can see one is in Romania. Yeah, all the way to the bottom. Optimus Digital SRL and Robofund. If you guys want to see all of the other distributors all over, check out adafruit.com slash distributors. Yeah, I'm here. You can see a giant list of them there. Robofund sounds fun. And Optimus Digital SLR, like you said. Very cool. I thought there used to be a map as well. If you scroll all the way up, I think I posted the anchor tag, where it cheeks you down there. Oh, wait, no, you're right. There used to be a map. No, there was a map. We have a nice list though. You can just search for Romania or scroll. Cool. Excellent. Yeah, the list works here. You can just search. I was able to just browse and say Romania. It says you can't access the link. What was it again? Just adafruit.com? No, no, no, the actual Romania one. Maybe if I just directly... Which one? He says those are the ones that they already use. Yeah, I mean, that's where we ship those, all those products. And again, there's some delays and things going on with the weather and some other things. The product you're looking for is not there. Definitely request it. Yeah, and you can try Digikey as well. All right, let's go ahead and jump into this week's project. Okay. Take it easy and start off 2022 with these awesome ELF earbuds. Whoa. So a lot of the projects that we come up with, this was Lamar's idea. She found a nice little trend on Twitter. These ELF earbuds. Yeah, these look really cool. These are some ELF earbuds. They're like BLE wireless earbuds. But the thing about them is they're kind of built in, these little ELF ear add-ons are built into the headphones themselves. So they're a little pricey. If you're going to get wireless earbuds, they're going to be around $100. And these are really cool looking. Lamar thought it'd be cool to print them out in some different colors. So that's kind of what we did. But we wanted it to make it so that you can put your own headphones into it. So we like these earbuds and we figured we'd kind of design it around this style of earbuds as we see them. Many different manufacturers make this style of earbud. Yeah, so these work in PLA, Ninja Flex as well. So I really like the flexible ones. And like you were saying, these are compatible with the existing earbuds already have. Of course, we give away all of the design files so you can edit this to your liking. And one of the things Lamar wanted to highlight are ELFs come in many different colors. So we have all the skin tones that Ninja Flex makes here. So from here, I think this is Carmel to Chocolate to I think Peach Smoothie. I think is the one we still have in stock. Or if you want to go all Pandora Avatar or whatever ELF that has like these pointy ears, you can go with these sparkly purple ones. Like you were saying before it works in PLA or Ninja Flex. Of course, you'll be able to do a nice assortment of little bendy stuff with the Ninja Flex ones. You could mold these as well with PLA like in hot water or something. And the cool thing is that these go right directly behind your ear. Nice and comfortable and stay input. And the main reason why I started working on this was because one of my earbuds went right through the wash. And just for anybody curious, it's $80 for one of these. My right apple ear pods. Yeah, my right set came out just fine. I went to go put in my other set, hit play. And there was a bunch of water in my ear and that shorted out the other earbud. So you can't get replacements. One should be here today. But yeah, I don't think this would have happened if I had my ELF ears on. I somehow stuck these in my pocket and would definitely have seen that in the pocket before I threw it in the wash. So definitely. And that's just a comment that I keep hearing over and over again. Yeah, good way to keep them from being lost. Yeah, they can get lost sometimes. Yeah, so the edible parts about this is all Bezier curves. You can adjust it to whatever your ear shape is. And of course, the diameter of whatever ear pods that you guys are using. So these print without any supports. You got a nice flat bottom. So you have plenty of adhesion to the bed. Not much to worry about there. So it's a fairly simple print. You have a little bit of overhang here, but it tends to catch itself. You have some good active cooling. But yeah, when you're printing with NinjaFlex, it can be a little bit challenging, but definitely give this a shot. You can see here, it becomes a little stringy, but that's kind of okay. We just kind of left it like that because it's fine. But you can clean that up with some flush snips if you want. I just leave it meant to increase the tolerance so that as a nice little grip to the. So that's typically what you'll get if you turn off your attraction when you try printing NinjaFlex. Do you still have that set like that? Yes, I do. Okay. And this was printed on, I believe, a Bowden or a direct drive? No, this is a direct drive. You can get the Bowden's to print if you're printing at like, I don't know, like 20 millimeters a second. That should be okay. Now when we print NinjaFlex, you tend to print a little bit hotter, right? Are you 230 or 240? For this one, 240. I think you could get away with like 230, 235. Yeah. But yeah, this is the 1875 diameter filament. You can see here that you want to be real careful with your first layer with any print. You can see here, you get a little bit of an extra thing there. But what kind of bed did you use? Just the powder coated? Powder coated PEI. Just make sure that it is not squished onto the bed to make it easier to remove. Make sure that your bed is heated to I think like 50C. That will allow the removal of NinjaFlex a little bit more easier. You could also use blue tape as well. It'll make it super easy to remove. You just get like a texture on the backside. But if you like the PLA and you have lots of PLA colors or PETG or whatever, hard or plastic, should be pretty, it'll be a lot easier. You don't have to clean anything up here. It looked really, really good there. Yeah, a quick question from Paul Cutler on the Discord asking, NinjaFlex is like TPU? Yes. This is the shore hardness of 85A, which is pretty flexible and it has a nice grip to it too. These would work just fine with SemiFlex or the 90A, which is like the typical TPU that you will find all over Amazon. Not as flexible, but we'll get the job done. Yeah, for sure. This is very, very floppy. What helps it stay, it's reduced. It's like against your ear. That kind of keeps it upright. You can adjust it here. It's got a tapered edge. So if you look very grossly, the circle has a bit of a taper so that it can catch onto the little stem of these ear pods. These really look like those Q-tips. Remember the joke about these Q-tips in your ear? Yeah, but as you saw there, we didn't clean any of this up because it's NinjaFlex. It's so forgiving that you just press it in and it's just like, whatever. That's really nice. You can see all that messy stuff. You can clean that up, but like I said, Pedro said that it increases the tolerance a little bit, so it gives it a bit more grip. But yeah, the NinjaFlex TPU, it's not just flexible. It's also grippy, so it has a nice feel and grip to it. So if you were doing like a gasket or rubber feet, NinjaFlex is always a great option to use if you want to print something custom. What else can we say about it? It's a little bit stretchy, right? It's a little bit elastic. You can see me. It's actually TPE. I lost all of that. Okay, it's TPE. TPU would be like semi-flex, right? It's a little bit more. It's less elastic, but still flexible, I think. But yeah, you're going to find way more colors in TPE for NinjaFlex. Let's go ahead and look at the website. We stock a good amount of NinjaFlex in different colors. We have a category that's something we have, but we have black, white. This right here is that almond peach smoothie. That's that kind of peach color. We have some other ones like orange. We did sell out, unfortunately, of the caramel. I think that's the one that matches my skin. Yeah, unfortunately, they are discontinued. So we're kind of trying to get these off the shelves so that NinjaFlex is hands. So you can see here, yeah, the caramel candy has been discontinued. And unfortunately, you can't get this. Fennard Drives is the manufacturer. I think they only have a couple of these. And I don't think they make them anymore. Yeah, their main drive behind it was the prosthetics. So they were doing the skin matching with prosthetics, like the grippy parts on the fingertips. Yeah, we used to carry it in three millimeter diameter for the Ultimakers, but we don't anymore. We either sold out or we just can't get them anymore. So it's kind of like well supplies last, right? How that purples out as well. Oh, no. Yeah, that is wonderful. There are other manufacturers of TPU. You can find some stuff from SandSmart, but we're really kind of big fans of NinjaFlex, but it is what it is. And there is still some spools out there if you want to partake or if you have an old spool of NinjaFlex, you're meaning to try something out. Maybe this interests you. Let me focus again. There we go. One of the things you can do too is grab some of the weight NinjaFlex that we have in stock and airbrush it. Yeah, do some clown matching that way. Yeah. But definitely really cool for, you know, if you're doing your baby Yoda costume or your elf. That's funny that baby Yoda would be kind of cool, right? Yeah. Put it in this nice green. Cool. All right. Well, I guess let's take a look at the learn guide, shall we? Let's jump in. Super simple, two pager, just explaining the project itself. Yeah, we got a nice video so you can check out. I wore them. They fit my ears too, which is nice. Probably a good fit in the behind. Yeah, mainly, yeah, I check out the stuff. Is this? I'm just looking at the price difference. Like, why is one different than the other? Is it the color? Might have been the color, yeah. It's the color, yeah. A little bit pricier. But yeah, this is a pretty good price for like kind of your standard black color. Normally, they're 50 bucks. So we got a good deal here if you want to pick up some Ninja Flex. Also, you can get a 10% code tonight if everything goes well. I'm just grabbing all the links for this. Sure. And then the other page is just showing the 3D printing for this. Just showing the settings that we used for the... Sure, you got download links. So if you want to download the Fusion 360 file and you can also preview it in your browser, you can get a good look at just the model if you want to just kind of rotate it and see how thick it is. You have the full sketch that you can download up here at the top corner. There's a download button. If you download the step file, it should work in most CAD packages. You also have OBJ and FBX and some of the other ones. I'm familiar with step. Most of the CAD packages out there will work with step. But we do have the STL files as well, uploaded to Thingiverse, PrusaPrinters, and the like. But yeah, you have full access to the sketch so you can modify any of the geometry here. The diameter as well is one thing you probably want to take a look at. But yeah, this is a good kind of small, medium print size that you can kind of prototype different iterations to get the fitting just right or the shape. It took quite a while to get the shape while, yeah. Okay. So yeah, just basically got an interface settings and then you can, of course, print it in PLA. We got the settings for that. Super simple. No supports. And yeah. Yeah, it's a good print to test out that Spold Ninja Flex has been sitting around for years. I think everybody has one. Everyone has a Spold Ninja Flex sitting around. Cool. And there's lots of fun shapes that you can play with if you're new to Fusion. You can kind of get a feel for how the Bezege curls behave. Right. You could delete geometry and things. But yeah, okay. So we do have two different versions. If you go to the overhead, where'd my other one go? Oh, here it is. The difference really is how far down the little curved shape goes for putting behind your ear. That's only because of the differences of, the third gen pros have a smaller stem than the second gen. Okay. So you want to be aware of the shape and the length of the stem on your earbuds. You took that and depending on if it's shorter or not, you'll want to change the shape. Okay. Cool. Yeah. So you just mess with the Bezege curve on here, depending on how your ear shape is and how long the stems on your earbuds are. And you could, of course, inside the timeline of Fusion, if the little, let me call this thing, little cylindrical holder hoop thing, if you need it to be a vertical, you can rotate this guy around and have it be like that. So that it goes on the top part of your ear. If your earphones or headphones, your buds are in a different shape, you can totally update that. There is a left and a right. So they are a mirrored STL. They're already mirrored for you. But yeah, they should be mirrored, because that's the way it fits your ear. You can't afford to just print two, is all I'm saying. Don't print two left and right, and they're marked as such in the STL file name. Correct. Cool. And that's pretty much it for these customizable earpods. Yeah, some quick settings, you know, 230 to 240 C on the extruder. You have a thicker initial layer height. Normally it's 0.2, why is it 0.3? Just the way that the flow is for the image flux. Okay, just so I can do a little bit thicker on that first layer. Yep, it's just so that these close up. Just so that everything fuses together. And again, that is depending on what printer you're using too. You might not need it. You might need like a 90% for the initial flow. One thing we do is we slow it way down. The first layer speed, you want to slow that way down so that the nozzle has plenty of time to lay down that nice perimeter. So it has good adhesion to your bed. Knock, knock, knock. Trying to switch camera. Okay, 10% infill doesn't really matter because this is a solid layer. You're going to get solid layers for the majority of these. So if you have like six tops and six bottom layers, I think five should be sufficient. Five should be sufficient. Okay. So there's no infill really, it's all perimeter, right? So what's the thickness of this guy? Probably like, I think like a millimeter or two. One and a half. Yeah. But yeah, they're all solid top and bottom layers. And there's probably a little bit of infill here. I think it, whatever it said, 10%. So not a lot. How thick do you think this is? And can like two millimeters, three millimeters? This is, I got fusion here. I'd open it. Six. Six millimeters. And again, that's all depending on how much, how much you need for your specific earbud. Wow. It's six millimeters tall or thick? Thick. Wow. I would not have guessed. I can't rotate with no mouse infusion. I should have had you open up the file before. I think I still can't. I'm sorry, it's three millimeters. I'm looking at it. Yeah, I was going to say something like two or three millimeters thick. Yeah, it's three. And with that, you should have pretty good if you have your, your perimeter set to like three shells, three layers, right? Should be good there. But that's depending on how you want to do it. You know, that's, that's all for you. And if you're slicing in PLA, kind of standard settings to 20 C on our extruder point to layer height, same infill, a little bit faster, right? 60 millimeters a second is a safe bet. But when then to flex, we slowed it down to 50 millimeters. I would slow it down to 40. But maybe you have yourself a nice cruelty printer with a nice extruder. But that depends too. Yeah, at times we've had to print it at 30 millimeters a second. So I'm looking at comment here from Mark Gambler saying that he's tried ninja, ninja flex again, and it's still giving him troubles. It just doesn't have time to fight with it yet. It is. It is. It can be a little bit of a, a little bit of a fight. A lot of the times, like the best shape to print is something that just has a lot of, not a lot, but a good amount of surface touching the bed. Like if you're printing like a thin ring, that could be challenging. But something flat, like, like these ears is a pretty good test print, I think. You know, it also depends too on the, the, the material to the ninja flex. Sometimes like, I was able to print this with retractions on the Pete smoothie for whatever reason, did not want to print with a retraction on. So I just turned it off and it turned out fine is specifically because there's not a bunch of like islands or it's going. It doesn't have to attract a lot. It just, it's okay. And as we showed, it's okay to have a messy inner ring here. It kind of helped it a little bit. You could clean it up, but we did not because we just show you what it looks like off the print. There's no supports, but hey, you got this bit of string here, but that's just the nature of ninja flex itself. It's always going to be a little bit stringy unless you got like a really good upgraded direct drive. Direct drive is the key to get that something more rather. So it's the extruder, the temperature to try to 40 try. If it's like bustling, slow it down and heat it up to 30 millimeters. That first layer sometimes 10 millimeters a second is for the initial layer, that very, very first layer. And then you want it to be higher from the bed too. So for these, I'm at like 0.38 for the height. Usually it's at 0.2 for the initial layer height. So that initial layer height is critical. And then you can turn down the extrusion width or the flow. They all have different things. You can always see there's a little bit of something there. So it's not completely dead, but you should be okay. I'm just showing like how just the smallest difference will make something. But this is the surface that is out. So we will be seeing it. Was this printed on blue tape? No, this one just wasn't as like... Yeah, I think it was the flow is what I had to change on these because of the peach smoothie. So you definitely want to mess with that. Yeah, the flow, the how much materials being extruded out. I haven't seen, I haven't adjusted flow in so many years. And then that's part of the fight too to get Ninja Flex to work is figuring out what material settings you need to mess with, depending on your printer. You have cura open already. Where's the flow? The initial flow is right here. Initial flow is under materials. And for these, I had to drop it down to 95%. So initial layer flow. Under material. Under material. Yeah, you got to turn it on. I know. I'm about to show folks what I'm looking at here so you can see. Let me just do a full screen here. So I'm in cura. And if you're using cura, you'll get an idea of where these settings are. But under material, you notice I don't have it turned on. You kind of have to turn it on. You don't see flow. Just having flow on the search. Initial flow. Ah, there it is. Under material. Okay. So that's a good tip too. When you go to the little icon, you bring up the preferences, you just search for it. Because I was going to take a while to manually look through all the settings. And I think that Prusa Slicer, like all of the slicers have. It's percentage based. So you want to upgrade it to what, 110? No, no, no, 95. You want less. If it's buckling, you want less. Because what it's doing is it's trying to extrude too much at the same time and it buckles up and it coils around the feeder. All right. So you want to turn down your flow and not make it higher. Okay, cool. I learned something. I normally just use my PLA setting. That's so funny because that one little setting is what got everything to print. That's fun. I don't even look at it. So hopefully folks who you'll know, in your slicer, maybe using Prusa Slicer or something, I think they have a similar layer flow. Flow. Flow compensation for the first layer. The amount of material extruded on the initial layer is multiplied by this value. It's always nice to get a tool tip. Cool. Yeah, lots of little switches to look at. Cool. Okay. Let's take a look over at Discord. Close up the project, I guess. Yep, that's it for this week. Mainly it was a inspired, it's this cool way to combine flexible material, something practical. Like now you're not going to lose your headphones, right? So there's a little bit of practicality in it and you can make it whatever shape you want. So if you want something else to go on your glasses or you want something to go on your watch, Ninja Flex is always a fun material to play with. It's very forgiving when it comes to tolerances. The elasticity is really, really good feature and of course that grip is what you get. So all of that combined, it's kind of a fun little project. So hopefully that inspires folks to use their Ninja Flex and come up with some fun things for your existing gadgets, right? You don't have to get a whole new gadget just because it has an elf ear, right? Yeah. You got your headphones that you really like, make something for them. Exactly. So that's the spiel I got. And it's only, what, 300 something days till Halloween? So you've got all the time in the world to work on your next costume. Right. I'm sure kids will like it too. That's right. You're cross everybody. Let's go ahead and jump into this week's, what are we prototyping? Cool, I'm going to need some space. So let's get to space. So we've been playing a lot with with acrylic and this week we have a Zoetrope. So what is a Zoetrope? Zoetrope is a device that has individual frames and they're animated through a motor. So what we did is we got a DC motor. This is a little $2 motor. We 3D printed a double hearing hex gear and we have another gear and we're running it on a feather with a DC feather wing so that we can control the motor. Let me move this up more room here. So this is the main base of it. And what I wanted to do was to have this top cover be swappable so that we can take this out and add a different frame. So my idea is to have different top covers. So if you want more frames or less frames and what I want to do is experiment with some thinner material. This acrylic is a quarter inch so it's rather thick, a little bit heavy. So I want to play with some thinner materials of eighth inch material that I want to have in here. These tabs are all centered so that the light, the light in the neopixel will shine them when they're in motion. So I have this little base and there are three pieces here. We got a cover that kind of just keeps it covered. This bit here will actually keep the ring elevated. And then we have a separate holder here for the neopixel. This is those neopixel button PCBs. They're just a single neopixel with pads on the bottom. They're press-fitted into this little holder and you can see I have a hole there for the three wires to come out. So you have your neopixel three wires and two wires for the DC motor. So on the top of this here you can see that there's a little bit of a channel and down here you'll notice that there's a bit of a lip. So that's kind of how it hurts. There's no ball bearings. It has a nice, what would you say, it has good rotation. There's not a lot of friction going on. It's actually not really touching this outer band here. The only things that are touching is this lip here and this here. And if I want it even smoother you can probably put a couple drops of like synthetic lube. But so far it works really well. So you're wondering where's the gear right? So the idea here is that I have a little inner gear and this actually pops out. I'll just leave it in. But the idea is that the gear just kind of mates with the DC motor and I guess let's plug it in. So you'll need to plug in your feather and a power, an external power supply to drive the motor. If you want to make it easier you could use the Adafruit Cricut feather wing. That way you can kind of power the feather and the motor all with one power supply. But there's a lot of features on it. So here is the party parrot. Oh the angle here. Oh you can make it out. Sorry about the noise folks. See the parrot? I think one of my frames are wrong. Yeah. Okay so with lighting and stuff you know it's going to be it's going to be very specific. Like you're going to have to have some a little bit darker area to kind of get the full effect of it. But these little panels are CNC mills and each each one of these engravings is the one frame of the party parrot GIF. And one of the things to do is I added the numbers here just so I know which one it is. So here's how the tabs look like. So you got one two and they're all you know etched to have the little party parrot. That's kind of it really. Yeah so again I really want to get some more I'm waiting on some more thinner acrylic because it's easier to cut and there's more frames that I can play with here. I want to do 20 frame animations. That's why I have 20 slots here. And what else can I say about it? It's a little bit heavy because of all the material right like the acrylic all adds up to weight. But it seems to be okay. It doesn't seem like there's too much stress happening on the motor. So like I didn't I don't think I've stripped it. You can see the little neopixels on there. Yeah so hopefully we can have this out in the next two weeks or so as we work on it a little bit more and make a wiring diagram and everything and kind of run it through Lamar and make sure that everything is all squared and good with it. But it's just the game of the thing with a live show. You kind of have to rework your camera. Looks like about the same. Yeah there you go. Yeah one of my frames is off so yeah one of my frames is is like incorrect but that's fine. You could change the speed of it. This is all running circuit python on the M4. We're using the the motor library motor kit library to make it really easy to change the speed. Yeah I think is it this one? I think it's this one needs to be rotated. So they're really easy to take in and out of these tabs which is always a good thing so you can just kind of press fit them in and kind of make sure that your your frames are going together. I think that's better now. Let's try that out. There you go. And the effect is way way more prominent in person. It's kind of tough to to get into the webcam. No it looks like I can see it. Yeah it's hard to get this thing going on over the webcam. So hopefully you know next week we'll have the thinner material and more frames so we can have a better animation but that's uh that's what it looks like. That's what we're prototyping. I have a link to the Fusion 360 share design. If you'd like to download it now and play with it you can do so. It's open design. You can download it as a fusion file or step file which should work in most CAD packages. Yeah people like the SoTrope with a party pair of course. You got a question from Wolves on the YouTube saying or asking if you need a microcontroller to drive the motor. Will it work with a plain old electronic motor? Yeah these DC motors can be powered with a nine volt battery. You can wire it directly. We just want to have it so that we can have the LED on and change the speed. You can have a potentiometer wired to it as well so you can adjust the speed live and kind of fine tune the speed. That's why we have a microcontroller but no you don't need a microcontroller and the parts are designed in a way where you don't have to mount any electronics to the actual base here. I have it so that there's a hole in the outer casing in the outer frame so that you can just have whatever microcontroller or battery but this is the main base of it. You could probably fit an LED here like a bare three millimeter LED and have no microcontroller at all so I want you know folks to use what they have so if you don't have a microcontroller you just wire it up to some sort of power source but these little motors like two dollars are very cheap they're inexpensive. Neopixel is you can get a pack of them for like five or ten dollars but yeah a couple screws here because you know this all prints without any supports so you got your base your cover and then your inner frame your your gear thing here this just press fits in and out it's pretty tight in there so I'm just leaving it there for now. A couple screws right um yeah I really like these DC motors they're cheap and they come with these headers so they just plug in to the to the feather wing here um but yeah that's kind of how I gotta get set up. Yay wired anyway so that's what I'm working on. I want to do some more frames and things um yeah we'll uh we'll show you next week what we come up with. That is the Zotrop. Hopefully uh we'll get it out soon. Anyway we have a really cool link on the Discord. Susan has posted one of her cool LED lit animations from uh 2018. It looks pretty cool look at that. Is everybody applying back for you? I think it's stuck on my end but check it out it's on uh yeah it's like stuck on my end. Check out the discord at discord.gg slash adafruit for all the cool comment and banter going on during the chat. Oh cool. That was very cool. Looks like a uh oh it's kind of josh yeah wow that's awesome yeah so you don't really need that many frames to make a animation and um yeah that's really cool. Ah it's gonna trinket. Trinket that was great. Like how compact it is. Oh look the new pixels are um the actual bare pixels wow that's amazing nice work that's really cool yeah I like the tabs too on the 3D print. Pics and these in the other chat rooms too that's so cool. Yeah I like this effect. I've been so much fun with acrylic that uh that I figured let's let's have the acrylic moving but no it's really cool to have uh different different layers and if you've got a laser cutter or CNC mill it's always fun to cut up some acrylic to um etch some cool designs. Sweet. Well that kind of brings in into community makes. Sweet anybody feel free to share things and projects in the uh Discord as we're doing this? There's also a shown hill specific channel on the Discord so please post in there as well. Sweet okay well let's uh take a look at this week's time-lapse Tuesday every Tuesday we find a design from the community and we print it out. This week it's a really nice pencil holder it's designed in a way where it makes a spiral effect so if you're using colored pencils you can get a really nice kind of array of colors. Yeah I've seen this pop up a couple of times Lamar sent this link over and it's like makes something colorful for 2020 so this is really cool way of uh doing a nice little display of all of the little different colors of the rainbow for in my case for my kids being able to easily grab what color they need and make a mess and then draw all over the furniture. This was designed by Pete Owens on Thingiverse and Pete Owens posted this up as a free download. We used uh rainbow filament just to get that um that color changing gradient effect there's rainbow filament in PLA pet G probably and some other ones but this is that silky style. I know I should have used that well what is it the um the one everybody's been posting for Matterhackers? Oh yeah Quantum I think that's called yeah that'd be gray um so if you have some of that yeah try it out this is a fun thing and uh folks are saying they could also hold screwdrivers and other tools so not just pencils anything circular would work and it looks like the diameter's a little bit bigger than your standard pencil so maybe some Sharpies too. These are actually markers right but Sharpies have different oh yeah yeah yeah so all right here it is in the overhead. Yeah I should put that on there right and I think one of the kids already grabbed one of the markers yeah but yeah as you can see here the diameter is a little bit bigger for uh than what these allow but it still works nice simple little design and I think the only caveat here is that it takes oh man I forgot how long I have it listed there but it takes quite a while to print. Nice simple artistic uh what is it? Holder yeah here's some Sharpies and uh and a P-O-N's design so you can see here um yeah it's a prints with no supports um pretty good adhesion to the bed and this cool effect don't forget the cool effect yeah looks like there's a hole in the center so you can I don't know mount it somehow to your workbench if you want oh I thought it was for attaching it to a motor so you can just spin around oh you can do that it's a real loader very cool so uh yeah free download something reverse the barrel diameter is a half inch standard Sharpie marker size holds up to 13 markers I don't even know cool only uses 92 grams of PLA excellent all right and that's this week's time-lapse excellent job we have some other community makes that were sent to us uh during the break we have a few of them so I'll try to run through them hopefully we can get through all of them okay first up we have a make of the circuit cookie roller sv high on thingiverse posted up their make of our circuit cookie roller you can make cookies with a 3d printed cookie roller it has these imprints these impressions of uh of these circuit traces and we made some amazing cookies this year or not this year but the year we made this project in 2018 these cookies are flipping phenomenal look at that Adafruit cookie the detail all these cookies were just amazing and we actually have our cookie recipe in the learn guide look at the adabot that's so fun we had leds adabot and um whatever this is a cookie cutter not a cookie roller sorry but we kind of combine them to make not just the uh the texture in your cookie but the shape of your cookie these were so fun recipe is available on the learn guide yeah yeah i forgot the recipe yeah there was like a special thing that we had to do this this is so good i love the really golden yeah there was a like a specific thing you had to do for it to for the shape to stay i think it was like butter or something did we really have the oh yeah where is it probably assembly there you go ingredients oh wow look at that two sticks of unsalted butter yeah does this bring back memories better yeah i was about to say and can you tell that we really like our job we're always doing something different yeah this we were cooking learning how to make cookies and like getting the recipe like getting store-bought dough was just not it did not work we had to make our own dough because i guess the stuff can't work uh in the for the shape for the shape right you want you have to use this recipe yeah this is such a fun one so it's really cool to see at least one person in the universe made it i just hope they can make the cookies now because it's a hard thing to do i mean it got downloaded a couple of times so i'm sure there's other people that just didn't post about it and i remember people tweeting about it it's 2018 so yeah and look at the resolution too that you get at it yeah let's look on adobot it is so good yeah and i have to take the tutorial on uh how i made this pattern because there's a different method now you can just use the emboss tool instead of having to use the sheet metal yeah it just came out for fusion and we're gonna be talking 10 minutes about freaking cookie rollers anyway well it's the way that you create the pattern you know it's always about the design process of this it's just cool to mix and something physical like you get to eat it and then this like custom made shape it's and then you eat it and then like you get all these feelings when you eat it it's very very cool uh so shout out um person on on you're literally feeding the family with your project well i mean it makes a great gift get started on your cookie recipe now i mean valentine's is coming up like seeing going through the stores yeah that would be really cool okay all right next up sorry let me get the link oh crap yeah that's what i'm supposed to be doing yeah next up is uh nefertiti this has a story too that was like the scan of it was was it actually illegal or was it or was it planned we still don't know but yeah we took the nefertiti model back in 2016 and we hollowed it out and made it into a planter um so this is really nice to see someone else put an actual planter we see other folks use it like a storage or just like a thing even put a stone better than that what kind of plan is that uh i don't know that looks like mint a mint yeah that's cool that looks really cool there i wonder what kind of filament um they used so this is posted by uh isimilia electronics posted two days ago printed on a prusa i3 mk3 with some supports and a 0.25 resolution very cool nice photos it's a really fun one here good historical context yeah that is a really good photo there look at that huh i don't remember it having all those textures when we printed ours is it a remake yeah we used it on a now let's just go straight up oh it's the the um filament that they use because i think we used like hemp filament did we yeah so like wood fill but with like hemp uh-huh that's that's crazy you kind of forget you know the years like the 2016 yeah that was a while ago yeah it was a crazy good model like we had to reduce the the mesh because it was like a billion polygons or something very cool these are um in the pennies carnivorous plants by the way we thought it just fitted the aesthetic really i like the way it hang over yeah yeah that's really cool so yeah fd okay another one here this is a fun tool if you are doing lots of heat set inserts maybe it's time to make a tool this is a bit of like a drill press um project that we did a couple years ago um but this person here auto wolf on Thingiverse posted up their remix they remixed the uh the the carriage holders so that it can hold their soldering iron which is always a good thing to do to design your own kind of you have your own setup you have your own soldering iron you want to make your own um adapter for it so very very cool to see folks um creating their own thing and uh wow you get that black um uh it uses a piece of 20 20 aluminum extrusion and i'm just now seeing that you can get them in black that's really cool very cool color scheme so this was printed on a cruelty under three no supports and yeah pet g that's a good pet g um good filament that uh heat resistant and less brittle more stronger than uh the pla but that's a cool thing so check out if you are interested in making a heat set rig for doing tons and tons of heat sets and you want to be perfectly perpendicular this is a great little tool shout out to auto wolf for posting that all right we got another three more to go through so i'm gonna run through them a little bit this is a raspberry pi no this is an iphone case the iphone 12 pro max and mini flexible case posted up by eddie 33 peter designed this one uh for flexible filaments and folks are printing them out lots of folks are making this one really really nice this was printed on a prusa i3 mk3 um using uh ninja flex tpu lava that's really cool and uh 10 infill you know it's pretty good so if you're looking for a iphone case and you want to use some ninja flex it's always a good project a case slow today you know posting the links this is a raspberry pi zero stand this was a make posted up by axl ramp raffin posted this one up it is um just a simple little stand for a raspberry pi zero you can put a raspberry pi zero and a hat and some other things really nice way to kind of prop up your project if you are developing some some stuff for the pie uh one of the small stand use one of prokary's various sensors using my pie zero arming works like a charm excellent yeah just a couple screws and uh you got a little hole for wiring and stands upright at a whatever angle so that's really cool this was printed on a mono prize mini select no uh no raffin a little bit supports and some polaroid and pl a gold very cool sweet so if you are looking for a simple stand for your raspberry pi project check that out and the last one here this was a really fun project that i worked on it's no electronics but it's just the fun little storage so i probably made this when i was watching game of thrones 2016 maybe predates it but yeah uh so g newt it on think of a specific of their make of the tower storage i really like this because uh it uses screw threads so you can take off the top and put toys or whatever inside of it and it's really big so if you're a really tall printer this is a really fun um design and it has this cool brick texture so it looks just like a you know a tower um for d&d maybe you want to hold your dice or your dinosaurs or something this was printed on um any cubic predator printer no supports no rafts 0.2 layer height 0.5 infill and the description says two versions for my son and daughter that is so cool yeah i like like seeing it in rainbow back in the day we didn't have rainbow filament nice i do it's a great tall print i made it really really tall it was like as tall as gavin it was so cool yeah i like the top too and of course it has a removable top cover which makes it really really cool um yeah i like simple things that have these shapes that also double as storage we actually made it alone that's wild and you can modify if you want to change any of the threading or the thickness or whatever it was timelapse tuesday oh right yeah i really didn't warrant a guide because it's like print it okay cool oh yeah that's right it's a good print for like thicker uh nozzles like a 0.8 nozzle okay that's this week's timelapse uh this week's community makes thank you everybody for posting up your makes um one last shout out to uh prusa printers if you are looking for an alternative to thingiverse check out prusa printers um i'm seeing more folks are like commenting on our stuff so that it it boosts up their points and stuff so that they can hopefully get some free stuff when they get rewarded for their points we posted up our alfiers and we got 10 points only only 270 to go because it takes 350 i know we have 310 more points to go so we can get a spool we're working hard to earn our spool guys okay i want that beanie you want the beanie i want this filament there's the rewards they update the board now i can do the hat too the hat looks really cool oh wait no no it's the hoodie i want the hoodie yeah it's a cool hoodie yeah get 500 you can buy it we can't buy it i thought you could the the get button is uh turned off maybe it turns on when you have the points i think so that's about what's going on yeah oh that's cool you have a history of like where your points came from they did a lot of work on this this is really good this is gamifying like yeah done pretty good yeah and like it's what's working like i'm getting comments on our and people are rating our designs on prusa so get your free filament now because we toast spam i'm just kidding i didn't say that no there's actually a time limit too so you can't upload like you know 300 at one time right yeah so they have some smarts built in or something right yeah so cool all right that is uh community makes we're quick looking at the community in the discord johnny is saying that some snow molds perhaps ice candle molds with 3d printing yes we have that on the list doing that with a pewter the yeah sand is molten molten molten making some metal molds for that that is on the list yeah Aaron did it though she already did it remember yeah i think we're gonna do some a different way some 3d printing to do it okay yeah 3d printing nerd made a snowdup you know what i have that snowdup from last year i was gonna just do it with sand that's right like here in florida sand the sand mold we're a little bit away from sand i don't know no in the the volleyball uh oh that's where all the white sand is uh huh yeah that's the that's the closest kept wanting to do that but i think i threw away the mold it was like two years ago yeah and paul cutler was saying yeah the uh soldering iron heat insert definitely on his to-do list yeah just be careful with the uh the soldering iron make sure it's a good one the diameter yeah makes good diameter that and just some of some of the cheaper soldering irons will like burn out if you have it upright so just make sure that it's got a good wattage and then paul cutler is sharing oh the uh the yearly github a story in 3d yeah like that last year we 3d printed lamar's github for 2020 there's a bit of a trophy for her i've been laid out i mean zeta fruit oh i don't know what she posts that i think she posts zeta fruit laid out lamar and yeah that's what makes it super cool you can download your stl from that and 3d print it for your desk that's right i like how it's pink it's not whoa problem i broke it it's because i'm running um yanni says change of the year oh 2021 i was gonna say it doesn't work because i'm running an m1 mac and safari and nobody likes them yeah i'm like stuck in the loop folks sorry no probably safari it's safari it's always safari uh put 2022 yeah yanni says the default is 2020 put 2021 these are really great job we're probably putting them on it's safari it's safari it's always safari i have to use safari here because of reasons sorry but hey cool folks know about it i tried it all right cool i all right i think that is it for this week got a little change up in the show until coming up later tonight hosted by a very own jp he's back that's right hosting duties tentatively there will be a ask an engineer tonight at apm standard time standard eastern time so tune in for a update on aterfruit open source hardware new products yes top secrets ion mpi lots of fun a full hour every more feel something over time cool stuff coming up get their show tonight and of course we'll be on show and tell we invite you to do so you can join in by hitting up the discord chat room um five minutes before the show starts at 7 30 p.m eastern time and we'll throw in a link so folks can join in and share what they're working on hope to see you there we'll be there tonight if all goes as planned and then tomorrow continuing on with jp's workshop yep i have a thing here we go so jp is here this week and throughout so every thursday at 4 p.m eastern time i think scott has a live stream this friday normally at 2 p.m pacific time or 5 p.m eastern time lady eight has been doing stuff on the weekends from the desk of lady aida so just kind of hang out and get notifications wherever you might be and then on monday is the circuit python meeting and tuesday yesterday jp did a product pick of the week um oh boy i forgot what the product was 50 percent off it was 50 percent off whatever it was yeah i think it was a gpio expander um or no no no it was the at tiny chip thing yeah so check it out if you want more um and crazy discounts every tuesday at 4 p.m eastern time or 1 p.m pacific time only while the show is live only while the show is live yeah so we're all back to our shenanigans making cookies and all sorts of fun ear elf ears and crazy things like that so we hope you're inspired you know there's still lots of bad news and things we're all trying to push through it and we're all being affected in one way or another so we hope you can just push through and and be safe out there um yeah hopefully we can make this year better than last yeah last year was pretty good though i must say all right one quick last request from yanni he wants a layer by layer i'm making a mold a 3d 3d molds that'd be cool yeah yeah i'm going to get back into lever lairs i'm thinking though mine is going to be on how to make a a case for boards that are like the cutie pie and the zio those boards non-mountable not yeah boards have no mounting holes like i'm seeing a lot of these kind of smaller boards i want to make it to toro and how i make the snap fits for those boards a little walls for yeah because i've been doing that for at least three projects four projects now and i think i got a good recipe so yes all right cool and with that yeah thanks everybody we'll see you later tonight on uh on show and tell with that we'll see you next week but until then remember to make a great day see you tonight yay bye folks that's it
