 Hello, folks, welcome back to another 3D Hangouts. My name is Noah Aruez. I'm a designer here at Adafruit and join me every week. It's my brother Pedro. Good morning, everybody. I'm Pedro Rez, creative tech here at Adafruit, and every week we're here to share a 3D-printed projects feature electronics from Adafruit. That's right, the show we combine 3D printing and data electronics. Smash them together to make inspirational projects. We are hanging out in the Discord chat room. We wanna welcome everybody to the show. Hello, happy pre-thanksgiving. Thank you, everybody, for joining us today. We hope you are cozy and hanging out wherever you might be. So we got a fun show for you folks today. We have two projects, back-to-back community makes, and we have some fun CAD stuff. We'll share CAD stuff and some 3D printing tips. All that and more on, you guessed it, 3D Hangouts. Yes, yes, yes. Because we're in Pedro's. All right, so let's go jump back into the chat room and welcome everybody to the show. We'll start off with some folks. We got Andy Calloway, Dew Wester, Vince. Hello, folks, thank you for joining us today. If you'd wanna comment and chat while we're doing the show, you can do so by hitting up the Discord chat room. The invite code to that is adafruit.it slash discord. It's also on discord.gg slash adafruit. We are also hanging out in the YouTube chat. Good morning, aimed jester. We're in the Facebook chat and Twitch bar scope. Everywhere, the internet is working really good today. We had the lawn maintenance folks come by, which was really good luck for us, so. I think they're done. They are, so we got this whole microphone here with Luscious Audio coming in. Supposedly, we got great internet tonight. Or tonight, today, whenever. Jim Hendricks hanging out as well. Hello, good morning and happy Thanksgiving to you. Thank you for the comments. Or us. Jump in, we got free stuff. So let's go to the free page. Adafruit's got some freebies going on, as they do throughout the weeks and days. So I'll start off with the first tier for orders that are $99 or more. You're gonna get a free Promo Proto half-size breadboard. If you spend $149 or more, you get that Promo Proto Plus, a randomly selected Stem Acutee board. For orders that are $200 or more, you get the Stem Acutee board, the Promo Proto half-size, and free ground shipping for US Continental. And if you spend a whopping $299 with Adafruit, you're gonna get a free circuit playground, Blue Fruit, the Continental US shipping for UPS Ground, the Stem Acutee, and the Promo Proto. So you get all that stuff, you spend lots of money with us, which is great. Yeah, this gets added automatically to your cart, so you don't have to worry about any coats. So they're just throughout the time. With that in mind, we're gonna head over to the blog, and you'll see a featured blog post, let's zoom in. Adafruit's holiday shipping guidelines. I love that we do this every single year. We have this broken up into domestic orders and international orders with dates and times. It tells you what is your deadline. If you want to get your delivery by the 23rd of December, you're gonna have to act now. So here are some dates. I won't go through them all, but they are there in the blog as a featured blog post. So if you wanna get some gifts in before the specific date, there's a blog post for you that you take a look at. Cruisin' on over to the Jobs Board. Adafruit has a free Jobs Board for makers and employers of makers. Head on over there to find out all the latest gigs. We got some new ones from some fun places such as Micatronics, The Hack Club, Blues Wireless, Xander Creations, and Revelair Kitchens. These are all new and they're all probably pretty a fine job. So check them out. If you wanna get your resume up there with your skills, you can do so too. Again, it's free to do so. So check it out. Circuit Python meetings happen every Monday with the exception of who was holidays, but today it happened at Monday 2 p.m. It gets posted up in an archive on YouTube's playlist and all sorts of podcasting services. It's a great opportunity to tune in to hear what's going on with the latest Circuit Python. Daily Newsletters, this one. Daily Newsletters, Adafruitdaily.com. You can get a nice taste of daily stories, projects and more. Head on over to Adafruitdaily.com. You can subscribe to all the various categories, our favorite being Python on microcontrollers newsletter. Shout out to everybody for subscribing to that one. If you want to get some exposure on your Python related project, you can hit up CP at Adafruitdaily.com or just drop it on your socials and just hashtag Circuit Python and we'll try to find it. All right, that is what we got this morning. Right, yeah, I think I did everything. We've got the holiday shipping deadlines and the jobs board. So back over to over here, we got a cyber turkey. What's going on there? Shipping alert, yeah, yeah, yeah, Adafruitdaily is closed tomorrow, woohoo! We will all be feasting, feasting. Yeah, so what do we got? All right, let's go ahead and do last week's project. Last week's project, let's head on over to the learn.adafruit.com. You'll see Pedro's latest project here. Come on, there we go. Oh man, my things all messed up. All right, so this is it. All right, so with the holidays coming up, of course you want to have your desk and area nice and glowy, festive. So Lamar found this really cool lamp and she wanted it to be redone with Neopixel. So we have a 60 Neopixel ring, two 24s and a 16 Neopixel ring here. And it is creating this lovely little desk lamp. We're using Circuit Python to have all the animations going on here and all three printed, of course. We have the talk connected. So all of the rings fit right inside. And the cool thing about, the thing that I really like about this is that it's all modular. So you have all of the mullix connectors that are acting as the connections for all the rings. So they go from one ring to the next, so 60 to 24s and then up here to the little baby one up here. As you can see in this animation as it goes through each one. And all of these are, even the parts right here are snap fit. So these all come out and you can see the Neopixel rings inside here. Got these translucent filament to act as a diffuser. And of course they have the little hidden Mickey inside here and make a circle lamp without that. And inside we have a Raspberry Pi Pico driving everything, of course, with the mullix connectors as well. And this is one of the Pico cases that we've designed when it first came out. So you have expandability options. You can add, you can kind of see here on the side, you have the ability to add two more buttons. So you can have it cycle through modes or whatnot. And on the back here, you have the ability to add an on and off button and even space for a battery if you have, if you so choose to have it go portable. Also have the JST connector on there. So if you want to have your Raspberry Pi Pico go portable, you can check out the previous guide for hooking that up. So very minimal modifications. The only thing I had to edit was the lid. Just got rid of the grid that we had on there for the built-in Neopixel project there. And the USB goes right inside here. Just connect that. Micro USB. So micro USB. And then on the bottom here, this guy pops out. So you have that base. So all you're doing is modifying or just adding this as an add-on to your existing Pico case. And that just acts as a base. So it does not flop over. I like that it's modular. So you can swap out any of the parts if you want to print it in different colors or add different components. It's pretty good. I really like how all the rings are combined in one piece. So this is a one-piece thing. You don't have to attach the rings together. That's the power of printing something all in one piece. You have a nice big bed. You can do some pretty cool stellar designs. And I made the walls just thick enough so you're not wasting in infill. And the stability comes from adding the diffuser right on top, so it makes it nice and strong so it doesn't wiggle around. Yeah. And yeah, let's go ahead and jump into the learn guide for this. All right, here we go. Hit on over to learn.adv.com. Over if your page has all the parts that you'll need to build this one. Notably, the Raspberry Pi Tico out of stock, but we've sold so many of them, quite possibly thousands of them. They were in stock yesterday. Last week. Last week, so thanks for everybody picking them up. We don't get any margins on these. These just, we're giving them away because, but anyway, you want to pick up some stuff, right? We do have all of the rings in stock. I want to highlight the 60 Neopixel ring. When you add it to your car, make sure you add four. Four, please. Not one, because they come in quarters. One. So that would, that is what you will get if you order just one. No quarter, quarter is not included. And neither is the solder, solder is not included. Yeah, so you need four of these. So again, yeah, make sure that you select four or you just get one. I actually did this completely forgetting and I can receive the one. All the Neopixel rings are, you can use the drop down here and they're all listed here. So if you want any of the rings, the 12, 24, 16s are all here. But we have them here in the Learn Guide so you can pick them up. There's a button that has add all when they're all in stock. Oh yeah, yeah. And then the Pico Molox cables are becoming our favorite pairs of cables. We are ordering these. You're going to see it just now in the next project too, but we ordered so many of these. We're glad we were ordering these by the thousands. Not we in Pedro, but Adolf it as a whole because we think a lot of folks are going to be using these type of cables. So you get two that comes in pairs. So you get the socket and the plug. And they're just perfect for these smaller type of projects where you want to do Neopixels. It's got three wires. You can do data, ground and signal. Really, really good piece of wires. And the voltage, I was looking at it the other day but it was something like two amps can go through here which is good. Because if you're wondering like, well, Neopixels are hungry. Well, these cables are rated for like one amp or so. But anyway, back to the Learn Guide. We also have them in four pin and two pin. That's right. We do, we do, but we're highlighting the three pin because they're Neopixels. We also got some cables for you. These are some braided purple cables, micro USB C to USB micro B. So you can pick that up if you have yourself one of those USB C type connectors. But there you go. There's the overview page. Got some nice photos here of the new kitchen that's still in the progress. So close, so close. We're so close, we're so close folks. Let's head over to the circuit diagram. You can see here how all the data is flowing through the bottom into the following Neopixel rings. So that's how that's set up. Just three wired connections to the Pico. Really, really straightforward. These wiring diagrams, they're created with the fritzing software and Adafruit has the libraries. If you want to build your own wiring diagrams with these nice graphics and easy to use software, you can check out the GitHub's fritzing parts. All right. Installing a circuit Python on your Raspberry Pi Pico is pretty easy. We got a nice step-by-step tutorial on how you do so. You get into the bootloader mode and you drag and drop one of our UF2 files of circuit Python, latest version, and now you're ready to go. We got lots of demo code too for folks. Which speaking of, here is the demo code that we got. You can check it out. There's a total of 124 Neopixels. We're using some of the LED animations, the pulse, the rainbow, and rainbow sparkle. You can add more, take away, you can modify the brightness, modify the number of pixels, and all the little parameters like speed, sparkle, the length of the tail, that sort of stuff. Each animation is gonna have its own parameters. So definitely check out the LED animation library, learn guide if you want to modify them particular, and you can change the colors of course, right? And that's pretty much it there for the code. Really, really straightforward. So you're printing, we got some STLs and CAD source files. You can download, if you wanna modify the design, you can do so. You can download as a step file and import it into whatever CAD package, or you can just take the STL, excuse me, the STLs and modify them into something like Tinkercad. Any slice tips that you want? Everything was pretty domino, nothing that different for that, the supports just lay them flat. They should all be oriented already, so that's the only thing. You're probably gonna need a minimum bed volume of 200, or 300, what is this? Yes, yes, about 300. Okay, so just 300. Just bring it in your slicer and see if it fits, if it don't, you can split it up if you want, and then glue it. I did say the orientation, but you can clearly see in the little GIF there that you do want to have it be diagonal, that's how it was able to fit the entire part. That's a really good tip too, when you got a long, narrow thing, you can always rotate it 45 degrees and you can always get more volume across if it's thin like that. But it should be already oriented. Okay, cool. Jump it over to the assemble, we're gonna walk you through wiring up the four quarter-sized neopixels. You're gonna need a lot of solder. You can do... And a lot of patience too. The first one that I shot turned the camera. The bridging went perfect, I was happy. Then the other three were pretty much a nightmare to get to slide over, so definitely bring your patience in connecting the four pads, the three pads. Another thing that's interesting is this doesn't close because it wouldn't work that way, right? You can't close the neopix, you gotta have an opening here, so I'm just looking at how the wiring is going into the data in, and you have data out going out to the connector there. The diffuser has the separator that will keep those two parts. That's good, cool. Pushed away from each other. Right, because it could short, so that's good if you're designing something with them. Make sure you don't solder these two together because you need the out to be going into the microcontroller and the in going into the microcontroller and the out going to the rest of the neopixels. But you got lots of pads in here that you can play around with if you want to do something different. The other thing you wanna keep in mind is that you want the entire length of all the wires. They are bendable enough to where you can sort of fold them over so that they reach the next ring. Cool. Looks like when you're fitting them in, you can use the wiring to kind of make the torches a little bit tighter. So you can do that here when you're bending the wires. Oh no, you're just pushing them underneath because you don't want them against the wall because then you won't have any space for the diffuser to go on top. So that's all I'm doing there. Just folding them to the backside of the PCB and then away from the walls. Cool. These little slots on the back there allow you to have some more cable-age, so that's good. The cables can poke through there and to save on material as well. Cool, yeah, that's true. Okay, what are we doing here? We got the... Oh, cool, yeah, you just... You can orient them so that the cabling is kind of closer proximity to the next NeoPixel. Correct. So, yeah, you wanna bring your organizing skills into this one. Oh, well, we're still kind of on the... Close to talking about the bridging. Vince was saying that he's had good luck with small pieces of bare, solid wire to help the solder flow. I did do that with one of the pads. And then you can kind of see it in the photo there. It worked for one of them and then it just did not wanna stay for the other ones. They're like some header pins or something. Yeah, just header pins. Yeah. Lay them on top. Get it up, push it and solder. And then... Use some tweezers. And then they move out of the way. Oh, that's such a pain. All the time. So you can try more. For helping hands. As you can see here, it'll work. I think the other thing I tried to, that ultimately was what I should have done with all of them is just have it where you have enough solder and you leave the iron tip in the middle, raise it up. It'll create like this little point. And then just go in there and just chop that off with some flush cutters. Okay. Anybody else got tips? Drop them in the discord. But I used all the techniques on this six-string. Yeah, you got four solder, there are lots of solder joints to play around with different techniques. Cool, cool. So once you got them all hooked up and wired in, you can get a mount Pico, the USB port facing the little cutout. I did update this case so there are M2.5 screws that you can use to mount it. Otherwise, the USB cable can like pop it out. Okay, yeah. So that's ultimately what I ended up doing. The file that I include in the project file, it doesn't have the snap fit one. It is the screw on. Okay. And then the lid gets attached with some screws to the bottom of the base here, the version in the fixer ring, the 60, using the M2.5 screw. You could glue it, I guess, too, if you want. If you want a permanent. I think this is a little bit more secure. The glue? Yeah, because if it rocks back and forth, the glue can pop off. I thought you super glue. You could, maybe hot glue too. But this is a mechanical. And removable. Okay. Whoa. They're dropping their house down. That was the, anyway. What do we got here for the base? Yeah, the wires pass through the top of the opening on the lid there and it just snap fits onto the rest of the case. The circular base has fitted onto the bottom of the enclosure and that's right up to my chip. Yeah, it's got a tight fit so no need to screw it in or just press fits. Yeah, and tautness is making it nice and tight. Oh yeah, you got an extra power switch. We got these really chunky USB power switches if you want to pick one of those up. Makes it just easier to, you don't have to reach and unplug it from the wall. You can just have a power switch that's built in line with the USB cable. Bit of an extension cable too so you can throw it in any USB project. Very cool, that is the Norton guide in a nutshell. We kind of walked through it quickly but if you folks are looking to make a festive lamp with new pixel rings, check them out, we got all the rings in here. That's our way and I just retweeted somebody who just posted that they're making this suite. What is it? DNA, interactive art project. Bunch of rings. These are 16 Neopixel rings. Yeah, they're fun, very cool. So lots of uses to have this 16 Neopixel ring. This is one really good one that you can do. Vince was saying also that it'd be nice as a wall mounted display. It would be really nice on the wall for sure. We know some folks probably don't want to mess up their walls so making it stand upright on its own is cool too. I was going to say with the man folks, that's a good way to do it as well. Yeah, maybe do some cool, I don't know, stuff. Remember when you first, Pager's first iteration of it was all like straight up like that so it kind of looked like a snowman. Maybe you can make it into like a tree or some sort of stylized tree or something else. So lots of fun stuff with the rings. I saw a theming with the holidays there. Right, maybe nest them all together. So it's like do, do, do, do, do, they're all going in. Cool. Yeah, you can update the sketches inside of Fusion. Oh, we have whatever you want. We have a link to the inspiration, the original lamp, do you want to show that off? Oh yeah, yeah, yeah. Since we got a little bit of time and we'll jump into the noir. This is what it was inspired from. A touch of modern is the website and this is like a really, really tall kind of sculpture ring lamp. But you can see how they're all kind of stacked on top of each other. So by kind of moving them a little bit, I guess they give it that look. You want it a little bit more extreme where it almost looks like it's gravity defining because of the way it's angled like that. Yeah, and maybe be bold and make a bigger one with the strips. With a bunch of 16s or yeah, the strips. They got a nice base going on there too but it's a really tall one. Yeah. It was on sale for 250. Yeah. Yeah, sale ended, I don't know what it cost when it's not on sale. Yeah, I like their animations. Oh, look at that, that looks really cool in the corner there. So if you want to put it in the corner. Yeah, yeah, it'd be cool. Thanks for the inspiration, touch of modern. We love DIY. Especially since you can't even buy it. Right. Just make your own. Oh, that's neat. That's really neat animations. We can do all that stuff with the Chase animation. You can do all that with your phone if you want to use a BLD board, you know, with the Hitsubitzy. So y'all can go crazy with it. Like, it makes a great addition to your bar. Don't you have a bar? Except where they trip over the cable right there. Yeah. Any hoodle. Thanks, touch of modern and that's where we got inspired from. It was really tomorrow. It was like, hey, this looks super cool. Yeah, this looks cool. Remake. Yeah, we're gonna remake it. Remake. Remake. All right. What's up, Andy Callaway? What is going on? Oh, the lamp. Oh, the lamp. Yeah. All right. Well, that is the last week's project. Shout out, Pedro, for putting that together. Let's go ahead and take a look at this week's project just in time for Hanukkah. We got an LED menorah. I'm gonna disconnect this. Show it off over here. So I wanted to create a little kit of some 3D printed parts to make a menorah. So we have the Cutie Pie, RP2040 is inside here. I'm gonna go ahead and plug it in. And this is a collab project with Liz Clark. She put the code together. And Lamar wanted it so that you can use a push button to advance the day. So every night of Hanukkah, you can just press this button and light up the neopixel. So on the first night of Hanukkah, you got one on the far right. And then the following days that night you just push the button and you'd light up all eight because there's eight days of Hanukkah. The one in the middle here is the Shamash. And the Shamash will stay lit on all the nights of Hanukkah. We got a little 16 millimeter button here. These are all neopixel button PCBs. I have one over here that I'll show in a minute, but I'm just lighting everything up. And it's using the LED animation library for circuit Python. So you can have this nice rainbow and you can adjust the speed of the rainbow or change up the different animations you want to flicker. You can do that as well. But it's really cool that you can use the button to advance the day of Hanukkah. So let me unplug this. You can see the QT Pi over here. It's got that USB-C connector. It's got a really tight fit. So let's see if I can open it. There we go. I'm also using Molex Pico blade connector. So you can see, you can hear for the push button and then the three wire, the LED for the neopixels. So that's how this is set up. Nice snap fits. I also added some rubber feet on the bottom there so it's not moving around. Do I have our prying tool? What's it called? Oh, nice. It's not over here. It's in the printing room. Probably use a razor blade. It's less. Kind of want to open to show you guys the, you know, can you go get it from the other room? Would you please? Because I really want to show folks. So it's got a really nice tight snap fit inside. The LED case is what I'm calling it. This is where all the wiring is hidden. And the way it's set up is it's pretty similar to Pedro's neopixel ring lamp. All nine of the neopixels have these Pico blade Molex connectors. If you're ever opening something, definitely pick up one of these tools. Spudger is what they're called. We actually carry these in the Adafruit shop. The snap fits are really tight on this one because I don't want it to be kind of falling apart when you're setting it up. So I'm just kind of opening it up here. So you've got the snap fits going on. And here we go. Here is my love of the wiring. So you can see here all the, all the neopixels have these three pin Molex connectors and they all just plug into each other. So it's really easy to swap these out. And it's all nice and empty in here. Plenty of room for the wiring. And then you've got your 3D printed bulbs. So these just press fit, they're hollow so that they have better diffusion. And then there's the neopixel buttons. They just kind of reside in there and they just kind of fit in there. And then there's a little bit of a ledge here in the LED holder that stops it from being pressed all the way down. So yeah, you can see here at the bottom, all of the holders have threads on them. So they actually screw into the top cover here. And that way it's modular. And you can print them in different colors if you want. So I'm just bringing this back in. You press this down in there, a little bulb. So you can use different translucent PLA or PETG or whatever you wanna try out and just get all those snaps in there. Just wanna make sure none of the wires are kinking. But yeah, this right here also has snap fitted pieces. So it's a pretty fun snap fit, you know, design. So let me go ahead and plug it in. And we'll jump into the learn guide. But if folks have any questions and stuff, we can take a look at maybe some CAD stuff a little bit later. But let me bring up the learn guide. So here overview page, got all the parts that we're using in the project. We have just about everything in stock. So the QT Pi RP2040, it's a nice cute little board, has the STEMMA ice cream seat connector on it. So you can attach different sensors to it without having to solder anything, which is really cool. These are the NeoPixel mini button PCBs. You can get a pack of 50 of them or pick up multiples of five. These are really nice. They have these pads on the back of the mirror. I have one here. So let me show you this. This is what the NeoPixel button PCBs look like. It's just a PCB with the capacitors on it. On the bottom here is where you have your pads. I can't quite focus because I have turned it off. So here are the pads in them. They're nicely labeled. You got to be kind of careful when you're soldering this. You don't want your wires to touch. You know, you don't want the data in to touch data out, but you know, you could share ground if you want to. But this is how I have it set up. My in, my data in has a plug, mullix connector, and then the data out has the socket connector. And that's just the way I set it up. So you basically make six of these, and then you make one with a longer cable. And then the first one has like a mix of like a short cable and a long cable so that it can reach down into here. But all that's covered and documented in the Learn Guide, I just wanted to give you a look at these, these NeoPixel button PCBs. They don't really use them a lot. And I don't see a lot of folks using them either, but actually, funny story I just remembered, Liz Clark used these in her NeoPixel Christmas tree made out of wood. She used those. So how funny that we use them in the menorah. They're just really good for these style of like projects where you want to embed it, but still be able to kind of separate the pixel from, you know, you want to have your own spacing and whatnot. So it's a good type of NeoPixel if you want to do something custom like this. All right, back over to the Learn Guide. Let's see what else. The 16 millimeter button is pretty standard. If you want to use a different button, we have lots of different 16 millimeter size buttons. So if you want to do like an LED one, you can definitely do that. I just want to keep it simple. And then here are the cables. We've got our three pin Molex cables and our two pin Molex cables. You got the two pin one for the button and a USB-C cable. You're also gonna need some screws. I know everything is not fit, but I'm using screws so that you can attach the bottom cover to the stand and the stand to the base. So that's why I have screws. We have a nice M25 kit is what you want to use because that's what the holes are sized for. All right, heading over to the 3D printing page. Got some nice 3D printing going on here. Got a nice set. Look at all those parts. Kind of fun. If you're printing them out, just make sure you read the quantity in the beginning. So like you need nine flames, eight holders, two stand covers, that sort of thing. So just make sure you look at that when you're printing them out because some of them are multiples. You're gonna need a build volume. I started doing this video on most of my guides. It's like, I just tell folks, like, hey, you're gonna need to build volume at least 182 by 182. Yeah, I also have a diagonal there. So you get the most out of your bed volume. And tallness-wise, the tallest part is about 90 millimeters on the Z. When you're slicing the bulbs, I have two STLs. I got a solid version. If you wanna do like vase mode, I don't like to play around with vase modes too much. Do you like to play around with vase mode? It rarely works. Doesn't mess up your tolerances too? I can do that as well. And they also come out a little fragile. So some folks have different PLA and different, you know, whatever their slicer is, I've noticed that different slices will make the vase mode better than others. Right. So I hopped out to use the zero percent infill that works pretty good. And I can test too. I'll do one that's in vase mode and one that's in zero percent. Yeah, I mean. Which I'll show for next week, next week's time. So the hollow version is about a millimeter and a half thick, but I still have it solid. So if you wanna do, That's another thing too. You know something. With vase mode, I can't control how thick I want it to be. Right. With zero infill, you can. Yeah, these are just three perimeters. So it's all perimeter, no, you know, what would you call it, infill. So it's all perimeter. That's the style you get there. Really, really nice layer quality. Another tip is that I printed these one by one. Okay. Because that's just, the printer just. Sometimes it works better with one. They come out, not as good when you print them in multiple. So I had like four. And even four of them came out ugly. I was like, oh man, what's going on? And then you'll have the time where. Look at this, you see in there. It's super clean. They all fall off except one. Oh, that's so funny. And you know, you can play around with the brim if you want better adhesion to the bed. But I had some really good successes doing one at a time. Look at that tip there. My gosh, that's really good. This is a regular, clear, natural, clear PLA. I think it's from print and Z. They don't make that stuff anymore, but it's got a nice tight fit there. The 3D Soltech is the next best stuff. But yeah, these diffuse really nice. Like the color really shows through on these. And let me see if I can play around with the exposure. Yeah, that's kind of more of what it looks like in reals, in real person. Like they have this cool kind of, I don't know, light streak effect, would you call that? They look classy. Specular highlights. And that's what they look like over camera. They get fully blown out. But I guess if you wanted some of that, you print it with clear white. That way it has a more solid color. But right now, the way this translucent PLA has different shades of the color. But anyway, back on the learning guide. Another thing you want to do is when you're slicing the frames, you want to use a brim because it's pretty thin. So the frames in this design are this thing, these thing, and these thing here. So one, two, three frames. And they're pretty thin. Like they're about 1.5 millimeters thick or thin. So you're going to want to use a brim like I have here in the screenshot. And if folks are interested in 3D models of Adafruit boards, like the QT Pi RP2040, we've got 3D models for them here. And we've got links to the Hub repo if you want to get more of them. But yeah, I use this one to create a built-in holder for the QT Pi. It's got a nice set of features to make it grab on to the QT Pi's edges without touching any of the pins and without touching any of the components because there's components on the bottom. So I haven't been showing you that. Sorry. And real quick, I put together this little CAD animation just to show all the pieces, how they fit together. Really, really like how all the pieces snap fit. And then you have the LED holders that just screw into the top. Not a lot of fine coming up with all the parts and laying it out in Fusion. So if you want the source file, that's also available. I have the step file in the Fusion 360 file. And it's all parametric too. They got user parameters. If you want to change up the lengths or the width if you have anything, you can update that. It'd be fun to see this one scaled up really big. See, people make some big stuff with their fancy new belt printers. You can imagine printing this on the belt printer, like super huge. All right, well, quick over the circuit diagram. We got nine new pixels. These aren't really the right style of new pixels, but at least it showcases how they're going from right to left, with the fifth one being the shamash. That's the candle in the center there. And then you've got your push button going into ground in one of the digital pins. So yeah, pretty straightforward wiring diagram. All these parts are available in fritzing. So if you want to get that, we got links there. At the power it, you just want to use five volt power supply and USB computers hub or like one of those phone charger things you plug it in the wall. All right, installing circuit Python on the QDPI is super duper easy. Definitely want to update the latest version of circuit Python. I'm running the beta 7.1 right now. Super easy to do that. We've got this step-by-step tutorial on getting into the boot loader mode just dragging and dropping that UF2 file. For the code, the code is up on GitHub. Again, shout out to Liz Clark for putting this one together. Kind of short notice as well. That's using the LED animation library. So you can see here how it's set up. If you want to change up the pixel count for different projects, you can do that. Change up the brightness right here. If it's not bright enough, you can always change that. You can swap out the animation if you want to do something other than rainbow. But there you go. And here's just a quick little screenshot of what the USB drive from your circuit Python board will look like. All right, the next page is, we'll really want you to just wiring all the components. You got a button here. I got some wire lengths so that you can make sure that the connections are all reaching to the components when you're assembling. Wiring up the QDPI, you got two connectors here, the three pin and the two pin cables. Yeah, the pads on the QDPI are casillated pads. You don't really need them here, but just thought I'd mentioned that. Wiring up the NeoPixels probably going to be the most time consuming one. You really want to follow through the wire lengths on this one. And I have a nice handy photo here that shows you like all nine NeoPixels and their lengths. So you can see how the first one, I probably need to flip that because it needs to start going from the right to the left. Oops, I will horizontally flip that. I was horizontally flipped. I just noticed it like, whoops. All right, and test the circuit, right? Just connect everything together and you can power it up. The next page, the last page is the assembly. So you want to set up the top cover with the LED holders in the right spots and then starting off with the first NeoPixels starting on the far right and then working your way from right to left. This one too, I need to flip. Then the diffusers, you want to install the diffusers right after putting the NeoPixels in because once you install the framing, the wiring tends to kind of want to jump out. So it's nice to have the diffusers on first. That's why I have it in that order. And then you can work on assembling the frame with the covers. So you want to attach the bottom cover of the LED holder to the stand with some hardware nuts and two screws. And then the bottom of the stand goes into the base's top cover. There's some holes there for the wiring to pass through. Then you're going to install the QT-Pi, snap fit it into the little bottom built-in holder there in the base cover. That snap fits into the frame. You want to connect the stuff once the QT-Pi is installed and then you want to thread, you want to needle thread the three-pin Molex cable to the top cover of the LED holder because that's where the LED is going to go through. And then you just start snap fitting, snap fit, snap fit. And then right before installing the top cover to the frame, you want to make sure that your neopixel order is correct. So in this photo, it's correct. Like I have it even labeled here where it goes one, two, three and going all the way down to nine here. Remember the fifth one is the Schmosh. It's not really nine days of Hanukkah. There's eight, but you got that one in the center there. So that's a nice photo of showing like before. But it's completely modular. If things are out of place, you just flip it around and it's super easy and it's symmetric. So you can literally just flip the thing around and you don't have to take out the neopixels. You just flip the top cover. If you want the USB port, you literally just take the button to flip it and it's like super modular. It's what's the name of the game here. All right, and then once you're happy with the order of the neopixel, you just snap fit them together. The last bits are just fitting these kind of side covers for the frame or the stand rather. A lot of pieces, but yeah, those just snap fit. You'd want to print two of them because they're symmetric. There you go, man, ready to light it up. And that is the new Pixel Menorah. Which next year, we'll add a speaker. We'll make it sing and dance. IOT, you can check to see what day it is. You'll have the removable Schmosh. You can actually like, that'd be cool, right? Yeah, that's a cool idea. This was just like the starters. Like we don't have any menorahs on the learning system. That was so crazy. It's like, how do we not have any Christmas trees? We have so many Christmas trees. It's like no menorahs. It's like when we go shopping through the stores. Oh gosh, yeah. It's like one end cap or one shelf. It's like, yo. And they're not even like, oh man, I was looking on Amazon and like, a lot of the LED menorahs don't even let you advance it. Like they just turn all on. Which is what we were gonna do too, but thankfully the marz like, Liz, let's be a little bit more faithful to the... A little bit more interactive. Yeah, so people can actually use it. So yeah, and I like that it's the cutie pie because it's USB-C, it's like a Python. It's a really, really nice board for these type of projects. And you can add the sensors if you want. Oh, it's over I squared C. You can do some timing stuff. You can make it IoT if you want. You can do so many fun things with it. I would personally like, where they would do like an animation, like maybe it's like dim, so you can see that they're all on, but these are like the brightest ones, you know? Right? Yeah. Pretty cool. Just so they're not like just sitting there off. I think they should all be on, but maybe just dimmer than the ones for whatever days it's passed. Yeah, that would be cool, yeah. Or they animate, you know, like, they're like simply animating or something, you know, whatever ideas for animation-wise you can come up with. Yeah, so plenty of opportunities to modify and make it your own. Just what we really like to see. So hopefully we'll see some folks have a good time with it. And really like the modularity of it, because this is so easy and like for shipping-wise, like all the pieces, yeah, you don't have to ship it like that. It'll, you know, UPS is gonna drop-kick this. That's funny, yeah. You ship this out, but if it's already a something, like, you know, packaged. You can remake the diffusers, make them like more flame-y like, if you're into sculpting and stuff, or make your own diffuser somehow. Make them like a ninja flex, like nice and like soft. Resin cast it, so you can make some really, really fun stuff. Make stars or something. Should've made them little industry logos. So it's just in time for tomorrow? The first, no, it's actually like Declan's birthday. November 29th is the first night to Hanukkah. Wow. So I really wanted to get it right before Hanukkah. You got plenty of time then. I think so. I think so. Very, very cool. What is this? Smash? Yeah, shah, mash. Did I say it wrong? Sorry. Whoops. My Hebrew isn't my first language. Oh, that's cool. The way it's shining up the silvery PLA. Oh. It's got like a cool glow on it. I think it's the same one, though. Yeah, it's the same one. Yeah, we're using Rapunzel Silver from Filamenta, but you can use whatever from Amazon, too. Yeah, the every one. Every one has some sparkly silver. That looks pretty similar. Yeah, for like, I don't know. I think I post the Amazon links to that. If you want to pick up some of the filament for this. The transparent stuff that we use. I'll ask Lamar if I can get the shah mash. I think it's shah mash. I think that's what I heard Lou say. It's shah mash. I think I think this should probably be blue, then. We don't have any blue buttons. We have yellow buttons. But like, the order's coming later today, so I would switch it out. Yeah. All right, cool. Let's go ahead and jump into this week's community games. Every week, we 3D print some from the community, and this week, which one are we doing? The dragon? All right, let's look at the video. Yeah, the last week's is so freaking cool. Let's look at this super cool video. Holy crap. This is by Nick Gaibir. Yes, posts lots of really cool, flexible things. Definitely check out the CULT3 profile on this. This was a paid. Paid download. But a very well worth it. Oh my god. Yeah, I will have to pay for this. One print and one piece. Was it $2? $2? I mean, look at this. $2? I'm finding as many as you want. It's a thicker, sister. Yeah, you get the arms moved, the little whiskers, press fit in the place. And I'm putting it next to a Christmas tree because it looks like wreath or something. It's kind of antlers. Look at the zantlers. It's like a Christmas dragon. Yeah. Look at the detail on this guy. Oh, nice. Holy crap. Nothing special in terms of the settings. No support material. The tricks for printing. Now you just print it. It's oriented to print as is. You can see on the bottom here. It's all assembled. And you can see the hinges, how they work. They're nicely disguised with all the scales. Yeah, the scales are phenomenal. Look at the back of the tail. There's so much detail there. It really, really shows just how much detail your prints can have. And the whiskers, as you said, they are printed independently. Press in place. And then, yeah, look at the hinges. So good. So good. So here is the site. It's on Colts 3D. It's about $4. And you can print it in all sorts of, like, that's a pretty small print bed size, right? Yeah. The design is curled up. So it's as small as it can be without it hitting it. This is a great idea to print in whatever color, whatever size. You can scale it up, scale it down. And we just saw somebody with a built printer printed out a massive one. A giant and enormous roll over. I don't know if you listen to how long it is, because it's taken up by storm. Look, everybody's burning one. But daddy is asking how long of a print is the dragon. If you're asking how the length wise. Look at them all, like, flat. Where's the other thing? No, I don't know. It's 150. We have a flexible measuring tape in the other room. So it's like 300 and 70. I'd say this is probably 14 inches. It's like 370 millimeters, 13 inches. But of course, you can scale this up or trick it down. But it's pretty big enough to make a little scarf. Look at all that big one. Yeah, like the guy who printed the big one on this belt printer. Yeah, again, I'm just so impressed with the way that the scaling and the detail is on it. The arms moving, the antlers. Very festive. Had time. I would have painted the antlers and the eyes. Check it out. How much is it? Yeah, $396. It's an excellent price for such a beautifully designed model. Yeah, very, very cool. We love dragons here. We bold always take the opportunity to tie a lapse of dragon, especially something that is this beautiful. Best dragon we've printed by far. What's that? Best dragon we've printed by far. Oh my god, yeah. Look at this. Look at that. The sign here is. The yarn in the overhead. I'm not. Sorry. That's marising. Right. Move his head all with the antlers. Yes. Everything's fine. All right, well, that's one of the. We got one more. Oh, another literally right there. 3D also really cool one by 3D world. 3DD printing world? Yes. I think it's John. His name is John. John. Yes, we've printed John's stuff before. Famous now for all of his collapsible swords. He is the master of collapsible swords. For sure, especially with these master swords. So freaking cool. He has one where it's dual extruded. So you can have one with the colors already on there. So massive that is zoom out of the camera. That's crazy. But this is a very well designed, retractable, collapsible blade, whatever you want to call it. Look at this thing. It's so cool. It's hidden inside the handle folks. And it's removable as well. So here's the massive handle. Perfect. I can get this in the shot. Comes out very nice and smooth. You can print this as individual blades or he has the model where you can print it all in one. Definitely recommend doing each individually. That comes out the best, I think. That's the tip here, you should. I'm standing back folks. Get it in the shot as far as possible. Ouch. And very creative in terms of the way that the blade can easily come in and out of the overhead. You can see that the pummel screws it in and out. So there's a thread in here. And you can see all of the blades. And they're just slightly tapered. That's the way they work. They're slightly tapered so they catch each other. It's almost not even noticeable. But yeah, printing them separately and playing around with the different thicknesses of the layer. Yeah, so he has them. So you can print it in vase mode, but I just did 0% infill that came out the strongest with three walls that I used. They are up on fangs.com for you to download. Shout out. Now we've generally paid for this. Yeah, we totally paid for this. This is a new site. Just now kind of noticing fangs. So check them out. I think it's kind of cool. I don't have an account or anything yet. I don't plan to upload to there. But I don't know, maybe we'll change your mind. But very cool, you can kind of spin. Yeah, and we were already posting in like three different places. But yeah, check out John's profiles all over the place. He's got some really stellar designs. Very, very nice stuff. Best collapsible sword yet. Yeah. And definitely check out the dual extruded one, or I was just gonna paint this one. Here it is. There's a little photo of it. And yeah, I know. I see the master sword in both purple and blue. The purple is just what I had more of in the spool. So, didn't purple? Oh, wow, he has a three color one too. Yeah, very cool. You do have to be specific with your designs when you're making something in three colors. Very cool. He's got a really great Instagram. I don't see it linked here though. Yeah, yeah, he like builds printers. Does it all? Yeah, he has his own custom rep-wrap IDEX printer. Very, very cool, John. Thank you so much for sharing. Excellent. Great design. I bet you're gonna make a lot of kids' birthdays or Christmases or whatever have you giving day very happy because this is such an awesome gift. Yeah, my kid is counting down the days until when we're done with the show. Yeah, because every time we print something, he wants to play with it. It's like, you can't touch it until we're done with the show and once we're done taking photos. So, I'm sure this will be destroyed by the end of the day. Maybe. Yeah. George Gimbal on the YouTube is asking, is there a 16 millimeter button that has a NeoPixel? No, not yet. We do have a push button with a NeoPixel in it, but it's like 30 millimeters. This is a big one. It's like this tall too. Oh my God, yeah. It comes with its own cable harness and everything, so you're gonna have to fashion your own. I have a tutorial on how to add one to one of the 30 millimeter arcade buttons. Don't wanna do that. Yeah, all right. The way you wanna add the LED to the buttons. Keep trying to add it. Get this out of way from the microphone. Yeah, I know it's gotta be loud. I carefree with this mic. Like, so far it's been, period has been well. No, I'm trying to be for people's ears. Oh. Okay. The courteous of that. Right. All right, so I think that's it for the show. Yeah, folks, thank you so much for joining us tonight. We hope to see you on asking. Wait, we wanna see you on the show and tell. So, we invite you to come on. Everybody's welcome. It starts around 7.30, but if you wanna join in, just a couple minutes early, PT, Mr. Ladyata will post up a link to the StreamYard at that time. In the Discord chat room. So, make sure you are in the Discord chat room if you wanna share some of your projects. We hope to see you there. We'll be there tonight, I think, if everything goes okay. Yeah. This is this week hosted by Lamar and Phil. Yeah, they're back at it. And that's show and tell. And then, oh, Ask an Engineer is also right after, at 8 p.m. Eastern time. Yes. We've got the new products, new keyboard stuff. First stuff coming out, yes. I gotta get ready for some more keyboards. Yeah. So, definitely keep that. Infood.com slash new page open. I just closed mine, dang it. Sorry. We have to order stuff just like the rest of you. Yeah. Oh, it looks like we have a new air gun soldering. Oh, my. New workstation. What? With four nozzles. Oh, the ESPS three boxes in stock. Yeah, but hey, make sure you tune in. You're gonna get a 10% discount. Maybe, maybe another one, maybe more. But we've got some more sales and things going on. So just, you know, pay attention to the socials and stuff. Don't win around though, because everything will probably go out of stock like it does every single year. So, jump on that. GIF, do not miss out. Okay, I think that's it. I think he's off. Everybody's off. We're gonna be off next week. We're off next week. My birthday is right on Wednesday. Page is right on Wednesday. Yeah, yeah, so happy birthday, Pedro. Everybody gets your birthdays in. Your birthdays. Well, then it'll be next week. If you wanna follow along, I'll post all the stuff that we're doing. It's just apocot. We'll be around there. If anybody else is around, come say hi. We have run into a couple of you, if you, at the parks in the past. Right, even, yeah, anyway. Just coming out of the bathroom. Hey, it's Adafruit. Oh, hey, let me wash my hands. Yeah, yeah. One time we had, it's time for stories. The scavenger hunt. Yeah, the scavenger hunt. So we had the scavenger hunt. It was so warm. It was so fun. The kiddo really had so much fun. Had a hidden little Raspberry Pi, dual extruded logos around. Well, we wanna wish everybody a festive, festivus for the rest of us. Thank you everybody for tuning in. Good luck with all your maker endeavors. We hope everybody's enjoying the time off. And thinking about some projects, getting creative and... There's a lot of cool ones cooking up. Yeah, see you guys in two weeks and later tonight. Thanks, folks. Remember to make a great day. Great day, bye, everybody.
