 Hello and welcome back to another 3d hangouts. My name is no ever weeks I'm a designer here at Adafruit joining me every week is some brother Pedro. Hello. Good morning everybody I'm Pedro has creative tech here at Adafruit and every week We're here to share 3d print the projects feature electronics from Adafruit. That's right This is the show we combine 3d printing and DIY electronics to make inspirational projects Hello, everybody hanging out in the discord chat room if you'd like to join us during the show You can stop by the Adafruit discord server and say hello drop some memes Gifts gifs all of the things are fun The link for that is discord.gg slash Adafruit Let me get my banner banner. There it is We are Hanging out there in the discord chat room welcome to episode 421 or is it 22? I forget It is November 8th 2023 and We're hanging out. Do you know what episode number it is? I don't remember. I don't know Yeah, let me Check real quick here We have a boy Why is our playlist truncated? Like there it is add new things and make it more complicated. I think it's 21 if I'm not mistaken Did I add last week's to the playlist? Let me see here We are struggling a bit. We're a little late We're catching up on stuff, but deal with us Pedro you want to shout out people in the discord chat room? Yes Shout out everybody hanging out this morning with us. We got Vince We've got squid that JPEG cup of coffee Rozen to Wester all hanging out of the discord. We're also hanging out in the youtube chat on twitch Which yep did load on Instagram periscope cool, and All right, I added last week's show to the playlist. So we have 421 Videos so we are indeed 421 and good morning Nico over at the youtube chat Get a couple of festive projects coming up.

So hey you have one too. How about that? Yeah, so this is a fun project that I started a couple weeks ago It is eight LED noodles that are strung together and they're powered by a QT pie RP 2040 With the assistance of an LED driver, so it's plugged over ice I squared C You can control it using PWM and circuit pythons. You can do some really nice Fading of the brightness with a gamma correction. It's pretty cool Pedro you have like all of the LED noodle colors Blue yellow This one's warm white. I believe a warm white. I miss yellow I think I've had them all but yeah, you can see the difference between like say the red and the pink You can clearly see the different gamma on that. I Went for a more traditional Combination of just two colors the outer spokes are green and the inner spokes are red The my camera is a little bit hard to kind of distinguish between the colors because it's light But they look really vivid in real life So the tree itself is a one-piece Kind of design that you would print in a translucent material or a clear resin if you're doing a resin print And then I have this clever a tree topper that's designed one piece here and then Two halves that are glued together to form and they'll go as the star. It's a little bit of a Has some depth to it. It's not completely flat Actually didn't glue mine in. Oh yours just Well, I glued mine and You can do that. I printed mine at like a point one. Oh They're height so you can get a little bit more detail out of it So if you're printing it in resin, you're gonna get really good detail Oh, yeah, but everything prints with no support material the voltage wires are actually hidden behind this Heat shrink tubing Pedro used a straw which works out really well, too It's just a clever way to keep your wires bundled together But you kind of have to route the wires down into the bottom here in order to to properly power it Because the LED noodle is you know a cathode and anode on each end and how would you bring them together? Well, you you get them at the tip You can see all the wires kind of Coming down into itself and then this is just hollow and Then I'm using a little bit of mounting tack to kind of keep it in place because doesn't it press fits But it doesn't stay in place So a little bit of mounting tack goes a long way and then the base is two pieces You have actually three pieces you have a cover here that has a snowflake that's engraved into it Which looks really clever. It has these four mounting tabs that get secured to this base And the base itself has these counter sunk screws that attach to the cover and to the LED tree and then you have a separate mount for the cutie pie and the LED driver, which is the AW 9523 That's the LED driver chip, which is really nice. You can do up to 16 LEDs Some of the LEDs you can do without resistors, but because these have a pretty they these are pretty current hungry LEDs We we are using resistors, but for smaller projects. You don't have to use a resistor, but we'll go over that And yeah, I like that it's modular So if you have something else like an Arduino pro micro or something else or a Joe seed studio thing you can swap that out here But we're using of course the cutie pie with the RP 2040 chip because it has a built-in stem a QT port Which allows you to just connect it to the LED driver board which makes assembly a lot easier So that's pretty much the whole model electronics pretty straightforward It can be a little it's pretty challenging. Yeah, because I know I put it as an advanced in the guide because It's like almost building like a ship in a bottle because you do have to like use tweezers and be very Very finesse to get these wires to all fit through Your piece of heat shrink tubing and then Pedro you did something clever with the cover You actually created a slit so that you can just feed the wire instead of feeding the wires through this one hole in the center Of the snowflake you can just pass the wires through the slit which makes it a lot easier So I have those both as an option Same thing with the the straw too If you don't pass it through while you're still threading everything through yeah cut the entire this is like a chick-fil-a Straw just cut it vertically all the way through and it should have enough It'll like close up on itself. So yeah the heat shrink I still have a heat shrink in there though just to have it bundled up You can see the way that it pops out of there. It keeps the string nice and like bundled right at the top here So you can see that the white Shrink wrap is still there. I just have the straw right over top of it. Cool very nice. Yeah, it's about 11 inches tall So it's desktop-sized It's meant to be powered through the wall. So I have this, you know USB-C cable that goes to my wall adapter But you could power it off a battery. We were doing that for some of the shots where it's rotating But it's only remixable the the STL and the step file and the fusion 360 models are all available And you can use all sorts of fun filaments for the top I'm using a copper and then that tri-color filament from Xyro that has this really cool Gradient this this topper works really well for that and then you can use whatever for the base But having said that I used PCB way to 3d print me a super nice resin version It was a little late, but this is printed in clear resin using their 3d printing service from PCB way It came in a little deformed So it was like kind of squished But I was able to flex it and then use the topper the cover for the base. I was able to Squeeze it into place and then get my screws in between the tabs. I did have to tap these Threads with my screw tap, but it worked out. Well, I Was only I ran out of time, but I was able to get one LED noodle fitted in there and because it's super smooth Yeah, it It installs beautifully like it's so nice if it's perfectly like a glove it stays in place I can still take it out. No need to add glue to it It looks beautiful. I can't wait to I think over the weekend. I'll like swapping over. Yeah Actually, it's very nice. It isn't cheap Right it costs $30 to get this but plus $30 shipping you're looking at $60 But if you want something one-of-a-kind, you know model And it's fairly big, you know, it's this big if you have like a resin printer That's that can print it big do it on yourself, but if you don't and you want to spend a little bit of money You can get it printed from PCB way. I think they're the only ones that do a clear Varnish finish on their resin parts and it is flexible. So it might come in a little Distorted deformed, but it will flex back into shape once you mount it to this to this cover Yeah, we were chatting about the material properties of that before the show you were saying it's not grippy So it's not like a ninja flex 85a. No, it's not good at all. It's very slick very slippery But yeah, that's a nice part for it. You're saying they spray a varnish on there to get that. Yeah, right Yeah, they do it has no smell and it's not tacky. So that's very nicely cured So they cure it and post-process it for you, but it's very very clear. You've seen us print other models like this d20 Very clear and some of the place models. Yeah, but it's not hard that it's like Like like mope malleable. It is valuable. Yeah, the thinner it is the more malleable it is So we we three printed our snap fit cases as a test and that seems to work out so you can do snap fit geometry The exact same geometry for like an FDM print Yeah, I don't know if it had supports. It probably did but I don't see any You know blemishes or anything like that in the print. It just looks super smooth and clear So if you want to do resin you can do resin Very nice, and that is my review of PCB way came into farmed, but it wasn't too bad of an issue. No, it actually Probably it's one of the material properties for it. I'm sure I think they give you like a list Like if it's good for a temperature like high temperature or something like that and yeah, you can do some Italy durability Yeah, this one here is like a high temperature That's that black resin. It's a different type of resin. It's like high resistant to High temperatures and a little bit more durable. So we had our lightsaber held printed in that material But yeah There you go That is our quick update Okay Over on learn.eatafruit.com is the learn guide was published yesterday Overview covers two product guides We have a uber guide on noodles if you want to learn more about noodles or some more demo code You can check that out or if you want more information on the LED driver. You can check that out Everything is in stock you can choose your color of LED noodle we have a bunch of them and They're the 300 millimeter long version If you click on one you can see that we have all the different colors blue yellow pink Red they're all about the same price Just be careful that Is the voltage who wants? Wants to be more power hungry and just by looking at it with the resistors on there You can see it's like the green the blue And the orange it's like the pink Probably put like a 100 ohm resistor on it to get So it's not you know so dim where you can see all the individual little lights Yeah, but yeah, the blue one You can see the green there that it's all Yeah, the blue one is Yeah So you can scroll down to it tells you that the the specs for the data sheet for each color to yeah, yep So one thing I always thought was funny as we'll get to it So these are the parts you'll definitely want a stem a QT cable, right? I guess we're at a stock for the shorter ones Maybe you can get those from other places The QT pi between 40s in stock and of course the led drivers in stock. You do want to have some resistors So when I originally did the first prototype I didn't use any resistors and they power on But they draw so much current that the circuit Python drive doesn't mount This is a very strange thing but if you look at the product data or the The product learn guide about the led driver you'll see that in some cases where you do draw too much current You'll use a resistor even though you don't need a resistor on some smaller leds So I think up to four leds. You don't need a resistor, but once you max out the current You're gonna need some resistors. So that's just the way it is And then a couple screws here listed, but that's pretty much the main circuit Well as speaking of the circuit over on the circuit diagram, you can see here that I have my leds wired up But only four of them have resistors Pedro you put resistors on all of them, which is a smart way to go. I Didn't know yeah, that's fine I was testing like all sorts of different combinations of resistors and it turns out just Four of them was just enough to not like, you know draw too much current So depending on your colors, you'll want to use resistors depending on which color you have But for me in my setup where I had the four reds and the four greens the red the green ones Tntu have worked best with the resistors But yeah, otherwise, it's pretty straightforward. You'll want to make sure that your ground and Voltage wires are matching in pairs Because they're not then the driver just won't power them properly So you just want to make sure that they're you know in the right corresponding matching pairs of pins But it's pretty easy to read the pins. Yeah, otherwise it won't light up sequentially how you want it exactly Yeah, yeah, and I we came up with a clever solution to to kind of test The the wires once they're wired up. We'll see here in the in the assembly in a minute But yeah, this is all put together with the the open-source fritzing software Adafruit has a parts library. So you can always Download the parts or the library as a whole and create your own wiring diagrams But yeah, we still use fritzing and probably always well All right over to the CAD files you can get the source files It's the step file the fusion 360 file and this STL's Handful of parts The nice photo there your build volume you'll want a 3d printer with a you know minimum build volume of 112 By 230 so that's kind of tall. I printed it on a cruelty Ender V2 and or 3v2 Pedro use this your 10 s pro. I believe Definitely enough space there. Yeah, and then that's just you know helps you See before you download the files if it's gonna fit your printer If not, of course, you could use a third-party like PCB way or Some of the other ones you do want to use a translucent filament if you're doing FDM 3d printer. We use just your regular clear filament. I use clear filament. Did you use clear filament or white filament? Yeah, it's the clear from hatchbox that came out really good. Cool. That's a translucent and sturdy like strong nice I use clear filament from Matterhackers I believe and You could try white, but it's gonna be a little bit more washed out I think mm-hmm the clear tends to work well no support material on this because just the geometry works out where you don't Maybe you want a brim maybe not did you use a brim? Yes, I did I did okay, so sometimes a good idea. I didn't I was lucky my bed still fresh So it's still got a lot of stick to it so that worked out well and Then if you want some 3d models of like the LED driver the QDPI you can go to our repo on github and download those models or fetch them out of the The fusion 360 model if you want, but we have these in different file formats, too And that is the cat parts Over on the circuit python page just walks you through installing the latest version circuit python on your QDPI board So you just walk through that and then the code the code is basically the demo code that I cribbed from Phil B. Phil Burgess is uber noodle guide He he already had like it set up for like two LED noodles, so I just added more pins And that was it. I just added more pins, but this takes care of Doing really smooth Fading using gamma correction is using like a sine wave to Using math ramp that yeah ramp it up and make a really nice smoothing thing if you look at like the the demo code for the LED Driver, I think it's not as smooth So Phil B. Did a good job here where he like added a little bit of math and gamma correction to make it really nice and smooth So you can get some really nice animations With this demo code, but yeah, it's pretty much from Phil B. I just added more pins. That was it But we do have an LED driver library. That's the Adafruit AW 9523 library We'll set up an Arduino library for it if you want to use that But you can use the project bundle, I think there's just two libraries that get added to your circuit pi drive But yeah, it's pretty straightforward Onto the wiring you'll want some short wires and some long wires. I have the what the lengths of the wires for each of the ground and the voltage And you just want to solder them up. I really like these Omni fixo Helping hands. They're the best in my opinion. They're magnetic. So I'm using them here So you want to create your sets of LED noodles depending on the colors, you know, just want to make sure that you That you have some sort of way to differentiate between the voltage and the ground wires So I'm using white wires for the ground and red wires for the voltage wires The LED noodles have these little dots on them on one of the pins and that lets you know That's the anode which is the voltage like the the positive pin and Then the one without the notch is the ground And so on the noodles is pretty straightforward. They literally press fit into the channels of the spokes on the LED tree part They can come off but because they're silicone based Skin like they they grip on pretty well So you just want to make sure that they're like kind of evenly spaced. There is a little bit extra space on the top and bottom Just because that's just the way it worked out with the model like I couldn't get it exactly precise No, you need it actually for the soldering part there for the wire way connects You're gonna need that extra bit there So try to when you're putting like dry fitting it on to see where you need it to go Make sure you have extra the space is even on the bottom and the top so that the wires Yeah, the space to put them on there and then don't twist them. They are not us. They're not a like a Circle they're more like a It's the shape called I know it's in the uber guide Yeah, it's like oblong so it's like a little stretched So I get like the thinner Section to press it in there because then it'll hold The wider part will like press fit against the walls to sort of press fit it in yeah It's we it squishes in because of the silicon. Yeah With friction and as you're like press fitting it into the the little the channels make sure not to twist the Noodle to so make sure that it's like all in one like unison. So it's all not twisting around as you're Twisting it around. Yeah, it could break I guess in that sense because I haven't been able to break it but I Was saying I was thinking not breaking but more long lines of the way that it looks when it's gonna light up You don't want that because you do see like sort of a dark spot like on one of the sides So what I'm doing is like hiding it, you know, so it's against the wall. So it's not visible So that's one thing to look out for to when it lights up You will notice if you're twisting at your noodle around. So just try to have it all all the LEDs facing One side direction. Yeah, one direction. Yeah. Yeah, so yeah, totally So I just thought of this for the wiring you should have put header the header The headers that it comes with and then just use female jumper wires Connected to one. So if you get it wrong oops, let me just pop it out and yeah, you could do that or Yeah, probably that'd be better idea than like using because then it's like non-destructors. Yeah, mm-hmm. Yeah Those are good. Of course that's right always when you've done building a thing Yeah, I'm sure folks will come up with their own solutions too, but I recommend using the silicone wire We have spools of them in different colors. They're here in the product list link And we have all the different colors of heat shrink tubing, but you could use a straw or some sort of crafty Thing I ended up using two Heat shrink to beings because they weren't long enough. Yeah So, yeah You want to get the wires in there though and they're all pretend so that's good to have everything pretend before you start installing it So and then feeding it through the center can be a little bit tricky, but just kind of squeeze it through I ended up like budding up the heat shrink tubing just to the tip of the wire so I can like Avoid fraying the wires, you know when you're inserting it. It's like threading a needle essentially So well once you got that going on you can slowly pull the wire so that it's taught at the tip here And here's what the tip looks like And then from there you can get you can either choose to use The the cover that has a slit or the cover that does not have a slit and get them threaded through the hole depending on how you want to do it and Then from there You want to you can you can either have the Let me assume in you can either have the the top cover or bottom cover fitted through The inside of the tree or have it on the outside of the tree I have it on the inside of the tree, but I had to flex it a little bit to get those Yeah, I couldn't I couldn't get it in. Yeah, I noticed you didn't need to yeah, I tried but yeah You know, yeah, like with this one. I think yeah with this one. I have it on the outside So it works either way. It really does. It really doesn't matter So you can choose how you want to do it and then here's how we came up with like testing because once you have the wires all Threaded through the heat shrink to be threaded through the top thread it through the hole in the center of the bottom cover How do you know what wires what because they're all the same color? Well, I'm using a CR 2032 coin cell battery to test out the pairs of wires So I'm just like testing out the wires making sure what lights up and then that way you can figure out what kind of Order do I want my noodles to fade in because if you're doing it? Through the code you can change it, of course, but if you want to be all kind of sequential going around in a circle you want to Create your order by figuring out what wire goes where So you can use a coin cell battery to test out your matching pairs of wires. So that's what we did here Yeah, I did the hard way Looping hard way Doing each one one at a time Because that involves taking it off the helping hands moving it over like So you're doing this back and forth of remounting unmounting remounting unmounting because you're soldering each one like getting it through The ground and the the power soldering it up having the AW9 held on on mounting it moving it over moving your tree over Yeah I didn't want to do that. I was like I want to make sure that it's there's no way because there's no other wire here You know, I'm doing it wire by wire Yeah, but then you have to yeah, it's hard. Oh, yeah, it definitely is It's easier when you're not filming because I didn't have to worry about that. Right. Yeah Right, I'm sure people come up with their own method, but I found that to be okay Yeah, I think the other way too is just having like little strips I mean, we used to do this when first started having like little pieces of the tape and then taping it Oh labeling them labeling it that way. Yeah, that's just as time-consuming Yeah, which which one you want to do? I think it's all the same It is it's all time-consuming and that's just the nature of this and even with that I mean like, okay, I know this is grown. I know this is positive. I had a Frickin flip the wrong way So how to go back in there well, it's out of the ground put it in the you know Just basically just swap them out for each end. Oh sure a quick story when I originally did it I actually had all of the voltage wires going to one pin. Oh So they wouldn't animate. They would just stay on. Mm-hmm. So I learned quickly that like, oh, yeah The LED driver needs to have individual voltage pins. That's why there's so many voltage pins You know, I had the same idea but with the ground I was like, why don't I why don't we just hook it all up to one around? Oh, yeah. Oh, because that's Yeah, figuring out which one to go next. Right. It'll just yeah, the driver wants individual pins. So That's why you're doing it. But other way you have a whole set of pins here. Um, I have the the resistors um on the ground, but you know resistors are They're not very polarity driven like Polaris if I think you go on either way, I just like having them a little bit on I remember doing it on power going Is this correct? I don't know Oh really? No, it doesn't matter. That's what I thought one of the problems was when it was Yeah, 220 ohm is kind of the the standard Roll of thumb for your led. So that's what we're using here. You can get a pack of them um, I just trim the wires or trim the the leads of the resistor short and um Yeah, just uh, I guess you could add heat shrink tubing here if you were afraid that you'll short them out But I didn't did you have to no, there's enough spacing between the Resistors you can see there. Yeah, unless you bend them right at the tip. They're not gonna, right, but yeah Me too. Yeah, and you kind of create a right angle I did yeah Yeah, so and then you could always bend them a little bit just be careful Oh, yeah, they're yeah bent at a what is that 90 degree or whatever? Yeah But uh, yeah, once you get them soldered in It's easy to plug in the cutie pie. That's so nice. I don't have to solder four extra There that's a nice break and then from here the pie is now Non-destructive, man. This is very nice Swap out the cutie pie if you wanted this be a wi-fi you can add in the cutie pie Or the esp pico and then you can have a wi-fi led tree if you want We have all sorts of cutie pie bffs if you want it to go off a battery you can do that Or sound reactive or sound reactive. Yeah, I thought that's what the code you grabbed the one How lis made it with the with the midi controller where she had it plugged in To the thing that that that's what the code was Nope Just standard pretty basic, but from here you definitely want to test out Um You're wiring before you start installing the mounting the mounting the pcb mal and the base and all that So this is a good stopping point to test out your noodles Um, I do have a bracket here. Um, it the the cutie pie just press fits in Um clips into the little holder there and then we have some standoffs um and some m25 screws for securing the uh The led driver because that one does have four mounting holes or m25 size holes so you just pass them through and then um The um you're basically self tap them with the screws um to the uh onto the standoffs It's pretty thin. It's pretty flexible. So it should print pretty pretty easily And then there's two extra tabs On the pcb mount to attach it to the two holes the corresponding holes on the base here Um, so you get those in you use some hex nuts To secure it in place Although I didn't need hex nuts because like the tolerances were tight. So it just As you can see in the photo, I actually don't have hex nuts But if it's loose on your printer, you know, you'll want to add those hex nuts so it doesn't fall out um, but from there you uh, you just want to be careful with the wires and make sure you're not kinking them And that the led noodles stay in place inside the channels when you're fitting when you're when you're joining the base to the tree Um, so you just line up those mounting tabs and then you can insert those m3 screws um Through the bottom of the base and they kind of poke out through the top of the cover Or the top of the led tree and then use some hex nuts here here. You can see i'm using um My wire cutters as a way to get in between the spokes to hold the uh You know to get the the hex nuts like secure it on tightly Um, when you use a drill, um, it'll tighten it without really hold it. Yeah, because it spins so fast that it Tightens it for you Yeah, I thought about doing it in the reverse where I'd have the screw come up from the top But then you can't get it unless you have like a right angled Yeah thing. Oh, what about the long ones I sent you the long bits. That's why I got them actually for It's still a very tight spot. I think the spoke just gets in the way Uh, so Do you have a drill the the little Let me just send you one of the little drill. No, I have one of these things and He's a right angled socket. Oh, no. I meant like just drill Oh, like I stopped using the that little pen when we used to sell. Yeah freaking garbage, man You can't tap nothing with that. Yeah, you got that The bigger drill. Yeah. Yeah, I'll get one. Maybe christmas Uh from there though, I got these rubber feet because if you don't have them Those screws stick out a little bit So rubber feet are great and they give you grip. I still have to add mine. I forgot because otherwise it's going to lock Just a little bit scratch your table Yeah screws on there Yep, the last bit is to uh Attach the topper and the Adafruit star to the little hole Um, they should have a nice friction fit. If not, you could add some glue Uh deeper tool to the Open up the hole a little bit if you need. Yeah, you can do that. I think I used the my little sandy filing tool to open it up a little bit After that, you know, just plug it in. You got a nice hole for the usb Cable to stick through you want to use a 5 volt 1 amp power supply or your computer's laptop or usb battery And that's it. That's pretty much it. Um, the hardest part is like, you know, just firing it. Yeah, wiring it up And uh Getting it even if it's randomized, I think it's still going to give you a good. Oh, yeah, yeah in fact like I I will never see this in a store for purchase because of the assembly for this. Yeah, it's fucking hectic There's no way You could sell this for 50 bucks or you know, whatever retail you know Because the assembly for this alone is like, you know Yeah, no way. So yeah, and and it was modeled for the led noodle like the length of the noodle like it's modeled for it So you could scale it up. But like, what would you use? I guess like a neopixel strip or something? But then you're looking at like But yeah, it's pretty neat. I want I've been wanting to do a three-dimensional led project With the holiday here It just made sense to make it an led tree. So it's perfect for the desk. It is uh, so colorful It's the the design of it. It's like yay Yeah, it was very it was very tricky to infusion to come up with like a way to create a channel Because I can maybe I spokey thing But it took it took a lot of trial and error infusion to do a layer by layer on the construction. Yeah, I'm thinking about it Yeah, it's a combination of like using the coil And then sweep and then the pipe tool like I rarely use But the pipe tool works out really well for creating that channel Yeah, so That is this week's project. Let's check it out It is live Should uh, send the print to jp so we can use it on his lego town build Like it would fit so well with all the light up decoration stuff that's going on right now Yeah, for sure Yay, led noodles So pick up your led noodles or your led driver With our kubanko led tree You get 10% off your festive Parts is a good idea vince is saying that he wants to do some cnc Uh cnc some channels and wood for them. Oh, wow. That would be cool. This is a good idea Yeah Yeah, you want to use a small they're about two millimeters Um in diameter the noodles. Mm-hmm Yeah, stay around there So what is two millimeters to inches in the attempt of not being too repetitive? Too repetitive. I wanted to do one with the noodles where it was the um The mighty pups the new movie for The mighty pups while it came up. Yeah, and it's basically avengers with the pups Okay, like these uh, like their suits look just like the avengers, but it the it looks like it's led noodles in the freaking You know, it's just a cartoon, but it looks like the way that they're doing the The lighting for the costume. I was like, oh, this would be awesome for a harness for our dog Hmm. Oh, that's a good on discord Um, getting the length would be a challenge from Vince. Yes, that was a challenge for me Like I couldn't get it precise. So a little bit of slack is okay. I think And then DJ Devin is saying, um, it's thinking the same thing with aquarium tubing That could be cool. Yeah getting them in though like, um Getting them to stay in place is I guess the thing like how would you do that? But uh, good idea. Yeah, yeah, I was thinking too like what could I print or what could I Take from off the shelf to uh to keep the noodle in shape um, there is the um the solid core wire like a brass wire that you could shape and form and then you can kind of Use nylon filament or something fishing string to kind of tie it to that so you can do that I think the easiest one is the one that we ran out of time for and man, I was sick over the weekend Otherwise, this is exactly what I was going to do with uh, what um is mentioned here by Oh, where'd it go? Looks like it was just deleted somebody in the discord just said that can we 3d print? I thought it was squid the comments gone now if we could just 3d print the tube And yeah, that's what I was going to do but man I was under the weather Oh, and you were already like filming and yeah the learn guide at a certain point. It's like it's cut off man We can't do anything more. I thought about creating um It would be like integrating a tube into the cover Would be interesting because then you can create this kind of cool shapes, too But I say separate with a with a Spirals so it's hidden, you know, I mean so you don't see like the slit on there Yeah, you could 3d print the tube for sure. Yeah, you could totally do the different one Yeah, then it would be the perfect link and everything. Yeah the straws These Chick-fil-A straws perfectly perfect color perfect diameter And then the characteristics of the straw itself like I'm saying it like closes in on itself So it hides where the um where you you know, thread it through or not even thread and just push it through Yeah, yeah all sorts of Different ways to do it fastest way. I didn't think it was gonna work I thought it was gonna look lame and it was the last straw To literally the last straw the last straw. I think the other one was like a mcdonald's one I was like this is gonna look like a freaking straw Because it has the yellow and the red in there This is a this is going DJ Devon's like you could with a slip ring. You could have a rotating Christmas tree. Yes I actually was thinking to do that, but I was like man that is so involved a little bit too Over the top like I really thought about doing that and I was about to get the smallest Uh slip ring. We do have a pretty small slip ring, but it's just a lot of extra work I did think about like having it spinning slowly Yeah, that was I was like I I need to come up with like a minimal minimum viable project And having it just being static Was it was enough for me? Um, but yeah, I give that a give that a try man. That sounds really cool. I did think about it Um, I've been wanting to use a slip ring to do something like that Had something spinning. It's going to be the r2d2, man Yeah, probably r2d2. There's no way around it for that one. Yeah, I'm gonna get that But yeah, we do have slip rings Yes, that's definitely a mechanical gear project the r2d2 Yeah, all right. Well, we yeah again Apologies, this is not a simple one Like I did this like right when at the peak when I was sick at one in the morning soldering this stuff I'm like, oh my god This is a cool idea from Yanni So using nails on a on a using nails on a piece of wood To kind of create this That is a good idea. Yeah, so imagine having your noodles kind of go through Obviously, you don't have the dexterity like a like like yarn Or or thread. Yeah, you think there's the idea is there's a radius that you can bend it I think philby has it in the uber guide the right that you're able to bend it at. Yep. Yep about a millimeter. I think It's like bending metal like you have this like allowance of uh of clearance and the bend radius Yep I Cool pass that on one of the edges for doing the ultra hand Where it was like, I don't know like when you bend it a certain way the whole strip would just turn off Oh, that's dope. That is a nice idea It's a nude with heat shrink on brass wire That's cool. Very nice. Yeah, the brass wire is a good idea and I just so many Awesome touches just having like a little strip of light on stuff. Mm-hmm All right. Thank you. Are you ready to jump into this week's? Are you proud of that? Yeah Let's see it All right, this week continuing going on with the cases for The qualita supported round displays. Oh, I did not load my camera Extra camera. Well, you do that. I'm gonna load Nothing really it's um Still the same switch camera angles Do do there you go. All right So, yeah, here is the round display case for this guy finally got the lid on there. I'm using translucent because Feeling festive so everything's going to be translucent for this build I've got the yellow and the green going on there. We have the usb port so plug in unfortunately I don't want to use like any wires to sort of route this around so it's just going to go directly through and plug in there's just enough clearance for that And then the lid that goes on top And I got finally got this to snap in Yeah, so again not a true circle. It's like this weird Like oval you can see here Just because of the way that this thing is here And this part right here is the way it like bevels around so it's not like a real circle It's like an ellipse that's like squished So that was fun to figure out the shape with that um, I saw lamar did have the And one of the previews. What was it the 2.1 inch touchable? uh round display And that'll be a lot more easier because the touch um Thing that they put on top forces it to have that circle. So Hopefully that'll be easier in model But we'll have this guy and then I got the 3.4 inch this one is the touch display And I got the buttons on here Super happy with the ninja flex buttons on here. I didn't think it was going to work. It's just one strip. Yay Push down on the buttons. You have access to your usb port If we open this thing up, you still have I still have to add snaps into this But I just got the tolerances, right? I was like way off. I don't know how I got it instead of point two I put like point four I was like, oh no, that's for when you're fitting things into parts. That's the tolerance for that Yeah So yeah, uh, here's the strip for that you got the frame that goes around it that holds on the qualia Send it with this guy here, but it's holding on And then uh, yeah, it's just a little strip in here of ninja flex and this is the 95a so Uh, even bowden printers should be able to print this. Yeah, they do and you have access to all your buttons there Yeah, that's good. Great use of the tpu. Mm-hmm And yeah, pretty much it Was for some demo code and this one the video for this one. It's just going to be really highlighting the yeah qualia qualia Yeah driver for this because there's just so many displays. I think the Next one I'll do. Hopefully it's not too hard the uh rectangular. If not, it's just going to be these two for I mean, it's just about the board anyway, so Yeah, I think two is fine. Mm-hmm. It's going to be the popular one people really want round Yeah, um Devin has an idea for the round display wants to do a giant minion Yes I think it's steward. Uh, well Hang it, uh, for these on vacation, but I wanted to do the snow globe, you know, but that particle does it That's it'll be game. Yeah for a couple. Yeah. Yeah, well some more cool interesting eyeball, of course Yeah, the eyeballs big one Abominable snowman Eyeball or something. I don't know All day And I think the demo that uh lemar keeps showing off is like the best one the for the touch screen anyway Where you can change the colors? It'll be so cool. I has a little digital sketchbook for the kids, you know Sure. Yeah excellent for that And I think that's it. Yeah Yeah, it's getting the uh Taunts is going going there Cool. Yeah, uh after this we're going to do um A mars earth clock So we'll go with some fun kind of mid-century modern case design Using your model as a reference and then just kind of create some amounts Yeah, some sort of curvy thing for it to make it look like it's from the 50s of the future of the 1950s The idea is to have um, you know the the image of The round mars and then you tap the screen and it'll change to earth and you'll be able to see the different times And it'll have the analog hands So that'd be a cool thing, but that's after this one I'm just kind of highlighting the the board and the displays. That's our Python support the Arduino support And then a dedicated project. So that is the lineup Yep, they're cool Wasowski Yeah, Mike was asking is a good idea too All the Cyclops unite Get some single eyeballs Cool. Um, what we're prototyping. Yeah. Okay. We got 10 minutes left. Oh, we are ready for Um Community makes community makes. Yeah. So what you got there makes I think I have the video loaded up You want to grab it? This is some of the cool circular art from 3d bunny Seen a bunch of these pop up. We were laughing That usually the stringy that we see in the time lapses is frowned upon but yeah, that's when it's part of the design It makes it. Yeah And it's cool. Yeah, this is definitely like a A different style of modeling where you use these strings to create something of art So in this case, it's just Kind of creating these different Lines as a pattern. It almost reminds me like an Indian catcher a dream catcher rather Also, there are models where you can suspend A model inside the string that yeah, so that's another thing I've been seeing a lot of and 3d bunny Um on printables has a whole collection of these models. Yeah, they're so very cool And it's a great use of the um The rainbow filament. Oh, yeah, yeah One thing to note though is right right when I was done with shooting that I dropped it I'm even far down and you can kind of see a bunch of wires broke. Oh, I see it now a bunch of them did. Yeah Yeah, DJ Devon says like wow, that is some crazy, uh bridging Yeah, yeah, I mean look how giant it is. Yeah, it's so it's amazing that you can get one line going across it is delicate, but you can You know, it's it's a bit of an art So when you sliced it, it just knows to use one string and not like I'm guessing the um the size of it is just small enough to where the geometry is picked up. Yeah So, mm-hmm, I guess the size of it is what it is. Yeah No support This would be cool as nudes too. Yeah Yes, be insane String art with noodles. That's a lot of noodles. It'd be so bright and turn white I mean with the resistors on it's damn it down. True Cool, but yeah, uh, let me pull up, uh, uh, I already have showed the time lapse. Yes, let's look at 3d bunny Uh, so here's uh her Her model I think she did the color swaps Here's like a regular color single color great use of the um Of the rainbow filament though if you do And then, you know, some of one of some of their designs Or just a slew of these like Yeah, those right there. Where's the public models? There's some more string art here Some suspended stuff here's like a skull That's probably the one I could do next Yeah, right Maybe the quality ones. Yeah, you can see here how like the shapes Wait, let me get fed into it and they create the suspended thing So the idea is that you know, it's a whole art the frame is what keeps the Aligned in place I like the one where it's the raining on uh, what's his name? alone Yeah, I think I saw one where there's like a hand Suspended in it. There it is. Yeah. Yeah, here's like the rain where the line becomes the rain It looks like this umbrella is suspended So that's a super clever way Here's the cow this one. I think got an award or something featured With the cow. I think it's a multi material part But you can see the cow and its umbrella Very cute And on and on and on so definitely check out 3d bunny On uh on all the the printing sites That's awesome designs There's some more the vase with string. That's cool All sorts of fun stiff So shout out to 3d bunny for sharing their models for free On printables All right, so that's this week's time-lapse Tuesday. Check it out. We have links to the model In the description And now Let's check out Some community makes You only have a handful here First up we have a make of The tva time stick from the tv show Loki This was posted up by Michelle Tran And they say uh first time doing electronics project starting out just 3d printing came across Give it a shot. That's it. It wasn't easy. The project was listed as intermediate But I went straight into it following the instructions step by step 3d printing part was the easiest every part Needed no supports and it came out perfect easily screwed together with no glue I had so much fun with this learning the solder understanding how the feather and form Thing works. Thank you What? How cool that Michelle? This looks great. Yeah, very nice and Goal achieved All right, all right there A little bit when like the 3d printing is the easy part and the electronics is the learning part So that's kind of what our whole shtick is Not like that. The avenue to get them into that was Loki. How Loki's yeah, right? Yeah And the next one is another tba stick. This one is for candy Brooklyn this model is amazing. I had to reprint some of the parts to do it breaking But he fixed it with using four wall loops and a hexagon infill. Thanks for sharing He fixed the temporal loom. What that's funny Yeah, so you can pick whatever color you can sand it you can post process if you like or you just use a nice filament And here you can see how I think they're just gonna print the model you don't even have to do electronics if you don't want We're just cool too because they all just screw together. They all snap fit So that's really nice. And this was again from canon on printables And then the last one from this week is the lightsaber the rp20 40 lightsaber Darren posted theirs up. They said in the process of building the electronics love the design And they printed it in this nice Shiny black. Well, and there's the prop maker Very cool Yeah, it's funny to see two back-to-back Time-sticks because um season two of bloke It's the one from the past. Yeah That's funny Yeah, and of course you can get a tba time-stick from shop that disney, but it's like 100 Yeah, and that's probably not as responsive or Fun. Mm-hmm, but it has sound effects, of course We use not even that good Yeah Thanks everybody for posting your community mates. They're super awesome to look at Let's head back over don't swear Like our goal is to make things better than what they do for the For disney at the park. Yeah from mass manufacturing, you know, they got a cheap out to make it affordable. Oh boy. Did they cheap out? Yeah Yeah, they have nice looks though like the outer skin. You could always take The outer skin looks nice. The asoka lightsabers Great example. Yeah, yeah and upgrading it. Yeah, not all of that It's a better code. Uh-huh. There was a comment. I want to laugh at What was it? He he ha ha All right All right Thank you everybody. We're gonna round off the show. Don't forget if you want to pick up some parts Today's coupon code is led tree gets a 10% off your order Of course you get all the freebies if you hit those price tiers. We'll have a coupon code later tonight On ask an engineer But before then we have show and tell hosted by Liz Clark. Liz Clark will be hosting tonight. Come on The discord chat room. Say hello. We'll get an invite link to the stream yard So you can come on and share your projects your working projects your crafts Whatever and then at 8 p.m. Eastern time is asking engineer open source hardware news new products iron mpi and more Oh, that's what the question was. Will we be making a raspberry 5 case? Yes, yes, yes, I'll give a shout out here to um grab head Uh, yeah grab cad um mats Mate whose zelka nice post it up a really nice model of the raspberry pi 5 it's free to download I haven't checked it out yet, but it's in a step file. So you can import it into open shape on shape solidworks fusion 360 Yep, and it has all the things I think it's correct. Do they have the cooler the active cooler because that's A lot more wants she wants the I'll just add it to it You know add the cooler to it But it seems to be accurate I'll have to check it out. I have one on hand. I finally got my hands on one still in the box I don't think I I know it's like What works? Yeah, this was published november 2nd It's a new book. We're the os bookworm I'm not sure. This is still like Everything for it like everything broke, of course. Oh, let me put a link to this On discord if you want a CAD model But yeah, the case is being worked on With room for the active cooler on top. Yeah, definitely at least a case. So We'll see uh, when we get to that We do have the the qualia cases to kind of dish out, but then we'll get on some pie cases Maybe I'll mill one. I don't know. We'll see what's this This is part something about the Dg Devon talking about the sensitivity about the lightsaber you can uh, yes, of course Yeah by default set to the most sensitive Comments so people know how to decrease sensitivity Yeah We show a layer-by-layer on the design process of the raspberry pi case Maybe That's a good it's a good one. Mm-hmm. Yeah, I'll save it three one first though Although the case would definitely get more views though. Yeah, I think it'd be more Oh, no, they want the tree. Oh the tree. Yeah. Yeah, I think so. Yeah. Yeah, because it is a fun Yeah, all these are really for us in case we forget or something right. Yeah Yeah Yeah, I'll uh I'll take a stab at one Any other comments? You know, I think we're good there Oh, he wants added to the uh, the code page for that the sensitivity adjustment for that Is it better to do a github? Issue a pr. I think you can do a pr. Yeah, if you want to add a pr. Definitely. We'll take a look at it Because I'm way more easier for yeah Because then we just bring in the code change. Yeah, we need the receipts and for for us not forgetting to yeah It's easy to put it in a task that way Exactly. Yep Yeah, and I still have a backlog of CAD parts to catch up on so Yeah, we uh, we were very busy these days But we appreciate you for um Upping us out see And since anybody's still sticking around the Raspberry Pi fives Get launched. I think Live on the show Live during ask an engineer. So yeah, that's the best way to do watching. Yep. Um, they'll say when it launches So just be on the site That's all I can say Yeah, it's a great way to So The gift to y'all I don't think the coupon code works on Maybe it does. I don't know On what on the pi five? Yeah, because the margin is raised but then I don't think there's any money No, I know We sell them at a loss Everybody does I think everybody does yeah But we sell them when we have them, which is a lot better than the backorder Yeah, all right. That's it. All right. That is it. We've exceeded our hour long But thanks everybody for coming on the show everybody in the discord chat room. Thank you so much for tuning in We hope you're inspired to work on some festive projects We'll be back next week, but until then remember you make a great day Bye everybody. See you tonight
