 Hey, what's up everybody? Welcome back to another 3D Hangouts. My name is Noah Ruiz. I'm a designer here at Adafruit joining me every week It's my brother Pedro. Good morning everybody. I'm Pedro. I was creative tech here at Adafruit And every week we're here to share 3D printed projects featuring electronics from Adafruit. Oh Yeah, this is the show we combine 3D printing and DIY electronics to make inspirational projects Hello, everybody. Welcome to episode 341 It is February 21st, 2024 We're hanging out in the Adafruit Discord server in the live broadcast chat channel Say a couple of words to welcome everybody as they come in. We're streaming Live on the four networks Facebook, YouTube, Twitch, and X Hello, everybody. Welcome to the show We have some prototype projects Some shop talk, community makes, time-lapse Tuesday, all that and more on You guessed it 3D Hangouts All right. Hello folks if you'd like to Join the Discord server the URL to that is at the top here at discord.gg slash Adafruit Good morning. Jim Hendrickson, Duwester, Squid.Jpeg are all hanging out in the live broadcast chat channel And on YouTube we have Samur Mosa. Hello I'm gonna kick off the show with Adafruit.com slash free and we'll check out. What are the free deals going on this week? Similar to last week if your order is $99 or more you're gonna get a free PCB coaster with a golden Adafruit logo If your order is $149 or more you get the PCB coaster plus an Adafruit KB2040 That's the lovely dev board with all the fancy Features like a STEMIQT Running off the RP2040 and tons of GPIO If your order is $199 or more you'll get the KB2040, the PCB coaster, and free UPS ground shipping for continental US only And if your order is $299 or more you'll get the free shipping, the KB2040, the PCB coaster, and a circuit playground express These get automatically added to your cart as you order And on top of that you can use our coupon code, which is good for today It is camera box Camera box I wonder why you got a couple of camera projects coming up Camera camera camera camera for the next, I don't know two weeks three weeks four weeks A month. Hello Brent is hanging out in the live broadcast chat channel. No We have a surprise for Brent Coffee icon for coffee emoji double espresso All right, how who's gonna start off a drink we don't have a Learn guide to release this week because we have been in the development iteration phases for our upcoming projects Hey, yeah, so one one. Let's see. Yeah, it was supposed to be the itsy-bitsy ESP itsy-bitsy 32 is what was supposed to come out this week. It'll come out next week This is just a tiny little case for the new board has a stem on there And you can add some stem boards on the front here and this is the WFL version So you can add an antenna. That's what this little hole is right here. So Those should arrive sometime today the little adapter for it with the antenna Update the size of this case to fit and I think just gonna use like W LED to run some LEDs for it with it And it's just a nice little tiny case. You have your Access to if you use headers or on the top if you want to have them point out from there And then I'll just add more additional ports on how the LED strip is set up So it's a nice little itsy-bitsy ESP 32 case And that'll be next week Very cool They're still in stock Yes, these are brand-new Lamar has a whole story about these but she started design in 2020 And it just got sidelined for all the part shortages and the continuation of things going on but Check it out. It is a it's got the ESP 32 Pico Chip so it works with W LED It's the dual core to 40 megahertz It stands a processor eight megabytes of flash two megabytes of ps ram It recently got the circuit Python build for it. Shout out to listen putting that together You got a built-in 70 deport And you have those two buttons which are nice for programming Bottom you have a little footprint for a I suppose a two-pin JST battery connector if you want to do that That's really nice It's you bitsy format so so tiny Talking about I want to use it in a project or something just because of the size of the Wfwfl Antenna on there. I still have mine in a bag. Oh, cool. I need to actually I'm telling you the wrong version Where's the other one? Oh Yeah, so in the product page you have the PCB antenna or the WFL antenna depending on your use case They're the same price It looks like people have purchased more of the WFL version. There's only forty three left this time. Oh nice Yeah, I'm really liking that one you know Well, this will work with whipper snapper, right? So there's the board or definition Perhaps I'm not sure Because obviously I'd like to do a whipper snapper one like a tiny little case for it Not yet. It's not yet, but just quit at JP agrees great. W my WLED microcontroller. Yes Yeah, that was the first thing that came to me. Yeah, I'm running these strips here You can see the strip I'm running that Yeah, it looks very dim in the camera. Oh because the sun's out. Yeah, the sun is out See if I can do like a solid color or color loop. I show the little small one, but And we'll show it off next week. Yeah, yeah button pressers on it. All right So that's that we'll come out with that next week another one of the prototypes that we're working on is the updated servo Camera, so it's gonna be a little like an owl looking and cylindrical type Camera mount for that and on the bottom here. It'll attach to the servo It's this guy here So I just move the entire assembly around and this is held on likes a lot of those shoulder bots That we make it's just magnets. So this base will double as you know, you're for their desktop so you can just sit on the desktop and then this metal a little shoulder thing goes on here I Just attaches like so so you can have a little shoulder bot moving around Scanning the faces that you're walking around in the public. I should be okay for taking photos people like that Just pops off like that And it's around so this will go on with a mount that is attached to The memento thinking it'll be the tripod framing that you built for it in the last so sure We're about settle code down and then have a spot to insert and then screw the The servo into like show Mm-hmm have your LED to eliminate and then give you some feedback like green yellow and red Based on whether the accuracy of scanning a face if we turn this going on Oh, you know what I sent the the other one that had the face tracking demo. I sent it to Brent But we're talking about the way that this assembles together it's just too little Tabs with the screws on there and you have a good field of view on here. We're discussing the maximum height How far you can be away from the screen until it gets obstructed it's like 24 millimeters Oh, yeah, that was the first thing I was scared about. Yeah, I don't know having to put it into a cylinder I can't believe it's un-extructed and I like the other half you have like this kind of cool viewfinder going on Viewmaster from the 80s Kind of has a new master taper in there because you print it at an angle Yeah, it helps as like It'll definitely help block like the Sun sunlight Span this just a little bit like point one five I had it expanded at like a point two and I could see the edges. I didn't like that So it's been it just a little bit more so you can see more of you can see how the resolution up here is getting cut off Yeah, and that a little bit. Well, I love the shape. I've been getting some vibes from sort of sort of a minion But also you to round cylindrical Robots Jim Hendrickson says the dome shape resembles a little observatory. That's not cool Yeah, yeah, very cute very kind of minimalistic But I think it's very nice Cool mountain like that already shown before I will move around here and the Magnets that we're using are the ones that we use for building our like the lapel magnets for We're using them for I think for like attaching Circa Python or Circa playground expresses to like make a badge So we have plenty of these and then to make the magnets a little bit more stronger. We also have these other Neodynia magnets in the shop as well and that just adds more Power to it Because I'm sure the weight is going to increase on it So I want to make sure that it's not like loose when it's on you. This is yeah, that's pretty magnets Nice to think yeah, it's really It's really small diameter. Yeah, and then this is sandwiched in with one of the servo horns on there So that's how that is attached off real quick Yeah, once I fully assemble this there is a screw that goes through the Servo horn to firmly attach it so doesn't just pop right out That's how that guy is working Mm-hmm screws and just hold it all together Then the only thing I don't know how to source is this guy this came from one of the puppets that you can get at It's animal kingdom Yeah, Pandora little shoulder puppets, but I think like any sort of metal that you can bend or Yeah, they even have like the little plate ones for having a little plushies Everybody wears on their shoulders at this or yeah Where we get the ideas for these So yeah should be nice way to have a shoulder bot without having to have usually like you know People have like you know belts and all this stuff over yet. Yeah, that's nice to curve around your shoulder and a little bit of silicone Bumper it kind of grips a little bit to your skin Yeah Yeah, that fits good doubles as the base and I'll add some little feet on here, so Hmm when you put it on your desk It's not sliding around right Cool. Oh My god looking at the comments here squids and the yassa accidentally broke two magnets when they unexpectedly smashed together That is always my fear when working with these magnetic projects Super careful. Yep caution Then I think that's it that's all stuff that I'm prototyping Yeah, okay It's a case next week the UofL antenna and then either the week after that or following robot, if not, we'll do Robot, yeah Cool. All right, I'm up with my prototype Using the memento camera as well. This is What is this? It's a little birdhouse. So this is going to be a kind of DIY IOT bird feeder Brent wrote some code That uses a PIR sensor to trigger the camera shutter So whenever a bird lands here, hopefully it'll take a picture of it and We have a water proof enclosure This is the small water proof enclosure that we saw in the Adafoot shop. It's injection molded There's another half of it that is made out of polycarbonate. So it's clear And it has like a internal gasket rubber gasket in these plastic screws and it's fully waterproof So it's really nice. We when something's outside you really want to be waterproof So you can 3d print the things around and then it's mounted to the back plate here with these four screws and hex nuts Really really nice case. It's got great technical drawing. So I was able to model it up infusion So get the things right. You can't see it, but there is a 3d printed Bracket that adapts the four standoffs on the memento to the two heat set inserts that are already pre-installed in this enclosure, so it's really really versatile enclosure It just about fits the memento camera. You don't have access to the screen But that's okay much like the doorbell project that we did a couple weeks ago You won't need access to the screen because they're using Adafruit IO And the feed to display the image So I got the battery here you can't fit like a 2200 milliamp battery somewhere up here So I might opt in to do that But the PR sensor is soldered to a 3-pin JST connector that just plugs in to the side there There's just enough clearance there for it. Of course, you don't have clearance for a USB-C cable But you can use Adafruit's Online web workflow website to debug code update files and things like that, which I've been testing it works really well And yeah, this is a pretty cool DIY IoT bird feeder I came up with some fun details for the roof. You've got like tiles and like this kind of cool texture here It's up to any supports The hopper, you know, it's it's a parametric design so we can make bigger smaller if you want But I think for just one bird and testing It'll work pretty well We have some hooks here or some some holes some slots for either bolting to something else or adding hooks or something We have yet to kind of test that out, but One of the things I found is that this PIR sensor With the polycarbonate clear covering over it It doesn't work at least I couldn't get it to work I played around with the the built-in Potentiometers for the sensitivity and the delay I don't think a PR sensor works when even when a clear thing is in front of it because it's like it just sees it as a solid object So what we're going to do is we're going to drill a hole in that polycarbonate But also why not 3d print the thing so I have here is a plate That will just press it here. I'll print out a tpu A flexible filament gasket that will go in the inline here and then we can reuse those plaques plastic screws You know, you're still going to have an opening for the camera but You know, this is one of those things it's not going to be fully But I think with the polycarbonate Front plate and you drill a hole you could probably do a gasket and tpu or just use hot glue to really seal This pIR sensor to this plate the polycarbonate injection mold plate But otherwise I think it's going to be a pretty good solution You got plenty of room in there for some bird feed and uh That's pretty much just a bit. Let me show you the uh picture I took earlier this morning on my Adderfruit IO dashboard Well, it's more of the feeds but Here is a picture of adobot Pretty much just perched up right here So he was kind of like this Size-wise we were saying it should be good enough to get like a yeah So the distance, you know, I'll play with that. Hopefully the bird will be in frame And uh, you know the the pIR sensors position pretty low because that's where the bird's going to be like pecking Yeah, um, so hopefully that's good. Um It'll be tricky kind of angle the camera lens to be like pointing down Um, so that might be an issue, but you know, we'll see we have yet to see And then uh, what is it? What does a bird look like compared to a squirrel? Like does it? We don't know yet But you can see here. This is the image that the uh that it captured with the pIR sensor Um, yeah, so that's kind of what I got going on little bird feeder Yeah, that's oh Maybe in a couple weeks We'll see That is super cool. Fetty is working on a um, AI bird song identity product bird song And uh, that's cool. Wow. There's a chart here that shows you um, some data here on the different birds It's funny. I actually go around and save like bird songs and then play them back to the birds As I'm walking around nice That's funny. Yeah, and you can play them back and uh, how to communicate with the bird Yeah, although I think it makes them mad the um cardinal, especially Oh, yeah, don't do that scooping down at me. So I'm like, ah, play the song back to him It's a it's a cry for a battle cry something Um, yeah, so uh, I'll post this up Brent I've been working on it in the background just kind of to get queued up so that when we're done with the shoulder bot We can focus again on the the bird feeder I think having even just a bracket for the weatherproof enclosure is a good useful Mount so that you can enclose maybe you want to throw this outside and take some time lapse outdoor time lapse photography Having a waterproof in this enclosure is nice and having that pcb bracket is kind of essential because otherwise just kind of floating around in there And we currently have if you go to The Adafruit shop Let's go to a small weather And you should see it momentarily here it is. This is it does what the front cover looks like again. It's polycarbonate. So it's shatter resistant Um There's a whole data sheet on the material that they use. It's some really good high grade abs plastic mixed with some like special resin, but there you can see the internal um mounting Standoffs they had they're threaded. They come with screws these screws are plastic And there's a gasket you can just make out the gasket here the white thing on the outside that's uh That basically seals um the two pieces together and it prevents from any moisture to getting in there And uh, yeah plastic screws, huh pretty cool Um, so I have a model of it. I'll release that. Um, you can fit about an Arduino size thing in there Looks like a promo proto just about fits, but that's nice. Oh, wow. Yeah, we're just about the fifth corners. Yeah But I haven't used this yet and uh, look at that. Even the dimensions are on the outside for the mounting holes. It's pretty nice Yeah, um, I really like it. It's a little chunky for this project. It really makes a lot of sense Oh, no, if that's all the stuff you needed to Yeah Looks like it's been used a few times mailbox notification. Uh, trinket bluetooth alarm system And um, yeah, I don't think you'll need to access the usb other than charging the battery Um, but it's it's relatively easy to take it apart. So This is one of those caveats. I think charging the battery will be a thing. Yeah Um, but yeah, if you want the weatherproof case you can pick one up See any questions? I mean I need to expose my usb cable on the roba Hmm Maybe Just so it could be powered because Especially you're walking around It'll drain Yeah Well, you have plenty of room in there for bigger battery. Maybe go with the 2200. Yeah, um Yeah, yeah, that should you have a nice little bit of cavity on there, but then the caveat is oh, no No, it's gonna weigh more Exactly. Oh, no, I want that waste more power trying to push. I have your object. Well, you can use a bigger servo Uh, or just have the wire Coming out into my back pocket with the background. That's a good idea too I'll look like a vision pro user. Yeah, I think that's standard. I think External wires coming out. Yeah Although I used to do that with the google glass When I was charging right So is that a stock please sign up to get notified when they're back in stock And what other product did we showcase? I posted the OPR the oh microservo Yeah, these actually come with a jst 3 pin. So that connects to the what I'm hosting. Yeah, really nice No, sorry. Yeah. No, I had one that That's why I didn't send you that one Sorry Yeah, so that would be nice. I had to plug into the memento And then I wish the pyr sensor came with one of these guys because I had to solder directly to it It comes with this little thing, but it's not, you know It only goes to that and like it's too bulky to fit. Yeah to fit inside the case. So You could I think I used the jumper The socket jumper cables work Okay, we'll give that a try And I think those are all the parts Yep And that's what we are Prototyping if you want to pick up anything in the shop that we talked about that's in stock you can use our 10% off a discount code Camera box. Ah camera. That's why we call the camera box. You have a box. I have a box and they both I got a cylinder cylindrical box, whatever We um, said he is saying uh That playing back the bird music is illegal in parks Oh, wow. Yeah, I did not know that it makes sense though They're like endangered birds and stuff and he has a story here on Saw some toucans. I haven't been back So he said Yeah, I don't I guess yeah the scale of the birds we're gonna get you're gonna get like, you know What do you have around like cardinals and stuff and then we have our big old cranes here So I think his head is probably gonna fill the frame how close they get. Yeah Yeah, if anyone has any fun ideas for the bird feeder, let me know Be interesting to see what animals approach it. I'm thinking squirrels and birds. I don't know what else I'd show up the scale because we were talking about the the cranes just had their little babies So I'm gonna see how big the baby is so we can get photos of baby Yeah We're doing on timing. I think it puts the whole link so far. Yeah, we're we're hope we're thinking of probably a pretty short show because uh No lord died this week, but next week You can jump into community makes Pretty cool little fidgets Yeah, all right. Let's play the video. Let me that's muted All right this week on community makes we got this cool little stretchy fidget as uh I'm liking the way this is stretching these little bars go between these circles in on each uh in on each other And they stay all together allowing you to move Move them like across themselves until they hit like the end of the wall there And then they also have a couple of different shapes. They have a circle as well That's not like a square, but man, these are difficult to print They look difficult to print Because anything with a thin body thin walls. It's the whole thing is thin walls. It's a lattice Yeah, um, so there's a ton of attraction. This is a great It's nothing but attraction for tests for your 3d printer. Yeah I first saw this on uh, I think instagram But I looked at I was like, oh wow, this is a really cool printed place And it showcases how you can uh, you know create um this mechanical hinge Um with this, you know lattice. It's pretty cool. I haven't quite seen it before Um, it's difficult to tell on a single extrusion print. Yeah, what's going on, but it's easier to print on that I'm guessing that's why because you're changing the the The head the color as you're printing each layer And I think that's what was pulling it away from the um the bed Yeah, it reminds me of those science toys that you would see at science museums It would be a ball and then it would expand out to this giant thing and it kind of showcases how You know mechanisms can uh kind of hinge down to change its form So that's a pretty cool principle Looks like a dual extrusion, of course Yeah, with the colors Where am I? There it is. So it is a free design. It's from tumbo designs Comes in different shapes Dual extrusion single extrusion Uh, there's a video about it. You can check that out Um print settings make sure you have a lot of bed adhesion Yeah, we'll film it. I used a brim So if you like one millimeter brim Yeah, I did have to do a ton of cleanup. I'm just removing it off from the bottom But it cleans up pretty good. Yeah, and then even the fails you can see this right here at the bottom Because of the rest of it did not fail. It kind of carries along with it. And then you can't tell It was a fail a color combo there Yeah And I really like this um really good inspiration for if we needed to make a fancy hinge like that There it is Be as part of the whole I don't know. Is this a wing or something I could be Yeah, I don't know Servo on this. Yeah, it's a good. It's a good concept, but uh applying it to something Else would be interesting. I don't have any ideas right now. I had spaces in there, but yeah, maybe something Maybe we'll come up with something Uh squid at jpeg is saying uh squirrels around here will chase the birds away from the feeder. I can see that I wonder if there's a way to Remotely like trigger the buzzer to scare them Go away or something. You know what I was saying. Have a servo Trap the uh, not the animal but trap to cover the electric you had enough, you know You've had enough like No That'd be kind of neat the uh one of those squirrel capturing devices But no, we just want to feed the animals. We don't want to harm the animal It's a trade, you know, we give them food and in return we take their likeness and sell their data online Well, the squirrels here eating through the car, so They don't get a free pass There's the squirrels with the mice squirrels The mouse and a rabbit We were on a walk yesterday and we saw what we thought was a rat. It turns out it's a muskrat Which is the first time I've seen a muskrat. It's a bigger It's huge. It was a huge Mars, you know animal Rodent, I guess you call them. They had this giant thick tail. We caught on video It was walking so slow because it was so heavy They had eatants. I don't know what it ate, but Oh, there you go. Squid says, uh, squirt it with a jet of water Funny. Ah, like a cat on your counter Yeah, yeah, it'd be cool to do something with one of those Valves that we sell that are mechanical All right Yes Let's uh check in. Let's see the first one is We got a remix For our heat set insert rig. This is by one two three cure one two one on think on sorry print of printiverse printables.com This is an add-on to the project It it's a bit of a storage piece Combined with the counterweight Um, it has these little holders for the cnc kitchen Uh add-ons for the soldering iron That's a pretty clever use of the counter thing because these are brass and they're going to be heavy anyway And uh bolt them in place. So when you're, you know, swapping out different, um, sizes for your heat set inserts You can all house them in the same kind of thing, which is a pretty cool idea So I love seeing these additions. There's so many add-ons to this project. It's really Kind of developed the life of its own. Um Yeah, so it's cool. It's cool to see All right shout out to them for posting that After that we have a make From zen re on printables.com It's the circuit playground snap fit case If you have a circuit playground express and you want some way to kind of You know mount it to something else or just protect it. You can three-point this simple snap fit case um Zen re says, uh 80 fruit snap fits are always a joy I find it hilarious that we all install the cpe upside down But I really like how that tones down the neopixels and uh protects the board Uh have a protective case gives me some peace of mind when I lend this board to buddying makers Yes, very nice And this comes in different sizes as you can see I think we printed a Star in some other shapes After that Boss for the past but still relevant an octoprint rig for your pie tft 3.5 inch This is a sort of a remix add-on For a viper printer And it kind of angles it um So it's got like this additional bracket that Props it up at an angle and it holds houses the pie The raspberry pie in the uh the pie tft touch display And that that was our original thing it has a stand but this one looks like it You know attaches directly to the printer, which is nice Okay after that Another blast from the past. Uh, this was posted up by zarith They said I had to edit this a bit to align it to his own lamp But it looks nice and it fits other ikea lamps in their apartment This was a uh a lamp shade that I designed It can be dual extruded or a single extruded but the idea is it's geometric Has a diffuser I originally printed this on a dual extrusion ultimaker, but they printed it uh Just the uh just the geodesic bit of it for their ikea lamp It's kind of it's kind of a new design it prints without any supports amazingly But love me some triangles and thanks zarith for posting that up After that we have another uh add-on for the uh the heat set insert rig This is um, I needed a quick and easy way to mount and unmount a pencil soldering iron came across two good Designs and combine them this is supposed to buy again one two three d or one two three q or one two three So here's a photo of the clamping mess mechanism So you can easily take the soldering the pencil soldering out of its housing Pretty cool Pretty cool, huh Yeah After that we have our first make of the led holiday tree using led noodles Looks really nice. Just posted it by afp 316. It was a perfect christmas gift. Oh, wow let's see a bit of a challenge to build just because it's like a lot of a lot of wiring I remember it being challenging especially when I documented it um But hey, it worked out. I'm glad it worked out and you have all the different colors and stuff that you can uh apply that you can use rather All right after that we have another make of the zelda breath of the wild guardian sword with new pixel IDs Supposed to buy ross Hendrickson modified it to fit the bamboo bed and went with the cheap fairy lights embedded versus the new pixels It's four dollars versus a hundred dollars. I still need to add some black accents mice on loves it That looks nice even with fairy lights. It's it's gonna be fun time Good use of the colors too. Very cool. Yeah Yeah, this was uh, we need to upgrade this We're talking about what board actually use probably a prop maker most likely. Yeah Yeah, there's no sound effects in it, but uh We just need to update it so it's no longer Arduino and uh You know a low power Proper mounts. Yeah, we can add accelerometer and sound effects all that stuff now with that. Holy crap Yeah, it's pretty bare bones, but at the time it was still like really cool Yeah, lots of makes on this one on Thingiverse especially because it's It's kind of dated now as you can tell with the electronics, but a lot of folks still are making it which is super cool Maybe we'll make a some zonai Is that what they're called the zonai? Maybe we'll do something like that ancient sword something And that concludes the community makes I think everybody's you're posting up your makes. We really appreciate it That's the show Like we said, we're doing a low-key shorty bagooty working on stuff Don't forget if you want to pick up anything in a different shop You can support your maker habit and a fruit as a whole with uh purchasing some parts every now and then You can use your coupon code Camera box and get 10% off your order All right Anything else later? I think that is all for the show. Yeah Yeah, yeah, yeah, um I don't have any new tools or anything so I'll go back um Yep, it's cold here up here up north northeast 30 degrees I think that's all we got is all we got so uh tonight We got a special show until hosted by melissa maker melissa will be hosting tonight. We invite you to come on At 7 30 p.m. Eastern time is when it goes live, but you can join in maybe 10 minutes before that On the eight of your discord server. We'll get we'll give you an invite code so you can share your projects We'd love to see your stuff what you're working on work in progress retro tech arts and crafts All is fair and fun And then after that at 8 p.m. Eastern time is asking engineer with mr. Mrs. Lady ada open source hardware news new products ion mpi and more Tomorrow is jp's product. No jp's workshop Check in and find out what jp is working on Friday's is uh scott's back. So I need to update this deep dive with scott And every friday, sorry every friday at 2 p.m. Pacific or 5 p.m. Eastern On the weekends sundays is from the desk of lady ada you can tune in see what she's prototyping A random evenings on sundays Mondays are circuit python weekly community meetings Um, I think it's around 2 p.m. Or is it 1 p.m. Maybe 2 p.m. You can always check the show times. Yeah, and you can contribute and that In the discord server And then tuesdays is jp's product pick of the week Or you can get crazy discounts up to 50 off select products Always a good time with jp's product pick of the week on tuesdays ramping right back around wednesdays start off with our show And then the two shows that follow in the evening wednesdays are big for us Thank you really so much for uh watching. This has been an aid of fruit production You can get another coupon code tonight, of course on ask engineer, but until then Remember to make make a great day. Hey, we did it See you tonight
