 Hey what's up folks welcome back to another 3D Hangouts. My name is Noah Ruiz. I'm a designer here at Adafruit. Joining me every week is Brother Pedro. Hello. Good morning everybody I'm Pedro. It's great to have you here Adafruit. Every week we're here to share 3D printed projects featuring electronics from Adafruit. That is right this is the show we combine 3D printing and DIY electronics to make inspirational projects. Hello everybody welcome to the show this is episode number 433. It is March 6th, 2024. Hello everybody hanging out in the Adafruit discord. We are hanging out there. Take a couple moments to let folks come in. We started a little bit no not late I guess maybe a minute late. We're on time. We're on time. Welcome everybody to the show. We got a packed show. We got a new amazing project. It's a collab project with Brent Rubel. It's using the Memento. It's pretty amazing. This is the first this is the first time we've ever done anything like this. We have some fun prototyping projects. We have a shop talk segments, new CAD files. We have a handful of community makes and of course a time elapsed Tuesday video. Hello and welcome to the show. Oh my god why did they put this show comments button right next to end stream button. Oh wow it is pretty cool. Job UX designers fabulous job. I'm sure there's a prompt that says are you sure you want to end the stream but let's not test that now. Later when the show is over. We're going to welcome folks in the chat room Pedro while I queue up. Good morning. Shout out to everybody hanging out in the discord on YouTube on Facebook. YouTube Wester we got Jim Hendrickson. Brent's hanging out. We got Erin, Liddy on the YouTubes. We're also on. Can I say Facebook? Twitch and X and the other one LinkedIn. It's all working. All right. Excellent. Well hello everybody.

All right, shout outs to Squid.jpg and has a dental road. Hello and out. Jim Hendrickson is hanging out and on YouTube we have Erin Leedy. Hello, welcome to the show. All right, all right jump in right into this week's project. This week's project is a release of the face tracking little robot featuring the memento camera and just taking a look at the viewfinder here you can see the bounding box that it's making on my face and it'll just follow me. How freaking cool is that? This little robot we came up for the design we did come up with a different one prior to this when we were first prototyping. Let me know if you want the design for this in the lease. This one's more for development so it has all of these stemma like little vent connection parts there and then you can have access to all the ports if you need to do some troubleshooting but the final design is this simplified one that just has the USB little port on the side here and the way that this mount is just press fits on that and then you can have access to the whole board on the back so if you want to do additional troubleshooting I'll just show off how that looks that's how it is all assembled. So I have this frame part that is connecting a servo down here to the base plate and the servo or the horn is sandwiched inside here with one of our magnetic pins so you can attach this to magnetic surfaces and then if you want you can pull so I didn't screw this one on so the horn just pops right off and then you can attach it to one of your like a tripod. I enabled this and this is how I should have been shooting at Star Wars with one of the tripods so I could easily angle things because my thighs are still on fire from having to hold the camera a lot to get all of the shots and then your face has to be like you know pretty in the field of view so I can draw its bounding box at a continuously get down to its level because it wasn't as high on some of the posts that I put it on for popping up for the photo in the video so yeah definitely recommend going with a tripod if you want to have this mounted on a desktop or anywhere else and what I really like about it is it's the way that we're showing it off look like it was like a robot to scan you before you go into an entrance or something like that so a nice little way to cosplay things. Let's see pretty easy in terms of all of the parts that print out it's not too many you're gonna need supports on I think just like the tripod section of it and then for the back piece just this little tab that pops out here that is connecting it to the front piece and that just uh just fits in like that because of the shape it like sort of hugs on to the front part of it and then yeah you still have access to the bottom there if you need to run down any additional wires and yeah so when it sees your face it'll light up the led put its little bounding box around and it'll follow you and Brent did an excellent job of explaining you know some of if you want a troubleshooter how it's actually doing the face tracking and get access to the code and all that we'll go over it in the guide section a little bit but yeah um I think the thing that we want to brag about with this is like what other face tracking robot toy is there out there like we were in galaxy you know we've been there for many years and they have never sold a face tracking robot if they did they'd probably like $250 or something this is like what 50 bucks in parts I want to say baby close $5 servo like the board itself is like $30 like and then the software for this they wouldn't make it like this for you to easily know where it's open source USB where it'll load up even though it's you know you have to use the yesp tool to get everything in there you still have access to do that so I think it's a monumental achievement of being able to create something like this and then just give away all the plans and I have the code ready to you know sort of peek at you so cool like having multiples of these together and like I think the first thing I thought of was the haunted mansion room where all those oh they would follow you yeah yeah so halloween projects and things like that there's just so many things you could do with face tracking so cool I got like speechless on uh yeah yeah it's amazing historically I think I've only seen uh Raspberry Pi projects which are like really very chunky it's hard to be portable with a Raspberry Pi and running all the Linux software like OpenCV yeah it's pretty cool so big shout out to Espressive for sharing their code and Brent of course for modifying it and making it work with the servo and the neopixel ring yeah very cool sorry that you mentioned Raspberry Pi I have to rag on them for like startup time let me turn it on and here's your startup time that would not you could not do that on a Raspberry Pi we'd be here for two minutes as it booted up and then oh no conflict so immediately boots up you can see that all the graphics for the overlay on there it's tracking my face one thing to point out does not work on robots I try to put it at a robot face yeah the other test we did was uh I think the three scan of your face like you mean those little toys kind of worked for that kind of works yeah yeah so any face that looks like a face basically you can be wearing glasses um hmm does it work with like a drawing of a face I have not tried a drawing right like what kind of face what are the limits of the face detect we're getting really philosophical and that is so cool to have a robot that can track your face yeah I really like the design I like how easy access you can just break away the other half of it right through the all the buttons because like that's one of the hardest parts is like uh enclosing the very boxy nature and having kind of limited access to some of the ports and stuff it's like it's kind of a design challenge so having the first version is really essential yeah because like I don't know I need to have access to all my jst pens usb um so you kind of constrained a lot to that shape but this really shows so you can kind of encapsulate it in this you know very non conforming shape the cylinder uh and then you can't move the lens you're really stuck to the lens so that was a really cool way um to kind of have both things where you have a nice round cute shape but then you can pull it apart easily and then just be acting being able to access the uh the on off switch yeah and that real quick showing what it looks like when you mount it to your yeah when you're selling on your shoulder so yeah really elegant easy way um have a metal plate that kind of wraps around your shoulder and the neodymium magnets for the wind um having the tripod thing as an add-on is a really good idea too because just so many things are um so many different mount ways to mount things to a tripod plate um yeah i didn't want to go the route with like you know having to have a thing all strapped to you and whatnot yeah they can get really complicated really quick so yeah this is a design we've been using for quite a while now where we just magnetic pins magnetic pin to attach and then just having you know the horn that can just pop right off if you do want to have this secured you can use the included screws to attach the actual horn that's inside here yeah now you can have a anytime i use the server i always tend to do the same where i make my 3d printed part wrap around the existing injection molded horn because it's really hard to kind of print something in fdm that is uh that has those splines those those very fine pitch splines and that's kind of what makes it the servo horn like perfect is those splines which got going on the other robots following me on the uh tv oh yeah yeah so cool that that that works i'm gonna show this on the show and tell with the film lamar be like hey this is a demo that you can control yeah just moving around yeah cool so yeah what's uh it'll be at its start position before when it's looking for a face and then it'll follow you when it does find it and then when it loses the face it'll go back to its reset back to its start position and that's how you can adjust where you want your your horn to be so you can pop that off and re-angle it so it's you know aligned with the way that this metal um little shoulder thing is because it's just like a little rectangular shape you can you know have it line up with that and to have a really good magnetic connection we did add additional magnets we do sell sell these in the shop as well and these are just you know sort of the poke out from here the reason why we use the metal pen one is just because of the shape it's like enclosing the two magnets and then we can use that to press fit inside here just makes it easier as a complete assembly um yeah what else can we talk about we have some good comments and uh discussions yes right in the house so jim hydrickson was asking does it have cat detection and brent says it does not have cat detection it was trained on faces and we didn't train it oppressive did the training so all the training data is like embedded in the expressive code oh wow and that was extracted by brent and he tweaked it so that we work with the servo and the binding box strolling on the tft all explained in the guide we'll take a look at it in a minute just try to dog it does not work on a dog either yeah no animals just human faces um dj devins saying he agrees that servo splines are damn near impossible to print with ftm they're just too tiny yep oh probably the resin printer you could but you know it's easier to just model your thing around and existing exactly yeah yep and some cool gifts from yanni very nice i like that and yeah you know if you know the stl and the step file they're all available to download so folks want to add additional things to it i would love to see j odd j um yeah have his spin on this like to have a real track face track it would be super cool to see from j mm-hmm yeah definitely need to work on top of a word i completely you know just take apart use all of the um the uh the geometry for other things yeah we have 3d models of the board and servos and all that stuff too cool yes brent agrees we love to see odd j remix one of these yeah or create something from scratch whatever cool let's uh jump into the learn guide are we ready right you can drive it go back over to my guy where am i go sorry all my robots are covering my screen let me actually turn these off so i'm not oh distracted point out we have a little holes here where the tabs are if you do want to you can use uh screws to completely you have this locked in yeah but i like how this serves as an indicator that it's on or it's charging you plug it in oh yeah very nice and then yeah just to get in this is how you turn it on off to access the little switch here that turns it off yeah all right jump into the guide oh quick that's your screen yep super detailed learn guide on all the code walkthroughs troubleshooting um anything you want to know about the uh yeah the origin of the code is originally a camera web servo demo you wouldn't think that a web server a camera web server would have face tracking but it does i am trying to go full screen but my cursor is like trapped in this bounding box right so yep what you said all of the origins of the code were to get the original example for it all the files are going to be and then of course all of the uh parts um we listed like you know the cheapest uh servo that will work with but it also worked with the metal one i did try both uh this is the five dollar one and then the uh the all metal geared one it's like ten dollars uh sounds better um you know if you want to have like a bigger battery it shouldn't be able to have more torque to uh turn that if you have add more weight to it but the you know the cheap one works as well um trying to keep the cost down as much as we can the uh just be cable the um i don't think you actually need that st card i think it's just stored in memory but yeah i don't think you do either but it's very if you want it of course the tripod adapter screw if you're gonna put that on the tripod battery and then some of the cabling down here the jst three pin plug cable that you're gonna use if uh you have a servo already and you want to convert it to a three pin jst the magnetic pin back um jumper wires to when you're threading your led ring through the enclosure something like that there's holes um you want to have some way to reconnect it once you thread the wires through there and we're just using socket and pin um jumper wires to connect the led and then your various screws think uh man i'm glad you had ordered the 20 millimeter long m3 screws because that is the perfect size for going through that you know really long standoff that is on the memento board all the way through that into the um case so you're using those to mount the actual frame yeah going through there and then through the memento and then out into the standoffs that are on they're built into the front face yeah yeah those um the m3 m25 by 6 millimeter for mounting everything else like for assembling the the frame that holds the servo so these screws right here and then of course all these that are holding the sandwich together with the uh uh server horn okay yeah that's it moving on to the wiring brent uh the uh for seeing a diagram for this pretty easy it's pretty much after you have all your wires uh soldered in your it's just plug and play so it's easy to modify swap out your servo if you want or if you want to have like a different led ring always swap those out because they are made to be um uh modular yeah they're just going over that we do have one that has the three pin already attached but again if you have a servo already line around you want to update that the uh rtbw led rings um the j the plug the plug uh jst plug yeah the silicone covered jumper wires just you know it'll be easier when you sort of uh sort of coiling it up and bending it and then here is what your assembly looks like the uh jumper wire the plugs and the sockets so you'll be able to easily thread this through and then mount it onto your body moving on to the 3d printing all the parts are listed here the only thing you'll need supports on is going to be the front body you know the back body and it's just because these tabs are holding up here and I just list the settings that I'm using for here it's pretty minimal for like the support density uh six percent and then the overhanging um you are gonna have to create custom supports so inside of tira now there is a little support tool that you can use to just place two little boxes on the tabs and that'll be the only uh spot where it'll do the supports the rest of the body has like these giant drafts that uh all catch and same thing with you can't see here but the um the standoff are all drafted like oh yeah very nice they cannot really good yeah let's draft up even the uh top here yeah even the yeah that type of overhang is like okay because it's on the inside it's like that oh you can't see it yeah very nice oh yeah it's all good there okay and I think that's it for support materials we everything there's a fusion file it's uh in the link there yes you can so you got the fusion file load uh whatever format um let's move it on to assembly so you start off with a wiring after your led wire your led ring is wired up you can thread those through like you were saying before and just gonna go through the holes um this is a good order to go in just because of the way that the um cables are on the jst and then the pins on the back of the uh led ring so you're not sort of you know bending them or going crossing them uh over each other so to get a to have them in this placement the frame assembly use the m3 by six millimeter long screws to attach the servo holder to the frame see the angle of how that is here what they want to pay attention to is just the I mean it shouldn't pretty easy since it's only three of them and that's mainly because I can't cover over the screen part right yeah this little part right here will um go on to the screen right here and then just align the motor uh holder soft flat the way it's shown there and then the servo mounts uh from the side and then you can at use that additional space that's there to actually if you have any wires left over you can just coil it up in here and you can use it as a little storage for the access wire nice same before the 20 millimeter long m3 screws three of these guys are going to attach to the memento board and then once that is nice and screwed in you can go ahead and connect your led wire uh led ring wire to the gst socket part of that and this is the main reason here why we are doing this so that we don't have to sort of thread everything through and then solder it yeah it's so modular and this you can disconnect it exactly yeah there's enough room in there for the uh the kind of heft of the uh of the socket jumper wires yeah yeah so it's nice so you can just kind of like push it up and it kind of gets retained up there I can see it there yeah let me see all that have to work with yeah that's great to utilize that that empty that empty space right it ends up being useful save battery on this other robot I left the one of them on all night and had to hurry up to charge it before the show yeah there is built-in charging so you can charge the batteries connected to usbc right after that you simply touch the back and then you can move on to assembling your base here's what that looks like I don't know the name of this horn but it's included with your servo yeah you can reuse that the two wing uh horn two arm horn whatever you want to call it yep so that press fits in here and um depending on the tolerance for your printer it should be like pretty dang tight fit if not you can go inside of the file and there is something in the timeline it's just like the push little um what is it called in the timeline the each little thing for the history you can just that like either negative point two or add to the point two but you definitely don't want it to be wiggly because you will feel it or you will see it so it has to be pretty like tight when you press fit the servo horn into its little position here the magnet um you're gonna have magnets face down into the little cutouts here and that's so they're exposed so you can make contact with the metal surface or another magnet and that's what this guy looks like here using the uh m 2.5 by 6 millimeter long screws to hold that sandwich together and then you just easily align the little teeth up to the shaft and uh that just press fits in there again you can use the uh screw before you um combine the little base plate together to have the horn attached to that permanently yeah i really like this uh when i worked on the adabot robot i had to really be um cautious of how i mounted the servo horn because it has to be in the right spot but something like this like it doesn't matter it it's a circular thing like it doesn't matter where it is as long as it's you know i mean even this one here it's not a circle it's it's really approachable like you don't have to yeah it's really clean and like modular you can it's not destructive you don't have to like like everything all of it after it's installed like it's all really good yeah everything anybody who's like starting this traditionally this would be so much wire and complexity of like having to attach everything yeah like once you wire everything yeah like once you start soldering things together then it's like oh i can't use this you know like for a hero shot say yeah i was able to pretty simple one on the back and you're like here's the memento you know here all the buttons and everything that's accessible to it yeah so it's really really good design and that's pretty much it it has enough weight to be able to be held on to the shoulder with the uh 420 milli amp hour lipo battery i can't speak for if you go higher than that like the 2200 cylindrical or something like that that should work and then just showing here that if you want to go with the tripod attachment here you're going to need support material just on this part right here and then just so that we're not using both of the um the two wing servo horns using the four here and the same deal with this guy you want it to be like the tolerance you want it to be super tight so it's not woodling around mm-hmm same thing with that for uh screws to uh sandwich everything everything together and then the three eighths by quarter 20 screw just fits right on there and it is compatible with uh any tripod very nice that is your assembly all right check out the alarm guide um let's know what you think yeah uh there's more there's code so if you want to get um the code on there you are gonna have to use the uh web serial esp tool super easy to use uh walks through all of these steps to get that to go um i did it all on the mac and it worked just worked okay here's the uf2 for that you download and it's pretty detailed on exactly how to get everything on there what button to push to even get into the um dfu mode definitely read that and then usage um you know what is happening operationally like when you turn on the screen how it's tracking your face and then its behavior you know when once it loses uh your face goes back to position and then some troubleshooting stuff on uh how to get the uh optimal tracking like having good lighting the um the distance of where your face is so all good stuff to keep in mind yep uh he has nice code walkthrough as well so here's uh some of the code if you want to really dive in and start editing stuff here's where all this is cool you gotta paste the text stuff of course all downloadable and check all these out i have no idea what yeah really really great work rent yeah super detailed um and then if you folks are new to arduino this uses he used platform io which is just a way to kind of i guess make make the compile time quicker because there's a lot of code to get um the camera stuff working so the platform io stuff is really good to for arduino users uh they probably know about it but it's cool to you know talk about it still yeah somebody was asking if you could link two of them together that would be so cool huh but they kind of looked at like they're linked here yeah so there's a whole page on using uh myo and setting it up so that it compiles it is so very nice to have this project is made to be modified remixed yeah definitely very well documented so freaking cool amazing it's profound to shoot of course the kids loved it um being able to you know just dress up and take this in the star roads because it looks like you know the already i meant it just looks like it's one of those droids yeah it's begging to be like some modeler that's like super crazy and blender um what's the other one um oh man i'm drawing a blank you know the the solid the no rhino yeah but what's the one the sculpting one um oh you forgot what it's called do you remember yeah no it's the sculpting one that everybody uses anyway there's lots of you know it's like a blank canvas for for uh uh 3d modelers to like add their details and re-release to what you're talking about just don't know the name of it i know i forgot it taipa say does be awesome to see a remix where it uses a high quality webcam uh companion as a camera man on the youtube oh and tyler yes yeah oh tyler oops sorry yeah yep yeah um on freaking cool forward oh that would be awesome to see it doesn't need an sd card okay so frank confirms doesn't need sd card uh d11 is impressed with the length of the empty screws yeah definitely when you'll better to have them and not have them you're gonna need to have them and not need them and not have them you're gonna need that drill your screws are great yeah a drill goes a long way absolutely yeah maya blender knows another one um oh boy what is that i can't believe i don't remember what it's called oh it's great for sculpting um forget what's called z brush z brush um brush that's the one i used it a little bit back in the day and uh it was amazing not the z brush so long great for uh two modelers and then yonny's got just every robot you can think of you know glad is he got uh i forget this new one from uh oh um and or yes and or i forgot his name these little guys yeah that's a good one this one i think is from borderlands this is of course um db1 from uh fallen jedi this is uh is it winston i forget his name from the portal to serious i called it glad is glad this is this one here yeah glad is this one is uh i think winston wilson something like that he's the one with british accent yeah the crazed robot um all right good stuff thanks for that awesome yeah super cool what a great way what a time to be live to have your own 30 or that can do face tracking and throw a little micro servo and all sudden you have a campaign robot that can follow your face so if you want to pick up any of the parts um sign up to get notified when the memento is back in stock camera bots we get to 10 off your order so cool amazing um have a track here yeah we got to send one to jp so you can show it off uh during a unboxing or something we won't say what it is it's not super secret but might as well just a lot of people have already received theirs some sort of box Wheatley thank you so much uh did you dove in Wheatley and um uh does this work yeah Wheatley you want to see a real Wheatley come to life um subscribe to mr vault's youtube channel i've been following his project yeah crazy okay all right prototype are we ready to switch okay um yes birdhouse iot birdhouse we want to feed birds and we want to take a picture of these birds of course they're consent that's the trade off we give them food we get to showcase i don't know what the ethics are on that but that we we talked about this last week one update i did to this project it's still got the same roof it's still got the same enclosure we ditched the injection molded enclosure because we didn't have access to things like the USB port and we needed a way to access the prr sensors so it's not being it's obstructed uh we added a tray um because we we realized that having a big deep dish a person don't want to be digging through it so we have this tray and then we added a perch here so it's a little bit bigger kind of displays out a little bit and an angle and you can still have a nice room for it uh for your for your bird feed um another thing i noticed is um we wanted to angle it down and instead of designing angles into it we're just using uh these injection molded nylon standoffs you can kind of see it there um to angle it down let me see if i can go full screen i must say there we go so hopefully this will get a picture i haven't tested this angled case yet but hopefully we'll get some better shots so over the weekend there's still some bird feed in there uh over the weekend let's put this here we got some photos of uh some birds this one yes so let's take a look at our birds start with picture one so here's some birds they're approaching they're not eating yet so this is one bird this is a second bird this bird probably ate and is like looking around and here are two birds and you can see another bird feeder in the background got another bird this is a chipmunk oh so this is what this picture here the chipmunk that's what inspired me to let's angle the camera down and that's what you do that i looked it but yeah yeah it should work because then well the PIR is gonna be on the top yeah the PR needs to be right aligned with where that's gonna feed and you can't really have the PIR sensor be over this area because this is where this is where you know the board is in the standoff star so you kind of can't obstruct it and there's some header pins that get in the way so this is the closest i can get these two objects so having it tilt down hopefully works better um these photos were taken before i did the tilts and before i did this tray or no i did do the tray it's just i didn't tilt it yet so we'll we'll try over the weekend or tomorrow um it spring is starting to happen here up north east and you can see in the background here that um there's no snow hopefully no rain and uh we'll we'll try to clear this up another edit to the code we want to do is to fix the focus so that the focus is exactly where a bird would be instead of doing autofocus because sometimes um it'll not be you see this bird isn't in focus the background is more in focus so brant if you're listening we we uh we request to lock the focus um i'll ask Liz to if she if she wants to edit it so that we can tell exactly where the focus and we still need to test out where the right focus is so i'm actually going to purchase a bird and put it right up here where it will be and then that way we can kind of get some hero shots indoors of a bird because it's very difficult to get a bird in our house and even to film a bird in action eating they get scared is if they see someone through the window so that's a very difficult thing to do um but at least we have some data here to show what are some oh my god i think i know how to cheat this project and get the birds who will not care that you're staying right there stick it in disney every animal these birds are trained yeah they're trained to uh to to like humans because humans have a good idea dude yeah well i know my assignment now okay bounce it right every project how do i how do i bring this to the disney park yeah i didn't want to like that's where i know every bird or chipmunk or duck is like not gonna give a crap you know eat it out of your hand yeah um so yeah that's uh the recent data that we have on this project um i have an email trigger set up so that whenever it um the mento uh detects the picture it sends it or whenever the trigger detects that a new feed has been published it'll email it to me so that's how i'm able to get these jpeg images um i think they're 800 by 600 but i could set it bigger but this is just for testing so that's uh pretty much what i got going on because different types of birds here and a chipmunk which is very cute i wish i could see the whole chipmunk that'd be so great and if he was in focus here i know we have him up here so you guys got gators and sand cranes and all sorts of different wildlife maybe come up in there um yeah maybe an owl is there an owl here yeah that'd be so crazy the horned owls yeah okay cool yeah Brent agrees he can autofocus right after the detection fires Liz knows how to do that but it takes some time to focus the sensor on the bird may fly away yeah i would just have it fixed to that distance yeah i would just say like just take a picture at this focus bracket don't do that exactly stay at that focus point whatever the value i want to buy a fake bird so that we can just perch it up here and then do some testing on the different brackets because i think it's like one to two fifty five or something that i think jp was saying the different brackets that you can do especially when he was doing the um the focus stacking demos with the time lapse it was like testing all the different values so we'll get we'll get it going we'll get this chipmunk in focus how cool but very fun it's really cool to kind of make a picture and then like work on a project where you're like trying to solve a problem is like how do i get this chipmunk in focus and like keep this chipmunk nice and healthy with all this lovely bird feed let's see and it's like so super fun jdevin is describing all the uh the animals that were captured you got two cardinals one is male oh that's funny yeah i was thinking let's run this through chat gpt so we could tell us what uh oh yeah i saw bird is it because this is a project i was gonna say i just saw the scribes within the image and this would describe you can tell it promptly just tell me what the bird is do your best guess can i brag that uh let's release that the chat gpt via detection before it's available for my glasses like the glasses are able to do that but it's like in beta it's not like not out you have to be like in the beta program yeah yeah there's a caveat but you know it's funny that they can't release this that it's still in beta you know yeah and it's probably doing the exact same thing that listed yeah it's a literally a bird feed that's yeah we mentioned that one sure feed yeah like a bird feed all right so that's that one project um we'll work on that and we'll have a something release in the next so next week we're coming out with a video for just the memento we got our hands on all the features full memento with the back plate in the front led play so we're gonna find a nice video to companion jp's unboxing just to kind of highlight some of the features and we're going to try to get some really cool time lapses um and showcase all the different stuff in the fence the phant the python the circuit python fancy camera app that you know is for the memento so that's next week and then the week after we'll have plenty of time to capture some wildlife with the nice fine tuned in focus animals so that's what we're working on in the back burner i've been working on this project idea let's focus y'all so led noodles we have a new shape for an led noodle this wasn't the original or the the main idea is going to be let's take these 12 volts 600 millimeter long led noodles and use um the neo the the cutie pie bff those those atom boards from cutie pie um let's see if we can power this with the cutie pie the uh the um the art the neo rgb driver and the power bff board to power these 12 volts um leds because these are you know they're they're power hungry this is just a test and we'll get it to an end but that's like the kind of the briefing that's like the intro to this like let's make a project um with those new boards to power a long led noodle strand these led noodle strands only come in this one color right now we'll probably have more colors but again it's long it's 12 volts 600 millimeters long um they're lengthy so i started coming uh seeing a lot of inspiration um on pinterest and instagram of edison you know thomas edison style light bulbs they have these crazy coils so i figured how would i 3d print a coil holder uh so i worked on that i got this 3d printed coil that houses uh you know the the led noodle this is a 300 millimeter noodle it's only three volts so i have a little coin cell battery here and it worked out really cool it's it's springy it's like it really has a boingy boingy effect um it just press fits there's no glue um i started these silicone wires to it just to kind of get the the shape idea so it retains its shape um it's nice and it's like well how did you print this you know it's kind of a difficult thing to print upright like that so i have a video here of me printing it let's see if this will work let's go back here let's go over here let me see if i can do it again there it is so um tree supports in cura slicer tree supports is a uh what it sounds like they're the support material that kind of branches out like a tree and i haven't really used them yet so this was my first print where i kind of wanted to use them so this is uh my um my cruelty um sp sp1 printer uh printing in just regular clear pla so it came out really good um i have a page that i can share this is the support settings i used cura has its own kind of landing page i guess on how how tree supports work um this is what kind of a demo of like what it's supposed to do it looks like a tree these branches that kind of come out and um are supported under the uh the overhang features on your on your model so here's some ideas of it this is what traditional support material looks like it's very much like a zigzag kind of pattern um so i gave it a shot i haven't really needed to use it before but i thought this coil shape would benefit from these perfect organic looking supports and it worked out really well so there's plenty of videos on using tree supports as well but it was relatively new to me so i figured i'd try it out on this coil shape and i'm going to try to do a really long one so i'm going to make this work with this very long 600 millimeter long led noodle so that's kind of the shop talk i guess if you haven't used tree supports yet give it a shot on something like this what was really interesting is um the support material uh came off in one piece and i had to like unwrap it uncoil it and it came out i don't have the photo to share but i showed it to you um it was like just this tree structure and it was like fully intact so that was kind of cool to see that your um your support material is like a form of art in itself it's kind of neat um so yeah um just a test we'll see what what what are their kind of three-dimensional fun shapes we can do uh for led noodles because traditionally i've been doing just flat things you know because it's so easy to just print something flat in the shape but it's cool to see a uh a three-dimensional shape on the lookout yeah i'm beyond the lookout for a cool shape yeah let's just try to come out some cool shapes you know we can see it's just uh kind of slinky kind of shape yeah um coils very fun and there's another uh zero 2032 coin cell battery very nice for these type of projects to test out your noodle and i got them soldered to these uh silicone wires because they're more flexible and again this just press fits you can see it's kind of popping out right there but it has a really nice type fit and uh hopefully oh yeah i forgot to mention these led noodles have a different profile they're differently shaped so they're a lot flatter so i had to kind of update the profile that creates this uh this uh shape i have to kind of tweak it a bit because it's a lot more flatter on this and it's a lot more wider i guess because of the um the current that it has to pass through it's a it's a little bit more thicker let me change my lens real quick so that it's uh a little bit more there you can see how they're just so much thicker so it's only going to bend one way which is this way oh and it's a lot flyer it's only a flat tape or kind of so you see it's nice and thin there and then wide here so that's uh that's the kind of design difference in these um in these noodles so the one that's hooked up to the coin cell is not the 12 exactly yeah this is the 300 and they just have a different um they have a different kind of profile you can see it's more round all the way around and and you can see the wire is like less pronounced i guess it's less thick then here's the uh the 12 volt noodles see they're a lot more thicker because it's passing more current so that's the kind of wait so if it only bends that one way is it going to be able to do the coil shape yeah yeah you can see it coils okay yeah yeah ah gotcha yeah it's just that i have to tweak the profile of this thing because it's no longer round okay yeah yeah you can see how it's it's more round i have to make it like more flat and longer so um i have yet to update that but you know it's stuff in the background that i'm working on super cool yeah so that is the uh the kind of thing and then figuring out like the length uh of your coil to to follow the length of of this noodle it was kind of a challenge too because of the way fusion um does or doesn't do a loft command so it's a little weird and then storing these is another challenge too so bags yeah so that's what a little bit of a shop talk there um a couple different things going on there um new noodles new problems right yeah yeah nice little chat discussion about clear printing clear and getting the most clear translucent shape sure he's got a bit of white air related plouting uh dj then is uh mentioning the the more walls that you have to figure the walls the less clear it's going to be yep this is true so yeah um tithe writes uh thick nozzle yeah so like a 0.6 or a 0.8 millimeter nozzle is definitely gonna come out more translucent than like a 0.4 uh less walls and you're like one or two walls yeah this coil is about one or two walls and i try to make it as thin as possible but still um you know not super thin where like has trouble extruding but i'm impressed with the the just the way that this is like able to flex it's just the nature of the shape and you can kind of see underneath um it looks pretty pretty good especially when you turn it on like the the uh the diffusion is pretty good like yeah i'm also using pet g will help too i think so maybe i haven't tried it but this is regular clear pla from like matter hackers um but can you see the layer lines there it's a little stringy but that's a pretty good salty print for something so thin and you think it'd crush when you do this but it's not it's it's pretty good you can kind of expand it out of it too amazing that it just doesn't crumble in my hands right yeah so whoops there you go anyway go yep so um yeah spring this is mind blowing yeah i didn't expect it to be springy at all figure pla is pretty rigid so yeah yeah the thinner it is you can get a more flexible yeah yeah cool um we got jump into this we've done apps tuesday for community files again um did your devon did a commit you did a pr for um a 2.5 pitch rgb matrix panel so thank you for that he's added that and then um i'm doing some more part requests recently somebody added uh somebody wanted the bno 0 85 stem a qt this guy here it's that i am i am you an inertial measurement unit it's a nine-dof sensor and it's stem a qt so if folks want that in their product or in their projects check it out we got a stl stem file fusion and a jpeg so you can take a look at it um i think what was another one the audio bff was also added nice so that's the um adds uh audio to your qt pie and also an st card which is which is a new part that had to find from a digi key it's it's a molex part um but yeah it's an amplifier add on to your bff sized dev board also added the reverse feather tft where is it this one this is um the esp32 s3 tft feather with the reverse tft it's got those three buttons on the back here and uh yeah folks wanted that one so i added it up there and that is i think all the uh all the parts we have that are new in the cad parts repo so check those out and devon said he added a five millimeter pitch panel as well yep yep we talked about that last week that's also there as well so check those out yeah all those are the updates this week on github uh cad parts key yeah all right community makes yes five minutes left all right we'll run through all right this week community makes is just in time for easter we got this locked gear easter box so it has this cool little gear that locks the whole box let's see it there yeah on the gear's turn and i really like this little indicator up here that shows you when it's long or when it's so cool all right yeah it's a kind of a rack and pinion mechanism yeah check out the inside place i'm going yeah um so i had to do like the tall the horizontal expansion for this is like a negative three so some of the gears that sometimes don't touch oh i tried like point two point two five and it just like you can see right here this one over it's already out of place but that's the only way i could get it to print um without it fusing so i have to like re-level the printer for that right yeah that is very tricky to to design and to 3d print the rainbow filament that i used uh you can see here how it changes from like a blue to a you know purple to a blue yeah the one i did for the time-ups man it was so perfect the way it went from like green to purple on the back but then of course that fused together oh i see let's take a look at it i'm gonna add it to the stage yeah that looks very nice yeah it's green and then like a red brown finally purple it's crazy that it prints with such so much overhang on the the bottom is pretty much the top right right wow kind of see the a little bit of drooping but because it's on the inside you don't really see it of course this is supposed to be made for a bamboo printer so oh yeah the m3 file um with all the colors in there i can just print the single color one oh man this thing is so cool yeah this was uh this is a paid model this is a paid model it's uh been discounted 25 percent yeah yeah two dollars 84 or usd man from 3d tech designs they've been tested gifts looks amazing in multicolor um all the details and stuff so it is multicolor it's not like color swap with the filament no this is multicolor that is a lot of colors right impressive wow yeah we really need to get a bamboo printer when they release their new one and all the other ones are on sale yeah but yeah unfortunately the the way that like cura can't open up the bamboo studio file so i was gonna do at least the dual color one but right it's not there yeah bamboo texture p i play i want the bamboo just just for the speed i don't want to print out here great for your chocolates you know story of chocolate we want chocolate holiday with chocolate is okay with me what's that i said any holiday with chocolate is okay with me and anyway uh check it out designed by 3d tech designs it's a paid model but very cool part and you're fiddling with your uh what do the kids think yes like you can see through into the gears like clog hey did your devon says there's uh there's now a cat parts rss feed and discord so you can always check it out do you always get your update on discord um whenever i do a commit or anyone doesn't commit awesome um yeah kind of feels like an old clock how you can see through it mm-hmm yep knowing how a rack opinion works yep now add pneumatics for power steering right yeah i did a rack opinion a long time ago and um it was fun it was it was like a wacky do you remember the wack opinion let's let's do a quick detour i know we're like one minute but real quick just type in rack and pain there is well just look at the gif and it'll speak for itself there's my rack opinion project you see the googly eyes see that's that's what makes it chef's guess it's a fun project and it just sits on your desk and does that all day long and stares at you moving on to what's the community makes first up we have a raspberry pi five case posted by alex roresh posted up their make of the raspberry pi case it's not fits holds your pie has access to a couple ports looks good thanks for posting that after that we have a remix of the the zelda master sword posted up by um free karate 3d they pretty much remixed the the sword so it has some of the kind of easier to work with leds that don't require a lot of soldering this sounds like a built-in remote which is kind of cool because it's kind of like right on the surface of the of the prop so that's pretty cool nice breakdown here of uh what they did in a little youtube video as well but assembling it so pretty cool i like it and after that we have a because it was a remix no it's just to make uh from thomas thomas uploaded uh their make of the the guardian sword from breath of the wild the zelda video game and um they got it mounted on the wall i think also use different leds because you can see the plug is in there real quick i want to highlight through this comment this was really hard to do yes it can be absolutely um it's too small to fit on their printer it was awesome sun loves it did not install a battery hooked it up to use to be charged oh okay and did not use the price of new pixels great great model thanks a lot for sharing this yeah that's why they're there definitely uh use what you got looks really cool and that is this community's make i kind of rush through them sorry i apologize but we're kind of low on time it's only three of them yeah it's only three of them but uh there we go we do it when uh link movie comes out yeah maybe be forced yeah or a new video game yeah we just need to get away from the the trinket hmm yeah unless there's a prop maker trinket interesting how do you fit all that just yeah i know maybe it's you know the feather is just the right size and uh battery charging everything you need all right well you guys got an idea of what we got next week and the week following um thank you everybody so much for tuning in supporting Adafruit don't forget the scoop on code is good for the next 24 hours camera bot memento's out of stock but you can sign up to get notified when they're back taiz said there are eight a box subscriptions have opened up link link oh okay you uh the only way to get the memento and the uh wait no sounds like i'm spoiling it yeah thank you if you want to see what the secret stuff product are in the eight a box you can i guess sign up nice so um go eight a box calm and sign up if you aren't a subscriber yet we're planning to have a couple more this year and uh yeah we'll see what's uh what's happening it's a great way to get uh guaranteed new hot stuff yeah check out real quick in the discord he did have him posted his remix with memento case you got some cool oh yeah that's really cool that freaking cool is that that's dope yeah i like all the indentations and everything yeah very nice nice and smoothed out yeah i'll let me print it out too if you get the files up there hmm i like the uh the shutter button there yeah looks good cool maybe see um you maybe that'd be cool yeah spring break so uh no show next week not doing the show next week we'll release the memento features video uh project though that'll come out next week but um no show next week because i'll yeah i forgot yeah yeah yeah it'll be hard to put the full house kids yeah okay well we'll be back uh in the next two weeks then and then uh tonight so again thank you everybody for watching we'll see uh next time but uh tonight we have um two shows starting with show and tell we invite you to come on show and tell you can join the aid of your discord and get an invite link shortly before the show so you can share your projects um it's tonight at 7 30 p.m eastern time and then shortly after follows ask an engineer at 8 p.m eastern time full hour of open source hardware news new products on npi and more uh i'm not sure if jp's having a workshop but normally jp john park does a workshop show live stream every when you can on on thursdays fridays are either tim foamy guy or scott shockroft doing deep dives in circuit python fridays at 2 p.m pacific or 5 p.m eastern get a full list of shows on discord by using uh showtime question mark showtime thank you everybody we'll see you tonight we'll try to make it on show and tell but uh sometimes things come up oh my god yeah last week my kid fell and broke his hand and chips too yeah he's recovering though he's his first time it's fine well i guess the second time now huh breaking a bone yeah remember when he fell on the playground and then the other one runs into a wall and then yeah it's into the side of the table that's why we're not doing a show next week you gotta you gotta really watch these kids thanks everybody so much we'll have another coupon cone tonight we won't see you next week but the week following with some more fun show stuff thanks everybody we'll see you remember to make make a great week after
