And if you know, we've seen some 3d projects. She's been an integral part of 3d Hangouts doing all just about all the code for our project. So everybody welcome her to the team and it's super exciting to have her do a lot of new product guides helping Kat me out helping Lamar out and just being overall awesome. So shout out to Liz helping out Lamar. Big time with all of the new product guides doing that. I think she's doing the pretty pins as well. Oh, cool. A bunch of the breakouts that like the guides for all the new products that come out like showing all the pinouts and showing how to do a factory set and all that stuff. So definitely huge shout out for a mental help that's going to come into Lamar. More musical projects to come as well. And reminder that Adafruit is a real job. And they're real people. Hopefully this year we'll be able to do something like this. We're all going to get together again. So let's all work hard to get there. All right folks. Super awesome. All right. We I think we're ready for this week's project. Right. Go ahead and jump right into this week's project. We got some rocket shoes. So a couple of weeks ago, Phil be or Phil Trone PT saw these awesome shoes that came out from Nike. Andrew Stink did a really good review on the 3d printing heels that these shoes come with. I did not bring the ones that these actually come with because they were actually like injection molded not 3d printed. No, it's fine. I mean they kind of look like this without they look like this without the rocket little things on it. But the whole purpose of it was of course being at Adafruit, adding some LEDs and some motion activated, you know, animations to having them be like wearables. So one of the cool things about these is the platform that they're using. I again know nothing about shoes. So these are the what's the name of them? They're called laser low. Yeah. So I guess it's like a it's a collab with acronym. So Nike acronym. Yeah. So the way I'm seeing it just from that is that the Nike hands out like, you know, a platform of shoe that other third party companies can design on top of. And one of the things that acronym came up with was having these heels that you can have like a three printed attachment for them. These are if you could close the blind there actually. Let me do this change. So we just do that. Oh, here you go. It's on this little branding of the acronym logo there. And they have they do like I know they're like designers that do like clothes and as well as the shoes. So the heels that come with this shoe, definitely not three printed. These are injection mold. You can see how thick they are for the injection. Yeah, they kind of they're going to match the style of the shoe. There's like three or four different color choices you can get. You can purchase them from different distributors. We were able to get ours from acronym themselves. They still have a couple of the sizes available. We have the link to the learn guides. You can get them if you'd like. They come in different sizes. I did not mess up the shoes. This is how they came. That's like design. It's a little design that they have to kind of flare it out. So they kind of have these this kind of textured cutouts, which is kind of interesting. But yeah, so you get what three bolts here that has heat inserts. And that's how you tanch them. These screws came with the with the shoes themselves. They're kind of like flathead screws and three. I love them three. That's great. Shout out to thank you for doing the metric screws and not imperial for that definitely helped a lot that that was standardized metric, but huge fan of them three. Instead of having to use a screwdriver, we got these really rad thumb thumb screws. We got these hunk and thumb screws are out of my anodized aluminum. So you can get them in different colors and get these on Amazon. But yeah, they're really nice for kind of take this out. Oh, yeah. Yeah. So it's really easy to take him out. But what was kind of interesting is you actually don't really need the screws because the heat sets themselves are kind of extruded out a little bit. They kind of protrude. So they're able to kind of fit the the print over it. So it's interesting as you use PLA instead of having to use like a ninja flies. Ninja flies can be really difficult to print. I did try the the more rigid, not as flexible and then to flex the semi flex, but that was still yeah, it was still too flexible for this. Like the armadillo, I think it's what it's called the 70 70 shore hardness for that. Sure. So the goal was to like, all right, let me recreate this and then add some holder for the circuit playground. So instead of kind of creating a custom circuit player on case, we figured to use the polycarbonate clear case that we already have injection molded because it's got a lot of protection to the board. And it has on board buttons that you can press switched, you can access as well and all the ports are available. So you can do you can connect alligator clips to any of these pads. Do you want to do other stuff? And really the the idea to use the alligator clips is kind of like a make it modular, but also just it's easier to kind of assemble it this way. So that was kind of a cool thing in it kind of adds to the aesthetic that this is like kind of like your Doc Brown sort of invention where the wires are kind of out there and exposed a little bit, but it kind of adds to it. Yeah, the exposed wires definitely adds to the look that they're trying to do with the ones that they included, which a lot of the artists did have the ability to go in there and create their own so they could showcase that. Unfortunately, some of the designs that you've seen in Andrew's video, they don't really fit at all. It looks like they were sort of rushed to get this out. Yeah. So this one did fit. However, this was able to fit because the shoe this is a nine and a half. I guess some of the other bigger shoes maybe this didn't fit. So that's kind of why you kind of recreate it because you made it parametric and scalable so you can easily massage and move some of the sketches around if you want to change up the geometry. Yeah, we'll jump into the fusion file in a little bit to take a look at it. But yeah, one of the things I wanted to avoid was having it be so thick because of course you don't need to have it be that thick for what you're needing here, which is just a bunch of mounts for having like the little rocket boosters, which of course you can go ahead and it doesn't have to be a rocket booster. You could take the existing mounts and just model something else. Yeah, you have your battery mounted on the top here on the back here and you can see how it's nice protected between these two. Yeah, I'll do a Yeah, so you have the extension that JC extension on there and the way that this is even held on there to is a bunch of the tripod adapters. So you have a 20 to quarter 20 to quarter 20. It's attaching our very lovely polycarbonate acrylic case that Mike Dole has designed and these have the tripod screws adapters to attach it to things. And then we're using the three fourths of quarter 20 for mounting that on there and everything's attached with a bunch of M two and a half, 2.5 millimeter screws, completely modular. You can take it all apart. Like you said before, one of the difficulties in building something like this is having to thread the wires through to get the boosters on there. You want to make sure that you're not playing that threading game where you are having to solder your circuit board and then having to unsolder it if you need to change out your part. So to avoid that, I'm going to get some slack in here from that. You can see that the neopixels here are attached with some some jumpers and jumpers so that can easily detach. One of the things you have to think about when you're building the assembly for this, you want to make sure that because you're still prototyping as you're printing, you want to make sure that you're not playing that game where you have to unsolder your wires to thread everything through. Not really good use of time. So definitely always think about having all of your circuits being able to be disassembled in this way because in this game, so go ahead and show how the entire thing comes apart. Not I've taken that out. I need to actually release some more of the slack to get in there. It's so fun to take it apart. Yeah, another thing too. Another thing that Nike really didn't probably for cost savings that they were including these, I don't want to trash talk, but yeah these screws that were already starting to rust. I mean these thumb screws weren't that much money so definitely would have been a much more easier route to go and to promote it that way. So you can see here how it's routed here. We just have the male jumpers on the other side that's connecting to the little females on this side and we're using very lovely PCB Neopixels. So you have the resistor everything on there that you need to get this powered up and yeah this just goes through here like that and then you have a couple of other mounting opportunities and these areas around here if you want to go ahead and modify this as any way. So what I really like is that when you designed the clip and the boosters it could have been a like single part kind of like how this one was but to optimize it for 3D printing it's really smart to kind of chop the pieces off and reorient them on the bed and kind of optimize it so that it prints you know without with as least support material. This looks beautiful but you're going to need the type of supports that I'm using on there's breakaway or you can use you can also use like PVA because with regular supports you're not going to get this super clean bottom. There's a special filament called breakaway filament from Ultimaker. I don't know if anyone else makes it. It's a special filament that's designed to be support material and it prints beautifully. A couple years ago we did like a little thing about it but this you can see that this is the bottom layer. This is where you can kind of see a little bit of blemish there where the breakaway support is. So if you ever thought about like more support material try it try some breakaway stuff it's only I think for Ultimakers and I've not seen anyone else. I don't know what the the material is but beyond that you're gonna need like a dual extrusion printer and the way that the so that's cool and that's a really good method to kind of get a phenomenal you know part that has support material without having to go the SLA route. So that was a really cool option or you can go without you know optimize it even more to chop the booster off and optimize it to print kind of upright and then angle it so that you don't need any supports for these tabs is really clever. Even in the model itself you can see that I'm using fillets all over. Oh only filleting where it's on the top so that when you're yeah that's cool. So your support you don't need any supports in any of this. Even the top here you can see I have all these fillets on the mounting points so none of this actually needs supports except the heel and if we jump into cura yeah we'll jump in the cura and let's take a look here. So inside cura here you can see how the support materials are set up. Ignore the one for the booster like I was saying earlier. Oh that's just yeah that's just so I can get all of the parts in here. Everything comes nicely oriented for you so it's nice and flat ready to go. All you have to do is turn on your supports. The only thing that you really need to look at for this is making sure that it's the placement is everywhere and that your support angle is at 40 instead of 45 for whatever reason cura tries to add like chop up the way the supports are laid out if it's at 45 not very good so that's one thing too you want to look out for that your support materials aren't like scattered all over the place or you have these teeny tiny little support pieces that you don't need like this is actually an example of a good one right here where you don't really need this but trying to it's a little finicky trying to get rid of that you can add like a support blocker on there too but yeah don't need it other than the heel part and that's why so the support density is also an important note to look at instead of something default like 10 drop down I think it's usually 20% yeah you don't need that much you don't need 10 sometimes the high what I call high support density is like 6% and the other thing too to look at and we've talked about this several times before support line with for supports they don't need to be 0.4 they don't need to be so fat why do they need to be so fat you want them to be thin and you want them to be easy to like flick off with your finger while still being steady enough to support the material that you're printing on top of it so a thin extrusion for just the support material that's cool another thing I was looking at was you have support brim enabled and that's going to help that thin I did not use it for this one but you can just in case if you have some adhesion problems with your bed didn't need it on doesn't have adhesion I would with your bed I would definitely use it if if you have problems with that using the texture PEI for this one so it was able to hold on pretty well okay the other thing I think we always talk about to the support z distance I have it at 0.21 and that's just so that's not fusing the supports and the main geometry together what's the other broken record setting that I always use support interface layer so you don't need that yeah I don't need it uh sometimes you need it sometimes you don't yeah I guess the underlying layer right the overhang doesn't really look bad here there's nothing really to look at jump over the overhead looking at the underside where the supports are how thick is this uh this right that's two millimeters two millimeters thick so you get a little bit of flex there and that kind of helps you kind of hug the heel of the foot well when you walk you definitely are bending your heel in like all these different ways you don't realize until you have like a three-print part on your shoe cool so it is flat you have a flat surface that it prints on right mm-hmm okay yeah so I did or I these are already oriented ready to go yeah that should be uh you just turn on your supports and get that printing again just for the heel for the sports everything else uh even the um get rid of this you can see the battery pack you take a look at the way that the mounts are for that too I have a chamfer right on the bottom there and then right at the top you just have fillets everywhere to make sure that it's nice and strong yeah so always try to keep in mind the way you're designing things it's like yo Kira I don't know why you're telling me this is red it catches it just fine yeah I think there's some setting in the in the background that you can change to only look at only highlight uh overhangs over a certain angle I forgot it is but there's a way to do that yeah but this catches it just fine uh with the the amount of fillets in the way that it's uh drafted inside of fusion that's a cool thing as the boosters are symmetrical so you can just print one or print it print it twice same thing with the heel yeah some of the designs that uh Nike had oh the heel is symmetrical as well that's great yeah the heels for one that's one of the things I wanted to avoid to make sure that you don't need a left you don't need a right um same thing with the booster uh the booster uh yeah we already showed that it just twists right off so we're using the threading inside of that to get that going cool and I thought I had of course when I'm live on tv is one of the uh it stops the why come on let me rotate fusion there you go oh my god oh it's because of the trackpad again I'm trying to use the this was just working like beautifully yeah I swear I know how to use it well any manner we can uh there we go yay yeah I don't know how you do that with your trackpad well what was I coming in here to show uh I think just the the geometry of a bunch of fillets everywhere to make everything nice and strong like here is this will pop right off if you don't fillets all over the place just to have that nice smoothness all over while adding the strength rigidity that you're gonna need for something that you're wearing on your feet yeah oh um let's see so the sketches if you want to download the files you have all the sketches here so if you need to uh not to make the booster bigger or you need to change your threading for like tolerances on your printer or if you want to get down to just having the the heel for a different sized foot because this is uh design it should fit like the nine and a half up to ten and a half uh but uh in Andrew's video he was showing that the sizes that he downloaded for his foot now the 12 size 12 size 12 did not fit his shoe so if you want to uh he ended up uh scanning the heel clip that was included with the the pair of shoes scan that clean it up bring it in diffusion and then you can reference the holes there and kind of redraw it and this is what i'm showing off here the um the screw amounts for all this you can just move this around if you need to have like a bigger shoe or a smaller shoe which um you would have figured that um design wise if the shoe if the shoe is bigger that it would just be updating from here you know but unfortunately now it looks like the entire shoe is being updated like scaled like that instead of being smart and doing it this way yeah i don't know i've never designed a shoe uh yeah i'm sure there was some other design constraints or something cool so folks um can modify the sketches and modify the sketches you can modify all the cuts so if you want like a different shape for it although keep in mind that you do have to stay within this um the shape here okay yeah so you kind of sketch that out there so you have a good profile to look at yeah and uh look do i have another one over here it's already assembled can i get two shoes yeah and then of course uh i think the cool thing for like the um the way that it was coded is in make code and we'll go over that so the action is if you stomp hard which in make code you have like different um g settings like g4 settings and i think it's at eight g's so when you stomp really hard instead of just walking you'll have that little animation where both the boosters turn red the central one does a little red ring and then does the little um sparkle and i think you can hear it there it does a little pew pew and then because of you know just how easy make code is to quickly iterate get things over you're able to do like a if you fall down you have like a little fall attack or if you're on a swing and you really go vertical you can i don't think anybody around is going to be able to hear that distress in a way you know swing up but yeah you do have like a uh you can add like different like if the face tilts up or down you can have like different um orientation orientation animations for your orientation and of course you can edit the the way that it blinks and all that you can tell how many milliseconds you wanted to do or if you want to blink a different color uh let's go ahead and jump into the guide all right let's take a look there okay i'm gonna go over the parts all right yeah so some of the parts here that we're gonna need uh the a lot of this stuff is in stock the uh circuit playground express if you get the uh 4h version those are in stock and there's no difference it's just one that's branded for uh the 4h program that is a good reason i get that one yeah a nice green color there and you got the 4h logo and then the uh 428 milli amp hour battery i do have a i do have a uh case that for the 500 milli amp hour one because that's what i started off with but notice that they were all out of stock right so i switched over to that one and then if you want to be able to charge your lipo battery we have the uh micro lipo charger here cool recommend the usbc obviously and then the alligator clips definitely want to have those um so you can you know like the small versions yeah there's some bigger versions but these work well with the 3rd figure yeah supposed to sense the the size constraint they're gonna have on your heel cool the mini button pcb new pixels yeah pack of five we love tripod stuff that's what we stock different tripod adapter screws so you see here we need two of them one for the uh the kind of the female socket one that's kind of the male connector here that plugs two quarter twenties together yeah cool and that is what's on the back of the polycarbonate circuit playground express enclosure yeah that's great it's like heat pressed in there of course you're gonna need the nike acronym blazer lows hopefully they are in stock in your size and the m3 thump the thumb screws thump thump yeah they have like red and blue and purple and black yeah looks super cool the uh m2.5 by five millimeter long screws to attach the boosters recommend metal screws folks because the nylon ones might get i tried i tried i really try to use all the like the stuff that we have in the shop yeah the screws aren't passed through right they don't pass through they have to bite through so you have to create the thread yeah so just keep that in mind um that that makes it just much more stronger you want your boosters to fall off mid-flight yeah cool and then the uh m2 eight millimeter long screws oh i'm sorry those are for the boosters the other ones are for attaching the uh the heels and the mount for the battery in the strict playground express okay cool jumping over the the circuit circuit diagram it is not found give me a sec folks let me see i can make sure yeah it wasn't published let's see give us a second folks published there we go all right jump back in we're flying building the airplane as we're flying what is the thing that one's not public what happened i did this at night and it told me it was published liar all right continue there you go circuit diagram where were we where's the circuit diagram circuit diagram here we go anyway this is why we do this all right jump into the circuit diagram you can see how everything is hooked up pretty simple in terms of the view of the circuit diagram how everything is laid out but the actual soldering and making of the circuit to this build yeah it folks could fashion their own method if they kind of want to do it differently but this circuit diagram should give you an idea of that you're just sharing data ground exactly between the two pixels you can create a y connector like pager has or you can use some sort of bus um like a little a little power bus thing where you can solder into that screw that's big though that's giant it's dependent on your bill yeah if you click on the photos you can enlarge them any of the photos in the learning guide and you click on them it'll show you several different sizes let's see the original size here what i'm doing here is just creating a white cable like you said i'm just sharing the um v out the uh the digital in and the ground i'm splitting that into two additional connections and then having the those be rewire reconnected with a the male and the female connections there the jumpers yeah right of course easier said than done you have to have like all these yeah third helping hands to hold it dinner friendly project did we i think i did uh i didn't in the video so yeah uh just it's definitely a really good very careful is it it's easy to you know we made it it's all right moving on to the main code you can edit this and have your browser well not any browser i'm sorry only in chrome has that usb extension there built in so you can connect to your zika playground that way or you can just go ahead and download a uf2 whoops okay i didn't catch that one cool all right you can see where that code came from right let's see so what's cool about maycode is you can either edit the maycode like file or you can just drag and drop the uf2 file which will get you just going real quick all right it's really nice with the with the boot loader on the circuit playground you can switch between circuit python make code and arduino with the the reset button so it's really easy to kind of switch between them but you've offered the the uf2 so you can just drag and drop it or you can edit the the code and make code so i'll go ahead and open that this opens it in a new kind of instance make code has like a special embedded code thingy where you can play around with it you can hit edit that'll bring you into the editor and i really love that you don't need any logins you know your account it's just saving on your local uh like caching or something there is this thing called uh dom do you know whatever the programming web thing is so um this is like some advanced multi-threading code here going on so on start you're setting up the strip the external strip on the circuit playground you have to connect to a1 so you can easily change just whatever pin you'd like yeah there's only two pixels and that's how you set up an external strip uh since these are being shared it you can probably just have one pixel but you can have two it doesn't matter oh that's right yeah it should only be one it should only be one but the two works it doesn't matter you can do inputs so here in the input block you can see all the different inputs that you can do so like on 8g this is where you so that's the sensitivity so if you wanted to shake it you could do that but the 8g is like it's only going to look for hard hitting things exactly so that's what you wanted there yeah because you don't want to kill the battery just keep walking around having that go off so on the a g you're gonna uh and i've tried many uh arranging of the blocks and this is what played like back uh favorably so having the pew pew sound play first stop any animation that's going on and running in parallel you're going to have the strip show that little fire animation in which of course you can change around the amount of time you can show that on on the strip and then on the um to the playground board itself yeah then immediately after that you're going to do the little sparkle you're going to do the same thing on the um strip and then you're going to clear it because you don't want it to just stay without it actually animating so you got to be very specific on telling you what to do for each step yeah each stage of your animation cool then when you click the a button you can have a different animation and play a new animation of laughter looks like i think it's supposed to be the strip might have been uh left over and so it works yeah it so works while a button was pressed do you show animation so that's if you want like yet another animation happening so oh it's almost like a demo mode like hey let me just kick start any animation by pressing the button exactly cool and then here's your your uh your oops i fell detection face down stop all the animations and do another run in parallel and play melody yes and there is i think in so you i don't remember i did not build this they had like um candid ones ready to go did they get rid of it yeah there it is gallery if you go in the gallery you can um check out ones and edit those which again you know this is so cool that the you know block editor allows you to quickly go in there and do a little you know little tone what i have without having to sit there okay this is uh this is c this is d a e and you know trying to figure that out in your head it's a lot easier to have a visual uh and your iteration hearing it on the circuit playground to see okay this sounds good or does not sound good okay cool so you can have lots of fun in make code and just kind of play around with it you think it's really cool like i say in the video educational settings workshops like this is really fun and if you're just getting started you're more of a visual learner i think uh make code is still a really great option it's free right so just make code dot eight three dot com yep it also works with other um cmd chipsets i think so other hardware too uh microbit and uh i think a feather maybe a cricket yeah cool do you just like it now just make sure the links are going and they are not sorry moving on a second to catch any questions or anything nothing so far that's why i'm continuing all right here we go moving on to the 3d printing we already covered a little bit about that but you can get the file maker oh yeah there's another explanation explanation if you want even more and how to set it up how to get it going well it's got like a breadboard if you want to this is make code maker so this is like a different one which is actually run sensors and leds yeah it's very similar it's just it works with other boards other than the circuit player and express excellent all right on to 3d printing already a lot of that you can download or edit the design there's a fusion 360 model you can download separate um formats if you need something else there's a lot to choose from and then the step file is sort of a universal solid modeling thing that you can load in other programs like blender my uh rhino what have you that should work too on to assembly assembly we kind of covered this to uh going over the wires how to set that up everything's broken out and then i'm moving on to threading everything through i feel like we've already covered all of this in the beginning how you want to have your new pixels so you can plug those in so definitely follow it that way yeah um any just pull out any notes or one of the most important things right here that we can't see unless we're showing the picture off is this little washer for the um coritonia adapter because without it it can go all the way through and push out your your board it can just pop open the um the polycarbonate case yeah so this is sort of like a end stop for it so you can't uh turn it anymore yeah like push out the board yes the uh the screw thread is just too tall and it works for certain things but for this one you just print your own thing i would print this anytime you're using it because it has the coritonia that we're assuming that you're going to use it with a tripod adapter um you definitely want to have this washer for more use than just this just so you're not um punching your board through the case that's just the thread is too long okay uh moving on beyond that attaching the mount to the uh heel like we were saying before we're using the uh 2.5 by 5 million long screws to attach to that behind does the battery fit loosely in there uh no so the good good point for bringing that up no so it does have a little bit of a loose yeah but i did add oh you had a little shimmy yeah so we're using these um the capton tape the little strip of the capton side just to increase the tolerance there's a friction do you need tiny bit friction yeah because trying to get that right with your um with your model you're always going to get it either too tight to um this is loose this is a great solution the bad solution from experience mounting tack because like if you leave it in there two years later you're like why is it dries out it's it starts cracking and it leaves the stain so beyond the little because what is it like 0.2 or 0.1 uh maybe a bit of a stick yeah the other thing you can do to see these flaps on here you can actually uh flare mount just a little bit so that you increase the tolerance yeah but i think this is the most safest thing just having the capton tape on there just to increase the tolerance just a little bit put that in there go and that's enough too so it's not rat you know rattling in there while you're walking i did have that problem without before i've added the um that tolerant adjuster cool calling it good tip let's see yeah once you got your uh your battery installed you can use the alligator clips yeah just connect them up and if for whatever reason like um there's some tolerance issues or something or the screws are different or you mounted it wrong um you can notice here that one of these uh the jst port is pointing up and one of them is pointing down so if you need to adjust where the most convenient part for adding your alligator clip in uh you want to make code and update like the instead of a one yeah maybe it's eight maybe it fits better than a two just draw so you can always do that as well if you have to attach to a different pin just because like you know say this what is this this is a one say if like the i twisted it and it was all the way up here well that doesn't make sense for the alligator clip to be hanging out over here yeah so you can update what pin that it's actually connecting to yeah that's in my way for a cable length and placement exactly all right i'm adding it to the studio and a quick demo on how you add it back to the shoe here you want to have your tongue open or yeah so this little bit right here it's like this cool kind of snap yeah so for the original clip this actually goes three here like that hugs in but that's where battery is so we can't do that yeah so um yeah i just want to uh minute or never your cabling so it's like all nice and hidden like that and then you align these guys up so and then you definitely hopes to uh sort of squeeze the heel and it snaps right in like that go even attach your uh thumb screws jay thumb screws yeah definitely should have been included that's no much like you got this great sticker yeah so what ideas do you guys have for adding some custom mounted heels i think one of the funny ones that jp had said was having which they do have one of the artists did have one where it goes down to the heel so you can have like a different pattern so you can have like stomp out like some logos or something or the thing that jp said was so the feet are like backwards so it looks like you're like walking all crazy so that's definitely a really good funny one that you can do and other than that yeah this was really um i think the thinking for pt was to have um just celebrated so more companies are able to add like mounts pretty shoes so 2012 but it's really cool to see someone like nike come out with a nice pair that's not all 3d printed but like four 3d printed that's what i was gonna bring up so i'm seeing like a lot of other designer folks and makers on instagram posting a lot of fun kind of remixes and different shoe clips well i want to see ones that actually work that actually get printed out because some of the the ones that they're showcasing the ones that pt wanted was like this crazy dragon one like it's so impossible to print on a i don't think these are supposed to be like worn they're like artistic uh platforms yeah that's that's cool too but it'd be awesome to you know actually wear them out oh so yeah definitely yeah more useful ones that aren't gonna fall apart that aren't as artistic they don't have like all these tiny little bits and bops that are actually gonna poke you as you're walking okay yeah so for cosplay things maybe that's a good idea so yeah nice uh hopefully encouragement for other uh or even for nike to have more um shoe two styles styles that'll have because it's so easy the if you check out uh andrew's video it looks like it's just glued on uh with the threads the threads inserted in there so it couldn't be that difficult to come up with a mounting uh some a way to mount onto some other type of shoe especially if it's just glued on and that's it how do they feel when you wear them uh not bad like not as comfortable as like other shoes but they don't hurt my feet that was the main thing yeah sweet blazer loads yay super cool i shall be wearing these out as you can tell i have not worn these outside indoors only all right sweet that is this week's project all right don't forget to check out the learn guy if you want to pick up a pair you get the circuit playground 4h it's in stock maybe the case or any other bits and bobs that you might need rock it off rock it off and all right let's go ahead and jump into those weeks what are we prototyping all right um we're doing the chaos emerald okay cool all right for prototyping this week we have some more chaos emeralds these are 3d printed emeralds that have embedded new pixel leds via a circuit playground so i made three different shapes three different sizes rather because i thought it'd be fun to have this model be printed in different you know smaller printers bigger printers so we got a big large medium right wait small medium and large so you you might have seen this one last week it's it's really nice it's got a circuit pretty embedded inside this one does as well pretty similar we have a 3d printed bracket that allows the circuit player on the snap fit so that's really cool without any hardware you can snap fit this but then you do need some hardware to attach the the snap fit case to this like extra bracket and with i came with this method of adding built-in standoffs uh to the lower half of the of the of the chaos emerald that way you have like a really secure mounting point to attach this kind of it's kind of bracket here another cool thing is i have the snap fit grabbers on two of the sides and then just these lips here on these sides that way you can kind of do a little bit of this to easily open it and close it just flexes slightly the lower half here is just kind of printed in this um every white trans translucent white pl a which uh diffuses nice very nicely there are little nubbins on two of these sides that that catch the grabbers and just line them up and it's easy enough to snap them in there you get a little bit of a seam but not too bad and that's kind of what it looks like here so you got a nice hot spot here but you're able to kind of illuminate the top here too just because of the nature of the filament and uh in different lighting situations it looks more brighter than others but yeah very very happy with this one so that's the medium size one this one is the smallest version i can come up with so this will fit on any of the small 3d printers same dealie here you just squeeze it to open it you can see here i got those same grabbers on the on the edges there and these lip stoppers here on the opposite ends this is a circuit plate on blue fruit because i wanted to try out some uh some bluetooth connectivity i forget to mention but the battery is like um in between the the bottom of the snap fit case in the bottom of the pcb it's just in there it's like a 500 milliamp lipo battery you could also use 320 or 420 whichever one of those but with this one the the standoffs are built in i forgot that this is the blue fruit one this the standoffs are built into this one so you just have the snap fit case like screw right into the the built-in standoffs there i only added two of them because i didn't need to have all four of them while you're on the subject of the screws jeblero quick is asking best way to have the um your part except screws is it give up and use a cap of nut yeah wants to do a project where he does not require the inserts yeah sure uh so so let's say you're doing an m3 hole i would make it 2.8 millimeters in diameter that way you have it's a little bit tighter and then what i like to do is i have an m3 screw tap and i will i will create the threads into the standoffs by just slightly kind of you know driving into your standoff that way yours a little bit of mature that you're going to bite into when you're when you're threading it and that way you can have the threads easily or the screw threads go easily into the standoffs but if you're using a cap nut you know that's i don't have the real estate to do that here so that's why i'm like i'm just going to go directly into the screw the one you use here uh that's an m35 so just an m3 um yeah so that would be my suggestion and then like say uh this tab here i would make this hole 3.2 millimeters a little bit bigger because i actually don't need the screw to bite into this piece i only need it to bite into this guy here so that kind of makes a little bit easier too i believe this is the set we use that's a good set yeah you can pick up an m a metric set of screw taps and those are great get a get a handle as well a little handle for your screw tap some of them come with it some of them don't but yeah that's a that's a great question i should really do a like a tutorial on like why you would go with a screw cap or and look at different projects that i've done to say like here's why i screwed it this way here's why it has an insert because i'm going to reuse it um super great question cool then uh vince is asking could uh neodymium magnets work here instead yeah you know what neodymium acts would work pretty well because i mean just be able to take this whole thing off yeah for sure and there are so many different neodymium magnet um diameters thicknesses that you could totally do that um why didn't i do it oh you did it in this other project yeah i did in the other project the cube that we're working on but i don't know i think it was uh it depends on like if you have the magnets you got to worry about the tolerances of the magnets all the magnets we have we gotta use it for a different project then you'll have to like and you glue them in then you have to that is the most annoying part that's why i kind of stay away from magnets but same thing with the inserts same thing with the inserts too yeah especially when you're still prototyping you're like oh no i need to salvage these and you're sitting there breaking apart your your model for that yeah um but magnets is a good idea too for sure it just depends on uh what you have on hand and what you want to do with it um but yeah magnets would be cool i also thought like a screw thing would work too but i didn't really need to do that i think it's not if it's fun one of the things about uh the the the shape though you'll notice that like you're getting a really hot spot this is because the LEDs are so close to approximately to them um so like the more space you have the more diffusion you get and that's why this one here looks so good because like there's just so much space around the neopixels that the light can just scatter and just kind of illuminate the whole thing but the only thing that sucks about this is you need a big printer to print it um so that's supposed to you know i want everybody to enjoy these these lovely snap fit gem diamonds chaos crystals whatever you want to call them they can be whatever color you want to so very fun and that's what we're prototyping more glowy goodness tights is asking manic on the mac subject of the magnets does it affect the wifi reception oh that's a good question i don't know and then uh yep tolerances sometimes give me grief yes especially if you have something of a known tolerance that works with whatever you're trying to fit yeah and then you have to print it vertically it completely changes yeah so you have to have like a whole new model especially when you're like making these like little widgets to make sure that you can reuse for other projects yeah always gets you and then if you print it like say it's uh facing up or facing down now it's like completely different because you have to have like um supports on it completely changes cool all right i think that is this week's what are we prototyping yeah yeah real quick with your shop talk oh yeah um yeah we got a there yeah we got a nice like walkthrough of some of the tips the that you might find helpful in uh designing a snap fit case so uh this week it was a it was a video on just sketch the etch a sketch case and some things to be aware of when you're designing a case particularly for the tft feather wing and a feather there's just some things about the mounting holes and the display bezel and things like that so check it out it's just a nice little walkthrough of uh some of the things i learned i got the link it's applicable to you know all folks too it's not just particularly to fusion just like design notes okay i got the this week's community make we got some time lapses every tuesday we publish a time lapse video on some cool designs from the community this week we got something from david makes stuff this is a oh this is an excellent fruit bowl with a sweet vernoi pattern this thing is so cool yeah these these these shapes look so cool when they're growing they look like they're growing all right definitely check out uh his profile there is a bunch of these vernoi yeah we'll take a look looking patterns this one caught my eye i forget who i saw printing this out i was like that looks so cool i'm like the shape of it and obviously a good little way to have your fruits displayed especially if your child is always begging for more apples or oranges it's fairly large um no supports and awesome time lapse a little bit of a clean up there just because of the way that the head moves over for the time lapse and uh yeah here it is it holds a crystal i'm a real diamond yeah with the shadows you can totally see like the layer lines for that but otherwise adds some texture to it i like their lines nice and strong like yeah those are really good like uh the sediments and i think there's also like uh um like a thing that you could put inside here so um objects can drop through yeah so you can definitely have that printed out as well let me check out the um his profile page yep let me go to the thing over his page all right so this is dave make stuff this is his profile see he's got some great photos of if you're talking about yeah print that out as well no supports needed right okay and supports shout out to dave it's a free download so you folks can just print it out this is like is this scalable you can probably scale it you should be able to scale it yeah bigger one okay and uh yeah it does some fantastic things he's got a whole t-set i think he's the one who uh was being posted about yeah for the shoes gives out a really nice very nice shoe design yeah again it looks like the verno i think that's great definitely the thing on this page i like that t t pot four pages sweet and we posted about um dave make stuff yeah the skull jewelry we posted about wow so definitely give them a follow that's really cool stuff yeah here's the skull stuff the fantastic cool so shout out to dave make stuff or make some awesome things yeah mushrooms yes even that uh coffee cup yeah i like the shoe it smells like the adidas shoes i like how yeah it gives it away as a like a reference for uh making the shoe and check that out cannot really good i think is that ninja flicks says that it's a tpms tpms i don't know cool all right well i made it on shape so cool nice all right so shout out to dave make stuff or post it up they're great designs and we have some community make stuff that was sent to us shout out to everybody for sending their makes we'll run through them real quick here get the links quick enough all right this is a really awesome build shout out to alistair like men on fingers are posting up their make of the dark saber three printed dark saber prop with prop maker feather wing and a feather and some new pixels this is fantastic this is like this is perfect so these are the man learning comics adorned on the wall that is freaking fantastic i love the length of it and that's a permanent pleasure um and the scripture says uh added the man learning walk in my office gonna hide the wire so you can keep it up that's brilliant yeah that is so cool that's so cool it seems uh okay we got printed in uh isan pet g gray printed on a mini but that's not option here oh okay now mini prusa excellent sweet and uh here's another photo of the post process oh my god gorgeous whoa holy crap that is gorgeous that's so much sanding wow i love it looks great you guys know me i never sand anything so anytime we see somebody go through them just we know how much time and the effort that goes in there yeah this is yeah all right here's another one so okay shout out to i'll start like men again for posting up their make again another one here this is from uh tactical pickle gaming posted up a remix part of another prop this is the key blade from kingdom hearts um so a couple years ago we designed a key blade it's a kind of like a sword that looks like a key and it's from the video game series kingdom hearts gotta give it that backstory but uh looks like a tactile pickle had an issue printing it it says after printing all the parts um it ended up snapping at the smaller red end after printing it again and breaking it again i decided to combine the color in the first blade section together figured i'd upload it in case others find it useful yeah i think folks find it useful i also have snapped mine in that area too because the kiddo is rough but yeah um really cool to see folks remix our stuff and make it work for them and if you are a fan of kingdom hearts there are plenty of kits for making your own key blade yeah cool shout out to tactical pickle gaming sharing their remix one last one or two last ones here come on here from prusa printers this is a make of the raspberry pi hq camera for the pi four so if you're looking for a let's a snap fit case for your raspberry pi hq camera project check this one out um click on it to make it bigger this also looks this is posted up by uh stefan m64 on prusa printers says the hardware to put it together is a bit annoying but this uh but is a bit annoying to source but overall a decent case for the yeah for like hq and pi four yeah finding screws can be hard sometimes but uh looks great way to kind of keep your pie nice and secured cool and to end it off we have another dark another dark saber from the mandalorian star wars i'm like cool so so black sheep studio split this up on prusa printers this is a work in progress as i chucked up i chucked in some random usb leds i had so not the right size quality or amount of leds compared to the near pixels who's the guy but they should do for uh for party in a couple weeks and then maybe my birthday i'll buy the proper leds and feather wing etc also debating making the the track wider i can find a cheaper or stock leds yeah very cool look at that i like how it glows on the inside yeah it's an unexpected effect to see glow on the inside it's pretty cool there that was posted up by black sheep studios cool i'm thinking these dark sabers all right and that's the sweetest community makes shit it's everybody for sharing your makes it's it's a thing i really really makes my day when folks post up for stuff yeah it's like hey it works yeah hey it worked or hey it didn't work or here's a remix that worked for me very cool all right so tonight we have a special show in chell it's gonna be hosted by jp jumpfark's gonna be hosting it this week and then shortly after lamar and phil will be doing ask an engineer on the same uh time schedule it's on wednesdays at eight p.m normally you would say et eastern time but here in america we have this thing called daylight savings time so it's dst so it's eight p.m dst sorry people are probably tuning in to show like hey where's 3d hands like we're over started it cool so uh yeah come into uh show and tell we hope to see you there you can get uh the invites by hanging out in the discord chat room i'll post the stream yard link there a couple of minutes before it starts so get in show us your awesome project cool show it up and uh you'll get a 10% off coupon code uh on ask an engineer it'll start at 8 p.m tonight cool and then tomorrow we have jumpfark's workshop every thursday at 4 p.m what is the daylight savings time dst i don't know hopefully this stays permanent this year i see that the bill is going in to get signed into law so hopefully no more time changes okay on fridays it's normally a deep dive with scott uh scott would be out for a couple weeks and in the meantime we have foamy guy tim will be uh doing the deep dives so deep dives with tim i need to update the spanner so it has tim's face i know we're joking to add like this avatar that he has on there like photoshopped like a little piece of tape on there make it look like we taped it on but i'm sure i'll get his photo once uh gets in the office cool like in the year all right and then uh on sundays is uh from the disability data doing up uh so what is it no the great search for jitki and some sneak peek stuff mondays is the circumfile meeting so if you want to tune in live so you can hear uh what the circumfiles are working up whatever what they're up to and the community at whole it's every monday at 2 p.m daylight savings time cake every monday at 2 p.m no and then tuesdays is on park's part of the week you can get up to 50% off select items so be sure to tune in live because it only works during live the show and that's every tuesday at 4 p.m or 1 p.m pacific time daylight savings time i mean we're wrapping back around wednesdays we do the show in the morning at 11 a.m daylight savings time all right we're on overtime now thank you everybody for joining us sorry for yes denoted as uh standard time shout out to everybody thank you so much for kind words and you know good luck with all your making endeavors we hope everybody is getting into it and keeping busy but until then remember to make a great day yeah see you later in the night see it tonight folks take care bye use it
