Buzz light your helmet from the new movie coming out. I think we are now I was thinking about we were cleaning out the garage and we found one of the old space x helmets. Yeah, the kid put it on and Yeah, maybe some props. I see they have some sort of lead that looks really cool I think the helmet will be cool. We'll see once the movie comes out this week Maybe we'll uh, check it out. But cool. Good. Uh, yeah helmet helmet projects always fun So I think I will add that to my list The the visor part is always difficult to do But uh, maybe we'll just gonna do the same thing I did with the uh space x one. It's just a The mesh. Yeah the mesh the meshy thing some sort of very annoying mesh Cool. That's always fun. Give a little twist on that Um, yeah, so this week is different. No electronics or 3d printing this week. This week was a learning exercise in cnc milling. So we got a lot of Cutoff pieces a lot of scraps of wood and I really wanted to do something with that stuff as paid for saying We were cleaning out the garage. What do we do with all these pieces of wood? So I figured you know, I've always wanted to do wooden lego bricks compatible lego bricks So we made some tests and we figured out how to cnc the top and the bottom of these building bricks to make them compatible with lego bricks So it was a lot of fun to check this one or to figure this one out and um The cnc mill that we have is from bansom tools. It's the desktop PCB mill and it's a nice little machine that can do these really precise parts So what's super cool about this is that I figured out how to do the top first and then I realized well, how am I going to do the bottom? And if you remember our cnc project where we made custom key caps That one required Some very fine position tape that would adhere it to the spoilboard But we figured why not mill the bottom first and then when we're done We can flip it and then use an actual lego plate as the holding jig So that really sparked this whole project using You know lego base plates as the holding fixture to do the top side of these bricks So that was a really fun kind of aha moment And all these bricks just kind of fit into Whatever base plate so you can scale this Kind of workflow To be a bigger base plate. I chose this small base plate just because that's what I have on hand And then I have some of the bigger base plates like a 16 by 16 stud However, that doesn't fit on the bed of my cnc mill actually crash into the uh Into the walls if I were to do anything bigger So you kind of have that ability to kind of create your you can scale it To make whatever size of bricks you want and using fusion 360 We can set up user parameters to make any number of patterns For making more studs or less studs so the way uh the bottom of these Legos, let's take a look at An actual lego brick you notice that the bottom has a deeper pocket deeper pocket than uh than my Um than my wooden piece here, and that's because well these are ejection molded and the less plastic you use Well, the better it's going to be the less Material you're going to use but when you're cnc milling You really don't want to mill away the more material you have to mill The longer it's going to take so I uh reduced some of the features of simplified them So instead of having these really thin walls here that work really well with ABS plastic I just didn't need those so I excluded so I just did not You know add those to the geometry Another thing I did was I I made this a shallow pocket here It only needs to be as deep as the you know tallness of these of these studs So it ends up working out pretty well And when it comes to the weight they feel about the same this one obviously is going to be a little bit harder or a little bit It's going to weigh a little bit more but that kind of adds to the kind of charm of um Of wood you get these beautiful textures and this is uh you can use different types of hard wood. This is uh maple And then I have some cherry And then over here we have purple heart And they're all unfinished just a little bit of light sanding is needed on the bottom here But the tops end up working out really well. So there are no sanding needed on that The tolerance actually hold up fairly well So They're going to hold up the weight and I was able to build A little box here. You can also do like pyramids and stuff But I stuck to the two by four brick just because I wanted to be able to scale this and make a whole batch of them So that's kind of what we did Another thing I did was I wanted to create a custom shape base plate and this is the Adafruit logo I didn't do the bottom the bottom here because I didn't really want to fit this in anywhere But this kind of showcases that you can create any number of shapes and uh add some studs to them Yeah, and these are lego dots So these are these lovely tiles You can make all sorts of fun shapes with them and that's the type of thing I want to do with this one um, but yeah, uh, if you look at some of the Wooden building bricks that you can get off places like amazon. They actually are not compatible with the lego bricks They have different brick heights So I really wanted to make sure that these were these bricks uh work with lego bricks So that was one of the goals there Of course, we've got adabot here He's a little lego minifig that we've designed and released as a free design that folks can print and uh, yeah, that's pretty much it We'll walk through the learn guide fairly quick, but uh, pidge has got a duplo here Duplo are the uh the the plus size bricks There's a question if it is compatible with the duplos and on the bottom they are they fit just like any other lego But on the top because you were mentioning you didn't want to uh mill away all of that Oh, that would fit the bottom, yeah Yeah, so we could mill duplos You can definitely scale up the uh the features like the studs and the tubes And if you did want to have it fit all you have to do is probably keep stepping down a little bit more until you get Oh, that's right. Yeah, you just that's all it needs. You just gotta step down more because otherwise it does fit Yeah, it's just doesn't uh the depth. Yeah, so that yeah So in that way it does yeah does fit or would fit if Uh, you milled in a little bit more. Yeah. Yeah, you're right. Cool. And for those I don't know. Yeah It's the bigger. I think it's like whatever the 4x sized up and a lot of builders use it when they want to Like say they're making big models. Yeah, this is a good way to Have those fillers in there without having so many smaller pieces. Cool. Yes Yeah, so let's uh take a look at the uh At the learn guide and just kind of browse through it the learn guide is uh just went published just went live this morning And we have there all of the recipes the settings the feeds and speeds and we walk through the whole process from Setting up your stock material facing the stock material and then doing the bottom side first and then the top side using the lego base plate as the As the jig holder and then also using a pcb alignment bracket for the bantam tools pcb mill So we'll go through all that stuff, but we'll take a break here to take a look at uh any comments and stuff and people like Cool. This is cool. Yeah, I think if anyone has a cnc mill out there And you got some cutoff pieces give this one a go. It's going to be a little bit different You know when you are using a different cnc machine But the uh the process you should kind of be the same and should be adaptable to uh to your machine All right post links to the video and the learn guides you can follow along step by step Cool. Cool. Do duplo minifigs exist. Yes Don't want to run down and get it, but we have that latest Jurassic park one Yes, you got chris pratt. We got the t-rex and the little baby triceratops. Yes, there are duplers Yeah, it's so cool. Yes. Yes All right, so if you head on over to learn that eight if you're com You can see our learn guide is is there. So the first page is just going to cover um what the guide is about And then the parts So I have the band of tools desktop cnc. Unfortunately, it is no longer being sold But if you do have a band of tools Uh pcb mill or the newer desktop cnc mill. Um, it should work Yeah, because they have about the same uh features. They use the same software Um Yeah, and they both can use the alignment bracket Yeah, they have a different alignment bracket, but again, like I said, it should be adaptable Some of the tools that I used Uh for facing the material meaning I want to get our material to the desired thickness I'm using a 1 eighth inch flat end mill. This is the biggest tool I could use on the pcb mill But if you're using something like the band of tools the desktop cnc, you can use a quarter inch flat end mill This honking tool you can just really run through your material, which is awesome um for the finer Details like the studs and the walls Um, I'm using a 1 16th inch flat end mill This is the fishtail down cut spiral bit. It works really well for top and bottom finishes and if you use one of these, um One of these bits, uh, they do really good And that's one of the reasons why I didn't have to sand the top studs because They just have a really nice finishing on those fishtail end mills Some accessories for the pcb milling machine is the pcb alignment bracket. It's a aluminum bracket and the way Uh, it works is the The the the pcb mill has a conductive spoil board and it's able to probe the bracket to get precise Uh measurements for locating, um, the edges of the bracket and getting a zeroed in Um origin so you can align it precisely onto the alignment bracket and just be One to one perfect Some other things We're using here is the double sided nitto tape a one inch wide Tape this is great for adhering. Um, it's basically cnc milling tape. Uh, it's got a really strong adhesive And uh It's great for uh adhering acrylic well rather not acrylic I would stick to wood with this one if you're doing acrylic you can just use regular double sided scotch tape Um, but I'm milling wood here and this stuff is great for wood And then hardwood material I like to purchase mine from eventables You can get it from your local store, but I like the stuff from eventables because it tends to be Uh, plain surfaced already. So it's nice and flat, but even though They do that it tends to warp During shipping and stuff. So we're actually going to walk through. Um Facing the top and the bottom of the wood so it's precisely flat and square And that's the kind of parts those are all the tools and things that are used Um In the in the cnc project. So let's take a look at the cat files So it's all done in fusion 360 recently fusion 360 um Allowed More folks to get the free license so you can refresh your license if you want to give it a try um, it uses user parameters for the various features and a uh rectangular pattern For making the studs. So all of this is parametric. You can just open that little window and change all the different Features dimensions if you'd like Um, so that's all there there. That's all there for folks Um, what else do we have here and the cnc toolpaths are all A part of fusion. That's what we really like fusion 360 because you can do all the designs It's all parametric and then you have for all of the toolpaths and stuff um For uh milling for cnc milling. So We'll walk through all that stuff, but I also have the gcode files available if you want to just build it as is And you want to make the two by four bricks uh, all the gcode is kind of optimized for the the band and tools pcb mill All right, the next page we're looking at materials. So the different types of materials Hard wood is what I recommend Um, you could use some walnut some cherry or some purple heart or some maple whatever you like um, I found the cherry wood and the maple work the maple wood Uh tends to kind of machine better in my opinion. Um some of the uh other materials like walnut and purple heart tend to have some more course kind of density and uh They have a little bit tighter tolerances. So you might have to sand a little bit more on those woods Um, but that's what I found. Maybe it's uh, maybe it differs on the uh On the actual material, but yeah, that's what I found We start off by measuring and cutting our material If you're getting a half inch material is what I recommend for these two by four bricks You'll want to shave off About a millimeter and a half away normally it's around 12.7 millimeters all the way up to 13.2 millimeters So you are going to want to shave that stuff down either using your plane machine if you have one or a hand plane You also want to consider making your stock You know fit within the dimensions of your build area of your spoil board The maximum build area on the pcb milling machine is 5.5 inches by 4.5 inches by 1.6 inches But I recommend getting a little bit smaller because a lot of the times when you are switching out the tools you need that little bit of spoil board because it that's the way it's able to Align a line and probe the tools z height because it's conductive The the tool will go all the way down to the bed And touch off and when it touches its senses that it is uh, it is metal and that's how it's able to get the z distance the height for the tool So that's how that works But however, you know, you have if you have some cutoff pieces and stuff like that you'll want to update that accordingly So I start off with uh facing the top and the bottom material Um, so like I said, if it's about 13 millimeters thick, I actually want to surface the top Flip it and then surface the bottom and that way I can get it down to the desired thickness, which is 11.5 millimeters. That's actually how thick our bricks are going to be Um If you're new to fusion 360, there is a tool library Which saves you a lot of time So all of the tools that work with the the band of tools Vcbmail are already kind of pre-made for folks They have a json file that you can download from their website And I'll just click on this just to show you um that they have their own kind of learn guide by amanda here They show you how uh kind of how to import your tool library into fusion 360 So then you can just pick a tool and uh ready to go there Really good really nice really good comment by gary tea Reminding everybody that yes maximum build areas is usually just numbers for marketing Definitely make sure That you have padding area like for and three printing like when you uh print out your um, your uh, what is it? The skirt yes the skirt Why always be under your work area So same thing with the height too because it might be 400 The millimeters tall, but it'll crash at the end or like come off the rods or something That's funny. Maybe not so definitely uh add some padding or be aware of your padded area That is required for the tool to fit with inside that area. Yeah So uh the next parts here I walk through modeling the stock um, I find it easier to separate your stock tool pathing From your actual part machining I just tend to do that because it just kind of separates them and you don't have to kind of worry about um Adding a facing operation within the the top or the bottom break So that's why I just like model your just model your stock and then face it that way So I walk through here all of the Panels and things you have to click on to get your stock set up in the manufacturing workspace of fusion 360 So I walk through that we walk through doing the face operation and then here are some feeds and speeds This is really the recipe and it's really, you know built and optimized for the band of tools pcb mil Uh, the band of tools pcb mil has a max rpm of 24 000 um I like to do a cutting feed rate of 1500 millimeters a second That's sort of my default go-to And then the plunge rate is the only other thing I play with but all the other settings I like the defaults because you really don't need to mess with them when it comes to the band of tools pcb Those are mainly the things you want to do how fast is the thing is Is the tool going how fast is the spinning and how fast is it going across do I want to break my bit? Do I have an extra bit? Yeah, and then of course the other thing is the uh, you want to enable multiple depths and then Set limit the maximum step down meaning how many times it's going to step down Depending on the tool So if you're doing the 1 eighth inch tool, which which is the biggest tool you can do on the pcb mil A millimeter is very conservative. So I like doing a millimeter step down Yeah, so that's how I got that set up And then posting the gcode I walked through that I got my own little naming convention where I kind of name The file With the tool first so one one dash eight the operation It's a face and then the size of the stock. It's a hundred by 130 millimeters. That's how I like to name my files Um, so we walked through that we export the gcode and then we import it into the band of tool software So we set that up and just uh update our material Um our material setup and I just kind of walk through all of that stuff there Um, so it's pretty straightforward though All right, and then in the next page, we're actually doing the facing of the stock so um You know installing the tool And then uh, actually using the nitto tape and applying it to the to the surface of your stock Aligning it to the spoil board building the file removing it flipping and repeating And all that stuff. So check those out. It's pretty pretty specific here so the first after our stock is uh um Faced surface to the desired thickness of our bricks We're going to start off with the bottom of the brick So I walk through setting up the tool paths for this Of course the gcode file is already available if you want to just do that But I walk you through here uh doing all the right settings and stuff So we're using a contour operation a 2d contour That just lets you do a simple 2d cutout our bricks don't have any really 3d bits to it So it's just going to do a 2d path over and over again until it cuts out one brick so we walk through that and then After so i'm using a 1 1 8 inch tool to do the contour just because I feel like you can do it faster You don't want to use a small tool to do the full cutout because the smaller thinner tools They just aren't that long so you have to kind of consider that And then the pocket is what we're going to use next the 2d pocket And then we're going to use the 160th inch Uh mill because the 1 8th inch it just can't get in between those tubes So that's why I have to use that uh that 160th inch flat and mill That's kind of my go-to tool for acrylic cutting by the way But yeah, this is wood. So we do want to do a um We want to limit the maximum step down to a half of a millimeter and that's really conservative You could do the full millimeter Especially with hard wood, but I really recommend doing like a half of a millimeter Just so that uh, you can extend the life of your tool, right? Cool And then after we've done the contour after we've done the 2d pocket Now we can start doing a pattern. So you can actually do patterns Of tool paths within the manufacturing work space So I walk you through that and this is where you will want to kind of adjust it to fit Your stock material. So with the stock that I walked through above I was able to do 15 breaks. So that's Five up and then five on the long ways This would be the y-axis and this would be the x-axis You can flip that around if you want and then I have screenshots here and some tags that show you how to add an additional pattern direction because I'm doing it up there and in this ways So you're doing the x and the y And then you can change the instances on how many you want and I'm very You have I kind of figured out the right distance between the breaks so that I could like You know use the most of the stock as possible If you get it too close you'll start to if the spacing is too close between the bricks You might start eating away into one of the bricks. So you kind of have to have this This this good amount of spacing between those bricks when you're doing the pattern Uh, then we export the gcode out and we do the same kind of process before the 2d pocket And that's with the 116th inch ml. So we're pretty much using the same Um Values for the spacing between them. So they have to be consistent And then inside the banded tool software you get a nice visual representation of The parts that are going to be milled On top of your current stock. So here in the screenshot you can see how I'm pretty much using all of the stock on the y and I have a little bit of excess on the x-axis You could actually after this milling is done you could reuse that that flip it around and put it back on and maybe make a You know one by three bricks coming out or something like that. So you could always reuse the excess stock, which I think is pretty clever Um, so we walk through the milling process here I talk about finishing the bottom break. You do want to do a little bit of light sanding And then we start uh test fitting the brick with an actual lego base plate Um, so that's the first one Then we can add more. This is just a I think it's like an eight by eight plate I don't actually use that because I have more bricks. So that's why I picked the four by 12 Um, so then we want to update the top model um to accommodate for whatever Uh amount of bricks we want to do that are going to get uh Snap fitted onto our base plate. So here I have I I turned it from a two by four brick into a four by 12 brick because that's what our jig is going to be So you kind of want to update the top model to reflect whatever your lego base plate you want to choose Uh, so I walk through that setting up the uh the top side stock And then setting up the pocket. So when you're doing the top side, it's much easier now that it's already cut out All you really need to do is the the pocket Using the one sixteenth inch tool Um, yeah, so that's it's a lot easier to do the top side Less less stuff needed. Uh, so we walk through Exporting it out and then updating our material once again to accommodate for the lego base plate So we just update that material thickness And uh, once you bring in the g-code that we've exported it just renders out really nicely In the software in the bandicoot software and uh, yeah, you You get that going you get you get the material updated you get your g-code installed and then There is a a little bit of a procedure for installing the alignment bracket You click a button that says align the bracket and you will change out your 160th inch tool What you want to do is uh Flip the one eighth inch tool so that the blunt edge is facing down and that gets used To probe and touch off the edges of the alignment bracket The um, the sort of alignment bracket has a little kind of wizard that walks you through the steps of installing the tool using the screws uh to attach the Alignment bracket to the spoil board So banded tools are a really good job on on that because like everything is just like ready to go and the procedure is really really nice Um, so once you have your alignment bracket installed. I'm using more nitto tape to fit on the bottom Um, you can see here that the wide tape works out really well for this Because there's not really a lot of surface area on the bottom of a base plate. There's just a bunch of tubes But there's enough tubes there to really adhere to the bed and the nitto tape is really strong stuff So it holds out pretty good Um, so you just want to be as square as possible when you're lining up Uh the uh the base plate To the lower left corner because that's like the origin of where it is And uh once you have that base plate installed with the alignment bracket You can just press fit those blank bricks those bricks um have uh the bottoms all cut out so You can see the top there is nice and kind of blank So once that's all ready to go we can start milling and that's what it looks like at the end. There's no For me there wasn't any um Any cleanup to do on the top side of the brick, which is really nice And to remove them you're just going to apply some pressure and pull them off and but they they they they held they held in place really nicely Um, especially on the first kind of go They have a really nice type fit and as you kind of Play with the bricks and start building stuff the tones is loosen up to the point where they're not as firm But you kind of want that firmness Um the initial, you know milling operation because you want those bricks to stay and put stay in place Test fitting works out really well. What's uh, you get your first batch You can start stacking them to see if they all fit in the right rotations And then you can make a block by like doing a two by doing sets of three Since we cut six here You can create a block just to verify that That they all fit nicely And that's kind of really the whole guide um Lots of fun really great Uh kind of project for doing double-sided operations for milling And i'm going to make some more bricks i'm going to try to do some different sizes Maybe a blue blow as well would be really cool to do a blue blow break Yeah, we have so many spare pieces of wood that we don't want to throw away We don't know what to do with they're too small to really put into a project unless you can Yeah, so i'm gonna make a bunch of them. Yeah, make a bunch of these and And uh, maybe make some bigger ones or something. Yeah, like how this uh, you're able to combine all these together and make like that really cool Like wood that is like uh laid together to make it look all cool. Yeah You do that with the uh plastic ones is able to make a uh a bit of a pyramid And should I open up the lego? Uh, what is it called? Oh the brick builder. Yeah, it's called studio. So there is a piece of CAD software Um by brick link, I believe And I actually modeled it in here so I could show it to you So i'm gonna open it up And uh see what I get here in a second page is going to build something here All I have fire up this CAD So it's called uh brick link studio So search for that and here is my pyramid that I made I'm about to Flip it here So here is the um The the little pyramid that I made Out of it's it's so this little pyramid is made out of nothing but two by four bricks Uh, so in the sidebar here you got all your brick types You can choose the colors and you can kind of add different steps and stuff Um, so this was a cool little build I made Um, I designed it first just to verify how many parts do I need you need about 83 bricks And I guess I've made 83 bricks in total So I think I used just about all them except for this one. I never made a two by two brick Um, but I just threw that in there and just kind of look kind of cool Yeah, do you want to see how to build it? You kind of I don't know if I can hide but anyway, that's uh, that's cool. That's kind of a neat kind of a thing Um, let's go Back into the overhead There it is. I made a house. You made a house Great. You made it a little house Yeah, there's all sorts of um combinations you can do with the bricks Um, yeah So I'll see what other kind of fun builds I can make with the just two by fours And maybe I'll make some other sizes, but I stuck with the two by four. It's kind of your common brick Oh, yeah Lamar, uh, we have to get a approval to make these projects and when you were done It was triggered her childhood memories of nostalgic LEGO building wishing she had these LEGO wooden bricks especially with like, you know the the Going towards like echo friendly, you know, why like, oh, we have you know, you can pose nicely bio plastic How about wooden ones, but we can see why it's pretty hard to make so many of these at mass scale And you can buy uh, some of the wooden eco bricks I think they're called wooden building bricks off of amazon, but they don't work with uh, the LEGOs because you have just a different Maybe it's a legal thing, but the patent has expired. So I don't know what the deal is. Yeah There's also, uh, I think a company out of japan That makes their own bricks out of like bamboo wood and stuff. Yeah, that's cool. Let's get some bamboo All right, cool. Yeah. Yeah And that is a sweet project. It's a good good, uh, refresher and CNC milling and two sided operations and Using some kind of unique methods for uh, as a jig holder this lego plate. That was a really good idea Very fun Yeah, that's what it really is. Yeah, it's a cool project and uh, yeah, a little bit more Yeah, I think we just did like three back-to-back lego projects. Yeah, it's been lego. It will continue Yeah, and just for folks, we will be at Lego land on this sunday our first time how funny we've done so many lego projects We're gonna bring our little adobots. We're gonna bring a couple of these Yeah, I'll think I'll bring some of these two and maybe give them out to anybody who Who might be interested in this type of stuff So I guess we'll return. We got the annual pass. So we'll be there multiple times. Yeah, that's really fun Yeah, I'm looking forward to check out the brick factory I know the one at Disney Springs is pretty cool, but it's you know, not lego land Yeah, that's they have some custom unique stuff that they don't sell anywhere else I really like these lego dots. They're fun to play with. Yeah, they have like a whole section It's a whole like design methodology Here's another kind of thing. I mean, this is actually walnut wood I didn't want to do the bottom because I just wanted to make a bit of a coaster So there's some really fun shapes you can make with With the lego dots So that's pretty neat All right, quick question over from the youtube's honor as asking Any recommendations for a desktop milling machine since Bantam no longer sells their small one Yeah, I think something like the nomad From carbide 3d might be a good option because it's enclosed And it looks like it has a A good method for probing and alignment brackets. So check that one out. I think it's reasonably priced I don't have personal experience with it But check that one out. Of course the the x-carve From ventables is another option. That's kind of a bigger format one So if you want to do big projects, maybe go that route And then of course you could also build your own Melissa who's on the remote team with us. She built her own a CNC router. I think JP built one as well JP built one as well. So you could always Build your own as well Those are going to be the bigger format ones that I believe Might not be closed. So you want to consider lots of things when purchasing your CNC mill Because you're certainly bruce is sad. They no longer sell it. So are we too? So if I could get a hold of them, I would I would say hey, maybe maybe v2 If you try the v2 man, come on. It's a really good machine It's a great like kind of Like it's so compact. I know it's yeah, it's a work of art All right, cool. Let's go ahead and jump into this week's. What are we prototyping? All right, here we go All right, so What we're prototyping this week. We've been watching the new obi-wan Kenobi series and their new hit star They always have to have a cute little robot. I got here one of the lowlita or lola 59 a little companion robots I want to build out So it'll have the two separate servos inside there. I think we're going to do the feather rp 2040 And it's going to do its nice little Little wing action thing. We'll have some of those little button neopixels inside there Um, I don't know if we'll do some sound I'll see if I have enough room to do the speakers on the bottom portion of the body there But as you can see doing the tests and prototypes so it looks like an imperial Yeah, real uh, it's just the glitter black filament that we have already It's the glitter black that we use for all the prototyping just getting all the little details down There was some uh a little bit of struggle to try to get those in there inside of fusion Went from trying to use a loft over to using the revolve I did lose some of the I it looks like in all of the screenshots and then the video that it is kind of elongated So I wasn't able to get that shape in there But it looks just like what it does Yeah, it looks just like a ladybug or the thing that I it reminds me Very most of what was that 80s movie batteries not included Oh, yeah, it was all these little tiny robots that come down from like space. I don't remember What happened? Yeah, it's super cute like The way that they were able to animate and give personalities to To those little robots was so adorable. So I'm I think it's the same company. You've made all these so Definitely We living some of that nostalgia and the retro for that. So yeah, there'll be the uh bottom place That's printing out right now. I have to redo the way that the hinges are It's probably what they're using is a hinge that's on the bottom There is unfortunately going to be a bunch of support material just because of the shape is quite peculiar And uh putting a small drone in it to make it fly that would be cool That would be so cool. But it's like where do you put the uh, maybe on the bottom? I guess like a propeller, but no Uh, we will give out all of the files so people can Yeah Absolutely, yeah Indy Callaway says it's like a cross between a ladybug and a cat. Yeah So probably for the dome, I'll try to figure out how to do that one might not even have one just because of the printing Yeah It might be able to be clear enough to just print the dome in the translucent filament. All right Yeah, cool. Good service. Just starting out with it. So two servos a uh weeks from now. Maybe yeah, yeah It should be ready by then Yeah, just getting the hinges and the shape the rest of the body and all of the mounts for the board and everything But so far, uh, got a nice little shape going to proportions and stuff Yeah, I think so. It's about the size of a hand is what it looks like Cool Bruce says it looks suspiciously like mouse ears You're right Yeah a little bit It's a tiny ears. Yeah, and that's what we're prototyping nice little uh, yeah imperial, uh, lolita Imperial lolita Pretty cool. All right good stuff All right, next up we'll do a little bit of shop talk Oh, yeah, yeah, so Let's get our tomorrow's getting some really cool samples in and we found a source for them So like okay because um Pt wants projects made for it. So like oh, let's get prepared and start figuring out dimensions for modeling. So these are pcbs with Chip leds these are all surface mounted components And you can see there there is a coin cell And a coin cell battery holder But where's the on off switch to turn it on so they use a magnet to have the switch turn the led on and off So when you get a magnet pretty close to it. It's like magic, huh? Yeah Turn it on You're actually advertised as a Gundam model leds So you imagine these could be embedded into all sorts of different objects and models And then you would use a magnet to turn it on and off What a clever way to right turn on and off And so d i think i hit it twice there Yeah, so completely different from the wireless led ones where the power is grabbed by the coils wirelessly This just has the battery inside and you're using the magnet to turn the switch on and off It's the distance. It looks kind of cool magical there when you have it on the bottom and it just turns on Yeah, they're pretty small they're about that big these um Might be different than the ones we get in the stuff and probably just wanted to get some on hand Just so we can start modeling. I think there were 12 dollars for two of them Or maybe one of them So we'll see what what happens. We wanted to share with these these with you folks. It just looks so cool Yeah, you can see there's an icy there. I don't know what it's doing. Maybe something with the power I'll have to let lady to explain what's going on there. I can't get a good focus there, but You know, there's a chip led some sort of so i see and then some sort of Another three pin three-legged ic there So what's going on there? Yeah, and these are green Because Gundam Gundams are green Yeah, I'm sure we're gonna different colors Yeah, these magnets are uh quite small. They're guinea magnets. It does come with magnets, right and they're a little bit bigger And that's uh nice little shop talk. Yeah, we also have another shop talk. Hold on. I forgot Definitely check out the CAD Repo on get hub. We have some new parts that I forgot to talk about the last two weeks So this is the anno rotary uh navigation encoder breakout it has the uh The plastic bit the pins and the pcb and the silkscreen So if you want to make a cool project And embed this into a neat project enclosure You can use the 3d model to kind of get the mounting holes and stuff Um, but yeah, we also have another one. This is the feather s2 I'll be working on the s3 and the other new boards throughout the weeks But I just wanted to share that there are some new parts that you might want and as always if you have some part requests You can add them to the issues tab in the github repo One way to find out when things get added is to subscribe to the github repo Giving it a watch or a star. I guess it's cool And then to see the the list of The new stuff you can click on this over here. It says 180 commits It's this this thing here on the uh top Right you click on that it'll give you a full breakdown of the parts that are added in the date So you can see here. I added a bunch on in may 19th. I added all these things here and all of these were pretty much Uh requests So Let's just let you know like if you add a request, give me a little bit of time and I'll get to it So things like the sixth off imu and the uh, 1.3 htft bonnet Uh, the rgb matrix bonnet for the reservoir pie 40 millimeter speaker the permaprotogizmo All of those the numchuck adapter the mpc 3107 gpo expander et cetera et cetera So under the issues tab you can see here The parts requests and it looks like we've got some new ones here The diy usb htmi parts get those together cool Yeah, that's a fun one So, uh, that is this week's shop doc Some new leds and some new cad files Now we can take a look at community makes all right. We've got a couple of them Last week's community makes was this super cool articulating cat swaddle Try it again. Ket zol kuatol. Ket zol kuatol. This is the feathered serpent from the mezzo-american culture It's a Bit of a snake with with feathers. Sometimes they have wings Super cool articulated design It's printed place and we use some rainbow filaments And the scales and the details little kind of swirls looks really cool. Beautiful If they've used some fishing string here to kind of Demo it in the video a lot of fun It printed out really good It's kind of ready to go when you print it right like you didn't need any finishing or anything. No, that's it And here it is on camera the Silky silky rainbow like the way that they do the changing on the filament spool It was perfect for this so you have like a little belly You have all of the well most of the rainbow colors on his feathers there and on his tail So it looks like it was you know kind of planned with the green being on the top of the scales I didn't plan any of that. It just was perfect in In terms of what color was coming up next to change This is a free model. They're using the little chain Like geometry to have all of these linked together and there is a couple of different sizes too So you can print a smaller one or a bigger one and different orientations as well And the detail on this is fantastic. Yeah, check out all of the little The scales they're able to get in there. Yeah, I like the swirl the kind of square swirls. Mm-hmm very Yeah So this was designed by Colts 3d user Restruction And so you can download it for free off of get um out of colts3d.com There's some photos Also Use some rainbow filament from what it looks like. Definitely where they go pretty cool Lots of folks have already seen it and that's how it prints on the bed. Looks like it was printed uh Flat ways you kind of see the ghosting on that uh prusa i3 Good stuff Super cool And uh, yeah, check out uh Rects Struction on colts 3d and check out some other designs Okay, that was last week's super cool Like you were saying you could put the string on there do a little puppeterian I actually wanted to put the little acrylic uh little sticks on there to do his little head turn, but uh, right at a time And then from this week, I see a bunch of these nozzle models Uh, he's getting posted but I really like this one because it does double as an actual Pen tool holder with a secret compartment on the underneath there You can see where the nozzle gets attached to And then we're using this little base plate here thing with Some screws and a nut to keep it up. I'd like the way that illusion Maintains because at first I was like, how was that tiny little thing in a hold? You know something with you know substantial weight on the top as a holder and that's how I think it was a uh m 8 screw with an m Nut and that does a really good job holding it in place I really like the way that uh, you know, it's a thing you see all the time You know your nozzle for printing turned into an actual it could be a nozzle holder A storage for that And here it is on the overhead We're using this really nice gradient blue to silver um Did have some sort of like twisting action going on here. So you do have some like banding Stradations. Yeah from the color, but It's not too bad. Yeah, it's good for the price. Yeah Take that out there and you can see where the screw Goes in there with the nut and I don't know if I'll be able to yep Take this out here. You have a nice little hidden compartment on the inside So you can have some hidden Nozzles on treats something chocolate in your uh desk Yeah Like that and you have ample amount of space in them Scalable as well. You shouldn't be able to scale it. Yeah There's no scaling on this one Yeah, it seems to be big enough to hold a nice amount of assortment of tools that you use for printing Or just stationary pens and stuff International man of mystery on thing or we're supposed to stop And uh, here's some photos of their build They put like yeah these little beans or something Probably the espresso beans or something right and really nice touch you have that remix of Jen's nozzle bank I like the reverse for that. You can always get a Attribution. Yeah Looks like it was on printables. So here's the source. So what did they Change it? I guess they uh Out of the hidden cavity Okay Yeah, the m8 bolt. Yeah m8 nut cool, but good to give attributions to Jen So Jen did the original here And then the really nice touch is that there are multiple different bases, you know, like a hexagonal base You have a square or a circle base It's the filament that uh is being extruded Cool There's different skills for both models cool Very nice. Alrighty, so there you go. That is this week's uh Time lapses I think we need to make I think there's a couple of models for this week Now can we put the snake inside the nozzle? There's a snake in my nozzle And maybe the smaller version because this is the bigger one Well, and then you can wrap it around Ha ha Choke hold on the nozzle Okay, let's see What else was we going to cover? All right some pretty makes this week, right? Let me get some links together I think we have a few that were sent us that were sent to us So first up we have a make of the perma proto case snap fit case So if you have a perma proto project And you're looking for an enclosure that has vents and some mounting holes and snap fits together Yeah, you can use this And I'm going to look for makes intent in the comments And this was posted up by perusa user mcxx and they say works great I just clicked on it here and it looks like they have it Secured to a piece of wood here. It looks really good. You have lots of Holes and stuff to get wires out. So it looks like it's an esp Tight module Some other cool things. So that's really nice to see All right next up See what I can find here Next one is the nefertiti bust and it looks like they did a hollow version of it I think something got overwritten Oh, yeah, somehow this changed Can you undo something? I like it was select to copy this over. Yeah, I didn't do anything. Hmm. I don't know why it's there twice Supposed to be I don't know but let's take a look at nefertiti then shall we So nefertiti bust all we really did we took the high resolution model from a few years ago and we uh Reduced the polygon count and made it hollow so that folks can Make into a planter but it looks really good in this kind of paramaterial And see if there's any comments that I can read awesome. Thanks And the picture was a bq b1 And some supports and point two resolution Looks good Yeah, okay. Also double as a tool holder nefertiti to a holder cool Are you looking for anything particular? I'm looking for the makes. Yeah makes don't show up like that Unfortunately. Yeah, they show up in the dashboard and then they get lost So it's kind of hard to keep track of these things Um, but I think that was it I could try to browse through my email, but That's fine. We could save for next week. I think that was it looks like we're out of time anyway. Yep I'm out of energy too You can't tell So we'll start closing this. Does anybody have any comments or anything looks like chocolate? It's good Good observation I want chocolate Yes, I want lego chocolate Does anybody want lego chocolate? Certainly bruce is uh saying stop eating my support material for all the uh, I guess the chocolate printers I think that is what you do with the support material It's like uh licking the spoon when you're uh making cake Yeah Cool. Thank you bruce. Great comment. Pleasure to be able to catch up with you all this week I hope everybody's doing well. In other words a quick comment or a question from loy on the desert kiss Uh Dice tower I'm thinking about one day eight hours. Does that seem about right? Yeah, that's usually how long these take Especially a nice little big model like that's a big skull And uh, I want to go print that now. It's so cool Cool All right We got a full lineup of shows for the rest of the week starting with later tonight We're gonna have show and tell a special edition hosted by liz clark. Cool. We'll be there Yeah, and then the following week we'll be hosted by jp john park and then the following after that will be us So it'll be liz jp and then me and Pedro. Yeah So we we got this sometimes the rest of this month as uh, as shown on to show and tell It's just called show and tell. I don't know why it's s ena show and tell And then immediately after the regular, uh, ask an engineer. It's like 3 p.m. Eastern time Uh full hour of the marfil open source hardware python hardware Uh, do we do the ion mpi? I think so and then of course all the cool stuff Secret products things that's coming out maybe a time lapse of that disney building And maybe some new buildings. Yeah, they're looking at looks pretty sweet. Did I spill the beans? Oh my beans are all over the place All right, and then tomorrow thursday every thursday at 4 p.m. Eastern time is john park's workshop tune in to See john do all the crazy cookie funness Modular synth tape decks retro gears Great assortment of fun stuff. They're a cool star trek. Uh, yeah, and he's back this week too. He did less yesterday's, uh, tuesday show Momos there hold on fridays is deep dives with tim So you can tune in every friday at 2 p.m. Pacific or 5 p.m. Eastern To tune in to uh, what's what tim is working on? Very cool. And then on sundays is, uh Where's that? There it is. The desk of lady aida the desk of lady aida where you can see the great search The great search with digikeet sponsored by digikeet and all sorts of other fun cool stuff samples Whatever else they got cookin. Oh man. I want that black ice cream now Yeah, I want some black ice cream for sure It's a licorice. I don't know Very cool And then on mondays We have the circuit python meeting Uh with the exception of us holidays That'll happen on tuesdays the following day But this week it was on a monday every monday at 2 p.m. Eastern time and it happens in the discord chat room And then on tuesdays is jp's product pick of the week Every tuesday at 4 p.m. Eastern or 1 p.m. Pacific you get up to 50 off select items this week It was a high density neopixel strip those can get pretty pricey.
