Welcome to Bay Area Maker Faire 2018 This is such a great show. This is so large and people are bringing all their projects and all the stuff they’re doing over the years. So, yeah, why don’t we go and check some of those out, let’s go! [MUSIC] [Music]! Thank you, – Adam 3d for sponsoring this year’s trip to make a fair pay area. All right, we’re here with Eric and his 3d printed engine project like every time. I need be someone here. It’s just getting better and better. This is so good, See you making 3d printed engines. Is it is to visualize is to learn about them to visualize to learn about it for somebody to build the model and have an engine they like, or learn about the inner workings of the engine and transmission and the see how everything goes together or or have a hobby and these are all. I mean, you couldn’t run gas through them and buy them, but they are accurate. I mean, this and everything moves as it should. In real engine, everything’s designed off the real thing, so it functions all the moving parts to interact with each other, just like the real thing. What’s your favorite ones out of the ones you’ve made so far is the flathead. The v8 Flathead Coats. It’s the most detailed. How long does it take to to model up point of reason? And what do you start with? I start with the basic block, and but I haven’t really kept track of how long it takes to model. It’s a lot, you know, and I don’t think I want to start keeping track of it. You’ve got electronics attached to them. You have motors in here. You have seven rpm sensor. Yeah, it’s just a little rpm to show you the speed of the output and how it changes when you chip the gears, but and there’s little. Leds as spark plugs that go off right win it. They should in the real engine. Show you how the top dead center and everything works in it doing suspension -. Yeah, they do flex a little bit. They’re glued together to make everything more solid for the for the show. Have you become -? How many individual parts go into one engine? There’s parts lists online. I don’t, I don’t know exactly how many on each one. There’s a good amount in some of them. The more complex transmissions have quite a few more parts as mentioned parts lists online. People can’t find actually these engines online. Most of the models are online. They’re open source because I come with instructions. Parts lists and I sell hardware kits if they wanted to purchase the non printed parts from me, But everything’s on Thingiverse. Sorry, very nice. Thanks for your time. Yeah, no problem, so here with the Diego. From what is now make a muscle, some of you out. There might know you from DS maker, so that is to be a 3d printer company. Now you’re making linear actuators, right. Yes, that’s right, yeah. I started with the buco bamboo. Quito 3d printers and now I transitioned to the maker muscle actuator. It’s a very customizable activator for makers, so it’s basically a more accessible and less effort to use version of like pneumatic actuators itself. Yeah, yeah, absolutely, yeah. I just use a regular Stepper Motors like the 3d printers have already. And I actually got those try. Namek drivers on mine. Because I saw your video about them, and I’m like, I gotta use these for these because they’re a lot quieter. But the point is that there are customizable, so the problem I had is I was looking for an actuator for a 3d scanner, and then I couldn’t find the right actuator, So I’m like, why isn’t there a customizable one we could? I can make the right size or the right screw pitch and everything. So so you’ve got. You’ve got that setup right there. That’s a connect a device up there, right, and then you’re just moving it around. You basically swiping it up and down. I guess, yeah, so it goes up and down, and but this telescope’s up to about six seven feet. Oh, wow, those really tall people. Cuz You got to scan the top of their heads, so it has to kind of. Look down a little bit, your dad. You got a 10-1 set up How much it can lift any demo, The the power that you know for lifting things. And it’s about ten pounds down there on our regular kit. Our starter kit. It’s pretty good. It’s pretty good. We’ve got some different motor options over here, and you’ve also got these things you’ve been walking around with these. I think that they’re they’re super nice. Yeah, what would it be? The idea come from core. I just wanted to do something with a bunch of actuators on it. And this is just kind of like a robotic flower. I guess, so that’s just for show, but it’s kind of fun. I want to do something attention-getting. It definitely looks straight, all right. Where can people find you? Make a mustache. Comm maker muscle comm. Yeah, or dates maker, So we’re hitting the print about Booth, and I’m here Is Chris from make C and Yeah, Brook. Actually, he’s a big fan of your work. What did he bring here? Sure, so this is a 600 watt 3d printed motor. It’s a haul back motor design. It was engineered by our senior engineer. Christoph flamer, who’s known for some of his mechanical clock designs. This is a really interesting design because it’s almost exclusively 3d printed parts. Even the core here that’s wound is made with a ferrous material. It happens to be an iron based material. We got from proto pasta and this one is one that brick at Printrbot printed out for us and put together. This is a fantastic motor. It could be used to drive a small electric vehicle, a garbage disposal, a blender and that’s it. This is this no joke. This is a real motor. It’s a foot fully functional motor and this will sustain 600 watts. It runs about 6,000 rpm. We also, what’s interesting about this too. Is that it’s a derivative of a younger generation design that was a 60 watt motor. So part of what we’re about at Bake C is tracking the evolution of these designs as they get improved. We’ve seen these now in a wind turbine that makes electricity. We have a number of other interesting object designs that are online, so we’d love people to come visit. Check us out, you’re basically a platform for this sort of design to be shared, absolutely, so our strength is in providing a place for individual designers and teams to collaborate on sophisticated print designs that consist of more than just files so all of the supporting intellectual property notes videos imagery. And we have a place that you can share privately with your own teams or you can make it available to the rest of the world and we’ll help you share safely. Keep track of your work. Sounds great. Thank you, thanks for having us, all right so here with the O Drive and you guys make a well driver system for what exactly and why? Yeah, so it’s a brushless motor controller it. He controls the same kind of motor brushless motors that you used on. Electric skateboards and drones and that kind of stuff. But we use encoder feedback to drive it about 50 times more precise than a stepper motor. Wow, then a stepper motor. You say yeah, so so a stepper motor. We have like a hundred to two hundred steps, revolution, full stepping, and we do well. It depends on the encoder. But they could re, like has 8,000 counts per revolution. Yeah, so you’re getting all the torque and all the efficiency out of a brushless, DC. Motor, but you’re still getting the positional accuracy, so your board handles both the stepper driver driving well, brushless, driver and the Pid Loop control, right, that’s right, so we we do the high current switching. We have a bunch like half. The board is just power. Mosfets so we do all the high current control, but then yeah, we have the the velocity tracking the position tracking all that PID loop is doing closed loop control, and you know, staying on target. So how much is one of those boards? It has two channels on it, right. How much is a motion system built around that right, so our our we have two boards. One is 24 volts. One is 48 volts. So one is twice the power than the other one. The baseline one is a hundred and nineteen dollars for that drives two motors, so so just under $70 per motor for the driver. Yeah, and of course, your hardware is all open source and the software is as well. So if someone wanted to, you know, could fight together with teensy and somebody s. Cs, is that gonna work as well, right, yeah? I could show you later how you would do that. We have it hacked, you see? I can show you where you plug it in. Yeah, the hardest part by far the hardest part has been getting the hardware right so so. I think it might work, but you you might get, you know, some current, some inductance something wrong, and and and that might not be as easy as you think that shouldn’t stop you from trying, go ahead. We have a community where bunch of people who are building. Motor controllers are hanging out, so come join our community. If you have questions about motor control. What are you using? The control is for it, is it? Just, you know, you showing off like a motorized shopping cart. Today, are they using it? For that sort of thing, or is it more of the pick-and-place positioning high speed kind of thing? Oh, it’s it’s so diverse. We have so many different applications from users in our community me personally. I have this speaking place demo. And yeah, like you said the shopping cart. I’m building a robot arm as well. There are people who want to use it for 3d printing, although it might be a bit fast for 3d printing, it depends there are some people who want to make this string driven, extremely high speed robots, pen plotters. It’s just everything robotics where you need speed and you also mention you’re gonna have these as a compact package like a NEMA 23 Nema 17 maybe at some point that he just feed power in step direction. It’s gonna work like a step a little bit better. Yeah, absolutely, we have. Our next product is going to be a little board that sits on the back of a brushless motor. Pass the encoder all built in you basically just feed it power and some form of control. My personal favorite is canvas. You can network the motors all around and get feedback for everything, but they’ll be a step direction input as well. Straight-up plug-and-play solutions awesome. Well, good talking to you. It looks like you got a good product code and yeah, and thanks for making the open-source that’s that’s always. I mean, my hope is that there. There’s people who want to build, like, really heavy, like BattleBots kind of motor controller have talked to me and said, you know, we really like the logic that you have, but we want more current, and I tell them, you know. What just take the design add? Some really beefy fats and it should should work. We’ve written the software all modular, so you should be able to replace the low level of Support Package, and then the rest should just work. Are you probably going to make outside? Maybe one day so. Antonia, you designed all these theme park rides for 3d printing. You just enjoy it, just cuz. I mean, I growing up with theme parks. All my life for like this right over here. This is a new spray cans. It’s kind of your typical spinning rod. You’d see at, like a fair or theme park in so. I’ve got all of these rides all the time, and I just I haven’t a thing for therapy, and obviously that most people doing yeah, combined everything so just put one and one together, like like theme park rides. They don’t really have a purpose other than just to spin people around and just make them go everywhere. They’re dressed for fun. – right, they’re just for fun, and but there’s a lot of Education of stuff that can be learned from stuff like that like electronics, and why are pneumatic system? What that looks like this is like a straight model and so like these are what are called. Paul’s and when you’re on a ride, you have over the shoulder restraint that this is kind of little typical clicking sound over here, and that is basically the mechanism that keeps there. You walked into the right Vice. So you’ve got a cyclone heave. Got a drop tower. You’ve got a waterslide. The disco, which is kind of like the flying. UFO kind of ride that you would see a bunch of other parts. They’re extremely popular and you designed all these yourself. How long did it take you to design each one? Each of them they vary a lot. This was probably the fastest turn over, and this probably took like firm conception to completion was like maybe a month month and a half to maybe two months at most, but pretty obviously what takes the longest, so a lot of everything kind of repeatable some of them. I did contact the manufacturer about like dimensions and stuff like that, and some were more responsive than others, and some of them might just have set wing it and just kind of hope that its proportional use photos, the photo’s reference photos. Some of them do not dimensions online. This is a dimensionally accurate scale model of a Zamperla giant discovery. It’s kind of the large pendulum rides that you know, it’s been, You know, they swing it extreme up in the air. So yeah, so that’s that one everything here. It’s just just just cuz everything here. The CS3 print and everything is free to download on Thingiverse and probably my mini factory. I don’t enjoyed anything because I don’t see the point of all these things like that. So people just search for tiny rides. Yep, tiny rides on Instagram, tiny are that tiny rights 3d on Instagram because someone already had tiny rights and on Thingiverse at tiny rights and not without the 3d and also on Youtube for coaster labs, which is kind of a mishmash so like coaster. Labs is my Youtube channel for theme parks, But tiny rights is just the models. Well, awesome project. Thank you, okay so. I hope you enjoyed that if I missed anything. Let me know if you were here. Let me know in the comments below what your favorite project was at Bay Area. Make it for 2018 but as always thanks for watching hope you enjoyed, and I’ll see you in the next one [Music].
