 Really, what is this everybody and welcome to show and tell it's me lady with me. Mr. Lady Ada. I'm camera control We're broadcasting live from the aid food factory in downtown Manhattan But enough about us what you're here for is to see all the cool cats and kittens in the maker community Come by show what they're doing. Yeah, a bunch of people from Ada fruit did you key and friends of ours open hardware? It's a whole it's a whole collection of people It's a make things so let's start it off. So coming up soon I've been talking about this on ask an engineer. Yes, and more for 10 years Well, no, oh, yeah, but but this is but this this event is someone Well, Michael tells us how many years have been doing it, but it's open hardware month it is and Hello Everybody a little bit about yourself what you're doing and What is October? All right, so let me go let me go last question first October Is open hardware month? So that's super important. I am Michael Weinberg I am among other things the president of the board of the open source hardware association And so I want to tell everyone that October is open hardware month And it's a month to celebrate fun open hardware things. We were talking before the show I don't know that there's like a classic thing you hang up for open hardware month yet But if you have ideas let us Yeah, right, this is like a real good opportunity There's like a whole universe of stuff happening for open hardware month I can talk about the exciting things or I can wait a second, but I'm happy to jump in and tell you all the things Yeah, yeah, we're gonna yeah take a couple minutes and tell us everything that's going on And then we're gonna keep going to the the guests. I know for us Tell you what we're doing real fast. Yeah, we're going to certify more open source hardware. Hey That's what we're gonna do and everyone else should too, but what else is going on? So yeah, that is a great thing to do for open hardware month is to certify open source hardware It may it's free and easy to show everyone that your hardware is open hardware It means to open hardware definition the other exciting things that are happening for open hardware month first We are now we've just kicked off the board election season So if you are interested in being a board member of the open source hardware association Or you know someone who would be an amazing board member of the open source hardware association Don't be shy go to the site. I have to self nominate to prove that you want to do it We really want some some people to come in and do it. We've got a bunch of slots open So think about being a board member if you are interested in who is going to be a board member But you don't think a board member is quite right for you all of the open source hardware association members vote for the Board members so if you want to join the open source hardware association you get to vote to decide who's on that board We're also going to have a member meeting this month So this is a great time to join ashua and get more involved I have so many things that I have to I have to look down on my list The next thing is we just posted a job for a new community coordinator So if you are someone who loves the open source hardware community And you want to be part of the bridge between Ashwa and the community and the community in ashua and working back and forth and connecting everyone Also go to the ashua site ashua.org check out that job description. It's a part-time job You get to do all of the fun important stuff. We do it ashua. You'll be super connected It's a great job for the right person The last two things I want to mention is in addition to certifying things which is always fantastic We also have people who are hosting either in person or virtually Open hardware events this month for open or for next next month for open hardware a month So if you go to the open hardware a month site, that's ohm.ashua.org You can check out Some kits and some things you can do to host those events in your community Again in person virtually whatever is safe and people are comfortable with And then I want to tease something that we're not quite ready to roll out But I want to mention it for us breaking news Yeah, so so I hope you're sitting down. Um, we there's been a lot of talk in the open hardware community about FPGAs and what it means to do open FPGAs and like our FPGAs hardware. Are they software? What's going on? We've been talking to some people. We've been putting together some best practices And we're going to be rolling those out for people In the next couple weeks during open hardware month. So keep your eye open for that if you are An FPGA super fan and you want to know about this Yes, there's open more open tool chains For FPGA, this is perfect timing like we're actually starting to I mean you can't buy FPGAs right now because there aren't any on planet earth But the minute they are all available again. Um, a lot of people have been designing chips Um with you know ice 40 and other open tool chains And it would be so cool to have a top to bottom open source chip out there The other thing that's happened in the last, um, few years is the expectations from customers users community is the thing they're using has open source components open source Files open source tool chains, and I think we're going to continue to see More forms of advanced stuff like FPGA is like, oh man, that's crazy. What are we going to do? But I think, um Having having the open source hardware community in particular Um being able to know that like, oh, this is open. This is certified. This is these are the tool chains. You're not it's not the NDA trial where like there's so many things in that world kind of like back in the day When you would buy a dev board and it would be like a thousand bucks or be really expensive and you had to use the, uh, the proprietary commercial Software that's over. You can't you couldn't even do that now now It's all about how do you get it into the hands of as many people and usually that's open source hardware Yay. All right. Well, thanks for coming by Michael. It's good to see you Thanks so much. Good to see you too and happy open heart for a month. All right. You can come back any Wednesday in october if you want All right. Yeah All right And speaking of open source hardware I'm pretty sure digikey is the biggest supplier of of open source Hardware components open source hardware I'm pretty sure they are someone someone will correct me if i'm if i'm wrong, but um, take it away kevin Well, I don't think you're wrong. I don't think i'm only the largest supplier of it We're also a huge supporter of open source hardware. Yeah We love the guys that the the whole team at ashua anybody that creates open source hardware It's amazing to be a part of the whole the whole community and creating things that everybody loves And how else would you learn technology without open source hardware? I'll say this this is gonna This is some kudos or sometimes we say hug report here at adafruit out of all Of the companies that are in like the the digikey Universes, you know aro. There's newark. There's mouser and everything digikey is the one who first adopted Working with open source hardware companies Getting them in their stores And I think that's one of the things that has set them apart from others like digikey is a go-to place for Usually when someone's like, oh, I'm gonna do open source hardware. Where should I get a thing? Usually it's it's digikey They they say first and I think that's because of the not only just like the Stocking of the stuff, but you're always you're in the community too. So kudos to everyone at digikey including, you know Marketing doesn't sometimes get credit for stuff, but the the marketers at digikey I think we're smart to to see that was the way to get into Um engineers heads and so we have all the components and more It's really amazing the role that it's taken us down as a company and All of us on the teams as individuals as well. I mean it it's so much fun. It's rewarding. It's exciting Yeah And then one last one last thing because this is open hardware month and kevin's here and michael's here So one other thing when you buy stuff from digikey or you buy stuff from aida fruit Often it's professional engineers and you often want to turn it into a commercial application You can do that with open source and open source. They do that software and hardware You can't do that with other things right and even to this day some people will email us or ask or say something about like Oh, can I use this? Oh, I see you have a license. Oh, I see this on the digikey side It's you know Open open source hardware and software by the way has made an impact on The kind of tools that are available and the kind of licenses that are available So when I started, you know, and I'm not even that I'm old that'll you know I started 15 years ago doing electronics Data there's really common to have data sheets be under nda tool chains be under nda Um code was not like freely licensible and I'm actually when I now get chips and sensors Code is now on github Yeah, like that. I remember the first time I saw like I think it was bosh They put like code for one of their chips on github and I was shocked. It was shocking, right? It was like There's like a llama By your house it's like what's going on ask companies like digikey. Oh, we want tons of people to use our thing and Digikey is like, oh, like here's this like maker thing. Here's a show and tell here's this other stuff. So Anyways, it's good for and it's good for everybody It's like it's like so cool to have freely like I'm seeing it mit bsd License source code for chips is now available It makes it so much even easier to collaborate with people like there's code that we can never release because the company That you know the the firmware is is not freely licensed. I can't share it I can't have the community improve on it because it's under at Most of the time that's a dead end and and we we try to uh steer away from that. It's some old stuff It's not a lot of new stuff. Anyways back to you remember what what the cost of an embedded design was 20 years ago Unreal just to be able to do any kind of an embedded I mean The chip, you know, you'd have to get the the e-prom program You know chip lockdown 20 bucks a piece. Yeah, the tool chain only ran on windows So it didn't even run on Linux. Yeah It's amazing where everything has came and you know, thanks to aida fruit and the different companies I created Pay for compiler kids these days. By the way, do not remember that you have to pay for a compiler. Yeah $800. Yeah, I don't do that anymore. Yeah. All right. So sorry like to rail a little bit kevin What else you got going on? There's hardware month. So speaking of learning open source hardware I did want to share a little bit on our back to school program that Getting students interested into open source hardware and creating designs students can register and win cool prizes share some uh A cool project or a cool design that you have it doesn't have to be functioning Just share something cool with us and get your name entered to win some cool prizes Which one of these prizes Happens to be an Hardware product. Yeah And I You can enter open source hardware and win open source hardware. I love it. It's a circle of life You can get I dare you guys to create a better game than I have a little fire truck Okay Well, there's a there's a siren outside. So, yes That's the game. That's the space made of the sound effects make codes. Cool It is all right everybody enter all right free stuff Cool so much kevin and could you drop the link in the chat after your I I absolutely can I'll drop the chat and it's uh digki.com slash back to school with the number two back to school All right. Thank you so much kevin and happy open hardware months. All right. You guys take care. All right, sweet All right Hey, what's up? How's it going trev? You working on a cool app that um Some folks have seen but some folks haven't you want to talk about? Sure. I'll show you right now. Let me uh share my screen All right, can you guys see that? Yes. Yeah, I see us I see us cool Sweet Awesome. All right. So this is the piley back. So it's a it's a very simple app Basically, where it does is it takes example code and libraries from the interfruit learn system Uh, then it transfers that same code And libraries to your device and I'll show you right now Here we go. You got a blue fruit express right here. Yeah Okay, and then should there be should there be anything on your screen besides the show and tell thing Or is that your other monitor? Other monitor Yeah, or is there something that because we just see the show and tell screen with the little Really? Oh, no We're going All right, let me try it too Oh, no Yeah, oh no trev is gone. That's how it is the app makes people teleport. Yeah Well, i'm gonna hop over to um, you're gonna brand i'm gonna go to brand and then we'll pop back over to trev afterwards Okay, brad Hey, brad, uh, I wanted trev to finish because I was entering the the jahee school thing We'll tell if we see trev or pop and we'll tell him to hang hang back for a minute No problem So this past week, um, the aida fruit i o team and I Have finished like revealing and launching whippersnapper to the public Which is awesome. So now you don't need an invite from me And you can go straight to the aida fruit learning system to put the screen. Yeah. Yeah, that'd be great. Okay, cool And it's under new guides and we have a whole quick start for this And you can also visit it by going to i o dot data fruit dot com slash whippersnapper And for those who don't know what this is and don't know what i'm talking about It's an interface for aida fruit i o which is our internet of things service. Um, and it Makes any wi-fi capable board Into an iot device and you don't have to program So it's a no code solution And you can plug in your sensors and you can plug in your actuators And you can interact if you're the board from the internet And we've been working on it for about a year. I think we started like mid September sort of like looking and researching it Over last year and then we started mid september last year. So it's been a year And it's finally out. Yay All right, well, we'll be showing a video um on our show tonight and uh talking about this and more So if folks want to try this out, what do they do? They go to i o dot aida fruit dot com slash whippersnapper All right, cool. Okay. Thanks brad. All right. Thank you so much brad Okay, next up. Let's pop over to gp. Can you show us some what's going on? Hey Well, I'll tell you what i've can you hear me first of all? Yes. Yes, sweet So i've been working with these cool little, uh leds that we have that are um wireless and battery-less and they get their power Transformed to them by an inductive coil And i've added A set of lights to this little car of mine. So you'll see here. This is a uh, kind of like a matchbox car It's a an autobianchi. I must have gotten when I was a kid in italy Uh, and I've had it forever and ever and it happens to be just the right size to do this Which is add some sweet sweet lighting No batteries no wires and you can see the lights will go off when I remove them from the range of the coil It's hidden under this little mat here, which I'll reveal A magician shouldn't reveal their tricks, but I've just done that And so you can see here you can even uh drive into the range of the coil and me a boop boop And you'll see also, uh, you might be able to see I've got some red and yellow lights in there to act like little, uh How that's actually really nice that kind of like, you know, what's interesting is I think um You know for people who do like miniature Photography this could be a really because it's yeah Yes, you can tell it's a miniature because of the the quality, but it's like the lighting doesn't look miniature Yeah For sure. Yeah, there's lots of gaps in there you can see through so you're not fooling anyone with it But it's really adorable and it's uh kind of nice because it means you can add these these are uh, you know We get 10 of these little leds in a pack. This is the small little five watt coil Or five volt coil five watt. That'll be awesome. Um And You can just stick them in your model and forget about it and then Set them onto the coil to light them up, but it's not like they're stuck in some lighting setup or whatever They're just kind of part of part of the thing now. Um, so I'm not impressed with these and uh, I'm having fun Trying them out in some different modeling environments, uh and applications. Uh, and I'm also Building a little display shelf thing that embeds a couple of the big coils so that you can do like a big Gundam model or some other thing that can display Both, uh from the bottom up and from the back as far as what angle the coil Yeah, yeah, it's more more cover everything. I feel like this is a preview of like next year's tesla quino Where they're like, we're just gonna put coils everywhere This is pretty much a tesla. We're just gonna put coils everywhere sprinkle leds on it's really the most effective way If you put coils everywhere, then we don't have to worry about power. Okay. Yeah, this All right, thanks so much of you about to get merged into a spec. Yeah All right, thank you. All right. All right. Next up. Let's get a jeff and jeff's kitten printer Yeah, so I was browsing um hackaday as you do and there was a project Where somebody had written arduino code to interface with these little thermal printers and of course it's a cat So I had to pick that one and I said let's do a guide so Check out the guide on the interfruit learning system and I've got some Uh pre-rendered images, but we also walk you through Yeah, uh, so they are these lovely little um dithered Dithered come on we're gonna zoom in there. So little we'll have done images if we would focus Anyway, that's too much to ask but you wanted the live demo so I've prepared a special image just for tonight This is not this is not in the guide That's really fast I can't even print you a printer here I know you should replace our printer with with this thing. Yeah. Yeah next time I come back to new york. That's what we'll do That's cool. That's amazing So you just load up the file and then you can print it over bluetooth Yeah, there are a couple of steps, but you put your files on the circuit pie drive Um, and then you can select through them on the menu with the tiny print you can see down there at the bottom Maybe it's changing the file name and then just print Whichever one you picked So fun pick one up on what a weird coincidence. It's the same image Uh, you can check out the guide and if you want one pick one up The printer is on of course that website But the clue is on adafruit and it'll work with any of our bluetooth boards too. So I've only tested it with this one And I had a frustrating experience trying to do it on raspberry pi, but it should work like on a feather sense or Whichever other ones have Ironically sometimes, you know native bluetooth works better because the blue the raspberry pi does hdi over york And so it's like, you know, it's it's great for like advertising But then it's like i'm sending 300 kilobytes and it's like i'm not going to do that Right. Yeah, I mean that's that's exactly how it was It would it would just get a little ways and then I'd get kernel errors and i'm like no I'm not going to debug this today. I'm gonna say this works on the feather and that's it works It works surprisingly well. I feel like they should have made the Mouth thing underneath the eyes like a nose a little bit bigger. So it looks like the cat is just like throwing up The prints I feel like there was a missed opportunity there, but yeah, I mean, there are a lot of different cute shapes So maybe go check them out and find one that fits you better. All right. Well, thanks so much All right, y'all have a good one. Yeah, jeff's cute cat. All right next up. All right next up Pedro what you got going on? Hey, what's up folks? So we got our hands on the led glasses. We wanted to 3d print a little frame So this little three piece frame that you just kind of snapped together. It's got some screws And I got philbe's code his demo code for the audio visualizer stuff. So I got that running right now Um, so folks want to 3d print one, um, this will fit any feather compatible board Just get some screws and some hex nuts and you can attach it to one of these little arms And for power, I just have this micro USB cable with this little lipstick battery And what's really nice is I got these little nose pads because it was kind of roughen up my nose But uh, let me go ahead and put them on now and see if I can fit it over my existing glasses Yes, there we go. Maybe that fits. Looking good. Yeah, it kind of fits. Looks great Very good. Nice. You're ready to get on there. Yeah, give me a beat Pedro So so y'all can 3d print your own frame if you got a pair and uh, if you don't have a pair, um sign up for um When they're back in stock All right. Thank you. Very cool. All right, folks Next up Liz. What's going on? Liz? Hello, how's it going? Hello So this is the midi melody maker that I worked on with nanny last year And I really wanted to interface it more with a euro rack So we've got here's just a little dev board. Um, that takes a gate in signal Um, so I'll turn up the volume And so now it's sending the surga python the different signals Still going through midi So I'm using soul to convert the midi messages To one be awkward just how notes get translated in euro rack, but I'm hoping to eventually make this whole thing like a euro rack. Um Thing so this is kind of the first step in that so I just broke out these pins from the what had been the modulation pot So Awesome. It's always since time at the lis household. Yes I love it All right. Thanks. Liz. All right. Thank you so much, Liz All right, next up michael Hello, michael What'd you get going on? So I absolutely love 3d printing. Um, and something I've been messing around with has been embedding magnets into the 3d prints So a little time to This camera here Um, and yeah, I'm using this translucent plastic so you can see what I'm talking about And I made this little thing last week just uh, just as a little test And I have a white board up here so you can see that it does indeed It is magnetized. Um, and the way it's working The way I have it set up here in the slicer At that specific layer Like I basically have a bullion or like a little hole basically in there And I just have it so it will Want to switch the filament So it basically pauses the print and then I just put a dab of super glue in there And then press like these tiny little magnets in there that I got from a digi key And yeah, uh, so basically that's how you can get Uh embedded magnets in a print So yeah, all right. I think it's cool. I love it when people, you know It's like you get a tool and then you're like, how can I do things that it wasn't really meant to do like I always love You know running a tool and stopping at a time and then changing something around and then running it again And uh, I used to do that with like, um my laser writer. Yeah, that's super fun We also I was thinking about magnets and how you could embed them and things But then you have to figure out where they are and uh, we have this magnetic paper It's this yeah, yeah, yeah, and you put it we we tested it with like an ipad. Oh, like here's where all the magnets are inside of the back Yeah, that's super fun. All right. Well, it looks great. I love I love that you're you're pushing the tool the tooling to the next next step That's right Thanks, that's work Okay, good to see you. All right. I think And that's our show we finished right on time. Thank you everybody. That's show and tell We do this every single week at 7 30 p.m. Next week jp's hosting um, and then uh, we'll see if uh We're hosting next week. We're trying to alternate Um, because wednesdays have been really busy recently. So we'll see everybody every every day's been really busy. Yeah We'll see everybody next week. Uh In some way shape or form for show and tell and in a couple minutes ask an engineer. Thanks everybody see you in five minutes
