 Lady Aida what is this? Hey all you cool cats and kittens and welcome to show and tell to me Lady Aida With me mr. Lady Aida we're here at the Adafruit factory in downtown Manhattan We're gonna check in with people from around the Maker Hacker Craft or roboticist community see what they're up to you. I got a bunch of people Thanks to JP for hosting last week's show and tell but we're back. I know you missed us I love being back. I love being a turtle. Thank you so much everyone For helping us kick off this year everybody's gone So we were able to take off our mess. Please everyone continue to stay safe as we all surf this wave This week starting it off is Jay for digikey. Hey Jay. What you got going on this week? Okay, so I'm working on this new wearable robot that I have named multi It's a little robot that actually has a camera size on because recently I am going to be doing a lot more recording and like videography type stuff for my projects So I've been working on a wearable robot that I can like have around my area and then like look around Like record stuff for me because I sometimes mess up and forget to record important things and then have to like Fake it and it's never the same like I can't get the same energy sometimes Create something that can I can constantly have going on So multi is using a raspberry pi as a brain as a camera in here and the eyes for me that way I know where to look But it's using a mini maestro for the servo movements right now I'm still getting the programming together. It still is not perfect It still has some design flaws I'm working on but Yes, I've been working on for the last Two weeks is January right? Yeah, two weeks. Oh, I love it. Yeah, it's so cool We we post a lot of little short videos all throughout the week on all the social channels and stuff and I hear you We just had to figure out like how do we always make sure we do some because we'll do something We're like, oh no We forgot to hit record or like I didn't check the mic on it and like the last 15 minutes There was nothing going on so Looking forward to what you come up with If you could figure out something That will let you know if you're live broadcasting or not, that's also helpful to if you do life Yeah, I thought about that which right now I'm just putting this to be my facial recognition so I can just turn them on and plug them up and just Get me and while I'm working it'll keep recording. What's going on around me? Thanks to like nice lens. That's my plan for now Of course, I want to make a mobile later and I plan to attach legs for it to be wearable And then I can take them outside Yeah, that's you know a fun thing to do with wearable robots Yeah, but for right now. Yeah, this is just going to become my little assistant for my little Chaos that I have going on. That's really cool You know, the other thing is time lapses are kind of hard to do because you have to keep them still That might be neat to work make that work with the time lapse too So you could do a build but it'll follow you as you do it And then you just batch it out and then you've got this the speed up at the end Yeah, it's very it's really hard people don't talk about it much I might go into it But it's really hard to remember to turn on the camera when you're doing stuff Because I get so involved in the project and I'll get so far in it and then realize I have nothing recorded. Yeah Yeah, I forget to eat or do bio things and I'm just like, oh, I haven't eaten in a day Because I've been busy on stuff. So You need that matrix tube that goes into your throat and feeds you. That'll be next. I will thank you Jay Thank you so much. Good to see you. Happy new year and look forward to all the great projects you're doing and more and thanks DigiKey for Working with Jay and getting all his cool projects out there. Thank you Next up Joey, congratulations on your successful crowd supply. Tell us all about what happened. We are we're we're backers Amazing. Thank you so much. Um, yeah, it's it's uh the sensor watch well gadget I've been working on for a little about about a year now and Yeah, it's a I think the last time I think I brought it on it was just a little You know, I think I've gotten the LCD to work and it was displaying a green LED and it was kind of basic Now it's doing a lot more things and yeah, the the crowd supply campaign We put it up there and in 23 hours it got Almost 300 people back that it was it's amazing To I guess people watching you do this and so they've been like excited, you know, you've been marketing it for a year You know, yeah, someone's talking to me about this today like it's like I'm marketing it But I'm just kind of sharing my process and I realized the kind of folks who are into this are just into the sharing of the process You know, yeah They want to be part of what you're doing because you look like you're having a lot of fun One time we said when someone asked what Adafruit does because they're like you just do a bunch of documentation But I don't think you do marketing and we said good information is Advertising and I think you told a story with the beginning middle and now there's something that people can do to participate Have been following this along so congratulations. We always tell folks just start a blog Post up photos on social media, but just make sure you tell the story working in stealth mode. Doesn't make sense Yeah, you know a lot can happen too. You never know for sure for sure I Was gonna show a couple of things that it can do if you Yeah, let's do it. I got a screen share here. Yep So one of the things I'm really stoked about is This is the one I'm doing is a battery test So this has been running for over two months now and in this kind of low-power mode We're just ticking and talking it it's consuming under 10 micro amps of power. Wow So it's really low power and we got a little coin cell in here. So I'm gonna wake it up. I pressing here and then you've got your Temperature sensor. So this is showing the live temperature. It's getting warmer because I'm holding on to it And it's a you know, my fingers holding up And this is the number of days in the battery test and Then I had this I just got some other stuff that we've been working on so now there's a couple of people who have beta boards out there and Let's get here. Well, first of all the world clock. I've had the James was based telescope on my mind so I put Goldstone Madrid and Canoe vera the three places where we have the deep space network Oh, can you put in Mars soul days because that's always fun. I'm working on that But they're gonna be so happy so stoked right Yeah, I want to get that ported over I did it in an old version of the watch But I want to make it make it better and bring it in this time. So definitely in on the on the horizon You got a stopwatch and a countdown that Wesley Ellis did and he's a backer who's playing a beta and then this is just cool It's the two-factor authentication thing. It's counting down a two-factor code just a demo and not my real No, I've already hacked into your Gmail that I would use that every day because I'm constantly getting pinged on my two-factor So I just wanted to kind of share like some of the excitement that I had for and I'm just so grateful for everyone who's back thing and Yeah, just Really stoked. I love it. I thought it's just like the hack in these watches. It's so fun Yeah, and we gotta get circuit Python running on it too. Of course gotta happen And then for the folks who've fallen along for a while Joey won a hackaday contest and it was right before the pandemic started and we're going to make you're known for your e-Ink open-source ebook reader. So Yeah, we're still gonna do it. I'm hoping because we're soon gonna run out of people that can get COVID it seems I Hope maybe this summer we could do that too Or maybe in the spring now would be great to to hang out and we'll definitely be on time Because we'll have these watches that you're definitely Time where each other needs to show up at places. Oh, can you do I'm gonna get a watch Can you also add like a Pomodoro timer thing because that I need to remember to get I feel like Like once we get hard over people's hands people are stoked about writing code for like stuff We're people have asked about a Pomodoro and I'm like What's it coded in is it Arduino or is it it's just plain old see see it's see with a make file So yeah, okay. Well if you're a GCC is is good to go and then yeah Yeah, I've got a little framework called movement and it's it's it's kind of an easy way Just to add a watch face into the into the mix. So Interesting you might be able to add Arduino support or somebody else could I mean like we've got samd and you know You just it was very it might just work. It might might work Yeah, but I'm really stoked about circuit Python. It feels like it's just so close, you know How do you just report? How do you connect to it the watch itself? I don't have a blank board on me, but it the board itself plugs directly into a USB cord And then put it back in so yeah, you can't plug it in from the outside. So just have to take it apart Right exactly. All right. Well, thank you. Bye Joey. Well, congrats. Yeah, and as we see your updates and more We'll retweet them or hit like or wherever we see them. We'll hope get the word out and congratulations once again Thank you again. Hi nice work. Yeah. We go back this Disclats apply right next. I'm gonna Pedro. What you got going on this week? Hey, what the folks? Hey? Yeah, so this week We had a little pretty pretty case for the for the QDPI use p32 s2 Shout out to Brent because he kind of wanted this he asked to last week if we had a case for the QDPI like a generic generic Multi-purpose one we didn't so we figured okay cool We can make a QDPI case for this week But how do we make it so that you can add different stem of sensors to it? So I came up with these little vents that can be used as like mounting rails So I have a little a ht-20 stem of sensor here It's got the temperature and humidity and we just have it plugged in with a little stem of QT cable and it works pretty well I also have some tabs on the side so folks want to attach this for different surface I thought it'd be fun to add like a little like little thing here little I don't know tag I guess kind of like those the products. Yeah Hang tab hang tab there you go. That's called sombrero tags Are they really? I don't know if you're cool. I learned something. I learned something in it The the top has also these These sort of rails and I figured well what kind of things I could put on there and you can feel a lot of stuff in here So here have the little OLED stem of display and a little rotary encoder So we kind of fun to add different things to the to the top there and just with a couple screws and the stand-ups But yeah, the QDPI just snap fits into this little built-in holder And I'm hoping to do a library on how you can kind of count this off in different in different ways But yeah, this is kind of a neat way to get It's nice and it's all parametric too so folks want to edit the dimensions of it It's not too hard to do so so that's this week's Kind of quick 3d print a little case for the QDPI and it should fit all the QDPIs because we have quite a few of them now They're all the same size. Yeah, they're all the same size We'll show these videos on ask an engineer and Right now. We're still working out the name for the add-ons Right now. We're calling it BFF's best friends forever We also we're thinking of nuggets and some people suggested sprinkles and other things Mullet was one of the suggestions as well, but anyways, it'll be interesting to see what ecosystem That comes out of this and anyone can build things for so thanks for making making something already for people to Sure store and share Alright, alright. We'll see you guys next week. Okay, JP. How are you? Hey? I'm doing well I'm excited about Joey's thing because I have a Cassio watch. It's ready for his board and it's finally gonna come true I'm finally gonna get to use swatch beats time. Yes. Remember that I'm gonna JP for a while. I think every year somehow some way we make a joke Yeah Thanks, and and many other reasons to want that so that's that's very cool So what I want to show today's the stand been working on if you can share my Screen there. Yeah, this is my arcade button and joystick Piano Cade remake which is based on a project from maybe eight years ago. That was a synthesizer this one's a synth Using the feather M4 in the audio library as well as MIDI classic MIDI and USB MIDI out on it And the way I have it set up right now I'm using the buttons to play an arpeggio which is kind of a chord played one note at a time And I can increase or decrease the rate of the arpeggio with the joystick and I could also go up and down Octaves with it right now and this code is gonna gonna change as I go But if you can hear this I'm gonna play a little demo of it doing its thing Get a little faster Finish him There you go, so on Castlevania feels it does yeah arpeggios are the best and and so I think Some things I'm gonna be doing with it. I've got this is sort of my my temporary case I'm working on a cooler case right now, but it's probably gonna be this laser cut acrylic style I've got three buttons on the front that are just function buttons that right now I just have two of them switching waveforms, but those could be to pick different patterns that you play So maybe one note plays a whole pattern choose holding or not holding that pattern And then you can just kind of one finger go and pick cool patterns and those could be stuff like here's a Castlevania pattern Here's a Zelda pattern and so on and I think I'll keep the joystick function the way it is because I really like that It's a lot of fun to be able to go up through the Through the It's kind of the eng v mom steam mode for all you death metal guitar players with arcade buttons So that's what I'm working on and tomorrow I'll be showing some of the design process I've been using on building the case I got some cool new acrylic in that I'll be cutting tonight into a slightly Better pattern even better And if you want to come by to the show, I will I'll be showing off that process Yeah, and thank you JP for hosting and no Pedro did a couple times and you did as well Thanks, we were staying care of some ate a fruit stuff sure all safe and Just you know keeping the business going getting parts in stuff But I love that you're doing that. So happy to help. Yeah. Yeah, this business going I'm very Excited about all the stuff we're gonna do together in 2022. Yeah, me too. Thank you so much guys. All right. See you speaking of Jeff always delivers it delightful. Jeff. What are you doing this week? Well, as you may have seen from Lamar's recent video I hit that it's full of stars and I understand everything moment with floppy drives But I something a little different than the Moore's video to show you and that is I'm gonna read Five and a quarter inch floppy. No way so I Got a little bit of a gag program here that acts a little bit like DOS, but let's go ahead and mount that floppy And this is you can see our seeking there That's in circuit Python. This is this is really circuit Python that part is not a joke. Okay Look like it looks like DOS. It just looks like DOS. Yeah, so cool. So all right directory listing I like it implement DOS Yeah, and I noticed there's a read me file, so let's open that guy up Yeah, it's like actually the real read me is on disc two I thought that was funny. Yeah So, yeah, that's about it, but I haven't a lot of fun with the floppy drives and Working next just kind of getting that to come at you know getting the pull request actually ready for circuit Python and Yeah, bring in that functionality in but if you go find the right branches of this and that in my github You really can read and now the floppy with circuit Python. Yeah What's fascinating is we you know Jepburn and I for folks watching, you know It was you know, it's one of those jokes where you're like well, you know when you do it should just work And I was like well like after you can read sectors you should just be able to treat it like you know an SD card It's the same format. It's fat 12 and we have native support and what's funny was like well It really did work and I was like I was kind of kidding Well, you know, it was a nice relief after a whole weekend of just marinating in the MFM. Yeah MFM is weird But it's you know, it's interesting about likes scuzzy and mass storage and floppy disks Is that the way we store data has not significantly changed in like 40 years like we pretty much do the same thing? It's just we we fake it now. We're like well, you know SD cards have sectors, but it's like those are fake But it doesn't matter if they're 512 bytes and they will be forever because Five to quarter would floppy is decided on five full bites. Yeah, and three-and-a-half inch So we have a bunch of stuff going on that will continue to Share as we do it, but folks were asking And now we can show them this video Jeff. They're like, are you gonna do this? Okay, what about these drives? What about that and here we are? Yep So the five and a quarter drive just had to change the number of sectors per track from 19 to from 18 to 15 And it worked. It was really a pleasant experience. So happy about that. Yeah I mean like the sugar interface is I mean like I you know I have a sugar 801 that I'm repairing and bringing back to life and and that's a really ancient beast we're talking about from like, you know 70s and It has the same interface as yeah, this modern floppy. It's like they came up with like this idea I mean, it's FM. It's hard-sectored But the overall way you talk to these drives has not changed For sure. It's cool. All right. Thanks so much, Jeff. And as if people said in the chat everyone Seems to have a collection of five and a quarter just said they couldn't throw away But there's no way to get the data off and now you'll be able to do it Yeah, we're gonna we're gonna work on GCR and we're gonna get you know, lots of formats working and grease weasel We've got working. So we're gonna bring a you know true open source Multi-format floppy disk reader and I'm designing some hardware. It'll make it easy to Yeah, yeah, this feather design you put together really made hooking it up. Yeah Could revise it to add a shifter because I know people even though you don't need one I know people gonna freak if I don't have one. So I think I'm gonna just you know Add on surface mount on the bottom at at level shifters and you know make people happy. Yeah should work All right. Thank you, Jeff and I'll say it again Thank you for all the delightful things you've been delivering and I'm looking forward to a fantastic 2022 together We're trying it off kicking it off. Fantastic already. Yeah, this was great I had a really really it was like not one day was like two days because it was so much was going on And at the end of the night Lamar said you have to see this and just like oh my god And we filmed it and we published it. It seems like it was a long time ago, but it was just yesterday It's less than 12 hours ago Thanks, Jeff. All right. Night night. All right next up. Liz and then we'll go to Liz what you got going on Hey, how's it going? Um this week I got a guide going with um a passive mixer um So I've got two voices here So it's four inputs one output all stereo Um and guides it now and then the other thing I designed up was I got one of the pink feathers And I wanted to have like a little stand for it. So I just end up a quick little Uh kind of like L stand I put the ate a fruit logo at the bottom. So it's kind of embossed Oh, that's nice and sparkly Little holder goes well with your pink cutting board. Thank you. Yeah Yeah, so I got that on my desk. That's exactly the same shade of pink. It's a little creepy and the yellow Yeah, I didn't plan that And the yellow the mixer is the same color as the the line So it actually looks like some sort of like Martha Stewart like, you know, there's like staged photos Like everything matches. It's probably the most together I've ever been in my life. This is very instagram ready Nice. All right. All right. Well, thank you so much. Liz and uh, I'm so glad we got a chance to visit you in person Right before everything kind of got a little Uh squirrely on plain earth That was great timing. We got back and then, you know, obviously we wouldn't we probably wouldn't have uh If it was this week, we probably would have had to postpone But it was good to see you and I'm looking forward to all the stuff we're going to do Um this year. I'm also looking forward to it too. Yay. Okay. Let's take care and thanks for coming by All right, so we got through some of the it for folks and then we have let's see Come on people Hey, am I on Okay, I want to I want to I want to jump to the fun part, which is I built a little synthesizer But it's it's heavily populated with stuff from you guys. So I just want you to see I got your stereo decoder your your uh, lipo Not really in focus. Is it lipo thing? Yeah Uh, what else we got so it doesn't have to do anything at this point, right? It's just It serves as a and there's one of your little gain control amps. Yeah So here's the guy it's a little synthesizer and the only thing unusual about it. I guess is that it It has like a whistle interface. So You don't have to you just sort of whistle But you don't you don't blow you just sort of use your mouth like a whistle and you can control the pitch um, so it does a little it has a little um Microphone a speaker and it pulls your your mouth to see what frequency Is the natural resonant frequency? Yeah And that's how you control it. So I'll I'll try and see if this works. This is demo time. Yeah There you go. It was like the coolest thing I've ever seen. That is so cool. That is so cool So it's a little phase lock loop basically and looking for I don't know if you remember your, um Physics I guess there's high high school college physics They uh, there's a phase shift right at the resonant point of a Helmholtz resonator So it just looks for that And it locks on to that Uh, so it's you know, perfect for overcompensating for people who want to play an instrument, but Don't want to learn how an instrument is played So I love the elegant interface. It looks it looks really fun because you you know humans are like naturally Music making but then this kind of just enhances it's like a bicycle for your mouth. Yeah Thank you. I'll use that if you don't mind It's like a bicycle for your mouth unnecessary If folks want to find out about this or are you going to publish anything? Could they remake it? What uh, what's your plans with this? Yeah, so I got a website. Um, I've put up a bunch of stuff on git So it's muse electronic instruments.com. I've made a few of them I want to make a kit ultimately, but it's uh, turns out it's pretty complicated because you have to do Have to do some PID tuning and things like that to make it work I have a few for sale, but all the all the schematics and stuff are up um, and of course it's It's an eight of fruit design, you know, you just go buy your plug-in boards. It's got um The only thing that's really not I mean everything's purchased through you. I think the only thing you don't make is the teensy Yeah, we sell the teensy though. Yeah, we saw yeah. Yeah, I mean I bought it from you, but it's not blue I don't you know, we're talking about pink. It's it doesn't really match, right? It's okay. It's okay. I mean it's like we're like a rainbow coalition, you know And uh, Keith if you're selling these online email pt at adafruit.com. I'll do a blog post and uh Have a have a little spotlight on our blog about your oh, that'd be nice. Thanks. Yeah I'm kind of fascinated by this. It's a very it's it's an interesting and extremely hard Uh problem, you know, I remember we we had um or a quarter We got a recorder and we were trying to detect the resonant frequency And it was like much harder than we thought because recorder is not a pure tone instrument It actually has a bunch of harmonics and so we got pretty close, but it was you know It's it's interesting electronics versus the human ear and how we detect pitch and tone Um, you know what you learn grade school is not really true A lot of linearities and assumptions that we make so I think I'm going to check this out I'm fascinated by how you got it to work so well Yeah, well, I'm I'm sort of surprised it works as well as it does but Oh, I want one more thing. So I've gotten a I had an invitation to join a band So I uh, I hardened it up for uh for stage use Uh, let me see if I can get the here we go. Yeah, so it's got a hundred watt amp on it As one does yeah, you know, if you can't be musical you want what's your next? Your reference loud, right? Absolutely. I had an architecture that said if you're not good just paint big All right. Well, I gotta say, you know, I've got uh gain control it goes up to you know, 11 All right. Well, nice work. Thank you so much for coming. Thank you This was absolutely delightful come back and show anything anytime and uh, some folks put the link in the chat And it's called the zen flute and uh, let us know as you do more with this. Absolutely beautiful. Love it. Love it. Thanks All right. Thanks Keith. Thanks everybody. Well, what an amazing show. All right. That was a wonderful sandwich I know If you look at with all we had a lot of synthesizers, uh on this show Thanks everybody you bring in your musical instruments I think I think we need music to bring us together kicking off the new year. I know, uh, things are a little, uh stressful at the moment probably for a lot of people But there is a half an hour every week that we can come together and show and share the things We make together. Thank you so much everyone for uh joining us, uh And again, thanks for the folks that were hosting the shows. Uh, I've been looking forward to this For a while because we were like, let's get back on the show until, um So thank you everyone for coming by tonight. We'll see everybody on ask an engineer and we'll see you next week 7 30 p.m Eastern time Every Wednesday show until the longest running Show and tell of electronics in the world See you next week. All right. See you in a few minutes. Ask engineer
