 Pedro what is this? I wanted to do the drums. Hey everybody. Welcome to the Adderfruit show and tell this is a place where everybody shows Off their awesome DIY electronics projects, but it doesn't have to be just electronics It could be through your printing or wearables or arts and crafts or even retro tech We dig retro tech so let's go ahead and get started We'll give everybody like two minutes to go over your sweet projects and start off with Kevin from Digi-Key Who's got some awesome guys? How you doing? How you doing? So I want to talk about something Digi-Key just launched Do you mind pulling my screen down just for a second? I'd like to show you the picture okay so When you get cut tape strips from Digi-Key or from you know any manufacturer This is what it looks like you have no idea what's on this trip except little tiny Resistors capacitors diodes, whatever it is, but now Digi-Key just started launching this on Monday It's a free service that is just a part of this strip and it's going to display all this information on me It's going to print on here. It's going to print the lot number of the date code The manufacturer and then you can also incorporate. I know it's a little blurry. So I apologize for that But you can also incorporate different things like Whether it's your invoice number or your p.o. Number You can personalize it and then you get a really cute little Digi-Key logo on there And I do have the page pulled up and this page is just a little more information about it This is just a resource page about part tracing. What is it? What does it affect? And how can I get it added on to my parts? Which there's nothing really you need to do except if you want to personalize it in your checkout screen You will have the opportunity to personalize some of these cut tape We don't have this available for for all eight millimeter Parts at this point, but we are continually working hard to build this up and get more and more and more incorporate into this You know, if any of you have cut tape strips at home, you know, you know exactly what i'm talking about Once you lose the the bag for it. You're in trouble But now with this we have a good option for that you can keep these parts around for a long time And you can reorder them. You know what it is We're really excited about it. I hope you guys are too. Yeah, for sure. No, that's awesome We were discussing too. You could maybe add like custom glyphs or something if you have that in your part number Yeah, um, so it's going to display things like the digi-key part number the manufactured part number And then like if you add something to your invoice number or Uh, your purchase order number, it's going to display that on there as well So you can get creative with this if you really want to yeah Yeah No, this is really great. Especially if you have like custom pid numbers. I know they do that a lot in the office So it's gonna be great Yeah, and you know, you know how small some of these 0402 parts get you you don't even know if it's a instructor pastor unless you get in there and try to test it Oh, yeah, but we have this on here and this should hopefully help like this one is a SMD resistor 4.7k at 1% Wow So very cool All right, we're really excited about this Anybody who wants to see it, uh, the website is digi-key.com slash part dash tracing Excellent Check it out. All right. Thanks Kevin. Yeah, you bet. Thanks guys. All right. We'll check in with you Thank you. Thanks. All right next up. We're gonna check in with jp Hey jp. Hey guys, can you hear me? Yeah, I'm good awesome great I always like to check that because I have issues with my audio sometimes So I wanted to show a couple things actually so I have been working with our very own foamy guy community member foamy guy on a Sort of a stream deck alternate. I'm calling touch deck. It is a feather nrf 52 no, it's a feather rp 2040 and a three and a half inch tft feather wing touch tft feather wing And I'm gonna go ahead and show you what that looks like right here so this is the the feather wing and the feather inside of a little case that I designed and 3d printed and Foamy guy has helped me create some really nice software that allows us to Create different buttons that are touch buttons that will send usb hid commands consumer control codes Just type things out for you and so on And the one of the really neat things about it is that it does so with a concept of layers similar to a stream deck so I can Click to a completely different layerset. This is some youtube controls here Um, and that gives me things like play and pause skip forward go back To the previous one in a playlist my favorite ones are going full screen in and out of full screen as well as Increasing the speed of a video kind of jumping it up in those 25 percent increments and then if we take a look at This discord set that I have here. I'm going to go ahead and show an overlay of my discord Let me move some stuff so you can see a little better So if you watch my discord right now If I want to type in any of the ate a fruit emojis I can just touch a button And bam it put it up there for me And so i'm going to be like the fastest gun in the west for typing in ate a fruit emojis now Because I have them laid out right here on my keyboard What you might notice in fact when i'm when i'm pressing these buttons if you look at that overlay of the Discord it's going to type something out real quick. You can kind of just detect colon minerva colon actually gets typed out real fast when I do this it's uh there goes You kind of saw that real briefly And that's what makes this possible with the uh pretty much with all of these these are just uh usb Either hid keys keystrokes or key combos being set or using the layout section of the circuit python Hid we can type in full phrases that are in quotes and hit return on so This is coming along. I've been developing these icons for them and Uh We've got a really nice config file that allows you to change what these buttons do and add your own You can see i've got kind of a test one Here that's just some blanks and we're going to be working on speeding it up So uh, I've actually got some fairly large uh icon sizes I'm going to I haven't indexed them yet So the the file size will go down about a third of the size and we might get them loading much much quicker And and foamy guy has some ideas on that so that's my project come on tomorrow to take a look at Some of that some of how I built the thing and the case I have some further explorations there and I'll also be uh, Entering a new project that involves uh, that gizmo right there, which is that Pull this out of the way Which is that raspberry pi 400 and my little deck controller board And it's let me get my hands out of the way and it's gonna Involve a synthesizer of sorts. So let's tune into martin. I showed it check that out Um, excellent. So cool. Excellent jp. Thank you. We'll see you tomorrow All right next up we're going to check in with jeff. You want to get ready? Uh, here we go Hello y'all Hey, so, um, I had a guide go live in the eight of fruit learn system last week Showing how to do Circus sculpture. So this is a really basic one On a gemma and when you touch it the led cycles through the colors um, so I've been playing with circuit sculpture for about two months now and I like the way that it kind of makes Your circuits Bigger and more real. So here's another one that I've done I may have shown this on show until kind of an arch theme with neopixels And then maybe sometime in the future we'll do a more complicated guide on this guy Which is kind of the most complicated thing I've done But check out the guide if you're interested in kind of creating these 3d extensions of circuits They can do things they can just be art and uh After a while you start to pick up on the techniques and and get better at doing it because You know just from here where everything's a little bit wonky to here where the shapes are really what I intended Uh, it's it's been fun growing and you know, if you want to come along with me, uh Yeah, it would be fun to have you how cool. Yeah, definitely check out the guide everyone. It's awesome. Thanks Jeff. Thank you Have a good one. You too All right next up we uh, we're gonna check in with scott Scott, I think you have an unboxing right? Hello. I do so I I got a package today Uh, and I got the goodie bag for the open hardware summit as of last year that was canceled right as the pandemic started Um, I know these were trapped in like somebody's office at nyu for a while So I was super happy to see them I didn't realize they had actually gotten them out of the office and that sent them out And the thing I was most excited about what actually comes in this Spark fun box because they sponsored it and built it Uh, but it's a it's a watch that um, let's see alex It says it says on the watch. So there's there's the front side of it And it's designed by alex camillo Camillo and michael welling so congrats to them. Uh, but I believe it's running circuit python, which is super neat Um, and I haven't actually plugged it in yet, but there's there's also this back So I think I'm supposed to assemble One on top of the other and then there's these slots in the back For a watch band And they're the sponsors. So thank you to all those folks for helping put those together And they actually do come in the box with um, some standoffs and a screwdriver for it as well. So um, I'm about to start working on beli sorts of stuff in circuit python again So I'm very excited to see this Um, have a watch that you can have on your wrist and program from your phone is is the goal the long-term goal Or hopefully the the goal this year Yeah Excellent and did it come with a watch band? Uh, no Although, you know, it might have I haven't looked through the whole bag Okay, uh, so it might have I haven't yeah, there's lots of what else is in there. I don't know I'm gonna say maybe I don't know how many more people you have but okay. Maybe we'll save it. We'll do it as a cliffhanger. Oh, that's a cool hoodie I got a hoodie Or a hat and it's like lined, which is nice um Another getting to blinky sort of thing with after dark from osh park Um, let me just see here If there's a there's a brain Hmm open bci I think it's squishy. Is it squishy? Oh, yeah, it's squishy Um, I don't know. I don't see a watch band Oh, there's like a make You just like a cutting up the bag maybe you can Oh Yeah, I could use the bag for it. I don't know. There's all sorts of stuff. There's a ruler Is that a oh, okay. Hey, it's like it's metal, which is nice. Yeah It's uh for pinocchio, I guess They do laser cuttings. So this is probably a nice service. Yeah, let's be from them Digi key Like notebook Save the rest for uh, maybe maybe your stream on friday Yeah, we'll see I got some other stuff to show on friday as well. Oh, okay. All right. Um But yeah stickers and stuff that looks about it I don't have to show it all off. I think like the thing that runs circuit python is definitely the thing that's most Most interesting to me. Totally. Uh, but it's cool to finally get my hands on it Yeah, yeah All right, thanks for letting me Cheers. Thank you. All right next up. We're uh, going to check in with brant Brant's got some whippersnapper news. Hey guys. Hey, you can hear me, right? Yes. Okay, great because obs just decided to crash everything But it's back. So i'll share um my obs window because the virtual camera decided not to work anymore Uh, you can see that right? Yep Okay, cool. So um Whippersnapper is something that we've like the adafruit.io team has been working on So this is like a staging server. So we're not out like this feature hasn't been pushed anything yet So if you click on whippersnapper at the top Um, you can see boards uh that you've previously connected to So a bunch of different types of boards, uh metro m4. So all of these Are internet capable boards except for the mcp, which I used to test locally But I have a pie portal over here and I'll briefly show you What getting to blink looks like so I connected it over power um, I have to add like a status led but To the firmware, but it connects to adafruit.io and it checks in with it And when it finishes checking in um It will do a drop down So it doesn't matter which board you put this firmware on It will automatically tell adafruit.io. Hey, I have a pie portal. Wow. So call it show and tell And then on the device page, you'll give like a little window It'll take you to learn guide for this device You can also add a new component and we haven't fully obviously haven't fully fleshed this out yet Um digital input is next so this button is not ready yet And that's probably what I'll show next time. But for output We can grab an led So this drop down if you're checking like if you checked in Like a feather m4 or something it would show all of the pinouts for the feather m4 This is the pie portal. It only shows the pinouts for the pie portal So if we select the 13 led we create a component it'll automatically show up And we can turn the component from here on and off Yes, wow that's done over mqtt So this is all done over adafruit.io and it also creates a new feed for the component So like this builds on top of adafruit.io So um once sensors are working on this it's going to be really really powerful But this is the first step to getting there Wow, amazing. It's like plug-and-play configuration of most boards Yeah, no code. Uh, wow the main thing Oh amazing. I can't wait for this one. Holy crap. Yeah, I can't wait either All right, all done. That's all I have to show. Yeah, definitely come back with more And if uh, uh, you started doing like a developer notes on youtube too So, uh, definitely watch out for the blog posts. So when those come out or subscribe to the youtube channel You can see uh when all those are uploaded Super awesome. Thanks, Brett Thanks. All right. All right, Brett All right, next we're gonna check in with, um, Micah All right Oh your microphone Hi, so sorry about that. Um, I've been working on a project for my sister's birthday. She turned 16 today Cool. So I've it's gone through several different completely different ideas and iterations So the first one was maybe I would do something with a matrix portal or something Could have been cool, but matrix portals are always out of stock and um uh Second one is maybe I could do like some mood lighting with neopixels But that was kind of going to get complicated Just to have like little individual units everywhere So I ended up deciding and I'm in her room right now. So I ended up deciding on this Oh like a skylight, right? Is that what it's called? This is called project constellation So, um, the central V shape is actually the constellation Pisces So Sorry, it's not centered It's okay. Um, and that's her zodiac sign so Um, and there's 16 stars in the background. So it's symbolic and I managed to get it working with The rf the standalone rf latching um receiver Okay, this little key fob sweet and pretty much Pretty much everything is from ate a fruit and My mom helped me solder a lot of it because nice. Uh, there's a lot of careful smd soldering. Hi Hey Um, those little lights were hard to solder they were tricky. Oh my god. Yeah Yeah, they're the button pcb neopixels Okay, and they would have been easy if we'd used stranded wire Oh That's for the next one. Yeah Excellent. Well, well done. That is very awesome. Oh, that's excellent It's always the best one to make something for someone and even better with like your friends or family members No, you just inspired me to want to do one in my son's room. That's awesome. Thanks. So what's your share? I like it. Bye. Thanks. Bye. Bye Okay, next up we're going to check in with mark gambler Hey mark. Hi So this is just a start of a project I've had a problem of a lot of delivery drivers end up driving right past my house to where my house numbers are Situated you don't see them until you're past Which becomes a problem. Uh, so I've decided I wanted to put light up Numbers on my house. So I've just started in 3d printed. Um Just a sort of model of it so far I just found it. It's a lot easier when you can actually start holding something to see how you want to flesh out the design from there Even with the Oh, sorry continue. Yeah, which is the best part about 3d printing is it Matter of minutes here a couple hours. You have something you can start looking at and Seeing how it's going to look like in the real world So the idea will be to fill it with neopixels. I'm not quite sure what to drive it with yet um, I keep Wondering if I should make it wi-fi enabled just because I can but Or just use a cutie pie or one of the new rp 2040 feathers But uh, I've got the next two weeks off. So now I've got something to occupy my time at least Yeah, no What I was going to say is that even if you have all your measurements and like you have like a tape measure And you're like, okay, it's this big you print it out. You there's always like, you know The crevices or like where the two curves it's like, oh, I didn't think about fitting it here or you know Stuff like that. So yeah Definitely printing out even when you know, you have all your measurements You'll still figure out like some changes you have to do for it. So yeah Yeah, real life always ends again in a way. Yeah Awesome. So thanks for sharing Yeah, come on next week for progress I will do Excellent. Thanks mark Thanks Okay, next up we're going to check in with michael All right. Hello, michael. Hey michael. Hi. Can you guys hear me? Yep? You're good. Awesome. So yeah, I um Have been working on this crazy project Uh starting in october of last year and they uses this iridium rock seven rock block modem Um, and it's a I'm trying to make a satellite phone um, like just a messenger and It's it's been crazy. So let me show you some of the photos of Like what looked like about a week ago um And that's the insides of it. It's a little bit crazy. I had to redo all this though So this is what it looks like right now. It's uh, this was the original Revision two that's what you guys saw on the images. I designed These files on tinkercad like using tinkercad um, and then yeah, so Basically the problem that I had was with the screen Originally, um, I was using this like transparent OLED from spark fun And I had it like angled like this and that put a lot of stress on the uh on the ribbon. So I had I had to redesign it. So last night. I actually redesigned this little like retainer thing for it um, so it won't mess that thing up um, and this entire project's being powered off the uh stomach Qt pie with a um, the like the backpack charging thing um, and then a boost converter and all that stuff. So Oh Great job. Yeah, that's awesome. Come back on the progress. That's definitely where I am right now. We're have to rewire everything Thanks for sharing Michael. All right. Thank you. All right next up. We're gonna check in with mojit All right. Hey, hey, can you guys hear me? Yeah, perfect. Yeah Yeah, good to see you all. Uh, first of all, props to everybody's project so far. Those are really rad. Yeah, they're awesome I've been hacking with a couple of different things lately. I've gotten obsessed with the tomatones Is blaming my friend Chloe on this one. Uh, if you've ever seen these they're Oh freaking cool Yeah, it's so um Yeah, start off with one and then I'm at four now but uh So I I got this one There was a smaller one. I wanted to take it apart and I found that I was curious like How much smarts are going on in here and uh, it is just like the base circuit is just Takes the slide value Uh, the resistance and pumps it through the little speaker so I started off trying to run it with an arduino and using this uh, like a max 98357 uh a amp i2s amp But like it's tricky to do any sort of life synthesis with i2s the code's a little more tricky than I like so uh That evolved into just making it okay I'll just make it run a buzzer taking the direct value Then uh, that evolved into turning it into a midi controller. So actually I was gonna say it always leads me It's really hard to do it in a way that's not haunting. Um So that one turned into midi control and then I ordered A deluxe I ordered a deluxe in black first and uh, it came messed up like the this is actually you can see the The slide sensor that's inside that goes normally on the neck here. Uh, so it's it's pretty cool it's got a you know layers of like dielectric and and whatnot, but uh Then uh, it was just stuck floating like the top value was constantly playing. So I opened it up And I think subconsciously I wanted to have one that I could tear apart and get the second one So I shorted it and made it worse by mistake. So I just got it at all uh, so For this one, this is like the body of it when you take the mask off Um, I've cut some space in there so I can put in a raspberry pi zero with the the speaker hat So, uh, I'm gonna turn this into a um Like a live synth with sonic pi running on board so I can remotely change the scripts and I have to take the value Okay And then yeah, then I have the the large one still I've also been doing so I now work for sorcom i o or sorcom iot so Uh, like the cellular iot Okay So one of my recent projects that I've been hacking with is taking the Jetson nano the two gigabyte version with the wave share jetbot platform And connecting it with the sorcom onyx usb modem so, um, I haven't quite figured out what I'm going to do with that yet, but it's kind of great like, uh I can directly in the um jupyter notebooks write a python script that Sends messages out to sorcom so I'm going to try to do some like if it detects like a cat or something It lets me know where the cat is And uh, if it's all right if I share my screen I don't want to take up too much time Yeah, you got it. Yeah, you got like like six minutes Well, do you get like a minute? Let's go ahead and save it for like next week then yeah I just wanted to share that uh, yeah, I got I published a new hackster guide on how to Oh, okay. Excellent. So uh, sweet. I'm very interested. Uh, my handle's right there and I have something linked online. Oh, yeah Yeah, please post the link Thanks. Thank you. Thanks guys Sweet next up. We're going to check in with Andrew if you want to take, um, maybe three minutes We can get through everybody Here we go Andrew. Hello Hey, quick quick demo here. What I want to show off is the uh, the mighty own geiger kit it's the uh In the shop. It's a do-it-yourself geiger counter Um, I've got it muted right now ticks off, um Just normal radiation. Uh, I've hooked up the ftdi cable and been streaming some stuff Uh, interesting fine. However, I uh, I'm also a photographer and I discovered that uh, one of my lenses is Not very safe. So in this quick demonstration, I'll show you the uh The super takamur It's kind of nuts Oh, holy crap. What what lens is that? That's the super takamur. I'm sorry. Where am I? The back of the lens is super hot. Holy crap. It's like, uh Over a thousand millisieverts per hour Uh, it's considered dangerous and uh, I'm gonna get rid of the lens But anyway, I was uh, just happy to know that this thing is not going to be under my bed or near my family Wow makes me want to get one to check all our lenses Yeah, thank you for sharing that what no problem the 10-year anniversary of the fukushima and I just Thought maybe to do some environmental sensing but turns out. Yeah, you can use it for other things. But anyway Fun demo. Thank you everyone The more you know First yes And second and third thing. All right, I guess we're gonna end the show with liz if uh, Let's say that's Liz. You got the you got the floor. Hey, how's it going? So last week I was talking about I'm working on the sailor moon locket prop Um, so right now I'm working on the case in CAD. Um, and before printing out like the whole thing I like to print out like little test prints Um, so I'm gonna be having a little like um button inserts to Actuate the buttons from the back So I did test print to show that could hit the buttons on circle playgrounds Um, and then the other one was circular snap bits. I referenced a layer by layer Um, I'm sure that will work Um, and this part will actually go on top here And then there's a dome that covers up to make this look like a circle Oh, I've been working on Awesome sweet. Yeah, I love the the shape for the um for the little button pressers. Mm-hmm This little reliefs Um, definitely want to play with that more in the future. Yeah for sure Very cool. Thanks so much. Yeah All right, I think that's gonna do it for the show. Uh, Yeah Everybody who showed off all those awesome projects. Yeah, but don't go anywhere. Stay tuned. We have ask an engineer coming up in like three minutes Yeah, you got it Bye folks. Thanks for joining See you next week
