 All right, lady. What is this? Hey everybody and welcome to show and tell. It's me Lady Aida with me is Mr. Lady Aida We're here at the Aida Food Factory not a green screen. This is the fact that we do all of our manufacturing And kidding and and assembly and coding and stuff Nobody else is here. It's just us in the factory. So we're maskless because we're Vaccinating we live together, but why you're bored of us what you want to see is everybody from the community Come by and show them what they're working on. So we're gonna kick it off with Kevin from Digi key What are you up to Kevin? Hey guys, how are you doing? How's everybody good? Good good So just a quick thing that I've been working on I've been doing a lot more 3d printing lately And I've learned a thing or ten from Noah and Pedro. They seem to know everything which is great So make sure and watch their 3d hangouts But I did start using octoprint this week or not this week like last week and started playing around with it and this week I added the Aida Fruit Neopixel strip to it, which is a Deal breaker because I kept shutting the light off in my office when I was when I would leave and I'm trying to do time-lapse videos and It would go dark. So the time-lapse didn't turn out very well so anyway being able to use octoprint and Directly integrate it with the Aida Fruit Neopixel strip has been Really great. It's been a lot of a lot of fun to get its work with a Raspberry Pi and very interesting and I've really enjoyed it It must be fun It must be fun that you can just like go to the Digikey factory and pick up Neopixels. Whatever you want Oh, yeah, it's a Digikey factories right across town and it you know, it's like a candy store for So yeah, I love it. It's been great Next thing I'm gonna do is I'm gonna try and figure out with one of the many thousands of Aida Fruit boards and Integrate a sensor to it so it'll sense the light when I turn the light off and I'll automatically turn white LEDs on Good idea. That's right. We just got We have one of the new iOS devices that has a LiDAR Oh, yeah on it And so I haven't seen a lot of examples yet, but we're gonna figure out like how can you scan something in real life? Get the file out. There's apps that do that and then print it. So Oh, that's really cool. Yeah, we'll try to do that. We'll let you know how it works out It'll be on the show until sounds good Thanks guys take care Next up it's Scott Scott's map. Hello, so Unrelated to circuit python. I don't know if I showed this or not, but this is fiber deserts net It's a project. I've been working on in my evenings for I don't know a few weeks now The idea is that it should help find areas in the US where people don't have fiber internet They have cable or they even have DSL. So this is kind of the current version of it and The red areas are the places that people don't have fiber and the more red it is with density So this is kind of what I was playing around with But it doesn't have it just has Washington here is what I did and I had to switch tech So I've got this new demo. This is New York and I don't have the broadband data here yet But you can see that I'm able to do the same like hover over all of the regions. It's so nice and It changes the regions depending on your zoom level So it'll do counties and then as you get zoom closer You'll do like census tracks and then census blocks and census blocks are the units that the FCC reports all this stuff and that's kind of why it's centered like that and I just wanted to do a shout-out because the project that I'm switching to you for this is actually I think called data set spelled like cassette. So d a t a s e t t e It's a Python project and it it blurs the line between like static hosting and databases where you ship a SQLite database with your code and You can have like as many copies of that as you want And it has these cool properties that it has this default interface where you can actually just do SQL from the databases that are running on your server So it's a really neat project. I wanted to show it off for folks And I'm adding some extensions that handle all of the all of this like GISC data to it So next step is to figure out how to get the side panel so you can see all the data about a particular block and then also like Joining it in and styling it so you can find the areas that are most interesting All right. Well, just like the last round of municipal projects keep coming back and showing Some of the progress and then you're gonna be doing your deep dive sort of Python stuff. Yep Yeah, I've been making lots of Progress on the workflow stuff. It's not quite showable, but I'll definitely show it next week. Hopefully fully functioning Even if it's just a little duct duct tape I love the metro data analysis I love when people are like I want this data and like if you think about it 20 years ago There was no way to get any information like this about the your city-state country now It's like it's cool. It's like getting GIS data getting these agencies to to publish the data in a way that can use it They know that if they just give you the data somebody else is gonna make that right and for like the broadband stuff like there's been a couple of rounds already of like rural funds and They've not been spent that well in my opinion because they're spent usually on DSL And like people are getting DSL in 2020, which is just absurd to me So that's one of the things I want to highlight here is like oh, you're in this area And so and so got paid twenty five hundred dollars a household or a person to run you 10 megabits down and one up DSL like that you're sharing with like everybody else on your block, right? Yeah, so like instead I think my opinion is that we should just pay for fiber to folks because that's a better long long-term investment And that's why it's fiber desert. It's not broadband Okay, so that makes sense Data set and sequel light fans in the chat. So yeah up some links in there and then we'll do catch up with you on Friday, right? Oh, yeah And then the two weeks after that I will not be streaming because I'm going on vacation. So just a heads up for folks. Yay Hey, all right. Thank you so much. Let's go to no Pedro. No Pedro. What you got going on this week? Hey folks Hey, yeah, so we wanted to show a prototype type of something that Dylan came up with so she had this cool Jeopardy game Brennan the CPV Because I love our many remember from reading rainbow is gonna be hosting July 26th through Internet say 26 to 30th. So we wanted to make sure we You know ready for that So there's a controller here that you push to get the I guess the players ready And there'll be three of these I can play along so you do whatever question We'll just watch it during the show do a little shout out that we do and then you know You get the answer and a little lot the stem speaker handles us some sound effects, and then you can reset that like that And then have the next player here the next question and go up So all bunch of wires, but it's all gonna fit within this little three printed box We have the CPV inside here And then the stem of speaker will go on the bottom and then this guy's just that fits on top with the diffusion The color like whatever player you'll have different colors on there And that is a prototyping and then I wanted to show off some key cap stuff since Yeah real quick just want to share I milled some of these key caps There's a 3d printed lemon cat lemon pad from a couple weeks ago So just wanted to print some of these key caps sorry mill some of these key caps in this hard wood So we got a couple of these really nice key caps in the shop So I've been using this as like a reference point to see like how can I mill the stem? That's really the most important piece about it hard to focus, but whatever what you're gonna do So I did do that and I ran through some some failures here So this design didn't end up working too well. So I kind of reworked it. So that's more of an enclosed bit here See that I'm sorry about the focus, but It were it ended up working out pretty well I also want to do some like multi material Maybe it can mill this out of some some HDPE or some aluminum and kind of press fit in there But so far it seems to be working pretty good And then we have some other kind of different shape ideas because like the whole point was to kind of make something that wasn't a square Yeah, so I've seen see milling learning learning some different things. Okay. Cool. And folks tune in to your show This couple has the longest running 3d printing show on the internet So you got it. I'll take 3d hangouts for 300 Thanks Let's go to know let's go to John Park John Park. What's going on? Hey, hello, so I also have some yeah, I got some bongo cat going on here I showed this yesterday and and you might be showing a clip later I don't know but the thing I'm showing on here is actually this feather wing which is a Two key switch feather wing and one of the things I want to point out is that since I was using this yesterday and I was actually knocking keys off when I was using it. I 3d printed a little switch plate and Essentially the switches click into this and they give each other a little bit of stability You usually keyboards have these a metal stamped plate or something like that so I've added that here and then I've also been working on a Fun little remake of a popular project in the mechanical keyboard community That's called the 2% milk and it's a two two key macro pad and it's in a milk carton So I designed my own version of that model that fits a feather and our feather wings So this one I've got our in our 52 840 in there a little space for USB a little space for reset And then a couple of keys and you can see there again. I've got a key plate holding those switches in nicely so they'll Be nice and stable nice and solid as you use them They won't wiggle out because these are socketed so these switches are sitting in a little socket They're not soldered in and then the third thing Of my of my keyboard stuff going on today's I showed this really huge novelty Key cap and key and I've modeled and printed a little stand for it here So we can still sort of see its innards and I just got in today some of our eight millimeter Diffused neopixels and I hooked that up to it. So now I can do some lighting effects when you press it This one's Not doing anything right now. It's not gonna like shut off my computer which is good I've disabled the USB output, but normally we can use this to output USB And now I can also do some cool lighting effects with that big juicy neopixel That's what I got going on. It's so chunky. We'll be playing some of your videos tonight I'm asking engineer and then tomorrow's JP's workshop and more. Yeah, come on by for more fun. Okay, clicky click click John Let's go to your dragon. Oh, hello there the eyes have it I thought you know, I thought my eye days were behind me like we were done But actually on the weekend I had some questions from someone who like actually makes like monster stuff and They wanted to use the monster mask in in a project of theirs and you know this this board. It's wonderful It's so slim, but even then this um, you know the Elton John frames around the eyes were problematic for them it was still it was still too chunky for what they were doing and So I think Lamar showed these on a it's not out yet one time But we were both looking at at these round TFT displays and Anyway, I got the the the eyeball code Working on a itsy-bitsy M4 it took like surprisingly little work and These these displays because they don't have the big frame around them. Hopefully that will fit Inside their their monster application Better so that was just a weekend project that I did and I thought I'd show it Aren't they Thank you so much will be you Next up we're gonna go to Brent Brent what you got going on Hello, um this past week. I've been working on a different whipper snapper and we're getting close to finishing it towards a beta which is really exciting and one of the difficulties is how we're getting it to people and Like with a different I or do we know we distributed it like we had this configuration file and if you're using a Air lift on your board you would uncomment a line you would comment a line if you're using phono or ethernet and With circuit Python and all the work done in circuit Python. I thought that we can make it a little bit easier so Like I have a board over here and It's a metro M4 airlift and if I connect it You'll see a whipper volume mount Just like the circuit Python volume. Oh And that volume contains a secret start Jason and I'm not clicking it because it has my keys on it But what it looks like I have like a templated version And if it doesn't exist still make it already is you can store your IO username and your IO key and In addition to that you can store what type of network interface you're using So if you have like an ESP 32 s2 With native Wi-Fi built-in all you need is your SSID and password, right? But if you have a phono, you need Like your GSM ID in addition to a lot of other different Like properties that aren't available like through this native Wi-Fi interface So it'll let us like add different interfaces for different board types, and that's what I've been working on Very cool. You're making it too easy. We'll get that feedback later. So we'll deal with it All right. I love I love teeny USB making mass storage a thing Yeah All right. Thank you, Brent. Next up. We're gonna go to Shawn Okay, got the double digit key. What's going on Shawn? Yeah Oh, you're on mute, but There we go. I got it. I'm actually not repping digit key. This is my own project That I would get working last time and I got it working And I know I've shown this off before On a previous show until This is a great you got a great set up here Thanks. You've got my ultra wide and then my secondary I know just like I need one on this side with the vertical so I can do more code, right? And um, so what I've got here is the the feather stm Uh f405 and I was doing tensorflow light for micros on it by hand by converting stuff to a um, basically a spectrogram and then using uh a convolutional neural network to look for Spoken words from it. However is I've updated it to Edge impulse where I've just uploaded all of my samples and use their stuff which computes the mel frequency Sceptre coefficients, which are slower, but they did all sorts of optimization So now it runs happily in an stm 32f 405 and it works way better. So Here we go. So I've got still full control. Yep. Hadouken Oh Oh, you can't hadouken Oh, it's not listening. Here we go. Hadouken There we go Let's if I remember the actual combo, right? All right, sweet. All right. Good work. Thanks So that was um, try that's cool custom voice commands are really really really hard to do And it's not internet connected and it's an edge device You know, that's what one of the things that we always try to explain the folks why why we're interested in this Collectively as people who do electronics because you don't have to have a giant cloud computer with an always on microphone In your house You trained all the models and now it lives on that. So exactly everything's all the voice stuff's being run right here on this Little microcontroller. That's it. All right. Good work. Thank you. Thanks for having me Hadouken I don't know that constantly now All right, good work Sean. All right You are the street fighter. Uh, okay next up we're gonna go to bill. Hey bill Hey guys, how are you? All right, bill. What'd you get going on this week? I got I got weird stuff this week So what I've spent most of the week on has been working with dan halbert to get the uh, custom The scripture is working and they work So you can go into boot.pi In this case, I took a known good xbox adaptive controller gamepad I was able to manually enable it and it totally worked and the xbox doesn't freak out And I'm not having to use a custom build the circuit put circuit python. So that's awesome Um, he then made a mistake and asked me what would be next and I told him This eye gaze bar and it has multiple reports within one the scripture Which is gonna blow apart his stuff. So now now we're working on that. So that's what we're working on working on How's the customizable usb so far though? Is it have you been able to do the xac stuff or is that still yeah The xac stuff is great. In fact, it's very simple. You put in the this figuring out the descriptor shots But that's not your that's not your problem. Um Once you know the descriptor loading it in is easy We are gonna change this in that i'm gonna need to give him If there are multiple report IDs, I need to tell them what they are So he's gonna add that in that's gonna require a little change before 7o comes out But with that that's only for the next step for the current thing of I need a gamepad that is weird because xbox adaptive controller is weird It works perfectly and it's easy. It's super easy You put it in boot.py you have to remember to do a hard reset every once in a while and like that's it just works I saw how like accessibility technology. It's like you used to just be like, okay How can we like work with people and and like make you know diagrams and cards and now it's like, okay You have to know hid 3d printing Yeah, operating systems boot style keyboard configure like it's just so intense It's cool because like we actually can make this stuff It is it is very cool what we can do with python So I was never a python guy before I started working with you guys Uh, but what you can do with python and like 50 lines of python you can do ridiculous things right now Um, the thing that I wanted to show you Is something that I was asked for I only change what I'm looking at here. So This is what I want to show you. I don't think I've ever shown it here before but I should have because it's been over a year So this is actually I'm going to change go back to my camera for a second here so This is actually what I'm going to be making a bunch of I got a request from a large Company that won't be named that they're doing it an outreach event And they wanted something where they could teach people how to solder and they said do you have any kits or anything? That would be useful afterwards and they happen to have a lot of xbox adaptive controllers in their company um, and so this is something we designed a while ago that takes in Uh, this joystick, which is one of the so I took your design the more. Yeah I added two two jacks to it so that you don't have to do any wiring because Before that it looked like this with glue with little tiny wires So I made this design a while ago, but it really um, it was really kind of brutal to manufacture So I wanted to show this to uh, Noah and Pedro. I went into fusion And I made a negative of the board So you can literally just pop this thing on And you've got a dig for doing all your soldering. Isn't that great? That's all I did in fusion what was literally go in and and extrude down the um, the parts just I I can show you over here making jigs is usually the hardest part of manufacturing, but you are like Yeah, so so if you want to show show my screen for a second, I can show you guys this. Um So what I what I did was I took the the part because when we make part that I'm pretty sure um The Reese Brothers do the same thing They lay out their parts right because you can download all these parts You lay them out and then you build your case around it, right? So you build the top around it and you build the bottom around it And what I did was I just flipped it over. I turned off the knob flipped it over and projected parts into A jig right so if you look at the sketches um And turn the sketches on here right I projected in the parts And then I just added some space around them and pushed them down And it was super easy to make a jig that would hold that I did it took a couple of test prints But now I can give them the board the joystick the two switches and a and one jig For per table and they can crank these things out as just a you know way to practice soldering And I love this idea of making the jig with a 3d printer This is so cool. All right. Yeah, you should yeah work with another page Or maybe publish this up or or you know Yeah, we can make a guide on it. Absolutely. All right. We're gonna go out a lot of other people. So we gotta go, but uh Thank you so much. Good to see you All right for everyone else if you can keep it to like a minute and a half We have a full house tonight. We'll be more people showed up even okay, so let's go to eddie next. Hey eddie Hey, hello, what you got going on? Yeah. Oh cool So I shared this on the channel the other day, but uh, I'm building this is for the omega zero that I've been promoting Congrats on your efforts. We've been retweeting and been watching all the progress. Good work. Thank you. Thank you so much So this is running circuit python and this is to automate my garage But what's new here that I didn't share last time is Now I added the raspberry pi zero here And before this was sending all the information to the mqtt server on adafruit So that's where I owe and I can actually share can I share my screen so you guys can see the back All right, just keep it to you know a little bit under a minute so I can get everybody else and I'll uh As soon as I see it come up here all out. It's a big up So this is where the data was going before to the adafruit. Uh, can you see the Oh Okay, I guess it's not gonna allow me to do it Yes, anyway, so this is sending the data I have sensors that measure temperature humidity And a bunch of stuff on my garage So this is all sending it through this stack and then from the adafruit I owe back and I can trigger my to open and close my garage But also I can monitor the temperature and all that information from the dashboard Now the reason I changed now and added a raspberry pi zero in the between Is because I wanted to have real-time information. So I made a Mobile app so I can also see everything in real time Which I was able to do it through the back and on adafruit I owe but I wanted a little bit more control because I want to add different devices that tells me Home when the doors are stayed open like so I have left my garage open overnight a few times So I'm preventing that so this thing automatically detected this open and it will automatically close the garage It worked. I agree But thank you so much. I just wanted to share this Please feel free to drop links on where people can find out uh more as well. Thank you All right, thank you so much. We're gonna I'm gonna call these out in order so everyone can get on deck We're gonna go to tavis and then mic then stewart then mark. So we got a lot of folks at tavis. Hey tavis Hey Just project So I've been messing around with nixie tubes lately. So the first thing I did was these little dice that you roll Shake it. Oh, this is so dangerous Each one's a die. Yeah To give you a result So after I did this I made this little board so I could make Not have to hand wire everything and then Built this guy So my my pops did the artwork. Oh nice. Cool And uh, he's got two russian nixie tubes in the top And you guys's made led display the eyes And your soundboard is making the sounds Oh, this is great. This is great. I'm creeped out But also So if the top ones are some kind of Nixie tubes used for probably some kind of measuring device. I would ask probably measuring other nixie tubes Awesome I'm so it's reflecting Yeah, no, we can see it if uh, if and when you get around to taking some photos of it Can you uh, send me an email pt data for it so I could post these up on our blog? Yeah, yeah, and I'm good. I was gonna make a little youtube video to Yeah on my channel send send all that over and we'll do we'll do a blog post that looks beautiful. Awesome. Okay. Nicely done Next up we're gonna go to Mike. Hello. Hey, Mike. Hey, how you doing? Long time Let me go and share my screen here And then after mike will go to stewart then mark and we should get done just in time if everyone keeps it to like a minute ish all right After this sitting around for multiple months for the after the ate a box came New one came how to use it. So this is cycle 25 for all the ham radio guys and people wondering about that Sun runs an 11 year cycle So those from bad to really great then it's like sliding down and starts over again. So this shows the Info and depending on those numbers. I say get on the radio or get back to work Cool So I've done a couple of cool things because I didn't see it I have both the it sleeps four hours at a time But if you press one of the buttons, it will wake up on that. So I have both types of alarms working on here And I didn't see any example code that clearly showed how to do that Also, what I have is a battery alert. So if the battery voltage gets below 3.3 I wake up. I Say battery low beep 10 times and I wake up every two hours as we plug it into the usb c port For the events there are all the solar events And if you press it, it you know how this thing works takes a lot of update It will show right now. It's really rough But as soon as this thing decides to update there we go It it's just printing the raw first entry of the jason file that's published by noah cool I need to get a public And then it's your flash once more So you can go back to refresh or events So Examples that are using both time alarm time alarm and button alarm If not, maybe I can polish up do something and publish this on the learn site Yeah, we had a lot of ham radio people who'd love to do That well, I thought let's see sin Of course it's on github. There's the link Okay, cool. Thank you so much. Thank you All right, we're good to see you again. Yeah 73. All right. We're gonna go to Stuart and then mark back to back take away Stuart Oh, can you hear me? Yeah Yeah, so I was get ready for my uh vaccine. I guess sometime this month So I decided to make what everybody else was making cool. This is a remix from uh, No, uh, no knowing his brother. This is great. So what I did was um as the that's the um The qt pie 2040. Yeah, and the uh the o-leg and Use some laser cnc Laser cnc here and here for that and for the back I'm covering all the wires. What I did was I I got the back stl converted to spg and cut the Did a cut out from the creak cut From a light stock paper so I can cover the wires and things like that Once you turn it on it does a vaccine. I don't know if you can see it and This is a vaccine a vaccine And then it blinks the uh, the uh, the uh neopixels I love this project because when people imagine like vaccine passports in their heads They're like it's gonna be like this and you and you built it so good All right, so thank you so much super cyberpunk. All right mark place out All right mark and marks You can show uh my screen. Yeah So this was an old land trend that I grabbed at a friends when we were having campfire one day It was one of those free days when there was stuff on the street And this was probably 10 years ago. So I have since been working on it And I can stop sharing this and show the brand new one Which has now been restored The next step is to try to find plastic to replace the plastic on the inside So if anyone knows flexible plastic I can get in here Please let me know and then of course to put leds in it because why else would you build something? It almost looks like you got good reasons in new york. There is these like stained glass water towers They were art projects. Essentially. Um, it was that reminds me of that because it looks like a Um, but the flexible uh The flexible film that you use for uh lights might work. Yeah, it's pet g. Yeah Okay, that's very flexible I've learned a lot about plastics in the last two days. Yeah, just go go to the plastic shop They'll have they'll have sheets of it. It scratches easily, but it's super cheap. Yeah All right, well very cool mark. Thank you so much for coming by and sharing your very good find Hey, thanks a lot. I love we recycling. All right. Upcycling. That's it full house tonight. Thank you so much everybody This is our favorite half an hour every week show and tell we're here 7 30 p.m. Eastern time every Wednesday Next up asking engineers starts a matter of seconds. Yes. Bye everybody. See you on the other side
