 Lady Ada, what is this? Hey everybody and welcome to show and tell it's me lady Ada with me is mr. Lady Ada And I'm food scooch over here We're broadcasting live from the eight foot headquarters. You can see that all behind us. That isn't a green screen. That's a real factory Yeah, we do our testing shipping manufacturing kidding coding videoing and photoing and more wow but right now the factory is silent and why because We're here. We're gonna do show and tell it's hot on planet earth And hopefully the projects are fire. I mean then the best possible way So let's start off with J from Digi key J what you got cooking literally maybe this week. Hi Yes, no, I exactly don't have much to show but it's something to tell I have come back recently from Big River Falls The Digi key headquarters, and I can happily announce coming soon. I will be having my own youtube channel Well, not youtube channel. I'm gonna be on this huge channel Little thing where I get to show you guys I built my robots and built things like this and stuff like that But a lot of people have been asking me to you know hop on youtube and I'm finally doing it Outstanding. All right. Do you have any ideas of what it's gonna be on some of the the first round of shows that you do The first one I will admit was going to be with my aware of a robot fur the one that you guys saw me with That one and I have a few other ones We already have planned of already started recording the next one, but I don't want to spoil anything yet So I want to give you guys a little little surprises on this one right on well if folks want to subscribe to the channel It'll be the digi-key channel. Yeah, we'll be got it and we'll make sure we get the word out When we see it on Twitter, we'll hit retweet everyone Make sure you subscribe to the digi-key channel now if you want but I'm coming soon the J Starring Jay All right, Jay. Well, I'm looking forward to it. We've always said We want more electronic programming and I don't mean the firmware and the code I mean the the you know, we could have like me if we have enough of us will have like, you know maker TV So thanks for doing it Outstanding Okay, well, we'll see you next week or so Okay. Thank you. All right Jeff what you got going on this week? So I'm mostly going to talk keyboards today, although I'll start off with this little guy here LeMore recently put in the store this package of assorted buttons and I had busted my a button and look It's all But it's really intersect there's all these things I can fix now But anyway, so I think last time I was on I showed the Adafruit macro pad with QMK support And that was recently added and another thing they recently added is the ability to Convert any keyboard that uses the Arduino Pro micro microcontroller to work with the KB2040 Which has the RP 2040 microcontroller? So if you look down the end there, oh, yeah, that's the KB2040 and It's running QMK and this is called the gherkin. It's just 30 keys And it is the most compromised key layout that you'll ever see but it's so cute And it's one of the least expensive ones to put together and now you can easily switch it between running circuit python with something like KMK or running on QMK with their own firmwares and I'm working on a guide that's going to show how to do stuff like that How to set up your key maps There's a third one. It's not here because I only dreamed that I put it together. I made the fritzing I didn't actually put it on a breadboard You know how you remember things That's what's up learning about QMK and it is a fun little piece of software that has a lot of cool capabilities Yeah, it's kind of like the standard like issue keyboard firmware that people use. Hey JP Hi Yeah, it's got hundreds of keyboard configurations and dozens where you can use this conversion for the for the form factor Here's another one of those bareboards. So this shape is called pro micro Yeah, and the KB2040 matches it So you can just swap it out or solder a fresh one on or whatever. It's now our freebie When people check out on our website Yeah The QMK support for the RP 2040 is coming I think in August Yeah, so I'd send their branch that they called develop and it's only after it goes into their released version that Neat stuff like the online configurator will work. So for now, there's a few more steps But if you're into this definitely check out their develop branch Okay, all right. Thank you Jeff and if folks didn't know if you say JP or keyboard five times emerges keyboard All right, your turn John From one from one to another Jeff. All right So I want to show a couple things if you Jump to my shared screen there. I've got updates on my walk person Where the person is mp3. So this is a feather and for playing mp3 files over a little amp and I've got a snazzy little 2-inch TFT here And I'm using some of our neokies to advance rewind pause play songs. So if I hit Play here, you'll see I've got Daisy my Bartle beats there and I can fast forward to the next song There's play guys Pause that start that back up and these are running off of SD cards, so I Show you why I've got these snazzy headphones because a lot of this is inspired by old-school Walkman styling Sony walkman styling. So I've been building this case this stuff out of the way get out of the way stuff To house all that stuff that you saw down there below. So I've got the screen here. There's a spot for the feather there I've got my little four Neokies up here for the controls and I've got a little headphone jack out there And then I'm adding rotary controller support to be able to do other settings including volume on that using the Audio mixer in circuit Python and all this running in circuit Python. I've also got the little SD card extender there because the SD card is part of the back of the display and Little port there for charging your battery with the feather itself or doing data on the feather So this is my little mp3 walkman walk person style project. I'm working on Looks like on the desk before it becomes That's that's all that somehow crams into this that's the challenge of it And so I've been having fun designing this and getting it all to fit together And I'm also gonna be collaborating with the Ruiz brothers so they can do some of their Magical snap fit types of things that they do so well with 3d design so that it's a Nice easy design for people to print and build and put together so that's in process and I might not finish the guide for that for a little while because we're Figuring out a couple things about power supply since the great chip shortage has made it harder for us to Possibly do five volts to it the way we wanted to but I've now got Lamar on the job helping me figure out why I'm not Possibly doing things right and running this off of three volts for that. I'm sure it's fine Especially with audio noise is such a pain to deal with but we'll figure it out. We'll figure it out One side note if folks Do a web search for sony's warren makers? I think this is when jp and I were at make together I did an article about at the time so sony's chilled out since then But at the time sony was like going after makers for doing a lot of projects If you hacked your ibo if you did a bunch of stuff for the playstation But when the ipod came out People were Making cases for the ipod out of old sony walkman and it was the cool yellow waterproof one And they were selling them online as artisanal cases and sony was so upset because Obviously, they would have liked to make the ipod, but instead they didn't and The the design of the of the walkman was so beautiful people wanted that as an ipod case So this kind of reminds me of that a little bit Yeah, for sure. You can still get those on ebay and you can still mod them and turn them into cases. So, uh, yeah Good stuff. All right. Thank you for wishing they they hadn't because of thanks to stranger things in particular all Possibly working walk walkman are like going through the roof on ebay. Oh, fine. It's a good time to make your 3d printed version Then I have a small collection that I didn't realize would be Valuable now I guess Now You should be all right next up. No, I'm Pedro. What you got printing this week Hey guys Hey, so this week we're uh doing some like 3d self fees and turning ourselves into action figures So pts. He saw this really cool thing. It has rose releasing it where it's a 3d selfie. Where am I? Oh, yeah, let me um Thank you Yeah, so here's a cool scan of noet and one of the cool things that we found that really looks like a flex Yeah, ninja flex works really good on this Pop up the head and these is actually part of their line where it's actually called build Build a figure. Yeah, so this is like specifically Designed for these so the ball sockets are all nice. I don't break off or anything And you can't customize these with your own sizes. They're not all standard sizes So they all like different this is some type of Freudian experience I'm sure between brothers that I'm not going to comment on so weird, right? I know it's so crazy the kids have super fun playing with these playing with you know mom and dad I do like so So for the folks who are like super fans out there, uh, natalie portman is like Like Thor look at Thor like entity and in this whatever movie I haven't had time to keep up with the latest Thor movie But I I don't know if they have an action figure of her yet. Did they do that yet? Didn't not So here's the story. I'm walking in, you know to buy these dolls and there's the active figure. So there's the the The dad and the daughter and the daughter's like, you know Dad girls can't be kings and you know, cool super dad is like, yes, honey Girls can be kings and it's like, oh, yes, I have to do this project because you know It just jerks you like yes, dude Do anybody can be whatever you want and this is a really good example You know, whatever including yourself as Thor or whatever, you know, yeah Really rare that you see like brown star Cooper So this is really cool to be able to print yourself as and I think that's what has gross trying to you know Get across that you can you know turn yourself into that superhero You can be you know, everything. Yeah, you can be that and especially with things like this where you know I wanted to match like how Groot has like the The the moss all over him. So yeah paint, you know Might be or you can paint it all green stuff like that and the cool thing is this is wood PLA so you can like incorporate that really does materials Yeah, the funny thing after that that daughter and dad Moment my son's like dad. Who's George Lucas? They're like be quiet Gavin because this is what nobody knows So it's funny that you know, the kids that's cool mom and dad as the superhero So yeah, super cool. All the files are available on the learn guides. You can get a different ball socket So that's all you have to do really and then a whole detailed guide on how to actually scan this Super easy. I took so long trying to do all these different techniques and it turns out it was just like photos Take 50 photos all around Make sure you get the bottom of your chin the top of your head So all that geometry is created and that was really fascinating that they don't they don't use like a motion scan They just take the photos and they stitch them Yeah, so on 3d hangouts I show like comparisons of what like the lidar scan looks like what the photo scan looks like And then the the other with the dot matrix one that the iphone uses for the face id stuff Um, all those come out like garbage except the uh the photo one So yeah, check out the guy check out the 3d hangouts on it's a whole hour on discussing all this like the materials Like I may have super happy that you're able to print out 100 microns So not as detailed as like the form labs, but pretty pretty close You can obviously tell who that is I mean you work you paint it. It's all the detail is there. I mean they happen to paint anyway Yeah, but yeah a bunch of different ways you can like paint everything all different. So All right, very cool All right, thanks so much All right next up Liz. Would you get going on this week? Hey, how's it going? Um, so starting to work on a new project. Uh, that's going to be a two-way servo display where we're going to have two qpi esp 32 s twos um Kind of talking back and forth to each other. So I had a proof of concept of today where if I do a cap touch on the qt pi Um in a second the neopixel is going to turn red on both of them. So, um My display um on ios should also update in a second. Let's see Maybe I don't think it's connecting Live demo Live demo, right? Um, well, it's I can also do the um another pin on here on the feather And go pin nine and they should update to blue. Yeah Um, so and then that's weird Hey Yeah, you can see the blue dots and the top tell you that data's coming in you have some Debugging to do yeah, okay Um Yes, uh, yeah, so um, basically I was just trying out the logic. Um, having them communicate on a feed and Setting data back and forth to each other. Um, and so next we'll be adding in the servo positioning. Uh, and go from there All right, thanks so much Next uh paint your dragon What's going on? Hi. I have an astone of neopixel Yeah, astone is that yeah, it's fine. That's fine. Okay. Good. Um, I actually I showed this this thing a few weeks ago um, we have this this feather wing and software combo called neopixel eight that um, You know neopixel aren't quick to update like if you have a long string of them Of it kind of ties up your microcontroller. So we made this thing that splits up the job eight ways And it can update then eight times as fast Um, so originally that was m4 chips only but since then we've added rp20 40 and now esp 32 s3 um So all this, you know, I mentioned a few a few weeks back But um, what I didn't mention that at the same time we kind of snuck in There is a new object class in that library called neopixel eight hdr And that does what it says on the tin of you can't see here through through crappy web video, but um, it actually does very nuanced, um Shading of the neopixels normally if you have like a brightness ramp From max down to off It kind of cuts off at the low end You can't get these, you know really Uh subtle shades and so what neopixel eight hdr does Because you have two cores on these chips now It just takes over one core and just continually refreshes the led super fast Doing dithering with the dithering Um, you dither the dither. Yeah, it's dithering all the way down. And so, um, like I say it's it's not going to show great here But trust me in person. It's like, oh, that is like super buttery smooth Oh, you know, you know, you should have for the for the example. You should have it switch every 10 seconds show show Yeah, people can really see because you'll be like, wow, that looks amazing when you see the difference So I don't have a great demo for it. Unfortunately, like the code's there Yeah, that's cool gotta do some kind of like killer app that shows I can actually kind of tell it doesn't look in the little thumbnail It looks really good because it's smaller You can also put a diffuser thing on top of it Probably see if it looks really good in the in the preview because when you get close up, you know Obviously, it's it's webcam land. Yeah, and there are um in the neopixel 8 library, there's several examples and there's both Regular neopixel 8 and an hdr version as separate files. It doesn't switch between but That switching between might be a good idea because you can really It's it's nice. It just looks really nice. It's it's if you're into big-ass neopixel project. It's Last time We like big leds and we cannot lie. All right. All right. Well, thank you so much. All right. Thank you, philly All right. Next up. We're gonna go master of leds and dragons tim from the guy How are you doing? Hello So this week I am excited to show off this hack tablet. This is a seven inch Crestron tablet. It would have originally been sold for like conference room signage I got to say also hug report to kmatch kmatch has put this together using a esp 32 s3 and then a custom board that plugs into the touchscreen as well Is in the waiting room here. So I think kmatch is going to be on in a bit too. Yeah, all right Good hug report. So this is all all hooked up running circuit python on that esp 32 s3 We have multi-touch working. So as of a little while ago the circuit python focal touch library Has support for multi touch. So I got this demo together with six fingers Um, it can actually support up to 10 and I've tested that out and 10 works But this particular demo doesn't have 10 in it Um, it is a capacitive screen. So you can kind of drag around, you know Like resistive screens you have to touch a little bit harder and it's kind of you know You can't quite do drags and you can't do quick taps and stuff. Um, yeah, but still Yeah Series Yep, they're they're basic, but they do work. It's like my first pda. It's cool. Yeah, yeah, um, so Really excited that this thing is here and to show off the example of it And then other exciting news is that we're actually going to have a couple of these that we can give out to the community. So Um, for right now what folks can do is get in touch with me. Just drop me a line on discord And just let me know that you're interested and then they'll we'll have an announcement out soon For like what to do for folks that are interested in getting one of these devices to play with and Hopefully help us get the bugs worked out to get everything ready to go to merge into um, circuit python This is amazing. This is like one of the first like fully pythonic tablets Yeah, that's cool. That is really neat. I'm really excited. Okay. Well good work And are you going to show this off in any form on your show this week? Yes, yeah, I'll mention to last week on deep dive. We looked at the same device We worked on a build for it. Um, and I'll probably be playing around with this some more this week on deep dive. Yeah, all right Okay, thank you. All right. You want to go to kmax? You want that's right? We're gonna we're gonna do a doubleheader here Hey, thanks for doing all this stuff came out. Oh, sure thing. Yeah, and basically it was fallen from the first Pipe portal. Yeah box. So but why not make it bigger? Yeah So part of it was also spurred from maker melissa's request for some gooey Basically graphical user interface elements. So you can do that here with uh, you know, this here's a like example of a sliding switch But uh, also has some annotation widgets. So So this is a library that's available for touch screens and yeah displays Uh, but of course, you know, that's that's kind of small So once you want to try to do multi-touch or put a lot of widgets on on the screen it gets limiting So so as as tim mentioned, I came into some of these displays that are conference frame Uh things and basically a lot of these are getting depopulated. I think so you can actually no one goes to offices anymore Well, it's true. Yeah, our conference room is even worse I like the idea of taking, you know, yeah these these screens with the nice enclosures with cap buttons on the side and then And then just repurposing them. That's a great idea because the the ttl display interface is standard And almost every capacitive touch screen is focal touch or one of the similar. They're all very similar Yeah, that's right. Yeah, the pinouts are different for each display, but uh, now that there's you know, you can buy these, uh, ESP32 s3 chips can really handle all these pixels. They've got a ton of ram Have uh, basically run at 240 megahertz plus. They also now have an lcd peripheral Yeah, basically allows you to drive that without having to have a Controller chip in between so that may save you some cost on your discharge too Especially also that you know the ra8875 which we've used historically is Is totally unobtainium right now the price tripled and you can't get them and they're probably going to be discontinued So I like that this chip came in right at the right time Exactly, plus you you know, that you know the tablet is probably going to be the most expensive part of the You know, yeah, so anything to reduce the cost so so basically I like like Tim showed you've got good touch Yeah, and just to highlight a couple of more widgets So oh right on you got some like if you want to set the date for you know, the future you want to go to or whatever You can yeah, of course. Got some touch like that or this also has uh, at least the board I built has some stem of qt ports. So you can put it in like a yeah, you know knob So fancy knob action and it shows off some of the the dial Different forms and look at that rotated font action man Yeah, and actually that's using some bitmap tools that have been coming into use of rotating and scaling bitmaps. So There's a lot of new graphic Are just like banging these out outstanding work I like that these poor little tablets thought they were in some type of hell like, you know For their entire existence and now they're getting a new life and uh They're fulfilling their potential Yep, that's right. So basically gives you a lot more real estate Yeah, and they try new things and this is all running circuit python and as tim mentioned We're going to elicit some help of folks that will help get some of this new capability merged into the main core Yeah, when we were coming up with the the pi portal Um, one of the things that we thought is oh, you know one day You'll be able to like make a whole os with circuit python And maybe you could start doing things like the l cars interface from star track and all that and we're like Oh like one day one day one day and that day is here So I gotta get some of my uh five Yeah, I've got some samples of five inch and seven inch capacitive displays and and and I want One of the things when I saw the esp32 s3 had the ttl display. I was just like oh, that's really cool Even that's only 16 bit. Um, I mean a lot of displays now that you know the really cool round displays Rgbtl. So maybe we'll make a round pi portal. Oh, cool. Yeah. Awesome. Well, great work. Yep. Yep. Thanks a lot Okay, we'll help you out with um, you know when it's ready to go. Yeah Oh, yeah. Yeah, that's exciting. Yeah. All right. Well, thank you so much, John All right Speaking of tablets joey, you've made a tablet. This is like circuit python tablet. Uh, I know there's DIY. Yeah, DIY tablets. How you doing joey? Oh, you're still on mute. Sorry. Yeah, i'm doing well. Thanks y'all. There you go. What's going on? So this isn't an open book thing actually. This is a lcd type thing. Let me uh, yeah Uh, here Are you uh All right, here it is. It's beaming in Great. Okay So yeah, so um, I have here the um lcd feather wing and I did my first driver in circuit python Just because it's so easy to like like code up an lcd driver in a circuit python It's just like a joy um, but I knew I wanted to get an arduino library together because You know people also use arduino and it's um, let's you do some things like Kind of low power sketch So here i'm using uh y'all's itta fruit sleepy dog library to go to sleep for 10 seconds in between loops and I'm gonna start my handy dandy Oh, yeah, you'll be able to our profiler to see it turn off. There it is. Yeah, so when it's uh, it's like sleepy dog state It's only consuming about a hundred microamps and then every 10 seconds you get a little bump But this would be a really great way to do like an always-on kind of display for a project That's all the regulator too. I would I didn't pick a you know The regulator I picked has about 80 microamps of quiescent current So if you want to yank that off and we'll place it with a different one You'll get you'll get down to 10 microamps or less Totally and I think there's also like you can mess with some Something like kind of get a little lower But I think it's really cool to just with not too much, you know extra configuration or work You can get something that hundreds of microamps is nothing to stop at, you know, yeah All right. This is so cool. I love all this stuff coming out Yes, like I just finished on the whole day the uh circuit or the um lcd feather wing Arduino library, so that's out there now and yeah, so let's see what folks are gonna do with it Okay, well, we're gonna stock that soon. We've got an order with you Um, it looks beautiful great work with it and yeah, well, you know, I I think it's a neat It's a neat ecosystem. I think like you saw that we did an ion impi or a great search And we like showed off this chip and then you're like, that's a cool chip and you're like, I'm gonna make a product Then you made a custom lcd, right? So I'm gonna break a little a little bit of a rule So we have I think you've you've heard this before we have a weekly meeting in a different called state of the fruit And um in state of the fruit It's all of our metrics and numbers and all the All the things the team share and then at the end we have hug reports Just like we do and you know discord and all that stuff So joey you got a hug report behind the scenes for being the the best new vendor Um, because you had uh, yeah, you had successfully filled out everything perfectly and everything was exactly and when you shift Apparently like the tracking number was everything was great. Yeah, and like the number of items was correct and like that's not Yeah common. Usually it's a bit of a jumble Yeah, the level of vendors but it can be confusing and these are like you're up against multi billion dollar international companies You gotta write the first time that have fleets of people that just do all this stuff But uh, you got a hug report. So I told the team. I'm like, oh, I'm gonna tell you I gotta say I guess an anecdote if we have a moment just gonna say like I just went back Because I was curious as I was like packing up the ship to y'all I went back and I found my first ate a fruit order in 2014 which was electronics toolkit It just right on circle to become now shipping something to y'all. So yeah, that's so cool. Yeah Outstanding congratulations. I'm excited to stop more and more products from you And then we also still have on our very long to-do list. Uh, jay had one, uh hackaday prize uh I think it was hackaday prize, but we we're doing to do a short run of a yin thing together one day But they're keeps being coveted. Yeah one day. Yeah Okay We're good to see you. The chips and the displays are getting better. Yeah, who would have thought Um, and there's a cheap shortage. Um, and uh, once again, congratulations on being vendor of the year Thanks, y'all. All right. Thank you. Take care. All right. Let's okay. That is our Someone else come in. Oh, john just came in it was hiding there. Hey, john. How's it going? Do you want to go fast? Yeah? Go for it spin it. Yeah, really fast. Uh, so I've been working on this argument. Oh project I had an idea a long time ago finally implemented it. Um, I just got three, um Distance sensors on this little box here and uh each distance sensor. Oh Parlakes to an rgb channel, right? So the further away you set something Adjust oh, that's neat So, uh, he's a color sermon Yeah, exactly All right, what a fun project. That's a cool idea Yeah outstanding and if uh, you put it anywhere online or anything let us know you can also email me pt data for it And we'll get up on the blog so people can make and remake that as well Awesome. Thank you. All right, john. Well, thank you so much. Keep coming back. Thank you john. Thank everybody Wow, what an epic chantel. Yeah, great to see you all We've got our next show asking if you're coming up in like one and a half minutes So we're gonna jet get ready. Thanks for making this the best happen hour of our week every single week everyone Ask an engineer starts in a couple minutes and thanks for showing everyone makes something everyone shares something We come together and we can make things a lot of fun glowy right LCD low power Music making that's right. Okay. We'll see everybody in a few moments on asking an engineer Hi everybody
