 That's the beat hello everybody welcome to Aderford show and tell to show where we are hosting Yeah, this is where folks we invite folks from the community to come on and share projects whether it's 3d printing biohacking Whatever we're making 3d pretty retro software long list of things all the things we're going to start off with folks from the community from Aderford and then the community Take about like a minute or two and if you want to join it get up on discord.gg slash Aderford Well, you'll see the link to get up on the show until first gonna start off with a brand rebel Brent, where are you? There you are Hey guys. Hey, so the past week Yeah, we have some exciting stuff to show for Aderford IO so this is a collaborative effort between me and Melissa and She worked on the website of things and I worked on the hardware side of things and now if you have an ESP32 board so like the Feather ESP32 I'm also starting to play around with some of the Sona switches that are really really Inexpensive like the mini ones are pretty cheap too you can use it with whippersnapper and What's really neat is that? You don't need to install anything so you plug in your board and If you've seen ESP web tool which Melissa also worked on this uses the Chrome browser as a serial connection So you can select the this doesn't show it on Like Streamyard, but it shows it on mine and you select the board and it attempts to reset the board and Maybe it doesn't Awesome, I love demos All right, and then it connects to it. So then you enter your SSID Your password which is I just changed it like two minutes ago And then it has the script on it already your Adafruit IO username And I just generated a new password and then you just click install whippersnapper And what it does is it erases the flash and then it installs your credentials into the non-volatile memory section of DSP32 and this is a really interesting way of provisioning devices because previously Like if you were using a feather and it was like in the field, right? Like you and you make a sensor node and you install it and there was a person who was like installing it Literally near a volcano and Adafruit forms and he was like I got to wait like three weeks to get back to the volcano This is a way of doing things This is an OTA, but this is a way of doing things for you Don't need somebody with an IDE and experience with Arduino or experience With anything but like the internet so you should be able to like if you're an educator and you're bringing boards To and from a classroom you can only update your credentials or you want to flash it to use a different users Board and the different credentials you can do it from here and like unlike other IoT platforms There's no agent that needs to be run on the computer itself. It's all run in the Chrome browser, which is really nice Um, it takes like 86 seconds about and should be done a little bit and then when it's finished It will disconnect from this and it will pop up on whippersnapper and say I'm an ESP 32 So I'll give it like a few seconds The beat you guys did earlier No, that was whack man That was me trying to do a beat. Yeah. All right, there we go And then it generates then vs and then it's done. So if you reset the device like I'll just physically press a button um, the device by desk is glowing and then It checks in to whippersnapper Says we have a new his off 32 and you can name it and it shows the firmware version. It's running now as well And you're all set and then you can add components to the device So this is a new thing and if you want an invite for it Go to the adafruit discord, which is adafruit.it Slash discord and go to the help with adafruit.io channel And just type I want an invite to whippersnapper and I'll take care of it Don't message me directly just type in that channel and I'll take care of it all right well done so cool, so Do you think like a wider release beta will be out um end of this month? I hope oh We're pretty close. Yeah, awesome. Yeah, well done. This is a great. I'll say it on air like that's that's that's what i'm looking at Okay, cool. All right. Can't wait to try this out. It's so cool. Yeah, man Awesome. Well, thanks for that. Thanks. Well, yeah, we'll see some more stuff later on. All right Cool. Next up. We're gonna jump in to kevin kevin. Hey kev. Hey, how are you guys doing? Good to see you Yay, happy wednesday. Happy show and sell day. Yeah, yeah for sure uh Couple things uh first thing that I was working on is looking on my demo for sensors expo And this thing is really cool. This is called a phase doc. You can get these at digike um, there's different slides and Holders for different boards and make it for all sorts and this one i'm doing a demo on the You know the aida fruit stemma qt and all the different peripherals and sensors I can get a little closer to it. But you know, you can either zip ties Yeah, you can zip tie it to the board and it's got a clear plastic cover. You can throw this in a backpack um, these are great for schools or You know anybody that's doing i've seen so many cool products on here I'm showing tell and if you want a way to keep it somewhat portable and safe and together These things are really cool. So check them out on digikey and the other thing I wanted to bring up is our halloween contest on hackaday And yes, and there it is. So halloween hack fast And you know, there's again so many projects that I see i'm showing tell so go put these halloween projects on On hackaday and entering your chance to win The prize if you use an aida fruit board is doubled So that's pretty cool. Yeah, that's awesome. Yeah, there's some conscious entries as well Um, yes, there's three projects right now. So you have plenty of time. I think the deadline was october 11th If i'm not mistaken So there's plenty of time to get in on on it now But yeah, if you haven't already signed up to hackaday. Oh, it's free to do so and you can start Post it up your photos of your projects Yeah, definitely. Yeah, kind of get started right now. So you don't have that excuse of oh, no, it's too late Or it's too late. Yeah. Yeah, the one that halloween is year round Yeah, sure. It's yeah, the course one. I think is this Yeah, I think the skeleton one if you guys want to get some inspiration is really cool It's adding a motor to one of those 12 foot skeletons that like, you know, sort of blew up everybody's getting Yes, yes, they are amazing. I feel like I play the audio, but it's like the pirate song. Yeah for disney We don't want we don't want to copy strike. But yeah, definitely take it out. Uh, it is at uh Hack at hackaday.io. Yeah, you just make your project and then on the side bar There's the thing you click app to submit to the to the contest. How cool. Cool Very cool. Well, thanks guys. Happy showing us all day. Thank you. Yeah, we'll see you next time. Bye All right, next up we're gonna jump in with john park john. Hey john. Hey guys, how you doing? All right, here we go. So, uh, I've got a couple projects that I've been doing using this little snap apart PCB keyboard. So this is for mechanical key switches. Um, I ought to have some around here. Here's a couple I'm gonna wander off for a second. Uh, so these are hot swap sockets that you can plug the key switches into and they are, um, connected as a diode matrix with columns and rows And there's a neopixel snaking its way through here, but you can snap these apart where the little sort of Nibble perforations are either to just reduce the size down or to reconnect it in a different configuration. So Last week on my show, I was, uh, working on this and I just published the guide. This is my I'm calling it the num pad 2000 No, 4000. It's twice Uh And the the neat thing with this one is that I've taken things off the grid So you can see these keys here are all one unit size one u But I wanted to use the big honkin plus enter and zero So that means that there's some snapping apart and reconfiguring and resoldering that goes on I left the back open so we could just see that you probably want to make a version with that covered if you're really using this in In a typical spilling your soda all over the place kind of environment But this you can see and hear some of the wiring that goes on to to kind of keep the Neopixel strand flowing through that's that white line There's some ground that's being connected some voltage and then the yellow here are some Columns and there's some blue for some rows. So that one the guide will show you how to set all that up and You can see here. I've got a nice big Feather rp 2040 here that these are connected to kind of hidden up under there and this is a One of the reasons I chose this is I do have quite a few columns and rows to deal with so I needed A decent amount of gpio. However, what I'm working on next is a four by four keypad Uh, so this one stays on the grid This one uses our super cool, uh, aluminum case that we're selling now. It's an aluminum case. It has a I think it's an aluminum plate might be a steel plate for the key switches to snap into Your neopixel board fits in there and then since uh, I had already Done this sort of external big honking board one I really wanted to challenge myself to fit everything inside this case because it's a pretty case so I've got a Cutie pie in here. This is a cutie pie m0 But you could also do this I think with the cutie pie rp 2040 it should fit It's really really very little clearance in there But I found a way and so I'm going to be showing that off on my show tomorrow And I'll be writing up a guide on how to make your own This one is running arduino and just a keypad demo Right now and I and I set it up to do some Neopixel stuff when you press the keys. It's nice and clicky Jade switches in there. Um, but I may I was issued a challenge by uh, la more just a half hour ago She said hey, maybe you can get qmk working on this, which is a really popular Keyboard management software for microcontrollers or firmware for microcontrollers or people who are making custom keyboards So maybe that's the next step with this Uh, and I think that's it. That's what I've got And uh, you can come on by tomorrow to see How this works and what's going on in here and how that possibly could fit in there Breaking cool and congrats on 200 200 episodes. Thank you. Yeah 200 episode tomorrow. Can you believe at the time? We're gonna be having cake for you Everybody is Are you sharing? See you tomorrow. Thanks. Yes. Oh you next up. Let's see what scott's working on. Hey scott. Hello Um There we go Waited. Yeah, so i'm diving into usb We have this bug for circuit python 7 that says hey the teensy just doesn't work at all Um, well, it kind of works the circuit python code works, but the usb side doesn't work So I have been digging deep into the weeds of usb And what you have here is this is a capture of all of the traffic on usb And all these red lines are the ones where the protocol analyzer thinks it's uh incorrect So basically what i'm doing is i'm taking a look at uh, these red lines and trying to figure out why Circuit python is not responding in the way that uh would make sense So if things work well, you get this like a higher level protocol description of like this is getting the device descriptor And then right after that you can see that. Oh, it does a second thing and the second things fail. So um I'm on my way Uh But uh, it's a it's very deep So, uh, I think I'll plan on covering it on friday for me my deep dive if people want to see me Uh hammering on usb. I think I figured it out so that I can have like all my cameras on different usb buses Um, because the danger in showing us because you can like say, yeah Break your usb bus like it can be really bad for audio and video and all that sort of order other sort of stuff Tight rope walking. Oh my gosh. Yeah, so we might give that a try. Uh, folks have been really, uh, patient with me If I've had technical troubles during my deep dive So thanks to everybody for that and I just wanted to say Um, I also wanted to say hey, it's been five years that I've worked for adafruit Yes, yes I think to the day when you went on show and telling you got the email from pt Yeah, so it's it's been five five years since I got the email from phil Which is the day after I was on show and tell but uh, I've been doing show and tell a long time And uh, I'm happy to be here and happy to be working on circuit python for adafruit No, I'm glad you came you came on to say that because it's a good reminder that coming on the show and tell It's pretty much like a honeypot. This is where we find a lot of the people. I mean, that's how we get on too Totally. Yeah. Yeah, it's a great place to show your work Um, even when it's usb. That's not working It eventually gets there Yeah, we'll figure it out Hopefully it won't take me weeks. That's the real thing All right. Well, thanks so much for showing us that and we'll have cake for you as well I think we're gonna have like a bunch of little cakes for everyone. Yes. All right. Don't forget to exercise too Oh, yeah. Oh, this dog does not let's forget that Good. All right. Scott. We'll see you next time. Great one. Thanks All right. Next up. We're gonna check in with the community. We have two folks here. Uh, eddysio. We got you here Eddysio Hello. Hey, hello. Hello. Sorry. Hey, uh, so me and my father made another project together Okay, uh, it is another, you know, uh Sweet and it is like five votes. Uh, we didn't not Uh, we we did make some some changes in the project like we put I I can show in the camera, but we added some things to to connect the to connect the The oh the the cable for the energy so you can connect, uh Uh, it in a place that is close to the To this cable here. So you just put the pins here in this direction. You see uh Uh, it also I saw the red may probably most of the parts but my father saw the red some of other components and uh In a few weeks, probably we will be doing another Arduino and uh, we will buy the the five PCBs But uh, we will make the changes and make it Oh, I know Get some uh So I hope you like it. It's another project nothing very special, but we like it a lot to do That's great. It's always great to collab with uh with your folks. Yeah, yeah Definitely post a link in the discord if you can awesome. They come up for sharing. All right And come back and show us more projects. Yeah. Yeah to get the reds out. Yeah, awesome. All right. Thank you. Thanks All right next up, uh, we'll jump in with gary. Hey gary Hey guys, um, just early morning on uh, Thursday morning in australia. So Oh So just on uh, I showed off a tron project before and I'm just showing off another version, you know the light cycle baton Yes So I made both the black version and I know this is out as a toy But I thought I'd add some electronics magic and I did a white version as well Nice So I printed off the stainless section using a resin printer So this is some nice detail and you know, what's a good prop without some electronics magic I just added a small little cap touch at the back I'm just touching it off Just sets of this And depending on which faction you're part of, you know, you just go red if you want And uh, and I just threw in some green as well just to you know, because you can And off and there we go. Great. So I just Showed off another toys out there, but I thought, you know, you can always just do something So extra cool with using some meta fruit of uh, uh, microcontrollers and some Neopixels, so yeah, that's a for me. I always encourage people to remake it because the toys like that are manufactured Are always as good as something you could make yourself Awesome, and oh, I love the light cycles in the back to the background or touch Yeah, I just thought it's my workshop's a bit of a maze of the 17 day Thanks guys. Thanks Gary All right, next up we'll check in with Carl and Chelsea. Hey guys. Hello. Hey Hello. Hi, I'm Carl. That's Chelsea. Hey, how you guys doing? Good. We're in California. We have smoke I know yeah, but at least no rolling power outages yet um We're at a small semi conductor company in silicon valley We do analog chips and Chelsea is my intern for the summer And we've been using your boards to demo our evaluation kits So we recently came out with a line of rgb drivers that has some unique attributes that give us some nice advantages for people and This is like one of our demo boards right here. This one uses the feather rp 2040 And it was programmed in I don't know what lights on it was programmed using micro python So we put that a diffuser where you can see it from the front or the back and We have a software script in there That runs for about seven minutes in a loop to demo all sorts of patterns and colors and crazy stuff More than any product would usually ever want But what we did is we made a library of functions to do different patterns There's a couple I mentioned we had attributes that are unique So these are current sync regulators with switches to the high side That basically we use charlie plexing and I think adder fruit is probably a few companies that knows what that is So it's charlie plex. So I have very few wires going on pc board traces going to the leds themselves We basically use 12 wires to do 12 rgbs on this product And so it's a three four wire buses Um, it's actually kind of unique because we don't charlie plex fully and there's some technical reasons This is how the pc board is designed So you can see that we have the a little three by three chip and then there's four wire buses each going to four rgbs And so the idea here is it minimizes your routing So we get a lot of customers say oh we used to use a lot of wires a lot of layers to do it and It kind of started by us dissecting the amazon doc It has a chip from somebody that you guys have used it on your web page And so and it's a five by five and we did a three by three that does everything and more That was one thing How cool, so it's Yeah, third the wires third the chip size size translates to the cost in our industry. Oh, yeah Definitely less layers. Oh, yeah More efficiency in the getting the PCBs out And then one other cool thing we did so this is a small one. It's the two by two millimeter does four rgbs and so that's uh For customers that want indicator lights or something Helicon designed this into a few things So What processor we using? Oh, this one uses the cutie pie sam v 21 And so we programmed it we programmed it in the arduino id Excellent I like the use of the stemma cable. It's a really good way to plug into it. Yes Our first yeah, our first attempt was before we hired her. We had like just some regular You know header pens and we Yeah, so we're changing everything all our boards right now it's soldered in but we're redesigning all our boards Yeah Once you go stemma. Yeah, it's yeah, it's really hard to go back once you just quickly Especially for you know doing the about boards where you want to constantly, you know switch them out and change them out Yeah, it's Another thing Chelsea worked on was we changed our color space in our software to be um s rgb So it matches your screen colors. That's pretty easy. It's just a little math Excellent, then Definitely get another board where we bridge two chips together into a light bar right now. It's not lighting everything. It's kind of all white here This one does See if I can get it to show colors Over saturating with this camera, but we're doing random colors to random LEDs right now And so it's just one of our patterns we have now we're doing some log breathing Yeah so But the patterns go contiguous across multiple chips and we wrote our software to allow that pretty easily Um, because it's parameterizing you can put a map of how many chips are on the bus and everything One other are you guys still there because we see a black screen. Oh Can you hear us We're having a connection problem. Maybe yeah, yeah, you're right next to us. Yeah, if you can hear us, uh, keep keep going You're a little choppy when you came back here. We're here. Can you hear us? Yeah, we're having some sort of a connection problem. Oh, no. Yes live streaming. That's don't worry though. We saw everything you demoed Yeah, it looks really good. All right. I guess we'll uh We'll end it here. Yeah, it looks we got about like eight minutes. But yeah, I think that is everyone All right. Well, thanks Carl and Chelsea for coming in if you folks can still see us Yeah, don't worry. We can't hear you guys It's very choppy audio coming through and there's no video. Um, so there's some sort of a network problem going on all right all right, well We'll uh, we'll catch you next time I suppose but thanks for hanging in there folks. Maybe we have to call you guys back in We'll try that It's all good All right, folks. Well, that's the show and tell it's a live stream on the internet and sometimes things like that happen But thank you everybody for coming in, um Don't forget. Yeah, don't go anywhere because then a couple minutes We'll have Lamar and Phil here not here but over there on this youtube channel thing That's it. We're gonna go now Bye folks. See you next week. Thanks everybody
