 and that means it's time for Adafruit show and tell hello everybody my name is Liz and I'm guest hosting this evening for show and tell if you would like to join to show up your project you can go to the discord at adafruit.it slash discord in the live broadcast chat there is a link you can join to come into StreamYard and we will chat with you about your project first we're going to kick things off with some folks at Adafruit and then we will hear from folks in the community so first let's hear from Jeff hello boy that clock must be pretty accurate that was just exactly to the right minute thank you yes yeah so I've been working for a couple of weeks on adding support for a new kind of display to circuit python and these are called by a number of names but I call them dot clock displays and basically the microcontroller manages everything about what's going out to the display so it sends like the RGB pixel data and horizontal and vertical sync pulses continuously and this is pretty cool because we hope it's going to enable us to work with a larger range of displays so anyway if you want to bring up my screen share I'll kind of show you what's going on yeah and really I just got this going earlier today so I don't have a cool demo I think in ask an engineer Lamar is going to have a little more of a demo because she was taking time putting that together but I started with this board here which is from Tindi it's the brand is maker fabs or something and it's got a 800 by 480 display on it and an ESP 32 s3 microcontroller and it's just switching back and forth here between showing the information about the pinout and the video mode just because I wanted something to you know show and change and we've got blink up here so you know it's running circuit python and once you've set up your display and if the board comes with the display it might automatically start up doesn't do that yet but it might in the future then it works just like display also all of your display programs will come over and they'll work with like the much bigger display I don't know what the next biggest display is it's probably whatsoever on whatever is on the not matrix portal the high portal titano which I think is like 480 pixels wide or something this one is 800 by 480 and display I always doubling the size of the pixels for the terminal just so we can still read it so second up this is a prototype board that the more sent me that she has shown on some of the streams and it is running a square 720 by 720 display and this display is just so so sharp I love it and so those are the two displays that I've got running and the two boards this is a development kit from expressive it's the ESP 32 S3 LCD EV board version 1.4 you read that right there and it's got this I don't know if it's a 480 display or a 720 display and this one has a touch screen so I'll be working on those next this board starts with circuit python but the display doesn't come up yet and we've got other fun displays again this is stuff Lamora shown before but around display with a touch screen a different square display and then these two bar displays so I mean just wet your appetite and think about what kind of projects you're going to put these in this I don't know I'm imagining like a virtual vending machine because you could have like all the different things here and I don't know why you would make that but why not have a virtual vending machine maybe you know you'd have a row of spoons up here and I don't know corn flakes or whatever you like to eat and just just a little silly thing but I mean so many ideas yeah so anyway that is what is up there is a pull request open that adds this functionality that adds these three boards just the tiniest bit of sample code yet but we're really excited to get started with this in circuit python yeah I'm super excited it wasn't great to watch you work on this and I've definitely got some big display and weird project ideas brewing you were telling me about one of your ideas what was that oh um I've had this idea for a bit that uh the terminal from severance where they do the macro data refinement I I'd love to do a remake of that where the little numbers are swirling and maybe we could actually interact with it to do that so with these bigger schools maybe maybe yeah I I want to see if we can do like a live moon phase on this I think that would look so good we talked about um maybe doing an uh a digital analog clock where it's an analog clock face but digital yeah you know a mars clock could be fun yes since the mars day is a little bit different I don't know exactly how you display that but an analog mars clock yes I I'll see it's gonna be so great all right just so many ideas it's a lot of fun yes well thanks so much Jeff for coming by and all right work on this and looking forward to seeing it it's uh fun to be back I haven't been on for a little while but this is why this is why all right have a good one all right next we're gonna hear from phil b hey hey how's it going goes good he mentioned live moon phase clock you know tonight is a uh a blue moon they call it yes it's not actually blue colored it's just a rare occurrence two full moons in a month yes so go look for it in the sky uh tonight anyway um we did a project it was a few years ago was a 20 die that you roll and it announces the number that it landed on using an accelerometer no it's not great balance it's it's a project it's fun yes um but there's like five PCBs stacked in here at weird angles and uh we decided to revisit it using the uh prop maker uh feather and it turns out there's just one board needed now so five down to one um I won't go into the project because it's going to get covered on ask an engineer and there's videos and everything but the guide is live yes um but I did want to mention um this clear case that looks so good this was done with the the PCB way service and we have we have a guide on how to use the PCB way service um I actually did this I mean it's really cool because I remember there was a period in the 90s where like everything was clear yes you know it's a little reminiscent of that um but I actually did it it was for diagnostic purposes because the board sits at this weird angle inside there and I was having trouble visualizing the vectors on the accelerometer and it's like if I could see the board and the case at the same time that would really help me that's awesome yeah yeah so um but the the clear printing from PCB way is uh it's not the cheapest thing but there's a price break at two so it's like might as well get two so I sent one off to no way and uh built one for myself um don't know what to add there just then yeah like I say it's that 90s nostalgia thing it's very cool and they also have a thing where you can um have a pantoin color so it you can do like the kind of like a shaded color um so it's like still translucent but it's almost kind of like the like the nintendo I think it was like n64 where all those like fun like see-through colors you can yeah I think that would actually be even better because the numbers are hard to read I'm gonna I'm gonna hand paint into the numbers they're kind of recessed slightly so I will paint the numbers but yeah with a a tinted uh but still translucent dye that would be like perfection yeah so maybe I'll do an upgrade on that oh excellent definitely I'll post a link over on discord with the the new guide awesome thanks so much philby and excellent job on the code for that all right have a good night enjoy the blue moon yeah all right now we're gonna hear from some folks in the community we're gonna start off with deshipu okay hello uh so I have two things to show first one is you know about the pie gamer pie badge all those game consoles you can program with circuit pattern you can make your own games I've been working on something similar for for a long time I I generally make them compatible with the other fruit products but I try to make them a little bit nicer for myself okay so I have one that is uh it's it's called micro game 22 very cool micro game you game you it's for micro and it it has this nice three inch uh display so basically it's uh like pie gamer with a bigger display yeah uh it doesn't have all this nice stuff that pie gamer has like accelerometer no pixels so on because I want to focus on the games and it doesn't run from a lipo it runs from normal batteries okay because of that I added uh a boost converter to it so it can really use all the voltage from the batteries like they they can drain them dry basically to zero for to zero volts and of course because I also like this 90s aesthetics aesthetics I have a laser cut case for it excellent the patterns are just uh glued from the backside with with transparent tape so that that's how they are and it looks like ergonomically it's a nice placement and size for the buttons too if you're holding right I I I basically made made it fit my my own fingers and it has usb c excellent so I'm the built-in speaker uh here cool so pretty nice eye to see uh amplifier in there yeah yeah right for this camera but maybe I can show um yeah if I kind of angle it you can see there is that that's an adventure game I I've been working on very cool and that's in circuit python right of course excellent right so that's that hopefully I can get it so I switched to easy 8 EDA uh for for designing so you can now order those things already assembled with one click from from their cpcd so I hope to make this available for for that so people can just order the displays are not there so you would have to add the display yourself but mostly everything can be assembled cool and the second thing last time I was showing my tiny robots tiny crap robots so I upgraded one of them oh cool a little bit so I thought okay I need to add some driver in there and here's a switch we can switch it on and of course because this is a demo it reveals us to work yay so you have to believe me that it's actually working I believe you I believe you it there are animations I have uh uploaded so I can show that later and uh yeah it's it's really tiny it fits in your hand if you lose those two gram servos nice which appeared on an express recently so they have really fast for for a servo yeah I love the art too yeah and and the PCB art on there of course because I didn't want to make it look like an animal because uh that's kind of dishonest to make robots that pretend to be leaving things so uh as a mecha thing and the battery kind of looks like a backpack yeah that's cool that's great that's also yeah so that's all I have and of course it runs circuit byte love it all right oh it works there we go no idea why it didn't yeah so if you put it on the floor it will work right yeah cool okay thanks so much for coming by and those are two really awesome projects thank you have a good night uh next we're going to hear from Gary hi everyone good new Gary in Australia hey um so mine's a little different I mean now normally making projects and stuff and I'll just show you some of the things that I've done but the problem that I've gotten a small little tiny little study that I'm working in is always having mounting space where I can put up my projects so what I'm working on is something called a hex tile so it's like a little hex hanger and what it is is uh all interlinking hex tiles that and these panels all sort of link next to each other um and what I do is this gives me a whole lot of negatives right so I can get little mounting posts that I can mount straight into it and it just fits in gravity so if I don't like where my uh projects are I can just move them around and having this tile styled over the wall where I just call it put a hex on it I can then put up my uh projects all over the place so I'll just move the camera around so you can see my progress on what I've done so far so you can see is I've tiled the entire wall and just by I've got even little shelf going up over there with sitting on some mounting posts and I've got even my Tron legacy baton batons that I've made as well so instead of having screws all over sitting in the wall I've just got this massive panel everywhere and as you can see over here this is my little LED widgets that I'm adding in as well so I can put like what I'm going to call a hive mind so I can just have some light going in it as well so this way instead of having all the shelves up I'll take the shelves down and I'll just put up these uh panels and tiled the entire wall just put a hex on it and yeah the next day from the is uh sorry I'm just taking a bit of time for the camera sorry about that um is that I um in these uh between the tiles as well you can see there's a little channel running and that's just big enough for me to have some wiring in there you can see every cell is an entry or an exit point so I can run wires between each cell as well so I can have like USB power points or you know I can run power to each cell if I want to so I can always have electronics or lighting in the back there to something like that as well so there's something extra just to that's super cool it's really impressive looking um have you do you have it posted up on printables for folks um so it's just something new that I've just worked on so I just thought I'll first bring up because I know like even on a 3d print and I've got a little proof so that I've got but to print one of these takes six hours which is a bit much so I know I can put them up but I was thinking of doing is just getting the injection mold and having them done for a lot cheaper so if they are people interested then you know I can take it that way I'm not trying to market anything I'm just saying I mean even for myself doing these are about what about 12 panels at six hours each takes a bit of a while takes a bit of time so I'm seeing if there's any interest and see how we go from there but yeah very cool thanks so much for sharing and as you work on it definitely come back and show us how's going well do thank you all right have a good one so all right next we're gonna hear from DJ Devin hello I'm doing okay I hope you having a good night Liz I am I had a matrix portal S3 with four five millimeter pitch panels very cool and I wanted to show everyone the difference and the importance of bit depth so this is a five bit depth basically whenever you make an image for display IO it's you know an eight bit image with eight bit depth and the most that you can realistically do with the matrix portal S3 is six and this one is on five and as you can see there's a lot of scan lines it's not very pretty to look at so if I drop it down to four and you'll see that the background image will kind of have like you know that two bit color you know as you drop down in bits the image quality gets less and less and less and then if I go down to three you'll start seeing that there's less artifacts but it still crashes that's it that's an issue with the with the latest matrix portal that they're still working the bugs out kind of let's see if I can do this one and you'll see you'll notice that the scan lines with three bit is you know almost non-existent it's much easier on the eyes you get a little bit of a background image but as you can see the background image detail goes drastically down so these are these kind of matrix panels are really for you know two color display so I'll show you what that looks like with two color and all I'm doing is dropping the bit depth down to two and it automatically makes everything solid color there is no more background image automatically it just doesn't have the colors to do it so then you get this you know massive black you know background with the pretty you know bright colors and that's on bit depth too so there is a big difference if you're planning to make a large matrix portal panel project that the bit depth becomes very important yeah all right well thanks for coming by and showing us that kind of step-by-step thing it's going to be I think good and this we'll see the comparison this runs on a bme 688 itc semisensor so all of these values that you see here are real excellent all right thanks so much DJ Devin all right have a great night everyone thanks all right next we're going to hear from Sophie hello hey how are you I'm good thanks how are you good good good um I just I don't actually have a project that I built from scratch I have something that I recently repaired which is this vintage 1960s tape recorder that I bought I've been super cute kind of interested in real to real machines lately and so I really like these from the 60s I'm just going to come down here so this is like the kind of tape recorder that they would have people would have used like on their desk just to record like voice memos and maybe like voice messages wasn't really intended for music or anything with like high audio quality okay I'll show you where the little tapes are so um so yeah these are little three inch tapes and this machine was made in Japan so actually these are more like three and a quarter inch tapes because it's like millimeters instead of inches um but uh when I got it it didn't actually work very well um there's two motors in here and I'll just open the back later and show you the motors but um one of the motors didn't turn very well the um volume knob was really scratchy and um the there just wasn't any sound coming out so I took it apart and I replaced all the capacitors and I cleaned out all the potentiometers and actually got it working so that's amazing see if you can hear it I'm gonna just play something I recorded yeah testing testing just doing a test talking into a microphone that is going into my new tape recorder let's just hear what this sounds like that's so cool so um and you can see where the rewind is really zippy yeah it's just like so satisfying um to use this thing and I'll just it it's so simple it's all plastic really and some metal parts yeah but if I flip it over onto the back you can see the back just lifts off and you can see the the back yeah this is like kind of a fun old circuit board um it's all screwed in right now and it is actually really hard to flip it over without desoldering some of it so okay yeah unfortunately can't really show you the front of it but um I can show you some of the capacitors that I didn't end up using and I was fortunately able to source the capac the replacement capacitors that I needed locally oh that's great yeah we actually have a pretty good electronics shop just in town so I just popped over there with my shopping list and I was able to get what I needed but the capacitors are axial capacitors um they're old you know these are really vintage style capacitors yeah before they ended up going to like radial styles so that you had less like footprint on your PCB I guess but this also has kind of an interesting battery layout so what I learned is um so this is a twin motor um design a lot of these only have one motor and then they have a belt but um this one actually has one motor for one motor for forward playing and one motor for rewinding oh I see okay and if you look at these um the batteries the C batteries drive the motors and the AA batteries drive the amp so two of the batteries drive the rewind and one battery drives the play motor so it's literally just double the speed for rewind as it is for play wow okay that's cool yeah and if you um so what happens when you turn the switches is um this is known as a rim drive style um um tape player so versus uh a pinch roller and a cap stand style so literally each motor is touching the underside of just take this tape out so the motor is actually touching the underside of each of these plates so one motor is touching here and the other motor is touching here and when I um move the switch it literally just turns one motor on or the other motor so it's known as a rim drive which is not ideal for keeping constant timing but a pretty interesting mechanism yeah that's really cool yeah so that's my new little obsession love it and that that's so cool that you repaired it and that was just an excellent walkthrough demo so thanks so much for coming by with that thanks oh one thing tomorrow I'm going to be on a stream to launch the new make issue yes which is out now um and it's it's a really cool issue it's all about cosplay and there's tons of people who you've probably ate a fruit audience is familiar with in here um and it's tomorrow I guess on the make magazine um I think it's on their youtube channel it'll be at 7 p.m eastern all right uh definitely drop a link for that into the live broadcast chat um all right thanks so much for coming by sophie thanks all right and now we are gonna have mark play us out hey mark how's it going hello it's going great you good good so I don't have something new yet to show my lightning detector works I've now had a storm a month after I built it so I could uh that as I mean I told everyone to thank me for the nice weather say like you prevented all the lightning that's exactly except the storm that hit us was fairly bad and then but it it works but the case for it is still work in progress but while I was building this actually came across the board that got me into electronics eight years ago so I hope this sort of shows this is an intel Edison yeah I remember those so this was from about 2014 2015 um that I was at a conference in San Diego for Gartner and they were talking about the internet of things which they still are eight years later I'm sure it'll be here any day now um and there was a workshop where they gave these out to build uh so I fell in love with this and instantly there was uh some seed studio sensors they gave us with it we could hook it up to twitter through wi-fi at the time oh cool um and then they gave away all these boards by lottery to uh anyone who attended so I was lucky enough to get one of them nice uh which is interesting if I'd never gotten this board I'm not sure where I would have ended up funny how that stuff works out yeah so I just came across as it's no longer supported what I did find interesting is I just received this much smaller teen c 4.1 yeah um to play with synth IO that teen c has all the power and more that that intel Edison did all the years ago but now in a much smaller form factor with a lot more ability to do things with it yeah it's it's amazing how much the hardware has changed because even um we were talking about with the d20 that philby just worked on with uh rose brothers and then ice worked on the eight o'clock that philby had also worked on how like it used to take like five huge boards and now like it's everything's getting smaller and more compact so exactly I I was trying to build my weather station that I that really got me into electronics on the the Edison board but it was still running linux there was no way you could run that low power yeah there's just a lot of lot to overcome versus that's how I actually sort of found out about Adafruit I was searching for alternatives got a feather m zero and from now I'm here history yeah all right well thanks so much mark for coming by and showing that and we love that you've become such a big positive part of the community and props to you your community member when I first showed up and I saw you there every week and I was like I want to do that so that's a great message to anyone else watching who hasn't been on yeah I full disclosure like I was terrified the first time I went on show and tell like shaking and but it we're very friendly I promise and we just want to you know see your projects and just let you become a part of this positive community so thanks so much mark yeah thanks for it all right have a good night and that's going to do it for tonight show and tell thank you everyone for coming by super awesome projects in just two minutes we'll be asking engineer with lady Ada and Mr. Lady Ada thanks and have a good night bye
