 All right, lady. What is this everybody and welcome to show and tell it's me lady. Ada. Mr. Lady. Ada We're here at the 8 foot factory where it's nice and quiet because for the next 30 minutes We're going to check in with people from around the community and hear what they're up to We've got a whole bunch of people lined up So I want to get right to it starting off with Fridici key J robot and the human companion J Robot head plus That's a good one. I would take that live from you. Yeah This is my the head of my current robot working on orbit This is the virgin two of them. I did virgin one for silicon Which I have the old head right here so you can kind of see the space between the two The bodies in the corner and I'm still working on that but this is a project I want to bring for super con and I've been slowly just printing it out standing it down and building it up Done this morning, you know, it's like, oh Orbit's the perfect name too. That's a good name Oh, yeah, the first one designed to be more because I always go in my head with this I decided more to be more of a like help around the ship thing and this one's a bit bigger So I'm designing it to be more around if I had to venture somewhere. I can bring this robot with me You know, yeah, this is like the you know the base spot. Yeah, pretty much like it's definitely Not a shoulder bot. It's too heavy to be a shorter bot like this this thing is Man See it's too big for all that but it's perfect But I'm building it for and it'll be nice to see it roll around once the body gets done. That's so cute I love it's already got some personality to it. You know, so we're a Media sponsor and a regular sponsor at super con. So we'll have a couple things there and then I think some of our team is gonna be there as well So for folks who don't know super con hack-a-day events back this year Check it out. I think it's a first week in November Yeah, I think November 5th for 5th. Yeah, we have to know what we're doing Yeah, no, I'm very ticketed. All right. Well, thanks so much come back and if you if you're around Before after super con come on back and let us see the progress of orbit. Of course And orbit you can bring j by to yes All right next up JP what you got going on Hey, so this is the the the conclusion of this project been working on for a few weeks now I've got the final case put together for this split ortho keyboard and it uses two of our PCBs. It's it's super simple It's not like a hand-wired You know lots of work. It's actually press fit push keys into the PCBs and now I've got this working with sort of a not quite retractable, but you can you push the cable in there and use it as a Ergonomics split ortho or you can feed that back like a government agency Like like the IRS like send audits visa or it's just like it has a governmenty Feel to it explains a lot because it's impossible to type on them So not used to your past ortho linear thing. Yeah, so every tech company changed their logo to like a shade of blue for a while Remember that they all just like yeah, I mean buddy I just don't love that that this is a beautiful Bank teller like a bank teller in the 70s like you pull in your car in the station wagon You put your thing through the tube and then you'd be like here's a lollipop get out of here and they're like Yeah, you wanted to grab that sort of adding machine that had those yeah, there's nothing about it so this is the version I did with a combination of 3d printing for these walls that have Organic shapes in them and and I wanted to press fit some Brass threaded inserts in them and then the top and bottom or laser cut acrylic I put files up on Thingiverse and linked into the guide. I'm working on which should be out pretty soon The both versions so you can do a version that's entirely 3d printed, but I never like to do Flat stuff in 3d because it's yeah, it seems like a waste and bear the laser cut if you have a luxury or you could use hand tools or CNC or something to make this part and it could be acrylic could be Some wood kind of up to up to the user how they want to make it so the files be up there and the code is up in our GitHub it's all circuit Python super easy to customize. I have a little config file that people can change the key Assignments in it's not using QMK because I thought it would be a little bit Tricky to get the dual TCA 8418. I squared C as each side. That's how each side is Matrix and over a square C sending to one QT pie that's over here So it's its own homegrown thing, but similar. It's easy to configure with one little file So that's my split ortho linear keyboard and the guy will be coming out soon And then tomorrow I'll be working on possibly a Halloween project We'll see if I score the item. I want to get it one of my local Halloween stores this evening So I it may be spooky tomorrow. Okay. Thanks so much. All right. Nice work. That's what color matching the acrylic to the Keyboard keycap. Thank you. All right next Hey, Jeff, what you got going on? IRS technology Okay, you're muted. So maybe um, yeah, Jeff We want to hear you. We see you I've been in before with the Apple 2 floppy drive and considering the stores like a hundred and forty K or something It's like it's kind of big for what it does but recently My friend has given me some computer hardware And so this is the internals of a Commodore 1541 floppy drive from about the same era and instead of being like nine inches long It's like 15. So there is a lot in here And I was just gonna power train with that capacitor dive into this a little bit. So, yeah It's got first of all a whole 6502 CPU in it Whereas the Apple floppy drive has no brains hardly at all, you know, the PCB is this big Yeah, it's got power rails for five and 12 volts. It's got like a 16 megahertz Crystal in here for something huge. I've been actually like a crystal to like you opened up It's like you can see like And I mean this thing was power hungry and hot in its day because there's a whole transformer back here Because you know, that's how we did power supplies in those this is like the Cadillac of Floppy drives. It's like it's huge. It uses a ton of power A lot But it looks good And then and now like this floppy disk mechanism, it looks positively tiny. This is an alps by the way floppy drive mechanism and this was slow and awful and I don't know if this one even works because I don't have a computer to plug it into But I just wanted to kind of give the juxtaposition from apple made trade-offs and Commodore made trade-offs and I think Commodore picked bad Bad trade I think Commodore. I mean look, it's it's it's a little bit overbuilt in my opinion But you know, that's that's why apple too, you know, did such a good job with their floppy drive and you know, the floppy Design that was dead was was renowned because it is so minimal like he just cut out everything that wasn't that, you know explicitly required and also had um copy protection schemes that were built in because of the um You know, uh simplicity of the design, you know, there's the little little hacks you could do so Yeah, I mean, but it's it's interesting to see how they did this but that is there's a beast Well, I'm not using a Commodore phone. So apple did some things right, but I would like to be using a Commodore phone I mean, they were cool in other ways, but the floppy drive was not it But anyway, there it is. It's like all right. Oh It was a little deceiving because the capacitor when your hands aren't there. It's like, oh, this is like a tiny This is oh, yeah No, this is like you might injure yourself who was charged up. It hasn't been charged for 30 years All right All right, cool. All right, Erin How you doing welcome back to show and tell what you got going on this week Um, I have a couple cool things to show. Um, let's see if I can get my screen showing here all the buttons First of all, I just did a tutorial on these last week. These are jellyfish and uh, I installed a whole bunch of them I have 30 of them up here at a light festival in open california autumn lights festival So, um, they're running W led and all synced together and playing animations and it was just really Set them up so people could walk underneath them. Um, it had like whale song playing the background and everything made it A whole jellyfish garden. You made how many 30? Uh, there are 30 so far There's going to be 50 total when I'm finished and I'm going to be installing them at the mermaid bar in sacramento All right So the guide you made is like it's battle tested because yeah After you just after you make 30 jellyfish, you're probably good at it. You're getting first jellyfish is the best Yeah, and then uh speaking of the mermaid bar the other project I've been working on this week as I made a new light up mermaid tail Um, so I've uh, I've had a light up mermaid tail mermaid glimmer She actually got written up and make magazine several years ago, but she is just done I booked a mermaid show for this weekend and I tried to repair her and I you know Like trying to make lights that work underwater is not easy. Yeah. Yeah, so it's great. Yeah. So is that someone else? That's me. Okay. Wow. Yeah, so I have been um, I'll play it one more time because fun mermaids But it's so cool to see it underwater and it's you're you're so good at moving it in an organic way Yeah, it's a lot of fun We're doing a big halloween show down at the five bar in sacramento and we're gonna do a bioluminescent theme So looking forward to that should be a lot of fun and um, I'm planning to write up a tutorial about just basically making Lights work in harsh environments Uh, like if you want to build something for burning man or you know anything like that where you it needs to be outside It's going to go in a difficult environment. We're in aquarium suspended in the air Yeah All right, I can't even imagine the bill that required to Have a water tank with a person in it I like that we're writing a tutorial for like david blaine It's like you need to light up underwater under the ocean on top of the mountain On a hot air balloon. We're airing man. How to do that? Yeah, it's 40 feet long. Uh, one piece of solid glass across the front It's a really neat a neat installation in there right on. All right. All right amazing excellent work Uh, let no one say the aid of fruit tutorials are uh, uh, Boring All right. Thanks so much here. All right sweet Now i'm page ro Would you get going on this week? Wow, that was amazing. I swear that kiss at the end looked like a heart that she like blew How did probably was on that? You know, it's like it's like blowing smoke rings. She practices it to make it look so So cool Yeah, so this week uh brent had a really cool idea on doing a whipper snapper like soil sensor node so The way I was gonna do it was totally like this this was like really genius the way that he has just the stem of soil sensor just having it be the anchor that like holds the battery and everything in there so inside Just a water resistant case. Uh, we have the qt pi 32 s2 We have the new passive hub on there to make room for bunch of sensors like light sensor on here And then on the back we have the scd 30 so uh Measuring the humidity temperature co2 and then have the battery gauge as well So you can tell when to change out your battery nice little Snap fit together design. So let's like air in we have the like gyroid infill So you still get like sense of what the environment is going on This was super handy this week with the temperatures dropping down in florida was able to figure out Oh crap, I need to put a tent up around my plants I could like measure and see that there's no leaks in there to see that the temperature was still up And the humidity was good for everyone and uh, yeah, just a simple little uh soul sensor node And 3d hangouts we show how to build the upper separate dashboards He can have like beautiful graphics on showing, you know, all of the levels of uh your environment And along with that I've been able to figure out like the characteristics of you know, all the rooms in my house So if I ever needed to bring anything in I would know like, you know Put it in the south facing window where like what which room has the most humidity was in the bathroom Which is you know, my surprise So yeah, cool little soil sensor node if you want to just get the characteristics of the humidity environment of Whatever you're growing Okay, and we'll be showing This video and then a speed up this week on ask an engineer So come on by tonight everyone and see how it was made right. Thanks so much All right next up and what you got going on this week I finished my second halloween project I've always been a scooby-doo fan since the first incarnation and One of the ghosts that I really liked was called the spooky space coop It was kind of like a skeleton in the space And uh, he had this this laugh. It's very unique laugh. So um Seeing a space helmet. I didn't steal it from just north of here. This is from that popular Halloween store that everybody goes to so let me just plug this in here and turn up the volume So Obviously, I can uh improve on him a little more make this A little more like sound reactive or something, but it's really easy. You um, he uses a circuit playground express and uh circuit python, um, I Got the the the ghost sound and made a wave file and put it on the on there and then I just take the audio out into a My my trusty little ancient radio shack amplifier You could have an amplifier board or whatever you want whatever you have And uh, it's really kind of fun and I can put this in the window and And uh scare all the neighbors Like how you're doing it a geographically Correct for the area. So, you know space coast you have space ghost And uh, I I saw a comic book once and it had a skeleton in a it was like an astronaut skeleton and everything And uh, it was kind of neat because you know, you don't have to eat or breathe So, you know, you can go on longer trips and stuff like that. It's kind of a good way to solve the whole Yeah, space ghost can can can travel to mars. Yeah See zero. Um, we can suggest it to those people who are trying to get to mars and see if we can I'm gonna email NASA tonight dear NASA. I think you should send skeletons to mars. Okay Thanks so much, Ed. Thank you. All right, Liz. What'd you get going on? Hello, uh, so started prototyping. Um, a quick heling project where it's a bat. Um, we've got a circuit uh playground express and two servo motors Um, and so they'll have two wings here. So we'll be flapping right now I just have the neopixel um test code and the servo example from uh, circuit python, um, essentials guide running to test um and did like a test of it tonight And it's also using the alligator clip servos. So it can be totally solderless and quick for folks to put together Yay Yeah I think enough time is passed where bats are okay. I remember the first year when COVID happened Everyone was blaming bats and pangolins now. Uh, we just blame ourselves. Um, so it's probably perfectly okay Yeah, I've done some other like 3d printed like classic Halloween props And I'd wanted to do a bat and then with the code of it stuff. I didn't yeah, everyone forgot about that I remember when they're like, it's the bats It's the bats, but that turns out I don't know. I don't think it's all right. We really blame those bats I have to blame someone. Okay. Well this bat looks very nice. We're not gonna blame ourselves It's a friendly nice bat. All right. Thanks, Liz. I keep it spooky. All right We're gonna go to dj divin 3 and then we'll go to Mark dj divin 3 Yeah Okay last week uh came on and showed off the uh, the social media tracker project which only had the youtube uh working and now I've got twitter and github And coincidentally uh this morning for lady eight is expressive dev con talk. She actually used the uh, the github I noticed that Because I wrote the same exact code at just about the same exact time you were giving that presentation And then I also have a build for the the goggle kit. So I got that working So once so with this I used the mirror tent film Uh that I picked up uh from uh becky stern's tutorial And then I also put that on one side of this to give us a kind of a diffused look Yeah, uh Instead of being able to see right through it, but I wanted to make this so that you could actually wear these and see through it Obvious I'm not gonna put this on the side of my head. I I just didn't have the the small one recharge Yeah, you can also just get a really long cable and then Put the battery in your pocket or something And then I also did uh this All right, you're busy. Spooky eyes. Yeah. Oh, yeah Yeah, mark is up next mark mark. I thought about internet famous this week for all the eyeball projects Yep, uh, and uh jebler with all of his tandy candy. Oh, that's a great name for his halloween. Never mind So that's yeah, I've been pretty busy And I've only got one more left to go and I'm not sure what I'm gonna do uh, I wanted to ask is Can can I plug into uh, adafruit discord somehow or is that only just yeah, I think people that own the server No, I think you can use um if then this that or I think there's webhooks like there's ways to do it where you can get information to and from discord, um I was thinking, um the amount of online pythonistas Yeah, you can also the you can also do a neat little thing. There's a uh widget that we use in our newsletter that'll grab the latest, um Whoever's online You might be able to like parse it with circuit python. I think there's like a jason file or something poke around Yeah, I'm pretty I'm pretty good at apis and jason parsing. Yeah, I don't yeah You know, it's one of those things where I'm gonna search for it. It's gonna be me writing about it So just search for discord circuit python I remember somebody did something yeah and like users and I think we had a little like pipe portal project that showed that Okay, uh, thank you very much. That's all I got. I like that the goggles could potentially, um work with the eyeballs You could put the eyeballs in the goggles. Yes, and I did mention that and I was thinking of lars when uh, yeah All right right on. Thanks so much. Thanks j Last at least all right. It's mark. Hey mark I'm gonna play your video in the beginning of asking engineer because I saw it go by everywhere It's so funny everyone's addicted to watching the eyeballs. So good work with it that totally surprised me. It was just like a Little clip I was doing while I was working on it and also my phone wouldn't stop vibrating so But I did get it working On two eyeballs, uh Let me see if I can kill the brightness on my camera at all Oh, they're very bright eyeballs. Yeah You can probably want to have it be brighter because then it'll Not if you can make the breadboard go closer to your head. You could probably make it look like they're at your eyes Right about there It is tough to see and we see the pupils Yeah, you don't see the the irises It looks like, um, one of the creatures from the muppets. Yep. Yep. Yep. Yeah But right before show and tell I need to restart this because Too many things plugged in at once um, the problem is is what I had that running on of course was a m4 and You can't get them. So I have a couple of them That I was able to use so I thought well, I've got lots of rp20 40s Um, so my whole goal was to try to get it running on a pico, which I'd sitting around Problem is I didn't realize a lot of doing this on our do we know Wasn't written like all the libraries that the monster mask project used like the arcata library Weren't designed for the rp20 40. It didn't even exist when the libraries are written Yeah, so that led to a lot of other things but right before show and tell I have the eye working on an rp20 40 Yeah, we even though even though arcata was you know, because we were doing a lot of graphic stuff for the samu 51 You know, you can extract the the code that actually does the Eyeball stuff for like the halloween m0 or m4 like you can make it Ported it's just really tough to get because you have to have the dma optimization. It's just not easy Yeah, I dma. I was working on literally hoping it would work right before this And commented out because it didn't yeah the flash storage had to get working It's it's really a challenge. Um, I don't tell you we just haven't looked at it. You know, oh Yeah, and it was one of these things that I went into thinking Okay, I'll give it a little bit of time And then I kept getting just enough success that I couldn't put it down Yeah But it Actually, and if you have the eyelids on this it runs all right Yeah frame rate, but I still want to get the dma working because I hope that'll speed it up If you do it Marklops going on here like a cyclops I think either i or phil b did the pr to add spi dma support. It's in there In the rp20 40 core I just don't think that if gfx uses it and we don't it's just I don't it's and you know, the eyeball code is very optimized Yeah, and I've spent a lot of time reading it and I did look at the rp20 40 data sheet on spi So I've got a pretty good idea of it now. It's just to get it in and to find out if I'm going to configure correctly Okay, well, you've got a week. All right I will try my best. You'll do you'll do so much mark Yeah, we're in the beginning of ask an engineer. I grabbed your video and I have a little soundtrack we put Underneath that I thought was fitting from a song that we did a while ago. So thanks for putting it out there I saw a lot of folks that uh got interested in like how did you make it? I want to do that What can I do? So this is this is the way people people want to learn electronics and code when they see stuff like this Thanks for sharing No problem. Thanks for writing it in the first place. Yeah, thanks mark All right, everybody that's our show until for the week this week finished right on time We're here every single week some 30 p.m. Each time long's running live show until On planet earth It's true. We'll see everybody on ask an engineer in just a few minutes See you next week. Thank you for making this the best half an hour of our week every single week Bye everybody
