 They did what is this? Hello everybody and welcome to a super spooky Halloween theme show until we'll have a couple spooky Halloween theme project It's me lady. I'm Halloween here every week Me lady either mr. Lady Ada wearing all got black carrying the eight fruit factory where we're doing all the engineering and manufacturing kidding But right now it's quiet because we're gonna check in with everybody Who's gonna buy the show and tell I'm gonna have a bunch of folks from it for community and the wider maker group come on By anybody's invited to the whereby check out our discord for the link Come by this week or maybe next week. We'll be here for another 20 minutes or so All right first up JP what you got going on? So I've got some Halloween stuff. This is something I like to do I did one of these last year Which is go to the Halloween store Find some sort of electro mechanical maybe audio Maybe sensing type of prop take it apart see how it works and then take over some of its Brains with a microcontroller. So this year I have this cool Ouija board and it uses a motor and a linkage and magnets to move the Little whatever you call it around you don't have to get there with your friends and pretend to be not touching it It just runs in a pattern and at one speed. So what I want to do is take it over So I've got a feather nrf 52 840 here So I can control it over Bluetooth and I've got our little blue fruit app here and I also have a little motor driver So first of all if I want to drive the motor I can hit a button on here And send it somewhere and since I'm a little bit. I can also stop it So I can't send it to every letter on there, but it makes a sort of figure eight around a bunch of Letters so you could maybe have something set up that you wanted to play back for an effect I can also reverse the direction. So now I can head back the way I came and not always go in a loop So I can go to yes, and then I can maybe keep going in that direction Pause it over G for some reason suffer like G did And now if I want I can also turn on some neopixels that I have in there I haven't done a lot with what they're gonna do yet But I've got a strand of neopixels in there that I've Taken over so the guts are actually kind of discarded off to the side those are the original guts in there I don't need pretty much any of that anymore. I've got my Feather there motor driver a little strand of neopixels They had some LEDs in there and I checked those because they were just white LEDs that were sort of blinking So now I've got RGB neopixel LEDs and that's their original motor and they're cool little linkage thing You can see that running if I hit play on it now, so the Yeah, it's a really cool linkage I took it apart fully on my show last week So if you want to you know wants to go back and look at the the live stream archive You'll see what this looks like when it's fully taken apart. It's a really clever mechanism And then the one other thing I figured we worth trying is other stuff. So There's a magical quill So I've got one of our actually a little m4 threaded Magnet feet that come with our RGB matrix displays that you can pop on to something Ferris and I've just grafted a Leftover feather actually I came off of my my untitled goose game costume. I had a remnant of it left over so This looks scary It's pretty scary I saw it was I think it was on like social media there was Apparently a grandmother who knew she was passing away But she was like a cool grandma and she gave cards to all the people that were showing up at her funeral That said keep in touch and it had a little Ouija board and a picture of her Gotta have some humor at the She wins Thanks, JP. All right, so you'll be showing off some of these things and more on your show tomorrow Yeah, I might be adding some sound to on the more suggestion, which is yeah, that's a good idea Spooky spooky sounds. All right. Thanks so much. Okay. Hi. Thanks JP. All right, Liz. What you got going on this week? Hello this week. I worked on a bat project Yes, so guys circuit playground express and then to servo motors attached with alligator clips and for demo purposes I made it so that the switch Should be turning the servos on One It was just working it was This used to happen on like Talksha's in the 70s when they'd have like the animal handler on or like here's a jaguar and I'm like wouldn't work out Yeah, not into it Well, the wings are supposed to fly Yeah, you want to come back to you at a later bat time, right? Let's come back to you then because I think you just Asked you to make code codes you probably went off and did something awesome and forgot to revise it Yeah, hi, we'll edit this in post. Nobody's always gonna see this. No, it's it's working with live animals is always a challenge It's alive that okay. All right. We'll get back to you in a bit What you get going on this week? Hey folks, can you hear us? Okay? Yeah, okay cool Cuz yeah, the microphone's haunted this week. We had a fun time in the In the morning show so we 3d printed some signs and neon signs I forgot to plug it in. Let's plug it in. So this we did three different ones This was a werewolf howling at the moon. Oh, yeah, and we've done some LED signs before but this one uses two separate It can be if you want to be yes, so there's there's the moon and we use the circuit Python It's using the Qt Pi RP 2040 and with the LED animation library We were able to kind of string together different Animations to kind of use the sequence helper to just kind of make separate animations for each individual new pixel strip so Yeah, it's it's got a little hook and the case is a coffin That's cool. Yeah, yeah Ghosts in the background. Yeah, we got spooky ghosts with glasses and a grim reaper with a sight and Shout out to Philby for this idea because I wouldn't have thought of this werewolf, right? Yeah. Yeah, it's pretty cool I like it. I didn't look like finished neon signs. Yeah And what's neat is you know if you wanted to expand this project you could have it So the moon lights up when it's a full moon out you can have sound you can have you know when it's dark out The moon lights up and then it can detect Dogs barking audio Yeah, there's a lot of active as well. Yeah, I'm in there. Yeah, there's many in the case cool So folks when a print went up and get your printer started it takes a We're about 10 hours to print and it's a pretty big one, but we can split it up Yeah, yeah, totally Yeah, but the installation is pretty easy just kind of press fit them into these channels and then just cut the strips along the lines and You can solder them up to an extension cable like I did here All right, and we'll be showing off this video and your speedup that you did on asking June night. Thank you Thanks, folks. All right. Thank you. No Pedro next up paint your dragon dragon, but you got going on It's me. Um So like the internet memes this month is Is this Halloween thing about you know parents, please inspect your kids candy. Yes Album in a candy bar before Yeah Hieronymus Bosch. What is the the famous triptych the Garden of Earthly delights in? Yeah, when there's like demons in my pricks bar, I was in a peanut butter cup once. Yeah, so anyway That's been going around and so Lamar insisted We should devote inordinate resources to you know doing something with this meme. Yeah So with Jeff Epler's help, I'm a sucker for memes. What can I tell you? Yeah Ported a doom Onto a Milky Way bar. That's right This is the pinnacle of technology when aliens land they're gonna bypass CERN They're gonna come straight to your place and they're gonna say finally Yeah, so parents you got it you got to inspect the candy and make sure it's not running doom Yeah, no, actually, it's it's the feather ESP 32 s3 with the tft built in and To make it fit inside a Snickers bar or Milky Way, whatever this is Yeah, actually had to remove some parts off the top of the board to make it a little flatter to fit in here Yeah, and it's not an actual Snickers bar. I actually I did try There it is actually did try hollowing out. Yeah, of course you did a Milky Way bar. Yeah, it turns out that just it's It's really hard to do it's very messy and like people were telling me. Oh well You have to freeze it in a block of ice. Oh And stuff and he's put in liquid nitrogen in a lathe leave it. Yeah, exactly I went on Thingiverse and somebody had already scanned Snickers bar. Yeah, and so I just I used the model hollowed it out like that and You know did a 3d it was a resin print and then painted it. Yeah, to look like that How did you do the resin print? Would you get that done? I just it's you know, whatever the cheap resin printer is nowadays Elegoo Mars printer have one of them. You have one or I didn't know. Oh, yeah. Okay. Okay. Oh, cool Yeah, so that lives in the garage because they're smelly, you know, yeah And then I just painted it to look like chocolate. I have the you know that t-shirt paint. Yeah, I just the right Specularity to look like the it does. Yeah, it's really close Yeah, so and then tuck that inside. So that was that was the internet joke and it's actually doom We did really poor. I mean like there's no joystick, but it's that's actually the yeah, not just a loop that is The actual, you know doom code running on the ESP 32. Yeah All right, well nice work outstanding. Yeah, you you have captured the memes. Yeah Thank you. All right. Thank you so much. We'll be playing the video and talking briefly about this on ask an engineer This is the Gestalt. It looks really good. Good work you jepler. Yeah I mean, I basically, you know, I keep people kept making this joke and so I was like, well, you know We're like, well, we should get doom running and I was like, well, we've got the t-f-t feather I said the ESP 32 s3 could probably do it because we had doom running on the ESP 32 original We just also do a core and I found some Korean hacker who had done not this project But similar they had s3 running doom and I say jepler was between projects. I was like, why don't you go try porting it? That was I think by far probably the harder part was getting that code Both of you did a lot like it's you know, it's two days and we're great to be okay It'll work team effort right right. So thanks so much. Thank you Yeah, like the laser Resin printing and the hollowing the model and then yeah, this is it's a team effort This is um my contribution was just a bad idea. Yeah This is uh All the best of of what we can do in technology right now. Yes, correct All right, I'm gonna go back to Liz and see how and see how the bat stuff's going. Yeah, all right I tried to add quickly um to make it so that the servos weren't on for don't but anyway, um Basically, we've got a bat with um servos and a flaps Yay Yes simple but effective A good project Yeah, yeah, it's quick to print um and because it's no solder Folks should be able to put it together pretty quickly and then um get a really good suggestion of also doing a make code version So you can either do this in circuit python or make code And I added the uf2 for make code if you just want to download it and drop it on the board awesome And a little bit of eyes and bangs is it's cute. Yeah, and then you got the ghost behind you I remember you you pulled us out every every year. You got your little Spooky zone. Yes. Yeah. All right. Thanks so much. All right. Keep it so you got a black cat too, right? Yes, there's two right behind me. Actually. Okay. Good steering is here. Now we're talking Yeah, all right next uh, spooky. Let's go to tim. How you doing tim? What's going on this week? Hello, uh, I'm doing pretty good. I have uh started playing with the pico w a couple weeks back when we got wi-fi working on it I've been working on a couple variations of a trivia Program and so I have one to show but I also want to show how it goes together because it uses the cowbell and it turned out to be Super convenient for putting it together. So I have the Cowbell with female headers on the top of it and then the pico w has male headers And then I just suck some more male headers out the bottom sticking up there and then it can use female Jumpers to just go between the cowbell and the screen. So Everything is all nice and neat and the same length all the cabling is nice. Uh, but it's also all Kind of plug and play I can unplug it and reuse all the parts for different stuff. So that's convenient In the trivia game you get your choice between how many questions you want to do so up at the top there We can change how many questions we want more or less You also get your choice of what category you want Um, so you choose category you click go and then it's gonna reach out to a free trivia api That's online fetch the questions and you get to answer through them with the buttons here. So Neo q plugged into the stem of port there, which is also nice and convenient on the on the cowbell You get to choose your answers. So I'll just click through them And then it will show your score and then you can just click another button to play again if you want So that's kind of the most basic version But I like the way all the hardware kind of turned out and the next Next thing to do is kind of try to design a case to amount everything inside of It all nice and contained in something um Will you be talking about this or showing this on deep dive this week at 3 p.m. Pacific Yeah, so I have I've worked on different variations of this During some of the recent ones and I think we will do some more Stuff to the ui prettying up the ui Maybe playing around with some other things on there This is like an instant lesson plan for so many folks that want to have anyone who's learning Any type of coding you want to like do a game and then you want to have like reach out on the internet Get information and it can't just be like new stock and weather should be something more interesting than that So this is a really good project. Yeah, thank you. I think the the trivia api is really nice because it's free to use It's easy to integrate with and it's like are the questions pretty good What's that are the questions pretty good that they don't learn they are so far. Yeah, there's a few thousand questions So if you stick to the the single categories, you'll you'll see repeats occasionally depending on which category it is If you stick to the all categories, um, I don't see repeats too many too many I also am not so good at trivia is what I've learned by working on this. Okay. Yeah Python jeopardy. All right. Oh, thanks so much. Yeah. Well, you can practice for free All right. All right. Nice next step We're gonna go to dj demin and then we'll close out with mark and some pumpkins. That's right dj demin three what you got going on? Hello Can you hear me? Yeah. Okay. So last time I worked on the uh, the four apis And now it prints out the actual names and I had to modify the the seven segment library In order to get get it to do that. Um, and I put in a pr for that Uh, and that will reach out to each of the subsequent apis Pull down the the the amount of users And including the out of fruit discord, which I kind of cheated on Because you're supposed they want you to use their uh, their oauth But I found the kind of a way around it that the I'm not going to talk about but there's just a way around. Yeah Yeah, is that and so that's the number of users that are currently total users and then users online Yeah, uh, I there's two there's two apis. Um one is pulling the first one was pulling from the svg And then the second one is pulling directly from discord. Yeah Yeah, that's pretty smart And then let's see what else I got here Uh, let's see if I can adjust my camera Watch out. There's nudes everywhere. Uh, yep nudes everywhere. Uh, let me one second here All right, cool. So these are uh, some decorations for Ask Back it up It's a pumpkin and you light up pumpkin and has yeah, it looks a lot better when the pumpkin's actually on No, it's good Yeah, or it seems like I don't know if a flame will change too much. The leds are pretty bright Yeah, those leds are really bright. We can really see the face It looks good It looks spooky. Please be careful Yeah, like this is Okay, so it's got electronics in there That's spooky. Oh right on Wow, that's that's a super intense pumpkin. You know what? You're right. This does look good. Yeah, you're right It's uh, guys, let's still be careful All right for my last project I got this uh cool Skeleton kind of mask looking thing. Oh neat. Yeah, and then from last week I had my eye project, which I just unplugged It can combine this. Oh, yeah. Yay These have uh, lizard eyes that I came up with. Yeah. Yeah, that's great and if I can Shoot that in there just as a demo because I still have until Halloween to get this one done Plenty of time. You're doing great So this one goes in the front there just as a Oh, yeah Creepy creepy So that's all I got. All right. These are excellent project. Thank you for coming by and keeping with the uh, the Halloween theme this week Uh, absolutely. Thank you for having me. Have a great Halloween everybody. Yeah All right mark I see some pumpkins. All right. Oh, look there's a blink of pumpkin Yeah, there are pumpkins everywhere The blinker was one of my last printed ones And if you get too close to the middle one That looks great as funny is it it has the um, like disney attraction kind of look and feel for you know, they they still have these um like animatronics that Kind of look like that. Yeah. Yeah, look very cute. It's a blinking. I think that that makes it look like that It's like a cartoon character Yeah, it didn't look that scary and then and I was like that's an okay look for it. It's Yeah, happy pumpkin looking at you if you get too close and lights up All his friends around him Yeah, let's see. It's something you can buy Whoa, watch out Attack from Canada. I forgot the um The sensor only triggers every once in a while That's a great pumpkin Yeah, I'm actually super happy how the main one and even the blink one turned out Yeah, it looks purple. Is that is there is there a purple or pink? There's the inside of it. Yeah, there's neopixel jewels in all of them So there's jewels in all the small pumpkins The big ones got the quarter Ring for the mouth Yeah, and then the eyes That I've been working on all week to try to get running on the rp2040 Which finally finally worked. I love how it goes to sleep like so silently. Yeah, these turned out great. Nice work Yeah, thanks a lot. It was uh a lot of fun and Now just to get it up for everyone to see on halloween This is totally going to be a for sale at home depot like two years Yeah, we were we were doing predictions on like what's going to be the next um, you know Thing that has stuff from the maker community. That's now available at home depot Yeah, they love it. I mean like they absolutely. Yeah, we were thinking the the Paint your dragon blood trippy leds might be the next year thing. That was also really cool. So yeah, yeah, all right Whoa, whoa. Thanks for having me on today. All right. Thank you. Whoa Thanks so much. Hey, yeah, give it in character too outstanding and he did those demos at the vascon that was well, you now you have it you get add those lizard eyes like dj devon has and you can That'd be really creepy outstanding. All right work. Happy halloween. All right. Yes, dude Okay I'm gonna go with the treat not the trick. It's like every horror movie has that They've asked him. Yeah. All right. Well, thank you everybody. That's our show tonight. That was a good halloween episode Um, but keep coming by of course you can come by next week. It's still it's halloween every single week here um We'll be doing ask an engineer in a few minutes and every single week some 30 p.m Easter time show and tell thanks for making this the best half an hour of the week of our week every single week See you in a few minutes. Okay. Bye everybody. Happy halloween. Bye buddy
