 Alright lady, what is this everybody? It's a tornado warning here in New York state But we're gonna stay nice and dry and doors and get started with a show and tell the most fun You can have for 30 minutes without getting wet. It's me. Lady Ada with me Mr. Lady Ada were in the Aida fruit factory in downtown Manhattan, which is there's lightning lightning There might be a internet internet disruption if there is we will immediately try to get back online But if not, don't worry It's it's the planet is trying to send us some subtle messages. It's Maybe we should look into some things Let's check in with some people from didgeridoo key and from Aida fruit and also from the community to see what they're up to Kevin did you key? You're up first. Okay? How are you doing? I'm doing good. I'm glad to see you guys are safe and the the lightning storm Yeah under storm We finally got rain. We hadn't had rain all summer in Minnesota, which is very odd Our lakes are starting to dry up. There is only like 9,000 lakes instead of 10,000 There seems to be a it's either there's a drought or it's a flood now like pick pick one sometimes the same week Yeah, you know, it's really upsetting. It's the first time in my life that they have banned campfires You know, it's really too bad. All right. Well, so what I'm showing is I showed you a little bit of a digital campfire now You know, I should have done that I should have created a campfire on this Matrix portal instead of what I did. Yeah, you can still do that Yeah, we talked a lot about air quality last week And I spent more time than I'd like to admit researching air quality after realizing how quick my when I start talking You can see the numbers jump up just for me talking and getting close to this It's pretty amazing and then I decided to take this thing and add it and get it internet enabled So it's now reading the time off the internet and I'm planning on continually adding things to this I want to have weather on here so I can tell if it's a thunderstorm like you guys are having or you know It's just one step at a time But air quality seems to be a big thing these days and it's it's really interesting to read How important it is and how quick just co2 can fill up a room if you're just talking Yeah, well, this is you know, if you can't measure something you can't approve it But now you you're measuring something real time so you can actually improve it. Yeah It's it's insane like even now just setting it down it already dropped down quite a bit And if I start talking into the sensor that it'll fill up and Yeah, it sounds like almost no air movement in your room. Yep Okay, so I did a little research and I kind of revamped my room I added more a bigger area intake and you know made sure the vents were open instead of closed and It was really really interesting what you learned from a project that you were not planning on learning Yeah, and and luckily there's not a global airborne virus that Luckily very true. Yeah, but no, this is a side effect Well, there's a good thing with this So we use these air sent we use the same ones. This is a different project and in places that are Have good ventilation and transmission rate is lower Co2 is one of the things that you can look at if there's not a lot of people in a space There's probably not going to be as much co2 and so it's it's it's a way you can't do like You know, COVID testing and the air are quite yet Um, but you could do this Yeah, it's pretty cool. All right. Thanks so much Kevin. Thank you Kevin You guys have a good night. Thank you. See you stay safe. All right next up Let's go to Dylan and then after Dylan will go to Melissa Dylan. Hello, Dylan. Take it away. How you doing? Hey, I'm doing well I have a few things or two things to show Yeah, first, um This which is the little thing I made. Um, or I didn't make it. I designed it. Um but You can it essentially lets you put A keyboard on top of your. Oh, that's a good idea. That's a good idea. Um, well, okay It's not my idea. I stole it from like some Japanese company, but like good stealing. I used to know that Um, I also made one in aluminum because I kind of feel like it like kind of Looks a bit better. Good artist borrow great artist steal and share on show until nice um, and then we also have um, these I made some coiled cables with the like yca connectors that were um Recently stocked in the Adafruit shop Um, a blowtorch may or may not have been involved and I may or not may not have been blowtorching. Um A heat shrink thing of a AAA batteries, right, but um, yeah Yeah um Yeah, so oh well your fingers will grow back If you're like under 25, it's yeah I'm like, I mean, I have a carbon monoxide detector now. So like air quality is the theme Apparently your qualities solves all problems All right. All right. Looks great. You got all sorts of key projects going on. Nice work. Thanks. Thanks so much Dylan All right. Next up. Let's go to melissa. Hey melissa and Melissa Yes, uh, so I've been working on this code editor. I um Took one that scott had actually done and it didn't really have much of the way of style to it and I've been applying this new one and so I have a That's good. Um a clue connected right now So I'm just going to hit connect because I previously appeared it And then I'm going to hit bond and so that'll go ahead and load this and it'll load all the code that's on it currently And then we can also go to the serial to see there And I have it so like you can go ahead and resize it to all sorts of uh, that's nice. This looks great Is there anything browsers can't do? Uh currently I was working on the buttons up here and they're not currently Functional so I'm going to probably just uh Comment those out, but it'll work as it currently was working Which was it would just kind of save the file as you edited it All right. Well looking forward to uh trying this soon Nice work. Thanks. Thanks so much. Melissa. All right. We're going to go to john park next jp How are you doing? Hey, I'm doing well. Thanks. Uh, so I just put out a guide on this little guy It's uh called the deluxe four by four neopixel keypad and it uses this really nice aluminum Keypad case that we have I've got a qt pi m zero in there running some arduino code And this is uh keeping a tempo of 120 beats per minute right now that'll send out little midi clock signals to things And then I'm just using it to run a software synth But the nice thing is you can put like a couple of octaves of a particular key that sounds good. So I like that's really clicky it kind of goes with like the The vibraphone it is. Yeah, you're right Little percussive element to it. So yeah, uh, so that guide is out and uh, you can grab that you can do anything You want with it. Of course, it could be uh usb hid stuff usb midi stuff Non usb things you could make some little tic tac toe games on there with the leds, I suppose if you want but it is uh It is a good project for people who want to grab our ortho snap apart keypad and then Place it into a nice case and hook up a little qt pi to it. I like how you made it really easy It's just like you just snap into four by four and because everyone uses the same spacing about 0.75 inches It's like just fits It just fits and uh, I was really impressed because there was something you had said at one point that you had done And with the design which is when you snap off a whole column the Neopixel line and uh continues to yeah No, it does exactly as long as it's it's rectangular or square that you don't have to jump or anything It'll actually do the right thing by by weakly passing the neopixel signal down Um, you can sort of see the design. It was a little bit of a a little bit of a hack, but I thought it was um It kind of does the thing that you want it to do I don't think you realize how That isn't what most Um ortho pads do like usually you do have to do some jump ring But I really wanted I wanted to do it so it's like you can have the minimum number of wires possible Very easy. Yeah, we're great. In fact, I have it open open in the back So you can kind of see the the the wires so Whoa, so the only wiring I have is Rose columns rows are in blue columns are in yellow. There's a green line there Which is my one neopixel line and the rest of it's all PCB and then power and ground. Yeah. Yeah Yeah, I hope people, uh, you know pick these up and and use them to make um pads I'm also going to do you know a version that maybe that already has like a footprint for like a you know a keyboard um Break out, but you know, I'm going to revisit this design this design took so long It was so tedious because you know what any change I made I had to change 30 times Yeah, this design took way longer than I wanted All right. Good work. We're gonna be playing some of the videos that you did during the week on ask an engineer tonight And this also, uh, kind of looks like a night writer prop to like oh, yeah Yeah, man, that was fun to do the little larson scan Yeah, and you can have the musical stylings of David Hasselhoff, okay This website's free everybody All right, thanks so jerry All right next uh Name Pedro. Hello Hey guys. Hello everybody. Here's what we have this week. All right. So this week, uh Still ramping up through the halloween prop project So this was a request from phil you'd really like suicide squad and our task was to build the rat catcher's wand or Communication device and the hard part about this was it I think it was in like three scenes in the entire movie So I had like literally three shots to get of it and most of them she's always covering it up or it's like completely There's like rats. Yeah, there's rats or there's like dirt all over. I think it looks really great That looks exactly, you know, sometimes it's like making a prop look like the movie. It's You know part. I mean again, their thing doesn't work either. It's not real You know, it's a prop also So as long as you can get it to the point where it's recognizable. I mean when I saw it I was like, oh, yeah, this is it Yeah, I really like how they had like the jst wires all hanging out So it was like, oh cool. I get to incorporate that and I don't have to hide it, but yeah, it's all Yeah, they probably built it the same way you did. I mean like Just for yeah, just so for folks know and then also Disclosure by the way, we have nothing to do with dc or marvel or suicide squad or anything We have the movies we happen to like the movies once and all But we saw our stuff in the suicide squad. They used one of our boards And we had a little segment on that before but then when we saw this we're like, oh, this is a really cool project To show people that if they see something in a movie Not only could they make that But um, you know, there's entire careers now just making things for cinema and a lot of these Media places use our stuff. So this was a combination of all that. Yeah, what anyways, we never we don't get paid to do this We had to pay to watch the movie Yeah, I wouldn't be surprised if they used a bunch of the same components Which is literally just a circuit playground express and the 2200 uh, cylindrical battery I like the simplicity of this I'd like I like no solder prop projects, you know, I mean like That's it's I know that it's you know, that's not there there's more elegant ways to build this but I I do like um I do like it and I think you know, it's funny that you The the ball and the circuit playground express fits perfectly in it And I also like that it only shines out the end. I actually kind of like that a little bit Yeah, I kept looking at the scenes thinking. Oh, do I have to put like a ring on the back? But in the end it's like, oh no just use like a the filament that'll diffuse it Yeah, I like it just it seems very directional. I think it's I think it's cool Yeah, so we talked about all the CAD on our 3d hangouts and then you can get all the fusion 360 files Or just the stl if you just want to print it out and a nice little simple assembly You can check out the learn guide for that. All right, great work And we played some of these videos and more on Ask an engineer tonight. That's right. Thanks guys. All right All right, we're gonna go to liz and then we're gonna go to mark liz. How you doing? Good. How are you? Good. What you got going on? Uh, so a couple weeks ago, um, I had bread boarded up a fuzz guitar pedal circuit And I finally did a pcb layout for it Um, so I sent this off to ash park. So hopefully I've been like a week or two Um, but it was cool. I feel like I got to Understand the circuit a little bit more like doing the layout and the schematic and everything. Um, and then on the silk screen I got this, um, like tv white noise Of as a design so that'll be on the back along with the name Kirby I like the kind of like it's curvy But it's like there's curves that don't make any sense and I'm kind of digging that Thank you. Yeah, I I love curvy traces. I don't know why but um Uh, and I tried to keep it really small too like the resistors are actually made so that they'll be standing up for placement um, and Yeah, and I won't like solder the pots like directly to the board like all wires coming out same for the It'll be nice and small. Um, so yeah, it's some of those working on Looks good. All right. Well, good work. Keep at it and keep coming back We'll do once it's also come back. Yeah, once you get the pcb to come on back bring your purple purple tv All right. See later. Liz. Good. Thank you, Liz All right mark place out what you got going on this week. Hey mark. That's good Uh, I finally had time to play around with whippersnapper During ask an engineer a couple weeks ago. I actually quickly set it up And I thought I just wanted to see what I could do with it. So I'm going to adjust my camera down to where My fun house is sitting. Sorry um, so right now it's not doing anything but I'll share my screen and There it goes Um And just to show the power that I found and even the minimal functionality in here right now No code and when I say I had a little time to play with it this took about half an hour Now through a different i o I can start controlling the leds. You can't really see the green one. Yeah. Yeah, we can see him and the blue one and the red one And well, this is cool if you want to turn leds on and off which is always fun um The triggers in a to fruit i o already there Is just amazing. So I've got a lot here all these led tests are all what you're seeing in front right now Uh, but speaking of air quality, uh, you can take advantage of your existing feed So I've got a couple triggers set up that is outside monitoring the air quality right now We've had a lot of smoke fire our fire smoke from the fires around us Yeah, and it's easy to set it if it's greater than 50 then set right now. This is just the onboard led To turn on using multiple leds. So you can have a little warning system is the air good green Uh, I don't actually have a yellow led I found yesterday. Uh, so it's blue Uh and red for bad, but this is all off existing feeds that I had already So I didn't have to Do anything more I could immediately build a little display for indoors And as I said, it took about half an hour of time Yeah, I like that I like mqtt and you know one of the things about it if I know that That we did was like it uses an existing standard mqtt and all these feeds That's subscribed and published to each other and so you can take advantage of the fact that you already have this like published subscribe um set up to Have data come in and move around and do webhooks And it's like it's just raw data. I want to say a little bit of like, you know You know like neil stevensons article, you know is early paper about unix It's like if everything's a text file and you can manipulate everything is text files You can have all these little tools in unix where you can pipe data and move it and filter it and have things Connect to other things and so we're that kind of philosophies, you know What we're trying to do with io where you you have these data feeds that are just really kind of plain text And then you can really easily adapt and move them around because they're they aren't Um, they're like bubbles of data. They're just like raw data like the number is the number It isn't like a number that's encoded in base 64 and a thing that's in an envelope. That's pgp signed It's like no it's a number Yeah, and that's exactly what I found. I didn't I hadn't never played with the triggers before And then all of a sudden I was like wait I can take this existing feed and then feed it into this other service that I've just used and It can trigger something else and yeah It It was so simple. I mean it was too easy Yeah, no way We're definitely going to get the feedback that we make we're make we're making uh air quality sensors and iot Too easy. It's kind of a yeah, that's fine. Um But I think that one of the things too is when people think about the things they want to do And they say it in regular human language io kind of helps you along with that like if this thing Is 50 then light up this led Green And it's like a very it's like oh, I understand what that's doing I understand what that is and I and I there's something in my home That's going to light up after the air quality gets to a certain number It seems to make sense for I think a lot of people Yeah, that's what I found as a intro project is something that's new this works great and it's just And it took almost no time to figure it out and yeah for anyone learning It's a perfect system for beginners. I can get started then for experts are like I do not I'm an expert I don't always my remaining years left because it takes took me so long to become an expert So I want that I want stuff to be easy now Well, it's nice. I've got a bunch of things using it a fruit io today. So now if I want to hook up a Display just indoors to show me. It's not like I have to be like, okay Find this find this and just write the same code you've written in 10 000 times before Yeah, that you can't find anymore because who knows where you saved it. Yeah, so I'll keep giving good beta feedback. Thanks for testing it out and showing this off It's all very new and you know, we're in beta and so anything that you find will help us and we're going to You know, we're going to create the same kind of system We have for circuit python where it's it's there's releases and updates and hopefully people can also contribute So if you have a sensor that we isn't supported you'll be able to contribute the code to it We can you know, I mean there's thousands of different sensors and and we'll slowly get there Um, but we're hoping that the community, you know by having an open standard and having all this code be available Hopefully you can get uh people to contribute the code that they need to finish their projects to work together Yeah, I'm really looking forward to seeing when that's out there All right. Well, thanks mark. Sorry. We made it so easy. Um, I could send you some crummy websites Uh, later if you get frustrated about or something. I have a list I could send it sounds great Thanks a lot. Bye. Thanks everybody. All right. That's that's a wrap. We have uh, you know, sometimes it's short and sweet Sometimes we go over super 10 minutes. We're going to be on uh back with ask engineer at eight o'clock. So stay tuned Yeah, and for longtime viewers We'll probably have a guest on show until next week. So we'll uh, we'll talk about that next week So we'll see you all later ask an engineer starts in about 10 minutes. Thanks everybody. Bye. Bye
