 All right, lady. What is this everybody and welcome to show and tell it's us Lady eight and mr. Lady data back in the factory. This is not a green screen back drop This is the eight of the factory where we manufacture all the electronic goodies that you know and love And we're we're getting back into our groove doing a broadcast from downtown Manhattan lives we're doing show and tell right now the next half an hour and post this will be JP and his magical box of unboxing eight of box. That's a lot of boxing, but yeah That's gonna be at 8 p.m. So let's kick it off. We've got a bunch of folks starting with Kevin from digickey who is outside. Yes, and he's aware. He's outside It's on purpose. How you doing? Yes, I am aware. I'm outside and this is what northern Minnesota looks like in a summer It's 80 degrees though For three days enjoy it is it's gorgeous out here. So I'm outside because most people at digickey now have their second vaccination and my wife and some of her teams also work with digickey and it department They decided to have a get-together after what it's been 15 months. You can do it now They are getting together so I didn't think this through because I was gonna show my phone because I can actually monitor the Temperature of my house from my phone, but I'm using my phone for stream yard. So this just I didn't think it through, but that's okay. I love this little guy. I have a monitor in the temperature The pressure the air pressure air pressure and the humidity. You probably can't see because it's so bright Oh, yeah humidity pressure. Okay. Yeah, and I'm monitoring it with a different IO as well so you can I Can get charts and graphs and you know it's I'm sure what what is it doing throughout the day? And I could I haven't done it yet, but I could set up alerts to alert me on my phone if I wanted to So I I keep the more I play with this fun house the more I like it and I This is my problem. I did not realize that this vine on the one side was a Slider it is. Yeah, it's a secret though. Yeah Oh, it's not a secret anymore. Well, it's really a secret. Well, yeah It was very secretive to me because I've been playing with these things for a while and I ran across that today and I'm pretty excited So that's the cool thing about electronics, especially the ones that we make there's all sorts of things even when you think you've learned everything about it You're done. There's still more to discover. Yeah, exactly So you can you can do both and the slider is there it's not an awesome slider It's like only five boxes. We can use it for like brightening or dimming things. That was the idea. Yeah. Yeah, exactly I noticed that it's like a 20% through whatever for each step Yeah, it's great. Okay. Well, thank you so much Kevin. I'm hoping I can go home tonight I was telling Phil before the show that I got kicked out of my house and It was awesome. I was about to say, well, you can move to New York for a while and you can hang out here as well We'll make it we'll make it work out. No, no quarantine. Stay on the couch. Yeah, all is good. I mean, it's good to get out It's good for people to start getting together where it, you know, where they're vaccinated and where it works out So it's great to see you guys in the factory and maybe next week Maybe I should do something from the new Ditchkey warehouse. Absolutely. That'd be great And please send all regards everyone in your group and everyone a digit key You know, I feel like this is the next this today is the first time we've seen each other without a mass in different locations in our Homes because we were broadcasting from home and then with the factory we have mass on so it didn't make sense to do from here So thank you did you key and everyone for keeping each other company all throughout the last year Yeah, and thank you guys looking forward to JP show afterwards on the eight a box Which did you use the sponsor of? speaking of oh Yeah, so did you key is sponsoring the hackaday prize? Yes, we are and that kicked off today. That's right non-stop Yeah, so definitely go to check out the hackaday prize and see if people on show and tell have have what it takes to Be the next winners. Okay. Yeah, all right. Thank you so much Kevin. Thanks. Take care guys. Bye All right next up special guest. We worked this one out in advance Armstrong Hi, hi everyone. All right. So armstrong you happen to be and let me see what happens if I get this Graphic up you happen to be an author of a book that we just bought Let's see what happens here No, it did not show let me show let me try this again. I think you have to do Yeah, anyways, so that's picture of the book Yeah Yeah, so my book is basically on programming microcontrollers using a circuit Python You know, you try to incorporate everything You know get a crash course on Python crash course in electronics Um, you can use basically any board that supports circuit Python So, you know, I need a fruit has a lot of a lot of awesome boards that you could you know fall along with the book So, you know, it won't give you a block belt and circuit Python But you'll probably get a yellow belt after completing the book you'll be able to you know Probably do all you awesome tutorials you'd offer provides and you know all projects on the web and stuff So that's really the just stuff of what the book is about. Yeah. All right And so in the Adafruit daily newsletter, we added a link to your book We posted up on our website and I'm gonna be sending over some questions So I'm strong about what it's like to write this book some of the things that you can learn And so expect to see that interview on our website and then also We'll probably put it on Newsletter and then Armstrong maybe come back Whenever you want we're here every week Wednesday and show maybe a project from the books if folks know what they could build Yeah, yeah, that'd be really awesome. That'd be great. Okay. Cool. All right right on Person now and congrats on getting a book out and where can they get the book? You can get a book on Amazon on a from it a press direct You can get it from us bring up, you know the distribution channels Okay, cool. Someone can post some links up in the chats to purchase the book Please do because we're gonna keep doing this show tell All right, we're gonna keep moving along we have some of our team members here I'm gonna start with Trevor this week What's up, you got going on this week? I got a few things going on so I have two things to show up if you guys don't mind Yeah, all right, cool. So the first thing I'll show off Will be let's see this first So we added some new stickers to our stickers app. Can you see that? Here we go? So we have I think we yeah, we added nine new stickers so stickers that We added the the trinkets the four of them We added some blink of stickers as well, and we also added the bundle fly. That's always good to add. Oh, yeah This is a new key, right? Yeah, there's a whole crew Yeah, and yeah, they're pretty pretty cool. That's available now on the app store. Absolutely. Yep, and it's free Is that Let's see let me just share the screen so Can you see that there we go? All right, so we have this going this is the Glider app that Scott came up with So it's a follow transfer app and right here. You'll see like we're writing towards the nrf2 boards I think this might be the the second playground blue fruit and we're able to we're able to read it or I'm sorry, right? It was a right and and also read what we got back from the from the board itself So right now it's still in its development stage, but it's coming along really well All right, right tomorrow. I'll be posting up a video Because we're we're beta testers on this app and I filmed more using it from a phone to a clue board So we'll have that demo as well This is really neat for all the folks who like circuit Python how easy it is with like it just shows up as a Drive imagine that but for mobile devices and for getting stuff back and forth and then maybe even coding. Oh, okay All right, all right next up speaking up. Hey, Scott Hello, what you got going on first? I want to say shout out to Antonio for doing that second video He was the one that put the file transfer app together So what I've been working on right before I'm starting to do BLE stuff is One of the things I wanted to change for seven was how the LED flashes is particularly when errors happen So here's an old clue here that I've got and it I was actually working on something else And I had it flashing this error So this is what it does currently and you'll notice that though the LEDs on a lot And that means that it takes a lot of power. So I've actually in seven. It's going to be much quieter The the QT pie here. I have it only blinks every five seconds And that's so that it can do a light sleep in that five seconds. So if you have a battery-powered project and For some reason the code stopped running it will blink every five seconds to read for an error green once if it's a If the code finished successfully and then if it's in safe mode, it'll be three yellow blinks So it'd be a lot simpler and the idea is that the the LED will only blink when it wants your attention now And saving a lot of power Yeah, and thanks for thanks to folks in the deep dive chat who pointed out that it's like attention seeking at this point and Also, the cat is Behind me. He doesn't like you or she but always is around you. Yeah, that's spook. He he's always in here He's always on cat cam for my deep dives on Friday at 2 p.m. Pacific I was gonna say one is your next deep Yeah, and the big 5 p.m. He's true of front Yeah, 5 p.m. Eastern on Friday. We'll be talking about Bailey workflow stuff this week and Did just get a question about the colorblind colors So all of all of the blinks also do different counts of blinks. Um, so it's not actually dependent on the color at all So if a board does not have an RGB LED, it will just do this thing It will do the same number of blinks on the single LED on the board All right, good stuff All right, thank you so much. Thank you. Thank you Scott Brent hello, Brent. Hello, what you got? I have a I have a live demo. Hopefully this will work So I was looking at this awesome like demo we have on the Adafruit shop of the breadboard with waving your hand over the PIR sensor and the LED lights up and I have a fun house with the PIR sensor attached to it and I've been playing around with Adafruit whippersnapper and I was trying to think of What would be a really interesting project that's doable really quickly and We added a fun house to whippersnapper last Friday, which is really great We have a video up on the blog and showing how we add a PIR sensor Which is really quick. You just click new component and then click PIR sensor and even like circles around and If I wave my hand over it it'll show that's closed or it's open So if you want to add an email notification, we would hit new trigger Reactive trigger and then we can select the PIR sensor. Oh scrolled right past it Oh man Yeah, it should have been there So you would select the PIR sensor and then when it's on it's digital high So that's one and we would choose when it's greater than zero and then we would say email me and PIR We create so whenever I weave my hand over it and I'll go back to the whippersnapper view Says it's closed and since it's an Adafruit IO feed We can see how much I've been waving my hand over it a lot Um a lot and then if I go back to my inbox and I hit refresh I have an email from Adafruit IO saying that there's a new value of the sensor. So It's a really quick way. Yeah, I was like this virtually well I actually made the LED demo and then I was like that's not an IOT demo So I made this demo instead. The only bad thing about the demo is it doesn't seem real because IOT projects are supposed to take forever You should be signing up with your credit card and like to be down That was way too easy nope and then converting something from ASCII to like you you hacks. Yeah And then you need the JWT. Yeah, no Adafruit IO is free whippersnapper will also be free for up to a number of devices and Great, not out yet, but it will be soon. Okay. Thank you so much for a great preview. Thank you, Brent Thanks up. No Pedro what you get going on this week? Hey folks this week We have two things for the fun house So this week we kind of have a fun house video and last week we had a learn guide for the little stands There's a little three-printed stand it has like this brick texture and then this week I have this this little light switch plate so it fits you like you're kind of standard light switches here in the states I think it's standardized. Maybe it's not but you can modify this design It's just prints in an hour or so and then for the demo. It's running circuit python So this is a slightly modified version of JP's door alarm So I got my little dashboard here. So it'll notify me when When the door is open Yes, so it's connected to the magnetic switch It's open that's bad because we're gonna install this onto a baby gate. So the baby gets out red. So if we close the gate Okay, get back in there, baby. I also get an email too. Oh, we should probably get an email Yes, yeah Red danger so I really easy to set this up And we just added some nice bitmaps to kind of make the screen look nice All right The learn guides up right now and you can grab the files Yeah, I'm 30 how you can use my caster. That's like built in into fusion 316 You can get like a custom faceplate design like depending on whatever design your house has So great for parts orages if you can't find your switch plate that parts orages. Yes Once of that Thanks, guys Liz how are you doing Liz? He's got fumes got a lot of fumes So working on a project with the fun house where it's a basically a smart solder fume extractor So I'm also live and demo time because sometimes you don't want to send your fumes to the internet I thought this is a price of your coin today. Ah The crypto bros Yes So we got a little menu here. So yes I want to send fumes to and then while it's connecting you get a little connection screen and Then we have our data and there's two feeds on there right now. I have a window open So there's a lot of airflow, but if I cover it it might go up a little bit and If you decided like halfway through like you didn't want to be sending your fumes you can press the top button here and Should go you had fumes updates. Yes There you have a general purpose like air quality inventing like it's a good It's a good mini demo like some people might be like well a fume extractor doesn't make sense But it's like what if this was actually more like a home or a Factory and there's there's fumes that you want to vent outside You have a laser cutter a lot people have laser cutters and they forget to turn on the fume extractor this would do that for you Yes, yes. Yeah, because I actually did them with the map value Function I have the PWM of the fan connected to the amount of CO2. So they're directly related Cool. Yeah. All right. Good work. Thank you so much. Thanks. Good fan. I'm a fan of your fan next Except Alvaro. How are you doing? Hello? So how about a couple of things to show today? Yeah One of them is the this pipe portal. So if you can share the screen, please Yeah, I will share the screen. I see us. There you go. Okay. It looks like you got a website Yeah, what I have is something to check on the API of web leads to know how many Translation are missing in secret Python. So when Scott do does another Another marriage or whatever. So this thing will tell me here and I can go and and fix it, right? so That's one of the percent. Yay. We did it. Yep. So another another of the project is this tiny Yeah Chichi girl Yeah, because it's kind of hard to see the screen. I have some screenshots in the in the screen So if you want to check it out. Yeah, so this thing is actually a lot of T to go so it has a new speed 32 and a lot of chip So what it's doing right now is that you can you can see here that this is the satellite actually going on top of Here in Costa Rica So if you actually plug one of these boards that cost, you know, like 30 bucks or 40 bucks You can actually get messages from from satellites and the cool thing about that is that When you get the message from the satellites, you actually get all of these telemetry here you can see You can see for example all the the satellites and The real the data and real time that they're sending so how much transmit power do they have was the temperature? If they have son or not right now, etc. So It's really really cool and it actually worked with these tiny antennas So if anybody wants to to build it again, it's really cheap to build it And if you want to listen to to even more satellites, it's Actually, yeah, it's a good project to actually learn how to build antennas. So nice All right, let's set up in the discord chat. Sure people would love to build it All right next up magenta. Hello, how's it going? You're muted. So I'm mute and I think you're gonna talk about An event right Yeah, telling you all about the hackaday prize, it's the eighth year of the hackaday prize and we just launched Yesterday, so thank you so much for having me on to tell everyone a little bit more about it For those who are unfamiliar I can just launch into sort of the spiel or if you guys want to ask me questions about it I have your one minute video so do an overview and then I'll play the video that you're also in so it's kind of like you Yeah Inception hackaday prize moment. Well, thank you so much. Yeah So the hackaday prize this year. We're returning to sort of the style We did a couple years ago in 2018 where we have our monthly challenges. So the the entire contest is open until November but the monthly challenges are open for Three to five weeks at a time depending on the challenge the first one which launched the same day as launch day or opened up the entry period is the Rethink displays and so we're asking people to reinvent sort of different display technologies and use them as new ways to communicate visually, you know, so much of communication has Had to adapt to our current times over the last year and a half And so we're looking for innovations that have to do with that And the top 10 finalists of each monthly challenge will get $500 to move on and we'll be announcing those Shortly after the close of each entry period. They'll get $500 to keep pushing their project to the final round Where they can be eligible basically up? Up for judging to receive any of the top five prizes. So our grand prize is $25,000 and a residency Oh, I see Helen in the comments. Hi everyone in the comments Residency at supply frame design lab. So this year. We're currently working with last year's hackaday prize winner at design lab the bite And then second place is 15,000 third place is 10,000 fourth place is $5,000 and fifth place is $3,000. So those are the prizes There's more info at prize.supplyframe.com or on hackaday.io on the 2021 Hackaday prize contest page. Okay, and I'm gonna show this one-minute video if that's okay. Yeah, perfect. Thank you Okay, so let's see if this feature works with Welcome back everyone. My name is Magenta and I'm thrilled to be announcing the 2021 supply frame design lab hackaday prize This is our chance to reset the clock reframe the challenge to hack the future Rethink the way we communicate through technology design solutions for remote collaboration create hardware that solves problems and invites the next generation of engineers build electronic companions or robots for everything from support to functional assistance or chase the wild part of pursue your own idea Reimagine refresh rebuild. This is the hackaday prize brought to you by supply frame and did you key electronics? Be sure to stay tuned for updates. There's so many ways to engage both online and in-person So gather your team nominate your mentors and get hacking All right, we have two more folks we're gonna get to let's go to Stuart and then we'll go to Lolli and then I think we are Tonight, so Stuart take it away. Hey Stuart. Hey you guys. Yeah, okay I love your stuff. I'm excited to see the way you're doing. I Have to go real quick This was like a precursor to one of my other projects, but what it is. It's a little I use it as a little trainer And a Arduino and Neopixel and display and motor. I use this with the robotics kids to show him the correlation between black programming and Incorporating the ladder knees together What I learned from the rule has brothers on Converting 3d CAD drawings into art. Oh, it looks so cool So I laser print it. I will not leave my laser etched it. Yeah onto acrylic and it came out like this I sent it to the rules brothers so they could check it out. You know, it's funny is like Before you posted I swear it was coincidence. We were looking at they were talking about like, oh We made these cool diagrams and they're like, what can we do them? I'm like, you know, that would look really great as an edge lit lamp I swear and then like an hour later. They're like somebody just sent this to us. I'm like, you got to do it now So they're gonna do a project where they make an edge lit lamp and like the board is the lamp Itself, but it looks great. I mean like great minds think alike. I don't know But looks cool. You should enter the hackaday prize by the way, you always have like great builds and stuff Thanks, don't think about it. All right. All right. Thank you so much. Sure. All right. All right Show us what you got going Can you guys hear me? Yeah, congrats on being back at the factory. It's awesome Yeah, you've been you've been with us over the last like 14 months or so So you've you've seen us from home mass on site, but now And no mass now we're post-vaccination. It's awesome. I've been fully as well. So I've been getting back I love playing cricket on the weekend. So Last year didn't play at all obviously because we just didn't want to hang around people But I'm back playing and it's good to be back on a field like running around and stuff like that But anyway, I've built this scoreboard I've been doing this for many many years like trying to get a scoreboard going that works for cricket That's when you you score on the in the cricket. I don't know This is when you slam down on the cricket. That's right So I actually got a couple of these 32 by 64 matrices and I chain them together There's a very good tutorial on the learn system on how to connect these or chain them together So on the backside, I have a matrix portal Sorry, yeah, a matrix portal that's doing the connectivity So this thing is actually pulling a website where the league actually in real time people have to score now using a phone when the score is happening on the cricket match, so I'm just pulling the score off of the site and You know putting it on the on on the display Yeah, it's it's awesome. It is so easy as always you guys code is great and you know Just files in general out there to like build this kind of things I 3d printed a couple of connectors so I can connect the two pieces together and be steady and I'm using one of these anchor 28 6 to 2600 mah capacity batteries This thing draws about two amps these USB ports here provide about two amp So it's just about right in terms of current usage for this display So it's working great I have to build out a little you know frame for this so that it sits on the ground and Possibly waterproof it because obviously it rains, you know sometimes so you can't get this wet But other than that it works pretty good. So I'll come back and show off my enclosure once I have that if You can have like a video of people playing cricket and there being a score and then like panning over to show Yes, that would be good Because one of the things I like to do is show people like here's a real thing that you can build and like you said We make it so easy that you don't you're not so exhausted from your electronics project. You can still go play cricket Yeah We're done by one you're like I can still do Too easy, but that's too bad. Sorry everyone who thinks it's too easy to do these projects But this has never been too easy until maybe now. Yeah, I don't know why people say that is ridiculous They want to be like is there oh is there like goalies and cricket they want to keep that they want a gate keep I want to keep the ball out of the goal You know, it's funny you say that my goal is to have a little camera on top of this We just flip a switch and maybe you have like a LTE Phono something that's just streaming the the camera in real time to a portal Score and the fly fee. Yeah, all in like just flip it and you go, you know, that's that's my goal That's what I'm trying to get to so We're gonna get there and you'll probably do a circuit python. It'll probably be way too easy and you'll have more time Bye-bye, we're gonna go that's our show until live unboxing. Well, sorry, they'll be recording back in the live unboxing with JP Yeah We'll be here next week some 30 p.m. Eastern time for show until 8 p.m. Asking engineer and then we'll still be posting all of our new product videos. I and MPI Python on hardware and top secret tomorrow Friday Same bedtime same bad channel. We'll see everybody next week. Thanks for joining us. That was show until
