 Live from New York. It's ask an engineer. Hey everybody and welcome to ask an engineer. It's me. Lady Ada the engineer And we're broadcasting live from our downtown Manhattan factory me lady Ada with me. Mr. Lady Ada Phil We're married people have been asking us now, you know and this is our factory It's where we manufacture all the electronics and do the videos and write the code and the tutorials All the projects that you know and love from Ada fruit, but for the next hour We're going to take you on a whirlwind tour of all the latest news and updates in the world of making hacking electrical engineering and more Mr. Lady Ada, why don't you kick it off and tell people what's on tonight's show including the code? All right on tonight's show the code is star. Oh, we'll show why soon But they get you 10% off the native food store all the way up to probably midnight Or if I remember to turn off soon on that so use it or lose it Tonight only talk about our Adafruit live shows including show and tell Time travel around in the world of makers hackers artists and engineers help wanted Jobs from jobs at Adafruit comm don't forget can also post your skills Or if you're looking for talent post up your job there. We moderate them and we make sure there's nothing weird going on Well, good weird. Anyways, it's always weird. Yeah, I mean New York City factory footage 3d printing Ion MPI New products top secret we answer your questions We do that over on discord adafruit.it slash discord where you can join all 30,000 of us join the community all that and more on you Guest it. Yes. All right. Well first up. Let's Do the usual I always have a little bit of a COVID update here because yeah New York City New York City tends to be the center of the world for a lot of stuff So New York has almost the strictest things that are being implemented as of Today, which is you need to show a proof of vaccination And ID sometimes sometimes but a proof of vaccination form app Card in some way in a lot of places basically anywhere. There's people Enter dining entertainment gyms. Yeah, if a store has seating for people Yeah, so that's starting. Yeah enforcement starts around September 12th. I think yeah next month and so our Mission has been to get any of our employees vaccinated. You still Haven't done that yet get out all the information and then be ready for the inevitable which is probably Mandates for all forms of business. So right now, it's it's And if you're not essential, yeah, well if you talk to the restaurant owners or like this is Being unfairly put on them because they're becoming the enforcers of this. Yeah, and they're not wrong. They're not wrong Yeah, so that's what's going on here. So this might be a preview of what's going on everywhere I'll San Francisco is doing fully vaccinated and it does matter on the date in New York They're saying look just anything. They just want one dose anything. It could have been yesterday They just want that vaccination rate and we actually I said to you notes from the city meeting So we've gotten just 77% of adults 18 plus. Yeah, have at least one vaccine dose Yeah, so anyways more is on the small business council of New York where Once on all you get invited to a meeting to listen to see what they're doing That gives us a little bit of a get a heads up we get a little bit of a heads up so we can plan accordingly and ate a fruit and Like I said, I think last week the trend that we're seeing and our little microcosm of the world our little slice is if people Live in households where everyone else is unvaccinated even if they are vaccinated That's when we're we've seen breakthrough cases. They've been okay, but that's what seems to be happening the the Areas where people are unvaccinated is where things are coming through so Use that information the best you can. We're just reporting it From the ground we have no say in this I'm on a council, but it's not like a council where I where they ask me questions They're like, here's what we're doing. I'm positive. No one's gonna listen to us. Yes, a bit a lot of things. Okay, so Not only do we have the code Staro, but we do freebies as you check out Lady Aida Yeah, what are the freebies? Okay, $99 and more you get a free half-size from proto It's great for taking your breadboard projects and make them permanent one 49 or more You get a free stem a qt breakout board. It could be a driver. It could be a sensor. It could be a Solometer it could be a DAC whatever got all sorts of different boards make it a count and you'll get a different one each time One night I know where you get free UPS ground shipping in the content your night continental United States If it's connected to the main 48 states You can get free UPS ground shipping and it's tracked and it's insured 299 or more you get a free circuit playground express our same d21 based board that is wonderful for Beginners or experts because it has all the stuff built in and you can code it with Arduino circuit Python code org CS discovery make code rust tiny go lisp, etc. It's a very well-supported chip I think even like Zephyr supports it. Yeah, my mute all these good things When you order for me for it. Okay, we have a live series of shows Thank you for hosting. Thank you Do the recap I think there was a bunch of cool stuff to definitely check it out Super fun. We'll be back. We we are alternating our hosting alternate mostly because It's just getting extremely busy But from what I understand I'll have to check because I watch the show until after ask an engineer Kevin was on and Kevin's from Digikey and there is a Halloween hackfest going on. We're part of it We said we'd help get the word out Halloween starts in August Halloween is all year around now And it really heats up in August. Yeah, it's really all year. No now It's just that that's what we've done as a company for the last decade plus So anyhow on Sundays we do just of Lady Eda and this week part one. What did you show? Okay, so We actually I showed off, you know, cuz I didn't have any hardware that I've been I've been working on the last week Because we've been dealing with all the stuff, but I did talk about the Adafruit design philosophy You know, what what makes an Adafruit board look like an Adafruit board because as we show there's an Adafruit board that appeared in a movie We're gonna talk about this in the show. Yeah, no spoilers no spoilers But you know it as we you know, Phil and I were watching it at home because we're married as we mentioned Um, and I saw this board flip by, you know in a hundredth of a second I was like, oh, that's an Adafruit breakup board and then I was like, wow, that's weird Why did I know that was a breakup board even though it was on screen for for like a milliseconds and The answer is there's a couple of design things that we do with color and header and mounting holes Some of this from K-town some of it from me Some of it from other people who've designed boards at Adafruit And so I just kind of talked about that stuff stuff to look for what what we do and why we do it that way and Yeah, and then we do the great search the great search is when Lady Eda uses her powers of engineering to help people find things on digikey Because there is a chip shortage. We did this show before the chip shortage, but now it's even extra handy So what what did you try to help out with this week? Okay, so you sent me? There's a crowdfunding campaign That you saw on crowd supply and they had an update we've we backed it and they had an update saying We're only waiting for one part this regulator from ti and ti is having a lot of difficulty getting parts And so I thought it was a little bit of a challenge why not attempt to find an alternative for this chip and i'm not saying that that Alternative I found is valid. There's probably a lot of reasons why it isn't but if this person the crowd funder wanted to get the board out Here's a couple alternatives that that do what they say is important and I show A couple tips I find uh using the ti website as well as the digikey website to actually purchase things like Find alternatives and actually make sure they're purchasable And we found a couple thousand of stock of an alternative part teeny bit more expensive But maybe good enough and then hopefully, you know, maybe they'll help the crowd Funder if you know other people have crowdsource projects that they're waiting on a part send them over Me and mr. Lady ada will locate to the best of our ability so far I'm able to help everybody who said they couldn't get a part Find some parts. I think the showing the process of how you find these things Is even more valuable than finding the thing because that's what you get to learn is like Oh, like that's the way to find it. So it doesn't matter what part you're looking for um, how you arrive to that So you get You don't have to slog through Decades of searching for things online like you have I I have made every mistake in in buying things And I will teach you all of the things that I've learned Uh, it's all learned the hard way All right jp's product pick we do that every single Tuesday We broadcast live from the product page here is this week's highlight from jp's product pick of the week It is the braincraft hat for machine learning on the raspberry pie Raspberry pi 4 with the braincraft hat right on top of it. I'm running the tensor flow light object recognition and it is searching for objects. I actually have the Headphone output going into a little amplifier and speakers. Let's start off with a really popular one Coffee mug excellent it did a good job with that It nailed it screwdriver, okay just for the heck of it What happens with lar's what does it think of lar's? Oh It thinks lar's is a teddy. That's very cute. Uh He's not and he's not safe. So don't use that as an example of of things you should do kids It is the braincraft hat All right jp's workshop is tomorrow and big news Congratulations jp 200 episodes That's amazing that's a lot jp has done so many shows people love them You've known jp for you know over a decade now He's always really good in front of the camera. He always bring like an infectious joy to his videos I love watching them and I learned a lot like I learned a lot from reading his guides watching his videos and checking out his projects jp is um our disney plus Uh programming and I mean that in a good way because um And I'll just tell one one story of some different possible futures So back in the day when we were casting make television and I was at make magazine Dale publisher it makes it. Hey phil, you know, you're on camera. You do stuff a lot Do you want to be the host to make television? And I said Um, I can't really look in the camera and tell kids everything is going to be okay all the time Yeah So I just I know I know that like that that little bit of sadness would always come across or I'd always think about it You definitely email. Yeah. Well, it's not email. It's just like it's like hey like sometimes things aren't going to be all right um And I feel like that's not a good look for a uh television production like you need you need people that can bury that in another place So congratulations jp I don't know. I don't know your pain. I don't know where we went, but I guess we ended up anyways Um, so that's why so we we ran into jp and that's and he's a host uh it was a host of make television Anyways, um, and you were in one of them with the uh jammer and I was a extra in one of them Yes, that's right. I get some writing for some of them, but um, anyways, good work. All right So uh this thursday, which is tomorrow, uh jp is going to be showing off this All right, and also jp does a circuit python parsec here is the latest one See you on the other side for the circuit python parsec today What I wanted to do is show how we can account for different micro controller boards Inside of one piece of code. So as you can see here, I have a whole bunch of different micro controllers They're all running the same code But the code is aware of which board it's running on and therefore can accommodate for differences where we have dot stars versus neopixels One neopixel versus many and so the way we do this is we're importing time and board and we're importing os Using os dot uname dot machine command. I'm able to set this variable called board type Which just asks the board. Hey, what type of board are you which returns a string? Then we can do things like if the word trinket was in the board name Set it up as a dot star if qt pi m zero hackspress was in the board name Set it up as a single neopixel if it's a macro pad We're gonna use the actual macro pad library to talk to the whole set of 12 neopixels This is what happens at the top of the code. We figure out which board we're using and then we set things up and port libraries Do what's necessary for that board Then inside of the main loop of the code. I'm checking a variable I created called led style So some of these actually are pretty similar once they've been set up if it's led style one It's going to use a dot star if it's style two It's going to use however many neopixels are on there if it's the style four We know it's the macro pad and we're going to use some different Code for that now. You can see this in action. I'm going to change this to be just pure green. I'm going to save that file Now you can see over here in the finder. Just copy the code one at a time So we'll go to the circle playground blue fruit. I'll hit save and now you see that blue fruit board is A a green set of neopixels if we drop that onto the macro pad Replace and you can see here. I'm not having to save eight different Code dot pi files I can use them all on any of these boards because we have accommodated for their differences This is real useful for display based boards such as the fun house and the macro pad and Pi badge pi game or anything that has a display on it. There's going to be some differences in how you set those up So that's one one use case for this And so that is how you can accommodate for different boards inside of your code dot pi Inside of circuit python and that is your circuit python parsec Okay, and next up on Fridays deep by scott next one will be this friday at 2 p.m. Pacific 5 p.m Eastern, okay great way to learn about the depths of circuit python. Yep All right time travel We're traveling to today. Well this week we're traveling to disclosureville Population us so okay, so i'm gonna have a graphic that says like disclosure Don't blame me. Yeah, not my fault. Not sponsored not part of DARPA. Yeah, don't work for Warner Brothers We have never taken DARPA money. I don't we've not no Yeah, so My disclosure is i'm gonna talk about another Warner Brothers thing it has nothing to do We we don't have anything to do with Warner Brothers. I should say We just like movies sometimes and sometimes our stuff is in the movies So Here we go that said if taco a td wanted to give me money to do something with him I would I would do it so i'd ask you for free So this is uh one of our boards and you did uh the desk of lady aida about what makes some aida fruit boards Why why does this look like an aida fruit board? So I I talked about that. So let me let me finish the disclosure So in the past no really this is where i'm at now. I know look you haven't you haven't been on twitter recently No, i mean like i don't know what's going on and i think it's been better for you So so here's the thing if Everyone wants to believe the worst in each other now. Correct. It's a problem. It's fun It's all bad faith and and I think i'm just going to spend extra time each time reassuring everyone that when you See us writing about something or if you see us talking about something It's because we want to and if we were to take money for something we would tell you so anyways our stuff was in um Disney's Mandalorian and there was a whole behind-the-scenes thing which was cool super cool So that was the the disney marvel universe now. We're in the warner brothers DC universe and we were watching suicide squad. Sorry the suicide squad and different movie not a sequel totally different and you saw Uh kink shark hold up a little thing and he's this peacemaker and uh, you noticed it was our board. Yeah one frame in And um, that's the board right there a little shark that's the board right there And now this is where it gets accusatory. So around the same time That we noticed and we started talking about this for hey cool. Look our stuff isn't a movie a movie that we liked we kind of like Harley Quinn, you know, that's cool Um for us, uh, they also had a like five second Promotional clip that was going around and it had our I had our board in it So here it is and I think this is so short. I can just play it on youtube. Yeah, I think so without youtube also being mad at me So here is six seconds. Yeah, here it is Looks nothing like me the suicide squad we did all Okay, so, um That's the board that's the look of it and you saw it in a millisecond then everyone started emailing us And I'm not the only one who apparently has yeah, and when I was watching it when I was watching the movie Um, you know, we look at this we look at everything through the lens of electronics I'm like, hey, this will be a cool thing. Let me email no one Pedro See if they'll do a 3d print of starro and put a hollowing in it. Yeah, so that's our time travels for this week I'm gonna have a little thing that goes disclosures. Don't blame me. Yeah my fault. Yeah, not corrupted Not DARPA. Cool. So Not in the big pocket of wb. Yeah Um, all right. So next time travel. This is uh, 1982 vetrex from phil b This is a vectrex one of the 8 bit 1980s game consoles and one of the very few non handheld consoles to include its own screen It had a vector crt similar to arcade games like astroys or battle zone And it dawned on me that younger viewers unless you've visited like a retro arcade You might have never seen a vector display the raster crts used for tv's and most games of the time They had an electron beam following a uniform pattern top to bottom left to right giving us that pixel grid And the world graduated to lcds and oleds, but that pixel concept remains vector displays don't have that Instead the electron beam is steered only where it's needed. So it gives this distinct look There's no pixelation, but conversely can't handle filled shapes. It's got this austere tron like aesthetic Funny thing the vectrex is a very similar size and shape to the macintosh Even has a carrying handle in the same spot the mac won awards It's in museums despite the vectrex arriving about 14 months earlier Okay, and also a little aid of box reminder So we'll be shipping next aid of box sometime in october and uh, we're already down to About only 150 openings. Uh, it'll change. They're going there. You know, we're a couple of day Are going yeah Um, so if you haven't already go to aid of box.com. All right Every monday tuesday thursday friday, we have colin's notes This week is no exception. I'm going to play One out of the last ones from the last week. Yes. Um, do you but they're all very good I think I'm gonna do knobs. I like the knob do the knobs one very informative. Let's do knobs knobs knobs use a variety of standards to fit securely on potentiometers encoders rotary switches, what have you In addition to shaft diameter, there's three basic shapes. You're most likely to see Smooth or round Uses a simple cylindrical shaft. The knob is secured by a tiny set screw on its side And yes, that screw is easy to lose and can come loose if not tightened fully Knurled or split shaft are easy to spot with their rounded teeth Be careful of subtypes which use different spacing between the teeth or splines 18t is the most common standard. So go with that if you have to choose B shaft or flatted shaft is the most simple Stabilized by the shaft's cutaway cylinder shape as long as the knobs indicator line is placed correctly relative to the pot's orientation, you're good to go All right, and I did see a question in the chat that I can hit real time Will we ever have Collin videos that are in landscape? The answer is not collins lab notes and the reason is and I know this is going to be Not great news for some folks. Most people watch content on their phones Or tablets or they're what? Yeah, well, it's not even it's not even this is a different format We have this video is is long it is and his videos are tall And I think we have a little bit for everybody it is so what even even with the landscape ones Most people are watching A video on their phones. That's the stats from all the Reports that we look at across all the video places that we use And They're they're looking at stuff and their their attention span is pretty short And so we're using this as bite-sized pieces to get knowledge out It's it's a little bit of a you know, you your creativity is pushed when you have constraints and in this case the constraint is minute or less and you know Portrait format and with a very short intro and and outro And you know what what can we teach about electronics in a minute? And I think it's actually kind of fun I think the video is like, you know, they encapsulate a very small But succinct piece of information they get right to the business. There's no like hey everybody hit that like subscribe button Welcome bros like here's what i'm doing. You're ready for lunch. No, just go straight into knobs and um The other thing is with colin's videos in particular is you're watching them, but you're there for the voice Yeah, that's what it is. Okay other bits of time travel Adafruit io, uh, this is a tweet that someone just put out. They were able to Sign in for the beta for whipper snapper and they were able to get a iot button with if then this that all integrated in less than um 15 minutes and without writing a single line of code Yep, wait till you see what we've got up our sleeves with yes We are we are doing everything. We're combining everything we've learned about. Yeah, um, no code easy deployment um People who have only chromebooks people have only mobile phones people who like You know have locked down windows 7 computers. How can we make an iot platform that works for them? Yeah, so for the people who want to join this, um, I think this is interesting if if this was a startup it would be on um Like product hun and it would be on like tech crunch and all that but we're not a startup We don't operate that way. Um, this is an iot no code solution that uh is the most open System that I know of. Um, it doesn't it's free. It's free and it it uh, we don't force you to use Um only our devices so anyways if you want to be part of the beta All you have to do is go to our discord server and post in the help with adafruit.io and say that you'd like to be um a whipper snapper beta Person and that's it. Um, and we'll probably do something special for folks around the beta But um, it is super easy no code you could do anything with you know what else we did 15 minutes or less This is the thing that like i'm so proud of We are getting rid of the whole like it shows up as an access point Then you have to get at your phone you have to change the access point Then you have to go to the thing and you have to enter it in and then you have to undo We're getting rid of that you you enter in your credentials onto uh a javascript form that is Wedding on your computer so we don't even know what your credential data is and it generates Um a hex file and then programs programs it into your esp32 using web serial So all you need is a chrome browser, which every computer can get it's free And uh all of the deployment stuff we're going to try to make it as easy as possible And don't take our word for it. You can start to see what folks are saying Um What we want to do is have something that's so easy that we get criticized for making it too easy for everyone Which we do with everything else Those are gonna be our motto so easy even a girl could do it, but you you and I decided to do something different Yeah, that's a little a different history. You wanted to have that as the the tagline That was gonna be the a different motto and I thought that would would have divided people up But instead of bring them together as I said, well, maybe we could say it once in a while But maybe we shouldn't have that like On the website. Yeah Yeah, anyways We could still do it All right, help on it Okay, um, I just wanted to recap we have some new jobs that came into the job board But I want to recap the ones are there because I think these are relevant So open hardware summit share seeking an influencer content creator rock star digikey software developer Yes, um c c plus plus python arduino and design build wearable necklace Pendant that buzzes. Cool. These are all interesting jobs that you could get now. Yes. All right. Let's do some python on hardware Okay, blinker. What's new this week? All right So two things this week, um, what I usually do i'm gonna quickly show the newsletter is a monster I'm in a good way. So we have our circuit python 7 alpha 6 release. Do check it out. You can look at all the Editions since 7.0 Sign up check that out already talked about the halloween hackfest Um, tom's hardware reviewed the macro pad and gave it outstanding. It's a tom. It's editor's choice Oh, um, and so it's the ultimate diy keypad. Uh, we're seeing a lot of people do cool stuff with it Thanks, tom last week. We did, um Yeah, I wonder I guess we is that tom the editor Tom's hardware. It's his hardware I should find out and see who is tom. I wonder if it's like my spacer is a guy in the background. Yeah friend. Yeah, I'm your buddy. I think anyone remembers that. Um my control of course last week we Showed it was like breaking news. Uh, it was staroids. I think that's what it's called and it's um, all the different ways You can use one code dot py file across all these different boards different screens which is unheard of in devices and electronics and so, uh, we got that going on with over four different processors So you can run same everything. Uh, you don't have to do anything different Drop the code on and it just runs across, uh, nrf 52 8 40 rp 20 40 samd 51 Um, esp 32 s 2 and I think there's no scms. Yeah Whatever whatever chips teen c4 anything that's supported by circuit python. It's consistent. It's the same All right, um, I'm going to show a video in a second and then um, we've been talking about air quality here To fruit a bunch because we have all these co2 monitors and we've been keeping From the very beginning of last year because we were in a central business. We were still, uh Back before vaccines and everything we were working we had mass on but we wanted to make sure we had the best, uh air quality and circulation and fresh air coming in Um, and so It's always good to see these projects because I think a lot of people are starting to do it It is a is a way to see how good the air is. It's a great project for kids in school It's like it's you know, it's very easy. We have a lot of really easy air quality monitor project And they're not expensive and you can learn about science and like co2 it's used for air quality But it's also used for environmental science and for greenhouse and um agricultural science with their being smoke and You name it that's going in the air and then that's the outside and then when you're inside You want to make sure the co2 levels are low because it means there's less people and Not having a bunch of people indoors right now is a good idea. Yeah, um, so anyways, uh Check that one out and all the rest of the stuff In the newsletter keyboard but this week I pick one thing each week and this week. I picked this this is Um, I'm gonna do the narration over this. This is a uh person who does mmo's and they said hey I knew this would be perfect for my mmo hockey. So this person, uh, they use a controller So it's nice and they showed all the shortcuts. So as they, um Click the buttons you can see Oh for emotes. What a great idea. Yeah, there's usually like a pane to type in and they notice that it's Easy to use with circuit my thumb and the person said I still have some adjustments to make Two colors and different shortcuts available, but I like it so far. So they were able to put this together really fast and, um You can see how, uh With the knob you can select different things for each and they said this is pretty easy for, uh, easy to have easy for me Uh, these keycaps are from an old keyboard. They're gonna get nicer ones and so this project will continue I'm so happy. I really, you know, the macro pad it kind of it's one of those things where I was a little worried because it Kind of does one thing But turns out that one thing is something that people really want. So I think it's cool that, um, You know, I I don't play fawn fancy online. It looks super fun. I definitely don't have time for that. Um And uh, I look like these are for adobe and obs and streaming and and what a handy All in one tool and I love that they decorated it with these kooky caps as well And you know and learning about more code is fun and that's how they close the video I I think that this is one of those times once again where I'm just gonna say There's gatekeepers in the world of electronics and they are terrified to see things like this because it's so easy And there's people that have never done coding that they're people like, oh, that's not really coding. You just edited an adjacent file How is that coding? It's like that's coding and and so and so this is the start and look at the tool that someone gets On like the most valuable real estate their desk And the thing that they care about and the thing that they do every day. So I think that's one of the things like we we definitely get, um Uh snarked on because we're making things too easy, but we're not making things too easy We're just making things more accessible to people Easy is subjective. So anyways, so easy. All right, and that's python on herma this week Even a stake you do it Okay, cool Next up. All right. We're an open source hardware company to prove it We have 2,525 guides. Lady at it. What's on the big board this week couple guides this week Katnie got up a guide for the Adafruit mcp 9601. It's an i-squared two thermo couple amplifier one of the very few i-squared two thermo couple amplifiers out there known on stomach qt board There's a guide jp did a project on how to make a custom numpad mechanical keyboard using our ortho snap key snap apart thingies And I think it's with a RP 2040 feather. I don't remember exactly what the mic controller is I'm just showing how to make a custom keyboard and then some really interesting tools that will do like the plate Layout and then like the definition like it there Don't go for the you know Circuit pythons stay for like all the extra tools that he shows you how to use And then we're doing more camera stuff. Jepler did this cool thing where He snagged some code that was used in open mv by somebody else that does QR decoding not creating a QR code But actually scanning them with a camera and we got working in circuit python And we're using the esp32 s2 kaluga dev kit And we even did a project where it scans a QR code and then goes to the internet and puts that data on the internet So you can really start to combine and make very complicated Demo's it's not incredibly fast for QR code, but it it does work. Um, and I think that's really neat Okay, all right next up. Let's do some factory footage and when beef factory footage without at least a photo of something going outside this is the uh freedom tower reaching up into the clouds and This is Disney headquarters across the street. So they're adding more and more floors every week. Yeah Seeing it built real time And it's happening All right 3d printing now Pedro back And that means we have two videos. We're gonna play them back to back Um before I do it though, I'm just gonna remind everybody Because one of the videos the starro of the show star. Um is uh star. Oh because we have a 3d printer star. Star. Oh So, uh, this is where we got the idea from and uh, that's the discount code for tonight Put it on your face And here is the dev videos for this week Hey, what's up folks in this project? We'll show you how we made an emoji keyboard with the Adafruit cutie pie rp2040 and the one by four neo key Emojis are pretty easy to use on a mobile device But they're actually kind of annoying when you're on a desktop or laptop This project takes the macro pad approach and lets you press a single key to make those emojis happen One button press sends a keyboard shortcut searches for the desired emoji and then uses the return key to append it On mac os the emoji pop-up window lets you pick and search for emojis using arrow keys You can navigate and use the return key to choose your emoji The Adafruit cutie pie rp2040 is the perfect little circuit python board for this project There's no soldering required and you just connect the one by four neo key with a stemma qt cable With kale sockets, you can easily swap out the keys for your favorite cherry mx compatible switches Our little 3d printed enclosure is a minimal design that snap fits together and keeps everything compact The circuit python demo code for this project by liz clark uses the neo key and the usb had library You can customize the key codes and dedicate each one to a different set of commands Liz put together a code walkthrough in the learn guide so you can get a nice breakdown There's two different versions of the code one for windows and the other for mac os mac os big sir treats the pop-up differently So there's additional delays needed to properly search and pick emojis A really cool feature is the neopixel leds will light up a different color for each key and stays lit while emoji is being activated This works as a nice indicator so you're less likely to span the keys which can definitely still happen These keycaps are relegionable so you can add little inserts to decorate each key I used carter nielson's pdf template to print out a sheet of my favorite emojis Using an exacto and my digi key ruler. I carefully cut out each square making sure to trim along the inside of the dash lines This is a pretty easy way to add that extra level polish to your project for fairly low effort Having a full color insert with emojis directly on them is a pretty sweet way to label your key switches Each key cap is two pieces. The top cover is clear plastic that's not fits over a gray key cap I found it easier to remove the top covers when the key cap is secured to a key switch Just fit your fingernail underneath the top cover to pop it off These inserts are sized to perfectly fit inside the top cover Once inside it's easy to press fit the covers back on to the gray key cap They're actually symmetrical so you can orient them in whichever way you like If you're looking to design and 3d print your project be sure to check out our 3d models of adafruit boards and components Here i'm using a model of the cutie pie and the 1x4 neokey which features all of the onboard components They're available on github so feel free to download them and use them in your projects To build this project you'll need a few parts and hardware which we have listed in the description of this video and in the learn guide The 1x4 neokey has four mounting holes which make it easy to secure to an enclosure using m25 hardware I like to insert a single screw through one of the mounting holes and then fasten the standoffs while holding them in place Repeat for all four holes just be sure to install them on the correct side of the pcb Once the hardware is installed just line up the mounting holes on the bottom cover with the standoffs Like before start with just one screw and work your way through all four mounting holes The standoffs and screws are both really short so the pcb has a pretty low profile when secured to the bottom I designed a built-in holder for the cutie pie so it's easy to install with a little snap fit action Start by inserting the board on an angle so the pcb fits under these little clips in the corner Slightly flex the cover to fit the cutie pie underneath the second set of clips This will keep the pcb secured so it won't pop out when connecting a usb cable Then all that's left to do is connect the stem of qt cable to the 1x4 neokey and plug it into the cutie pie This is my favorite part of the project The frame snap fits over the bottom cover with the large opening lined up with the cutie pie's usbc type connector The four key slots on the top cover line up with the 1x4 neokey and just snap fit into place You'll want to orient the key switches with the sockets so the pins are going straight into the sockets Lastly you can add your favorite keycaps to each of the switches to finish this up I really like how just about everything in this project is modular including the code switches and even the keycap inserts I hope this inspires you to check out circuit python in your next project and share your projects with us on aetherford's weekly show and tell Okay, don't forget no paid drive back on wednesdays 3d hangouts every single wednesday At 11 a.m. All right. Lady. Are you ready? Yes All right this week's ion npi is from u blocks We're our favorite gps and bluetooth module companies special thanks digikey for helping up these segments Yes, every single week. This is where we will show you where to get the Ion npi. Yes product introduction. So what? Okay, so this week So I check this out on uh, I go to digikey.com slash new and I check out the what's new I kind of read every every blurb and I decide what I think is Is the niftiest new technology of the week and also I try to make sure it's in stock So people can actually buy it which is a new challenge that we're living with So this week we are going to look at the u blocks angle of attack the ao ao a 1 dev kit This is uh, there's two dev kits as the ao a 1 and the ao a 2 the ao a 1 is less expensive and it has One, you know transmitter. That's the thing on the right and then One tag that's the thing on the left and these are used to implement The new feature of bluetooth low energy 5.1 a lot of people think of bluetooth like 4.0 is bluetooth low energy But 5 and 5.1 added a new capability called angle of attack analysis and angle of departure analysis and basically What this is for is it allows you to solve and what I call an age old well trodden problem or challenge in electrical engineering and You know industrial design where you want to track something indoors and you want to know where it is in 3d space and this is a It's not shocking to people who've tried to do it But for beginners, they don't realize just how incredibly hard this problem is It's really really hard to know where something is in 3d space So, you know a lot of times when people think about okay I want to find something in a room. They think of like using a vision system I thought this I saw this cool image from wikipedia From the ibo dog because we were talking about ibo vision recognition At dinner a couple a couple nights ago and you know, there's a robot dog And it has a camera and it can recognize this pink ball And the the ball has to be pink and it has to be round And the vision system can recognize where it is in the room And it can use like some triangulation to kind of tell how far it way it is and what direction it's at And this is what you know, this is the closest approximation to very basic organic life Vision recognition systems, right? There's there's if you watch nature shows There's shrimp and they're like they can detect where the sun is or where the moon is, right? And that's the the most basic kind of vision recognition Um, and if you want to do a more object detection Some more complicated stuff you can use stuff like open cv or tensor flow Again, it's a vision system You do have to have really good lighting the thing has to be recognized within your system But you can kind of detect where it is in a room and you can also again, you can use Some mathematical analysis to determine kind of where it is in the room, but both of these really depend on Having the object to be fully visible and it has to be a recognizable shape And you know having very good lighting if it's obscured it won't work And that that's the that's the challenge, right? A lot of people have object detection recognition systems That use vision, but if that thing is you know, if that You know Bull is behind the computer obscured by the computer the computer the vision system won't recognize it When people think a lot about you know You know detection of where something is Location detection of objects a lot of people think about GNSS or GPS Positioning systems that use satellites. This is our you know very popular GPS module And these are really great, but they're only really great when you're outdoors GPS does not work indoors, which is kind of a surprise Not surprised, but like a lot of people forget that they're like Oh, why don't I just use GPS indoors and the answer is you can't you can't use GPS indoors It has to be outdoors and you need to have and be able to get a good fix and even then Because of the way GPS works you're not going to get precision or accuracy better than about 10 meters If you want to get better Accuracy you can use something called RTK, which we covered also you blocks is there, you know, they have premier RTK Hardware and designs that you can use check out this video, which we did last year around this time about the RTK ZED f9p GNSS RTK modules These are also to be used outdoors. Oh, they can I think they can be used semi outdoors semi indoors And they do a cool thing that combines Time of flight and GPS to to get you centimeter level Location detection, but again really good for outdoor things like drones or robots that are outdoor robotic cars Those sorts of things use RTK again not going to be good for indoor object recognition All right, so you're like well, what what can you use for indoor object recognition? Well, you know one of the things that Is used now and and i'm not going to talk about time of flight because time of flight is still For you know wi-fi is is still under development. We have we haven't really seen anyone use it yet Although I know it's it's being developed and worked on Um, but traditionally how you would do indoor recognition even now Is you'd use something like a bluetooth beacon So people who know, uh, you know, you have a tile or you have like the the apple itag whatever those those use Beacons and one of the things that you can do is You can use a you know, sometimes I say like something that's a side effect is also something you can sense so the farther you get away from a Two wireless devices get farther away from them each other The signal strength drops and that's bad because you know if you're a couple hundred meters away from a wi-fi hot spot You're not going to get You know good data transfer you're going to drop a lot of packets You want to be really close to your wi-fi router to get good signal and you want to have a direct line of sight Well, you can take advantage of that property Um and use it for detecting where something is in space. So you see here in the middle You know, you've got um a beacon and if you have three um transmitters that are transmitting Or receiving the beacon data they can Kind of use the signal strength to kind of sort of triangulate where the object is Only good for like a couple meters. I think it says here three to four meters also suffers from Signals bouncing off of each other and off of walls It's not great, but it's kind of what people use now. The good news is it's really cheap to implement It's very easy rssi is built into like every radio chip. You don't need anything special You can you know, you can use a variety of different chip sets to do rssi Targeting, but you're only going to get that three to four meters so what's interesting about This new bluetooth 5.1 capability is and this is something interesting that you know as I as I was Reading about it. It doesn't do rssi like distance detection or time of flight distance detection. That's something different. It does Angle detection it'll tell you the angle of where the object is But if you have multiple angles like you can use that again with if you have fixed points and you know where they are And you do the angle calculations you can use it to detect where something is in 3d space So you would put you know one of these you know detector transmitters in each of the four corners of your room like in Yeah, this this you know mock up here and each one knows the angle and then you combine that data together Boom you have the location in 3d space of your object um You know, there's some math behind it, but the math isn't so bad You know, you do need to have these kind of special funky Um, you know transmitter base stations and I'll show it on the overhead Um, because this is kind of what you're paying for So yeah, so this is kind of interesting so this is you know, it's got a uh, you know bluetooth 5.1 module here. It's got some buttons and it's got like an arduino kind of shield sort of shape and Debugging everything. Um, but the thing that's really interesting about it is this Intense antenna array It's got one two three four five antennas and it's got like this cross shape, which is also I guess part of it or no, sorry. That's the uh indicator. Pardon me. That's the le the indicator But it uses these antennas to determine The angle of attack the angle of where it is and one thing that I thought was kind of interesting is they're like Yeah, it's not distance and yes, you can use it to determine distance by again doing this triangulation But there are some situations where you might actually really just want the angle you want to know Where somebody is coming at towards you or you know, um, we'll show the video Where an object is with respect to a camera? Okay, this is available on digikey Yeah, so the a01 the xplr a01 explorer I don't know a01 angle attack gives you one tag and the tag is you know, you can make your own tag The tag is really just an there's nothing super special about it. It's an nrf 51 Sorry nrf 52 8 33 But the thing that you really want is this thing and then there's the a02 kit Which is the same part number but a02 and that one has four of each So that's where you want to do real multi multiple devices Detection within space. Um, this would be really great for Just angle angle of attack where is something in relation to This, you know transceiver All right, okay, and then we have a little bit of video. There's no audio. So you want to do a little bit audio Yeah, this is you know, this is a really cute demo and they have a blog post that you know, we'll link to You can see this engineer showing off. There's a pan tilt module and there's a camera and She's holding or they're holding a tag and As they move through space again It doesn't know how far the person is but it knows the angle They're at in respect to the base of the camera So the camera can pan around to find them and I think it shows that you don't need to have you know three Transceivers you can really get away with a lot of there's a lot of applications where you can probably get away with just one All right Okay, don't forget the good start 10% off everything was chopped. All right, let's uh, get new products All right first up Okay, we finally have these in stock. I mean these are new not new whatever we we had them coming soon for a while This is the po e Two hat for the raspy pie. I believe it's for the raspy pie three b plus and four only so watch out You can't use it with older ones, but it plugs right in and it has this a really cool flat inductor It's got a much better heats sink fan thingy going on. Um, I think it's a it's less bulky It's um, probably got better performance. Uh, check out the specs. It's the same price We have some in stock and if we're not sign up and we'll get another shipment Okay, next up. Okay. We also have an stm 32 h 750 kit. This is from we act They make the quote unquote black pail stm 32 F4 11 board that we carry and I just really like this dev board. I'll say we didn't make this dev board You know, we're basically stocking it as is Um, we don't even have circuit python support necessarily for this chipset yet But we just thought it was such a good dev board that for the people who are interested in exploring this Ultra powerful stm 32 h7 chip. I mean it's like 480 megahertz. It's got 480 megs of q-spy flash It's got like a megabyte of ram. I really like this dev board. It's simple to the point. It's got the chip sd card usb c You know bootloader dfu button a couple things on the bottom some flash camera slot You get to really experiment all and all the breakouts. It's a great way to experiment with This new chip and you know, I just want to clarify It's meant for advanced users. I don't even know that there's an arduino core for this chip But uh, if you're if you're ready to rock out with sts development system This board is for you We also finally got our shipment of colorful clips. Um, these are from leeborg cyborg Um, these are you know, they're fun festive Tropical alligator clips. Um, they come in these cool like lime green. I think like tangerine orange uh pink my hair pink Blink a purple and uh, you know like a pastel blue You know, we have all your clips that are like the regular colors, but maybe you want something kind of cool kind of femme kind of Tropical so shouldn't be boring. Don't be boring when you can have these beautiful alligator clips I love it when people take something That has classical colors and they give it a twist. So these are super cool We start stocking. Yeah, also if you do workshops and these are yours You know, you'll be able to identify them and be like, hey, those. Yeah, nobody's going to steal your alligator clips And you got or they're definitely going to steal them Next up, okay, we've got uh, this these are dhc 20. There's a couple different names from but these are basically ht 20 Temperature and humidity sensors. We really like the ht 20. These are an upgrade from the dhc 22 They are true i-squared c sensors that come in three different shapes. So we've got this like four pin module shape Plugs into a breadboard. It's very inexpensive if you open it up You see inside there's an ht 20. There's a thing on the top and um, there's also a capacitor And who carry a good capacitor is always helpful and two pull-up resistors I love that they included the pull-up resistors 10th of a cent but really handy. You can see the pin out there. It's also on the page on the back There's the nicely engraved specifications. This is a really good low-cost temperature humidity sensor Please everybody for the love of god, stop using dhc 11 and dhc 20 choose and use these instead We have python code. We have circuit python code. We have an Arduino library It works wonderfully and you don't have to deal with like annoying timing stuff of the dhc 11 and 22 Speaking of which You don't have to use the am 2301 either because we've got the ht 20 version of uh, this as well It's kind of like an enclosed shell version easy to mount got four wires again What's inside ht 20 capacitor two resistors Wires easy to use easy to connect specs on the back Please use this there's even more Next up we've got the uh durable version, you know, this is I will say it's not waterproof But it's it's much more durable and protected. It's got this kind of um mesh bubbly Cover that will protect it for use outdoors. It's got a mounting, you know clip and some screws and everything and inside What do you know? It's also an aht 20 I squared c temperature humidity sensor Love these things. So um these three they're all part of a family You know, if you just need a breadboard get the cheap breadboard one want to mount it outside One a little bit more durability get the am 2315 version, but they all use the same code Really like this sensor strongly recommend it. Please stop using dhg 11's and 22's Okay, next up, uh, you notice that the ultimate gps modules that we've been stocking We've had to revise all of the breakouts and the shields and everything because For reasons that I do not understand the maker of the ultimate gps module that we've used for you know a decade or so Stopped making them. However There is another company that makes an equivalent module. It's the same similar chipset. It's the next generation chipset It's pin compatible And best of all this one also supports Glodos, which is the russian gps alternative so you can Also, you know, you can use this even if you aren't getting gps satellites You can use the russian satellite system to also get location data And did I mention it's pin compatible? Did I mention all the same software works dimensions even cheaper than before? It's a little bit thicker because the antenna has to be thicker to pick up I think both satellite systems But we've been using this module with great success Strongly recommend it as a replacement for the previous Module and again, it's pin compatible. You don't have to worry about it. All right And we have we have a star of the show, but I kind of feel like The next round of products and then the final product is a starter show. So we have a bunch of keycaps We've got some fun keycaps. So, um, we we kind of went on a little bit of a tear We decided to get a bunch of custom keycaps that were inspired by that one to last my life Yeah, so first up This is the git log of the git logo is under creative comments. It's by jesson long. Thank you for making it available Um, we just thought it's a cool logo and maybe you want to have the back of all of them is like this Yeah, the back of the same. So these are etched glow-through keycaps. So all of them, you know, they look Great, even without a light behind them But if you do have a backlit or underlit keyboard, they're going to look really good because you're going to have that glow And so, uh, I should be clear. So these are ones that we came up with we didn't talk to anybody about this This is just me. This is just these are my favorite things So I was like, what would I want on a on like a macropad that was like, what do I do with coated? So some of these are a little bit snarky. I thought will be funny. So, you know, won't fix which is, you know, a funny If people do they close things with won't fix, but it's a little bit of a joke with us Um, internally where we have a bug that's so difficult. We're like struggling with it and we're all like Ah, you know, what if we what if we just close it is won't fix and just ignore it Uh, we we don't usually do that, but maybe it is a feature not a bug Yeah, and this one's always funny because it's hate fork. It's hate fork and it's what people do during a project I think spite driven development is a powerful motivator. Um, and it's true. There are a lot of I mean, there's a lot of history of computer science that is hate forked A lot of linux is hate forked a lot of operating systems and tools are hate forked a lot You know web development, there's a lot of hate forking. I mean, it's a little bit facetious I said, you know, there's no hate here, but there's a little bit of the like you see some code You think you can do it better? I think it's funny just to have it on your little keyboard because you're like, you know what? I can hit that button at any time So then next up next up a pull request, uh, you know, I'm trying to intermix the little, you know, a little bit, uh A little bit of bitterness a little bit sweetness We love pull requests. We make them all the time It's a great way to contribute and I think it's one of the most powerful things that we've added to Programming, you know for a long time we've had open source, but I think the pull request is sort of the next generation it's how do people contribute back and We finally made it as easy as pressing a button And also here's a button. All right, and then the last one before the last one is this is uh looks looks good to me This one is I'll tell you this one is is uh for tan newt scott our developer who um, you know sort of Well trained us well into doing Pull, you know pull request reviews. We didn't used to do them And scott was like we should really do them and I was like, ah, you're right And so we started doing them and it's actually really improved our development process And one of the things that uh, I saw you know scott was doing a lot of reviews early on um, and scott would would put lgtm exclamation point or or you know period In the reviews and I was like, what is that and it was it's like it's like a little bit of a googleism Looks good to me. It's a it's a short way of doing an approval of a pull request. So I thought all these things together I think this is this is kind of like the history of what I do Yeah, we had another one, but it just won't fit and I don't know if we're going to do the acronym It's like works on my machine Yeah, I think it looks good to me. Hey forker won't fix kind of kind of cover that all right and then last up This is this one's a little different This is official official. We worked with github and got permission to make this. Thank you github Thank you Github. Thank you martin in particular and we were able to make this an official thing We can sell it. We have a license to do this github is super cool about this I love how they approved it. We sent them a photo mock-up and I think on their internal Yeah, or whatever. They're like, this is so cool. They're like, this is so cool approved And I was like, I love it when you don't have to go through Legal. Well, no, we still had I still had to do it legally. No, no, but they you know, they they were just like It's this great. So let me plug this. This is what they look like off So I'm turning this. Sorry. Yeah, that's what you want, right? Flippy Well, we want to the wrong way. I think we want to flip Oh, sorry, I will How did it get reversed? I don't know Okay, well, whatever. I'll just turn upside down. This is the uh, you know, this is the overhead that this isn't even It wasn't even supposed to be survived Shouldn't have survived until now. This is the one that died last night. Well, this is fun because this is now You know landscape. So let me autofocus Yeah, I don't know why it's doing that. You know what? It's cool. It doesn't matter. Who cares? So you say I have some non You know, some just generic key caps. These are putting key caps And then at the top you can see the demo showing it just swirling through the colors And then I think if I press it, it gets a little bit brighter, which it just makes it just as dim You got the won't fix got the looks good to me got the Hate fork. Oh when I press it, it turns white so you can really see the color poor quest Octo cat and Git So, uh, I just think you know, if you're gonna have a mechanical keyboard Why not just have a little bit of a ridiculous Key switch on there. So I really love the camera is actually even backwards right now. Is it well Yeah, who knows man. Wow, that's so cool. Yeah pound won't fix won't fix. Sorry. Yeah This is the overhead that um died last week And uh, I thought it was back to normal, but apparently it's not that's cool I don't want to mess with it I'm gonna try to Yeah, there you go, like let me see if this works on my machine Yeah, you know, it looks like anyways, we have these in stuff. We got a bunch of them And uh, we'll be making more because we think it's fun to have custom and this the official one And I don't know how long we're gonna be allowed to do this So when they're back in stock because we got through the first batch really fast, um, probably should pick up one Yep, nothing lasts forever Okay, start a show beside you lady Everyone in discord is a key cap. No, it's a round rectangle display. Uh, people know Adafruit. We love to have custom displays Breakouts and such and it's been a tough year for displays. It's um, they're they've gone very expensive But we didn't want to bring this one out This is a 1.7 inch diagonal 240 by 280 display and it's got a cool thing going on with it It's grounded rectangle. Um, this is you know, if you have like a watch like a smart watch or whatever You'll notice that they have, you know, rounded rectangle screens. And so these are, you know Designed for use in those cases, but I thought maybe people would have uh, some other use Okay, I have to remember this is yeah, sorry this Is this okay? No, I got it. Um, it works. It works So let me this is freaking out Um, so this display I'll say so you can see how it cuts off Um on the corner So this display I guess people like oh and you have to do some special memory mapping. No, it looks To memory in the memory the way you write to the screen. It looks like a square display. It's just literally those Corner it just you know corner pixels. They just don't show up Um, so this is a Um, you know, you could use it for a smart watch if you want, but it also just has a kind of a funky look to it Um, you just use it like any other st 7789 display nothing special about that there Um, 240 by 280 pixels. It's an IPS display. So it looks good even if you're Angled like this I think you know people are like making their own DIY smart watches. It's going to be a good use for that But it's got also got very high ppi. So any any sort of small wearable Or project and I think one of the things that's uh, we're trying out that's new with um, this TFT is you know, a lot of people really liked our stem at qt board system where Um, which is based off of spark phones quick. Uh, it's it's the same compatibility same pinout where you can use any um Anything with i-squared c would have the same connector so you can easily plug and play and chain them together And we thought um, well What if we did the same thing for spi because a lot of people have displays and especially if you're making a smart watch You may not want to solder it in you might want to have a flex display So we actually saw that df robot had um a pinout that they were using on some of their displays I thought this is really cool. We made ours compatible. It's three or five volt logic And we tried putting it on this display So going forward It will probably have dev boards that have this flip top flex connector That our tft's a little bit of plug into so you can just attach a display as easily as you would a uh, Stem at qt. So this is the first one. So hopefully by the time this video is a year old We'll have a bunch of products with this connector on them And let's do products Okay, don't forget to costar. Let's start 10 percent off every time you saw all right So I have some questions lined up, but we're going to do top secret. Um, go to adafruit.it slash discord This will read you all the questions. Um, we'll get to those in just one second. Let's do top secret. Okay Out of the vaults All right from the vault. Um Here it is. Oh the last trinket. I'm finally getting to it. I know people have been so patient Uh, come on. So for each trinket we have a character and some of the trinkets are not forever trinkets and I will Get murdered on twitter when I talk about our not forever Trinkets because they'll think it's nfts, but it's worth it. But um We have a character for each one. This is the little proximity bat and this is the one for Um, the proximity trinky that that'll be coming out soon. Yes, sorry I think this overhead really wants to like Give up the ghost. Is that what they say? We're not gonna let it it wants to we're gonna reanimate it. Yeah It wants to Pardon me. It was working and then okay great. Uh, so proximity trinky. It's a trinky. So it plugs in It's got a samd 21 regulator reset bun and over here. This is an apd s 9 9 60 Which is a proximity? Light and color sensors kind of a nice all-in-one sensor. That's also pretty expensive. It's only a dollar or so Two neopixels and two capacitive touch buttons So I actually did finish the design and then of course I ordered the wrong thickness PCBs So thankfully they didn't get into the store. Um, and we did a very small run I'm gonna order new PCBs maybe in a week or so. This will be in the shop Okay, and that's new Not not new not new not new it's top secret. It's not secret All right, so we're gonna roll right in the questions. Yeah question it through Yeah, I got a bunch lined up. Yeah, okay, so You're ready. Yes. Okay, uh, I'm gonna hit the ones from back in time and then we'll get to the one Is there any chance we'll get the high res uh about 1080p small five seven inch screens that work with the pi and other hdmi sbcs um hdmi, maybe not because those are going to be mippy displays, but I know that um, I was talking with uh Timo Timon and There is some relaxation of the dsi Interface on the raspberry pi. So there's some promise there okay, uh Next up suggest a controller board for low power usage and hibernate function that can wake up in under a second Any kind of it moved wake up now a circuit example Oh, you know spark fun has an example where they used accelerometer and and they use the um The interrupt output to wake up any anything will wake up in under a second. That's a not a very That's not a very Short amount of time most things wake up in a couple of milliseconds. Okay Next up Someone had asked, uh, what do we use for dns? Our answers are probably the same one to other folks at 1.1.1 on 1 or 8.8.8 Yeah, they could set it for you Seven seven wait 18 18.0.70 dot 160 That's the mit dns. All right I still remember after 20 years any chance of creating a radon detector breakout the sensor seems hard to find for a regular person Oh, that does sound hard. I don't know where to get a radon detector. Maybe I'll do that for the great search Oh, good one next up. I'm making an e-ink display board I was wondering if there's any 12 volt shot seed diodes that are okay to use with the 30 volt ones that they have listed I'm trying to use what I already have. I'll probably get the mbr 05 3 0 But I have a lot of the 05 2 0s I think the voltage generated for e-inks is around 18 volts. So 12 20 is cutting it close Um, you could probably get away with it All right Next up still going through these Uh, I built a bistable transistor circuit over the weekend and use nrf ppk2 profiler to check the power consumption Does 8 milliamps seem excessive for just as few npm transistors resistors and caps? Any tips on how to make it lower power 3 volts for a battery project? Transistors are not npns are not low power You need to use MOSFETs for if you if you want to avoid because you're probably biasing them And that bias current is what you're you're measuring. I don't know your your circuit But I'm assuming that it's the bias. That's what is sucking up the current um You'll you know Doing things in discrete logic. You have to be very careful. It's it's not as easy to be low power there's a lot of Tricks that integrated circuits used to to reduce power consumption. Yeah Has they ever considered diving to 3d printing and trying to revolution at the space? Well, um, I I feel like it's already been revolutionized. Yeah, so just to give you context I was living in seattle Bre Pettis was a school teacher. I convinced him to quit being a teacher come work for make the two of us moved out to new york city He started doing nyc resistor Also was working doing an etsy thing did a tv pilot called history hacker came out the night that obama was elected remember that didn't get ratings decided to then start makerbot and uh I Live through watching 3d printers I've heard brie say this. I think publicly, but I'll you know, I think it's probably okay in the end People want like 150 dollar printers and so the revolution of this space for the most part just became low cost and so Yeah, we could probably go to business. It's really it's really it's really hard to bring any innovation to something that people don't want Yeah, okay for for what it could do and the expectations are really high So I don't think we'd be able to to uh to do that But always interested we'll see For all the silicon that you have to import have tariffs become unpredictable and can be factoring your bottom line to government He needs to kill off silicon tariffs agree having tariffs along with the crazy silicon shortage Uh price gouging is nuts. Yeah, so we yeah, so the the tariffs are consistent and we have we've seen Products their prices have been raised. Um, I don't know this at the silicon. I mean, here's the truth silicon Actually often is not made in china. It's actually often made um in other countries and so Not sometimes it's packaged china, but not everything is affected by it. It's actually not silicon It's kind of everything else that is affected Uh, is there a point when you where you start selling more consistently product-wise? It's just talking about products a lot or providing enough products to make something with I'm selling more each month But I'm not sure because I'm making more boards or more people are seeing my stuff I don't understand the question It's your point where you start selling more consistently Yeah, I think you know if you're selling if you're selling a product you want to have your your cash cows your mainstays and also Explore and add more. I always recommend if you have a business to release something new at least once a quarter once a month Is is ideal one of my mentors and this is when I was in advertising Said to me something and I've applied it to other stuff. The business is new business So if you're making new products all the time You'll always be able to sell some of the things that aren't the new product But the new product is the way to keep momentum keep pace. Oh, this is why we do the show every week This is why we do this new products drive a lot of stuff. Yeah, okay Any chance of a usb c trinky? Yeah, we'll think about it on the room Any tips on how to store transport lipo batteries like a hard shell or something hard shell is good Shouldn't be fully charged I don't have the recommendations but look online for how to ship lipo batteries safely. There is definitely guidance from Government agencies and shipping agencies telling you how to do it. Yeah Uh, could I make an adafruit game? Yeah, maybe I mean like we wouldn't want it to be respectful Yeah, I would I would be careful because like a good example is I wouldn't want adabot to like fire a gun You know things like that. You could do something that is inspired by adafruit, but doesn't necessarily Yeah We're pretty chill. Uh, make a game or just make an outline send it to me. We'll check it out Uh, can you put arduino and cb code on any given board? Not any given board, but a lot of boards a lot of boards Yeah, anything like Anything that can run circuit python can run arduino Doesn't work the other way around. Yes, and I think that's it that is all the questions for this week Thanks, everybody. All right. That's our show tonight everybody. Don't forget the code of staro staro staro Oh, there was a question from twitch. You see I'm bubbled up Uh, because we didn't go over there Recommend a chip to track quadrature encoder counts high speed that takes weight off a microcontroller Maybe iSquared C. I think that Allegra has a couple chips. They're not cheap They are not cheap, but they do they do make encoder iSquared C or spi chips. Okay All right, um, so anyways, uh, thanks jesse may behind you. Thanks jesse may special thanks to all of our Teams that are working here All the customers that keep just going. Thank you. Uh, and then once again the code of staro Because we saw suicide squad We're not part of the marketing team of no wb or dc or anything We just watch movies sometimes and sometimes we see pretty cool our stuff in it and that's kind of cool enemy staro I mean like just wanted to look at the stars. Yeah All right, so that's our show. We'll see everybody next week. Here is your moment of zener
