 Life in New York, it's Ask an Engineer. Hey everybody and welcome to Ask an Engineer. It's me, Lady Aida, the engineer, with me, Mr. Lady Aida Phil. I'm camera control behind the scenes work, making this all thing happen. We've got an exciting show for you tonight, jam-packed with videos and stories and products and discount codes and calculators from the 1970s. All that and more on the next hour. The most interesting thing you can do for the next hour, believe me. Why don't we kick out? Yeah, I think so. Take off the show. Mr. Lady Aida, what is on tonight's show, please? On tonight's show, the code is inductive, 10% off an Adafruit store, all the way up to probably midnight. Or when I remember to turn the code off. Inductive as a code, 10% off all the items in stock. Get it while it lasts. Talk about our Adafruit live series shows, including Show and Tell, Time Travel, Around the World, Makers, Hackers, Artists, Engineers, News and More. Help Wanted, some jobs from the jobs or jobs.adafruit.com. Main New York City factory footage, some footage around the New York City factory, which we call Adafruit. And then also a time lapse from across the street. Some 3D printing, two projects from Noah and Pedro this week and a cool speed up, especially if you've been watching things on the Marvel universe. It's a theme. Got an MPI brought to you by Adafruit and Digikey. New products, we got a ton this week. Tons. Top secret, I'll have a bunch. Tons. We'll answer your questions. Tons. Adafruit on Discord, Adafruit.it slash Discord. Congratulations Discord for your $500 million funding that you got today. Damn. Woof. They decide not to sell to Microsoft. They just took a bunch of money. Yay. Yeah. We'll see. Maybe. 30,000 of you are over on our community on Discord. It'll be 31,000 soon. All of that and more tonight on, you guessed it, ask an engineer. Okay. Yeah, we have a really jam packed show. There's a lot going on. We're back on our bullshit. We're back on our engineering. We're back on our content. We're doing so much design work, putting so many new products in, doing a lot of videos. A lot of people are back from vacation, well-deserved, well-needed vacation. So let's get right into it one after you. Yeah. Two and a couple things there. No, it's cool. There's a lot going on. A lot going on. All right. So first up, let me just do COVID related news. Not gone yet. No. It wants to stick around. I know. We're all done with COVID, with us. Someone's saying we got a little bit of clipping actually going on here. I think you're a little loud. I'm like at six and you're at like zero. We're gonna go to this before so it's not just like a COVID thing. Yeah. Let me... So we had a guest on our show last week so I had to change the audio for that. And then this week, I'm gonna just change this a little bit. So give me one moment. All right, we'll see how that goes. Anyways. That's fine. Oh yeah, that's much better. You were like at the time. I will say. Okay. All right. And anyways, so here's our COVID news for the week. We're just like everybody else getting news. So the way the federal national mandates are gonna work, it's part of OSHA. And over the next couple of weeks, the rules will be finalized. Companies over 100 people, we fall in that category. We'll have to do it. And just did a meeting with our employment lawyer. And just so you all know, because I feel like it's a good idea to share this stuff, just like we do with all parts of the business. So we're starting off with is an employee survey and they're going to say if they've been vaccinated or if they're going to be vaccinated by one of these first dates, we're probably like 99% there. If not 100, we'll see. Just based on how we work with each other and how we've collaboratively tried to get through the last 18 months together, but you never know. So that's what we're doing first. If someone were to ask me, because I've been talking to lawyers and other business owners and people who are in the HR industry, I really think spending time with your employees and if you don't have some type of weekly meeting that has other things other than COVID news, it's never too late to start those. But really giving everyone the information and showing them each step along the way what you're doing and why and how there's things that the state or city or federal government will require and then there's things that your own company can do. And I think getting as much input from everyone and like, I know that this is all like, try, it's all tried and unamusing and it's in like business books about leadership and everything, but usually leadership is taking on the tasks that no one wants to do and then excelling at it. And it's a weird thing to say. It's like, it's often stuff that no one wants to do. That's what leadership is. Yes. So if you could break through that and have sometimes uncomfortable conversations with people, I've taken folks to the CVS and help them get vaccinated. So as other members of our team, I think that's the right approach, but I understand how other companies can get where they're at. So one of the things we're not gonna do when I saw in the news, it's like, oh, like United is going to raise the healthcare prices for the unvaccinated. They're going to do this. They're gonna- And let's pay time off. If you can't do that. It's like these like forms of torture for coworkers. And I think they could get to the goal of what they have, which is a safe working environment with folks getting vaccinated without coming up with these torture ideas about how they're gonna take things away and how they're gonna just basically be mean to people that on the other side of this, they're gonna have to still work together. Yes. And I think just saying like, hey, like how can we make this happen together as a better approach? Anyways, maybe we'll ask me in two weeks how I feel about it. But anyways- It's a collaborating on code, but with absolutely everybody on earth. Yeah. So I think that we'll be the, just like a lot of things Aideferit does, I think just our approach is a little different. And I think we'll have everyone save, everyone vaccinated, and we won't have to do all the terrible things that companies are like coming up with to get them there. I think there's a way. But again, ask me in two weeks. Okay. So that's the COVID update news and more. I hope that helps some folks that are running companies or working companies too. You can send them a link to this. There is a way usually to get to the goals together. Yes. For the folks that are gonna use the code tonight, it is inductive. And- It's 10% off. You also get free stuff. Just about everything in the store, also yes. If you order from Aideferit.com, you will get some free stuff. Free stuff we have is $99 or more, a free permapurto half size breadboard, a wonderful way to take your project and make it permanent. $149 or more, you get a free STEMI QT board. You have a range of sensors and boards and drivers and all that good stuff. You'll get a different one each time. If you make an account, then we will give you a different one for sure, because we know which ones before you sent you. If you don't make an account and check it out as guests, we'll just get you, you'll get a random one, arbitrary. $199 or more, a free UPS ground shipping in the content of the United States. That's trackable, reliable shipping. And $299 or more. You get a free Circuit Playground Express, our favorite all-in-one development board, made for people who want to make projects, do electronics, do counter-code and they don't want to do any soldering. It's plug and play. All you need is a USB cable, which you probably have. Look under your desk, it's there. Okay, we do a whole bunch of live shows. We do these every single week, especially thanks to JP this week. Did the show until next week, is no Pedro. And I glanced over because I was wrapping up show stuff. It's cool, they had synthesizers and robots. Yeah, and Jay was there. And it was Jay's birthday not too long ago. I sent some Adaford store credit and I think there was some Adaford stuff going on there. So I'm gonna watch that as soon as we're done with the show. On Sundays, we do Desk of Lady Aida. The first part of Desk of Lady Aida was what you were working on. What were you working on? I'm gonna ask, okay, what was working on? Oh, that's right. I finished up my UPDI standalone programmer. So I need that to be able to make boards with AT Tiny chips that now they use a one-wire programming system called UPDI. So I kind of walked on this couple of months ago and then I have to finish it up. So I just showed that I got it working. You can have program chips and verify them from an Arduino sketch so you don't need a computer, which is awesome. And then I sort of showed how I build a tester. So I started the first half of making a tester breakout that will let me have a Metro M0 or M4 program test and verify a board in hopefully a couple of seconds. So that's kind of one of our secret sauces for how we get boards made so fast in-house is that the test procedure takes 10 seconds or less. Okay. And then we do the great search. That's with Digi-Key. And LaData uses our powers of engineering and decades of searching the internet for parts. I am so good at it. What did you find this week? I'm not happy there's a part shortage, obviously. I hate that people aren't able to get their parts, but I will say I was made for this. Like I was born into the part shortage. I'm like Bane, but for like finding components. I was born in the shortage. Pretty much. Not like today, like I found those LiPoly charger chips. I snapped them up like that and Mary was like, hey, so you got those so fast. Anyways, it's my thing. Anyway, so it's kind of what I do. The CP 2104, one of our favorite USB to serial converter chips. We love it. We use it in our feathers. We use it in our breakouts. We use it on our metros. It is NRND. I think this is the first time we've talked about NRND part. Non-returnable, I don't remember what the D stands for, but basically, this is their last chance to... Oh, sorry, not NRND, sorry. NRND is not recommended for new designs. There's a different thing for non-returnable. Not recommended for new designs means you can still buy the chip, but they don't recommend it for new designs because it is going to go end of line soon. So they've moved from the CP 2104 to CP 2102N. So I talk about that chip and also I show you some other variant USB serial converter chips that you can check out as well as some hints. I've used a lot of different ones and so I have a little bit of feedback on the different makers and models, but luckily there even is CP 2102N in stock at Digi-Key and I show you the only thing you have to do the schematic to change it to make it work. Okay, tune in this Sunday for another one. All right, JP's product pick does this every week. It's the only live show that I know of in the United States that broadcasts from a product page. Inside the product page and you get like half off. Yeah. And we've kept track of how many products we sell on each show where more people are tuning in to buy more stuff than half off. Oh wow, okay. That's true. All right, so let's do this week's highlight. FM radio breakout. I've got a little sort of number station type of thing playing right now. It's gonna play on the initial frequency. After six seconds, it's actually going to change itself and I'm gonna tune it down to 90. Mr. Cunningham said you must mean the Camels in Egypt. A couple seconds later, it's gonna go out. Going on. Now I'm gonna retune. Land and ocean, Earth's land. And there it is again. Oh, not as good as even reception there. So you can imagine that you could have this happen programmatically. You could have it changing at random intervals. RDS is how you end up with some info on your usually car stereo display that tells you the artist and song. So that's the product pick of the week. It is the FM transmitter breakout. Okay, and tomorrow is JP's workshop and right before the show started, JP sent me this little clip. This is a preview of what you'll see tomorrow. I'm looking forward to Radiohead re-releasing Kid A over and over. It's kind of like your advice to me. Just redoing over and over again. Don't read the other books. There's two pieces of media that I say just do the same thing over and over. And that's the matrix. Just watch the first one three times. And then Dune. I'm gonna watch the latest matrix that's coming out. That's different, okay? But I'm saying two and three and then Dune. Yes, just read the first Dune and then just glue the covers of the other books on top of Dune. And it's better that way. I hear ya. Okay, and then we also do Circuit Python Parsec on JP Show and then we have a highlight, of course, from this week as well. Circuit Python News. For the Circuit Python Parsec today, I want to talk about returning multiple values from a function. So what you can see here in my code is that I am importing from the random library, rand int, that gives me random integers, time so I can do a little sleep, a different macro pad, which takes care of a whole bunch of stuff with the display. And then I'm creating the macro pad object. Now I've created this little function that's called getRandomXY. This function right here, you feed it a minimum and a maximum for X positions and a minimum and maximum for Y positions. It returns the X and Y location using a random inside of those constraints. That fact that it can return both of those values is the cool part here because I can use just one function and a lot of different parts of my code can keep calling back to it to grab these two XY random values. Then inside of the main loop of the program you can see I'm casting a variable called X and a variable called Y to the return that we get from that function. So getRandomXY and then I'm saying I wanna go a minimum of 16 which is a little offset from the left and a maximum of 112, a little offset from the right and same for the Y axis, 16 and 48. Then I'm printing that to my little serial display. Go ahead and see that happening right there. So those values X and Y are what get returned from my function and then I'm just using this macro pad.displayImage a little BMP file and then its position is that random X and that random Y position inside of some constraints that my function returned and then we do a little sleep. And the result is you can see I've got this little blip this little sort of space invaders alien jumping around the screen there inside of my constraints and so that is how you can return a couple of values from a function inside of CircuitPython and that is your CircuitPython Parsec. Okay and this Friday, tune in to Deep Dive with Scott. I think this is gonna be the CircuitPython running on bare metal on a Raspberry Pi. I think so too. I sort of put in a request for it. Of course it's whatever Scott wants to do. It's Scott's hour but- It's got just, aren't got- It is pretty cool. Scott's been a lot of time on the Bluetooth though. Energy stuff lately, it's a really good spot and partly a little bit of dessert treat of doing that. It'll be on a Deep Dive no matter what but it might, it might be this week. Check it out. All right, time travel. Okay, first up this week on time travel we're gonna do a little calculator retro history with Phil B. This is a good one. Phil B is so good on the retro stuff. I watched it earlier today when I was putting together the show. Put your headphones on for this one. It's a good one. Hey look, it's some old calculators from 1973 and 1980. It's usually the LED displays on these that get people's attention but I wanted to talk about a couple different things. First is these always came with a slip case. It wasn't an aftermarket thing like your phone case. It just came with it. This one has a belt loop if you're just that hardcore. These things were built like tanks. It's not like they needed the slip case but it was a tradition carried over from more delicate slide rules. The other thing I've got to mention is the buttons which feel and sound delightful. That comes from using metal dome switches. The same as the clicky buttons on early joysticks. Newer calculators use either membrane or elastomer keypads. It's easier to manufacture and I won't knock it because that does make them more affordable and accessible to people. So I like that. It's just the new buttons don't spark the same joy. And a reminder, we have less than 100 slots open in a box already. Halloween is about a monthish away. So here's your chance. You should sign up for Aida Box. You'll get this box. You could get a year subscription. You can give it as a gift. Yeah, we might not have. We always have an amazing Halloween box. Yeah, and if you wanna give a gift of Aida Box for the holidays, it might be a good idea to do that now too because we'll probably be full for the holidays. Yes, JP's already planning the next video and you know they're gonna be good. You wanna be part of this. There is a lot going on for this one. Okay, Collins Lab. We do a Collins Lab Notes video every single Monday, Tuesday, Thursday, Friday this week. I'm picking one, the Pogo Pin one. Cool. Here it is. Pogo pins are tiny spring-loaded components which allow the board they're mounted on to make momentary but electrically sound contact with another circuit. They're perfect for test jigs when you need to perform the same QA test on an entire batch of boards. Position, apply pressure and repeat. The type of board you're testing will likely dictate which type of Pogo pin you should use. The needle head Pogo is a good fit for small signal pads dedicated to testing. The cupped head can fit over small solder joints such as the top side of a row of header pins. The somewhat intimidating spearhead works well for empty through-hole pads. And if you need additional stability or more contact with the test surface, the regal crown head may be a better fit. Okay, you can go to jobs.adafruit.com and check out our jobs board. We made this so folks can post their skills, get jobs, or if they're a company, they can post what they're looking for. And usually I would say every company, no matter what they do, has something to do with electronics now. Or coding or making or prototyping or crafting. And the innovations you see in the engineering and maker and artist communities, that's what employers are looking for. And so I think this was a neat one this week. One, this is a microcontroller C, C plus programmer. And then the other one, Stanley, Black and Decker, they're looking for electrical engineers and technicians for power tools and things like IoT, things like machine learning, you name it. And so they just posted that up on our jobs board. I mentioned it last week, but I also thought it would be good to mention it today. I mean the Black and Decker and Stanley, these are like really well-established American brands, so you can get a job there, I'm sure it. You're gonna be working with some of the best people making reliable tools. There's material stuff, it's like building a little robot. So I think that's kind of cool. It's true, they're little robots, that's a good point. Screwdriver, is it a little robot? Yep, you can use a screwdriver, a power screwdriver to power a robot too, because they've taken care of that. All right, next up. I thought on hardware news, gonna go over a couple of things and then the usual, I picked one topic that we're gonna talk about. Okay. It's gonna be a little surprising this week. What? Sure. Okay, well first up, congratulations. We mentioned this before, but we're up to 9,000 subscribers. If you haven't already, go to eight. It's now over 9,000. Over 9,000. That's a good old meme. Go to AdafruitDaily.com and sign up there. It's not connected to your Adafruit store account. We don't spam, we don't harvest anything. We made a completely separate site. Use those email tricks so you can see if we ever use your email address for anything else. We don't. Yeah, don't trust us. That's why I say it. So do that because after we hit like a milestone, like 9,000, it'll slow down a little bit. That'll only get like 10,000, but if you could, sign up. We'd appreciate that because you'll get all this delivered to your inbox every week. It's my favorite newsletter. Jebler, stop by. Check out our... You remember that? That was last week. That was last week. Check out our video and then also, Jeff's usually around in the chats on all that too. So Jeff got his picture taken. If you work for Adafruit, you get your picture taken and you get to hang out with Blinka. This is why you wanna be a core contributor to Circuit Python. This is one of the benefits. This is one of the benefits. Yeah. So lots of different things. We posted up about the study of open source hardware and the EU. There's a bunch of projects in addition to events and more. But this week, the thing I wanted to start to talk about is we ported Circuit Python features to Arduino. Yes, we learned things. Yeah. So I thought this was interesting because this is the snake wagon, the tail or something. But it's interesting because we did... I think we're still the... I like that graphic. Did you draw that? Yeah. No, that's Anne. Anne, nice work, Anne. I think we're one of... Now I'm just gonna say it because unless someone's... Someone all tweeted me if I'm wrong. We're the largest... We're the biggest contributor to the Arduino libraries. Yeah. And so as we were doing Circuit Python, we learned a lot. Let's do a lot of things. And then we had some requests for Arduino. We do a yearly thing. Like, oh, here's what we'd like to see in Arduino. And so we did get to this one for Arduino. And I'll go over some of the things that we had requested. But what is this... For the folks that do Arduino coding, they're gonna be like, this is the best thing ever. If you have code like this in your libraries or your examples, and if you write Arduino, you probably do this like wire write, wire send, and then you request and send, receive, and you're just tired of the same code over and over again. Especially if you're doing driver libraries for chips, where it uses like SM bus registers, where you write the register address, and then you read data from that address. There's so much boilerplate that's constantly redone over and over and over again to like read buffers, and what if you have to write, read or write more than 32 bytes, and then you have to do multiple transactions. Anyways, so one of the cool things about Circuit Python is because we did that, we basically structured it. I was like, all the things I didn't wanna do in Arduino, I made sure that we fixed and made working easier in Circuit Python. So doing stuff like register access and writing large chunks of data to and from, I squared C and SPI is a lot easier. And then I was like, I wanna take that simplicity, and something's also from Linux, by the way, Linux also has a really good API that we borrowed from in GPIO zero. But the whole idea of like write then read and prefixing and like, having it just be one transaction where you send and receive a buffer. So you can see all the code on here, all of it got replaced with that down there. And what's cool is is that there are platform by platform changes to how wire and SPI work. Believe me, I have found out they're not all exactly the same. And so all of that complexity is hidden now in a library and it's like, I just say here's what I wanna do and it will do the best it can, depending on the platform to have repeated stars or clock stretching or large buffered reads and concatenations and all that good stuff. So maybe we'll even support and SPI, we support software, BitBang SPI as well, and we'll probably add BitBang I squared C. So just like taking all that complexity that is just, I've been copying and pasting through like 400 libraries and we're just flushing it out and Carter's doing an amazing job going through and updating all our libraries. So we have a blog post of this and more and then the other thing we have is if you go to our December of 2019 blog post, you can see the features that we had asked Arduino to consider download stats for the Arduino community, tiny USB support and Arduino core, UFT bootloader support, Arduino library standards and automation. That's the stuff I'm working on now. Uniform transfer of structured data. Yeah, that's what I'm talking about. Support for Grove Quick Stemma and that was actually on the mailing list today. You're totally, if we did another post, I would actually ask for the same exact stuff. This is the tooling and the tool chain stuff and continuous integration and standard for library writers. Oh boy, that would be so great. So this is, the reason I'm putting this in the Python on hardware section is because we wanted to see something in Arduino but because it wasn't there, we were able to do it in Circuit Python and now we're putting it in Arduino. So there's lots of different ways to get to a destination. This is one of them. And that is the Python on hardware news this week. Thank you, Blinka. Okay, we're an open source hardware company because we're just talking about open source. One little programming note. October is open hardware month. I'll probably be doing a series of articles that will not have time to do an article a day, which I've tried to do in other months. When there was an open hardware month, I'll probably do a few articles. You could check out ohm.ashwa.org and there'll probably be some events and more and I'm gonna try to get some of the Oshawa folks on one of our show and tells us something. This is a good time to, if you have open hardware, register it with the open source hardware registry. We have a couple blog posts, certify it. This is a, it's a good thing to do in October. Okay, and then also, we have 2,537 guides for our product software and more later, what are the guides this week? Okay, we have a bunch of new guides. So, we've got a catnip update in our INA 219 guide. I know Pedro and Liz Clark wrote a wireless BLE gesture mouse project for last week, which is really cool. I think this is a really great stepping stone for if you wanna have like, HID or like BLE wireless data. We also have a guide for our 1.7 inch round rectangle display. Carter updated our Pi Zero headless quick start. And then you wanna, Yeah, wanna go to the next one? Yeah, yeah, yeah. We also wrote a guide specifically for MP3 playback, audio playback on the RP2040 with Circuit Python. It turns out that even though there's not a DSP in that Cortex M0, it is fast enough to decode. MP3 is up to like 64 kilobit per second, which is pretty cool. We showed how to do that with PWM output or with I2S output. Also got this week's cool project. You know, we watched Suicide Squad a month ago and we're like, I saw this spoiler alert, there's these staro things that fall on people's heads and they have an eye in the middle. And we're like, oh my God, we should totally make that with the Halloween because it's exactly the harder we have. No one paid her to do that this week. JP shows you how to make your own detachable USB cable with aviator connectors. And Dylan worked out with a very common request, how to communicate between two boards. You wanna send data back and forth, not wirelessly. Here's how to do it with UART and there's some, sorry, there's some great example code that you can use and adapt. This one is light sensor to NeoPixels, but of course it can be any kind of data back and forth between two microcontrollers. All right, let's do some factory footage. And it wouldn't be New York City factory footage unless you saw the Disney building time locks from across the street. If you've tuned in for a couple of years, you're gonna be able to see this building from demolished to a giant, I guess, mouse or something, I don't know. All right, 3D printing. Big golden ears. Yeah, and I think we're doing good on time. So I'm gonna play all the 3D printing videos back to back. This is the Bluetooth mouse, the star out face thing, and then the speed up of Captain America who got turned into a zombie. It's good we got both Marvel and DC universe for you. So whatever your interests are. Yeah, I don't think they'll be allowed to merge. I don't know if they would. I don't think they'll be allowed to. I'm sure there's plenty of podcasts. I'm sure Disney's trying to work it back. I know. All right. Hey, what's up, folks? In this project, we're making a BLE mouse with Adafruit's Feather Sense. This project uses an accelerometer to make mouse movements so you can wirelessly control your computer. As you move the device, your computer's cursor will follow your movements so you can tilt up or down and left and right to move the cursor. You can also use the onboard switch to send mouse clicks so you can navigate and click around. The Feather Sense NRI52840 has everything built in so it makes these type of projects really easy to put together. The proximity sensor is used for scrolling. Just cover up the sensor with your thumb and tilt up or down to scroll a web page. This makes it a fully capable mouse that you can program to wirelessly control any computer over BLE. All you need to build this project is the Feather Sense, a slide switch, and a small lipo battery. The code for this project was written in circuit Python by Liz Clark and uses the BLE and H&D libraries. Accelerometer data is converted into horizontal and vertical movements and the degrees of motion affect the speed. In the serial console, you can see data from the sensors so you can fine-tune the sensitivity. The Feather Sense shows up as a BLE device in connected computers with either macOS or Windows. The code is up on GitHub and features comments so you can modify and customize it to fit your project. So if you're looking to make a wireless H&D mouse, definitely check out Circuit Python for your next project. Thanks for watching and be sure you're subscribed for more DIY projects from Adafruit. Hey, what's up, folks? In this project, we're making a face mask inspired by Starro from the Suicide Squad. This mask is flexible and features blue and purples to look like those creepy starfish face huggers. The hollowing is the perfect board for this type of project. It's an easy way to get an animated eyeball with no coding skills required. The mask is 3D printed and flexible filament so it can wrap around your face. It's made from two separate pieces that are fastened together with machine screws. The flap on the back allows access to the built-in power switch so it's easy to turn on and off. All you need for this project is the hollowing, a lipo battery, and a convex lens. The mask is 3D printed in NinjaFlex. This filament features a shore hardness of 85A and it's both flexible and elastic. It's also 3D printed with some support material. These parts are stringy and need a bit of cleanup which is easy to do with a pair of flush snips. To color the parts you can airbrush both sides starting with some shades of purple. Airbrushing NinjaFlex is a bit better than acrylic paints because it won't crack when flexing. Then you can add some blues and blend them together to make some gradients. The lens is added to the center hole cutout and is held in place with the lip along the edge. The hollowing board is placed on top with the mounting holes lined up. Machine screws can then be fastened to the built-in standoffs for a nice and secure fit. The backside can then be added with the flap lined up with a built-in switch. Machine screws are added to each of the mounting tabs with the two sides held together. You can paint over the screws with acrylic paints so they blend in with the rest of the mask. The tips of the mask are held in place overnight so it can retain that curved shape. You can add an extension cable for a bigger battery and hide it in your pocket so it's not directly over your face. You can add a strap or a piece of ninja flex to act as a string to keep the mask fitted over your face. We hope this inspires you to try out some ninja flex and check out the Adafruit hollowing for your next project. Thanks for watching and be sure you're subscribed for more DIY projects from Adafruit. All right, don't forget every single Wednesday at 11 you can watch 3D Hangouts with no Pedro. We can learn how to make all this stuff and more. Ready Lady for the great search? You have some stuff going on here. Sorry, not the great search. IMPI. IMPI. Here we go. All right, this week's IMPI is from Bud Industries. Bud. Is that I think our first one from Bud? They're our best buds. This is an American company that specializes in enclosures. They're really good at outdoor enclosures and today we're featuring one of their enclosures I think they did a really nice job on. It's a nice box. Yes, this is a nice box. So let's check this out. Okay, I'm going to go to the first. Yes, sorry. I'm going to read off the part number. This is the AIO 11111 or the 11112. So that's four ones and one or two from Bud Industries. They're very similar. And it's kind of neat because I've seen enclosures that are latched outdoor enclosures. Yes, I've seen outdoor enclosures that have clear funds. Yes, but I have not yet seen an enclosure that has both. This enclosure, it's meant for, you know, wall mounting, electronic projects and what's really neat about it. And I think I think let's go back to the front because I to show this, I kind of need to Okay, so this is the enclosure. This is one of the biggest IMPIs. So this is one door that you can open and it's clear. And then there's a second door which is latched. And then I can open this. I just be careful not to clonk you or me. So there's basically a window here and a window there. And then there's this plate which you can mount onto the back here to protect the inner area from the outer area. Like there's basically two sections of this enclosure. And so you can keep some parts safe and secure on the inside while having this door. Yeah, that second photo doesn't pretty well. The second, the clear door can open up while keeping stuff on the inside safe. So why is this cool? Well obviously, you know, usually you have a clear, you have a clear front if you want to have LEDs or TFTs or gauges or whatever. But with this enclosure, there's the door lets you open up also like press buttons or reset it without opening up the big part of the enclosure which could get dust or water into it because both doors are gasketed and it's IP 66. Okay, so let's go to number two. Yeah, so you have some measurements. Yeah, so check out the data sheet because it's really nice. They did a good job giving you all the dimensions you could possibly need. The mounting bosses, the height, the depth, like you know, everything is quite nice. They've got it in DXF format as well as PDF but like I'm just showing two images from the data sheet but there's a ton inside. There's mounting bosses with tons of holes for mounting internal circuitry or mechanical panels as a substrate. One of the really nice things about these enclosures and I've seen a lot of enclosures since I really stuck out at me is that the gasketing is, it's not like a bead ring. Sometimes you get O-rings or like little beads and they work okay but this is actually kind of an extruded, thick plastic rubber gasket and both doors are gasketed fully so that's what gives it the IP 66 rating which means that it is fully dust proof and it's waterproof, you know, to the extent that you can have jets coming at it and it'll be protected from water jetting and obviously if you cut holes you'll have to weatherproof those holes. I will mention that even though it's IP 66 rated the material it's made out of ABS plastic and it's not UV treated so it's not meant for outdoor in the sun exposure because it'll slowly crack the ABS plastic. You could put it outside but just make sure it's not exposed to UV light which is hard to do if it's outside because you know outside their sun but if it is indoors it's going to be well protected against any sort of dust or oil or water that you might have in your factory or around your robot or around your maker project or maybe it's like a home automation center that would be something really good to make with it. There's also some cool accessories if you want that inner plate you want to mount stuff to it you could actually get plates at the top I show the images at the bottom are the digit key part numbers and they have them in stock for a plastic plate and a metal plate that even has like drill holes in it so you can like easily mount you know more complicated electronics or robotics components into the enclosure and then of course the front plate it has that little insert plate I showed you it's also ABS plastic so it's really easy to machine or mill and I'll also show you the video about customization but I think like if you want to make a project that has like you know a big power electronics thing or monitoring thing or IoT thing and you want like that you know that Raspberry Pi to be safe and then you want the display and the buttons and the gauges separately available this kind of gives you the best of both worlds you don't have to pick and choose and it's in stock available on digit key here's two types again there's the one one one one and there's the one one one two I think the one one one one is seven and a half inches deep and the one one one two is nine and a half inches deep that's the depth from the wall but check the specifications to make sure as you saw it's a pretty big box but like it'll fit anything in it for sure definitely like a large display and then of course use cable glands if you want to maintain the IP66 rating for all the cables that are coming out of it yeah someone in the shot said the inner panel is great for mounting screens button selector switches and so on this is exactly what it's for and I love that you could open up you know you don't have to expose all the delicate innards you can have a semi protected area and then like the very you know delicate electronics behind it because every time you're opening that panel to reset the button or to adjust something or to turn on or off you don't want to expose all of your wiring to whatever dust a light or oil or humidity that you've got in your house and here's a video about it here's how to customize the box which is a service that digikey and bud offer together so contact a digikey sales rep if you want to have like custom holes drilled in upon as your design work on your great new project is wrapping up you realize that you need an enclosure in the past when time was tight you would have to purchase a standard box and then send it out to either a local job shop or the shop in the back of your facility to have the holes and slots put in for such things as connectors power cords readouts or whatever else you might need this was either expensive or pulled your employees away from other jobs that they could be doing but you really didn't have a choice because getting a custom product out of a typical enclosure manufacturer was harder than getting a bill through congress today you have a great alternative bud industries has pioneered rapid turnaround for modifications to its broad line of standard enclosures here are the quick steps to making it happen first use bud's product selector to choose the product that best matches your needs then check with bud or your local distributor to be sure it's in stock once you've found the right enclosure send us a drawing with required modifications to the box of course cad or 3d models are great but bud can also work with as little as a sketch when we have received your information we'll quickly get a quote out to you as soon as you place your order bud will rapidly create a detailed drawing for you to approve once you confirm the drawings bud will complete your customized order in six days for the first run or five days for repeat orders this is two to three times faster than most enclosure suppliers and covers holes slots or other cutouts in the enclosure note that there's no premium charge for this service it's just buds everyday great service all right let's uh do the code deductive user to lose it next hour or so and uh let's do new products all right let's jump right in okay we got a bunch of stuff we'll get some of the the ones that are just like kind of repetitive out of the way really fast so we got more keyboard stuff okay so these are keyboard plates that you would use you have an enclosure you have a pcb and you want to stabilize the keys so they don't kind of wiggle back and forth especially if you're using socketed mx pcb's which people love this is a 60 gh 60 very standard common layout you see it fits into any of our 60 keyboard shells we have quite a few of them we have this in a couple colors we have silver we have a gorgeous uh blink of purple here's another angle shot and then we also have black they're all the same thing but i just wanted to carry them a couple different colors in addition to these mechanical stability plates we have this kind of this foam insert sheet so this is an insert that people are like okay i want stability but i also want a little bit of softness they don't want their keyboard to rattle so it's a little thin piece of die cut foam that you can put underneath the pcb or between the pcb and um so yeah under the pcb and the enclosure and it just gives you a it's a little bit of padding like one millimeter thick padding and then of course all these are for 60 percent keyboard so if you're making a keyboard it's kind of what we recommend you start with and this is just makes your build a little bit nicer yeah all right then we got a bunch of these so we we have custom keycaps now but then we also have a way for you just to carry around the custom keycap with you so let's say you really like your mechanical keyboard but you know you got to go out once in a while so you can bring one of the keys with you yeah well i do think these are cool little fidget toys and also if you want to show off your custom key so of course we have the animation it doesn't come with a keycap we sell tons of cool keycaps but we're showing them of course with adafruit does not come with a human hand not come with a really nice nail job out there who's gonna ask but we did get them in a couple different colors red green blue and white which we thought were the most fun and then let's go to the overhead real fast I can show them off because I want to show them in 3D yeah so I got all these and we just put more of the github ones in stock that's true do you want those github yeah and this is what it looks like without it on there but let's go to the overhead yeah so these are all very similar but again different colors so I can press them all at once and they look great each one of them comes with a key switch already installed it's a blue clicky and on the bottom is a cr1220 coin cell battery this mechanically connects like the led to the battery so it'll last like seven or eight years of use and then of course you can always use a little screwdriver or something wedge the key out replace the battery if you like you even can replace the led if you if you want to but it's just a fun little key chain and we wanted to do a little bit of a giveaway once in a while where people can get one of our key caps and also light it up I don't know I just think these are adorable cute little gift and a fun fidget toy strain gauges next up these are strain gauges that we will not be stocking again we stock 75 millimeter strain gauges and we got a shipment of 80 millimeter and we didn't want to throw them out because they're they're still very useful but that said after we sell through these 80 millimeter long ones we will not stock them again they're a little bit cheaper than the 75 millimeter ones because we're just gonna sell them out and if you're if you're doing a project you don't need hundreds and hundreds of these you only need like five to ten for your project and you won't need them again and you're okay with the slightly longer size they work great I think we've got five and ten kilogram versions yeah the other ones and then solenoid adorable little solenoid this one it's a little friend it's a six volt solenoid a lot of people have been asking for us to please carry more low voltage solenoids because 12 volts 24 volts is the standard but this little mini lock solenoid which is quite popular we have a 12 volt we've asked for it in six volts now the deal is that if you're going to look at it as a lower voltage you're going to have to give it a lot more correct because it still needs the same amount of power so it is a 600 milliamp draw device so just be aware if you're running it off a battery or even off of usb that's kind of the like the limit of what usb will give you 500 milliamps or so that said it's pretty easy it's a pull type solenoid so when it's unpowered the little widget thing the triangle is sticking out when you give it six volt power the triangle pulls in and you can open the box or unlatch or unlock something these are quite popular a little push solenoids or push pull solenoids for use in projects like geocaching or if you want to have like a magical box that opens when somebody like scans their fingerprint or their eye or you know machine learning project has mounting holes very easy to use and like I said you can run off a six volts you can might be even get away with five volts just make sure again you need 600 milliamps next step okay we saw this being used in a bunch of like DIY keyboard projects and I'm going to stock it I will say yes it is not up to the USB-C PD spec but it does work and a lot of people were using them and so we have a breakout that if you really want something that fulfills the specification and has the right resistors this will work fine on most computers every computer I try it on works it may not work on a power supply that requires power delivery resistors it's kind of a hacky thing it's a little bit punk I like to carry stuff that's a little bit punk sometimes that is right this is one of those things some guy emailed us and said that we flagrantly disregarded the USB-C spec and we're polluting the USB-C ecosystem and out of it so there's yeah so we get emails from guys often and they say things like your code is spewing your code is spewing all over the place because we have like so much open source code and I've never in my entire life heard or seen emails to dudes from dudes this is because you made this LeMore and I think it's cool I didn't think this was carrying it I think it's cool okay well I think I think it's cool too it's a little punk rock it's a little different again yeah you care about the pd spec anyways get the version we make with the with the resistors on you get the products cost money but that rant was free that's right okay these are we had some tower lights last week and I saw these from the same supplier and it's kind of weird it's a hemisphere alarm light inside is red yellow green LEDs and you can see you can kind of turn them on and off is yellow and then green and then red so it's meant for alarming but it's like a hemispherical light and there's two versions okay so you actually go back to the back to the moment I guess I don't know I don't know go on yeah okay so this version see I got those holes on the side those holes are for a buzzer so this version has a buzzer and it plugs into usb so one of the nice things about these alarm lights is that they show up as a serial port you just send them commands through python or shell script or whatever you like minicom and they'll turn on the LEDs and they'll turn on the buzzer so you don't need to do any wiring the code is very very simple there's no 12 volt power supply it's plug and go and you've got this like alarm system a lot of people like to do a little like oh when I get email it blinks or if somebody you know is you know went to my website it blinks or buzzes or who knows what this will do the job admirably it's quite easy to use if you want to use it through a website you can even use it with web serial because again it just shows up as a comport we also have a version that looks very similar and it has the same code the same kind of design except this one is weatherproof it doesn't have an ip waiting but I'm going to guess it's something like ip 64 it's going to be dust proof and like I wouldn't dunk it under water but you could probably splash it with some water and it'll be fine it is sealed and it doesn't have a buzzer that's the trade-off if had a buzzer it had holes in it it wouldn't be weatherproof but this one's probably better for you know more robotics or exposed stuff you could probably have it outdoors as long as it isn't like directly in the rain and you can use it for alarming or notifying somebody you know with light not with sound the other one with sound so two different versions don't mix them up you either get a buzzer or you get the weatherproofness next up we got an update to our 2.9 inch e-ink flexible display if you do e-ink you know that e-ink displays are constantly coming out with new chipsets they're pretty much the same shape, design, pin out whatever but the driver it changes the drivers are getting discontinued and replaced like every three months it seems anyways it's time for the 2.9 inch e-ink display I think it was using the ilio373 it is now using the uc8151d we have code in circuit python python and arduino no matter what so no worries it's a flexible display I think it's really cool people are sending us some flexible displays today and I'm like you can get this e-ink display and it has like 300 by 150 pixels and it works great and it's flexible check it out and it works with all of our e-ink driver adapter boards can have the standard pin out next up okay next up these are kind of cool we actually saw these I think what Naomi had been on her yeah and I immediately started making glowing lego like bricks and posted it up and cool was told I didn't use the right capitalization yeah it's a lego please can I have do you know so you had a couple different ones here and this is magical when you see it so we're just going to go to the demos okay almost almost right away I have to wire up the demo you didn't wire up the demo I did but it said then I had to move it because the thing was so large all right then I'm just going to play this video until okay okay okay I have a video on our youtube channel what that's to do why don't you play it no I can't I'm doing this show right now yeah I can't I can't go to youtube let me install for time here is this one look the show is live yeah okay so let's go to the overhead so if you do have lego like bricks you can embed these inside of it and make a lot of cool stuff and that's what I did that's what I did and they should do that too and they should also stop bugging me about the lego capitalization the way that do you want to put these in like a lego cop car because then it could be a lego cop yeah I do okay all right so here's how it works this is a inductive coil driver so this driver you give it this one in particular is 5 volts and here's an inductive coil and we have inductive coil chargers and like key chargers you know they they use inductive the inductive properties where the code is inductive this is one side of the coil and then normally on a transformer you have another coil there's a magnetic field coming out of here it couples to the other coil passing over transmitting over electromagnetic energy into the other coil and so if you have that coil for example as a inductor soldered onto an led you'll see that it glows when it's in the vicinity now like any coil inductive transfer system you want the coils to be coplanar what does that mean is that see how this coil is like curling around this way you want it to curl in the same plane so it works best when it's pointing in the same you know it's within the same circular plane if I tilt this over to the side it gets dimmer and then if I have it on its side it actually turns off because it the electromagnetic current has to go in the same plane so the only thing is just watch out for that if you're like it doesn't work no it's working you just have to have them pointing up that said it is really cool these are used often for like models we see again like Lego or 3D printing things where you don't want to wire up an led or you can't because you have to embed it in something so thin and small you don't want a battery pack but you can have a coil underneath and then you know it lights it up from below I also think it could be cool for arts and crafts you know if you're sewing something or you have a wearable and you don't again you want to have something that's movable or adjustable or it doesn't have wires coming into it and then you have it powered from this external coil you get one of the coils you just power it with five volts you get a bunch of leds in different colors you get red, yellow, green, blue two of each of these little coils and they look cool and they're nifty we're gonna do some 3D printing projects with these so that's the five volt version and then if you're like you know the one thing about this is it only works I think you know a couple looks like you know one, two, three inches away from the coil and of course you have to kind of be inside of the coil for it to work best maybe you're like I want something a little bit bigger I want something to work a little bit more distant you can upgrade to the larger coil now the larger coil is large mega coil all right why are you doing that I'm gonna finish of this so that's a small coil I'm gonna go back all right sorry there's so many coils okay so this is the big coil this is small coil big coil small coil big coil you'll notice it's very big it's a bigger coil that means it can transmit more electromagnetic energy but the trade-off is you have to power it with a lot more voltage and current so instead of five volts you need 24 volts which is a slightly unusual amount of voltage we do have a 24 volt power supply just be aware it's kind of people don't often have a 24 volt power supply the bigger coil is fun because you can put the leds further away in the middle and you could do a lot more fun stuff with it yes people are talking about escape room projects and there's a lot of things you could do yeah I mean this is cool so what's nice about this is of course the coil is bigger so you can be much farther you can be about six inches away in that you're like well the coil is four times larger why isn't four times more powerful it's because the inductance transferance is one over r squared or something one of r cubed so it's not linear but that said I'm going to grab a white one because it shows up pretty well you know it works much much further away than the other one if you remember the other coil it was like two inches this one is like six to eight inches away of course it depends you know what else you have and if it's like perfectly aligned with the plane of the coil but this one is a little bit because there's so much more power it's a little bit more flexible even if you have it on its side it still even lights up even if it's not co-planar because there's just so much power coming out of this coil so there's the two coils the LEDs themselves are the same but again one coil big one coil small which do you need which do you want depends on how far away you want the LEDs to work and how much power you're willing to dump into the system all right and next up start of the show tonight besides you Lady Eater the community our customers everyone in the chat and the the OctoCat keycap and our team is the LED glasses panel okay this is the name of the product LED glasses I don't have a better name for yet because this is what it is I've always wanted to have LEDs on our face we have a bunch of Neopixel projects that we've posted but they'll always like take some rings and you sort them to a QT pie and then you know whatever and I was like well what if we made it really easy to do LED glasses Facebook and Ray-Ban play their games and we're gonna play ours this is ours this is not going to post to Instagram for you but it will look hella cool so here's the thing each board is it's an I squared C peripheral there's a stem and QT connector and either side there's no microcontroller instead there's a little driver chip in the very center kind of in the center of the temple and that controls 116 RGB LEDs that are arranged in a kind of interesting way so paint your dragon came up with a interesting layout instead of just having it be just like straight up grid there's two circles and then there's a grid I think it's five by 16 overlaid on those circles and so you can have like circular designs or you can have linear text scrolling type designs where you can choose you can have both and I thought that was kind of neat because I really like the circular eye design but I also wanted to be able to scroll text so this demo shows you know it's it's there's a lot of bright light on it so it doesn't look very bright believe me it's it's plenty bright but you can have text going by and stuff going around the eyes each circuit board you can have one of four different silk screen there's bug there is cat there is wolf and there is dragon so philby did the silk screen for these and here's the deal you don't know which one you're going to get and we can't control which one you're going to get they are totally random in their box and we don't know what you're going to get we want to try something a little where it's like a little random a little chancey but all four really beautiful designs so no matter which one you may get they're going to look cool and of course the electronics works the same all right so I thought I would show you got these well let me show I want to show them on the overhead or do you want to wear them what do you want to do I thought I'd wear to start all right lots of live demos today okay so let's go to the front camera so I've mounted them on to I got these they're for lack of a better word they're like fashion glasses I guess these are popular with with kpop stars so this is me and what's cool is you know these glasses you can wear over them so you can see there's a grid so see the grid is like a rainbow grid and then there's two circles and so that's kind of the thing I think is neat is you can you can choose I'm switching between the two I'm looking very cyberpunk but whether you want this style or the other style or both you can have text you can have swirly designs all sorts of good stuff so then I thought let's go to the to the overhead and I'll show so yeah this is them with the leds nice and bright and just showing the two designs so again this is I squared c only you would connect this to your mic controller whether it's wi-fi or bluetooth or it's like a cutie pie or whatever and then you can run our circuit python or Arduino library code to control what's on it the reason we didn't put the mic controller on here is is first off we wanted to make it really simple so people could adapt and adjust it however they want and second because usually you would have like a feather or something stuck to the side like here and then a little cable to connect with it and then of course if you want to add it's I squared c so I squared c coming in this way and then you can have sensors accelerometers light you know detectors what have you on the other side so you can make your own like like you said like Facebook glasses but way better way more colorful not from Ray-Ban yeah and that is new products that's new products okay uh folks have some questions lined up in the chat go do that over on discordatorfruit.it slash discord join our 30 000 of us let's do top secret and then we'll bounce to the questions and then we'll bounce bounce for sure so from the vault I got a lot in the vault yeah so let's first start with a video that has something to do with these glasses because I think that's the easiest thing doing you can get an idea of what we were doing earlier in the week early data what is this this is my desk full of rainbows I'm doing two things here one is maybe a little demo here for the led glasses so you can see tech scrolling and then also the led rings glowing so that's some Arduino test code working out here and then over here I've got my new seesaw dev board based on the 80 tiny 817 so this is connected to a metro mini over I squared C so this is the controller and this is sending neopixel commands over I squared C to here and then I've got to ring here just to demo it and then I got on the oscilloscope checking out the signals making sure they're nice and clean looking good so this is going to be the replacement for the samdi 09 chipset early hard to get that chip but this one is a little bit more available less expensive and also three or five volt capable so also together kind of a nice little upgrade to our seesaw designs okay and you have some breakouts okay this one this is a fortune sorry eight channel ADC that runs over I squared C so I'm making a stomach QT breakout for it except I'm also again redesigning the CP 2104 USB serial adapter board to the CP 2102 I was playing USB C while we're at it this is a kind of a new sensor from ST it's a like eight by eight multi zone time of flight sensor that VL 53L5 CX so middle breakout all right that's not secret yeah coming soon yeah all right we're going to bounce for it just questions yeah let's go yeah we're going to do questions while you have those glasses on yes it's important well for the folks who are like well does the light go into your eyes well no and you can see through this the back is completely off so the light is only pointing out at other people they have to deal with you and of course I can see just fine I mean I can see I can see Phil here okay I can see you well I can't see you because your camera's not on I'm going to just start going at these right now well Adafrit ever sell wireless LEDs without the inductor also what's the max size of end inductor I think it's like a micro Henry we may stock the LEDs I want to start with a like starter kits to get going but if they're popular yeah I'll carry a little LED kits okay do you know the efficiency though not efficient okay do not do not use these for efficiency okay you already answered the light question about the glasses yes question if open source business closes so you do you sometimes pick up their designs and make them no we haven't so far not because we we've seen that and wanted to do it so every single time we've made a design that someone else has made we've contact and work with them we even pay royalties to folks we don't need to it's open source but we've always done that so I guess I guess maybe one day in the future if there was an open source design and the company went out of the business there was no way to get a hold of the folks yeah I guess we could but I'd have to say but by the way if you are wondering can you do that the answer is yes of course of course technically you can't do that we've never done that we're held to a different standard than everyone else with everything so we wouldn't just make an open source design without trying to contact the creator just to let them know what we're doing anyways yeah okay um does the the coil LEDs have built in resistors um no I don't think they do I think that the coil just they're just not the the voltage that's passed on the other side it's only three volts max anyways or something so you don't have to worry about that I've not seen them burn out I put them you know you can put them as close as you want okay um someone want to know could well I'll just I'll change the question a little bit could we make a pack of four if someone wanted to buy all four so they got each different one we just not right now we're we're we're we're doing this and we're going to experiment with it and um all four designs are cool but um we're going to just get a random one on each order if you buy four you might get four of the same one yeah it's a little full yeah um is the rp2040 now our go-to chip it's one of our go-to chips we've made a couple designs with it it's wonderful the back row pad used the rp2040 and it was awesome yeah uh next up been trying to make an animatronic uh on an arduino uno compatible with the interfruit 16 channel servo pwm shield how would i do a sweep of 180 degrees and 60 degrees afterwards check out the servo library for arduino and there's actually a sweep example and you can just set the angle you want and you can do you know little sweeps or just set the angle and let it move as fast as it can and that's how you would have it move back and forth you would you would have you'd set the angle and then weight and then set the angle to something else uh do you know the power draw of the glasses at max if you're to put a maximum brightness i don't know but probably 50 milliamps or something it's not as bright as you'd think because it's multiplexed so it's not driving all the leds at once actually driving nine leds at once okay and next up oh this is uh is hackaday future still in limbo i don't know um for uh the interview that i did so seamen's bought hackaday i have nothing to do at the sale i started the hackaday site 16 years ago but it went to uh weblogs Inc and then afterwards um supply frame and now supply frame's owned by seamen's so i don't i don't know did that sale complete i don't know i mean there's regulators and all sorts of stuff i don't know it's a good question yeah um and we probably won't know seamen's a publicly held company so eventually we'll be able to probably see something in their annual reports and more um but as far as the what's the what is the future hold i haven't seen any difference in the um quality or quantity or the coverage and i think they're doing remote icon yeah and so so far so good i would like to continue to uh hope for the best and then i guess i'll be disappointed later if something happens but i'm just gonna try to yeah i'm gonna try to assume the best and the and it and this is an important thing for people and they're gonna keep doing a good job at it next up if only the macro pad what's the best time to ask questions you're gonna ask an engineer oh yeah at the end during during yeah during the question during the question time yeah could we try to get through them really fast and then some people like to uh not after yeah then some people like to just go through this do you know the frequency of the inductive coil alternate no i don't know and under the details that killer hurts maybe it's not audible okay uh what are the specs of the new time of flight sensor check the sd data sheet i do not know okay and is there any chance we would make our own silicone so we could but we're not going to because other people who are really into that are going to do that and it'll be easier for and they're good at it yeah and we can make the suggestions so i think one of the new best things that happened was the raspberry pi folks made a chip and we're able to give them information feedback and more and i think that's going to be the best way for the community to get all the features they want if someone said like what chip do you want to be like well like a wrist five that has usb like that yeah we asked them and some ram yeah but if i was doing silicon i wouldn't do hardware it's very hard to do both yeah and like i said i'm not that interested in to be honest we do not own radioshack yet but we do we did an interview with the new owner of radioshack i have a 2.7 inch sharp memory display that i'd like to be able to see at night any recommendations on what how to light it just use some leds i think that'll work great
