 Life from New York, it's SS engineer. Hey everybody, it's me Lady Aida with me Mr. Lady Aida. We're here at the Adafruit factory in downtown Manhattan. It's where we do all our testing and coding and manufacturing and shipping. All the stuff that you love is made right here in downtown Manhattan with me Mr. Lady Aida. We live together which is why we don't have masks on and normally we have masks on in the office. I'll talk about some updates with COVID related news and more. Still doing it. Yeah, pretty soon we're not gonna have to. I hope so. Let's go get right into it then. What's on tonight's show? On tonight's show the code is magnetic. 10% off all things in Adafruit store that's in stock all the way up to 1.59 pm. Use it. 10% off in Adafruit store. We have a bunch of live shows. We're going to talk about those including show and tell. We're going to do some time travel. We got a bunch of stuff. We've been posting a lot of retro things and more. Help wanted jobs from the Adafruit jobs board. We've got 3D printing. We've got new products. We've got top secret. We answer your questions. We do that on discord adafruit.it slash discord. Join all 32,000 of us. Hang out all the time. All that and more on you guessed it. Ask an engineer. All right, so the code is magnetic. Don't forget. Use that. Put stuff in your cart and then before you check out use that. Let me do just a quick bit of news. So for those of y'all who know us, the first two weeks of the year was tough. Everyone came back from holiday. Various forms of getting tested. Folks getting positive results for COVID. And then good news. No symptoms. Adafruit team happens to be fully vaccinated, boosted, ready to go. But you know there are family members or friends or whatever. Lots of folks are testing positive and the numbers went up, up, up, up, up, but as of now they're going down, down, down, down, down, down. So we're almost back to single digit positivity rates. If you look at these charts, it went up as fast as it went down. What's that chart? This is I think hospitalizations. And then I think this is people I see you. In the ICU. So it's going down really fast. That's the good news. And then we have rapid tests for our team. We have a little machine that we got. It arrived and we were doing testing. Lady Aida has no COVID. I have no COVID. And other people here have no COVID. So that's good. And then master going out, I guess, to millions of people. And then also folks can go online and order free tests. So looks like we're through the worst of it. We'll see how it goes. But we're almost at a finish line. But this victory has been snatched from us before. So that's a little bit of an update. We're still grinding away. Thank you, everyone, for all your orders and support. We're dealing with multiple things from supply chain, from park shortages to it just being very difficult to live your life when this is going on. So we do appreciate the support. And thank you very much. Speaking of, don't pay full price. Use the code, you get free stuff. That's right. We are still keeping free stuff. We're going to get back to having more cool freebies. But it's really hard to get parts right now. And so what's interesting is that it's even that's been almost two years, it's still quite hard to get some things that haven't gotten easier. But we still have some freebies, $99 or more, you get a free half sized perma proto board. We love using these all the time for our projects. They're the size of a solderless breadboard, but with gold pads so you can solder your project and make it permanent. $149 or more, we still have a selection of STEMI QT sensors and boards. You get a free one with every order. You get a different one each time. If you make an account, we'll make sure that we don't send you the same one twice. And then $299 or more, you get free UPS ground shipping in the continental United States. We're out of circuit playground express, we had some and then they instantly sold out, which is good. They're going to students in schools. We're going to have another shipment and we'll get back to that having that freebie real soon now. Okay. We do a live series of shows every single week. We just finished up show and tell. It's every Wednesday at 7 30 p.m. Eastern time. We had a bunch of folks on the show and tell. I think this week, lots of music stuff, and I like the clock that Jepler did, and then Tim, funny guy, did this really neat cat screensaver thing that you wanted to do. Yes. I love old screensavers. And we did flank toasters a while ago, but then I remembered Nico, which is a little cat that would run around on my Mac classic, my SE 30, I think I had it on. And I really wanted to relive those days. And he did a great job taking the pixel art and turning it into a little animation in Circuit Python. On Sundays, we do a desk of LaData. We have two parts. The first part, we talk about what's on the desk. What was this week's desk of LaData? Oh, goodness. What was it? Much more floppy stuff. I designed a new Feather ESP32 with a new Pico module. I did a five and a quarter inch floppy interfacing and reading, adding support for 360K floppies. So the floppy stuff is going. It's not going to be super fast, but floppies are very fast. And also a couple of QT Pie boards I designed. I showed those off as well. All right. And then we do the great search. This has been really useful, especially over the last year or so. This is where LaData uses all of her powers of engineering to help you find things on digikey.com. What was a great search? This, I do remember. This one, it was the, I was looking for the, for a very small stereo headphone amp that doesn't require capacitors on the output because I need to fit into very tiny space and also to be in stock. And so I found a good one from Maxim and showed how I spec the part and why I picked it. And also some things to watch out for when looking for these headphone amps. Okay. And then we do JP's product pick every Tuesday. And that is a live show that's from the product page. And the discounts automatically applied. So you can just see what JP is talking about. Add it to your cart and you don't have to do nothing else. And it's just for the live show. That's the only time we do it. And it's a super good deal. And that's why we can only do it for a little bit of time. So here's the highlight from this week. And don't forget it's every Tuesday. It's the KB2040 keyboard. This is the board you've been looking for. If you've been wanting to do custom keyboard kits. This is the Gherkin. Just the smallest of the smallest usable keyboards. I realized last night and then Lady Aida texted me the exact same idea, which is this is now the world's ultimate Wordle keyboard. If you know the game Wordle, all we need is alphabetical. So I won't type any answers in here because I don't want to ruin this is today's game. But I'll show you that this is just a working keyboard. I can even try to press enter and it'll say that's not in the word list because that's not a word. And I'll delete here. Pull this little bottom plate. This one's made all of PCB of our four materials. So we have a key plate on top to hold the key steady of the PCB itself. And then we have our KB2040. There it is. It's the KB2040 keyboard. All right. And then tomorrow is JP's workshop. And on JP's workshop, we have a special segment, the circuit Python Parsec. Take it away JP. For the circuit Python Parsec today, I wanted to show you how simple it is to set up capacitive touch sense inside of circuit Python. So this is an example where I have a little cutie pie here. And I'm going to use one of its pins as a capacitive touch pin, which means I can touch it or get really, really close to it without even touching it. And it'll sense the difference in the capacitive storage potential of me and effectively close the circuit for me or touch, touch it to create some sort of an effect inside of the code. So in this example, I just have one pin on here, the RX pin. And when I can, when I touch it, you can see it's acting like a button. I just have it turning on a bunch of these LEDs here. I've got a funky, broken neopixel ring here. So ignore these busted ones over here. But that is just the same as any kind of button or switch that you could close, except it doesn't require an additional mechanical part. This is also really effective for when you want to cover something because you don't actually have to make contact with it. So you can use a piece of paper or fabric or something like that and still be able to touch something. So let's take a look at how this works. What's happening in code? I'm importing the board for pin definitions importing time so I can put a little delay in importing the touch IO library and I'm importing neopixel. Then I set up a variable called touch pin, which equals touch IO touch in and then the board dot RX pin or whatever pin you're using. Then I have a little bit of neopixel setup and then it's just so simple inside of the main loop of the program. I just simply check to see if touch pin value is true. If it is true, then the things inside of this happen. LEDs get filled red. I print the word touch and then I have a little sort of debounce pause there. Otherwise, it lifts the the pins back up to black. And so that's how easy it is to set up a capacitive touch pin inside of circuit python. And that is your circuit python parsec. Okay, and then Friday deep dive with Scott where you'll learn all about the innards of circuit python. And I can buy once in a while and more. Yeah. Time travel. Let's look around the world of makers, hackers, artists, engineers, news, and we have special lookbacks at Adafruit retro stuff and more this week. So time travel this week. First up, we have to do the reminder. Adabox will be shipping winter edition. That's what we're doing to make sure we can get all the parts that we need. So yeah, it's tough. We'll get it. We'll get it. We'll get it. We've shipped every single Adabox, even even during the shutdown, we were able to get an Adabox out. So thank you for your patience, but there's not a lot of Adabox is left. We only have so many slots. So winter edition will be shipping February, March, probably March. And go to adabox.com now. I think there's like five openings left out of the thousands. So we've actually, okay, I'm going to interrupt you. I'm sorry, but we, Phil and I over the last few weekends, we planned out this year, this 2022 Adabox. Oh yeah, we have all the Adabox planned. It's going to be amazing. Like we picked four like amazing. I mean, they're going to freak out. You're going to freak out. So you want to like get in because once, if you get in, you'll get them going forward. But if you don't get in, there's no guarantee that, you know, we don't kick people out, but you won't be able to get in if there's no slots. So it's worth it. Believe me, you're going to love the next four boxes. They're going to be, and they work together, but you don't need to use them. The thing that's in each one of these, they're going to sell out so fast in our store, which if it's a product that you won't be able to get it. So adabox.com, you should do it. We are securing the components. Yeah. Bit of a reminder coming up pretty soon in February, Lady Aida is going to do a special chat with Tom's hardware. And this is going to be the pie cast celebrating 10 years of Raspberry Pi, new episodes as Lady Aida, Evan Upton, and more. You're going to be on February 15th, Lady Aida and Paul Beach of Pimerone. You're going to be talking about all the things Raspberry Pi related more with our friends from Pimerone. Yes. You're going to hear some good stories from me and from Paul Beach. I'm going to talk about why we decided to Raspberry Pi and the moment that it happened and Phil was there at the moment and it's crystal clear. I know the block and I know this, the piece of sidewalk we were standing on. There was the fish market right next to it. I remember exactly when I turned to Phil and said, this Raspberry Pi thing, we got to do this. And why, but also like why, the story behind why. There's a gut reaction, but there's also a lot behind it. Raspberry Pi is really interesting. We also had to postpone another product we were doing. So we were about to release a bunch of wearable stuff and we said, we can't do both. So we decided, let's delay some of the wearable things and let's do some Raspberry Pi stuff. And it all worked out because you make it sound so good. But meanwhile I was just like, I'm like, I'm freaking out again. Do both. And you're just like, just do this one and then we'll do the other one. I'm like, I can do that. Yeah, we're lucky. We plan our freakouts at different times. So generally speaking, I'm up at 5am and Lamar is going to bed at 5am. So our freakouts don't usually happen at the same time. Yes. Nocturnal and whatever the opposite of nocturnal is. If you ask us independently, we've never seen each other freak out. We just do it alone and crying into our pillows. I know, but at different times. Different times. Totally different. All right. So this photo was taken 15 years, nine months and one day ago. This is the entire net worth of Lady Aida, all of Aida fruit, all on a table. This is all she had. This is all she was. Not the lantern. I don't know what the lantern is there. That was a flashlight. But I don't remember needing it. I think we needed that because I think the bathroom light was broken. Yeah, you lived in like a crummy place with like 15 roommates and there was no power or light. I lived with 10 people in a warehouse and we had one bathroom. Yeah. Let me tell you, nothing changes you as a human like that. No dishwasher either. There was no dishwasher. So this was Lamora about to go to Maker Faire in 2006. Since I met Lamora, I've been documenting everything that she does. Here is the window screen and then here is what we had and she sold the kits at Maker Faire. There was folks on social media today who was like, oh my God, I have one of those kits. Oh my gosh. I was a customer. It still works. You know, and yeah, I still have it. Yeah, it's still programmed too. The tutorial will still work. If you have an apparel port. So that is a little glimpse back and I guess the thing I wanted to say is it seems like a long time ago, 15, 16 years, a lot of people want to grow their companies fast. It took us 15 years and here we are and here are all of you and we built something solid and sturdy and something that's getting us through some of the toughest times ever. So the hyper growth and fake it to you make it and just all these things that you see and people being terrible to each other, you don't have to do it that way. And I just wanted to show this picture of this table because that's the seed. That's my I care. That's everything. That's my initial kit offering. Yeah. And anyways, so speaking of retro stuff, we started a series of retro hardware photos right before COVID started. And then I had to press pause because we were only working on keeping our team safe. So we're finally getting these up and then more. So this is one of the Apple speakers. This is kind of rare. This is the Apple design black version. This is for my personal collection, the Eat-A-Food collection. And then the other things, you're going to like this. This we just took a photo of. This is a 1982 Pac-Man phone back when Pac-Man was everywhere and it just launched in the U.S. in 1980 ish and then like Pac-Man just took over. And of course, you know, after I got these photos, this is a touch tone telephone. It's not a cell phone. I had to make an animated gift. Yeah, there's a Garfield phone, there's a hamburger phone, but my phone is a little bit, you know, overdone. I think the Pac-Man phone is nice, especially like the coil on the cord. Oh, one thing. These aren't shot cups. These are full-size green cups. We still have these in all the plastic cups. You put your parts in an excellent system for making kits and you pour it into the bag. You can do five by five, 25 kits at a time. And that was that was my system. And then you could pour the cup contents into the silver bags. And the nice thing about that is because the cup is white, you can look and you can make sure you can, you know, sometimes a diode would get stuck. We had it down. And back in the day, kidding, shipping. That was it, two people. And here we are now, 130 plus in a factory in New York City. So anything's possible. And we've been playing the video game on the hard level. So I just wanted to, there's a lot of people starting businesses and they're like, it's been six months. How come it's taking so long? It's like, no man, you got to wait a little bit longer and it's worth it. It's worth it. Just be patient. Good things were ahead. Next up. So we've been doing a lot of retro floppy stuff. This is our little cute rabbit icon. We're adding more kind of like, I don't know, like tributes to like retro history. And since, since there was the Winnie the Pooh freedom event, where it goes out of copyright, we have some graphics in that style. And this is rabbit. We don't, I don't know what the name of the rabbit's going to be yet. And it's a floppy rabbit. I like this one. Yeah. It's like, Hey, like I'm just hanging on these discs. And then this one is like, Oh man, like add a little bit too much to drink. Yeah, a little bit too much carrot juice. But then we have, let's see, one, two, three, four, five, we have six videos all under one minute each. So we're going to play these back to back to back. And you can see our progress leading all the way up to you being able to get a five and a quarter disc showing up like a USB drive mass storage. I cooked my brain this weekend. I worked on it for like 12 hours. So hanging out to the last video, it's only five minutes from now. It is absolutely amazing because you can use this old floppy disc five and a quarter as a USB drive. Incredible. Okay. We're storing 360k of data. That is actually quite a lot. There's a lot you can do with 360k. None of the Python code that I write anyways is not that big. Yeah. Yeah. Okay. Early data. What is this? More progress on our reading MFM floppies in Arduino and circuit Python got my floppy disk drive and I've got it hooked up to my feather and four. And then in Arduino, Jephler did a poor quest to add real time MFM decodings that like not just reading the flux data, but actually decoding it into data data. This is assuming, of course, it's an MFM floppy, which it is. And then this is code that dumps each track. And so you can see over here why I put text files on this floppy disc because I can actually read it and make sure that I'm decoding it. And here's the trick. You can see at the end of this, it continues onto the next track. And so I know I'm like reading the interleaved tracks correctly. And so far it seems to be working. I can read all the track data one by one from this floppy disk in Arduino with live on the fly MFM decoding. Early data. What is this? This is even more floppy disk hacking this time. Still got it wired up to my feather and four, but I'm going to be doing more USB hacking here because the feather and four has native USB can act as a USB device, which means I can run a 10 USB mass storage in Arduino, access the floppy disk drive through the MFM decoding, and have it show up in Windows as a floppy disk drive. And so you can see all those text files I copied over before appeared. You can see I can access this file, which happens to be an interview with Mudge. Pretty cool. Thank you, Mudge, for doing an interview with Frack. And this is all in a PR that just got merged into the Adafruit floppy repo. So Arduino floppy disk greeting is working. Next up, I want to get writing working so I can like store stuff onto disk drives. But I think this is the power of teeny USB, like it's a native USB device, it can act as a floppy disk interface. And Windows is happy to read the data from it. Early data. What is this? Okay, more and more floppy. Still got my feather floppy wing. I've got my floppy drive with the disk get inside. What I'm doing now is before I had the Arduino supply block data 512 byte blocks to the operating system Windows, and that would interpret it with USB to like show up as a disk drive. What I'm doing now is interpreting the FAT file system on the Arduino. So when I open up the serial monitor, it can actually read the disk drive, parse out, you know, the MFM to byte tracks, and then open that as a FAT file system, and then I can read the file on the Arduino itself. So that means I can, you know, save and read files from an Arduino, which is good for, you know, storing files, maybe data logging, and a project that I want to work on, where I read data from a floppy in Arduino. Early data. What is this? Hey, well, I'm doing some more floppy hacking tonight, so cold out. And, you know, I've got that three and a half inch drive working, but I also got a five and a quarter drive that I'd like to hook up, and actually only have Commodore 64 disks right now. And Commodore 64 is an MFM format, and it's a different format. And so if I want to read these disk gets, I want to use a piece of software called Flux Engine. And Flux Engine is a very similar grease weasel. In fact, grease weasel compatibility mode, but it's written much more, more low level C, and it supports a lot more formats. I couldn't quite figure out that grease weasel supports Commodore 64. So what I'm doing is like slowly but surely figuring out how to get Flux Weasel to recognize, you know, this port and send data back and forth. I'm learning a lot about low level Windows 32 file system access and comports. But I'm making slow and steady progress. This is, I did find one single bus formatted five and a quarter floppy, and this is my five and a quarter drive clunk. It's wired up to my feather with my floppy feather wing running my grease weasel emulation mode. And what I got working was Flux Engine. So Flux Engine is another software that can read floppy disk drives with flux data and then parse it out. And I did get this working earlier and I just want to quickly show this is what was on it. This is the image that I'm, you know, opening up on my computer. So it's got all that now stuff that you're probably used to if you had a Windows computer running DOS back in the day. And this is Flux Engine. If you're interested in it, it's kind of a cool open source Flux Reader. And this is the pull request that hopefully I'll be able to get merged in soon. You spin me, baby, right round like a floppy disk. Okay, so I've got my five and a quarter floppy disks. Not a good singer, good engineer. Got my five and a quarter drive wired up to my feather. And I'm now running the mass storage demo for Tuna USB, which means that this is actually showing up as a 360k double density drive. I had to refactor a little bit here so you can tell it, hey, for the MFM decoding, you're expecting 360, but here's the good news. It just shows up as a drive. And if you're like, Hey, I want to know what's in this readme.txt, it's a mouse driver for, you know, an old IBM PC, but it shows up just like a disk drive. This is a good example of why you can't just use a USB floppy disk because there's no such thing as a 360k IBM USB floppy drive. But now there is. All right. So thanks for being part of this journey. We're still doing a lot more. I think this is the only open source way to do this. There's open source ways to, well, for the USB, having it mount to USB drive, I don't know that there's any other, I don't know that there's any open source five and a quarter inch compatible. There isn't. And then there's emulators. But you know, it's all kind of the same code. That's the thing. It's like I'm doing like the archiving, the writing, the reading, the emulation, you know, showing up the mass storage. It's all kind of like part of one big project. I do have a favor. If you all see people online saying like you could just get a USB drive from Amazon converter. It's not true. So you can't just get a USB drive from Amazon that you plug into any computer and it shows up. It's not possible. But, you know, way to go Amazon where people just assume that that's possible. And you know, don't be mean or anything. Just point them to this video. It's actually like this is a pretty intense project that you've been working on. And we're doing everything open source. So even even if there's commercial solutions out there that are expensive and you have to get all the special hardware, we're doing this that you could do with low cost electronics. And I'm trying to do it black box because I don't want to, you know, get in the way of, you know, some people's products are like, oh, if you know reverse engineering, they're like really sensitive about that. So I'm just doing it from scratch. So it's pretty slowly. But you know, the next few months, you're going to see, you know, more and more progress. Yeah. We'll have Commodore support. We're going to do everything. Yeah. We'll be there. So in the show until tonight, Kevin stopped by from Digi-Key and they're doing a special project with the Digi-Keyer because it's Digi-Key's 50th anniversary. I said, oh, I actually have a video lined up tonight. It's the 1991 Digi-Key promotional video. If you want to see what was going on in 1991, what state of the art, electronics, computers, and ordering parts via the telephone, watch this video. It's only 48 seconds. It started in 1972. An idea, a new concept in distribution. Today, Digi-Key Corporation represents one of the fastest growing electronic component distributors in the United States. At Digi-Key, service is the key. The success of this effort depends on a team of talents, employees, management, and staff committed to making Digi-Key the best. In its first 10 years, Digi-Key's marketing efforts were focused on the electronic hobbyist. Then in 1982, they began targeting catalog mailings to the commercial market. Okay, let's do some help wanted. We have jobs.adaford.com where you can post up your skills. Or if you're a company looking for people to hire, go to jobs.adaford.com and post up the job. This week, the job is from an electrical embedded engineer for Synchron in Brooklyn, New York. This platform for brain interface technology that transmits data in and out of brain devices implanted inside the cerebral blood vessels using minimally invasive endovascular procedures. Basically, this is one of those things that might help people be able to do things like walk or move or lots of different stuff. Very neat. It's here in New York. It's full time. It's an engineering job. Check it out at jobs.adaford.com. Next up, we have Python on Hardware. A few things and we have so much Python on Hardware stuff we have to pick our favorite. I'm going to skip these couple things right now. I'm going to do this and then we're going to go to the two highlights of the week. Please get what you want in Circuit Python 2022. You can tag it. You can post it. You can look at our videos. You name it. Just hashtag Circuit Python 2020 to the blog. You can also email it to us. Whatever you want to do, get it to us because you help shape Circuit Python. It's not too late. It isn't too late. We go over some of the stuff we've been doing with this floppy work and then a ton of projects. It is never-ending. There is so much going on with Python on Hardware. We're having a hard time keeping up with it. The newsletter is getting bigger and bigger. Subscribe. Go to Aide for Daily. I'll talk about that in a second. But the two things this week that I think is big and interesting news, if you love your brand, if you love your thing, set it free. There is a show called the Circuit Python show podcast, a podcast with people in and around Circuit Python. We have nothing to do with it. Nothing. Yay. The reason I say yay is because Circuit Python has is and will be bigger than an Adafruit project. We fund it. We support it. It's all open source. It's circuitpython.org. You can look at all 250 plus boards that are there. Most boards aren't even from Adafruit. We're really proud of that because people want to use this for business. They want to use it for things. Peditors of ours use it. That's what when we light another candle, it doesn't diminish our flame. We're thankful that we got it started, but we're also extra thankful that people are carrying the torch, so to speak, and doing shows that we just won't have time for. We do this show. We do this show. We do a bunch of shows. Scott has this thing. We have a thing. We do a thing every Tuesday. We have another thing on Mondays. We have our community chat. There's tons of Python books. There's tons of Python podcasts. There's tons of Python videos. I think we're seeing the same thing with Circuit Python now. Speaking of Circuit Python is a friendly fork. We work with MicroPython, that team over there. We like to merge and like to do stuff. We do a couple of different things, but what we do is try to make sure there's parity between the two by working with them. There's a new release, 1.18. What is in the latest MicroPython? Lots of little speed-ups, a lot of bug fixes, improvements to, I think especially IMX Core and SAMD. I think ESP32 got a couple. I think ESP32 S3 got added support. So a lot of little support. Here's the good news. We keep up with releases. Soon after 1.18, we will merge in all of the language library updates into Circuit Python so that we get all those improvements. We also, of course, contribute back to MicroPython as well in many ways. I think this is cool. We're doing a lot of work. They're doing a lot of work. Together, we're bringing more people into doing Python on hardware, which is what it's all about. It's not just the Circuit Python newsletter. It's the Python on hardware newsletter. Yeah, and there's a million different flavors of MicroPython, and there's other ways to do Python on hardware. There's Blinka. There's Stefan Linux. Then there's Circuit Python. It gives you all the hardware support and all the libraries and all the different hardware. So anyway, it's exciting time to be a developer. So if you want, please check out the newsletter. You can get it at Adafruit Daily, delivered to your mailbox every single week. It's separate from the Adafruit.com site because we hate spam even more than you do. Adafruit Daily is where you go. You sign up there. It has nothing to do with your store account. We don't harvest emails. We don't do anything like that. Never will. That's where you get it, and that's this week's Python on hardware news. Thanks, Blinka. All right, open source hardware news. We're an open source hardware company to prove it. Not only do we post up all our files and all of our code under open source licenses, but we have 2,610 guides. Lady, what is on the big board this week? We had a couple of updates. These are guides that got updates. We've been updating templates and improving documentation. We're doing a lot of work with recent boards, but we'll be updating some of the older ones as well, but we're adding nicer diagrams and more getting started tutorials. So these boards are some of those that got updates. Okay, do you want to go to the other side? There's some new guides this week and also more updated. So Adafruit NR52840 Feather, I think it got updated to add code so you could turn it into a sniffer. That got updated, and we've also been adding more to the ESB32S2TFT Feather Guide. For new guides this week, we've got the Neo Trinky Auto Screen Locker by Carter. This is actually a codeless project. It just uses the Trinky as something that when you yank it out of your computer, it'll auto lock the screen. So it's kind of like a little quick security thing. We saw some people making projects like this. The Neo Trinky does a great job, and because it is just a PCB, it doesn't get stuck in the slot. So you can pull it out and you're not going to yank your computer off the table. And then Non Pedro did a 3D printed Tusken Raider staff, and we'll, I think we'll have a video for it shortly. Okay, let's look at some main New York City factory footage. And it wouldn't be factory footage unless you saw our view being blocked by the Disney building being built across the street. I hope the elementals was worth it. Anyways, let's do some 3D printing. You know, just on a side note, if your name's Icarus, you're probably going to fly into the sun. Like, if that's your name, like you're kind of... You only have one job. Kind of like if your name is Stormfield, you're going to be a newscaster and you're going to do the weather. And you're going to do like tornado watch. Probably. All right, so we're going to play the two videos back to back. We've got the Tusken Raider and the Speed Up, which is a fun little Mario thing. Take it away, Non Pedro. Hey, what's up, folks? In this video, we're making a prop from Star Wars, the Book of Boba. We were inspired by episode three of the Book of Boba. The chief of the Tusken Raiders yields a staff that we thought would be really cool to remake. We designed and 3D printed several pieces to make the staff. We printed them in different colors so they're ready to go right off the printer. They can be printed without any supports and they don't need any screws or glue. Each piece features a threaded connector so it's really easy to assemble and take it apart. Start by installing the pipes to the handle by screwing them together. Four of these pieces are then joined with a coupler in between. Together, this makes the length of about 4 feet or 1.2 meters. There's two special pipes with fins that are connected together with this collar. The tip also has fins and just screws on top. Now you can attach the upper pipes to the handle and fasten them together. To finish this off, tighten all the pieces so they're nice and secured. We hope this inspires you to get creative and make your own props from your favorite TV shows or movies. Thanks so much for watching and don't forget to subscribe for more projects from Aida Fruit. And don't forget you can learn how to make all this stuff and more on 3D Hangouts with Noah Pedro every Wednesday. So we interrupt this broadcast to tell you we're going to be posting up IonMPI tomorrow because here's what's happening. You order stuff and IonMPI is the hottest new products from Digi-Key and there's no storms, there's the shipping delays, not Digi-Key's fault. This is just because... It was my fault but the weather didn't help. Usually I can make up for it with what I'm shipping. So our NPI is arriving tomorrow and we're going to post up the video as a standalone video which we do anyways. So stay tuned for that and we'll get the word out. Thank you. Thanks for your patience. Don't forget the code is magnetic. 10% off in the Aida Fruit store and you get just free stuff if you load up your cart and more... Let's do new products. Let's do it. All right so first up. Thank you for singing with me. Yes. Not a good singer, good engineer. Okay first up we've got... This is the most handy thing in the world. In fact last night I was like reworking a couple boards and you know like you sit there and you're reworking and you're holding the hot air gun and you're like this is always going to take like 30 seconds more than you'd like. Like your arm starts to hurt and your shoulder aches a little bit. What if you had a thing that would hold up the hot air wand for you in the exact right location and it was adjustable and then you didn't have to hold it? Well this is what this tool does. As shown here with and you know I have a PCB holder that's these little handy PCB holder magnetic doodads. It's got a base. It's got like this rod. It's got two like rigs with three set screws that you can use to like you know quickly tighten and to attach the hot air wand and that way you don't have to hold it. So I'm taking this one home because I'm so tired of having to hold up this this wand while I'm especially for like four layer boards with a gigantic ground plane and I just want to like reseat one QFN. This is going to really help me out. Let me give everyone a little dash philosophy too. So that arm is a good solution for electronics but fun thing to consider. Get a glass of water hold it out and see how long you can hold your hand out. Eventually your hand gets tired. To me that represents grudges and people shouldn't hold on to them for so long. You can pour the glass of water out you put the glass down but you have to you can't just do that. And so like your arms tired you can get you can you can help it with this thing and you don't have to hold the grudge. You don't have to be in pain. But I like my grudges. They give me life. All right so anyways this is a very nice holder that comes with two sizes. I think all the ones that I used were the small size but you have both and you can choose to just don't attach the one you don't want or attach both whatever go to town. Yeah like this is the most like I kind of wish that this would come with hot air stations but I understand why it's it's something you have to buy separately. But I bought it in a fit of desperation because I don't want my re-workout to become a workout. Yeah all right next up. Next up these cute magnetic connectors which they actually this image is a little unclear but maybe I'll show it on the overhead. So yeah well you know I'm going to show you. There's two pieces yeah and there's there's three sizes there's a three four and five pin connection. Do you want me to show all these and then we'll do the overhead. No let's go to the overhead and then we'll show it. Oh yeah because we've got the different sizes. Yeah but it's it's uh I want to you know you want to do your thing. All right go for it. I know what I'm doing here. DIY little bits or something. So basically um if you have a uh if whoa okay if you've got like a old Mac laptop you might you know be familiar with the the power plug that like um the MagSafe power plug. So this is like that also like sometimes phones or like wearables uh use these connectors because they're very easy to waterproof because there's you know you can you don't have any exposed contacts other than like these pogo pins. So they're much more rugged and durable and also you don't have to worry about things getting yanked out or or getting pulled off and possibly damaging a connector. So each connector has you know three to five uh pogo pins on one side and they're like little squishy pads here. This is the squishy pad part and they have a right angle point one inch header which means that they fit perfectly into a perf board for easy soldering and mounting. So for example like you know it's actually kind of nice you can put it here and then you have another piece um and you can snap it together. This I just we just edge mounted it because this is kind of fun and then this is the matching side which has uh another two magnets on the end and the magnets are like you know north and south are flipped so um it does connect correctly one way but if you flip this around um it will not connect it fights you right because the magnets don't line up. It'll naturally want to uh connect if I like even if I hold it backwards it'll go well if it's connected something won't do that but it'll magically snap and align that's cool so the five pins are connect correct. So you get there's a three pin a five pin and a four pin version like docking things like yeah it's like I think it can be cool like we can have circuitry and this can carry power and data so you can have multiple boards and you know three five and four pin means it's like you can do you know you are I squared C power this is cool you know one wire and uh I like particularly the ones you know you can always bend these pads but I like these right angle ones because you get nice long uh contacts and uh they're very easy to solder and it works with like any existing design that has a uh header contact it just plugs in or solders in that's cool this is neat this is a very like these are very fun and they're finally they're not cheap I'll say but they're magnetic and you know magnets are expensive and and they're precision and you know getting one off is is not so cheap but believe me you couldn't get these a couple years ago and I was looking and I was looking and I was looking trying to get them but now that they're they're more generic and you can actually pick them up in multiple sizes so cool okay next up next up and this is actually also you know the star of the show we've revised um our seven segment backpacks they're the same size the same pinouts the same everything except I kind of redid the back I improved the design a little bit and I made them a stomach UT compatible so um if you want you can use the old ones that's fine and you want to use the new one um the back has yeah so yeah star of the show night beside delay date and one of our customers our team in the community it's this yeah I just show the other things for that's fine they're they're beautiful and animated uh on the back are two stomach QT connectors and you can change do we show the product yeah yeah and I mean like let's go to the overhead and I'll show it because it's it's a little more clear that way yeah I want to show these photos okay that's fine well this is the the board and then it's like it's stacking on with the red yellow green blue um so this is it with the matrix solder on usually comes bare and you solder on whatever color you like there you go uh and you get the clock display with decimals and uh colon it's still got the HT 16 K 33 which uh is a really great low cost chip um I actually brought in the pads a little bit to make it easier to solder there's a power led which you can um cut the trace if you don't want it and then there's two vertical stomach UT connectors and so um here we've got a demo of a cutie pie board with the stomach UT cable plugged into the back and it's just like writing the demo and there's like you know we just plug and play it so um I do eventually want to get these pre-soldered like with the um light box in them for now they're still a kit but I'm getting closer now that at least um this says a little bit more space it's easier to solder and uh you can plug and play up to eight of them on one I squared C bus because the address can be selected on the back there's uh three jumpers to select up to eight different addresses so the backpack you know and loves one of our early products um people really like this and it's makes it really easy to add seven segment displays and now you can plug and play them with stomach UT and that's new products all right y'all don't forget the codes magnetic 10% off the native restore up till 1159 p.m probably even a little bit later because what's happening is I've been getting up so early that it's hard for me to stay up past 11 I kind of just like crash out so you might have a chance but you should still try to do it by midnight um let's uh go to top secret and then we'll answer your questions post them up in discord adafruit.it slash discord if we're not around don't worry there's 32 000 of us around all the time at some point but uh we're gonna get to your questions right away let's do some top secret first though oh let's look in the vault from the vault um so I'm going to play two fast videos it's esp 32 pico and the cutie pie esp 32 s2 and then we're going to talk about some of the new stuff we got hey lady what is this hey I just got some samples of these new esp 32 pico modules I got a cut tape of 10 pieces and what's interesting is um I actually couldn't even realize that these are not the same size as the esp 32 s2 modules they're like kind of like significantly smaller which is actually good news because I like you know I was talking earlier a few weeks ago I wanted to make an itsy bitsy esp 32 and this like will just fit right in between perfectly and not getting the way of the pads it'll just have to put the silk screen on the bottom um and then I just need a cp2102 and um the power supply but you know if I can't quite fit it here I can put some parts on the bottom maybe so I think an itsy bitsy esp 32 is in the cards it'll have ps ram because the pico comes with two megabytes of ps ram so it's kind of cool so cute hi lady what is this this is me testing out prototypes for a new cutie pie board it looks a lot like the esp 32 s2 cutie pie that we recently released but this is the s3 it's a dual coat dual core tensilica 240 megahertz processor with wi-fi and ble so it has a second core and ble compared to the s2 this is a really new chip so support is still like very much in progress um but we do have the beginnings of circuit python with wi-fi working on it including some peripherals so this is um me running the wi-fi demo and thanks to scott who fixed a couple of hard faults I can connect to wi-fi I can connect to you know github and get the number of github stars so it's slowly coming up um still a couple of things to work out but um this new very powerful cutie pie is going to be in the store soon all right and then you get a new feather yes this is the new esp 32 feather so it got like a huge redesign um with that pico board and now has two megabytes of ps ram and um I think eight megabytes of flash I think that the pico has like double double and um also the usb serial converter can be a cp 2102 n or cp 2104 at a stomach ct connector usb c it's just like a big reese rerun you know okay I kind of cleaned up everything and read it a bunch um added an extra user button because there was an extra like single pin a few a few gpio had to get shuffled because the pico doesn't expose every pad but I think it's worth it so I'm going to call this as a v2 it's a new product but I think you know people should upgrade it'll probably have a lot more functionality um and uh more power supply options and more memory of course I think it's a worthwhile upgrade and next up this is a preview we have pink gst connectors yes I have to actually try them out but next time I build a board with jst connectors I haven't had pink boards with pink gst connectors we're gonna uh blackboards with pink gst connectors we're gonna see which looks best we're gonna try them out and then we're just gonna start doing it yeah and that's top secret okay we're gonna roll right into questions and we're gonna get out of here so I have a few lined up from the chats yes and I'm gonna start getting to those now okay first question question for the chat the esp 32 s2 feathers can I plug in any solar panel into usb for charging and attach life of battery is it smart enough to handle the over under voltage absolutely not you can't do that you need a specialty solar charger um which is we we stock separately it uses a different chip it's much more expensive it's much bigger um and then you can use that to generate um you know the the to manage the battery and then you take the load out from that and you can use that to power your circuit okay next up 24 24 volt power supply to five volt for esp 32 buck converter or voltage regulator I think you probably want a buck converter otherwise you're going to dissipate a lot of power as heat okay question my work we spun a board to accommodate a bga chip versus qfp chip due to the chip shortage can you oh sorry but our normal board supplier cannot make the board anymore because of the bga is this common can you briefly explain why and perhaps touch on the different levels of sophistication quality of board houses um that's unusual that a board house won't do a bga unless there's something you're doing like um via in pad and you need plug vias like there's there the pga is probably not the issue it's probably something else that got added to your board design because the bga because bgs aren't that fine pitch um they're annoying they're complicated and they're hard to rework but they're not fine pitch they're usually you know 0.5 mil pitch or higher um but it's probably some technologies that you added um to your stack up that has made it so your board house doesn't like it anymore and that's up to you gotta talk to your board house what is it that they can't actually do okay uh next up when will there be a neokey five by six ortho snap apart for chalk no idea okay they're not that popular to be honest next up uh the feather nrf 52 840 since doesn't seem to have an on-board pcb crystal oscillator like many other feathers what drove the design decisions is there a big difference between the clock act receivers other feathers there is a crystal you just can't see it it's in the module whoa um next up uh do we ever work with cnc machinists for any parts um not often usually we know we laser cut stuff but we don't usually uh you see and see in our processes next uh part shortage is it getting any easier for you to get the parts in you no it's in fact getting a little bit harder um because some parts are they start to just get discontinued like we have them on order um and you know for a few months we could we held over with what our stock had but it's actually getting the it's getting tougher to get some parts and even though we've booked them um they just get pushed out like we have orders that we booked a year ago that were promised for months you know and then it's now a year and it's like we still don't have the parts so um it it's you think you would get more used to it but it actually doesn't actually gets a little tougher um because it's hard to trust anything so everything is just you know I mean if you're like it's it's not the parts shortage just the problem it's not knowing when the parts shortage is going to end that's the problem I think this is like the frog boil thing where it's like it's been one degree hotter one degree hotter one degree hotter and eventually like right now it's like ow we're boiling yeah the tft prices have come back down so that at least yeah some result would the feather wing for floppy drives worked with an internal floppies uh for example a internal floppy on a powerbook 145 not sure the level of work if we use a breakup board probably not a powerbook because mac floppies were different and they they may not have used the same sugar interface um so they are they are different um mac floppies in in a certain era which you know had variable speed drives like the superdrive were we're kind of a nightmare eventually um there was a period I think where they stopped supporting old floppy disks but basically now it's it's really going to work best with pc floppies all right scroll oak we got to the esp 32 s2 feather question about the solar panel just hit rewind on the video you can also wait till the video is done uh just a few minutes back um the answer is you're going to need another device um and lady it goes over that question I asked this on the site but one to add a thought you are revising esp 32 boards any plans to add a stem of port on any of them uh it can make whipper snapper easy to connect a pr sensor ideally sorry preferably like the pin to be uh interrupt capable for deep sleep wakeup projects I know it's easy to solder but you know like easy quick that's like the fun house there's really no space I mean you could plug this into like a grove wing or something but if you if you're looking for something that's whipper snapper you can plug in stuff without any soldering that's the fun house board okay uh after an awesome great search about pcb wire terminals I fell in love with some corded wire terminals on digikey do you think I can use those in design or will it make the antsy iso people mad could do whatever you want I don't care I don't care they're meant to be used uh I think uh if the software's in place would an IBM compatible 5.25 inch floppy drive be able to read write common or floppies I think so I think common or 64 floppies are read read writeable from a standard five and a quarter inch disk drive I mean like I was able to read some common or 64 diskettes um not the copy not the copy protection stuff I'm still trying to figure out whether it can it can do that it can't easily do the flippy disk part like flipping over the disks a double sided where you actually like take it out and rotate it because some common or 64s you literally had to remove the diskette and flip it upside down whereas modern five and a quarter drives have two heads um so this is what I call the flippy disk um there's a lot of things where it's like floppy disks are fascinating they're they're a lot more incompatible than I thought even even some things as simple as like well you're just reading flux you know everybody wanted a kingdom and they made it all difference and nothing worked with you it's it's actually a little surprising it's like there's there are some real weirdnesses but I believe the 1541 diskettes single the single side you can just read and write um with something like eight of fruit floppy on on a standard five and a quarter inch pc disk drive because inside the 1541 I have one that we picked up for like 20 bucks and I believe they actually just used a standard off the shelf five and a quarter inch drive and then just added their you know their controller their 8051 controller on top but it's it's very hard to get consistent information about this um it's out there but it's a little I don't want to say gate capped but it's a little bit gate capped it's not oh I'll say it um so there's a couple things going on a lot of the websites are older and they're not being maintained and the domain names are gone away and it's in forums that don't work anymore and then some of the people um are super gate keeping and they don't want uh beginners in they don't want uh people like Lamoran and so we're doing everything in the open and we're doing open source but that's one of the things that happened with electronics speaking of 15 16 years ago yeah there was a bunch of gate keeping folks that didn't want people like you and people that are beginners into the electronic community and they purposely kept everyone out and that tension still exists now especially with retro stuff but it's changing because the eight of fruit community is really interested in this and everyone's sharing and folks are helping each other out and the eight of fruit floppy stuff is open source and I think folks are going to help make it better yeah okay next up um do the mag connectors come with pogo pads on both sides no there's pogo pins on one side if there was pogo pads on both sides they would it would not fit very well like you want one side flat and one side springy all right uh do you have any suggestions for dealing with noise on iceward sea I have a strong 1k pull-ups but still having communication errors eventually after minutes of connection you can slow down your speed you can use an active terminator um you can make sure that your your ice-squirt sea and data lines are not next to each other make sure your power supply is good like your ground isn't floating around those are some of the things that by the way ice-squirt sea I will say it was not designed for more than four or five inches really that's max max but we are abusing this interface with wires so you'll you may need an active terminator it does help quite a bit okay um so folks have some suggestions the guy who does the adrian basement channel he does the common or stuff by heart we'll check that out and yeah there's there's there's you know the common or stuff and there's the you know how what you have to do with the disk at it's a lot of common people like to use the 1541 disk drive and then and then as far as I can tell they solder wires onto the data output port and then connect it to a parallel port like it used to be a parallel converter and read the data that way and then I don't quite get why I haven't quite figured out why is that the way you have to do it why not just read fluxes off of and you know a standard pc disk drive you don't have to mfm decode them um this should be possible right I I know that there's there's a reason why some mac floppies you can't do that but for um gcr there's I don't believe there's any reason you can't but again this is a lot of the data is a lot of the stuff that people are talking about it was a lot of people doing this hacking in the 90s when there was there was restrictions on what you could do like it was actually easier to get a parallel port than it was to get a mic control with 128 k of ram if you have a mic control with 120 k of ram like there might be ways around some of these restrictions to like buffer an entire track and then do the gcr decoding and do the analysis um yeah we have boards with like four megabytes of storage I mean like yeah it's basically it's it's unclear to me at this time okay um folks that request for scuzzy and tape backup drives yeah we'll see I mean it's gonna be an open source project we'll see what happens uh I think that is it okay we got to everything got to everything okay so that is our show tonight everybody don't forget the code is magnetic that'll be gone until uh either I fall asleep or I wake up one of those two things trodding there's fill blocks um is it a sleep fill or is it a wake fill um either way the code's gonna go okay until uh I remember turned off so fill up your cart and more 10% off all the stuff that's in stock thank you for your support everybody thank you to our community our customers our folks behind the scenes jesse may is in the slack chat tonight hello jesse may um all of the eight of fruit team members all the folks in the chat um special thanks to new york keeping it together it's been a grind but we're getting through and uh we'll see everybody next week same time same place asking engineer this is an eight fruit production and uh here's a moment of zener bye everybody
