 Well from New York it's Ask an Engineer. Hey everybody happy New Year. It's me Lady Aida the engineer with me Mr. Lady Aida on camera control. We're here at the Aida Food Factory behind us all the machines that make your dreams come true And make some hardware. Yeah, we do all of our design and coding and testing and shipping and all that good stuff yeah a jam-packed show for you about one hour of maker goodness news from around the world and more Mr. Lady Aida Why don't you kick it off and tell us what's on tonight's show? I'll tell you what's on tonight's show just first up We're wearing masks right now because we have one more person who's here and as soon as they're gone We'll take off our masks, but this is how we run Aida Fruit Lady Aida and I live together. So once the last person is out for the day We'll be able to take off our masks. I'm not concerned about us. I'm more concerned for Jaime The person who's still here Because I wouldn't want to get him sick. Okay, so let's kick it off on tonight's show. The code is New year is here. 10% off in the Aida Fruit Store all the way up to 11.59 p.m. Or if I don't remember it'll be up in the morning New year's here use it save 10% off get free stuff and more an Aida Fruit store on the way out Get Aida Fruit live series of shows. We'll talk about those including show and tell We got some time travel look around in the world of makers heckers artists and engineers Main New York City factory footage. We got a bunch of 3d print in we got everyone's favorite segment I an MPI brought to you by Aida Fruit and did you keep we've got some new products We got a bunch of top secret. We're gonna answer your questions. We do that over on discord Aida Fruit that IT Slash discord join us there all 32,000 of us Tonight's gonna be a big show all that and more on you guessed it Ask me that's right Okay, so let's first do some COVID news so Y'all seen the news everyone's starting to get back from holiday. It is vertical. So everyone Pretty much at Aida Fruit is in some stage of getting tested at some point So Aida Fruit seems to be beating the odds once again our teams vaccinated boosted They're getting tests rapid tests PCR tests We wear high-quality masks. We have staggered shifts. We have lots of room. We have lots of airflow We have filtering. We've been doing all the things. So this wave is hitting everybody really hard and there's a lot of scary moments because People in their families are testing positive and they have very mild symptoms because they're boosted in Vax but it's still scary to get that news and The way Aida Fruit does pay time off and all the things is others focus and takes care of our team However, I know that's not what's going on in the rest of the world And I know that's probably not going on maybe where you work and I know that's not going on in probably your life and I know we're about to get through this because I could feel it thrashing It's Lassa gasp, which is the good news. The bad news is Everyone lost empathy for each other People are getting meaner and worse to one another People that are normally pretty decent This is it's It's frayed them to a point where they might not have any other way to react or interact online Other than anger and pain and depression And we're all going to be stuck with each other on the other side And I'm really worried about the damage that's being done With that right now You know, I could just say Just from a company point of view with Lady Aida and I She's had stalkers harassers people threatening her you think that was Something that would get lower over time it just goes up and one of the reasons is everyone's just been out of their minds for the last two years So it's unfortunate that everyone is is doing this and we are going to be stuck with each other So I'll just say please be good to one another because Bye bye. Hey take care um Because uh, this is Until further notice there ain't another planet to move to We're stuck with one another So anyways, um, that's that's the biggest that's the biggest concern I have right now is um, we're about to get through it But What's coming out on the other side is is is uh, probably a big national camp conversation that we need to have with each other Anyways, so uh, that's what's happening there and I'll be gone in a minute. Um, so let's start doing the show Lady Aida We give away free stuff That's right We're doing freebies. Um, we ran out of pink feathers, but we have black feather RP 2040 is available. We still have a couple left. So we're going to do Um that freebie. However, it's going to go away soon So, um, if you want a free feather RP 2040 for $9 or more a place for order now Um 149 or more you get a free um stomach qt board We have a bunch of different sensors and breakouts available $199 or more free ups ground shipping in the constants united states and $299 or more a free circuit playground blue fruit We'll also be going back to the circuit playground express due to the shortage It was a little hard to get samd 21 chips, but we got some more. We're gonna be making more of these And uh, we'll be back on track soon Okay, we do a live series of shows sunday. We did desk of lady aida today We did show and tell jp. Thank you so much We were running out of time today and I emailed jp and I said And no pager. I'm just like, hey, I think I might have to cancel the show and tell and I really don't want to do that and Ask an engineer just because everything that's going on. I was going to bump it or Not do it. Um, because it just takes a while to put these shows together And we were really focused on taking care of our team and just everything Um happened all at once. Um But thank you jp for doing this watch the show until everyone go to our page a to fruit dot com slash blog where you can watch it on youtube at any time Relive the magic on sunday. We do desk of lady aida and over the holiday break We've been doing retro stuff. So what was part one of desk of lady aida on sunday? Um part one That was even new years. It was new years. It was new years eve And it was going all the way up to we did a project right as it hit midnight Yeah, so I've been working on um floppy disk Interaction and um, I think on new years eve. I actually got floppy disk reading going so There's a bunch of one-minute videos as you see me learning how to interface with floppy disk drives Um using hardware. We're going to add circuit python support for floppy disks Um, but also it's really good for archival purposes. Um, you know, I even like as of like two weeks ago I thought a floppy disk and a floppy disk turns out there's like different formats and sectors and encodings And spindle speeds like this technology was you know used for Um, 20 25 years and a lot changed So, uh, I learned a lot and we were writing up some of that and documenting it But also you can watch the videos Okay, and then we did from the desk of lady aida the great search related user powers of engineering To go digikey.com and you were finding cool parts and things you needed and more and what did you what did you look for this week? Um, so this is for a floppy disk. I wanted to find the matching power connector, which is called a burg connector Um, you know, which is ironic I you know a lot of connectors are called by the name of the company even the company makes like hundreds or thousands of different connectors Um, but I found the connector showed where to get it on digikey And also even though floppy disk cables aren't made anymore I just found some suggestions for like here cables It'll probably work if you want to connect From this chosen connector to a floppy disk drive to power it. Yeah Okay, jp's part of pick of the week is back. We'll come back jp. Here's a highlight from this week's show It is the at tiny eight one seven seesaw breakout board what we've developed and we use on here a lot is the seesaw framework that is a I squared c to anything protocol. This is the rp 2040 qt pi I'm just speaking i squared c between these two things a lot of the heavy lifting is right here on the seesaw board So I'm reading a potentiometer And I'm taking those analog values and I'm actually converting them into pwm values to change This brightness on my yellow led here. I'm reading this little switch here This is actually a neopixel right over here And my potentiometer is serving double duty when I'm in this mode. I can Change the speed of a fade between a couple of colors or three colors to be precise It's the at tiny eight one seven seesaw breakout board Okay, and john's part workshop will be this thursday tomorrow Stop by and you will also be able to Check out the circuit by thumb parsic that resumes too after the winter break scott will be back this week Thank you tim from a guy for filling in for scott on deep dive, and I think scott is doing Some wrap up on some raspberry pi stuff raspberry pi zero. I think um sd card and uh usb wrap up getting some of that Stabilized learned a lot and he seems like he's like he said he's got fresh eyes and he's excited to go in and Knock out those lost few bugs. All right time travel Let's look around the world makers hackers arts engineer. We have a sort of new segment ish that I wanted to talk about um, but first uh a little bit of reminder because of supply Shortages because of all the things that are going on on planet earth. We've moved aida box to additions So before we tried to get uh some of them around some specific holidays Absolutely not possible in uh this current timeline universe So what we decided to do is say no problem. Let's just make it additions And then we're going to not have to hit a specific date We'll just have a range of times because there are four seasons. Um, so next year we'll be shipping the winter edition um, assuming something else doesn't come up, um in uh late january, uh, well, sorry this year, uh February so probably be february just the way things are going right now So, uh, there's only like a couple of slots left So if you haven't got an aida box and haven't got a subscription, we'll be full soon. So go to aida box.com Um, we started a little series. I hope to do more of this here's lady aida from high school A little bit after high school a little bit after high school, uh, but really close. I do have a lip ring I want to say I didn't get that till I was 18 But I've seen the picture of you in high school. You look identical. I look the same So, um, we did this little series called tails from the hack Where we and I put this up on our blog and it was because we were walking around after we've been doing this floppy project And uh, it kind of just hit you and you told me the story and I'm like, oh my god, the story is so good I must I must I must email Mudge who's now the cto of twitter and joe gran kingpan and see if it's okay to post this story So lady aida take it away. What is this? Uh, thing that happened when you were in high school um with Joe gran and mudge kind of people well-known people in the hacker scene at the yeah at the time they were um local boss and buddies in the six one seven crew, but um When I was in high school, um, I was uh, I was helping out in the it department and Um, they were talking about a bunch of old like apple and and coco and Here I say like really old computer stuff that have been in the cage Are you saying in the high school? You did computer stuff and you were uh doing stuff at the it department. It's true. I'm shocked I know at the time it wasn't so cool But I was I was just you know the it director. She was really awesome And I think I was just helping organizing cleanup and she was going to dumpster all this stuff And I was hanging out with a lot of hacker crews and and hacker houses And um, you know one thing that I knew about hackers is like they love old hardware, especially free hardware And so it's better if it's free it does taste better So I you know, I called up or I emailed or I messaged kingpan Maybe I paged him losing page yourself and I said hey, um come by the high school And uh, help me dig through this this trash and maybe we can find something cool We could either sell it at swat me and we could recycle it into some projects Um, so Joe, Joe Graham came by. Um, he does a lot of hardware hacking stuff now And does does product design for power lacks among others Um, we dug through some hardware. We I think we got a pile of apple 2c's And then we had to get it. Um, I think to the loft and you know me and Joe grand were like We weren't dry. We didn't drive. I think he was like 18 or 19 And maybe didn't know a car and I was I don't think I was 16 I didn't have a driver's license yet or at all and um, so he's like, okay, let me call um much so much came by and he he drove in In this like incredible car like the coolest fucking car. This is not the actual car, but I asked much This is pretty close though. This is it's the same car, but you know, I don't know if it's a King must 90s. It's a cobra. Yeah, it's a cobra Mustang. This was the coolest car ever What's funny is you asked much like, oh, what was that car? He instantly like knew all the specs and mod I mean, he loved that car Um, he drove up in this like sweet ass car in front of the quad world, you know after school Where all the kids were like smoking and um, skateboarding and and whatever hanging out because it's kind of the outside quad area of the high school And it's like car drives up and it's just like this totally bitching car and I get in with these apple two C's And like everybody in the high school was like what? What the hell why why do you have a friend with such a cool car? Why were you carrying some apple two C's? And we thought you were a loser, but it turns out that you your friends are cooler than ours So I was like I was kind of cool for like two days So let me tell you some parts that lady does not gonna say. Sorry. Um, so, uh Well, first up, let me just do the big thank you So thank you mud and joe grand for being you because they saw something in this young woman who was interested in technology Who is getting um made fun of a lot who is getting tormented a lot who is told don't do this This isn't for you girls don't do this all the things that happened Still to this fucking day and I'm kind of tired of it Like like today we got an email. How dare you do retro stuff? How dare you do this? This is mine It's so terrible what people do to each other. I actually love the people think I'm like 25 Like I'm much older than that and I'm sorry to curse, but it bothers me that when you told me this story I was looking at a tweet that we had to block some guy because he was being so shitty online about You liking technology. This is a waste of time. Why is this? Why is this? Uh Want to be got I'm not gonna even say the curse words. Yeah, but like why why is your experience have to be so much different? Like if you were if you were a young boy, it would be like, oh, look how he liked computers It's so good, but because you were a woman I don't know. I think we we live in a society that I don't like it I don't like it and I'll say this for 2022. I'm sorry everybody like we have to call it out We have to say stop I mean we're going to be positive and we're going to show good things But it's a little ridiculous that the day that we're getting this story and you're like, yeah The people made fun of me and I was cool in high school just for like a day because of this And we're like dealing with people being shitty to you. I don't like it I don't like it and here's the other part and I shrugged up because I think it's not a big deal I I shrugged because it's it is, you know, I agree So I have a let me put it on time travel because I don't want I don't want I don't want to Even have the apple logo. Look at this So Sorry apple logo. Look away cover your little rainbow eyes. You're too beautiful. Yeah So I remember I was talking to a CEO like person of a company that's very similar to Adafruit And I was telling them about something that we had to deal with we had to Basically get a restraining order against someone because of something that they said did sent mail just Physically anyways, it was a messed up. It got granted. Yeah, and it was a messed up story And they said, oh, you know things can't be that bad And I said, have you ever gotten flowers delivered to you with a death thread and saying I'm going to cut your head off because you're Trinity from the matrix Have you ever had to deal with having Making sure there was enough people around going to an event so they didn't bother you like all these things He's like, no, and I'm like, yeah So like please don't say like it can't be that bad like your experience You're like, oh, I have to like run a business and it's really tough Well, not only does la more have to run a business, but she has to deal with all these Things constantly like today. It doesn't make the debugger run any faster either Like I still have all the technical problems too. Yeah, and like eight of your worked out. Okay I would say we're a successful company. Can you imagine if you didn't have to deal with all that stuff? How much more hardware you can get out? Yeah, so anyways, I'm a little upset because I thought this was a beautiful story, but I also know the other side of the coin So maybe I'll edit this out later. Oh, we're live. I can't okay. So that's our tails from the hack Let's use the python news. It was a good story I still have the tier s80. I think back in my parents place. Go see if I can dig that out Okay, it's python on hardware time So this week in the newsletter, we've got a bunch of stuff going on circuit python 71. Oh final is out. I'm going to skip This part which is I'm going to play a video the nine part video of us getting ready to get floppy support Being able to control all this cool retro hardware with circuit python But the most important thing this week, please everyone everyone everyone everyone as 2022 starts For the last three years. We've put together a post 2019 2020 2021 even though some of those years probably should be removed from the calendar Um, what we want is you to tell us what you want in circuit python Um, just put your thoughts in one place. Tell you tell us what you like about it Tell us the things that you want to add to it. You can do a video on youtube a post in the circuit python Stuff you want to do a blog post A series of tweets a guest on github Or you can just email to circuit python 2020 at aterfruit.com and just let us know if it's okay For us to post your thing that you send us on our blog and more You can also use the short url. Well, it's short ish aterfruit.com forward slash circuit python 2020 and that'll take you to the blog post and more what's cool is you can see Circuit python evolve All this time because we built so cool a good community together a good community of people That is very inclusive that would always give you a ride in their cool car So and give each other right and what I like is um every year you see stuff that we say we're going to do You know and most of that list actually gets done like we are Making constant consistent progress both on the community side documentation side the hardware side So many little things that you know when we we work fast and work hard. There's a lot That we've added We have like over 250 board supported. We have hundreds and hundreds of libraries supported With blinker we support another like 50 linux boards and like believe me if it didn't work We would get a lot more emails. So it's it's really working out Our hardware other people's hardware people are are depending and using on Adafruit libraries, Adafruit software, Adafruit firmware, Adafruit hardware The whole shebang and the cold thing is everything is totally open source. So people Are mixing and max mixing and matching it with other hardware Getting stuff working and uh having a really good time. So Join in circuit python and python for hardware is is something that I think is Um Has really uh been an important change and update to the way people code in the maker community and engineering community I still like code in Arduino cc plus plus assembler and and other people do too and that's fine, but I think this is a really welcome New family member. Yeah, I like the um post holiday tweets and uh Emails that we get because folks say oh I was able to get a project up and running in less than an hour Because that's all I wanted to spend on in anyways Yeah, and they didn't have to do a toolchain. They didn't have to do anything. They just plugged in a board They modified a little bit of code and now they had this like beautiful blinky thing for their, you know, granddaughter or something like that So I thought that was um, that was really nice here And by the way, that's the other side of the coin sometimes, um, you know One out of a thousand things ain't great, but you have to focus on the 999 Um, I gotta tell myself that a bunch too. Um, so check out this week's newsletter. There is a bunch going on Professor John Gallagher has a bunch of stuff going on. There's a video on programming The Fibonacci micro 64 led board using circuit python codes on github and more You can make a riz five chip runs circuit python. This store was really cool, by the way Um, there's a circuit python online id update And then um, don't forget scott's deep dive this week And then we have some other news that you know, usually folks who are tuned into this stuff Or even if you're not maybe you want to know about it. Uh kai kai six Sorry key cat key cat six is up. You see key cat. I'll say kai kai and together we've covered it No, we should uh hate each other forever and kill the key catters And uh, you know, just dunk on each other forever and uh completely be jerks about it. Um And so anyhow, what I wanted to do is make sure we built in enough time this week Um, I didn't really expect to do a ramp, but I didn't sorry and uh play the video So we have rand of 2022. So proud of you. I was not at the first rand at the time This is the first one that's been broadcast So, uh, this video that we're going to show now is beginning to Almost present so it's nine videos in one nine one minute videos all together about eight minutes and it has zero to getting uh a raspberry pi pico rp 2040 to completely control read write archive A floppy drive with a floppy disk in it. So it's super cool All right, here we go. Lady. What's this? Okay, those are index pulses coming from this floppy drive that I am interfacing with I just got you know, the first kind of parts going where I enable the motor And I'm setting the direction. I'm going to you know, get the index pulses and then I'm going to find out when it's track zero Um, so basically kind of trying to read data off of this floppy drive so I could add native floppy disk support to circuit python Soon, I'll update this to maybe use the rp 2040 as well Um, right now. I'm just writing the code in our duino because what I'm familiar with so I finally get all the idc pins set up the way I needed to what was really helpful was this Really really nice modern datasheet from samsung for the sfd 3 2 1 b So it actually goes through everything you need Um, and so far so good. So I've just started basically getting the motor running The floppy disk is responding so far so good You know, uh, I want to copy that floppy. That's right Here I've got some more stuff going on with my floppy disk controller that we're going to add to circuit python So yellow traces you can see is the index pulse that goes low and then you see this like Moving blue line that's actually data coming out of the floppy drive If I click the single button you can see the data comes out and it comes out as these pulses that are like You know, they're they're supposed to kind of be like a pwm But they're actually just very low low pulses and then there's a pull up to pull it up high And you can see that the data comes in You know in in various widths and um, so that's actually the tough part of reading a floppy is this is about 500 kilohertz And the pulse width varies including the data. So over here I'm actually doing something a little naughty. I'm not using a pll I'm actually just very very quickly in a no interrupt loop Reading those pulses and printing out the pulse widths and I'm going to see if that's good enough to read data from a floppy drive Nice Nordic shirt. Lady at all again. Okay, so Part three of my floppy project is I've got the data coming out of the read pen And this is a gpo pen. I'm toggling up and down to show that I'm properly reading the pulse widths For the data that's coming out mfm format and then what I've done over here is You can see I'm capturing flux transition And I've got a cortex m4 here with like 256 k of ram And it's actually totally fine for me to just buffer the entire track of flux transitions because there's only a hundred thousand Transitions maximum per track Um, and you can see that there's a little bit of bending here So there's a couple pulses, you know a lot of pulses around 40 And then down here we've got pulses around 60 And then finally we've got pulses around 80 You've got a couple extra long ones, which is a little bit weird. Like why is it 228? So a little bit more to analyze here, but I'm starting to get data coming in and data looks right Lady, what is this? Okay, so we're doing some floppy drive hacking and I've got this like original three and a half inch floppy drive But these actually hard to get because they're not made anymore So I was wondering, you know, there's these off the shelf usb floppy disks And you know, can I somehow use those so I opened one up I cracked it open And actually has a sfd 321s sim some Three and a half inch floppy drive with a little adapter here and the adapter's got a little cheap chip on the back And there's all these points here And I'm hoping can I get flux transitions out of here because I don't want it to do the translation for me I want to get that raw data. Well, good news. Um, I found a really nice person Well, I actually did the pinouts and then when I access the disk you can see on the scope I get my index and flux transitions. So, you know, normally if you use these usb floppy drive converters, you don't You know, they give you like a usb mass storage, but this way can get that archival quality flux transition data Lily, what is this? Okay, I still got my Panasonic floppy disk drive and my feather that I'm interfacing with And I've gotten flux data out and now I want to get that flux data from the disk drive and the feather into the computer So I'm using this open source tool called grease weasel and I'm updating it to support um This setup that I've got here. So basically I'm reporting the grease weasel firmware into arduino So far so good. There's some like flux opcode thing that I got to figure out. Like I've got the flux data leaving here You can see it's got the flux data sent and then over here it says, okay, I got the flux data But then they're after like somehow encode the index. So I'm getting there. I'm close to getting raw data dumps Onto my computer using totally open source hardware and software. Okay, happy new year. Happy new year What is this? This is the first floppy disk. I'm going to try reading with my grease weasel compatible firmware on this feather m4 hooked up to this floppy disk um, so I've got flux data and track seeking working and I'm able to get some Tracks working like some tracks are reading just fine I'm also getting some tracks where it's like it doesn't see any sector data And I think that's probably because like the flux data format. I'm sending or the index Whatever I'm sending isn't quite right But for those first few sectors that I do get working The data is good. So I'm just going to have to figure out what it is that I'm doing that slightly wrong But I feel like I'm getting closer. At least I'm seeking and I'm getting some data Working from the beginning of the disk track What is this? Okay, I think I figured out all my power supply issues and my flux timing issues And I'm really ready to read the secret disk that I got that they hidden that place that one time Right. Thank you, Esenburn. So I'll put this in my floppy drive and then over here on grease weasel I'm going to start capturing Track data So I'm going to capture all the mfm ibm pc sector tracks all 80 times two heads So 160 total tracks Hey, so we have read all of the sectors a hundred percent. So it's ready to uh, open up Win image. We're going to open up that secret Image. Oh my god. So it's gonna open but I'm gonna open it anyways. Yeah, let's just open it Oh, no And I've got rick old my my own floppy disk Okay, so we still got our floppy setup going on here where we're capturing flux traces from a three and a half inch floppy drive But I've replaced The feather m4 samd 51 with this pink feather not just because pink is a cool color But because this feather has an rp 2040 on it Just a low cost chip from the raspberry pi foundation and this chip can run really fast also has a cool pio Uh peripheral so we're overclocking it to 200 mega. It's good. Why not? We're getting good, uh, flux captures over here And when we recompiled it and we're running a grease weasel. It's just working So this is cool because now I've got two different platforms that work with this arduino library Which is the goal to make it hardware agnostic some more people can Wire up hardware and build hardware to work with floppy disk drives and then next up Maybe we'll try this little fellow the raspberry pi pico four dollar microcontroller board What is this? Okay, I'm wrapping up for the night. It's gonna lay time to maybe do some yoga and chill out. Um, so I've got Um, the final board i'm going to interface with this is the raspberry pi pico. So this is a four dollar microcontroller um And the reason i'm targeting this is it's available like digi has 17 000 of in stock and Some of the hardware that people are using for open source floppy interfacing isn't available because we're in a silicon shortage But this chip is available. So it's nice is that the pinouts like kind of line up very nicely. You can um connect them straight through to your floppy disk drive um, and then load the arduino code onto it and I set up the pinouts all nicely and um Test of it. Uh, I read a whole floppy just fine and then I've submitted this to the um arduino library registry So you'll be able to get releases and maybe I'll even have it auto generate uf2 files So I think i'm done for tonight. Maybe time to celebrate good work glass of water. Yeah Okay, and let's strike a python news for this week. So this is beginning middle and Present to get to get us where we wanted to be so we would be able to start to add support for all sorts of removable drives and more Um, you know, we got some dunks and snarks about why would you do this? Well, there's a lot of media that is about to Just go away forever unless we preserve it Put online and more and also you can't get hardware. So you may as well Can get new chips get old chips revitalize this hardware that a lot of people have instead of throwing it in the landfill Yeah, you like the planet, don't you? Yeah, this is a good way to reuse it And um, so we're adding circuit python support the jeppler's working on that And um, I'm going to get back to adding more arduino support, uh shortly took a little bit of break Um, just to get back to business stuff to get all the new products in the store We're gonna talk about shortly But more to come cool, um never ending. Let's uh jump to may new york city factory footage We're gonna do 3d printing then we're gonna go right into ion mpi and then new products in some top secret And we should just be able to get it all in tonight. So take it away I can get us out of here That's time for may new york city factory footage And y'all are gonna like this this is the entire year of the um, disney Wow building Being built across the street So, you know a little bit of a slow start because you know, you got to dig a big hole You have to put down the foundation and then like it just goes And so this was built on um, we need the poo no, um, this was well Yeah, I kind of now that's part of its public domain You just have to make sure you don't put the rich shirt on um, and that is uh, this week's main new york city factory footage Okay, let's do 3d printing Okay, like I said, we have a lot to catch up on this week and a lot of videos So what we're going to do is we're going to play these back to back to back So the first one is the 2021 3d printing highlight reel. It's a couple minutes Then we're going to show these really cool 3d printed, um Vulcan Earring Ear things is cool. Elf elf elf 3d printed elf ear Bottle holders and then we have then we have two speed-ups. Yep. So, uh, take away known Pedro In this project we're 3d printing elf ears for our earbuds We were inspired by elf earbuds So we designed our own and made them so you can slip them over your existing earbuds These can fit most earbuds with a similar style We 3d printed it in ninja flex so the earbud has a nice grip when you press it through this loop This features a tapered edge so the earbud stays in place These can be fitted over your ear and wrap around the back Printing these in flexible filament makes them more comfortable and easy to wear We're still able to use the earbuds built-in controls so you can still use them normally We think this will be really cool for anyone who's into cosplay or if you just want to casually wear them You can print them in all sorts of different colors so you can match skin tones or whatever you like We hope this inspires you to try out some flexible filament and make some creative projects for your favorite gadgets Thanks so much for watching and be sure to subscribe for more projects from made of fruit All right, it's time this week sign up. Hi your company. They're up in white planes. Yeah outside of white planes So there are there are next door neighbors basically I don't like people who say upstate when it's many of our lawyers many of our lawyers are up there One time we had to go and uh Visit them. Yeah So this week is uh from janard tools and they make this really really nice Technician you'd be the kind of white. I like the um the the tread on the bottom, too This is very very sweet. Yeah, this is molded. This is sturdy. It's like a tire Yeah, it looks like a shoe. Okay. So, uh, do you want do you want me to click? Maybe I'll click. Um, so this week's iNPI is a Uh technician backpack is a design for technicians and this is like the sweetest ass backpack I've ever seen I mean, this is like you can tell that the people who design this backpack Use uncary tools all the time because all the things that drive you nuts about carrying tools or toolbox They fixed in this backpack. Um, so this is one of the few iNPI's that after like I got it I'm like I'm going to keep this for myself because this is Very handy. So it is a backpack. Um, it's got one big main pocket. It's got two Outer pockets as you said one of the really neat things is on the bottom is this flat molded rubber tire like Base which means it stands flat like if you put it down, it's not going to tip over it kind of has a nice flat bottom Um, but it also is waterproof. So it means if you're outside and you're like technicians working outside in the rain Or you know telephone system or whatever Um, you don't have to worry about your your backpack getting wet or damaged Um inside is like a couple dozen different pockets. Um, there's two multimeter pockets with like, you know, little Velcro straps to hold down the leads Um, there's a screwdriver pockets, you know one for each size. There's um ranch pockets Um, there is a special pocket on the outside for safety glasses There is a zipper pocket in the front for like documentation or Phones or whatever general purpose stuff Everything is like super padded and durable. So you're not going to get poked with a screwdriver Um, what I like is that everything has a spot, right? This is basically a replacement for a You know a tool bench or a toolbox where you're not going to like stick your hand into a sharp pointy metal Saw filled, you know backpack and everything's at the bottom and like a mess. It's like everything has its own place um But it's all the little details That I really like I'll show little details after we Um, we're going to hold up in video because there's like a lot of little things that I'm like, oh my god This is like so cool. It's so smart. Um, one thing I like is yet was designed by this new york company. It's got a Made for life guarantee. So it's like the quality is really good. I'm not worried about it But if there's any defect in manufacturing, um, they'll replace it. So and it's available on digigate for like under 100 bucks It's a really good deal. Um, it's it's a perfect backpack for hauling tools Or I don't know. I mean, I'm sure there's other purposes that this would be useful for Okay, so this is one of the things I really like there's this metal clip That has like a Hard backing and it's designed to like, you know, you have your tape measure And you clip it on and it doesn't come off and it's not like rattling in your bag. Um Tell me when you want me to hold it. Yeah Oh, there's this filter. Oh, this is nice. I didn't even yeah, there's like little slots There's little slots here so you can like, you know, you quickly you're like, I just want to put my rancher screwdriver or whatever pen Um, somewhere really quickly where you're like, I don't have time to open it. You can just put it here. There's uh, 10 slots There's a big velcro piece so you can like Have your own velcro stuff. You can see the velcro here. These are the slots This is nice. This is actually um, most people don't know this but this is for carrying your floppy disc drives Yeah, um Now this is it's it's hard molded and it's got um a little slot But it's soft on the inside because it's meant for carrying your safety glasses Um, so it's protected, but if you feel on the inside, it's got that soft felt And there's another slot and then This zips open and all the zippers have really good zipper pulls which I really like Um, this is just like a holder and then I like that all the um There's like side gussets for every pocket And then the main pocket Oh, just a little note here. This is a nice detail. These little loops here because I even have all these Yeah, carabiner loops. Yeah The two carabiners. Oh wait, I forgot to mention. This is cool. So on the side There's like two pockets for like larger screwdrivers This is for um electrical tape or duct tape or gaff tape. So you open this up And you put the tape in and then you um clip it closed so it's solid, but like you can then Get tape off And then inside there's the multimeter pockets Yeah, so there's like you know multi meter like fluke multimeter sized pockets Tell lots, you know a couple dozen little slots. I mean you can still put stuff in it, but it's really designed for Yeah, it's like I'm trying to think of a good analogy. It's like a really good tool belt. It's a backpack, but also more Yeah And then of course the bottom Yeah Is really good. And then of course it also comes with Free stickers, which is important. They're nice vinyl stickers, too So this is pretty sweet and everything's pad. The back is padded, but it's not all padded. It's just in the shoulder blades so it won't get sweaty And Yes, there's that card So this would be like a really good of course if you work As a technician, but if you have a friend who's a technician and you want to get them a gift This is a really nice gift to give someone that I mean They're gonna love it because like I'm actually kind of tempted to take this home Like we have a big toolbox and it's like a pain Yeah, so you could fit a laptop in here easily You could fit a laptop For sure I would just put it in a case just because you have all the tools with sharp things The front pocket could fit like a smaller like notebook or like a tablet, which is probably what it's for But yeah, it's a really nice. It's a really nice tool belt And I think there was a few left on digikey because you know hard to find anything on planet earth at the moment But there's some there so go to digikey you can check out the short year old there or the ID As well and that's this week's eye on MPI Sorry, but wait, there's more. I forgot. There's a video. Did you want to play the video or should we send? Yeah, sorry Let's play the video So excited No, actually, there's not a video. Okay, there's not a video. That's fine. We did the live demo We did the live demo, but there's a great video on the digikey site if you go to this product page There's a video where they showed in more detail with a really big close-ups of all of the pockets Apologies actually, you know what? Um, I can grab the yeah, I can grab that from over here. Hold on. Yeah. Yeah, let's play it. Okay You know what? It's been a day. Let's pretend that didn't happen. This isn't live. I'm gonna fix it. No, it's fine No, we used to know Hey guys, Ed here from Joan on tools today. I want to talk to you about our bp-100 technicians tool bag backpack This backpack is 20 inches tall By six and a half inches deep and 14 inches wide the backpack features 36 pockets and 12 straps that allow you to Put something in it very quickly and easily and has a two inch wide velcro strip in the front the backpack features a Strap here allowing you to hook up electrical tape and light It has a clip here for you to put your tape measure on it cushion straps and cushion back in the back for added comfort it has a heavy-duty eva foam front pocket to protect things like safety glasses or maybe sunglasses Inside the backpack has 36 pockets Additional spots to put things like small screwdrivers and like you can put them in these pockets as well has two pockets here for your meters Or anything you want to protect the backpack is made of 1680 d ballistic material Bottom here is rugged waterproof plastic. So keep it nice and sturdy and dry and some of those harsh conditions out on job site Thank you. All right, so that's really really my NMPI this week I guess I'll play this thing again. Yeah Okay, ladies before we go into uh new products, let's give everyone the code new year is here That's a code to present off the native first all the way up to 11 59 p.m Tonight are you ready to do this? Yes, let's do it. It's a new new New product of the new year happy new year new products. All right new products first up. Yeah It's a bench. Yometer. Um This is an um alpha of taiwan Right angle 5k linear panel mount bench. Yometer. I know it's a lot But we're actually gonna carry a bunch of different alpha pots And this is like the first one of the series Um, it's a right angle pot. A lot of people use these and stuff like synthesizers and mixers and all kinds of projects 5k linear, you know, we already have a 1k 10k. I think 100k Linear pots from alpha. Um, so we're just gonna add a lot more. So starting with this 5k It's a nice little pensionometer. The pin spacing is 0.2 inches. You can use it in a breadboard if you like It's a very fun pot Next up we have what I call the shortest usb-a to usb-c cable This little thing is handy because it turns anything into a trinket If you have a computer with a usb-a port plug it aside and now you can plug a board with a usb-c Socket on it into it and it's like an instant connection because usb-c is reversible You don't have to worry about like what if the board's upside down because it can always be reversed the other way It's a nice little adapter Shown here with a laptop. Yeah, it's a little handy like trinket of fire Slash shortest little usb-a to see adapter, but I think very handy for dev boards where you want to turn them into a little pluggy thing But they don't come with a pluggy thing. All right, and we finally got these as dog. They're here. Yeah Yeah, we got these, you know what they're called like a meditation box or sometimes a prayer box machine Yeah, these are often hacked people will use the cases or they um Do a circuit? Circuit bending circuit bending. Thank you on the After I said, I even took a photo of the uh pcb on the inside so you know what you're getting or you can meditate to them They are kind of cool We all needed that next up. Yeah, we definitely all needed that. Um, this will help you relax next up. It's the Cp 2102 friend. This is an update basically for our cp 2104 friend Which was an update of our ftdi friend Basically, it's a usb serial converter chip on a breakout with all the pins on the side broken out And then the end is like an ftdi cable end. It's it's basically this power ground data rts and cts combo like six pin connector That's often used in dev boards that need a usb serial converter and maybe a couple control lines But don't have that built in So the cp 2102 n is the next generation after cp 2104 And um, we love the cp 2104. It's a wonderful two megabit per second usb serial converter from sidelabs We use it in dozens of boards However, I know you're about to hear is we can't really get any more cp 2104s They're proving very difficult to find in the shortage Um, but we haven't able to get cp 2102s and so they're almost but not quite pin compatible Um, and for that reason we wanted to start with making a breakout because this is usb c One thing that's different is that it does have um up to three megabit per second not two megabit per second So it can't go a little bit faster than the cp 2104 The onboard e prime can be reprogrammed. Uh, whereas on the cp 2104, it's a one-time programmable So there there is a purpose for having two different breakouts for this board, but Basically, we're kind of trying to get this out to Have an option for people who can't get the cp 2104 And also to um experiment with this chip before we do a swap out of all of our other breakout boards From the four to the two that said it's a perfectly fine ftdi replacement and it's got usb c Uh rx and tx leds. It's got all the pins broken out. So if you need all those, you know weirdo Modem controlled lines like ring or um dtr or Uh, uh, let's see what else dcd, you know, you need those pins this breakout has them. All right, next up Next up is um by request a lot of people asked us to make a mcp 23017 breakout now we carry the chip for the mcp 23017 and honestly I've just been using the chip all this time But I do see the benefit of having a breakout where you know, the pull-ups are set up for you and there's the capacitors and And you know everything's kind of aligned quite nicely. So this little breakout has an mcp 23017 It's a 16 channel gpio expander That you can control over i squared c. So it has 16 GPio labeled a zero through a seven b zero through b seven And each one can be an output and it can drive or sink 25 milliamps of current So it's good for leds and stuff like that. It can also be inputs And the inputs can have pull-ups enabled so good for buttons as well So it's kind of like a nice general purpose GPio expander when I think about the mcp 23017 is it's like kind of old like it's a well established Known chip there's drivers for it all over the place. It's used so often Um and this breakout is semi qt compatible So you can plug it into i squared c very easily on the bottom are three i squared c address jumpers And so you can have up to eight of these on one bus. They use I think address 20 ox 20 through ox 27 It's gonna have lots of gpio, but it's it's a nice just reliable non weird gpio expander a lot of gpio expander has some weird thing going on this one does not it's really Normal so it's a it's a nice Easy 16 gpio plug-and-play with i squared c all right next up big deal stars show tonight besides you lady Ada our team our community our customers Everyone hanging out in the chat tonight is The first the last part we manufactured in 2021 and the first product We're releasing out of 2022 is the esp 32 s2 tft feather So we basically took a 1.14 inch color tft display and slapped it onto our feather esp 32 s2 to give you a Wi-Fi microcontroller board based on the esp 32 s2 with native usb Two uh megabytes of ps ram four megabytes of flash It's got a lot of capability a lot of speed and it's got this color tft display and You can see I also have a little neopixel up top and a stemmy qt port so you can plug and play i squared c reset and boot button It's went through a couple different redesigns due to part shortages and et cetera et cetera Um, but you know if you want something that's just ready to go. It has a display Um, you can even use the you know the boot button as an input So you might be able to do even some simple projects that just need like one button Um, and a display and and i squared c you know plug for external sensors or go to the other hand expanders Let me see if this um Okay, so here you go So The demo I will say it's like oh you have a battery. I don't have a bad the um There's a battery monitoring chip So it in my oh and you have it plugged into a an actual plug thing now. I know. Yeah, there you go Okay, that's nice and sharp um No, no, what happened? I think I pressed something Hold on live demo could be my fault because I um I had moved the power supply over there. I think yeah, sorry about that. Hold on. Let me um Just give me one moment. All right While Lady Eda is uh getting another cable thing here. Yeah, I think that's my bad I had to move stuff around folks. So while we're uh Waiting Admire the photos. Oh, yeah, you don't have a cable Everything everything's been moved. We did a lot of cleaning but um I think we're gonna I think we're gonna stick with the photos then let me stick with the photos and um Actually, let me just go to go to the overhead so I can point out things Apologies, I think I unplugged the uh the usb cable. Um, okay, so I've got usb c uh battery input and you can see here's the stem acutee port um, you can plug in vertical There you go. Um, you can plug in uh vertically so you can have i squared c um sensors and expanders Reset and Reset and boot buttons color tft display. It's all feather compatible. Of course, you wouldn't want to plug a feather Um on top of it like a feathering on top of it But you could use a doubler or you could stack this on top of I'm gonna try this other I think Something I think that power supply is dead because the power lines it It's okay. It happens. Um Yeah, everything everything got shifted around here On the bottom we've got um an esp 32 s2 mini with four megabytes of flash two megabytes of ps ram All the passives for monitoring the battery. There's an lc 709 203 um And that's a i squared c ultra low power battery monitoring that does like Voltage and not cool. I'm counting but it like kind of tracks the voltage You just tell it the capacity of the battery and it'll automatically um It'll automatically tell you the percentage and voltage of the battery So you can like track the percentage and not have to do the the math to convert like 3.7 volts to whatever And there's also a second regulator The second regulator is used to um Disable power From the i squared c or tft display so you can do like ultra low power usage because I think that could be You know more people are trying to use our boards for low power and I thought I had time with this one to to because I had to redesign it doing Due to the component shortage um So you can turn off the tft power and the power to the i squared c port and get down to like 82 100 micro ampere Which is about as low as you can get in deep sleep when using an esp 32 s2 And still have like, you know the regulator and then of course in A lighter sleep like a sleep where you want to We zoom execution. I think it's about 1 milliamp So overall pretty Full featured boards. It sounds like the most stuff. It's uh double-sided. Um, so again, you know, you you don't want to put a Feather on top. I recommend like a doubler or something with this if you want to add More hardware, but this is also great for a breadboard because overhead You can use on a breadboard and have the tft display Um, and um, you know plug it in and it'll the the height of all the components on the bottom isn't higher than The header spacer. So that's kind of what I recommend it to be used for Um, but otherwise it's basically just like a feather esp 32 s2 with a high speed tft display And for circuit python, it's great because you'll have The wrap will show up on the tft when you plug it in And that's new products All right. Well, guess what? We're gonna do some top secret Things ran a little late tonight, but I know we're not gonna stop. We're gonna get you done Yeah, so let's do top secret and y'all can load up questions over in the uh discord chat because that's where we do The question and answers. So uh, first up, I'm gonna do a couple of things. Yes. So this is the, um logo for the Floppy project we're doing right now. It's called data fruit floppy. We'll see something but uh the logo If you look close, this is the back of a floppy. Floppies don't have two hubs and spin around but uh a rabbit does And then these are ears. I like logos that, um Look like something else like the fedex logo. There's an arrow in it And then you can see there's this like a couple variations and stuff like that and for those who know me A little bit of a secret You love monocle logos. Well, not only that But the hackaday logo was almost a floppy That was going to be like a rabbit or with like skull stuff Yeah, and so it was going to be like a rabbit skull with like wrenches or something like that. So that's the hackaday logo I did and uh, you could see there's like, you know, I have a style of the thing and then this is uh Bruce our designer uh worked with me on this and it was uh, it turned out good It definitely looks like like the bunny and the skull are best friends. They're friends Let's hang out, make coffee together. And so then you were showing off these things. This is the super duper floppy Flippy flopper. Yes. This is um, a little breakout board to A standard floppy 34 pin connector and also a 26 pin Um surface mount connector for laptop floppy drives. Okay, and then you had another thing This is just a little feather friend. This is something that's going to make it easier for me to do Um projects with floppy disks because I can plug in A feather without having jeweled a wiring. Do you copy that floppy? this is um Important that when you make a package for a floppy disk drive that the The schematic symbol muscles like a floppy. It's the rule and like I actually spent a few minutes Also made a breakout on request for the drb 2605 Revisited um, and it's a bit cesp 32 and um finished routing an rp20 40 metro airlift All right, and that's top secret All right, so don't forget go over to discord aterford.it slash discord join all 32 000 of us And uh, we're going to answer your questions. There's a couple lined up already Okay I hope it's not why did I just break my power supply because I know well no because we look You know, I'm angry at this power supply move fast and break things. I think that was my fault It's okay. No, I think I kicked. I don't know whatever who knows Um, okay, I put away all my batteries. I was like, I'm going to clean my batteries And of course now I don't have a battery so I usually I have like three batteries in a pile on my desk And of course that's like I want to clean up and now I can't find them Yeah Sometimes having piles of stuff is helpful. Yeah Yeah, we just had to clean we were at start Our apartment is definitely a place where someone who does electronics lives. Um, anyways, so a couple questions that came in Uh, folks say I love all these logos or any chance for a sticker versions in the future. Yeah, so, um I'll send them off. Yeah, I'll do some I'll do some stickers. Yeah, yeah That's the problem. Oh wait, I had one more. Um, oh you want okay, just show this way They're where we're gonna suppress. What else you got? Oh boy. You got pink kb2040 pcb's So I'm gonna make all the rp2040 boards pink I think this is I think because it's like the pig You know, I mean if you have like a little pig snout for the keyboard You gotta be pink since it's gonna be pink. Okay coming soon. Not a question, but uh, It's nice treat for everyone. All right. Uh, thank you for the swd header on the rp2040 metro And then uh, folks seem to like the rp2040 metro Do ganfits offer any advantage thermally and other in low frequency dc such as in a ssr You know, I don't know. Um, every time I've I've, um, controlled an ssr. I've just used like a plain fit. Um So I don't know to be honest and also, you know, I think you calculate Yeah, calculate your power requirements and then, you know, whatever Usually it's like whatever is the rds on or the the, you know, voltage drop of your of your fat, whether the damasfet or jfet or Whatever fat, um And then if you have a high power requirement, they either get a bigger package a heat sink or a more efficient chip Okay, and then, um Well, I think you can answer this question because it comes up. So what what did you use to design? Uh Because it's a common question. What do you use to design this? This is eagle cat. This is eagle cat components editor Yeah, which you can export into, um key cat or cat cat. Yes, either one of this either one of this All right, it's xml. Okay, let's see. I think some folks are typing. So we'll see if there's any more questions Yeah, and then we'll skedaddle Um, oh, how do you get a hackaday skull sticker? Well, I think you could probably hackaday. Well, well go to hackaday.com and email them I'm not connected with the site anymore. I just started it did everything and then now it's theirs Um, they've given away tons of stickers at events and more Um, I have my own little small collection, but they're around The only thing I'd say is I think Events since we're not doing in person events means we're all not getting a lot of free stickers so, um I mean It's uh, ronald and chat ronald if you can't if the hackaday won't send you on Email pt at atafruit. I'll make it happen. I mean like I don't have please everyone don't email I don't have enough for everybody, but you know okay, um Next uh The new atafruit esp32 s2 tft Have you used ppk2 or equivalent to power uh for the power consumption at full power on with wi-fi? No, because I don't care I only care about the lowest power right that's that's the part that you have to engineer to do Believe me you want to connect all sorts of peripherals turn on the tft backlight full power turn on the wi-fi Um, you'll yeah, you'll start peaking at 200 Milliamps easily, but um, it really depends on your situation The only thing I can control um is the lowest power and we got that down to under 100 microamps Good work. Usually people are most concerned with yeah, most people don't ask what's the most power can use Yeah, I think for for microcontrollers. It's like oh like does it have sleep does it have this can I do low power stuff Can I turn on once in a while watch dog stuff? Can I do something and go back to sleep? Um, that's a good question like we should also do the other way max this board goes to 11 I connected it to a light bulb and I think lady either we're gonna be Uh folks like the Color tft. Yep. They're like that. All right. I think you're out. Yay Okay calling it right. That's our questions this week. Well, thank you everybody for joining us uh this week in an exciting show Um mask up get back skip boosted. Um, this will be over, but please stick around for the other side of it I know I'm gonna be good to each other Especially thanks jesse may who's doing stuff behind the scenes in the aid of fruit slack special. Thanks to everyone in the aid of fruit chat I'll say uh, I had a crummy day, but I feel a lot better Because of all of you out there and in the chat and being nice and everything. So thank you. I I forget that No matter how bad things are I can go and hang out with our community online And get those good vibes You know some days it's it's it's hard to remember that Because you know i'm not in front of the computer all the time take a floppy. Okay. Thank you Um, all right, so have a floppy share a floppy. Yeah, so we'll see everybody next week Again, especially thanks jp for doing show and tell this week. Thank you everyone. Don't forget the code is New year is here. We'll see you next week and uh, Hopefully this weekend we'll have some more progress on projects. So stay tuned to all of our blog social and all that and uh We'll post up some more cool stuff Of uh, more making things and sharing it with the world because that's what you do all the way back to high school You were doing that. That's true Some things change But some things a lot of things don't and that's okay. That's fine. The good thing like it's good I think I think I think young lady it would be proud if I could broadcast this and show her What you're up to. Yeah, I think she'd like it. Yeah, okay. All right, everybody. We'll see you next week This has been a native fruit production. I there's no reason I say this by the way. I just like doing it. Um, here's your moment
