 Life in New York. It's ask an engineer. Hey everybody and welcome to ask engineer. It's me lady Ada the engineer with me Mr. Lady Ada on camera control. We're here at the 8 foot factory in downtown Manhattan Where we do all of our designing engineering kidding shipping and more. We're at the factory. This is a real factory behind us It's the real deal. It's not a zoom background. That's blurred and changed. This is not a green screen Bye You want to come back for yeah, I got a jam packed it's actually when we open the files like oh my god There's so much stuff in tonight's show. We're here for an hour with all the news and products and videos and It's retro tech and boy all sorts of stuff including a bunch of fun keyboards. It looks like stay tuned We're here for an hour Let's kick it off immediately since we have so much to get through what's on tonight show on tonight show The code is top sensor 10% off in the different store all the way up to 159 p.m. Tonight top sensor get to 10% off in our store Save a buck or two before you check out and support a 100% woman owned open source hardware company manufacturing in USA All those check boxes of all the things that people say they want in the world. Well, you get to help out Yeah, you get to help out and fuel this machine called the Starship beta fruit Advert live series shows we'll be talking about our show and tell people came by tonight This was a packed show and tell Time travel look around in the world of makers hackers artists and engineers a big old Retro tech section where we show some of our photos from our retro tech that we posted during the week on all our social medias and more From the mailbag your letters tweets comments and more to us and our team Main York City factory footage a look at what goes on here all the time at the Averitt factory 3d printing I'm imp. I new products Top secret we answer your questions. We do that over on discord adafruit.it slash discord or discord gg slash a different joint all 33 plus thousand of us 24-7 even if we're not there Later on tonight because we're like sleeping or something There's thousands of people there at all times who love to show and share their projects and help you out With whatever you're working on all that and more on you guessed it It's asking an engineer Okay, so pay some bills top sensor is the first thing that you should jot down because we're gonna probably show some Stuffing to be like I want to buy that but I want to save some money But when you check out in the store you can Get free stuff lady to what do they get when they start adding stuff to the cart? That's a good question when you order from the adafruit.com store and you get $99 or more You get a free perma proto Has size breadboard. It's a handy thing to use or give lasts a long time to keep it a door 149 or more you get a free stem IQT sensor We're adding more sensors all the time as we've designed more Light sensors and temperature sensors and and QT pies and controllers and all that good stuff You'll get a different one each time if you make an account 199 or more you get free UPS ground shipping in the Continental United States. It's trackable It's insured it comes in a brown truck that looks just like this, but a little bit larger It's free ground shipping when you order $200 or more. Okay, we do a bunch of live shows We do these every single week so the live show that we just did right now this week We were up on show until we had a bunch going on. Oh boy, and we had a lot of adafruit team members We had a bunch of stuff going on But you have a particular project that I love the skull keyboard because it's a keyboard and it's a skull How can you not I mean it's the two best things skulls and keyboards It does combine a lot of the things that we like here in circuit python black shirts skulls skulls things like that Keyboards keyboards, so check that out and mention the skull Yeah, and it's a really neat one because the user circuit python and I think this one was based on RP2040 and It's kind of a remix of a lot of the keyboard projects. We've been seeing yeah, we also saw a cool project that used stemma some QT That someone had made a kit and then they added stemma this year. Yeah, and then there's a neat lamp Where you get a lamp with the lamp Put your hand kind of like a light there a man Yeah, let's show it some music stuff and shit some floppy stuff Kevin from did you key come on? He had a skateboard. Yeah, and Scott showed Some of the USB host stuff and there's a deep dive come up. We'll talk about that in a bit But anyways action-packed jam packed. I wish there was like 12 people. Yeah, but some of you Yeah, someone in a chat said I wish show and tell was longer us too We were talking to someone and they said oh like, you know, what's the what's the most challenging thing? Running a company and it's just time like we like if it if it were possible We'd love to just do like 24-7 electronic video shows But we have to make electronics and then do video shows about electronic So you have to figure out the best way to do it But anyways, we do show and tell every week so even if you're not able to get on the show One week don't worry. We've been doing this for like over a decade So unless something dramatically changes, we're gonna keep doing this even a pandemic didn't stop us We did a full hour during the pandemic because we were all freaking out and we all just wanted to talk to each other So we're like, why don't we show the things we're making? It's like a hacker meetup every week because this was scary so anyways Desk of Lady Aida, that's what we do every Sunday Lady Aida, what was on Desk of Lady Aida this week part one? Well, I showed off a couple designs that are working on first up the Feather ESP32 v2, which is this week's new product. We already sold out. I also showed a raw LCD display GPIO toggling and The Winamp MP3 player demo that foamy guy did for the learning system. We also have the great search This is where Lady Aida user powers of engineering to find things on digikey.com Which is really useful because global part shortage. What did you show how to find this week? I know because I'd like to restrict myself to only finding things that are in stock this week I found this is something I was I've never looked for before but it's an I squared C LCD segment driver So oftentimes using microcontroller that can do LCD segment driving But maybe you want to use like a Wi-Fi microcontroller like an ESP32. It doesn't have a native LCD driver Pick up an external I squared C1. I found a lot of good options here. So check out that video. Okay on Tuesdays we do JP's product pick of the week we broadcast live from inside the product page also at some point we probably need to do a like Pi portal or like a book of thumbnails JP is pushing the state-of-the-art for for YouTube algorithms The history behind this is Google had told us that you know if The more word like a swimsuit and put that on the thumbnail You know the algorithm would pick that up and there you'd have more views on your videos And we're like that's a weird thing to suggest So what we decided to do is have like super freaky Thumbnails and so far so far it works We think we haven't asked JP to wear a swimsuit yet But we do this every week from the product page and on the product page. You don't even need to Use a discount code. It's automatically there So we got this idea from some of the international giant online e-commerce Empires Ali Baba does this Taobao does this where they broadcast live from inside the product page Yeah, and as they're running out of stuff the people that are on video They're like, oh, let me go get more and let me let me talk to the community and they're like millions of people watching this Yeah, we have a few hundred. So anyways, here's this week's highlight from JP There it is my very own the MCP 23017 breakout board. This is a 16 IO expander so you can do inputs and outputs you can add up to 16 switches or buttons to your project You can add up to 16 Outputs such as LEDs has the stem of QT port simply plug that in and all of a sudden This little board that doesn't have that much IO built onto it grabs an extra 16 ports You can see it underneath this board here. There's the MCP 23017 with eight wires running to LEDs and resistors on the top row there and eight wires running to these switches here It's the MCP 23017 16 IO expander Okay, and then JP's workshop is Thursday tomorrow Here is a preview of some of the things you're gonna see this is a phone project Lots of retro tech going on now. I think fun. Yeah, those are super fun. Very tactile and then we'll see you on the other side and On JP's workshop, we also do a segment called circuit Python parsec where you learn a little tidbit of Circuit Python and a bite-sized parsec take it away JP for this week's highlight for the circuit Python parsec today I want to show you how you can use shapes and fill in display IO on circuit Python in order to draw objects onto a Screen so if you look here what I have it's a feather M4 Plugged into a feather doubler with our OLED feather wing and one of the cool things about this feather wing is it has these three sort of general-purpose buttons that you can use connected up to pins 9 5 and 6 and What I'm gonna do is simply press a button to make one of these three little squares appear In fact, I can turn them all on all off in combinations of those if I want the way this works if you look inside of my code I've got some libraries to import including the display shapes rectangle library Then I set up the screen and I'm using this BG Which I'm just calling the background is a rectangle that's at the 0 0 position at the full width and height And I've outlined it with white even though the fill is black Then I make these three shapes each of these are initially filled with black as well I set up a button for button presses and then in the main block of my code here I check and see if a button is pressed of those three when any of them are pressed the Associated box will change its fill using this command shapes dot fill and then in this case zero X F F F F F F which is white When the button is not being pressed then we return it to black And so it's a really quick and simple way to draw shapes on and off of the screen inside of circuit Python using shapes and fill and that is your circuit Python parsec all right, and then Friday is the Second-to-last deep dive before Scott's going on break. So tune in. This is the USB host one He showed some of the stuff on show and tell so if you want to see some of the inner workings of circuit Python And how we're doing things especially now for some neat stuff with Raspberry Pi Check it out. So that is Friday's 2 p.m. Pacific 5 p.m. I am X An XP series too. Yeah. Yeah, and then we're gonna do RP 2040 and then we'll add USB host for both Okay, this is the secret. Is this like breaking? No, no, no, no big deal No, because you showed it off on the show and tell okay, I mean if you watch show and tell so now it's now now everyone's gonna know No, I know this is this is how we're more stars Right no, yeah, and is it gonna be possible for folks to try this out soon Um, I think I think Scott's gonna he's gonna be adding it And then if you have like a teensy or you maybe you could use you could use like a teensy Yes, I think that's what he's that's what he showed on the show and tell that's not a secret No, I know I you know because people see it and they're like, where is this? I want to try now It's coming. Okay. Okay time travel in the future. There'll be chips So just a reminder speaking of parts shortage, so our ate a box will be shipping We're gonna be shipping it seasonally. So what we decided to do is to try and it Pick it to a holiday, which is nearly impossible now. We decided well, let's do Seasonal editions. So this is winter spring edition It'll probably technically be winter somewhere, but we hope to be shipping this out in the next 32 60 days So we're full but go to ate a box calm and sign up And if there's people who are leaving or putting your subscription cause You can get a notification and sign up So we have thousands of thousands of people so we can't add anymore because there's not enough stuff on planet Earth So if folks do decide to pause or cancel their subscriptions, you can jump in. All right now back This one's a little different this week instead of it being an email or a comment or something This one is a tweet that we saw and it wasn't exactly Addressed to us, but kind of close and so I grabbed this one So this is one of my favorite Authors, she's really cool comics about programming and stuff and she said what's a programming thing that used to be hard within the last five years This has become easy like before you had to be an expert now anyone could easily build something useful and space enthusiast nailed it and said Embedded devices before you need to buy an expensive kit and get lots of really complex software now to make a tiny custom device You can use Adafruit circuit Python and one of their boards plug into USB edit main dot pi with a text editor reset and done So not only were they able to explain how easy it is now they got it into you know 140 characters they wrote it on their phone and they were able to talk about something that made their lives really easy So this is like, you know when you work on stuff it took years for us to make this that simple And it was neat to see all the things that people said were still hard and the things that people said were Easy so thank you so much space enthusiast Hendrick for the little shout-out and more if you have something nice to say Social media. I know it's not used for that But you can use it for that Just tag us you can also email supported Adafruit If you have like some good feedback for us or you can put comments on our videos and more but we read everything So there's humans on the other side So when you have something nice say we call these hug reports internally to not like physical hugs instead of bug reports We say hug report And so people like hug report so and so help me with whatever. So anyways, all right, let's do some retro tech okay, so Every single week pretty much every single day Pretty much seven days a week. We post a glimpse of the past And a lot of this because I have to say why we're doing this a lot of this is to help people Especially people that are just getting to electronics people that are just using Things to prototype things that are people that are doing using our stuff in particular for product design It doesn't just have to be a black rectangle There's lots of designs you can explore yellow sphere. Yeah, and there's lots of mistakes in the past So you don't have to repeat either. So it's a combination of the two. So this was a Keyboard that the Bloomberg terminals had and we had taken these photos a while ago But when Bloomberg was running for president Everyone if everyone just was angry about everything So I just decided to hold on to these photos until now because I didn't want to get in a fight about like should he be President or whatever. So this is a Bloomberg terminal keyboard that they're not really that easy to get because they're usually attached to like a $20,000 terminal. So this one was like a sound thing inside of it Here's all the cables that plug inside and plug into it. So it was lots of different things was microphone speakers and Pretty much everything the speaker grill is really where it's out there. So kind of neat Look at that big enter key. I mean, that's like the biggest enter key. It's chunky. That's like a good buy Buy it sell it. Yeah, so other retro tech that we wanted to show is some controllers that You just don't see them anymore. So this is the space orb It's a PC controller parallel Porter cereal They made some game controllers too, but you kind of twist this ball at the top and it's a six degrees of freedom six top controller and They're not around anymore But this is a you know explorations in user interfaces this is a cassette tape player But it's for a TRS 80 so you would use this to store and then read your computer programs And I thought maybe Lady Aida could tell everyone like how exactly was that possible to store? computer programs on an audio cassette it was like basically like a modem like the beeps and the tones like I think the the zx spectrum did this TRS 80 and you would be for Loading programs, right? You wouldn't I don't think you would save To it, but you could duplicate the cassettes, and then that's how you would duplicate a program Well, I guess you could you know like the correct the code and then you could Write it, but I don't know if you I don't know how you could handle multiple Devices, but it was of course very slow, although it's ironically tape is still used nowadays for archival purposes because it's so dense Okay also a retro tech this week. This is one of my favorites. This is the Quick cam the connects quick cam and they later turned to Logic tech and look at this series of cables took it up. It's I think 256 gray scale And the other neat thing is it came in a box and a rebate and hey I got a rebate with stuff back in the day and even the box is interesting. So their theme was this like triangle that the Web cam wasn't really even called a webcam at the time. I think the use see you see me. Yeah, it was just called like a Camera, yeah, I know Yeah, it was it's called a quick cam and this was one of the first ways that now every Computer and every phone has a camera in it But this was like one of the first ones is a big deal and the design is really interesting and weird that the base of it Of it was a triangle and the packaging reflected that you could rotate it within the triangle. That's why yeah That's the very clever and you know a lot of things that came out back in the day they they had to educate all of us about like what this is how you use it why you'd want it and You just don't see things like this as much anymore. So this was in the 90s. Let's keep going back in time. This is from 1972 This is the Panasonic ball. It's a it's a ball. Yeah, it's a Panasonic ball Panasonic had some really freaky cool Transistor radios. This is the r70 and I think it was called Panopet. They had a whole series of things and You would use this as a radio they love spheres and yeah And you would hang it somewhere was like a ball and chain radio was called Panopet and the 70s because of the year And you would tune in the radio stations and more You know sometimes now you see some like interesting music players that are that are not just like you know Like an iPhone looking thing and then this is a preview of something we're gonna take photos in this is a Star Trek Deep Space 9 CD Player music Yeah, and you could see some of the things you would listen to it on your Starfleet issue Headphones and you would look up things about Star Trek on your desk With your Star Trek and Cyclopedia the all-cars interface and then you would use the official Star Trek cassette tape adapter to play this in your car and Here's what it looked like Kind of cool killer. All right, and that is this week's retro Yeah, stay tuned to all the social media channels and more we do this every single day. That is a lot of retro Yeah, all right. It's Python on hard wartime Okay, so what's going on this week in the world of Python on hardware? Okay? We have over 256 circuit Python boards and to do and we've passed this a while ago but we now have this graphic because we're clever and That's the why don't you explain what these letters and numbers mean? I will 256 okay, so the cool thing about circuit Python is that anyone can contribute a new board In fact, we have like new boards almost weekly basically people can design their own hardware and submit support and They do it automatically and we approve it and merge it in and then we can download you can download your firmware That's updated automatically for you at circuit python org slash downloads and we recently got over 256 boards and 256 is a magical number because it's the maximum number that can fit into an 8-bit Number which is how computer stored data and so like kind of when you get over that you're like it's a big deal It's like when humans turn 100 when your software project turns 256 same thing So we finally got to 256. I think we're actually up to 260 something by now With more boards coming in and it's a good sign of a healthy Community because it means people are submitting Their designs people are trying to add boards and the most important thing is it's not just a two-foot boards They're circuit Python. There's Pimeroni. There's seed. There's other consumers a different board Sorry, there's more boards in our native board by far which is like that's the sign of success We think is this like cool like if you're interested in doing electronics and running a business or making hardware and Not having to reinvent everything over and over you can just build on top of circuit Python and Every time there's an update circuit Python your board gets updated. Yeah, anyways Circuit Python 720 has released Canada zero. Is there anything in this release that is super interesting that folks should 7 7 to 1 RC Sorry 710 RC's whatever and the previous version was a little bit of a mistake So basically just make sure you've updated to the latest There was a little bit of a number confusion But the most important thing that I think people really dig is that we now have board dot stem underscore I2c which means that if you have a board that has a stem a QT connector and you know, you want to make sure that your Your iSquad C sensors connecting through that you can now use this like short happy name And it was also a community contribution. I can't remember top of my head who the contributor was So check that out and then Of course are adding ESP 32 S3 and C3 support including BLE more to come with that a lot of cool BLE news coming up soon Okay, I'm gonna save the win-nap thing for my little highlight We have a ton of projects one thing I wanted to spotlight is the Python software foundation has a couple cool jobs Do check that out if you're interested in helping out on how they can deploy accounts in pi pi They have a couple of roles that open up We try to help them out with things The projects of the week you could see a bunch, but the ones that I'm gonna pick this week is Little bit of a reminder the circuit Python show will be coming out on March 1st That's next week first guest will be catnig here is a very cool circuit Python based Project using raspberry pi circuit by bond. These are blinky eyes that are also disco balls I'm gonna show that I think I saw these at the Elton John show and then The project I wanted to highlight this week is there's a lot of folks who remember Winamp who didn't Download all their files from Napster and use one amp. That's right a lot of folks did and Just for the one guy out there who doesn't like Winamp now because we're playing around with it with Python This is a beginner project that we want folks to try out so it doesn't support everything that Winamp does not yet But it's a great beginner. Yeah, and so we put this thing on there We're like by the way this is to get you started so you can remake Winamp you can download the skins you can convert them and then you can play and mp3's and and But it does have the schooling text. Yeah So one of the things that we decide to do often is here's a project that's easy to do that can get folks started It's it's not Everything it's not everything and it's not a thing that you need to join and you're gonna spend your entire life doing You can get started and play around with it. So Tim Fomega did a really good job I want to do a hug report and shout out to Tim But this is really neat because this is kind of exactly what I wanted Which was like I just want it to look like the Winamp player. I want to be able to mess around with some old skins. I want to be able to play mp3's which I still use and I want to have that nostalgia And I want to maybe make like a little physical holder for it So I can make my own music player that all it does is music it doesn't go online It doesn't do anything just the music so that that was the goal of the project So Tim's gonna explain it in this video But very cool And if you're interested you can check out the guide and then check out the collection of the thousands of skins You probably had these on your computer in the past and you can remake those and play your music again Hello everyone in this video. I'll show you my latest project for the pie portal. This is a Winamp mp3 player This runs on the pie portal. You can fit loads of mp3 files on the SD card Which is plugged into the back of the pie portal Store your playlist files as JSON right on the circuit pie drive So you can add and remove songs from your playlist You can keep multiple playlists and swap between them simply by editing the files There are three invisible buttons on the interface of the pie portal The whole top half will pause and resume the music right now My microphone is not capturing the music, but I have just started it to resume and you can see it's now counting up there So I could press it again to pause you can also use the bottom half of the screen to go to the next and previous track So if I touch in the bottom right we will advance to the next track the playlist at the bottom will update the current track Title on the top right will update and we could resume to hear at the second song now same thing with the previous button the Probably the neatest thing about this latest project is that you can actually customize it So what I have right here is the base Winamp theme But you can actually browse through hundreds of different Winamp skins on the Winamp skin museum Find the one you want download it by right-clicking it and choose save image as Go ahead and save this file and then you run a conversion script on your PC copy the resulting files to your circuit pie drive and Then you just have to change these two variables here in the code pie to update to your favorite new custom skin So grab your pie portal load up all your favorite tunes. Thank you for watching So if you ever want to design your own music player have something that's not internet connected Just play your music and play around with user interfaces and more you do that with Python and you can take a trip to I forgot the name of the site that someone could put it in the chat I think it's like when amp skins.org or something. It's the Winamp skin museum. There's a couple of them He's gonna win at skin museum. Yeah, and you can get this newsletter every single week Over on Adafruit daily we have a completely separate site because we don't spam people we don't harvest emails We don't have that pop-up thing that comes on a website when you buy something from us We don't subscribe you to newsletters So we went above and beyond and we have a whole separate site So if you want this newsletter delivered to you, that's where you do it All right We're an episodes hardware company Although although I had a thing that I was gonna say so we were corresponding with an organization and You know you and I talk about open source hardware because we get asked the same question a lot One of the questions is was the business model sign open source hardware company? Why should I do open source hardware? Why are you worried about people cloning your stuff? Why should I get my open source hardware certified and I think I finally figured out what we do We do something different and we just happen to also do open source hardware secondary effect Yeah, it's it took me a while to figure this out like like almost 20 years We're actually doing I know something to find yourself. You know, it's a quiet journey. You end up back where you started Yeah, there's a there's a quote. I'll change the a person Who steps into the river? Isn't the same person each time and the river is different either when you think about it The water is moving things in the river itself are moving. You're different So, you know when I was thinking about this We just happened to also do open source hardware and what I'm what I'm trying to do is figure out what we what we actually do I think we're a cause and A force of nature that helps people learn things and we share electronics we share Code and one of the outputs of this idea that we're always gonna give give more In this world is it it just happens to be open source hardware And we have things like guides we have two thousand two hundred and twenty six of them But I think the next time you're asked or I'm asked like what we are I don't think I'm gonna say an open source hardware company I'm gonna say we teach people electronics and sharing and you know, hopefully good things and One of the outputs just happens to be open source hardware That's what I'm thinking The step of a thousand miles with one step. So we have 2,626 guides Yeah, 2626, you know this week was 22222 as well. Yeah, it's a Week of numbers not to choose this week. I got three new guides this week We've got the floppy drive case for three and a quarter and five and a half inch disk drives from known Pedro I asked them to make this because my drivers hanging out like all jiggly doggie all over my desk I thought it'd be good to protect them from accidental spills and dust Because usually they're inside cases Power cases and they don't have they're not exposed to the outside world I've also got from catney a guide update for the ESP 32 s2 tft feather. She's adding more Tutorial pages on using the tft and built-in sensors people have been asking for that and of course from Tim C We've got the now famous pie portal win amp mp3 player guide Turn your pie portal and he'll be updating it also for the pie portal titanium. Oh, perhaps You can turn it into a very simple mp3 player. Yeah, and Seeg River has a really good point with this is the win amp implementation is a really good example of how skins can Be designed and coded for other projects, too So that's like kind of the point It's like everyone sees these win amp skins and it's like well What if you wanted to make that work on this and it teaches you that so that's why I think these these projects are a really good idea Someone in the chat said is there any? Clone you know like hardware that you could just like run win amp skins on not yet But this is one step towards that. Yeah, so that's kind of cool. Okay. Let's do some main New York City factory footage And it wouldn't be a food factory footage Unless you saw a view out our front window now so This is the Disney headquarters are building across street This used to be a view of the skyline and the water the nature Hudson River. I don't know about that birds so This is what we have now now. It's yeah, okay Let's Talk about some 3d printing. I have a thing. I'm gonna talk about Man this week is full of things. I'm gonna talk about a thing and just to give you all some ideas of What we're trying to do so we emailed the PR folks at MakerBot because We saw that when you go and try to download the files so if you go to thingiverse.com slash adafruit and You try to download the files now and some things change what's changed Well, if you have an ad blocker on it says hey, you can't download the files if you have an ad blocker on You see this on all sorts of sites around the internet. It's new on thingiverse and So if you go to the website and you don't have a web blocker on or if you you know use incognito mode or private mode It says okay. Well cool You're gonna download stuff now And it looks like they're getting ready to have these like this ad stuff and then there's a ad for try Amazon Prime 30-day free trial so Comments aside about business models and how to do things that wasn't what Thingiverse was when we started uploading our files and so I sent a note to MakerBot and thingiverse and I said hey When did you do this change because that seems really recent? I just want to know so we can do a little blog post and tell our community when thingiverse started doing this and then What ad network are you using and is there a way to report? Potentially bad ads problematic ads or malware this happens on ad work all ad networks all the time One thing that I kind of know that happens with ad networks is someone's gonna go and be told Oh, hey students go to Thingiverse and download these files They're gonna click the thing and it's gonna show an ad that's not great and a teacher is gonna say hey Defrute just so you know your your stuff is next to not great ads and I wanted to ask Thingiverse is there a way to Report bad ads or something we post our files in all sorts of different places because that's what one should do We like to put our files in one place and then Syndicate everywhere. It's a good strategy. What was like it was like I'm already said it was Plus it was like publish once syndicate host on your own site and then syndicate everywhere Yeah, so like we do that. So if you see a photo on our Instagram, it's also on Twitter It's also on our own website. It's also on Flickr because Who knows what's gonna happen and all those other places. It's on Facebook. Don't worry. We also have it on, you know, Twitter, too so We're just trying to get more information and we also It's not helpful to like dunk and shame people. I well, I should say it's effective, but it's just not our style so We're a little weirded out because this isn't what You know, we this isn't what we use Thingiverse for we don't get a cut of the ad revenue. Yeah I don't even think we'd ask for that And so the other thing I asked did you talk to any creators because I think we're one of the more popular destinations on Thingiverse and the MakerBot folks to PR folks there They've always been responsive to give them credit. So I dropped them a note If I need to what I'll do is I'll send them a link to this portion of the video so they can see what you know They can hear our voice We just want to know what's up and like can we opt out of this and like is there other things that we can do because I know what's going to happen as a teacher is going to say there's an ad that's not great Next to your files. What are you doing about it a different though? Basically because they can get a hold of us And we're held to a very high standard. They're gonna, you know Hopefully they'll be nice about it, but I think that's what's gonna happen So anyways, I'm gonna show two videos back to back This is the transparent case for the floppies and then a speed up of a cool 3d printed fish Hey, what's up folks in this project? We're making 3d printed cases for floppy drives We designed and 3d printed these cases for both five and a quarter and three and a half inch floppy drives They're designed to slip over your standard floppy drives without any hardware and they feature an embossed pattern of little Adafruit logos This was printed with translucent PLA filament and sliced with only shells and no infill The transparency is clear enough to make out the internal parts and it looks pretty cool To install just slip the floppy drive into the sleeve with the back end going in first We designed the sleeve with the recess on one side so you can stack a three and a half inch floppy drive on top We think the case gives off vibes from the 90s clear electronics trend Links to the CAD files are available in the description of this video We hope this inspires you to 3d print your next project enclosure in translucent filament and bring back the nostalgia Thanks so much for watching and be sure to subscribe for more retro projects from Adafruit Okay, and if you want to learn how to make all this stuff and more tune in to 3d hangouts every Wednesday at 11 a.m And yeah, anyways, thanks for the good feedback folks. We're like, yeah Thanks for reaching out to Thingiverse about talking about this Our goal is into like avoid ads and do that. Although I can completely understand why one does I just want to know what's up and Help our community make good decisions on where they host our files how to report bad ads Every single ad network in some way has had malware that sneaks in And you know Thingiverse we've all kind of grown up together with it It's been part of this open-source community for a while and a lot of people especially educators Use it to download our files. So we just want to know what's going on. All right. Let's do some my NMP. I laid it All right, so we found out Well, we we knew that maximum integrated is now part of analog devices But we really found out now because we were going to link to the maximum integrated Twitter account And it's like nope gone. So this week's iron MPI is for sure. It's maximum integrated But it is it is it is analog devices Okay, it's both the part number is a max part number So this week's iron MPI is the max three one eight eight eight It's a new high precision high accuracy one wire temperature sensor That's available from Maxim which I think purchased Dallas semi because the DS series was the DS 18 B20 and this is clearly kind of a next generation. So yeah, these companies they just kind of squished together a lot That's great. They're all analog devices now. Congratulations to ADI So again, this week's new product is the max three one eight eight eight It's a one wire temperature sensor, but it also has a unique NIST traceable 64-bit identifier and it has like three GPIO as well and It's it kind of does like a lot of stuff going on there and you know It's a little bit specialty. It looks like it's probably goes into somebody's product like I have some ideas of what that might be But I thought it would be also useful if you have any kind of temperature monitoring That you have to do especially if you have either a very limited number of pins that you want to use for temperature modeling Because like the DS 18 B20 this is a Aracetically powered sensor. So one wire like don't people don't talk about it as much as I squared C I squared C is the most popular sense of protocol right now But one wire which started with Dallas semi and is now owned by Maxim It's kind of neat in that you only like they say one wire, but it's really two wires You need ground and then one data slash power wire and that's half as many as I squared C Which uses for wires and a lot fewer than SPI that can use, you know Five or more because you need power ground and then three or four data lines So you only need one wire and that one wire is used for power and data. You can see the diode inside This simplified block diagram and it can parasitically power. You just need to give it a single capacitor to help that parasitic power So like I think a one micro farad or so is good enough And then all you need is a the ground wire and the data power wire and you can chain as many as you want Which is kind of neat and there's also a special case here where you can use a GPIO pins as kind of pseudo addresses So you can have eight You can have as many as you want on one wire But if you want to like be able to kind of sub address them, you can use a GPO GPIO wires as well I thought you know one of the examples they had in the data sheet for what this could be used for is Cold chain monitoring and cold chain monitoring is something that nobody used to know about two years ago And now everybody knows about because it's how we Trans transmit sorry Transport vaccines around the world vaccines out some of them have to be kept very cold Negative 80 degrees and you want to make sure that that no point do they heat up? So if you have a big box, let's say you have you know a palette that has vaccines in it And the box is maybe a meter by a meter by a meter You want to be able to measure the temperature at every corner so that would be six different sensors and one one in the center and make sure that at no point is any Side of the box get under negative 80 get above negative 80 degrees You could use something like this and you would have minimum wiring like you wouldn't have to pass a long chain of I squirt C cables and and bus expanders around you just use two wires and they all connect Onto that one bus Another thing that's really nice about one wire is it's designed for long distances unlike I squirt C which is You know power ground SDA SCL and some pull-ups and it's really only meant for like maybe You know 200 millimeters You can easily put I squirt C bus on with just a pull-up resistor on 200 meters of cabling Using a cat five cable, which is a lot like 200 meters total That's that's a ton and here is there's some examples of different topographies You can use and it's up to you whether you want to use star or bus or you know stubs and and they have some examples also of if you have a Active driver like they have specialty chips for active driving of ice of one wire. You can go up to 500 meters So, you know a cable like this that would be very tough to do with I squirt C This is a one wire temperature sensor. So This sensor kind of builds on the you know DS 18 B 20 popular series. It's a point two five degrees Centigrade Accurate compared to point five degree and of course has those extra GPIO pins That the DS 18 B 20 doesn't only has one pin for for power and data and then and then ground so You know it could be good for battery packs for cold storage for data logging ultra low power temperature and GPIO control there's also a handy dandy a valve board available You can use from maxim which has a sensor and then an I squared C to one wire converter If you haven't used one wire, do you check it out? It's very reliable It's really good for temperature sensing. There's a couple other, you know, there's e-prom and I think Microchip also has a secure element. That's one wire as well. So it you know, it is available for multiple Different manufacturers and it's great when you really just want, you know One wire simplicity and long-distance support for sensing Okay available on digikey You can actually get it. It's in stock. Yeah, it's available right now both the valve board and individual chips There's a short URL there is the digikey ID and don't forget maximum graded is now part of analog devices And that's right on MPI Okay, well, we're gonna do new products in a second or so, but don't forget the code Tops sensor or 2f sensor time of flight sensor or Tops and soar any of those work, but you just have to put the letters in the right order All right lady, are you ready? Yes, okay No, okay, what's up this week lady Ada? Okay, first up. We've got a 1 millimeter 26-pin FPC cable. I'm gonna be using this for some floppy stuff. So just hold on tight to this You know came in before the floppy stuff did But that's what we use it for it's floppy disks floppy disk drives used in laptops use this cable And I wanted an extra Next up we have a gorgeous even the people who are fabricating it were like this is a really good looking TFT screen. It's a 1.47 inch 172 by 320 pixel IPS display using the very popular and well-supported st 7789 chipset It's a very easy to wire up and use whether Arduino circuit Python libraries You just set the resolution to 172 by 320 and it's you know extremely high PPS pixels per square inch. I think it's 220 just I think the the highest density we've got Are very close to the 1.3 and on the back. It's also got an iSpy connector So you can use it with a breadboard with the breakout pads It can be used with three or five volt logic and power Has a micro SD card slot if you want to store images or animations on it as well and share with the SPI port And then the iSpy connector makes it very easy for you to wire it up if you want to put the display far away So a lovely little display will have its big sister the 1.9 inch in the store shortly All right. Did you want to show it off? Yeah, I can show it off Get real close because it's real small. Hold on. Yeah, let's flip it around. I Like that we have really good photos of our stuff. However, I do like that We were able to always do live demos of our stuff because I feel like that That means it actually is kind of easy to use of life It does mean something a little different Because you could see it turned on like yeah, you know stuff over video cameras and web cameras and all that So it's very beautiful it's got that round wrecked Oh people ask round rectangle displays are made by deleting pixels or isn't like some weird like radial squishing So, you know at the beginning and you see it display some text The display gets cut off. Yeah, so that's how it works. Okay. So anyways, so here's the beautiful photos are all good We have we love our beautiful photos, but I'd like to like demonstrate. Okay, next up Okay, next up we have a new time of flight sensor. That's the TOF sensor for the code Which can get 10% off this sensor if you're watching this live. This is a new time of flight sensor from ST This sensor, they you know, they've done the VL 6180 and then they went to the VL 53 L0x and then the 53l1x and those got up to like four meter distance. This one is a shorter meter distance This is 1.3 meters distance, but it's good for closer up According to the data sheet it can do as little as one meter one millimeter away So it's good for closer measurements Because I can you know the other sensors kind of can't do less than one inch or one and a half inches away And this one can do less than that And it's got Arduino library support right now. We'll be working on circuit Python library support So if the text description says it's got it by the time you watch this video, it does but as you know This chip just came out and we got it real fast into the store Using the Arduino library and thought I could show it as well Another live demo. Yeah, and you can see the little sensor. It's kind of nice and you can see it's Got me moving up and down That works, huh? That works it does work and it doesn't display if I'm too far away, so It's still time a flight sensor. You know, I think this one is good if you just need Closer Measurements, you know, if you don't need up to four meters if you only need one and one and a quarter meters away Then this one will do the job very well. Okay, and then next up It's a revision, but it's a well-loved revision people really enjoyed the pink feather RP2040 that we put into the shop as a freebie over the winter holiday and We thought let's just make all of our RP2040 boards pink and so now our classic 4884 feather RP2040 Same exact design, but now pinker not black pink with black silk screen. It looks gorgeous And if you order them now, that's what you'll get. Yeah, so thank you everyone who's said more pink boards Pink pink pink. You said it we listen and then 2040 last week this week the feather All right, and then the star of the show tonight besides you lady or community or customers or staff running things behind the scenes and more is the new feather ESP 32 V2 this is a really big fresh upgrade to the feather ESP 32 one of our most popular feathers Because of the chip shortage, I can't get CP 2104s anymore That's the USB serial chip and so I have to update to the CP 2102 Which has a slightly different schematic usage and so it was like well I got to go fix that up to revise this board so I can keep manufacturing it and then before you know it I kind of like remodeled the whole thing so the whole board has gotten like a huge update Which is great. So let's just stop here because I can I can point at it while it's nice and big On the right there used to be a war room module and that's the Pico module The Pico module is an ESP 32 with eight megabytes of flash and two megabytes of PSRAM So that's twice the amount of flash and then extra PSRAM that was not available on the original ESP 32 That's super handy if you're buffering data or you just want like You want to have a camera interface or a buffer a display output? Read large JSON files parse them that PSRAM is so handy and the ESP IDF and Arduino is natively just you know map that memory in and so you can use it It's not as fast as the SRAM, but it's great for again large data buffering To lower left of that there is a new Neopixel on it The ESP 32 did not have a Neopixel now it does and the power pin is on another GPIO So you can go into low power usage and that's another thing. We really optimize this feather for better low power support so the Neopixel can be turned off and then there's a separate LDO right above it for the stem IQT connector That's the kind of yellow forpin connector above that you can get down to 70 microamps of power draw while in deep sleep for the ESP 32 which is pretty good because You know you can wake up from deep sleep with the RTC on at any timer interval you'd like The stem IQT port is also new on there. It's a vertical port And allows you to connect, you know, any of our dozens of stem IQT or you can use a Grove adapter to connect Grove I squirt C sensors or from spark fun. They're quick sensors or there's a lot of companies now making Sensors with this adapter cable, so it's plug-and-play. No solder required and you can turn off power separately to this port again with that GPIO pin there is a USB serial converter, which is now updated to a CP 2102 it can now do three megabits. There's also an extra tactile button on pin 38 And the USB has been updated from micro B to USB C so you can see like a lot of new stuff It's pretty much pin compatible with the original feather ESP 32 All the all the numbers are on the back the named pins like SDA SCL Mo see me so as clock a tx and rx those did change the underlying pin number because In order to get the ps ram, you know one pin disappeared and one once one pin disappears it can't turn into this You know every pin has to sort of change and so the numbered pins didn't change and the analog pins didn't change But the named I squared C SPI in New York pins did change So just in your code, you'll have to recompile it Which will need to anyway to take advantage of the extra flash and ps ram actually have to select the new board support package Just make sure you use the the words like mo see me so SDA SCL rx tx and that won't automatically translate into the numbers don't use the underlying like pin seven names for it But otherwise this should work drop in with pretty much any of your feather ESP 32 projects And it's just a big upgrade around the you know just everything got upgraded and updated It's so much better more pin labels on the top. So I'm really psyched to release this more mounting holes So good feather ESP 32 Okay, well So reminder top sensor That's to code 10% off in native fruit store Okay, we're gonna do is we're gonna do some top secret while we're doing top secret Load up your questions. I already got some lined up in the chat go to a to fruit dot it slash discord or discord dot gg slash it fruit and Join tens of thousands of us and we're gonna answer your questions. Just a sec, but let's do some top secret From the a to fruit vault, it's a secret But not really because we broadcast it live. Okay first up. We're gonna play a little video This is the ESP 32 v2. Yes It's top secret version of the video and then we're gonna show a couple of things This is a new product that's just about ready to come off the machine line. This is the ESP 32 Feather v2. It's a kind of a holy spin of our has a ESP 32 feather and what I'm doing is I'm checking it against the Fabrication print. This is the cam file And I've removed all like the copper traces just see the components and the names and the values so I can Verified that what this is is the same as what this is and like once in a while I catch in the steak or two because it's kind of confusing there's so many components in the pack so tight But this I think is ready to go We're gonna put this through the oven and then we're gonna test on our tester and if it's good We'll put it in the store Okay, and then you have a couple designs. Yeah, I was thinking of you know this picomodule on the feather ESP 32 v2 is kind of cute It's smaller than I thought and so I thought I'd maybe design and it's a bit see version. So it's the top and this is the bottom For it and then I've got the pinout diagram which using pretty pins It's very it makes it very easy for me to make sure that all the analog pins are really all analog and you know Well, you know the all the GPIO pins have the functionality that I might want so For prototype, okay, and stay tuned all week as we show some sneak peeks and more and then of course next week For our top secret segment lady, let's do some questions. Yes, we're gonna get on here. I'm doing it. Okay, so Let's do the question. I'm gonna do a couple first and then we'll get to these. I'm gonna jump around a little bit so if we're doing a product pick and We don't have a ton of socks. Sorry. It happens. There is a globe parts shortage But we're gonna try to always make sure whenever we do the product pick on Tuesdays that there's enough in stock But things are just moving really fast. Sorry about that Next up How far out is the ESP 32 itsy bitsy? Can you say it's a few months? I mean, I just put together schematic last weekend Okay, next up. Is there a way to use a time-flight sensor in a floating-point way? Sub-millimeter measurement. It does not guarantee sub-millimeter precision So it will not be useful to get any lower number What is a safe way to bend the 0.5 inch pins on a t0 or to 92 transistor to a point one inch to use with the breadboard without damaging the pins The safest way is you grab the part nearest to the body with one pair of needle nose pliers And then use the other pair to twist so you're you're keeping the pin You don't want to bend the pin against the body You want to bend the pin in the middle of it and that's the safest way And this is cheap way to send one amp to on a pie. Well, I think I don't think you have to pay for anything It's so cheap as far as your time. I don't know like, isn't there a Debian player? I think when I've got I mean I look I only ran on Windows at the time But I'm pretty sure that there's been either forks or or skinned versus of other MP3 players Have you seen any data on how many microcontrollers the average person has just curious with all the CMD or p2040 expressive? So five thousand so I would say I'll just refine the question. I'll help out a little bit So I'd say average person is very different than like, you know and electronic enthusiast. Yeah, so Yeah, so it does seem to be that because we talked to like some of our Partners who do a lot of research. It does seem like There is folks who are completely committed to one platform forever for everything like I'm a pick person That's it. And then there's a pretty large group of people that have lots of different ones, especially now One of the things that we see if you're an Adafruit customer and I'll actually tell you how many how many orders were up to like as of right now Just to give you an idea. Adafruit's been around, you know, 10-15 years, you know things have taken off Rapidly in the last few years, but we were up to 2,000,790,776 orders So there's a big chunk of our Customers who do repeat orders who have almost one of each like whatever new processor is because it seems like the business is the new Business, so they're really pushing what they want to do with electronics So it's it's growing, but I would say because Arduino was around for a long time And then we did circuit Python on the samd's there's a lot of samd's, but now because there's Asking what's the most popular. I just want to know is like what which ones people use the most I think a lot of people have Arduino's Espressive yeah, it's changing really fast, you know an RP 2040 I think I mean I think Raspberry Pi did publish how many RP 2040 chips and boards that they have sold so far I don't have it off hand to check check the Raspberry Pi blog. I think they did post about it. Yeah Okay next Okay, I designed an RP Raspberry Pi based system to display distance for my friend and you to use backlighting Sorry backing his boat into a slip. Is there a way to waterproof a time-of-flight sensor? I think the time-of-flight sensor can go behind a glass piece Definitely more so than a sonar although there are waterproof sonars Check the Dev notes the app notes for the time-of-flight sensor design I think you can go behind glass But it has to be a glass that lets the light through so I don't know off top my head what thickness or type of glass Would it be useful to apply pretty pins to break out and feather wing boards in addition to? MPU's um, I don't think so because usually I Breakout boards the the pin has only one usage, right? It's like it's in general. It's like this is the power pin This is the sda pin. This is the interrupt pin Whereas the issue with my controller boards is the my controller GPIO pins can be like each different thing So if you look at the pretty pins with the ESP 32, it's like it can be a timer It can be like, you know an analog input it can be a high speed SPI like there's so many capabilities and And you know with circums on the samd's those, you know, those are so mix-and-match That's when you really need a diagram to look at because it's it's hard to look at a list and be able to pick out Which ones have the capability you need because you're kind of like mapping in your head Okay, I need four PWMs. I need like three circums and I need like an analog input Which what's the combination of pins that I can use? Next up How is the Flipper-duper board The flipper I'm waiting to finish the feather wing first and the feather wing did get prototype PCBs So hopefully this product I hopefully this spin is correct And it'll be in this portion. Okay, and he is about the rev see of the QT pie esp 32 s2 Um, I hopefully that the the PCBs are in are correct and we'll be able to get to them the next few weeks a lot of stuff got delayed due to lunar new year and lockdowns and Transportation issues, so this couple stuff is delayed a few weeks. Yeah Let's see I think that is Everything for now No, here we go What do you suggest is your best learning source learning sources outside the guides on the site any name sources come to mind? Well, it actually there's someone in replying in the chat the question is what are you trying to learn? I think Mark in the chat is working on some learned to PCB type stuff, but it depends on what you're trying to learn I would say stop by Instructibles type thing that you're looking for see if things come up Haxter would be another one I'm just talking about a lot of learning to electronic world YouTube Besides Google YouTube is a very popular search because you get to see something that you want to possibly build So I would say start with all those things first But if you want more like structured learning or more like curated edited learning check out Magazine comm and look at the maker shed and figure out what maker books there are There's a bunch you can look at our blog as far as topics and we We're crazy. We linked it everybody and everything and competitors and things that we don't sell So our blog has a lot of resources of things that you might want to learn So anyways, okay, that's our show for tonight. Oh, no more questions. No, I think I got a long There's so much it's stuff you can learn. I mean like that educational resources out there are incredible. I mean, yeah This is it. This is like the best time. There's no no time like the present. I no matter what you learn There's people sharing information about it Yeah, even buying pick in places when we bought one there was no information now There's some information. Yeah, and Mark had a good follow-up comment Find the project you want to do and all of the learning resources kind of come after that It's not like the old days where it's like, okay I need to learn everything before I could do a project now You can actually probably find the project you want to do and then you're like, oh, I've never used Arduino So I'll kind of pick up some of that. Oh, like I knew a little bit of Python. I'll do the circuit Python thing if you go to either our learn system or instructibles or somewhere Let's say if you wanted to have light up LEDs on a costume That's definitely there if you wanted to have some type of robot that did something. That's there So, you know, the only thing that's hard to do now is probably decide what you want to do I know trying to find it's the focus. That's tough. All right. Well, it's a great show. We had The show. This is like the biggest show in the world. It's it's the it's the biggest live electronic show at 8 p.m. To 9 p.m on online, I think Yeah, alright, so that's our show Thank you everyone who's helped out in the chat tonight. Very much appreciated it Please consider picking up some top sensors a code you save a bunch of money and you get free stuff Special thanks to the car who's running things behind the scenes here at Adafruit in the slack channel Special thanks to all the discord moderators and all the helpful community You know, it's great is hanging out in the Adafruit community because it means it's possible It means there's a place where everyone can show and share stuff together It is a nice break from a lot of the chaos and not so great things in our lives So thanks everybody for doing this and hanging out together and keeping it going. It's been a long time For the last couple years, but this is the longest mark yet January was long But we're calling out of this and then like this one little update because I didn't do it in the beginning The show is starting next week at Adafruit We've been cautiously optimistic about the COVID numbers and we're doing Mass in common areas, but then all of our time teams vaccinated So at their desk locations and everything including Lady and I were distanced from folks We're going back to not having to wear a mask because everyone's vaccinated. So Things are looking good here. Just to give you a little bit of information on the ground here in New York City We've been going out and doing things and joining New York City again Seeing friends that I've been visiting So cautiously optimistic is the word Words That's the word the last two years. Yeah, okay. Okay. Bye everybody. See everybody next week. Thanks everybody Production here is your moment of zener. Bye ready
