 Live from New York. It's ask an engineer everybody and welcome to ask engineer. It's me Lady Aida the engineer with me Mr.. Lady Aida we're broadcasting from downtown Manhattan in the secret Aida food headquarters Where we do all that prototyping and development? We'll be back in the factory soon, but a schedule allows it with her every day But we're there, but we're doing the shows from our other location. That's right green screens. I don't know if you can tell Awesome showed tonight. It's good to show and tell super jazz about it There's a lot of cool people came by and showed some cool projects, but we're here for the next hour or so And we're gonna get off some engineering some art some electronics some fun. Make you think make sure Tell them what's on tonight's show show We're celebrating International Women's Day. It's women's day today 10% off in the Aida food store all the way up to 159 p.m. Eastern Time use it or lose it get anything that's in stock 10% off, you know, you want to do it You want to support a woman owned company? That's yeah all month long I'm also doing women's history month, but I think we're the only open source Electronics company that's woman on so spend a buck to it helps us pay our team and do all things that we want to do like these shows Talk about our live series of shows Ludic Chantel We just wrapped that up Desk of lady and we did that on Sundays including great search lady. Don't talk about what was on the show JP's product pick of the week will have a little bit of a recap from this week time travel Love cool news looking around in the world makers hackers and engineers from the mail bag real cool Special one this week help wanted we did some changes on how we're posting jobs more I went over that last week, but I'll talk about that again And we have a gigantic retro tech section because it is Marchintosh entire month of celebrating retro Mac stuff We'll show some of our collection and more that we've been posting around on the Internet's including our Newly dusted off tumblr. We'll talk about that some advanced manufacturing main New York City our factory footage some 3d printing some Ion MPI this week. It is Amanda. We'll do some top secret. We have some cool stuff There are some new products. We answer your questions. We can only do that on discord Well, we can do other places, but it's just easier for us so info.it slash discord stop by ask your questions We'll do them throughout the show, but ideally just hang on to them to the end We'll get to all of them all that and more on you guessed it Ask an engineer ask an engineer. We should do a song for that. Okay Lady Ada in addition to that cool code Wednesday people get free stuff when they add it to their part. What do they get? Well, and it's gonna change soon So this is kind of like the last day that we're gonna have these exact giveaways We still got $99 or more the half-sized perma-proto breadboard great for taking your subtlest projects and making them solder full 149 or more. We're still giving away the kb2040. It's an rp2040 based board with stem EQT and buttons Castlated pads usb-c and it's pro micro pinout compatible. So it's great for all sorts of microcontroller projects That one a little bit of boost in power boost for the 324 what else look to our 2040 199 or more you get free UPS ground shipping in the content of the United States And this might be the last week for last week that we have a freaker base Tell you why I'll tell you why though if we're getting back to circuit playground expresses Which we'll talk about later next week when you buy stuff You'll get one of these bam this week when this stuff you get one of these Why because we didn't have time to swap them out Well, we've been waiting for Microchip samd processes for like two years. So they came in that just means we're retiring out this freebie. So Use the code use or lose it Get the stuff freebies Celebrate by saving buck to okay. We do a bunch of live shows do them every week The live show that we just did good to be back. We had the team do The co-hosting and hosting. Thank you Chantel is kind of One of my favorite half hours of the week because we get to connect with the makers in the community Uh, j stop by we had folks on our team with stop by Um, and then if you watch the whole thing all the way through. I'm not specific favorite product, but uh Project but um, don't you stop by and made The floppy disk The display on it and then talked about some future projects. They were all really good projects It's actually neat to see people build this because it's like wow the instructions and code work Like it's one thing to build one. It's very hard for other people to build it. I think that there's probably um similarities when you're someone who Makes something for others to make like the delight someone gets when they make your recipe And they taste it like it was tasty and they not only taste it and they like the recipe but they Um shared it with important people in their life And I think that's neat when you can make something, um, you know all of our team They take the things in their head And some of it's 3d printed some of its code and all comes together and the floppy disk thing is neat I was talking about a gift that I want to give someone it's uh the contents of what's on the floppy Yeah, is oh, yeah on the screen. Yes, cool. So I thought that would be kind of cool So anyways tune in every week 7 30 p.m. Eastern time come by if you have any mac retro stuff Come by and show it off because we're going to be doing March and tosh All month long. So, you know, um, we do Jessica bladey at every single week. We did that on sundays. This is where we live bar cat from your desk Yes, which is like right over there. Uh, what'd you show off this week this week? Um, show off some more bones boards So every week I tried to design like one or two We should first off talk about march and tosh or she'll talk about more That was a quick thing with the penguin. Um, I also showed off we have a usb host rp 2040 feather That uses the bit bang teeny usb usb host capabilities that we've added recently Does work also showed off this cool. Um, did you keep part of the rgb led in the usb a port? Yeah, uh, also some canvas stuff we've been working on we got that working so it'll be in the shop soon Uh, and also made an rp 2040 can bus feather. So lots more. Yeah, and then we also do a segment called Where in the world is that part I need? It's a great search did you keep and this is when you use your power of engineering? to find things on Did you key dot com using their search? Which is an art form in itself to find the things that you want. So what did you look for this week? Um, so this week I am experimenting with the esp32 s3's ability to drive dot clock TTL displays And uh, so folks may not know did you key stocks all sorts of different dot clock TTL displays? for immediate shipment IPS capacitive touch resistive touch 4.3 5 7 sizes. Whoo. It's a party. Um, so check out the um The video where I show uh, some of the companies and some of the things I searched for and you can uh, connect those top dot clock TTL displays To uh, some bigger chips like the imx series and esp32 s3 Okay, and then um, every single Tuesday we do jp's product pick of the week This is a live broadcast inside a product page that discounts automatically pride. Um It's a fun show every Tuesday. Here's this week's highlight It is the 1.8 inch tft display breakout with micro sd and iSpy Having that little flip connector there so that you can put a Ribbon cable in means your your wiring is so much neater. You can see I've got one of our 1.8 inch tft displays with the iSpy Connected up to iSpy breakout and then that's running to an itsy bitsy m4 This is a this is a really cute Game that's on the main page of makecode arcade that is about uh, some mice performing shakespeare And you are the spot operator and you got to keep the spotlight on the actor who is currently delivering lines Which is adorable and amazing and I love it. That's my product pick. It is the 1.8 inch tft display breakout with micro sd and iSpy All right jp's workshop is on thursdays and then deep dive in scott. I'd be Coming back to the chair. Wow. So we'll see how that goes Fomy guy is out this week. So we might see scott. I'll be the tuning if I can. Um time travel It's ground in the world of hackers makers artists engineers all the stuff that's going on In the world and more this week's time travel. Let's do some Celebratory things first on adafruit site. There is women's history month all month long There is all sorts of posts videos articles and more on our site, but There's also that's the tag if you look around online You're on the social medias you can see the stories of many amazing women and the things they built and shared in fact Um, I sent a note to our team to publish this up because i'm doing the show Sparkford has a post about headie lamar and we had interviewed the director of a movie about headie lamar So I said hey post a link to their site because they're an electronic site that's talked about women attack. Yay We want this to be contagious and these stories get out and then we met the director of the movie tragic story The amazing story all at the same time Of headie lamar. So check that out. Um, that'll be on our website and it's also Um on my thumb Happy birthday raspberry pi Yeah, happy 11 years They've been at this so they launched raspberry pi in 2012 Goal of boosting young people's engagement with computer science and electrical engineering and in the decade since there's been an explosion of interest and more You can tune in Um to this special online event. I believe they're broadcasting online. That is but check it out It is coming up march 28 2023 6 to 7 p.m Um, I think they're recording it but double check, but if you're in the area Um, of course, you want to see this. So happy anniversary raspberry pi. Here's to another 11 years. Um Next up I wanted to mention that uh, so twitter kind of melted down a long time ago. It's just now getting equally distributed Um, so we're on tumblr. Um, we've been making sure that We're putting our content in places and we're the humans behind it. We don't auto publish in those places So we wanted to make sure folks who like doing retro stuff like doing keyboards Um, tumblr has a live video feature. Um, we were playing around with that Um, there's a lot of people who will find cool old um, like magazine scans From the computing history and then put it on tumblr. They have theme tumblers. There's a lot of cool tumblers So we've been on tumblr since, um It's been 13 years and I looked on archive.org when the first time it it pinged it So here we are. This is our aida fruit industries tumblr This is one we used to have our blog feed go there. So february 11th 2010 and you can see what were we doing 13 years ago from nata fruit shop messing with an i-fi card Yeah, we were we were taking photos and it would transfer the photo over wi-fi from the sd card and then automatically upload Yeah, this is kind of cool. I mean at the time this was amazing because there was no i-fi We're uh, I don't think so There was An i-fi there was but I don't know if it did photos to blog automatic blogging it Everything kind of did but none of it was easy. Yeah, I think it was called like there was one service I used it was like the first auto mobile blog. It was like called text america or something like that. Anyways, we used to use Ustream um in our stream So anyways, um if if you want go check out a to fruit tumblr.com or tumblr.com Slash a different the reason that we have our content in all these places is because this is where people build communities and a lot of us are on these places anyways, so on Some social networks like instagram. We try to put our beautiful photos there But you know, you can't put links in the text So it doesn't really make sense to do a large form bits of text but if you're like looking at like our amazing photos and and um, some of our Cool photosets of richer stuff. That's the best place where it went like the human beings posted there We don't automatically post stuff there either via bots So um, we're going to be experimenting more if you're on tumblr Go check us out there hit a little like or a reblog and uh, we'll probably see how it goes We'll talk about our Mark and tosh stuff that we're doing there and then next week we're talking to the tumblr folks and you know tumblers change a lot We uh, we had met. I don't know if you remember this, but we met david karp a million years ago Yeah, he came by and he came to eat a fruit. Yeah, and we also were it was like a white part bitch Yeah, it was it was apartment air for and he had started tumblr and then we also went to um a laughing squid event and I think tumblr had like 10 people at the time um users not employees And then um They got bought by like yahoo and verizon and we care, you know got really weird So we're just like, oh, let's just retire out the tumblr and then we'll See what happens. So I just wanted to make sure no one squatted on the info name. So anyways, it's back But um the the new crew it's owned by automatic which is wordpress And they you know, I kind of like these the they have a mission statement They they talk about the privacy of the users tumblers dedicated to realizing the most radical kind of principles And also individual Freedom and expression and human connection. I mean all this stuff sounds good. We're trying to find a place. That's not the worst thing ever We don't like using facebook don't like using twitter It's just you know a toxic dump of people hating each other and dunking on each other. So we're gonna try it We'll see how it goes. We're also on mastodon Check us out there. It's of course so good, but it might just be because all the bad people on twitter didn't get there and ruining it um we have everything on Our tumbler that we're doing in the retro world right now It's neat because you can put photos and videos and long form texts And people can I mean the tumbler tumbling is exactly the kind of lung you do. It's like photo tax photo tax And I expose all of our likes This is what lady and I click like on and all of our following and followers because um, we're proud of it I thought this was cool. This is a science fiction book. We're gonna get this for our kid This is women of wonder science fiction stories by women about women. Look at this cool like robot kids. That's sweet. Yeah So if you look this is just like everything I like is just here Like weirdo batman And this is cool stuff. Anyways, and then you can look at all the ones that we're following So hopefully folks will we'll get a kick out of it. Hey, oh, and then the other thing is here's our um Here's our mastodon. Yeah, and we're putting all this stuff go boost our toots. Yeah go boost our toots Toots are boosts Um post our boots. Yeah. All right, feel like Okay, so this week we have a very special mail bag The io team has been working so hard and making things so easy for people to do things And you know, I tell the story that once in a while we get an email that someone says you're making things too easy But I thought this was a really good Uh discord message that we got I would like to just say how incredibly impressed I am with the io aideford io has become I built a simple weather station back when aideford io first came out It was one of my favorite projects, but I'm just a hobbyist and I haven't touched projects since years later I finally have more free time and I just ordered a couple new esps and I was absolutely blown away How unbelievably simplified the io process has become with whippersnapper That must have been a ton of work for the team. It was and you should all be very proud I will quickly go back into circuit python, but whippersnapper will allow me to help spread my projects to friends that were previously interested But just too afraid to follow. Thank you so much for all your hard work. You spread more joy than you know Okay, that's high praise and we were talking about this in our in our Chat room for the team. It's like how often do you feel good about using a website or feel like oh my gosh like This This is joyful like how like how often do you think about that? There's a few websites I can like say like oh that was like that was fun, but most of the time it's like terrible When I feel like you see like ads and pop-ups and subscribe I feel like something is like, you know, I feel gross. I have to take a shower for some of the size that we have to use so um Thank you for letting the team know about this because we have been making things we thought how Things could be which is easy and then we want to make them even easier Okay, next up jobs board We don't have a jobs board song Maybe it could be A song like Dire straits like money from nothing So we made some big changes in our look I have to cover one song We made some changes. So we were running a wordpress instance for our jobs board It just got crazy to Manage all the time security issues come up with all these things managing it and then in the end I was just helping people post their jobs anyways. So um, we just consolidated it to adafruit.com slash jobs It's also adafruit.com slash careers and has our jobs on there And what we're going to do is start with it being Very simple easy for us to maintain to have your skills that you post up or Jobs that you have that you want people to apply for but we're going to be integrating things with our learning system Which is a great authoring tool with everything just works and we don't have to worry about Running another server just for a jobs board. So that's a minor change that we made Thanks for your patience. Um, a lot of people have gotten great jobs through our jobs board So we will always do something but I just wanted to let you know It was just like getting complicated and maintaining yet another Instance for something where I can just do like get up pages. I could do something as a static page Um, you know, we don't like customer data or or personal data So we want to make it so it protects privacy. We also will always moderate and improve jobs as well. So they're not scammy Okay, retro. This is the big one cool I know I see all these images and videos and I'm Yeah, I'm getting excited. Yeah, we get a little bit of a break here because there's a lot. Um, so we're doing our retro tech um, I guess segment all month Or series all month. Um, it's marchentosh. You can go to marchentosh.com and learn about this Check out the cool art that they made Um, and marchentosh is a month-long celebration of everything right before kind of the most recent max and stuff like no iPhones No os 10 no s 10 only nine or earlier. Yeah, and um, if you look at, uh Go to our website you can find it you can also just you know Our tumblr is kind of where we're focusing a lot of this stuff. Um This month because a lot of people are also participating. Um, you can you can check it out there It's all there and it we post something every day. We also put in our discord channel That's called marchentosh and we tag it and um, what we're showing off is our collection that we have Um collections from other people cool hacks and mods that you can do projects from eight or fruit. Um, You want to run system seven on like a weirdo little single board computer? We'll show you all right, so, um, I'm gonna show some commercials from the past I'm gonna show our quick time 150 Um, I took a photo of you. It's a 27 year old digital camera still takes good photos or you're just a good subject one of the two um an apple power cd Um, a very weird apple console that there's only a few out there There was like basically a prototype, but they wanted to do console boxes before apple tv the pippin Which is an apple gaming console and more so, um, i'm just gonna play these there are some very cool gaps of silence And then there's some weird, um commercials and ads and stuff like that So enjoy the silence and then i'll see you on the other side for the rest of it So go in time. It's your moment of marchentosh Welcome this guided tour shows you some of the many ways to use your apple power cd The power cd is three products in one a photo cd player for your television A portable cd rom drive for your personal computer and an audio cd player The same photo cds that you view on tv can also be used on a computer You can use photo cd images for desktop publishing business documents and multimedia presentations Over here in the united states. We have itv at the next station quick draw 3d quick draw gx, uh Pippin It's python on hardware time Okay, every single week we talk about all the things on hardware that happens to run Python we have a newsletter. It's aether fruit daily and go to aetherfruitdaily.com Completely separate from your store account because we don't like to mix the two Because your personal information is yours. You don't spam or do anything like that. So We're gonna show a video which is a little bit of a preview on the m7, but we also have a bit of news the circuit python 810 Beta has been released lady aida. What is the latest and greatest that people should consider test and more? That'll help them out in us. We still have um handmade gift support It's still kind of in progress of being tested But it's still kind of neat if you want to try Loading small gifts from disc and displaying them on a tft display Should work on oleds or color tfts we've got support for 7 inch Ink displays and we do like auto dithering within of them and that's part of also the palette stuff a lot of It's mostly actually been a lot of bug fixes to be honest for a major release That's usually yeah, we have a huge churn of bugs Keep finding them posting them the circuit python github repo and we will Check them out. Also, you know, we get usually a lot more New users with a new major release and so that will also kind of get some exciting new bug reports coming in and then um in circuit python news the m7 We're working hard at it to get circuit python and stuff going. So we have a video I was gonna stop secret, but I think it's fine. I think it's fine This is kind of nice good python news because we have a very cool new board set together with jeff Hi jeppler here with another quick video This is the beta version of the Adafruit metro m7 board in that Arduino compatible form factor that many of us love so much And the final version of the board is in the store now There's a lot of stuff for us to add to circuit python before that is Moved out of alpha release quality And so to get my fingers To get my toes wet excuse me I picked rotary i o which means I need to know about how gpio pins work and pinmuxing and pin interrupts And just to show that the proof of the pudding is in the eating as I rotate this knob the onboard neopixel Will cycle through the spectrum of colors So that's what i've been working on and you should keep your eye out for more improvements to our support for the IMXRT family of micro controllers in circuit python 8.1 and later on circuit python 9 Get it delivered every single week to your inbox adafruit daily Talk to us recently. Okay. Uh, we're an open source hardware company We have thousands of guides over 2,600 guides all together this week on the big board lady What is new for folks to want to check? Hey, we've got all sorts of Okay, i'm trying to remember because there's been a lot of updates safe mode. We talked about last week I think the snes mouse is new. Yeah, a lot of these are just updates So this is a project that jebler did To take the snes mouse, which I didn't even know existed But like how can you not love it that like beautiful purple tinted button? and it uses I think latches just like like sns controller, but it's a mouse and then connecting it to a RP 2040 cutie pie to turn it into a usb hid device So it's a it's a cool project if you want to use this retro mouse Um, I think the cutie pie guide got some good updates We do have a new guide for the esp32 s3 reverse tft So, um, it's got the pinouts diagram and some example code We just did a whole family of these esp32 sx feathers with like display with that display reverse display not I will say that the you know if you're watching this live and the esp32 s3 is having a little bit of a Jitter in the arduino ide. There's a couple issues with uploading and and esp tool And so if you're having a couple issues just just be aware the s3 in particular is going a little bit to a churn The s2 doesn't have these issues, but i'm noticing more um You know bug fixes and hardware fixes for the s3 So, um, hopefully that'll be fixed by the idf team Um, the analog feedback servos guide got an update from carter now has circuit python code and a gif So you can use analog feedback servos and circuit python Um, erin made a really cool bubble table with led animations. Um, this is a great, uh project if you're interested in Having led animations that are controlled by an ir remote Irremotes are inexpensive and you don't have to worry about bluetooth or wi-fi or pairing you point you click a button Things change and getting to work with animations isn't hard. Um, but you can do it You want to do it so that like the animation changes immediately and it takes a little bit of, uh, funky coding So erin's shared that code. So this will be very useful for people in general who want to do infrared remote controlled led stuff We're going to play the video after this and then we also have a video for the trondisk, but the trondisk is Get another Yes, amazing trondisk. This is cool. I guess there's a there's a tron ride, which looks awesome And I guess it's an ebcon center. I don't actually know. Um, or disney disney something disney world land I don't know. Um, but if you're gonna go there you want to cosplay You know, you gotta go like this. You gotta go like this. So the cool thing with this disc is We're just in the grocery store. It's really printed Um, and it uses the prop maker feather wing and the nr 52 840 feather and it's Magnetically attached so check that out. Yeah, so I guess they they picked up a a tron hoodie And then the harness has magnets attached on the inside Uh, so you can have it magnetically attached to your back. So like I thought that's the cool part Yeah, very cool. Bye for the user. And then Liz wrote up a guide for the Adafruit pi cowbell Adalonger, which gives you a micro sd card a real-time clock stem iqt and reset button So we're starting to add more Pi cowbell accessories that let you um add functionality to the raspberry pi pico and pico w and this is the second one So you've got example code in arduino and circuit python. All right bubble table taken away There's some factory footage. Hey, look there was a that's that's such a nice note. We had to So nice we had to look at it twice. Yeah, anyways, that was major city factory footage. I was looking at that thing yet That was such a nice Okay, let's do some 3d printing See this show is so big that I have this grid of all the things that we put together for the show and It's like it's like a five by five. It's like a tiny it's it's smaller than the x's on close this ad It is it is like threading a needle costly. Okay. Um, so we're gonna do The tron video and then the speed up and then we'll see you on the other side for ion and pi Lots of videos this week. All right. See you soon You can fight for the user and build this 3d printed tron inspired prop using new pixel leds and circuit python Powered by the adafu feather and prop maker feather wing this tron disc and back harness are fully 3d printed With the power of neodymium magnets this disc attaches to your back just like in the movies Using a mobile device and the blue fruit app You can change the color of the leds so it's easy to switch your team color With the blue fruit app for ios devices You can even use an apple watch to change colors with the built-in color swatches The prop maker feather wing and feather blue fruit are the perfect pair for making advanced props with motion activated lights and sounds That can be controlled wirelessly from your phone The code is written in adafruit circuit python So it's easy to make it fit just about any prop with lights and sounds It uses bluetooth and the led animation library to trigger lighting effects with the prop makers on board accelerometer Check out the learn guide for full step by step tutorial on building this project and download all the files using the project bundle downloader You can customize values like the speed and colors to make this fit your project Circuit python supports lots of different dev boards Just go to the website and search to find your favorite microcontroller You can download the latest stable version using the download you have to button and quickly get up and running Get the parts to build your own tron inspired disc from the adafruit shop links are in the description Download and 3d print the parts without any supports using black and translucent colored pl a filament Start by soldering matching headers to the dev boards You can use a breadboard to help you solder them straight use short socket header pins to keep it slim and low profile Perfect for props with tight spaces The feather blue fruit is secured to the bottom piece of the prop using hardware screws A mini skinny strip of medium density neopixels are set on the outer edge of the disc Cut the strip to size and remove the silicone sheathing by sliding it out A strip of side lit neopixels is soldered in line with the mini skinny strip and shares data power and ground connections A three pin jst connector allows you to plug into the prop maker feather wing This micro usb breakout board allows you to route the usb connection to the edge of the prop So it's easy to access for recharging the battery use silicone ribbon wire to create a super compact usb cable A mini oval speaker plugs directly into the audio port on board the prop maker feather wing and snaps into the built-in holder This slide switch is soldered to the enable and ground pins on the prop maker so the feather can be turned on and off A jst extension cable connects the battery to the port on the feather and the battery clips into the built-in holder New dinium magnets fit into the built-in cavities and get secured with 3d printed caps that snap fit and hold them in place The led strips are tacked down using double-sided foam tape The top cover of the prop can then be placed over the bottom cover Nylon screws are inserted through the holes on the side of the disc and keep everything secured An accompanying back cover with magnets are sewn into a running vest using nylon thread or fishing line We had a lot of fun building this project and had a great time taking it to the tron light cycle run at the magic kingdom in disney world We hope this inspires you to check out aether food's prop maker and circuit python for your next project Jump right in but first Don't forget there's code and you get free stuff when you Order you want to get free stuff and use the code You ready lady? Yeah, take it this week's island of p.i. is from Amanda lady, and what did you find this week? Okay? So this week it's a tool that I was like I want this and once in a while you'll see like I do like very complicated boards like last week's nxp series, which is sort of like this massive So you're complicated That's like that's a complicated board Yeah, they want to cover this entire family. This one is a short and sweet one But I I'm very excited about this one because I personally wanted this tool. So this is the wick gun by Menda easy braid easy braid is like the sub brand for braid and then Mendez who made like the thing it clicks into and this This is like this this will get rid of your solder bridges as easily as john wick gets rid of Nasty bad guys. So, um, yeah coming to a theater near you. It's got a hundred percent Let's go for motions or getting out of hand. Yeah, okay. Look. I had a few minutes. I got my john wick happy meal I opened up photoshop Okay, so the wick gun is um It's a tool that you would use with solder wick. So um any dunny who has soldered knows that soldering is super fun and easy until you make a slight mistake And then you got to get your tools out like here from phil b's guide on Removing the headers. I'm sorry the headers and connectors from rosemary pie Upper left you've got a desoldering tool also known as a solder sucker Top right is the flux use that to kind of Keep the area clean and it keeps the solder from sort of spraying everywhere. It makes it flow a little better And keeps it away from sticking to the pcb where it shouldn't and then at the bottom right there super wick so wick is A braid it's made out of copper And it often has that flux inside of it or a rosin side of it That makes it easy to clean solder joints And then also the rosin kind of coats the solder joint and keeps it clean Um and unoxidized later So um usually what you start with is a solder sucker, you know, especially with through whole parts solder suckers are good when you have a A lot of solder you heat it up you put the solder sucker up against it And um you press the button and a little spring pulls back and the solder goes up And then you'll usually need to clean up afterwards with solder wick like once in a while you can get away with just the solder desoldering Pump or the solder sucker But with smt, especially or when you have If you go back to uh, so I feel like this example for the raspberry pie When you have like those big connectors you see the usb connectors were removed um and solder suckers work really well when they are pressed up against like a solid blob But if you're trying to clear out a hole or something already has a hole in it air will flow around the solder So it needs to have like something to suction against and then that's where wick would come in But wick isn't good for huge blobs like it really quickly saturates. So it's good for like the little cleanups So once you go ahead to um, so here's showing, uh, you know after you can see Like the, um Larger holes still have a little bit of solder in them. They're chunky solder You're not going to lose a solder sucker to get this out. That's where wick comes in and just does the the fine work Um, there are a bunch of really good videos on the ggk youtube that you can Watch if you'd like to learn about soldering and desoldering including this one by becky stern only a couple months ago uh and then uh Also a teaching moment, um, has a really good guide on using flux and wick to desolder and clean up solder joints um, and there's also um I didn't put it here, but uh, uh, shon hema also has a guide on Soldering smt qfn connectors doesn't cover wick, but you could be handy. All right. So the uh, 1000 wick gun How do you use it? So you get these cassettes? Um, and you pull out a little bit of wake. I'll show you a little video later You pull it through and there's um, a little roller at the top that you pull and as you pull it It um feeds the solder wick through and then there's a little like Nail clipper end and when you pull the trigger it cuts the wick out And so basically you can always make sure you have clean wick, you know, actually maybe let's um, I'll show it on the overhead because it's a little Confusing if we can jump to the overhead real fast and then I will Do you have anything or no no no I got it Okay, so um, this is it and then You can see as I move the uh trigger it. Sorry the the roller The wick is coming out and then when I'm done and this is the wick and then I would you know use it And you know solder solder and then when I'm done You clip and uh, you clean it off and then you can get um fresh wick. Obviously, I'm not going to solder live, but um You know, that's the idea behind uh the wick gun and then this cassette Um comes out. It has 15 meters of braid and of course you can get a new braid very easily. Okay, so let's go back to Um So, uh this tutorial shows you how to use it. Um You can take an apart clean if you have to uh and then Yeah, you can also pull back like the drive now works both ways by the way So if you like pull if you feed too much out you can always feed back. Okay next One Okay, so for options. Um So it does come with these cassettes, you know So like once you when you can buy it with the cassette and then once you run out you get new cassettes um, it comes in different widths Uh number one through number five and I think the one that I was just showing you is I think a number Let's see that was a number one and then Let's see. I also have a number four and I think the Larger the number the wider it is. It's probably as basically the cartridge or is it that's it You can reload the cartridge if you wanted to but it's kind of a pain and it's about the same price to just get like new solders Like oh, yeah, so like this is the number four So do you want to go with the overhead again? Yeah, just quickly. I'll show the number four So this is the number four and that's the number one. So it's approximate number millimeters wide ish about you know That's how wide it is and then you know the wider stuff is better with Larger through holes the cassette chart and then this is a cassette chart. So you can you know, the cassettes themselves you can pick up um, the wit gun itself is like, you know, 20 bucks and the cassettes are about 10 bucks a piece Uh, 13 bucks a piece and um, yes, you can load them by hand if you if you want There's no reason why not to they they pop open and inside is just a reel But most wake comes in like these kind of plastic pop open containers or really large reels So you'll be sitting there and you'd be winding it. So it's it's up to you Um mend and easy braids also have a bunch of other tools. They have these nice bottles for isopropyl. They have little spudgers. They have Uh diagonal cutters, etc. Appliers. So check them out. There's a whole series Available on digki, but the thing that's really great about this I'll tell you why this is so great is when if you're using Soda braid, you know that it's usually okay. Here's what you do your soldering and they're like, oh No, I need you some braid. So you put down a soldering iron. You pick up the braid You have to pull out some and you're like kind of messing with the reel and then You hold it in one hand and you position it and you pick up the soldering iron again And then you do so right then you put it down and it's like there's a lot of like it's like fork knife Switch hands move up and down with this. It's one-handed. So, you know as you're soldering if you're like you you put down your um solder and you're still holding the iron You can pull this out and then extend some wick out clean up and then change You know you don't have to put down the soldering iron and you just the go back and forth between solder and braid Which is what I really like it's available to digi and it's in snaggy digi. Um Baby, well, no, no because they have all the different families. This is just the one Okay, quick quick quick quick quick quick bite. Yeah, but they have like there's like 30 different types And there's like five to ten of each one. I'm so used to chip shorties. You're like, oh, there's four No, it's fine. Yeah, you'll find some because I picked like the number one, which is the narrowest But you probably want like number two or number three Um, they do have them all in stock Of course I picked up, you know one of the four and one of the one because I personally want this because I'm tired of Putting down the iron and stuff and we got a little short video and a video and it's in like a tiktok format So, uh, we'll play that check it out. Well of course Since tiktok came along youtube has their identical Yeah, and then so does everyone else. It's funny. It's like one format takes off and I was like I was scrolling through I had to look up some stuff and I'm just like, wow youtube is now Filled with shorts. Yeah, because that's what they're calling them. Yeah, any who enjoy the format Yeah, I guess so excited about it. We always have to prove this is a live show I saw new and I was like if time seemed to be a great set of freaking price Okay, ready here we are. Well, let's do the code but then but now really really really let's kick it sing it new new new new new new new new new new new new new new new new new new new new For real. We played spoon man on repeat today. Come on Okay, uh First up, um, we got some restock Back in stock. Some of the chip shortage is finally over We've got samd21 e18's in and so we've got the cutie pie samd21 we've been Going over with the rp20 for a while And of course we've got the ESP32 version and S2 and S3, but some people want the classic. So we've got the classic. We also have circuit playground expresses back in stock. Finally, finally, finally, there are tons of schools and tons of things that have been come up, that happened to all of us for the last few years, but it's happening. It's here in back. Yes, it's back. So if you've been looking for circuit playground expresses and we'll have some of those base kits on stuff, we wanted to get the original back in. Now we're gonna get all the sub kits in stock soon too. Bye. Okay, next up, we've got re-legendable keycaps in black. So we had them in white, but some people were like, no, I want them to be Gothar. So these are two-part keycaps. And you can see here like the plastic piece. So you can remove the top from the bottom and then you put in a sticker, a little piece of paper, a label, they are MX compatible. They are fully symmetric all four ways. There's no tilt or anything. And they're basically like DSA profile. Not exactly DSA, but they're basically DSA, but fully symmetric. These are really good for if you're using a MacroPad. We're selling in packs of 10 because no matter what number we sell in a pack, it's always the wrong number. So we just pick 10. Like the hot dog bun problem. Okay. Right now, so it's 10. Next up. Next up, we've got an update for the Winni Pi 4 Mini. A couple updates. It's USB-C. They've kind of redesigned some of the components. It's functionally the same. This is a nice little real-time clock and like automatic shutter up or shutter down are like one button to shut down and restart. It's got built-in battery backup. It's a very nice, nicely designed real-time clocks slash power management tool for your Raspberry Pi. Even though it's Pi Mini-sized, like Pi Zero-sized, it'll work with the standard of all-size Raspberry Pi as well. It looks like a very nice build. All right. Next up, the star of the show, besides you, besides our community, besides our customers, besides our staff, this is finally here. There are so many things we've been waiting for so long. It's here. It's in the store right now this second. Yes. I did put someone in store and I didn't notify people so that everyone... If you're watching this show, you can actually get these right now because if we notify everyone who signed up, they'll instantly go out. But if you're watching a live show, this is why it's special to watch those shows. It's here. It's really here. I'm a guy. All right. The Metrogram 7 is our first board for the IMX RT series. This is a very powerful series of chips. We've had Cortex-M0s. We've had some Cortex-M3s. We've had Cortex-M4s. Why not more M's? Cortex-M7. So this is a powerful core. You know, it's got floating point. It's got a very high speed clock. Oh, we got beautiful photos. Cool. But you know what? Let's see. Do you want to show it live? Do it live. Do it live. So this is the Metro-M7. I'll put it over here. This is great. We can see us. So in the middle is the Metro-M7 chip. That's this one. It's the IMX RT-1011D. So it runs at about 500 megahertz. It's very fast. The trade-off is that this chip is fairly inexpensive for how powerful it is, because it doesn't have a lot of RAM. And I did want to mention that. So it only has 128K of RAM, which sounds like a lot, but like you need to have like half of it for the, you know, instruction cache, which we might tweak in Circuit Python. But basically it feels like 64K of RAM. It's not a ton of RAM. You can do stuff with it. It's very, very fast. But just be aware that you don't get to use all of that. And it's not a roomy, you know, like our ESP32s with PS RAM. They're so roomy and they have like two megabytes of PS RAM. Not yet. We're getting there. We're going to start with this chip that has 128 and we'll move up the family. Check out last week's IR9PI video where we talk about the family of our T-chips. We might move to the 1020, 1040 as we make our way up to the 1060 or 1160. So, you know, 500 megahertz, no built-in flash, 128K of RAM. This is the flash chip. It's eight megabytes. It's Q-SPY. So it's nice and fast. The second, the RP2040, the flash memory is off chip. There's boot select switches. There is a built-in ROM boot loader. We load it with teeny UF2 as well. So there's a secondary boot loader with that nice drag and drop and like neopixel lights up and all that good stuff. A lot of passives because it has the cool ability to generate all the internal voltages it needs from 3.3 volts, which is what makes it inexpensive and you can do it on two layer board. We've got the standard Arduino form factor which we just like to start with. It's familiar. We can use shields with it. A lot of accessories work with Arduino. So you can plug it in. It's a three-volt logic chip. It's not five-volt compatible. That's to be expected. The Armour Cortex series pretty much is always 3.3. It's sometimes five, but very, very rarely. You've got hardware SPI and I squared C. That means we do have a lot of pins, right? We have six analog pins. We've got the 14 digital pins here plus two I squared C plus another four SPI. So like do the math, it's like 20 something GPIO. And also SWD with the SWO pin connected. So you can do traces. Scott might do a video soon where he shows some of the trace capability of the M7 series. The SWD and SWO pins are brought up for advanced debugging. That's another reason I love the Metro format for chips. It's like we wanna get the debugger going. Stem IQT port, plug and play I squared C. There is also, you know, I had a bunch of space. So I decided let's stick a ESP32 on there. It has the airlift firmware. So you can use this to do Wi-Fi communication. So it communicates over SPI and circuit Python. You can use it to request website. It has the worst power for it to make sense. So it's like just to fast. It's gonna be fast. Well, let's do, it's gonna do computational stuff. And then we're gonna use chips that bump up the ramp. So we're gonna, it's gonna get juicy real fast. USB-C for powering, Neopixel, pin 13, red LED reset button, DC jack on and off, DC in, you know, nine volts, nine volts, 12 volts is good. Power supply regulator here. I might change this. I went with an LDL, but I might change up this five volt to be a switch converter on the next revision. We'll see. On the back, a lovely silkscreen come through bumpers. Some explanation of what you get in the board. But basically, you know, this is a really good competitor to the M4 series. So, you know, if you're interested in the SAMD 51, but you want more M-Hertz's, you want more M-Hertz's, you need to go from M4 to M7 and that'll get you 500 megahertz. So we're gonna, you know, we have some circuit Python support. There isn't Arduino support at this time. Well, something we'll look into, but it's not a priority for us. We're gonna kind of focus on making sure circuit Python works really well on it. But you can also use NXPSpresso, which I've used and they have, you know, command-lined make files that we've used to write code and it works really well. They have a good SDK. So if you really want to write like very fast code that runs in the processor kind of like natively without circuit Python, I would recommend NXPSpresso for now. All right. And with that, that is new products. Ooh, don't forget the code. It's Wednesday. Keep putting your questions in the Discord chat. We have some lined up. We're gonna do some top secret right away. Let's get to your question. Okay, for top secret, we're gonna play two videos and then we're gonna show off some of your latest designs. See you on the other side of the videos. Hi, Jepler here. You've caught me playing with my latest project for Adafruit called the Infinite Text Adventure with Circuit Python and OpenAI. With this project, which is running on a PyPortal with a lovely case by the Ruiz brothers. At every step, you get presented with four choices and you touch the screen in one of the quadrants to decide what you do. And I think before we go any further, we need a flashlight. The guide, I'm in the process of writing. The code is already up on our GitHub. So if you're enterprising, you can check it out now. But otherwise, look for this project soon and create your own adventure using Circuit Python and OpenAI. All right, I think we need to check the pile of papers. Can't wait to see what happens next. Hey, Lady, what's this? Hey, I'm going to do a live demo where we program this ESP32-S2 over USB from BitBang USB host on a Pico. This is very exciting. So let's plug it in, replace the tester. I gotta be careful to get where the plug goes. Make sure the board is on and press the button. So this is kind of neat because I'm using USB host to connect the ESP tool to the built-in ROM bootloader. I'm programming it with a GZIPT test firmware. So it's actually stored in the flash memory, not on a USB, yeah, it doesn't use microSD. It takes only 12 seconds to fully program and test this Metro ESP32-S2. And I don't need to use a Raspberry Pi. I love Raspberry Pies, but this is really fast and solid state. So I don't have to worry about any SD cards. So this revision is coming to the store real soon with this new faster test. All right, and then here's the weather report. Okay, so more Pico bells. So since I was doing a lot of CAN bus stuff, I thought it would be fun to maybe whip up a CAN bus Pico bell. So it goes on a Raspberry Pi Pico or Pico W and adds CAN bus using the MCP 2515 and a TGA 1051 transceiver and a little Bible booster. You know, I think there's no native CAN peripheral on the RP2040. I know that's just people who kind of like bit bang can, but I think, you know, the MCP 2515 isn't too expensive. I don't mind, you know, going with a chip. So you have like a well-known chip and as buffers and is note, you know, it'll handle and make interrupts for you and you aren't bit banging it because I think it's a good solution. So we're going to fab that. We also made an all-in-one since I was already there and like doing the stuff, made a feather RP2040 with a CAN bus chip also on it. So it's all in one. If you want to use a feather for battery powered tech projects and also the USB host feather, which I think is kind of the most interesting because it uses our bit bang USB host implementation in teeny USB things to keep them for the freedom of thinking it's Ginnok. The person who originally did the code to run USB host on RP2040 using a core and like almost all the PIOs tacked an amazing job adding it to teeny USB. I've been using it in that tester who saw that was using the bit bang USB host mass storage works, CDC works, HID works. So this adds a little boost converter up there to give you a nice five volts, 500 milliamps from either the battery or whatever your power supply is to power your peripheral. So it can be interesting for like, you know some ideas I came up with was logging to a USB key because if you just pull it out, stick it into whatever and the data's there ready to go. A little more convenient for having to carry around a micro SD card which like always pops off and flies across the room. That's what they do best. And then also a HID remapper, which I thought was neat and some accessibility projects where, you know you can plug in something that is not HID or you use a weird driver and then it makes it or remaps it and moves it around. It turns into a modern device because modern HID works with iOS and Android but so older devices are like kind of weird. Yeah. A lot of the accessibility stuff isn't and you know it's been around for a while. So that'll kind of modernize it. This can be really neat. So I'm kind of like psyched about this. I think it's kind of the weirdest of the bunch. But I think has the most potential to be really cool. Adafruit. Adafruit. Adafruit, the weirdest of the bunch. So tagline. Okay. Test off secret. Okay. Hello, Kidoke. We were going to roll right into questions, Lady Yura. And let's do it. You know, I didn't put our little graphic of us underneath the question mark. So I'll just go to the other ones. Okay. You ready? Okay. Can you help me understand the difference between the two PN532 boards? Okay. We have a couple. One is a breakout. So it's kind of like generic. You can use it with anything and one is a shield. So it's meant to go on an Arduino shape board. Okay. Have you seen the edge impulse integration with Arduino? What platform any plans to bring edge impulse functionality circuit path on Adafruit.io? I actually kind of tried. I had Melissa look at edge impulse and try to get it working with our RP2040 boards. And it was like weirdly hard if your board wasn't exactly the one. And a little bit of, it kind of quite figured out how to do the integration. It's a little bit like there's a magic golden path and I haven't figured it out yet. Okay. For anything, signing out the new STM32 nuts yesterday. I'm glad they went straight from, we have absolutely nothing and never will till 2059 all the way to like their new chips. There's a little bit of that lately. They were like, hey, we've been a really good customer for all these years. Can we get a small amount of chips? No, you won't get one until we all live on Mars in 2060. And now it's like, we have too many chips. Can we sell you a bunch? By the way, we have a lot of things now. Can we come over? Can we come over? Can we bring some tougher wear fellow chips? I'll check out the STM32s. I mean, I think, you know, the problem, I know that they, you know, we did cover the STM32G ones. She, I can't remember the part number a few weeks ago on INAPI. So check that out. It looked really interesting. The G-Series, I think, you know, it fits in a really interesting spot. What would the M7 be used for? Is it like a new, do we know? It's basically a very, very powerful microcontroller which is very fast. And it's been around for a while, but again, it wasn't available during the chip shortage. It's kind of a few years old. It's not that new. But it's, I haven't seen this chip even though it's been inexpensive, be popularized yet. You know, like the M721 is very popular. M751 is very popular. RP2040 very popular. But the NXP series is still a little scary to people. It's not as popular. And so it's, it's kind of fun to wade into a new family. That's what I would say. Anything that someone did with Arduino, it'll now be easier because you can use a scripting language and it has Wi-Fi. Yeah. So one of the things that scripting languages, especially Python, by them brings is you could do things like get and send things on the internet very easy. So like any type of IoT, logging, any type of like bi-directional stuff, you'll be able to do. Yeah. And this M7 is not, it's very fast. That's kind of its only thing. And it has this FlexIO, which is kind of cool. But the future ones, the ones above it, the 10th, 40, 50, start to get pretty neat. They have stuff like, you know, mipping display control, a megabyte of SRAM. It's like a full computer. You know, like 700 GPIOs. You know what I mean? It gets like pretty cool, pretty fast, very beefy, beefy chips with a lot of functionality and a lot of power. Nice. So great for CircuitPython because like we have second despair. And like the other thing is if you're on a computer and you're compiling over and over, it seems silly that you're doing that and a chip is so powerful where you can just write to it live. Like, cool. Oh, does the M7 support Adreno yet? Not yet. It does not at this time, but we'll look into it. If anybody out there is interested in wanting to get paid to do that, somebody who's interested in writing an Adreno Core with the NXP Espresso SDK, if you've done that, we have people who do lots of firmware support for us and they all love it. But nobody right now is, everyone's really busy, but we're always looking for more people who might be interested in taking on that. Maybe it's done on our new G-Jot board. Can you still use the FTDI stuff with all the newer M4, M7, and ASP32s and the NRF B2F boards? I mean, you can if you want to communicate back through USB, but FTDI cables and chips were really meant for boards that didn't have native USB. That was like back in the day. Yeah, nowadays it's like you don't need that cable because it's native USB built in, so it saves you one cable. Here's a nice little treat. Taobao says, I love all the work with the PIO USB host on the RP2040, thanks Adafruit. It's because I bought Taobao horse. That's why he goes, I bought Taobao, digital horse. I don't even know if that worked out, I should probably ask. Did that work out? You're supposed to get like a little digital horse for your tumbler for like a day anyways. A few weeks ago, you showed that you went out to experience Chinese New Year. That's right, we're onto the parade in Chinatown. You also showed that you're working on some new projects that weekend. How do you find balance in your time? Is it challenging? It is challenging, but here's the good news. We only live a couple of minutes away from Chinatown and Lower East Side. So it was a fun trip. We're going out with our family and being outdoors and taking walks. And we do that in between working and childcare. So to answer your question about how do you find balance in your time? Which is a challenging. I think right now, as I get older, we've been fortunate enough to choose the thing we want to torture ourselves with because it's all day, every day. Like everything is kind of hard and challenging and annoying, even if the best things are. So you have to just find the thing that you want to torture yourself with. And I don't mean that in a bad way. I just mean like, this is the thing that you're gonna be, what would play horse for? That you're gonna be dealing with. And so running a company, being online, being in New York, doing all this stuff, it's a weird form of torture that we absolutely love. That's how I guess, I don't feel like it's time away from anything because I don't want to do anything else. So it's a very interesting, weird situation to be in when there's nothing I'd rather do. So it's not like balancing time. It's just like, how do I do all the things and take care of all the people I want to take care of? It's more like, how do I get time instead of balance? Anyways, next. I have curiosity. Is there a timeline for the Nitro and along Bert's synth? There's no timeline with it. Right now we're working with Kelly and we have to convert some stuff to KeyCad. So next time I talk to Kelly, I'll ask if it's okay if we start to give some progress updates. So we just saw Kelly like two weeks ago. Yeah. So it's moving along, but the world is finally kind of turning back on with parts and more. She totally like gave me like the prototype and like the schematics and I was like, great, and we have a hospital. I'll see you in a good one. Yeah, that's what happened. It was like literally like two days before I screwed up. Yeah, it was like Wednesday and then it was like, oh, we gotta go have a kid. Gotta go. So anyways, I think that is the question. All right. Look, Todd did the, he said play horse friends. So oh, I guess you get to, you get to play horse friends and you take care of the horse for the day. That's nice. I like the idea of a little Tomagachi pen. So I have a browser. That's kind of nice. Make horse friend, not horse enemy. Oh, last question of the night. Are you switching from Geek at Eagle? I'm finally starting to press this. So. I don't really have time to do this. So it's not necessarily a switch for us. Lots of people on the team use all different types. Yes. Some people on the team use Cat-Cat. That's more like being able to speak the native language when you're visiting. Bilingual, you want to be bilingual? Trilingual. It's more like being able to speak the language and you go somewhere. Cause we're dealing with so many files and so many things. It's a good idea. And then that, and it's it. Thank you everybody. It's 17 on the dot. That's it. We will see everybody next week. Don't forget to code. Wednesday. Have a happy International Women's Day. This has been an aid for production. Jessie Mae, thank you so much. Put these behind the scenes. Thank you everyone who came by tonight to hang out with us. It was so good to see you on show and tell as well. Good to be back. Your is your moment of Xenor. Good night everybody.
