 Life from New York. It's ask an engineer. Hey everybody and have you passed over welcome to ask engineer. It's me lady Ada with me mr. Lady Ada on camera control We've got a jam-packed show or the lake because we had a massive show and tell a little show until Approximately 1 billion people showed up. Most people on planet earth is on the show. That's right But let's get right to it. You got all sorts of new products videos tutorials He's not out yet. Who knows coming your way, so kick it, mr. Lady Ada All tonight show the code is Laura fruit 10% an H3 star all the way up till midnight Until I remember to turn the cut off 10% off in the store for anything we have in a stock a Additional thing to keep in mind. We have a big sale on plushies So we have a bunch of plushies and folks wanted to collect them all and we're like, let's do a sale So we have a sale check that out and you be Connie. Yeah, finally happy mo Just had one of our live shows show until we'll be talking about that including Additional shows we do so desk of lady eight and great search. We'll do a little bit of recap from last week We have min York City factory footage 3d printing iron and PI new products. We answer your questions We do that on discourse, please. Please. There's a million places. We broadcast Discourse the easiest place for us to look at all your questions You can post them throughout the show or just saving towards the end when we get to all of them all that and more on You guessed it I'm just trying out some stuff. I'm doing it. I'm just trying out some stuff That's cool. I'm just trying out some stuff. Get ready. Get ready for get for the spring spring fashion Okay, so As folks are using the code they get freebies. Yes, we have freebies while supplies last $99 or more. We have a free half size from a proto although we're looking at some other possible Freebies coming soon. We still got the KB 2040s. They're currently pink, but they will not be pink after a bit So if you want the pink KB 2040s placed in order for 149 or more, it's a great RP 2040 development board with lots of stuff built in and Great for making keyboard projects. That's pro micro compatible Free PS gram shipping on orders one man going to war and while supplies last we are still getting away circuit playground expresses orders 299 or more that's right and You know just a little reminder Even though I just want to miss oh My goodness big sale on plushies. Okay. We got a bunch of stuff tonight. So we're gonna kick it off right away first up Over the weekend. It was April Fool's and we announced that we merged with ticket master for a new company called Ticket Fruit And that's how we would be selling raspberry pies. There's a lot. That's right. There's a lot of subtle humor Yeah, by the way, I tried to get tickets for the cure and I had all the browser set up I had everything didn't get it didn't get it That's how that's how hard it is with supply. She got to clicking the seeds and then it said there's not so you know You can want you can read it. So do we have it in our press section? You can read the fake press release generated by chat gbt Which did a little bit too good of a good job for that And then we also had some fun other ones a to fruit merges with amazon a design if you want to watch Our new streaming service a to flicks This is star fruit We've done this one before because we thought it was kind of funny and then of course Our merger with microsoft Microfruits so I started coming up with april fools day stuff that doesn't Anger at least one group of people this one was you know pretty good pretty good and pretty good and then of course we had a live Video from the merger of the the two companies Okay, we do some live shows We just did show and tell and it was like controller night Music and controllers. Yeah, there was a lot of cool projects Always hard to pick one and this isn't just it's not it's just i'm not saying this is my favorite However, there is one in particular that I thought Was so we had a lot of controller projects, but one was neat That I really liked was the web server over usb. Oh, yeah, that was so cool Yeah, and then you two usb acting as a usb ethernet adapter So basically when you plug it in it's like you're connected to the internet and it's the internet of cutie pie Yeah, and you type http Call in farce that's farce slash tiny dot usb And then you get a little neopixel color picker and then you can change it on the screen and it changes on the device So cool very neat and no wi-fi x2 Every single week we do show and tell look for the link in our discord That's where you can join in or you can just watch And we do that every single week some 30 p.m. Eastern time come on by It was a full house this week and don't worry if you can't show your stuff We're doing every single week probably forever So uh, you can even bring your project and show different parts of it as you work on it We do another show it's called from the desk of lady aida On sundays usually and then this sunday we did it. Uh, there was two parts Um, while we streamed we yeah, we had a technical it was really late at night, but a show went out It did go out the show went on So what did you do part one? Okay, so, um, I showed I made um an error in my dvi Pied cowbell and I showed the mistake I made which was uh thinking that us at the hdmi full size at hgi mini Had the same pinout order if they don't at all Important thing to learn so maybe a little from my mistake. You also showed off some ultra wideband feathers And feather wings. I showed off the can pico bell which did work out correctly other than one wire And then we went into the great search. Yeah, we do this segment great search Um, it's getting more fun to do the great search now because we can actually get parts So, um, you help people find stuff on digikey.com. What did you help to find this week? Okay, so this week I wanted to You know, I thought we had done a bunch of videos on fpc connector, but we'd actually kind of hand But uh, I wanted to show um finding a slim Fpc connector because there's kind of like standard thick sized Fpcs and all sorts of those kind of narrower ones Um, so I want to show how identified which ones were the narrower ones because it's not a spec You can necessarily search for so you can narrow down as much as possible and then after that do manual searching to determine Um, which connector would fit on the pcb because I need it to be like 0.1 inch skinnier Okay, um other shows and things going on so on tuesdays. We do jp's product pick of the week Tomorrow is jp's workshop and then fridays. We have deep dive with Tim, um python hardware Some interesting stuff going on this week I wanted to play a little video that jebler did and i'm also going to show some stuff from our newsletter So, um, let's go lots of new guides this week. Yeah. Well, that's that's when we get to our guides. Um, wait, sorry Yeah, we and there's a lot of circuit pi. That's so blown away by the guy. There's a lot of surprises I'm going right now So we have two new versions circuit python that you can check out Some updates have even fallen along the latest releases We're getting close to being able to focus on nine, but please continue to test it There's a sneak peek on micro python r120. So there's some bluetooth stuff that you might want to check out Up for pico w. Yeah, yeah for pico w and then, um one Project that we showed on show and tell that's also in the newsletter Um, we have this controller for our kiddo and what's neat is, uh, we had this before we saw this And then someone's like, hey, check this out. I'm giving these away. I'm showing how people make them and it's a Um, it's a circuit python board and you can turn things into controllers. So this is a fisher price Controller that that works. It lights up. It's it's six bucks and it's like a really good game controller So you can check that out and then today This is kind of our breaking news. Um, I thought this would be neat for lady to talk about So if you go to the raspberry pi site, this is raspberry pi dot org They're asking folks to test their new code editor for young people. Yeah, that just means they say young people But it just like anybody especially. Yeah, um, so young people age seven and older to learn how to write code What's neat is this is inside a browser. So, yeah, it's um, it's fully browser running So you can actually run python code within the browser. So I thought it was nice So it's got a built-in like python one time Um, just nice because usually javascript is what you would be able to do within a browser But you know, there's people have ported python to um, you know, web assembler and java or something So, uh, it's running within the browser, but they can also download the code. So what's neat about this is, um, You know, you can uh, write code For your raspberry pi or just learning python and then you can download the file. So if you go to the um, the browser So yeah, yes, you can like you can click download to download the file Um, yeah And then um, you can get the you know, the main dot py file you can multiple files So it's you know, this could be really useful for um, and then making sure it runs on mobile and it runs on tablets and chromebooks So this could be a really nice um, well featured editor that works on Um circuit python and micro python. We don't want to it doesn't use web serial yet But it could yeah, it could add and we don't want to build something like this because it's giant and complicated And there's browsers and everything so i'm glad they're doing it. Thank you Um, and then I want to play this quick video that uh jeppeler did Um It's the it was it you showed this off in the show and tell Yeah, the synth which is a part of a new feature in circuit python Howdy folks jeppeler here. I'm excited to share some of the recent work I've been doing on circuit python with the metro m7 from aida fruit um off-screen There is an i2s amplifier and speaker position to pick up on my camera And here we've got a stemmy qt board with a ween nunchuck style controller attached And I've been working on audio synthesis, which was originally contributed by github user tlmich in 2021 Uh now we can play more notes at the same time The notes can be pressed to release by circuit python code And the waveform of the notes can be directly controlled from python code So let me show you and please keep in mind i'm no musician I'm selecting different chords Adding the seventh and the ninth up to six total notes in the chord here Changing the volume up and down and the timber Delivered to your inbox every single week. I think it's the longest running Python on her renewal loader out there. So check it out at aidaforddaily.com. We don't spam you There's no Harvesting of emails from your order accounts at aidaford.com. We made a completely separate site Just to make sure you know that we are just as annoyed by spam as you So aidaforddaily is where you can get that newsletter or you can just get the rss feed or you can just read on the Web we don't care. We just want to get the information out there. It's also on github um, let's do some Open source hardware By that. I mean our guides. We have two thousand eight hundred and forty five guides late Whoa You know the team has been reviewing their own guide. They don't review the guides individually anymore Because i'm i'm so busy, but um I do check them out and they're looking really good So we've got a guide from catney for the new feather rp20 40 with rfm 69 module We've got a whole bunch of feathers coming out with different hardware attached to the end To make it easy to make no solder required Projects that are battery powered and can run in circuit python or aduino So um that guide is going and there's going to be more pages like we're gonna have our aduino tutorials In circuit python tutorials on how to use that radio module. So coming soon This is a major project. So melissa worked on this for many weeks. Um, this is a um off the shelf gunned bear So this is like a robotic bear that normally would it plays peek-a-boo and it just says like Let's play peek-a-boo and only that kind of like says like three things We have one of these for our kid and we're like this is a great robotics platform that should be modified and forced to do fan fiction Right, which is what we did. So it's uh been gutted and and you know melissa put in a Raspberry Pi with a motor control hat and a microphone um, and then tied it into the azure voice service and chat gpt from open ai so um, it can recognize your voice using like a voice recognition service and then um That text gets the voice gets converted to text the text is used as a prompt You know you say like i'm a bear and you know i'm asking this question And then open ai has the response and then the voice is spoken with azure So it's it's kind of like a cool project showing like if you're going to make um, if you're going to do something The chat gpt don't use it to submit scientific papers. Use it to tell stories and jokes Um and make little voice assistants that don't rely on You know voice assistant services, you know in the entire spectrum of like what's ai it's going to destroy us all You know nuke it from orbit. Um, or like this is the best the best thing ever Um, our point of view is like you can make things and know everything that's going on And have it do exactly what you want and make robot friends. Yeah, not robot enemies. This is robot friends Yeah, and so um one of the things I like about this is we wanted to show that when the bear was like thinking It puts the little thing up and then you control everything It can listen to microphone on or off or maybe not even have a microphone It's totally open source totally open source open source software and hardware. Yes, you know, what's going on So here's a here's a fun little video Hello there Just give my left foot a squeeze if you would like to get my attention How may I help you? Tell me a joke Let me think about that Why was the math book sad? Because it had too many problems Modern day titty rexman. Okay. Um, and then we've got some other guides Um, okay. So we've got uh, just some updates the metro m7 guide. Um, we got some of those coming back into stock too Uh, matt g who's done a whole bunch of great emulator guides for us Um, he took a little bit of break and now he's back. So this uh week He did an apple 2 emulator for ms dos Um, basically whenever we see cool emulator hardware software emulation projects, um, he just loves that stuff. So see retro Uh, we've got a guide on fog lighter, which is our, um, bluetooth way of communicating with, um, circuit python boards wirelessly, no Don't click just scroll so I can see the text Um, and then we've got a major make it glow diffusion tips and trick guide from erin So this guide, you know, it's basically like you have neopixels and you you don't want them to be little point sources You want to have like a warm glow? Um, how can you diffuse it? Well, you know, these are kind of tips and tricks that pretty much everybody has to learn over and over again But she wanted to make a guide that covers all of the different stuff that she's learned from everybody In the ate food community because I think she was asking how to diffuse something and like everybody in the meeting was like Here's how I would do it. Here's how I do it. We had like a thousand different opinions Um, and I think the generating text with chat gpt pico w and circuit python was last week. Okay, so that's the guides for this week All right, let's do some factory footage In this factory footage, we're gonna do some 3d printing We've got two things. We've got the controller that was on the show and tell it and then we got a speed up So we're gonna play this back to back and then roll right into I on npi take it away no pager You can build a usb midi controller with a custom pcb. Adafruit's cutie pie are between 40 and circuit python This hexagonal shaped midi device lets you play chords with mechanical key switches It features seven chalk key switches that are backlit with neopixel leds You can press multiple keys to produce multi tonal chords Each key is assigned several midi notes that sound good when played sequentially The code was written by john park and circuit python and uses the keypad and midi libraries It features a mode select that allows you to change scales octaves the root notes and lets you choose between playing chords or solo notes Press the cutie pies boot button to activate mode select the neopixels will turn red to let you know when it's ready The repl lets you know what options to select You can use the key switches to make your selections a handy key legend denotes the options The last option lets you choose between chords or single note playback And because it's circuit python you can customize the midi notes octaves and the colors of the neopixels John park designed the pcb in the shape of a hexagon and features footprints for chalky switches and reverse mounted neopixels The cutie pie rp2040 is soldered to the back of the pcb with header pins It uses usb c for power and runs as a native usb device So it'll work with just about any midi hardware or software To make a multicolored 3d printed case we use the filament swap technique with yellow and black colored filaments John's pcb fits inside the case and gets secured with m3 size machine screws We also printed these hexagon shaped keycaps that are designed to fit chalky switches You can make them in either fdm or sla 3d printers so you can choose from any number of materials and colors These clear keycaps were made by pcb way using their 3d printing service They're made using utr8100 transparent resin with the spray varnish option We think they look amazing combined with the backlit neopixels To get the parts code and files to build your own head on over to learn.aderfruit.com I've been playing a lot with this and it inspired me to create the music that's playing in the background of this video We hope this inspires you to use circuit python for your next midi project We're about to get on to item pi but before you do that i forget to cut the lower fruit We have plushies Get a plushie. Uh, let's go to impi This week's impi brought to you by digikini interfered is trip light By eaton. Yeah, what is this? Um, so this is what you're actually probably familiar like this. I know what this is because I asked Okay, yeah, but um trip light uh eaton is the company and trip light is a line Of power strips like power adapters. Um, and normally you're like, yeah anyways I've got lots of power strips at home right like you go to the hardware store. You don't have the one not the good ones Uh, and these were like really cool. Um, so these are actually let me give a little bit of a back Okay, so we live in the tiny apartment in new york city tiny tiny tiny Just had a kid. So now it's even tinier. It's the tiny and we're preparing because she's she's speed rounding Uh, Infant hood and so she's gonna be like she's already like grabbing everything and like, uh making phone calls and whatever the skateboarding so, um Like I have to like Neaten up all the cables and stuff like that. Yeah And uh and now I have things that can fall on our head. Yeah, and living with a lady It means unending power supplies for absolutely everything that good Then I need to find something that's a power strip That only has plugs but has usb in there Then the other thing I need is I need to I need to mount it like to a desk But but not permanently because I'm always changing everything in the ground because yeah So it needs to be I need to be able to have a semi permanent mount that I can change things because like our Ask engineer setup and everything that we do now Um has to be really easy to change very quickly. Yeah, so like right here. Yeah, so like right here. So here watch watch So so I'm gonna move my hand and I'm gonna reach down and what do I have a kid's toy because there's a crib right here So this is this is where everything is so I need to be able to have a power strip here But not have it fall. You need like a control station. Yeah, I yes, and you have to power your control station Yes, so so um, so we were talking and you're like, hey, this might be something I thought was like I saw this on the digikey.com slash new and I was like this is what you I was like, this is exactly what you're talking about. This is what I need. Okay So the series of power strips, so this is like one of them, but I'll show all of them It's like power strips But they're like power strip designed by people who actually know what it's like to need to use power strips But they mount to stuff and they mount to stuff and they're weird shapes and stuff So there's a whole series and I'm not gonna talk about all of them But you can see like there's why there's a sphere all sorts of stuff I pulled out like three or four that I thought were interesting. So this one's neat So this one has a clip and I'm maybe I'll maybe you'll actually you know It's funny if I typed in to like dolly or one of these like stable diffusion or like mid-journey things This is what I would design. I'd be like I want it to be C-shaped but has plugs on it in the usb But I want to switch and I want like a fabric thing, but then I also want something that keeps it It sticks to a thing. So you go to the front face. Yeah, because now I'll show because it's too big favorite So it looks like this. So you need to have a desk that is You know one inch thicker thicker. So it's so good for like really thick desk. It's like this like four inches It's got Three outlets on this side and three outlets on that side. It's got like a nice long It's gonna eight foot cable Yeah, and you can have one of a big chunky one at the back Yeah chunky and then on the top So this part is on the top of your desk Because it's this is like the desk and on the top of your desk you have two usb a ports and each one is 2.4 amps or total 4.8 amps usb-c And an on off switch that's like easy to get to which so you're not like underneath your table Trying to get so so this is really good for me because I'm going to use this on my workbench because I can plug in Like my oscilloscope and it's one of the so all of like my workbench tools Like like the scope has a long cable, but the hot air station has a really short cable So like I need to have I can't have this underneath my desk So it can't be on the floor. So this is the first one and this is you know, I've seen other shapes and other things, but this is like It just you know, it just reminds me a little bit like, you know, like panavis is like really handy. It's like panavis of Like power supplies. Okay, so this is the second one. Uh, so so this one, um Well, I think you give them slightly different orders. So go to the next site, okay So this is like a wide one that does sit on the floor although You can go down desk and you see it's got like six outlets four thin style and like two chunky ones But then this is like one of those boats that there's another boat that comes out of the boat But it's like a smaller. Yeah So if you go next slide The usb part pulls out and then that clamps to your desk So it has a little extension cord with four usb ports and like a separate power switch This is kind of like one part goes on the ground and one part goes up But it's kind of like a 50 50. Uh, and they have some cool weird shapes So there's this cube and if you've seen the previous, um INFIs you were like, oh, you probably wanted to like photoshop this into like a board cube But you're wrong because they also have a sphere one Like a spheroid might as well as others. Well, because it has the iris resistor So it's got this says like four usb ports and it has three Outlet jacks. Um, and then I photoshopped this into the sphere and yeah that movie sphere It's one of my favorite movies. Yeah, it is really good because you know, this The thing is maybe maybe we shouldn't have anything we think come alive. Yeah, maybe we're not ready for that yet Yes, the male Jackson wasn't that one Sharon stone Um, this is another um, what I thought this was kind of smart because you know, whenever we have a conference Like we do like conference stuff and people have to plug in their laptop for the meeting And they're always kind of like going putting their head under the desk when they bonk their head on the desk Save your head from also doubles as a candy dish or an ash tray I am a little worried the first time is going to put their diet coke in the middle That's the only risk factor, but otherwise it's pretty good. So this is what we were like this is what's on our desk That's the desk can't don't like this don't like this and see how that like wall That power strip is kind of like hanging out Like wouldn't it be so much nicer if that was like clamped onto the side of the desk? You can tell what this wants to be Yeah, so this is what we're going to replace it with so this is the this is the ion imp that I chose So it has six you want to hold it up? Yeah, so this one's really nice and look at these look at this Okay, so first off cloth cloth cloth nice fabric II so it's kind of nice This one so the other one had a clip this one actually has like thumb screws So you can go on any thickness desk because your desk is kind of Junk junk these junk very strong And and if you tighten them a little child, I can't just like I'm kind of can't pull this off And then on this side there is You know the four outlets and then two chunky ones We need the two chunky ones because the overhead has a big Power plug and so does like something else but the other things have smaller plugs And then there's you know an officer so when we're done with the show we can turn it all off And then um two usb ports so that will go to My demos because I have here, you know this little usb outlet to convert to usb So then I save an outlet because I don't have to like a usb adapter thing So this is going to be I'm giving this to you. This is my gift to you Yeah, happy birthday as I've gotten older. I have um socks and perilous I have I have different opinions about things So anything you use kind of every day Do a little bit more research and maybe if if it makes sense spend more money on it like a toothbrush You use it every day. Get a good one. Um a belt a belt, you know socks socks. Uh well socks I would say sometimes um, I mean good because yeah, I don't use the same pair of socks every day But I use different socks every day, but your pair of shoes like you shove comfy shoes shoes. That's another one eye glasses Eye glasses every day The backpack you have There's some essentials that it's like, oh, this is important to use it every day And what I didn't realize until I got older is so it's like, oh, just get a you know power strip No, don't get just a power strip. There's actually ones that um Will Change and grow with you and and you know if you're doing Shows and engineering and like living life and you know like we kind of like have to Collapse down a setup and then do things a lot And then we also need something that we can affix to A desk and then we also have to like we're going to completely change our tiny apartment again because we have a like a Little kid crawling around. Yeah, so this don't have cables on the ground anymore This will be really nice the cables and we can tie them and it's not really my birthday It's not really his birthday. I'm Very happy and birthday to you. Um, but if this was his birthday, I would give this Yeah, and it's on and it's on um digikey. There's in stock and you can get well, there's 18 So there might be less soon, but check out their whole their whole selection. Um, the ones that um, One more put together are really neat and uh, you know for ian and pi like we don't Just we pick stuff that we like this is this is this is handy. Well, this is brought to you by digikey We're not like yeah, we just things that we personally think are cool. Yeah, no one knows what we're gonna do No, it's just like we even I don't yeah, we like this and this gets rid of this nonsense Like this is going away tonight. Bye and that is this love it. I don't appear You know what um someone in chat said something, uh, you don't use it every day, but when you do When you do it matters so get luggage with good wheels. Uh, yeah, because if you're anything for if you're traveling Anything that reduces your um, it's traveling. It's so stressful. Okay. Okay, let's um jump right into new products Because we have to do a thing at nine tonight. So we're zipping along. Let's do it. Yeah All right, first up, uh, I'm gonna do this one. Um coming soon to the adford store. This is kind of a big deal because Um as twitter has melted down and not been a place to share content There's um some places online that are better and some that aren't and tumblr was acquired by wordpress And we really like wordpress. They're open source The folks that run it are super cool and they have tumblr and they're trying to do cool things with tumblr They're trying to make it an independent artsy place And so we um, we have a tumblr at a fruit dot tumblr.com and we started talking to the folks that were like Hey, why don't we do some stuff together? There's a big keyboard community there. Um, nick who's at tumblr Built a mechanical keyboard with some adford stuff and we're like we should do A custom key just like we did with hackaday and github and microsoft. So this is um, Coming out soon. These are renderings, but it'll look exactly like this. So we feel we feel okay showing what this is Um, so we're gonna have some cool projects and more that we're doing with tumblr But this is just the the start. Okay next up next up finally back In stock that we had this as a coming soon Um, because we got the pcbs and then we didn't realize the pcbs had some silk screen deleted So we ordered the pcbs. Uh, now they're back. It's the um rp2040 dvi feather Uh, this would have been um Shout out to Todd about he's been doing some cool stuff. Cool stuff. So what is this? It's an rp2040 feather Um, it's got the rp2040 chip eight megabytes of flash Stemic ut battery charging all the feather pins i squared c and analog and spi and on the end pretty cool Is a full-sized hdmi connector that has dvi output. It doesn't do audio and doesn't do ethernet just does video But uh, if you want to experiment with generating video from modern devices Um, this does actually work and when we test it on our tester We plug it into an hdmi monitor to make sure that the dvi signal is read by it Um, it uh, we only have support right now for arduino We might have support for circuit python at some point right now It's just arduino But uh, phil b pay your dragon wrote an awesome pico dvi library And you can see it just acts like adafruit gfx So if you've ever used any of our tfts or o-legs and you used adafruit gfx as the underlying library It's the same. There's fonts. There's text. There's colors Uh, there's graphics. There's you know rectangle squares lines characters All that good stuff. Um, all the bases that you need to Do graphics and drawing and as far as the feather is concerned It's basically connected to a 320 by 240 Screen and that 320 by 240 is pixel double to 640 by 480. So, you know, the pixel is a little chunky Um, but hdmi monitors every monitor supports 640 by 480. So it's a universal Supported monitor. So we all have these dead Monoliths hanging on our walls that have nothing on them And we don't want to mess with put something on it because it's like internet connected and a bunch of nonsense And it's terrible. You can turn it into art that you'd make yourself This is this is like one of the cool things and um Check out the demo that Todd's doing and and and Todd bot says I can verify the dvi rp 2040 feather Is pretty bad red. We were going to call this a feather cast, but then it would be a little confusing Yeah, um, so you can also use it with the pico sdk. They have a lot of examples The the code that we have for Arduino basically creates a frame buffer. So you you draw to it as like a frame buffer and then it outputs that frame buffer immediately If you want to have higher resolutions I think pico sdk can like dynamically generate the signals faster But you know, then you have to kind of be smart about like drawing each scan line Um as it comes out I I kind of recommend going with the Arduino library because it's simple You don't have to try to like race The h-sync and v-sync you just draw it and it outputs in the background on the secondary core Um, but the trade-off is it uses a massive amount of resources It uses I think both pios or maybe it uses at least one pio Um, and it uses 150 kilobytes of ram For 320 by 240 because that's to buffer the entire 16 bit color array Um, and it uses one full core. Um, so it you know, you can't do this and a whole bunch of other stuff But you know, you can read sensor data. You can it's demo scene time you could You know write little games, um that run on it as long as you're okay with Not having access to both pios and you're okay with losing access to one core And you don't need, you know, you only need like 30 of the ram that's available All right Sorry to show content said you lady at our team our customers our community And uh, all the things that make us all go and share and do things to get Is lower fruit lower fruit So this is the another rp 2045 that you guys are going to see a lot of these because I basically did the design for it And then on the right hand side, you know, I swap out what the module or the circuitry is Um, so the pico dbi had a dbi connector and circuitry and this one has a laura module This is a um sx 1276 based 900 megahertz. So you can use it with 868 or you use it with 915 It's kind of like right in the middle there You just pick the antenna and then in software is how you tune the actual frequency output And the gpio that are left over from the feather are connected to all the dio on the rfm 9x module You can connect either ufl connectors. You can connect a ufl to sma Adapter then connect any external antenna no solder required or if you're willing to solder a little bit These little low-cost spring antennas You know one solder point and and these antennas are very compact They work great. So this is good for laura You can run laura win on it laura win is a software stack that uses the laura protocol There's laura win stacks. I think for arduino and pico sdk Not for circuit python at this time, but you know, you can just use laura as a Long-range wireless. So these are more expensive than the rfm 69 series They're like, you know like five ten bucks more because they use this proprietary laura chipset It goes farther if you don't need that distancy or you don't need laura win support rfm 69 works really great and again, it's cheaper But you want to talk to the things network or um, you talk on the helium network or whatever That uses laura or sidewalk. I think is also laura Sub gigahertz you need to have a radio that has that proprietary radio modulation This will do it. The one thing that's nice is that we've had the 32u4 and feather m0 versions of this feather, right? So we've had the 32u4 laura and the m0 laura, but those chips are a little older eight bit micros or The samdi 21 doesn't have a lot of ram if you want to use circuit python with this radio You now finally have enough space and memory and ram to do it This has eight megabytes of flash and 264 k of ram so tons of resources available to You know make your sensor network with your laura radio All right, and that's new products Okay, a little reminder. Don't forget laura fruit is a code. We have these plushies as well You can combine them you'll take them out a bunch of free stuff that helps us pay the bills So we can pay the team for all their skills There was a couple questions lined up and then we're going to bounce right away because we have to do some night time stuff tonight Let's uh, let's do the questions and then next week. We have a massive Top secret section and everything. So we do this every week. That's why we can Keep doing this stuff. So let's answer your questions the First question I saw As I scrolled backwards. So it's the most recent one is can you use the um sdk? for the The Feather dbi. Yep. Yeah pico sdk has support for dbi just set up the pens We have an even configuration ready to go. We don't have an example code for it But if you're using pico sdk, you probably are good enough to and then I saw how many they were asking How many usb ports are on this? So there's two Three. Yeah, there's two. There's two and then a c and a c. Yeah, this one is nice And um what I for this one when I was mentioning it, there's a couple nice touches. They do There's these little rubber feet on the inside So when it grips onto a desk when you have the two chonkers, you can put one on each side Because you know how the large wall warts cover up stuff And if you if they if you arrange it the wrong way or way Um, it it bumps these the bumps the other ones off not this it goes like that All right Let me go to the other chat. We answer the question about blue fruit Do Um folks had other other suggestions invested anything that's separated to you from the ground bed shoes and tires So that's a that's a pretty good bit of advice Question for adafruit rp20 40 dvi Is the overclocking mostly when the processing is moving images on the screen? Would just displaying text be less intense for the processor? No, you have to you do have to overclock and it's the same because it's You have to output the pixels Exactly the right time To catch up with the dvi output. So it's overclocked. It's using pio. So there's you know that you overclock more the higher the resolution Um, but to be honest, you know, you kind of need to have 640 640 by 480 Um, that's the lowest resolution that most monitors will recognize. Yeah And then a follow-up from that is you're mentioning maybe circuit python on it Would people be able to do something like turtle or like logo or anything? Yeah, it would give the ideas it would act as a frame buffer and then you would use display io But it hasn't been written. There's no eta and kind of nobody's volunteered to do it. So You know when it might happen. I don't know and then another question on this if they have a 40 pin Some inch tft displays are any way to use a dvi feather? You have to go from dvi to yeah, you could use our um, yeah, you can use our tfp 401 breakout board which converts dvi To that monitor it would only be 800 by 480 at the max resolution you only yeah And it'll be pixel double. So it's only 400 by 240 Yeah, you don't see it when phil b was on the show until I had that retro thing What that risk screen resolution of that was probably about yeah about 800 by 480 if that maybe 320 by 240 All right, let me check and see if there's anything else like I said tonight We've got a uh thing at nine that we're into I think we're getting close Let me see if there's any more questions. I'll show the code one more time. Don't forget it is lure fruit That is the code The plushies are available. These are already going fast. So they will not be around too much longer Yeah, we had 101 person picked up 100. Yeah, and uh the last question of the night Um, how would I try to explain to a newbie on reddit? It's worth a shot to connect a chip to get cheap hardware store electronics to the bank 10x more for nice casing and lcd for the same chip they could buy for 10x left That does the same work You can't you know people decide what they want to do to me have made up their mind. Yeah, you made them in your mind So you can't really convince people um, but you know, maybe uh, you know send them some links to examples and and tell them that they You have confidence in them But let people explore their own way of getting into electronics I mean I started by taking apart stuff that worked and hacking it and some people like to build from the ground up Uh, there's space for everyone. Um, and then they said, you know, they don't want to seem like they're pushing aita for You know, so they mentioned other uh, sellers. I'll just do a big Like piece of advice for this because this again as I've gotten older. Here's what I've learned. Um Once you have expectations on other people or attachments to what they're going to do You're going to be disappointed. So the trick is to not Do that and so what I've tried to do Um, because I just had a conversation with someone about like open source hardware because aita fruit's going to do open source hardware Forever and there's folks who've done open source hardware and they're done with it And they're like we want a different type of license. We're tired of this. They're blaming, you know The world on things and it's and the people that are the most upset are like, well, I want you to do something That only I think is okay with open source hardware and you're just going to be disappointed So the first thing you're convincing one thing you can do is you could just show them something you've done You could be like look Make up your mind. Here's what I do. Here's a chip that I get. Here's all the capabilities and here's the type of Fun that I have with it. Here's the type of sharing I do. Here's a community And instead of trying to assume people will be convinced on something I'm I'm at the point where I'm like, you know what? I'm just going to show the best thing that I'm proud of Um, and the best thing that I think l'more is proud of or the best thing the community would like to see Because if there is no such thing as money or time or anything, what would I do? I'd want to do this. I want to have something that I'm proud of forever I don't think you can convince some people. They've already made their mind Um, and then next up, this will be the last one seeing arduino we arduino build an uno r4 with the renaissance controller Is there uh anyone else thinking of exploring higher spec renaissance micro controllers for hobbies development? It'll be interesting to see. Yeah, I don't know. I mean renaissance doesn't have they invested in arduino So you're definitely going to see arduino using the chip They don't have a big headway into the american market like they're huge in japan, of course Their japanese brand made of very many they were conglomerate of multiple japanese chip companies It'd be interesting to see how they interact with the american market and what what they have to do to do so It'd be it's it's fascinating. I mean their chips are extremely popular for automotive Um, especially yeah arduino like you know depending So, uh, this is super insidery baseball because i've been writing about arduino for decades and now you know I work at eta fruit. So I don't really do the same editorial because we'll always be considered like a competitor or everything So just like, you know ask an engineer talk and stuff like that. Um, so arduino Is doing pro and that's in the like industrial space. It's not open source. It's like this is what we're doing for industrial control This is what we're doing for like factory like, you know industrial iot and then um Last year they got 30 something million in funding and it was renaissance and bosh I think with it and there was like another party and so you're definitely going to see those if those companies wanted to Figure out if there is a way to get into this this market like dev board market or whatever. That's the way they're going to do that anyone Make libraries for stuff arduino day. They ask people to rewrite their libraries. You can apply. Um, we'll see it's interesting I don't know I don't know I can't tell the future and I can't tell you what to do. Yeah, so Um, I'm looking forward to seeing people do projects with more low-cost microcontrollers and doing more than better and doing open source hardware and software um Damn some questions lady. Okay, we did it amazing. Okay, so that's our show for tonight. Thank you so much everybody special Thanks to zay. I think he's behind the scenes Um doing stuff in slack. We thank you very much For joining us. This has been an ad for production. Here is your moment of zener. See everybody next week. Bye. Bye Good night, everybody
