 Live from New York it's Ask an Engineer. Hey everybody and welcome to Ask Engineer. It's me, Lady Ada. The engineer with me is Mr. Lady Ada on camera control and microphone and also Emperor of the Known Universe. We're here at Adafruit what? We're all in charge of the universe. That's true. We're here at Adafruit our downtown Manhattan factory. We do all our shipping, coding, assembly, manufacturing, and more. It's all happening here. The factory is quiet right now because everyone's home but that's because we've got an hour packed full of the latest and greatest in maker open hardware software coding and Python burping and news as well. Why don't we kick it off Mr. Lady Ada and tell them what's on tonight's show. On tonight's show the code is unexpected. This is celebration of all the cool boards we're putting in from unexpected makers. So 10% off in the Adafruit store all the way up to 11.59 p.m. Eastern time code unexpected. We're going to talk about some Adafruit Live shows and more including show and tell. Thanks JP for hosting that. Time travel, look around the world makers, hackers, artists, engineers, and more and speaking of we have a new segment we're going to be doing probably for at least the next 18 months it's called ship shortage. Stay tuned for that. Some retro tech which we showed a little bit when we kicked off the show from the mailbag a special extended version of a song by request. Help wanted, go to jobs.adafruit.com the poster skills or if you're a company that are looking for amazing makers to help you with your company or project posted up there. Some New York City factory footage from here from the Adafruit factory in New York City. I am told that we are classified as an advanced manufacturing company. That is the way people in New York who are interested in getting reelected are talking about things are like advanced manufacturing that's where it at. You guys are advanced manufacturing so we're advanced manufacturing. We're going to show some photos from our advanced manufacturing. 3D printing some cool projects from now on Pedro including probably one of the most ambitious projects we've taken on yet. You will see that very soon. Some new products we answer your questions. We do that on discord.adafruit.it slash discord or discord.gg forward slash adafruit where you can join all 30 for a thousand of us. All that and more on you guessed it beep boop asking an engineer. Okay so first up let's do a little reminder. Help us pay the bills because things are expensive. We love paying our team. We love paying the bills. We love we just did taxes just like all of y'all in the US probably. It was a chunky bunch of taxes so help us pay the bills and pay the folks for their skills and use code. You get some free stuff on the way out though. That's right $99 or more you'll get a free perma proto half size breadboard handy for taking your projects from a solderless breadboard and making them permanent. I use all the time $149 or more you get a free STEM and QT board or controller or breakout. We've got a range of like about 20 different boards that we give away different sensors and devices make an account and we'll make sure to get you a different one each time and then $199 or more you get free UPS ground shipping in the content of the USA. Don't forget make an account on adafruit.com verify it means just clicking an email and then set up two factor authentication. The reason is that is how we sell high demand products including the Raspberry Pi. If you look at all the Twitter accounts and Raspberry Pi bots and sites that says here's who has Raspberry Pi's we do but when we release them you have to have two factor authentication and more and it looks like that's the direction a lot of websites are going to some are doing things like charging a lot over the amount of a Raspberry Pi we're not doing that some are saying you have to be an existing customer from the past we're not doing that you just have to have a two factor authenticated account that's good security practices anyways so this is helping people do that as well but that's what we're doing we're also filtering orders so yeah that's not the only thing yeah of course we do that we do that with all orders you do your part we'll do our part yeah we'll get you Raspberry Pi and today you know we put in some Raspberry Pi's and it was neat to see educators people that have been waiting for a really long time they all had a fair shot at getting Raspberry Pi's and they were able to so we do a bunch of live shows including this one but our live show that we did just right now just a few seconds ago we show and tell special thanks to JP for hosting it this week next week known Pedro hosting it and we're going to watch as soon as we get home after this we're going to watch the show and tell because we're setting up the show so if you want to every single Wednesday 7 30 p.m. hang out in the discord we put the stream yard link that allows you to just very easily use your computer and webcam and all the things that we've all been using for the last couple years in some way to show and share your project whether it's Lady Aida and myself or JP and now Pedro we'd love to see you join us and you know a lot of people ask like how do I get a job at Aida Fruit a lot of times when we work with remote team members it's through them showing and sharing their projects doing open source and being part of the community so that's a fast track way to do it on Sundays we do Desk of Lady Aida in fact this week we're gonna put a couple extra things in Desk of Lady Aida we're gonna do IonMPI on Sunday but every Sunday we do Desk of Lady Aida hacker o'clock which is like usually eight or nine what was in part one of Desk of Lady Aida well we showed off this cool Sony record player yeah and I think we showed off the schematics and and we took it apart a little bit we kind of showed some pieces and parts I also showed off an upcoming project the ESP hole which is an ESP32 S2 TFT Feather version of the Piehole JP is going to be documenting that thanks to JP I also showed off a STEM QT board I designed and also a USB PD chip that I saw on a breakout board that I might investigate okay then we did our probably most popular segment on maybe even all of our shows now from Desk of Lady Aida we're in the world is that part I need the great search with digi key native fruit Lady Aida helps you find the parts you need Lady Aida what were the parts that you were helping people find this week okay this week um I worked a little bit more on my RS232 feather wing and I decided I had so much space because RS232 conversion is so simple that I thought hey let's get a RS485 chip on there as well and so I searched for different RS485 transceivers full and half duplex common packages available and I found a couple good options okay so we'll be doing the show this Sunday we'll have a bunch of surprises and more and that's when we'll be doing iNPI all right JP's product pick of the week was this week we're gonna play it um a little programming note JP is not going to be doing John Park's workshop this week probably be returning next week but we'll give you a heads up here is the product pick of the week this week a little jewelry box hey look there it is it is the Pie UART USB console and power add-on connects right on to these first headers of the Raspberry Pi fit that on there and just press down so I'm plugging in USB-C there and then I'm going to flick on the power switch what I'll do is connect to it using a screen so I'll type in my username password which it's going to tell you I haven't changed now you can do things from here like adjust configurations maybe this is a headless setup let's say edit the config and there we go we can go in with nano here go maybe uncomment some of the overscan stuff for HDMI if you're having HDMI issues it might be impossible to see it on the plugged-in monitor but you could go in here make your changes this is the Pie UART it is a console and power add-on for Raspberry Pi and we also do circuit python parsec this is a little bite-sized piece of circuit python that you can code along with gp or you can watch the highlight and this is this week's for the circuit python parsec today I wanted to show you how you can use a bitmap graphic with transparency inside of circuit python so this uses image load and I'm using display i o to do a whole bunch of other stuff as well as vector i o but what I've added here is a new little function called add clown so what I'll do is remove the comment from this and a resave this code to my board and what you'll see is when it restarts we will have added precisely one clown hey there's a clown and uh oh he's a sad clown but the cool thing about this clown you can see is that since I have the ball bouncing around behind him it's pretty easy to tell that there is transparency going on sort of like an alpha channel if you're used to modern graphics but what's going on here is that there is one special color in this image which is considered to be the transparency color what's happening in the code is that anywhere that the index zero color so the first color in the palette which happens to be magenta is going to be knocked out it's going to be rendered transparent in my function what I'm doing is loading in a bitmap graphic that's that clown to dot bmp then I'm setting up with image load the image as well as the palette what I'm doing is with pal dot make transparent zero I'm picking the first one index zero color which is the magenta and making that the transparent color then I set up this little sprite as a tile grid clown dot tg is tile grid clown image and the pixel shader and then I append that to my main group and then I'm setting it in a particular place depending on the call that I send to this function so if I send it now another one add clown at 70 70 we'll get two clowns on there which are going to be at the positions that I've indicated so there you can see it's a really easy way to create transparency and so that's how you can use transparency with a bmp graphic inside of circuit python and that is your sad clown circuit python parsic okay and then don't forget to tune into deep dive which it really is a deep dive Friday the 2 p.m. Pacific 5 p.m. eastern where tim foamy guy will go into the deepest parts of circuit python and show and share them with you lots of display stuff that's right time travel some reminders some things some news and more we travel to through space and time together and here we are so first up a reminder eight a box we are still working on it thanks for your patience we try to do four eight a box is a year we change it to seasonally because it didn't make sense to try to hit a specific date because of the part shortage and more and we're like yeah you know what this one's going to be winter spring we're just going to call this next one spring so that's just the way it is if you all see what's going on in the world right now and we're going to talk about this in our upcoming segment ship shortage yeah so there's parts of the world that are in lockdown the boats are sitting out in port there's a lot of disruptions in every possible way I also think because we saw this article about the the fox con that never happened in the US in Wisconsin and you know one of the things is there's a lot of promises that were made years ago that just weren't kept and it's been a few years so I think there was this idea that we'd have certain things like oh we're going to have all this battery production we're going to have this chip production a lot of it didn't happen and now people are like wow like there's just not enough stuff for what we need and the demand is higher we also have a very disposable society there's a lot of things that go into it's not one thing so anyways we'll keep everyone updated don't worry you don't get charged until we ship a data box we'll continue to update our site we'll do this on our shows we'll keep everyone in communication once again we thank you for your support we are completely full with a data box some people once in a while will pause or cancel and then someone who's waiting for a slot will immediately go in and that that waiting list is pretty long so um you can do that on nativox.com so mailbag this mailbag is a little bit different oh yeah a little bit different this week so you know there's a lot of ways to get ideas but the way that I know how to get ideas is to get a lot of ideas from a lot of different people in fact I like um chatting with folks who don't have the same opinions I do I like all the angles covered if if lots of different people are coming to different things so we have a very open way of communicating so people come up with ideas all the time they also send nice emails to us so this came to our contact form I really like this it's from max hi can you please tell lady and never to stop singing her little new new new new anthems during the product videos I've been watching it for four years and it never gets old she has uh has to continue doing it it's a monument she is so uplifting so I'm so excited about the new product I am I am pleased to debut the one minute long new new new song that we're releasing we're dropping it today and it's one minute of your listening pleasure here it is and thank you max for the kind words that inspired us to make the song didn't make it to this grammy it's but the next one yeah thank you max that was beautiful all right so uh next up our newest segment that we're going to do and we're going to be doing this every week from now on uh until there's no chip shortage which is a little unknown 18 months here we go chip shortage every day it's a chip shortage in every way lady what is the chip that you would really like to have that is currently not available okay so this week's chip of the nonexistence of the week is the Bosch B&O 055 makers engineers and roboticists love this chip I miss you so much it's a combo at samd 20 with like some Bosch I think like a bmx 055 or something uh nine-off sensor and it does fusion and it like emits all this data that's like pre calculated um it can uh pre cal you know it does a calibration for the magnetometer we have a breakout for it people love it I I love to keep it in stock and I can't um and we have hundreds of people who are um these rabbits I can't tilt anymore they can't tilt people rabbits can't tilt anymore I just love the sensor we use it for so many projects and I'm so bummed not only is it unavailable and there's a shortage what happens when you go to digikey and order it you can't even back order it um there's no estimate of when it's going to come back it's been it's bad it's it's this is one of the most um unobtainiums of unobtainiums and it's it's a bummer there are there is an nxp nine-off sensor that we have in stock you know st has a nine-off sensor that's also unavailable but the bnx 055 kind of it was a one stop solution to um doing orientation measurements without a lot of calculation so I'm I'm saddened to say that it is affected by the chip shortage um we have you know 1000 order but um we just don't know when we're going to get them so if please mr scrooge I'm just a street urchin if mr bosh is listening so please mr bosh so um here's the thing if if you could I know you would if you had like wishes you'd wish for more wishes because that's really supposed to but you you was like world peace and you know everybody's happy uh everyone loves themselves love each other but uh let's say you had but let's take a gut through all this well let's say you had to do electronics based wishes for getting us parts yeah if you could talk to uh miss bosh I guess that's the owner of the company I seem so yeah um how many chips would you want and of what ones what do you want well I've got 12 000 ordered I'd love to have them but even another reel of 4000 would really help because the moment we get any they sell out instantly and then I can't get any for another you know six months or more and it's it's such a bummer okay so um we're going to do this every single week this is just one of many for the chip shortage uh we'll listen to y'all what you need we'll try to get the word out to the manufacturers um I think this is the next stage that we're in which is like begging come on like like like just desperation just we just want to let everyone know like this is real this is happening um we're sending so some of our team members at Adafruit uh you know we have a little stand-up meeting every day and uh they said yeah my friends and family are now asking me what's going on with this chip shortage and uh then some people who have Adafruit on their LinkedIn there's random people contacting them asking them to find these chips here and send it to them so please no we have like random friends of random friends of random family members contacting us asking us for FPGAs I'm like I do not have a stash of 10 000 FPGAs in my basement there is like this other thing which is like nice try there is like oh hey Phil I know I haven't talked to you in 10 years in the last time I was really mean and like stuff but anyways can you give me some tips I tried to push you off the cliff can you give me some chips and I'm just like I don't have the I wouldn't be able to even if we had them because that wouldn't be fair um nice to hear from you though um you know chip shortage bringing people together so that is this week's chip shortage tune in two years from now from our segment chips to plenty um so next up let's go to retro so we got two videos and we're going to show a demo um maybe I'll try to the demo while we're showing the first video so first up I have a collection of retro input devices and I don't believe in throwing out beautiful retro devices even they don't work with modern hardware because I live with Lady Aida and she can make it work with anything so the next thing you're going to see is a spaceball 2003 and it's a really cool 3d device we've had some photos and more but this is the video of getting it running and working Lady Aida what is this would you like to touch my spaceball this is a spaceball 2003 it's a 3d user interface device so people use these kinds of things for CAD this one's pretty old so it's got a dc and rs232 connection but I'm actually testing out this fgdi based rs232 cable and uh so you set me on a path to maybe get this working in python and um it actually works pretty well I got the button presses working you can detect all the buttons and when I touch the ball you can see it prints out um the xyz coordinates and then like this vector as well I put that code up on just on the github and also you've got some really cool photos and videos of this on flicker if you search in the aida fruit section for spaceball okay and next up um a long time ago we released an album this is frequency and it's a pink album and all of our songs are in soundcloud if you want to download them we made these available for everyone um and you can buy the record we still have some and one of the things that I've been trying to find for like a decade actually more has been this um sony record player and so this is codename flamingo um it's a portable record player um you can twist the stand on this you can put batteries in it um you can mount it on the wall and the cool thing is the record plays horizontal and we'll do that in in just a minute um you can also play it you know sorry vertical and horizontal and the needle goes up and down and it's just this beautiful amazing thing right at 1983 right when things were changing there's a headphone jacks out it even says hey go record something remember that a version of a company that said record music this is like the pre yeah preintellectual property sony it plays uh you know different sized records different speeds and uh one clever hack that they weren't supposed to do some of these can broadcast on fm so you can broadcast it to your stereo and so they were even doing like you know bluetooth wireless before before you know bluetooth wireless for a lot of these things um it does uh plug into the wall if you wanted to and um one of the things i'm going to try to do is we have a photo set that we're doing i'm going to try to convince sony i collect weird sony stuff so this is like you know the sony little round speaker this is very modern this is a bluetooth speaker um and it does all sorts of stuff and then this is a little portable speaker and i just like sony stuff quite a bit and let me see if uh i can get this going here so this is the record player and i think what i'm gonna do is uh go like this is that the power supply what that's the right power supply plug it is now yeah just watch out because it's center negative not center positive yeah so here it is and uh hold it up and i have a little feet on here but these go these fold it like this and then i'm going to put this in i'm going to turn it on and now i'm gonna put the record in and put the record in you slide it in and then you lock it in place and you could either play it like this play it like this i'm gonna play it like this and lady if you could plug in to the headphone jack and we'll be able to hear this and then press power on the speaker this is a modern new speaker that's plugged in and then what i'm gonna do is sony brand and it's sony brand i wanted to bring on baren so let's see if i got it going yeah the sony vertical record player that's this week's retro all right help wanted yeah someone said in the chat that's a big cd so this is a neat one this is a theater group and this theater group is looking for chained led panels for theater super titles maker and coder needed this is at the performance space in new york and uh all the details are on jobs at adafruit.com and you can check it out and if you want to help out a very cool music theater and performance theater and art theater you could do that probably could do it remote but that one might be better for the new york area so how do i turn this off what oh it just turns off automatically eventually great and that's this week's help wanted okay we're gonna do some python on hardware news are you ready landing yes i am ready okay this week we have one big bit of news that i wanted to talk about picon us 2022 is going on in salt lake city and if you check out our newsletter we have a bunch of details of course you can sign up adafruit daily you can also check our blog this is the blog post we have looking forward to picon 2022 picon 22 is coming right up the conference is april 27th next week to may 3rd as a pre-conference summit and their sprints with catney melissa and jeff from adafruit they'll be doing the education summit april 23rd catney will be giving a talk at the summit called simplicity and fun learning with circuit python will also be hosting us welcome the circuit python event um we already have everything up at least most of it uh on github so you can follow along even if you're not going to be there you can download all the examples and stuff and uh you could see all the work that we put into this so it's easy for attendees to learn circuit python and more and you can do that as well in our newsletter um do check out the latest circuit python show ali from sparkfun when is it it's really good interview you can learn about her journey and how she ended up at sparkfun things that she's doing there and a lot of interesting insights on what's going on in the miami tech scene um it was a good video congrats paul on some great interviews with the circuit python show which we have nothing to do with um which is great that's what you want you want to make something so other people can make something with it um and uh our newsletter has the usual i did like this keyboard this is like a courting keyboard that you could just do with a pico i like the axolotl and uh circuit python so i thought that was that was that was pretty cool um so look at the lizard what you want to look at the lizard i don't know what it is it's a look at this weird animal yeah you could tell it's it's somewhere on the evolutionary uh chart yeah um and it just decided to stick around there so uh anyways lots of keyboard stuff and more this week but uh the big news big highlight is please check out all the stuff that we put together for picon 2022 hopefully we'll see some of you there um even if we don't please check out the things on github and uh thank you everyone in advance for the folks that are going especially the adafruit team this is one of the first events that we're going to and so we're looking forward to doing more soon um don't forget you can sign up on adafruit daily adafruit daily dot com we don't spam we don't harvest your emails we didn't do anything that it says completely separate site because we didn't want to tie it to your adafruit store account and we deliver that every single week right next up it's open source hardware time do you know what friday is i think it's so open source hardware summit it's the open doors artworks this virtual this year um and we are a sponsor we have some team members tuning in virtually i do like the artwork in it this year and because we bought tickets and we're a sponsor we got a goodie bag so this is the part of the show as one does on youtube it's kind of like an unboxing is it i'm bagging i'm bagging this is the tote bag everyone needs a toting it's the law um all right tell me a show yeah so why don't you uh tilt the overhead well on one hand i want to tilt on the other hand i want to show off individual things yeah so let's uh let's go and show so here put first let's let's put this underneath here okay and show this off so here's the art why don't you do this okay so first off there's this cool resistor capacitor art yeah very cool okay and i think you could still get a goodie bag um here is a parts pack from spark fun okay classic red box red box from spark fun i think i think you want to pack this up because it's just like a big more big red box big red box yeah you can always i'm working on it okay comes with a bunch of parts cables i love these jumper jerkeys as pyrone calls them headers very useful and a card and i think this is a sticker a vinyl sticker a very nice vinyl sticker more headers and of course the box itself is also very useful yeah making projects that all right now let's start taking out the stuff that it came with okay digikey included an innovation handbook yeah we're in there which is cool it has lots of pinouts and color diagrams it's a really great book and then tons of gridded notebook for your schematicing and charting and graphing and ideasing okay okay what else um there's a mug can we open a hardware summit it's kind of yellow bug and this yellow it's like an atom and it's like a and p and junction maybe i don't know exactly but it's cute and it's a mug i like it's yellow it's a shiny happy color okay when you're not showing stuff let's put something there so it's not dead space yeah okay there's this minnow iFixit kit which is kind of handy it's got a little bit of everything it's for fixing gadgets around the house it's got the nice uh screw top so oh cute gift twenty dollar value um seat studio this is a little uh sleepy mask supply frame this is a webcam cover from alpine glow there's a ruler with a neat golden and blue teal color effect and some papers um stickers from the open hardware summit so it's hardware logo nice logo no patent pending yeah okay some more stickers ash park stickers hackaday stickers lulls bot pulse sensor tendy yeah i think i fix it a little a mini sticker pack from shop bot hold on there's a lot of stuff going on here what else is in there um a pin yeah i think that's a bottle opener bottle opener uh haxter sticker um i think it's also open hardware summit logo's another hackaday nice logo on the hackaday thing and i think that's it okay i miss something no that's everything okay all right so you can go on bagging ashford.org and you can um still sign up and get tickets and uh definitely check out and see if there are still goody bags left we are an open source hardware company to prove it we have two thousand six hundred and fifty eight guides and lady eight is going to go to sleep that's it shows over it's actually really comfy by the way she's saying too much this is very soft yeah yeah feel it yeah it says loading that's kind of clever it's soft all right it's actually very comfortable so we have a bunch of guides yeah and uh this week um we'll show the videos with them um oh you're right that is nice that is nice told you okay sorry putting all the stuff away and the mug don't forget the mug okay yeah cool it's funny it's like i feel like i should be wearing you know a mask too i guess this is um hey everybody the cdc changed their mind can i look a little bit like a robot yeah okay looking good okay you want to go through these guides yeah no rush um two thousand six hundred and fifty eight i was feeling time where you're doing yeah yeah um take it away okay so from lis we've got the um we've got a video also it's the glider controller um i was playing uh glider again i haven't played glider since i was a kid it's a fun little game with only two keys where you control a paper airplane through this beautiful monochrome um apartment uh it's a classic mac game i thought it would be fun if we made a um a controller that was actually a paper airplane i thought it would be a good little circuit python project because it would be wireless we would use the um wireless ble support that we have in circuit python and showed off we've also got a guide for the new esp 32 s3 feather that's a new feather it looks just like the s2 feather but it has a dual core more s ram and it has ble support it's the s3 is pretty new arduino support is still in release candidate mode circuit python support is still kind of happening um but this chip is is is coming around and so um we do recommend checking it out especially if you're interested in uh a dual core esp 32 basically the original esp 32 but with native usb and a couple more peripherals and then finally we have our 3d printing project of the week it's a phil b painter dragon uh plus roos brothers collaboration it's the connection machine raspberry pi case or if you don't have a raspberry pi you can also use a pi pico um it looks just like a connection machine five i think or four and we went to moma with an and uh i shot this video in 2018 and we said one day we are going to make one of these for our desk and it happened yeah it's really close um it's cool how um you know we could 3d print something that is desktop sized but you know it has tons of red leds and we got some cool patterns going on it so um it's a good build yeah and then i wanted to play the video from lis yes it's time for main york city factory footage from the advanced manufacturing factory adafruit advancing the manufacturing yes always forward advanced and it wouldn't be the main york city factory footage from the advanced manufacturing factory adafruit unless we showed some of the uh time lapse of the disney building going up uh i have breaking news disney's leaving florida and they're moving to across the street from adafruit they specifically said we're moving next to adafruit that's what they're doing so i know they've been in the news so well you have the light parade already that's right okay neopixels 3d printing all right we're going to play these back to back this is a connection machine build and then we have a really cool uh dragon like wall hanger uh speed up so see you on the other side hey what's up folks in this project we're making a replica of a connection machine with the raspberry pie the connection machines were a series of super computers from the 1980s that featured red leds in an iconic cubic enclosure design we were inspired to design and 3d print a case for the raspberry pie and used adafruit's charlie plex led matrices we also used black led acrylic to diffuse the matrices and design them to just slide into place the audio visualizer demo features interactive leds using the audio levels from a usb microphone this project uses a total of eight led matrices and two i-squared c buses random blinky lights are a classic staple of retro computers depicting their cpu activity these 13 by 9 charlie plex led matrices are daisy chained over i-squared c and they're powered directly from the raspberry pie this project can also be powered by the low-cost raspberry pie pico rp 2040 with circuit python you can run the blinky lights demo or write your animations using the led driver you can use jumper wires to easily plug in wires to the headers on your circuit python dev board the audio visualizer and chasing led demos were written only for the raspberry pie the enclosure can be 3d printed using your favorite filament links to the files are in the description you can set the i-squared c address bus by soldering the jumpers on the back of the driver board this project uses a total of eight led matrices and two i-squared c buses be sure to check out the learn guide for full step by step tutorial on building this project the enclosure pieces are attached together using machine screws the led matrices snap fit into these little pcb frames that are secured to the enclosure the case features built-in rails for the black led acrylic panels jumper wires are plugged into the header pins for easy connectivity a right angle USB adapter is used to run the power cable for the raspberry pie to a 5 volt power supply a separate pcb mounting plate can be used to secure the raspberry pie pico rp 2040 board to the bottom of the case the back of the cubes feature snap fit panels and feature vents to keep your raspberry pie nice and cool we hope this inspires you to check out circuit python for your retro inspired builds thank you for watching and be sure to subscribe for more projects from adafruit watch 3d hangouts with no major every single one say let's do some new products big news um these were out of stock for two years but now they're back in stock with the micro bit v2.2 small change to these and like it's kind of updated it's kind of not updated they were exactly the same as the original micro bit v2s but the chip that is used for the usb to um serial and programming capability like the um l and ldap chip dap chip the whatever they changed the model because you know there's a chip shortage so they found alternative works exactly the same as before so if you're looking for a micro bit v2 this is the one we have the bare one not the go kit this is the only model we have in stock right now okay next up um we have we've actually already stocked the rgb w version of these mega bright neopixel compatibles um with warm and cool white leds and this is the one with the natural like neutral white leds took us a longer to get um but if you want like a three watt led version of a neopixel on aluminum pcb uh these will do the job they work just like neopixels you power them from five volts but they just got like a massive ass led on them so uh just you can see you can chain them of course it's one pixel per uh comes with cables of course you're going to replace the cables and then you can see this like huge uh led chip in the middle with a ws twenty eight eleven driver and then it's aluminum backed pcb for heat sinking oh and then sorry if there's there's a big heat sink yeah okay okay next up next up uh this is fun this is a curb cut 64 by 64 led matrix it's a hub 75 matrix just like you'd expect but it's got a trick on the back it doesn't have like a flat corner side it's not meant to go um next to other panels on a wall it's actually great for making corners and it's curb cut on all four sides so that you can make it into like cubes and other shapes otherwise it's uh identical to a hub other hub 75 uh 64 by 64 led matrices comes the power cable comes with the 2 by 8 idc cable um it's only only difference is the plastic it's 2.5 millimeter pitch uh this is showing you know three together um making a corner so this would be great for making cubes um or other shapes that you know you don't want to have to remove the plastic it like this is not even this is how together with tape to you'll still want to have a mechanical structure behind it um but you know if you want to make it easy to make um cubic shapes or rectangles or whatever have you um these curb cut panels are great and they'll they'll line up quite nicely on the edges you'll get a nice clean seam uh next up from uh pymaroni or pymaroni we have the servo 2040 um this is a rp 2040 based board that runs uh c plus plus or uh micro python and has some pio code that is designed to run uh up to 18 servos very cleanly so great for like hexapod or other robotic projects or automatons where you want to drive a lot of servos very uh cleanly you provide 5 volt power externally um program it over usb it's also got some rgb leds uh and some sensor inputs for the analog input ports um it's fully assembled got some qt port i think two buttons um you know big cap um but otherwise it's it's basically designed specifically for servos or you know anything that takes a servo input i guess you could also use it for driving other pw mable devices um but i think this will be great for roboticists who want to um you know make uh humanoid or or arachnid like robots okay and then um starting the unexpected maker tour here we go yes we've got three uh esp 32 s three boards from unexpected maker this is i think the teeny pico version um which i think has eight megabytes of flash and eight megabytes of ps ram um all of these started us the usb native capable esp 32 s three which is as we mentioned a dual core esp 32 board so it's got wi-fi ble two 10 silica cores running at 250 megahertz uh 240 megahertz uh 500 k of s ram and then of course external ps ram um got some extras on here like um you know a little neopixel in the corner there i think a battery charger that you can solder a battery onto um lots of the gpio pins uh and it's pin compatible with i think with the teeny s two so if you have one of those uh you can use this as well so very powerful little chip here's the feather s three version so it's got two stemmy qt ports uh with power control um usb c uh dpio it's feather uh feathering compatible although do watch out the pin numbers are not kind of the what we'd like to use for our classic uh feather configuration i think it's got 16 megs of flash and uh eight megabytes of ps ram although check the specs for that got neopixel two regulators um and tenant all that good stuff okay and then uh the next one yeah and the last one is the pro which is uh get cast-layed pads a lot more pins um it's got a battery port on the end if you do want a battery port i think this also has 16 megs of flash and eight megs of ps ram uh it's got stemmy qt port and buttons it looks like it's a little slimmer than the feather it's like this it's like the slimness of the td pico but like extended out uh so it's got a ton more pins uh looks like it's got a couple ground pads as well so it's got like the most pads uh if that's what you're looking for yeah all right and then uh you know they all come with these cards and they show all the yes and more and these are and these yeah they're all running circuit python i think there's also micro python support and of course arduino supports coming um it's it's in the release candidate mode um these are the ones that have the um updated wi-fi so they're gonna have uh you know good wi-fi connection there were a couple that came that went out earlier from um other vendors that didn't have the wi-fi fix but these do so if you're wondering uh these have the wi-fi fix so they're got they've got solid wi-fi and bluetooth connectivity okay and then the star of the show besides you lay data our team here at adafruit and around the world our community our customers this cube oh yeah yeah and that's the gear where the cube here let me uh let's zoom in go go this way you can say yeah yes this is just held on with like tape i think but um you can see these curb cut these are right all right the star of the show this week is it's the um wfl external antenna version of the feather v2 it's basically the exact same layout as the feather esp32 v2 but instead of the pcb antenna module we're using the wfl antenna module it's great is that it's got um you know c an fcc certification and you can attach an external antenna using the built-in wfl connector which i will show it's got usbc it's got an esp32 it's got um eight megs of flash and i think two megs of ps ram um it's got uh auto reset it's got a reset button and a user button it's got um a stem iqt connector with power disabling there's a neopixel battery charging all the stuff that you love about the feather esp32 v2 we upgraded this version um pinout is is nearly identical um but of course there's there's just more memory more flash more everything um and there's also more labeling because the module is smaller and we got to cram more stuff in because of that i like the little a different logo it's yes well it's i know i can i did that on purpose i think i like it let's just say i did um so i'll just show what's what's going on here because it's a little it's you want to be close so like i said it's the exact same version of the board as the feather esp32 um v2 except normally this would be an antenna but you see there's actually no this module is just cut short usually there's a pcb antenna but there's no pcb antenna instead the the pcb underneath is visible and this is a wfl connector so this can connect to an sma adapter here or uh i can grab this is a um from digikea i just picked up a uh this is actually a bli antenna but you know 2.4 megahertz will work fine for wi-fi so why is this good let's say you want you know much better antenna than the pcb antenna um you can do a directional antenna if you're putting in an enclosure um that will block the rf signal you can um you know use this to have an external panel mount but mostly it's for people who want a better antenna than the pcb antenna which is you know it's a good antenna it's not bad but um an external antenna will will get you more gain and of course you can have it farther away from electronics especially if if the rf is a sileto affecting um your signals or something it shouldn't but you know you want to have it far away um you can do that one thing i will note because i even i got confused by this it's not a ufl connector it's a wfl connector it's smaller than ufl this is a it's also called an mhf3 or an ipax3 it's kind of a third version of uh what you know what ufl would be called version one this is smaller than that um so we'll be getting adapters but for now in the um product link for this product um i do link to a place you can get uh you know these sma or rpsma wfl adapters and also on digikey there's this antenna that i've tested and uh works just fine even though it's advertised for ble it's still 2.4 megahertz um and it's a fine antenna so um you know if you like the feather esp32 or esp32 v2 but you want an external antenna um we now have one in an fcce module format um with a wfl connector that's easy to plug in external antenna okay um don't forget the code is unexpected you can use it on all those unexpected maker products yes and congrats unexpected maker on a fantastic debut with all of your products and we are doing a community thing together where we build together in the open and more people can do more things together so i'm excited to see those products in this store so we're going to jump right to questions um because we got to get out of here early this week made for dot it slash discord questions or some lined up lady i'm going to speed round it with you go for it and here we go uh first up i posted up the video the chip shortage one of just the soundtrack if you want to listen to it okay cool um and uh that's for folks who wanted to put it on repeat shortage that's right okay any suggestions for controlling led animations over bluetooth i know that there is an esp led animations library um you know we do have one in circuit python 2 i guess it depends on how complicated you want to do for ble but i would you know i would use things existing ble you know rxtx project that just sends data back and forth and then check out like fast led and see if you can just control it from that i think that we we've got a project or two with um fast led or led animations that's controlled over wi-fi do the new esp 32 boards do the esp now wireless communication protocol i think the esp 32 s2 s3 and the classic esp 32 do it i don't know if the c3 does it but you know we use the same chip it's just module format um so if the chip supports it then uh the other module supports it if i'm using a lipo charger chip like the mcp 73 a 31 do i need a mosfet or can i just hook the load to vbet slash battery the usb lithium ion lithium poly charger board doesn't have one but the feather does um you don't have to but it's considered better if you're if you're going to power something off of it because um then you won't be constantly charging and discharging the battery if it's connected to usb like the usb will charge up the battery and also supply the current for the product it's just it's just a little nicer on the battery okay uh because right if i'm looking to do my first pcb it will just be a few breakup boards to a qt pint any tips on how to get everything connected with a solid connection would you do female headers on the board and just plug in the board's example of a breakout yeah i think uh i think buck booster headers is a great way to start because if you plug in something backward do you make a mistake you didn't lose your expensive boards okay is there any tricks to make pcbs to be able to solder castellated pads to where the components are on both sides like the qt pi esp 32 s2 um you do a cut out that's what you know there have been other modules i've seen that um have you know capacitors on the bottom it's not that common but it does happen um but whenever you have boards like that you just do a cut out around the board and then you just solder the edges okay uh question for the show about the esp 32 with external ten any tips on how to keep it on if it's your final project hot glue electrical tape etc well you shouldn't be moving it right so the way to keep it from moving is that you mechanically um attach the antenna and you mechanically attach the board and you don't have it so it can move because if it can move it's going to move so make sure that both parts don't move and then they're not going to move okay um well any more the a different music catalog be pressed and vinyl absolutely um you know obviously we're really focused on just trying to get through the ship shortage and some of those types of projects you know we just have to be razor focused i would we have everything on soundcloud and we have a ton of music that i'd absolutely love to like even do um you know like a holiday album with all our holiday songs like we just have a lot um and so that's a good news is like even if someone wanted to do that for us uh we could say okay because we do uh creative comments music uh with our with our music we so we can even team up if someone wanted to fund it once now uh we have ideas on some cool vinyl ideas um so do you take requests for circuit python libraries yes um i failed converting an old bm085.pi due to gpio and vasayo any tips we have a guide on how to write circuit python library so check it out it's very detailed but it does go through how to make an i-squared c driver um you can also open up an issue in circuit python i'll say that only about half of the drivers um that people request are written chips like the bmp085 which have been discontinued for more than five years are sort of the least likely to get done for you so you might have to do it yourself okay and this will be the last question for tonight should i try and program the esp32 s3 with arduino platform or the native expressive my project would use the esp now communication protocol over the i2s audio um idf will get you will probably have better support but our arduino is probably easier to start with um there is arduino support in 203 rc1 try it i mean it's a release candidate might work but um but i've never used either of those things to be honest on the esp32 s3 so i don't know if they work okay um a little reminder unexpected to the code please use it um we're gonna bounce a little early tonight we're still on time it's nine o'clock we did a full hour right on time um on time and on but it used to be an hour yeah um you know we just we have so much going on each week so we want to try to um entertain educate and uh we like doing this you can tell when people like doing something when they do it every single week for like a decade um that's what we do so uh we very much want to thank our team behind the scenes i think zay is running the slack chat thanks our team and also um all of the folks that are purchasing stuff all of our community members that are doing all sorts of things keeping us going contributing code doing documentation helping us out in a variety of ways and uh of course everyone out there who's just watching who likes to imagine themselves building something sometimes you have to see all the people out there doing it just like show and tell so thanks so much um we're gonna play a little bit of music and then um there's a park that opened uh pier 57 in new york and it was a little weird because um no one kind of knew about it and so uh i went there you went there this sunday or saturday and they were like that's weird there's this like park and so and so it's on top of like google and i'm not quite sure i so anyways i got in and i was by myself and i and i took a video so i'm gonna play that while i'm shutting down stuff here so um if you're ever in manhattan the pier 57 has a park and it's on a roof and you can kind of find a way in um i i'm sneaky like i'm tenacious i found a way in and i and i found a telco closet too anyways so uh here is your moment of zener thank you so much everybody this has been a native fruit production we'll see you next week here's your moment of telco yeah i could do a little bit music and well first moment of zener a little bit music and then the well no i'm just gonna do the rooftop part because it's a long video bye
