 Life New York, it's ask an engineer. Hey everybody and welcome to ask engineer. It's me lady Ada the engineer and With me is mr. Lady Ada on camera. Gonger of the gong gonger the gongs. Yeah, and Speaking of gonging we've got a soundboard that we're testing out. So hopefully we sound yeah, we're always trying to upgrade a Very interesting audio challenge with the factory going on and all the things Yeah I think we nailed it we've got Machinery we've got kids. We've got videoing. We've got tutorials. We've got coding all going on here during the day But at night It's nice and chill because it's time for us to do our show. So why don't you tell them? What's on tonight show on tonight show the code is banana plug 10% off native first all the way up to 1159 p.m. Eastern time We'll talk about our eight fruit live series of shows including show and tell which JP just did Thank you so much JP. We'll do a little bit of time travel look around a world of hackers makers artists engineers and more Chip shortage. We're gonna be doing this segment every single week probably forever this week Texas instruments From the bail bag a special father's day edition. We're gonna do some advanced Manufacturing in New York City and more some 3d printing and I've got a little special segment this week New products some top secret we answer your questions. We do that only on discord a different IT slash discord There's so many different video places. That's the only place that we can answer the questions So put your questions there join all 34,000 of us. We're there all the time hang out. It's fun all that and more and Eight of her that's right. All things you do. I'm asking an engineer. Yeah. All right So let's get started. Let's pay some bills. Don't forget banana plug. That's the code and you get free stuff Okay, we have our free be still going on 99 dollars or more. You get a free perma proto half-sized breadboard with your order 149 or more you get a free KB 2040 RP 2040 break up board that is pro micro pinout compatible has a stomach you deport lots of memory It's a great overall microcontroller board and it'll fit nicely in your subtlest breadboard and of course 199 or more you get free UPS ground shipping in the continental United States Hopefully, we'll be able to bring back circuit playground free be soon We are making them as fast as we can but we keep selling out. Which is good. All right We don't have enough and don't forget if you want to get a Raspberry Pi or other items that are in high demand make sure you two factor authenticate your account verify your account and Right now we have multiple products including There's teensy and then the Google Coral boards are Yeah, I think that's actually okay. They were they were limited for a bit, but I might I think they're fine now Raspberry Pi 3a plus is actually we had those are not Very valuable in the resell market. So a lot of projects can use it 3a plus if you don't need ethernet You know, so they come with Wi-Fi. They're very fast You don't have a lot of USB plugs. You only have one, but they're they're good They're kind of in between a pi zero and a pi 3b plus so check those out. We might even have a couple left in stock and The pi fours are going fast and furious. Don't forget. We are currently limiting one Raspberry Pi computer per customer that is all types So pick the one you want like if you really need an eight gigabyte Raspberry Pi 4 don't buy a 2 gig because you won't be able to pie an 8 gig You only get one type of Raspberry Pi computer Until we are able to release more to the public when I don't know. Yeah, but we'll let you know when that happens Okay, we do a bunch of live shows A little programming note. I think next Wednesday There won't be an ask an engineer, but there will be show until There's just everything got squeezed into one week. And so we have to do a meeting that will be running a little late I think and better to Maybe have the show a different day than try to do it a day when we know we won't be able to do it But show until was this week jp hosted it and you check it out on the Socials where all our videos are saved and stored and then next week. It's Noah and Pedro We'll be hosting. Thank you. No Pedro on Sundays. We do from the desk of Lady Eda Lady Eda What was on desk of Lady Eda this week? Oh boy? Okay? Did I mention there's a lot of chip revisions and chip shortages? So this was last week. We showed off the Luma noodles. I also showed off the LED buttons that we got so a bunch of samples. We showed off in last day. Yeah, then we do the great search Which is a pretty popular feature Lady Eda uses her powers of engineering to find the things that you're looking for on digikey.com Thank you. Did you key? What was this week's great search? Oh goodness. I have to remember what we searched for Oh oscilloscopes. Yeah, we showed folks how to get low-cost oscilloscopes that they can use You know, there are a lot of people email us and say, hey, I'm a student. I want a you know, a low budget Scope for about 400-500 bucks. So we showed a bunch of options and all the trade-offs you're going to make You know, what are you paying for basically and and what? What will you get if you're willing to pay a little bit more? So we showed a couple good options for scopes available from digikey. Don't forget they come with probes and everything A good oscilloscope will really save your butt. So even a two channel, which is what I use a lot of the time Yeah, okay. Uh on tuesdays we do jp's product pick of the week and this is this week's highlight take it away jp The neopixel 3 32 silicone bead LED strip it is a half meter. So there's 166 I believe LEDs in there and it is gorgeous. So this is individually addressable neopixel LEDs I've plugged it into a qt pi rp 2040 with a little battery bff and a little lipo battery And as you can see here You get a really nice Nearly solid display you can see as they dim there They will start to reveal the trick but at more moderate brightness levels And this is only at I think 0.35 on brightness It almost looks like a continuous neon strip except it's got this individually addressable rgb effect to it Which is really cool. That is my product pick of the week It is the neopixel 3 32 silicone bead half meter led strip And on thursdays we have jumphawks workshop and we have a couple things that we do We do circuit python parsec But I saw this neat app That I said hey jp. Maybe you can try this out So, uh, you know, you like some retro stuff and we have things like Since and adafruit's done a record before and we're always looking for like what cool new technology things can you combine? so, uh I said hey wezer has a new album with the only way you can play it Is if you spin your phone around kind of a neat thing, right? Okay, and so I gave it to jp I said hey, can you do this and of course he went above and beyond and I'll show you what he did And Where else can you see this type of entertainment for you now? So, uh, yeah pretty cool On fridays we do deep dive With tim from a guy check that out Check out all the innards of circuit python and more if you want to learn how to build amazing apps at circuit python Or just how some of the stuff works. Check it out Every single friday 2 p.m. Pacific 5 p.m Eastern okay, we're gonna do a little bit of time travel Um, this week's time travel is going to be short because uh, we like to do a little update every single week We're still waiting for parts just like everybody else. We're still doing adabox never going to stop however It's not going to happen in winter because winter happened and we're in the spring ish summer ish But we think it'll be shipping pretty soon, but we'll continue to give updates If and when we have a pretty good date, we'll probably send on emails to folks But if we send on email now the question would be like why are you sending an email because you don't know anything Right now. So we want to give you good information if we bug you in your inbox. Okay Um, and then uh speaking of ship shortages. Here we go This week's chip shortage a return, uh Returning champion so far. Um, I think Texas instruments and microchip have the two and and st And st actually all of them a lot of these companies. I can't you all you all get first last place This week. It's uh Texas instruments wood chip. Uh, can't we get this week? Okay, this chip I'll tell you actually I don't remember the part where it's a power. It's a it's a buck boost converter It's like, uh, sorry to buck. It's a boost converter. It's like the tps. Oh, right the tps 61023 This is a really sweet Three and a half amp boost converter, which can give you five volts out of your lipo battery and double a batteries And um, we use it in a bunch of boards and breakouts Um, because I really like it as a boost converter, but guess what it is unavailable. We ordered, um A couple thousand of them, you know, I think about a year ago and we haven't gotten any Uh, we would really like to get those chips that we ordered that would be sweet Okay, um, you could check out well, you know, you can check out the site Yeah, I mean, it's a really awesome chip. I do recommend it. We if you could get it you could see Dispects and more, but uh, you're probably wondering well, you know, what do we use it in? Uh, this breakout, which is unavailable right now because we don't have any tps Oh, by the way, I'm gonna go to the digikey site. Maybe I can go there. Let's me know how many in stock None zero zero 2023 2023 so lady at a if we could talk to Mr and mrs instruments who owns texas instruments How many do we need? I need a like 2000. I think 2000. Yeah, like a reel of 2000 It's not asking too much. I found a lot and uh, I'm sure you have it somewhere. Look on the couch. Maybe Hook me up. I would love to get some tps 6102 threes or lovely chips Yeah And that's this week's chip shortage Okay, this week's mail bag, uh, this is a Yeah, I forgot that we had a song But next time I'll I'll get used to it because we didn't have a song for the longest time Well, you can have the button play the song too. I could do that, but then that's another button. I gotta press um, okay, so We had father's day. I sent some emails to some of the the new dads at adafruit I've got to send some other emails. It's just been a busy week And I said, hey, like, you know, thanks for bringing life into the world and keep up the good work But I got to send a couple more because there's there's a bunch of adafruit kids happening but uh, one of the things about doing a show and Doing something like ask an engineer for a decade is there's a lot of young people That they're not so young now. They they're still young But if they were eight now they're 18 If they were 10 now, they're 20 you get the point. So here's one from a dad And uh, let me Zoom in on this Dear lady, Ada, Mr. Lady, Ada I wanted to send a word of thanks and an update to a father's day email I sent you June 25 2014. So that was eight years ago The email read just wanted to share a small part of the father's day card My daughter made for me my dad's the best because he will play robots with me at any time of the day and any day of the week Thank you for showing me how great engineering really is The dad goes on to say playing making robots e-jewelry with my daughter has made Easier and more enjoyable because the great products you make and sell your great service excellent tutorials and role modeling for young girls Thanks for all you do in supporting the open source community So eight years later here's the follow-up Since then my daughter has achieved many goals and received some well-deserved honors and part I believe you deserve credit for this your support for the open source community And dedication for bringing affordable electronics and programming circuit python to everyone not just privilege But to lower the barriers and allow me to teach my daughter and her robotics team about programming electronics or robotics In addition your dedication to support and help young women is always inspiring Thanks again from a proud and grateful dad on father's day now. There was a bunch of um other information And I said all the awards that she got. Yeah grease. She's gotten so bio med doing like Stuff to help people's hearts Inventing things. Yeah a lot of electronics a lot of combination of the arts the sciences The ee the cs and to this day. She's still using eight of fruit parts. Yeah, how heartwarming so um anyways We're gonna keep doing the show and uh, we really appreciate the folks out there that watch the show with their kids because that's kind of one of our intentions, um, we thought this could be a fun interesting show for not only uh adults But for adults to watch with kids and they could see a good example of a lady running a successful company and also being an engineer and You know having great employees that Can have a valuable interesting thing to do each day that they enjoy and make a good living at it So, um, there's not a lot of examples out there at least not one that has a weekly show So we appreciate you watching and thanks for sending that in Okay Happy father's day. It is python on hardware time Okay The big news this week is there's a new version of Micro python. So lady, what's the you know, we add the stuff that's in micro python to circuit python What's the latest? Okay, so micro python 1 1 9 and don't forget we are keeping up with micro python We are merging in their changes and so this change will come to circuit python sooner rather than later Although, I don't know exactly when maybe um when we get to eight stable in circuit python But basically the mpy format has been updated and I think it's like a little bit more compressed, which is good uses less space, but also Like you can be executed directly from like the end of the flash memory. So historically if you wanted to freeze in A library like you have to compile it into code and there would be some linking process But now you should be able to just like take the mpy and like append it to the firmware Like literally in flash and then you like you can add as many libraries you want to freeze in Which I think is a really cool and interesting idea That could be Very useful for Circuit python as well. We might you know, we might end up with some sort of like dynamic firmware generator Because a lot of people Want to save ram you can save a lot of ram by loading mpy sorry by Saving your mpy files not to the disk but to firmware Because you can execute directly from the firmware file. So All good stuff basically, you know making frozen. I mean there's a lot of bug fixes. I think renaissance post port So the microcontrollers, which is interesting for folks who love japanese automotive microcontrollers But the big changes I think are this mpy update Okay, um, you can check our collection of articles including articles about circuit python. Hector has an article on circuit python 8 It's our new version. It's alpha. It's what working on and uh last week we talked about the poster Thank you expressive for allowing us to Have uh blinka Espressifies Herself I think it's cool. Yeah, I mean it's a perfect fit um python cheat sheets projects and more um Cube is kind of neat. Uh, Todd bot has been on a roll if you haven't already One of the things I like about Todd's projects is Todd can squeeze the code Basically into a tweet or very close to and you know twitter's coming out with a notes feature Um, what's that? Well, it's it's basically like if you want more than 150 characters So you but why don't say six screenshots of your notepad? Yeah, no, they're it's they're you know I think they're making medium inside of twitter. Yeah, so anyways So I look forward to what Todd's gonna do with that but um, it's always neat to see The projects because uh Todd does open source and post up these bits of code in this cube was fun to kind of Watch and evolve over the socials Um, and then um, you can check out some of the projects using circuit python not even our hardware That's what's cool about I'm gonna have some cool badges. That's right. And uh, anyways, and you can check out things like 2040 boards 2040 boards with a circuit python pinout diagram again Um, what we like to do is build things so other people can build stuff Um, you know, it's always nice to buy some Adafruit stuff But we also like to see businesses thrive So you could check out all the different circuit python based hardware even ones that doesn't come from adafruit In the latest newsletter, we deliver it every single week. You could check that out on beautifuldaily.com And uh, we have a completely separate site don't spam Don't harvest emails. It's just for newsletters not connected to your store account at all That's how tenacious we are about protecting your privacy Do you want to play like the horn effect or something or this the twinkle effect? Um, yeah, so I have the sound board thing and I here I'll do the applause, you know, we will never spam you No idea if that works or not When we watch the uh, yeah, I think it worked watch the video. Okay. Let's do some open source hardware stuff Okay, um, we have two thousand Six hundred ninety six hundred ninety. Wow two thousand six hundred ninety guides, um That means like code repos recipes, you need it's there. What's on the big board this week? Okay this week. We've got, um, A new an update or new guide for the adafruit cutie pie esp32 s3 from liz She's been working on this guide. Um, the s3 is a little bit of a beta chip Um, but you know, we still have some arduino and circuit python support I know and Pedro made this mini smart mirror with a pie portal It's like if people make the gigantic smart mirrors, uh, maybe you want something that's desktop size And they also show how to make your own half-silvered mirrored acrylic You can buy it, but if you can't get it it is possible to DIY your own So they show you how to do that in this guide, which I thought was kind of cool and then uh, finally, uh jp wrote a massive guide on taking our neotralis, which is a diy 8 by 8 rgb led kit and um updating it with a um rp 2040 feather because uh the the m4 feather might not be as available And then using it as a midi feedback controller where You're sending data to the midi like your computer as midi commands, but also Data is coming back and being displayed. So you kind of made it work with like this I don't know the name of it, but there's some like controller that people use and he's like I want to make an open source version of it and that's what he did Okay, let's do some advanced manufacturing here in new york city All right, welcome back to w a d a that's right. We're playing all the hits The construction across the street forever All right, that's actually what it sounds like is there's a construction horns are constantly going off. Yeah, let's do some Let's do some, uh 3d printing, okay So I've got a project that I'm working on. Yeah, I'm gonna show them they were ahead Maybe I have a video first So I've a project I've been working on So, uh, the ruben is a museum here in york city and it's really cool. It's all this Himalayan art from thousands of years ago And it's beautiful. They do lots of cool activities that gong video. We showed in the beginning and they're really into sharing As in like please spread this good information this good word this this idea that maybe we can You mean they're not constantly sending people ceases ceases for being, uh Enlightened. Yeah, so they have some really nice sculptures and statues there. So, uh, we've wanted to go to some museums because Covid's happened for a while and there was a lot of challenges with going to museums It's kind of last on the list when you're just trying to survive So we've been trying to do some art and see some art and so I went and I scanned in Um a buddha looking sculpture. So, uh, I'll show it to you all right, so The idea is you could get a really beautiful scan The output from the phone app that I use is an stl or an object file Special thing add-on is it a physical add-on or no, it's just it's just a just a latest iphone And I just walked around it a bunch of times and eventually was able to capture it And uh, it worked out, but I my goal isn't to just make the A little version of that what I want to do is take that as the base for some art to do So, um, here's what the this is kind of well, this is what it's going to look like I'm doing this like pixelated Like deconstructed looking buddha Kind of you know buddha of the future perhaps and as far as like what it looks like here's here's a version It's not that version. It's just another one that's kind of like and I'll just hold it up So you can kind of see it's a it's a 3d printed one and it's a cute cuba five Yeah, it's it's kind of like if if there was a buddha inside of tron You know kind of sitting there So this is just like one example and I'm playing around with different 3d printed materials that can be illuminated in different ways And uh, this is a solid one Um, I'll just show you like, you know and kind of see Kind of see that it kind of yeah Something I can get through So, uh, I'll have some other examples later But um right now that one is printing and what's cool about that museum is they saw it And they added it to their instagram story and they retweeted it and you know Museums at this point. I think one of the cool things that they could start to do is we all have phones that can do scanning like lidar type stuff So to allow people to come in and you don't have to be able to touch it Like I wasn't there was a rope around this thing. Um, I just held my phone and I just walked around it a few times Um, that's a really neat activity Especially for young people to scan in art that they see and then when they bring it home They could do neat stuff with it and then they can remix and do all sorts of stuff Like I took this sculpture and I wanted to Um pixelize it and make it, you know, kind of look You know something like something that would be in a video game Um, so anyways, uh, that's the project and speaking of projects Here are two back to back from known Pedro. We have the cool little smart mirror and then we're going to do a speed up Hey, what's up folks in this project? We're building a mini smart mirror with Adafruit's pi portal You can 3d print and get why your own smart mirror that displays weather info When you wave your hand in front of the mirror the display turns on and then automatically shuts off after a few seconds This uses the esp 32 wi-fi module to pull weather data from the open weather maps api to display temperature weather conditions and the local time The pi portal features the at samd 51 with an esp 32 wi-fi coprocessor 8 megabytes of flash storage and some onboard sensors Our 3d printed case features a mirror like design with an adjustable viewing angle A piece of laser cut acrylic features a one-way married film so you can see the display through the reflections We think it's a pretty cool effect for projects with the display The code for this project was done in Adafruit's circuit python and uses the onboard ambient light sensor to detect your hand The code calculates what the percentage is of the maximum amount of light being read and then detects when there's a change This allows the project to work in areas with different lighting conditions We think it's a nice use of the pi portal's ambient light sensor for iot projects with displays 3d print the parts to build the snap fit case and get a piece of acrylic from a laser cutting service You can apply one-way married film to any piece of acrylic and make your own smart mirror Follow along with our learn guide to get the full step-by-step tutorial on building your own So if you're looking to make a project with an iot display definitely check out Adafruit spy portal Thanks for watching and be sure to subscribe for more projects from Adafruit Don't forget every single Wednesday. You can watch 3d hangouts with Don Pedro Tune in learn how to make all the stuff in more All right before we go on to um New products Don't uh, don't forget to use the code banana plug Because if you don't you won't save money and you'll be sad So use the code. All right. Uh, let's do some new products. Okay It's a new it's a new it's a new new new. It's a new it's a new new new new new new new new new Okay, this week. Let's kick it off with okay. There's a kind of like a half updated half new product um, so a while ago we bought a whole bunch of these um hammer header kits for raspberry pi zero that only come with Uh the mail plug header and uh, we kind of forgot to put them in the store And then we found them and we're like, oh, we should really stock these so if you have a raspberry pi zero w or 2 w or original zero and you want to Plug in a bonnet or a hat or a fat or whatever some sort of thing that uses the 2 by 20 header And you don't want to solder or you don't want to learn how to solder You can use these pimeroni hammer headers Um, and what they do is they let you um do this kind of cold weld where you Literally use a hammer or a mallet use anyone that you have already and you gently tap tap tap and pop the pins of this Um, head or through and it will make a solid connection that you then don't have to solder Um, so I'll show it on the overhead because it's kind of funky. We haven't shown these in a while Okay So you get your raspberry pi zero and it comes with like a plastic plate and then these little screws that help line things up and these hammer headers you can see there's like these little Nubs here And they're kind of like springs Like you can't press them in by hand but again, if you put this thick piece of plastic on and hammer with a mallet It will press all the way through Pop in and then you'll basically have a solid connection without needing to solder So it could be useful if you don't have a soldering iron Or you don't trust yourself with one or you don't want to give someone else one Yeah, it's a couple bucks and all you need is a mallet or hammer. Okay next up Okay, uh, this is the update to the ap 3429a which was a book converter for about five volts down to three volts We love these little buck converters once in a while. You just need you know an amp or so out Um, and you want to give it a couple double a batteries or you want to give it a lipo or give it usb And an ldo won't do the job because again, you need an amp and you're not going to get an amp out of a small ldo The only thing is the ap 3429a you'll never believe what happened phil Is basically unavailable. There's a chip shortage Hey, hey, where you where has been? How's it going? Yeah, so we ordered the chips and we don't think they're ever coming in and so I was like, you know what? Let's just revise this. I found a similar enough Chip, uh, can you go two more? This one? Yeah, it's the tlv 62569 so this is an update slash revision But I'm keeping the same product ID because It's basically just a better version of the previous chip. It's a slightly higher frequency Um, it actually has higher current output. Uh, I also doubled the copper thickness on the pcb to two ounce copper I still would only really recommend it for about like one 1.2 amp continuous But you can get uh, you know two amp peak. I think I got 1.5 amp continuous actually on this board But you know, I I won't promise it depends on the ambient temperature But if you do need like a ton of current at 3.3 volts for wi-fi for cellular This is a very fine Buck converter and as they'll break out. Well, uh, it's pin compatible with many uh To 20 to 220 size Uh, ld out. I think the ld 1117 3.3. This is pin out compatible. Okay next up Another update. Uh, this is the icarus iot board. This is the nrf 91 Oh goodness, could you go to the next thing? I keep forgetting the whole part no more It's the uh nrf 91 60 This updates a couple things one. There's now flash memory on the board second. It's updated Yeah, the flash memory is on the back The module itself got updated to like engineering change order b1 instead of b0 Um, and probably another couple other component tweaks. So this is v2 Of the icarus feather. However, it is essentially the same thing Just a couple extra updates and upgrades. It's still a feather compatible It is still a cellular module that you can program I think it uses zephyr artos to program again Not arduino or circuit python or micro python compatible All right next up and uh, you know, this is why we had the code banana banana Um, we noticed that we didn't have any banana plugs in the store I thought it would be a good idea to stock some and I thought these were kind of neat because they're not just banana plugs They're like stackable plus retractable Out was kind of cool. So these are four millimeter standard Um banana plugs, so I'll show them on the overhead because You kind of got to show the uh, yeah, I'll show the two different colors here before I go Stackability and uh Retractability, okay. So first up they're stackable. So uh each one has a slot at the end And so you're like, hey, I want more and they slide in very nicely. They're very solid They got little grippy so you can remove them. Um, what I thought was kind of neat is they have this little retracting Plastic protector so these can be like Hanging out on your bench top and like you don't have to worry about them touching Because they're protected, but then when you're ready to insert them They just sort of like, you know, just by pressing they they naturally do this like a little attraction thing And uh, you can plug them in Easily and safely. Uh, they're very high quality Cables. I really like them. Uh, so we have, you know power and ground very useful for You know, you have your bench top power supply your multimeter Um, or other test equipment that uses a four millimeter standard size banana plugs Okay, and this week we have two stars of the show this week besides you Lady Ada and our team and our customers and Everyone who makes this Adafruit thing go yeah our community. It's two boards. Look at these two. That's right. We've got two Updates. We've got the ad s zero one zero one five and the ad s one one one five uh two I squared c and long digital converters are very popular But we've stomach qtfi them because we love to add plug and play Support to all of our break up boards. We're kind of going backwards in time and now we're getting to the older boards So these are 12 and 16 bit adcs. They work over i squared c There's tons of support for them. There's um, arduino support circuit python micro python Everyday python rest whatever it's like these are kind of ancient and so they're They're well documented and well supported Um, you know the 16 bits a little bit more expensive 12 bit is going to be good enough for most uses It's actually kind of not it's not common to see i squared c adcs. Most adcs are spi and so um, you know, these are uh Very handy for when you just have to add some high quality analog inputs Or if you have a board, you know propeller chip for example or a raspberry pi that hasn't have an adc Plug it in and so now what we've updated is it comes in the stomach qt format Which means it's got these jst sh connectors You can use cables to plug and play them with our feathers with the raspberry pi So no soldering required Of course, if you want to connect to the output pins, you you may want to solder to them But at least for the entry level wiring and testing No soldering is required and you can have up to four of these. I think on one i squared c bus just by Noodling with the address pin. I think tying it To ground or tying it to scl will let you choose multiple addresses as well. So You know very easy Very reliable way of adding multiple 12 or 16 bits analog inputs And that is new products this week Okay, we're zipping right along. We have time for some questions. But first Um, don't forget go over to discord desk questions. Adafruit dot it slash discord Yeah, while we play some top secret you can get your questions in Yeah, um, we're going to show two videos back to back on our top secret and then we'll uh, do some questions. Here we go Great lady. What is this? These are some cool clicky buttons? JP our resident synth fan and drum machine collector was like, hey, you know, can you get some of those? Um switches that you see in some drum machines or or synthesizers or keyboards that have um, A kind of nice clicky tactile switch and a built-in led So I got this sample. I just soldered it up to a breadboard So when I press the button the led lights up the led is independent from the switch But I just wired it so that it turns on when I click it And I got this with black and red led gray with rally and red with red led So I think this is a good start. Well, we're coming a couple packs It's fairly inexpensive And then we'll make a package for them in eagle cad so folks can uh, giy their own 808 All right, lady. What is this? These are Neuraled knobs you can tell they're knobs because they're round and they've got a cool pointer I like that the silver one has a black paint pointer. The other colors have white paint So it has a good contrast and the sides are knurled You can see the machining effect makes them really fun to grip onto and twist on your synthesizer or drum machine And uh, these come with a set screw so you can see here the set screw I've been testing it out with a two millimeter hex wrench and the set screws nice because it means you can use D shaft right so you get a classic D shaft potentiometer or Rotary encoders and you can twist just by pressing it in and then setting the set screw or if you have a t18 or round shaft knob You can press fit it in and then also use The set screw to set it So these work with any kind of potentiometer of order encoder coming soon to the aid of food shop And that's top secret this week Okey-dokey, uh, let's just do a check in with that code. Yeah, it's still banana plug banana banana banana And uh, you don't have to sing banana songs. That's right. I like the word banana because you just keep Keep spelling it a and a well because it's stackable You start with ban and then an and then Nah, and then if you want another Nah, you can just nah again. So you banan and nan and plugs That's what we got somebody stop her for keep spelling Okay, uh, we're gonna do some questions right away ready hit me Yeah, I got some questions question. Can the ice can the I squared C carry audio sample rate wave This is actually that one of the first projects I ever worked on at my job when I had a job was um Putting a microphone over I squared C and the answer is you can do it. Uh, but only really eight kilohertz is what I determined Um, because it's you know, let's say you do, um, you know one megahertz I think we had we did 400 kilohertz Sorry, yeah 400 kilohertz clock signal, but of course, you know, it's 10 bits per bite of data Um, so you only get 40 and then like there's the bus stuff you have to do So in the end it was basically like I was able to do um eight kilohertz audio But like it's not Really designed for it Um SPI or I2S are way better at this Okay, some good feedback on the switches a little leds were on so many 80s test equipment and synths Yeah, they're like I call them 808 switches even though of course they were used in other things Here's a request. Maybe I would love to have some solderless solution to making beeps like a stomach qt breakout with a thing that Sends pwm to a built-in buzzer or something Oh, yeah, that's interesting. Yeah, I mean, um We don't have that but it would be it would be a good idea Uh, or one of those mp3 player boards with the sd card would have built in buzzer using iSquared C to trigger files I think spark fun actually has one of those by the way. So check that out. I think they have an mp3 iSquared C um Controller chip thingy Okay, um, I cut and paste one from another chat. Yeah, but please do put them in discord Any intent on making larger versions of this clip on so I see sockets. I'd really fancy so I see 24 one Someday, you know, I've not seen the clip on Sockets for anything other than so I see eight Because they're really used often for programming like flash chips and e-prom chips for FPGAs and others are like, you know bios is so I don't I'm not really seen them for so I see 24 I think we have like SMT to dip sockets, but not a clip on style. Yeah um, I think Uh, I can answer this question. Maybe yeah, I can help out with this. So, um, use eagle cad But you know, you you don't you're not religious about the tools Um, but what would it take what'll have to happen for you to switch from like eagle to chi-cat? Because it almost happened this weekend I live real time in this because like we're not tied to a particular tool set But you get used to using something and just like okay. Um, well the current cost isn't too bad I think that if if the usability of eagle um Got to the point where it's like, I can't work as quickly. I might change but You know, here's the thing. I don't believe that there's any one cad software that's really better than I think they're all equally bad Um in interfaces and they're also equally good, right? I mean, yeah But what happened this weekend because we were talking about this, um, you're like, uh-oh So the thing that frustrated me is, you know, they they do this thing where you you have to Register your re-log in every two weeks, which is on on its own quite annoying because it's a constantly like Pop it up like yeah, I'll get you all again. But the login server that they had Uh died and so like I couldn't you know authenticate Um, and so I couldn't edit parts of my board, which is like really infuriating Um, but they fixed it a couple hours later. Yeah, uh, would you be interested in making a Flexi pin adapter for the qt pie. This is a Um, you know, here's the thing about those flexi pins. You know, you have to hand solder them and so I wouldn't be able to manufacture Uh that in-house because you'd have to hand solder it. I think the idea is really cool um But i'm also not sure what you would get from that like What what do you need a flexi pin adapter to that would be better than just soldering it down? Or using headers I really like headers Okay Yeah, and you know one of the things um, you know, there's a separate Thing going on uh last week that was I was emailing some some high profile makers and just to summarize Kind of the gist of the conversation was boy, um, we're all getting separated pretty easily. We're all drawing lines and saying Us and them. Um We're not doing things together. We're shouting each at each other online and on social media, particularly twitter um I think that's happening a lot even when people talk about tools. So I I think one of the things even if You're in a good community like adafruit one of the things that we should always say is like, hey There's room for both There's room for lots of different things and sometimes it's just you're used to a tool and then you know You migrate to another one like I've changed from having to use adobe pdf creation tools to not using adobe pdf creation tools, but once in a while Um, there'll be something that can only open up on like for whatever reason adobe And I'll do that and uh, I wanted to migrate off those just for some smaller lightweight tools but I was just used to a lot of them and You know, I would never want to get in a fight over like which pdf tool is the best but people But people get you know, they they get knives come out very fast Yeah, and I think that if we're all asked to get along with Or we're telling hey, you know everyone should get along and you know be peaceful if if us as like makers and technologists Can't even be respectful and nice about what programming language we use or what tools we use Then what what hope is there for everyone else with like? Real significant issues like invading lands and stuff like that. So yeah, I just think that's anytime these things come up We can always just say like hey, you know, both tools have a lot of value Both are uh terrible in their in their own unique ways and both are good in their own unique ways But I think if we always reframe conversations like that, here's the thing. I like that there's options I like that. I'm not like Totally stuck like if eagle cad does eventually become so annoying. I don't want to use it anymore Um, I know that there's an option and that safety means I can I feel confident in Designing whatever I want because I know that chi-cad can do eagle imports Um, and that's that's how it is. I think like, you know, it's interesting. It's like I think people should Have faith they should have self-confidence in the tools they pick because sometimes I'm like Why do I use this editor and I try another editor and then I remember all the reasons why I go like my I automatically go to the tools that I use. Yeah, and you know if I ever Get a chance to write some of the maker history So we spent a lot of time lady and I talking to It was cad soft before it got bought. Yeah, and it's to them directly and we said can we get an export Feature because we really wanted to make sure people could export. It used to be a binary as as xml And they did it and it didn't hurt eagle cat at all and it allowed people to move files back and forth And then they have chi-cad import. Yeah, and so, you know If we approach that situation Dunking and shaming them. They probably wouldn't even want to talk to us. We just said, hey, there's a good way to get everyone to do more engineering and Moving files around and being able to open and save in in a format That can be shared. Yeah, that's a good idea. Okay, uh, let's see I don't know if the espo ones are going to be on adafruit But it's kind of frustrating to buy one from another electronic shop and uh, uh, okay So are we going to have the espo ones on adafruit? No, we used to and they kind of suck in my opinion and the support burden Is not worth it. Um, they're not You know, you're not only are you are you getting a board without a lot of gpio, but it's also not fccc certified and It's an esp 8266, which doesn't do tls very well and it's slow honestly everyone should be moving to the esp 32 or s3 or at or c3 or something I think the 8266 is Let it go to bed. Let it rest Let it close its eyes and go into eternal dreamless slumber. It did its job We should move on Okay, and let me just check the other chat over there Uh Yeah, it looks like a couple people are you know, they These all to him. It's great. Um, that's fine. I look. I mean all all are valid Yeah, I don't I don't really need altium. Um, I do like incad one thing if for folks who someone said they're having some problems importing uh eagle into key cad um, you know, one of the things that would be really helpful is Talking to the the product teams On both groups, uh, you know, one is an open source effort, but there's specific people that are working on these things I even like google and apple The those teams work together about specific things to make sure things work out Like they're competing heavily on some stuff, but the the engineers are interfacing with one another to make sure certain things work together So, um, if they can do it surely we can and I think they If you have experience with that like here's a specific file Um engage with them in the forums. Um, you know, I think especially if you can provide that file and say this is Isn't working they can probably track it down because it really is pure xml output. There's no reason Uh, there's no he's in any turn complete Uh cad file editor could not parse and load uh eagle files. Yeah, I'm just noticing this is a trend I'll just use this as an example. So let's say if you're trying to import something from eagle cad and uh into chi-cad doesn't work So What do you think as a maker especially if you have a following? Uh, we'll get you the best results. I'm not saying the the fastest results I'm saying the best results go on twitter and hey eagle you suck I tried to you know, you you you're changing it because now I can't import in the chi-cad or you blaming the chi-cad open source people Hey, you guys used to be great, but you're not great anymore. I'm disappointed. I'm disappointed Pity sad shame. Um, and you know make them feel bad They might they might say hey like please dms and like okay, we'll take a look at it, but like What a thankless terrible thing and then when you and then when they fix it You're like, oh, you should have done it sooner or you know There's forums and support and places where they want to get feedback and there's you know tickets that are openable And I think both entities have Forums and you could say hey, I'm a problem with importing a file Can I publish it here and can you take a look at it? So one of those things are going to work or even both, but which one feels better at the end I think it doesn't matter how you get to it and I'm just noticing it's just like I think it might be too easy to just Terrorize people online. It's very easy to Let me just see if there's anything else Oh someone said there's a key cad discord and you can go there and they'll be able to help you out So there you go. See this is why and then you know, I It's funny. This community does a great job with all this stuff I'm just noticing like the fractures and all the different communities not not in the Adafrit world But in like the other communities that are you know maker um, it's very It's very twittery And I think over the last few years everyone's been trained to um divide up And be separated easily imagine if we all got together all the things we can accomplish Um, so I think that is all the questions this week Oh, I can answer this one. Uh, any update on the rpi's the raspberry pies. No, um, unfortunately or fortunately Uh, we're navigating this the best we can so if you Need a raspberry pie and you haven't bought one you can get one in Adafrit. We release them every week Just make sure you're signed up as a authorized account with two-factor authentication and with a verified account And maybe you don't get it one week, but you'll get it a week for sure Um, please don't try to work around it and you know sell these on ebay and stuff like that Where we have countermeasures. We're doing the best we can But people have been consistently been able to get a raspberry pie What you do here is the people who say it's still not good enough. They have a cluster. They want to build Well, now's maybe not the time to build a cluster Maybe you can wait just a little bit and let some other folks have the other seven raspberry pies Okay, uh, let's uh, wrap up. Don't forget the code is banana plug I think ze is behind the scenes tonight on the show And the Adafrit Slack special. Thanks to the entire Adafrit team our entire Adafrit community here are Customers everyone who keeps this thing going for that little kid out there who's now an adult who uh was learning engineering getting inspired by Lady Aida and Probably going to go save the world because the world needs to save and that was kind of cool too. So thanks for Sending that in and thanks for doing that thing Raising a good kiddo and uh That's our that's our show tonight. That's right What's that sound effect? I don't know if I played any time Um, let me see if I can If you can hear it. It's the it's the music Yeah, brought to you by Geico Did you eat a mattress? Actually, aren't those mattress ads I don't know By Keygreens the best keto Seed oil All right, this has been Adafrit production. Uh, here's your moment is in her tpt3 of radio ads. That's right Hey everybody
