 Life from New York, it's Ask an engineer. Hey everybody and welcome to ask engineer. It's me Lady Aida the engineer with me Mr. Lady Aida we're broadcasting live from the downtown Aida food headquarters where we do all of our Testing and shipping and manufacturing and kidding and coding and videoing and more I've got a jam-packed show for you tonight Sit back grab some iced tea or some lemonade and let us delight you also mix the two together You can also mix the two together You can also put them in an LED cube and shake it up What's on tonight's show? Mr. Lady Aida tonight show the code of succulent 10% off in the Adafruit store all the way up to 1159 p.m. Eastern time at tonight get 10% off in the Adafruit store and free Stuff as you check out of the store. We do a bunch of live shows We'll be talking about those including the show and tell what just happened right this moment You could also watch it after this show if you want on any other social media channels Time travel look around world makers hackers artists and engineers What's going on? From the mailbag will read your letters to us help wanted some jobs from the Adafruit jobs or jobs.adafruit.com post up your skills or if you're a company hire cool people Gonna do some advanced manufacturing and main New York City factory footage We got some great 3d printing related videos We do an Ion MPI this week is from Ozram brought to you by Digikey lady It'll talk about that and more we got some new products. We got top secret. She's really cool We're gonna answer your questions. We do that over on discord Please please please hang out on discord at different IT slash discord That's where we answer all questions because we got video streaming going everywhere when you have the chat in one spot Discord join all 35,000 of us over there We're answering questions 24-7 hanging out with you and sharing projects and more all of that on tonight's show Ask an engineer Okay, so the code is succulent it'll all make sense later Succulents it'll all make sense later Let's talk about the free stuff they get so in addition to the 10% off code when you order stuff Free things we has freebies and I know it's a more you get a free half-size from a proto PCB great for making your solderless projects solderful 1.49 or more you get a free KB 2040. This is a pro micro shaped pink PCB with an RP 2040 micro controller Stem a QT cast-related pads usb-c Memory and more a great starter dev board with the popular raspberry pi RP 2040 199 or more we get free UPS ground shipping in the console in the United States and Back by popular demand and also because we actually could make them we have circuit playground expresses at 299 or more our favorite dev board with all the goodies built in it's wonderful to use with Arduino Circuit Python code org CS discoveries or make code and don't forget especially if you're trying to buy a raspberry pi There is still the limit of one per customer and also it's for verified accounts that have two-factor authentication turned on That's just a good idea Anyways, if y'all read the news lots of security things going on. It's a good idea if a site supports it do Two-factor authentication and on top of that best suggestion if you have a choice of using your phone as a mess text message or Something like a hard key as they say in the biz or something like a authenticator choose An authenticator or a hard key. Those are often better options, but we do we support you to us like we start everything Yeah, check it out. Okay I'm gonna talk about some important stuff right away before we jump into the live show thing so This weekend Saturday our forums will be getting upgraded maintenance new version of everything We've been working on this for a while. So what does that mean? Well, if you were I Think the expectation for a lot of folks is like, oh, it's a weekend I mean if I'm in the customer support forums, you know, they they they're there Monday through Friday But you know, we are usually there on weekends So this will be one of the rare times when if you when you go to the forums and it says under maintenance And you can't post anything. Obviously, that's what's going on. So feel free to hang out in discord. You can Email us, but we'll probably say just check the forums Yeah, and a bit so It's very rare. I think we have like, you know an uptime of like nearly all Yeah, no all nine nine point nine nine all yeah But this is one of the times where we really want to get a lot of new features in and we want to have a lot of things that make it easier for our moderators and our staff and our engineering support team and our customer support team and Lady Aida and myself and an entire team of people that makes it Probably the best most responsive place to get help with your data for products in the world So that is coming up Live series of shows we just did show and tell and on the show and tell thank you Liz and Melissa who hosted and co-hosted Magenta strong heart was there But you have to stop by head of design partnerships at design lab, which is supply frame and talked about Learn about the 2022 hackaday super conference. So you can watch that One of the cool things I think and this is just I'm gonna make this about me for a second Hackaday is still going strong I started that site a million years ago and I've nothing to do with it now and now there's these events and all sorts of things So this is super con six. They're doing their call for proposals August by August 18th, and so if you're thinking about doing a talk there if you're thinking about joining Going conferences are back Please check out hackaday.com and look at all of the blog post stuff that they have all the event listing Venue information and then when you can submit your proposal if you want to do a talk there So thank you Magenta for stopping by and we will continue to use show and tell as a place where all Entities who are doing conferences events and more in this maker electronic engineering world. So one of the things that We had going on last week, which was kind of neat on the show and tell was Adam Savage came by myth busters fame and tested comm and Jen Shackner and Sophie came along and Kevin did you key is sponsoring the comic con out there the silicon and comic con and The neat thing about all this is this is kind of one of the first big maker events in California again, so some way to make her fair, but now it's bolted on to a almost literally bolted on to a Comic book convention comic convention. Yeah, culture. Yeah Everything so I mean comic cons are barely about comics anymore, and they are but yeah, well the origins. Yeah of it So if you go to silicon s j.com You can use the code Adafruit and that gets you like 15% off. We have nothing to do with the sales We make no commission. We are just helping get the word out using our platform. So We had all this on our site and we're doing a Big promotion on Friday to help them out But it's called the silicon 2022 Savage maker first and you can read all about it They had these cool like playing card like baseball card things So it's Adam. That's Jen and then Sophie's there Jay was on our show until tonight. So anyways, it's all kind of cool, and I really hope that folks go and Next up we did desk of Lady Aida, and I think I forgot to tilt the little graphic on the side So you'll have to look at look at what happens. You remember what you what you did for this one I don't know if I looked it either. Okay, so the first one is we I showed off connecting to the ESP 32 over Wi-Fi workflow and then the next thing we did is I showed off the a new breakout that I wrote a circuit python library for the max 17 Yeah, 048 which is a replacement for the Technically end of line, but not completely discontinued LC 709 203 So two things. I mean, well, I basically did it I Spent a little bit of time this weekend on the Wi-Fi workflow just testing it out So I just showed hey, if you have no joint go, it's a great. We're gonna show that as mark our top secret tonight Okay, and then we did a desk of Lady Aida Great search great search segment and this one was this one was where I basically showed the process that I went through the previous two weeks where the LC 709 203 was you know end of line and it's time to find a replacement and I found the Max 17 048 and a couple other options, but basically I explained why I picked the max 17 048. Yeah Usually when I put the highlight videos in I have us off to the side But I was down to the wire tonight. That's literally down to the wire We do things with wires. We love wires. Yeah and wireless. All right. J.P.'s product pick of the week this week Here's to this week's highlight It is the motorized slide Potentiometer But you can see the cool thing is we can play around and then let go and get back to our Preset position there. Thanks to the the motorized fader. We can also go to other presets. So if I click my encoder I can go to a Different preset hit another one of these are just four positions that I've pre-programmed. I've Set up my rotary encoder as a direct control there. So you can see as I turn the Rotary encoder I'm changing the position of the fader. I'm also using that as a stored position So now if I hit this four times, it'll come back to this position. I have four saves. So one two three Four I'm back to that new position. It is the motorized slide potentiometer Okay, and don't forget J.P.'s workshop is this Thursday tomorrow coming up and then I Believe Tim is back this Friday doing deep dive Scott was special guest returning to Scott's This is this is a a comic-con origin story. Yeah, it's the the original Yeah Scott was back last week. It's kind of like when you have, you know, like Batman played by like You know the first deep dive origins. Yeah issue number one classic condition So that's coming up on Friday. Yeah Watch that at 2 p.m. Time travel. Let's look around in the world of makers hackers artists engineers We got a bunch of stuff going on some reminders of news a little bit of everything First up we'll talk about this in the Python on hardware section, but a reminder Next week Friday 819 is circuit Python day. It is a day-long celebration We also have a lot of stuff going on on our website right now because believe it or not It's back to school time. Sorry kids. Oh my goodness. So we're doing this like school house Rockwick, and aren't we? It's like that. Cool. Yeah, and This is a little bit of a follow-up. So a while ago On our show. I showed this cover and this was from 1979 Elector and I had visited an exhibit in New York Earlier this year by Kelly Heaton and it was circuit garden and then I saw this cover and I think maybe Kelly Posted it up and I was like it would be great to see Elector like take your stuff and put on the cover and This is kind of a theme now Can you go back to the previous one? Yeah, like check out the K and Elector is like a diode symbol. It's so cool It's so cool. Yeah, and so they This is the summer edition and What a cool thing and I was like wow wouldn't it be neat to see? You know a little bit of a look back but look forward at the same time So Kelly is on the Kelly's work is on the cover of Elector magazine. Congratulations Kelly Heaton and to do check out our work check out our you know post on our site about Kelly's work and That's kind of cool Anyways, I thought that was neat. Okay Next up eight a box So we're still in the middle of a chip shortage. We thought we would be shipping a winner one Oh, no, no, no, we thought we'd be shipping a spring one. Oh, no, no, no We thought we'd be doing a summer one. Maybe maybe maybe we'll see if we get it out in the fall unknown Things are starting to improve for the amount Chips that I couldn't get before I could get it's getting better. It's getting better, but it's been a long road So thanks for your patience everyone. I know sometimes for the folks who don't like Check the website or like look at any of our shows or any social media things They are like, oh what happened? But a lot of people know what's been going on in the world and the country So they've been patient. There are some products that have been out of stock in the shop And today we actually got some shipping notices for other makers that are able to get parts So it's it's I don't know. It could be The Sun's coming out a little bit. I don't know something's happening after a long storm. Yeah, something is happening That is for sure. All right, next up. We have some aid food. I own news It fruit IO has a very cool. No code. I Don't know what you want to call this service system. It's it's no code IOT. It's a way to connect Yeah, I don't like it So we have some updates the whipper snapper components got a new look. Yeah, check that on the right there It's like you've got icons. Yeah, we've got custom text So the IO team made a new visual update for the components and sensors connected to whipper snapper The components for devices are less generic. Not only do they look better, but it adds function So if you look at the IO components now, they have icons and labels explaining what the component does So this one is a flat vibration switch Anyone can submit any component or part by just modifying some JSON code So if you want to add your own favorite part, you can and then we've also updated the look of how like ITC sensors Yes, we had it no longer just says raw. It now says percent for humidity. Yeah degree C for temperature or you know Millimeters for distance like there's SI units that are displayed to make it easier to Yes, this is a big deal and big UX update and the other thing that I wanted to mention is We made circuit Python org and you know the download area. That's where all the boards are So anyone can add their boards. There's more nonator fruit boards thanator fruit boards Why would we do that? It's because we want to be get build a big community together And it's okay if there is other boards That's how this whole thing can grow and that's why it's very popular. We're doing the same thing with IO and whipper snapper and These are all videos that are gonna be online forever Yes, and you know, it is deleted. Yeah, there's a there's a debate is information ever lost and Depending on that are lost. Well, it may be Evaporation for black holes. There's a debate about that But anyways, most people in the science biz agree that information sticks around for a long time So that's why I'm comfortable saying this IO whipper snapper Circuit Python.org. So we will always allow all boards will always allow people to put what their components on there We're never gonna say you can only use Adafruit products on all these things or you can only have Access if you own Adafruit hardware. Yeah I can't take that back. We we have out there. No submitting sensors and boards We're gonna we're trying to make it easier like we're learning how to do that But one of the goals is also we want to make sure that people can add boards without needing a lot of experience either Yeah modding adjacent file. Yeah modding adjacent files is getting close That's about so, you know, I scored C and not I scored I scored C components are tough because of course you Did driver but none I scored C components just that act like a switch word analog input You can now add Dynamically and once we merge the PR it'll appear on whipper like two minutes later. So yeah It's good for us because it allows us to be transparent. It allows people to find bugs, you know fixes It allows, you know, we were hoping at some point in the future people can add, you know custom components for their own Installation, I think it's all interesting. We're we're trying to build this out Not just a transparent way that people can interface with but also in a way that makes it easier for us to develop Yeah, like we don't want to have everything hard-coded either that kind of sex Yeah, so that's our big vision and strategy with all the stuff I think one of the things when you look at technology a lot of companies they want to divide things up and isolate and Have a forced, you know smaller thing because they're like well We can never let someone else use our thing who doesn't buy our thing We decided that the whole goal of maybe not only these sites that we've developed like whippersnapper and IO or The circuit python.org not only is it a is it a place for people to get information? But it's a place for people to come together So if we just said oh only ate a fruit stuff that would be a smaller number of people that would come together Then if you said everyone's welcome So anyways, please check it out And if you're thinking about adding some components to whippersnapper you can put anything you want there That's right. And thank you to the people who have added boards You know boards are easy to add as long as it's one of the supported families like ESP 32 or 8266 or whatever Components are good. I squared C components are still challenging because you both have to write the I squared C driver side and The components side, but we're working on it. We're trying to figure out ways to make it easier. Yeah, okay No back All right this week's mail bag Thank you for the excellent customer service and a wide array of products I'm building a healthier cooler cloud chamber for physics and geology demonstrations The goal is to cool a chamber down to negative 40 degrees Celsius using the a cooler fingers crossed. That's cool That's cold literally All right, so jobs bored We do this jobs worst thing jobs at Adafruit.com. It's where people post jobs And this is another service that we do lady and I check out each one to make sure it's not weird or sketchy or scammy They're not this is the jobs that were on the jobs board this week build fun electronics and document them a remote position That's really fun. Oh my god GPS tracker with pager personal project. You could check that out All right Python on hardware this week in our top secret section later I'm gonna show one of the stories. So you don't have to worry about that now This is the is be 32 programming in circuit Python web workflow, which is super cool So we'll go over that circuit Python day is what I want to talk about and Yeah so We have panels that we're doing Q&A We have Paul who does the circuit Python show will be there. We have a chat with cat knee Jeff and Dan They'll be going over all the things that they've been up to. This is a third year in a row Special guests for circuit Python day show and tell will be Liz. She'll be doing a show and tell Scott will be talking about all the changes in circuit Python 8. So we have a full calendar I'm chat with cat knee on Friday where we have some other odds and ends that we're gonna we're gonna do so it'll be fun exciting day we're giving away those tablets the hack tablets and Here's, you know another thing that's going on just great timing blues wireless is doing a webinar reimagining IOT deployments with circuit Python Check that out and then we have a just it kind of an unending Newsletter of just projects it goes on and on and this is all Python on hardware and this is all stuff that you can make and build and share and the projects are from keyboards to things in space to E-ing to absolutely everything. It's a happening right now Paul who does the circuit Python show is interviewing Joshua Lowe who does Ed you blocks. Yeah, and so please check that out as well the circuit Python show is like pretty amazing check out the show list and there's probably something that You didn't know or you didn't hear you heard about or it's like, oh, this is cool a block editor for circuit Python or you know other Python projects that you want to make and You know, you're at the beginning of of this really big community of people doing Python on hardware and Good work, Paul. It's one of my weekend podcasts that I like to listen to when I'm walking around You can sign up for the newsletter. We deliver to you every single week a different daily and Oh, you know what Paul's in the chat if there was a guest or anyone that you want to see on the Python on hardware You know, it'd be cool. Well, if we can keep this Python on hardware thing. Maybe we can Get Guido the the Creator of Python because I would love to hear like hey like look at this thing you started and now like it's a full-blown Like operating system on a little tiny microcontroller that you can get for like five bucks. That's incredible. Yeah, it's amazing So anyways, that's cool. Maybe we'll we'll put our we'll make some suggestions And maybe we'll reach out to a Guido at some point. That'd be kind of cool Anyway, so I guess I'd like to see Open source hardware we're open source hardware company of two thousand seven hundred and ten guides Lady Aida We have a bunch of updated guides. These are just the two guides. We released this week Yeah, these are the new guides from known Pedro and Liz is this really adorable two-way You know telegraph it uses analog feedback servo and capacitive touch So basically this is you know, I this is basically like every media lab project that I saw the media lab But of course back then 20 years ago It was very hard now you can actually do it as a weekend project with a 3d printer and a cutie pie and a little bit of copper tape But basically, you know would have been a thesis You know these two devices can be anywhere in the world that communicate through a different IO with Wi-Fi as a back-end And if you want to send little messages to somebody on your desk You grab it and you you move the telegraph and it gets transmitted wirelessly and the one on the other side of the world follows along and so Actually, you know crafted this, you know Phil and I were looking at some old media lab projects But I just thought it would be a you know It's just an adorable way for two people to Communicate with each other and and keep in touch if you want to send messages And it makes a cute little whirr sound as as it moves Well, the neat thing too is you can be anywhere in the world like let's say if you know You're traveling away from your your family or loved one or friend or partner and you give them one and you have one You know, you're like, oh, what are you doing now? And you just move it to heart Oh, what are you doing now? Oh like I'm gonna eat and you can just kind of like eat at the same time And you know, it's kind of it's cute. This is I just think it yeah I mean it's I know you can text but like there's something adorable about the tactile System and no Pedro and Liz came up with a great project. So Liz also did a guide on the mc-5603 You know one of the things about texting Is Because our phones aren't fun anymore. Yeah, it's kind of like computers It's like you do your taxes on it. You like you get bad news on it. You do work on it It's not like a fun device anymore. Yeah, so like now super computer phones are like that too It's like so right before the show like there's all these like text messages scams going on So it's like log into your Amazon account. It was suspended watch out. You know your TD bank account It's like okay, you just get phones that are like your car insurance Yeah Yeah, we don't even own a car and that's like your car is getting towed quick click here and log in like okay So anyways, let's do some factory footage And uh this week's factory footage is a little different. Um, it's just a view outside um are one of our windows and some birds because um We normally have some footage of the disney building being built across but they're raising Disney Plus prices So I I thought maybe we just take a break from that because I have to I have to decide if it's worth it as a Well, you know, we don't really watch Disney Plus, but we have it. Yeah, so I'm thinking maybe maybe we won't Well, I just if we're not going to use it maybe these birds. Yeah Okay 3d printing All right, so first up we're gonna show the project that we were talking about earlier the you know connected Disconnected connected pairs. Yeah, and then we'll do a speed up. So we'll see you on the other side You can build an iot telegraph with analog feedback servos and circuit python Inspired by ship engine telegraphs. This uses analog feedback servos to make a simple yet modern two-way communication system Use it to keep in touch with a friend by letting them know when you want to grab a bite to eat Go on a walk or just get together for a cup of coffee These emojis represent the activities you're interested in in the 3d printed handle lets you select the one you'd like to do A piece of copper tape is used to detect when it's being held and released thanks to the magic of capacitive touch The analog feedback servo keeps track of the handle's position and sends it over wi-fi using adafruit i o as the broker Powered by the adafruit qt pi esp 32 s2 this small yet powerful dev board is packed with features perfect for iot projects It features the esp 32 s2 wi-fi chip with 13 gpio pens capacitive touch and native usb for running circuit python or arduino The circuit python code runs on two different dev boards and uses adafruit i o for sending data between the two The analog feedback servos are calibrated and record the position of the servo when it detects the handle has been touched When touch input is released the position of the servo is sent to a feed Each telegraph has one feed for publishing and a second feed for listening To build your own be sure to check out the guide on learn dot adafruit.com We hope this inspires you to check out circuit python and adafruit i o for your next iot project And hang out every single wednesday With no impadro for 3d hangouts where you can learn how to make all this stuff And more i gotta say some of these projects that we're doing now This is like welcome to the Imagineering power hour where it's like this is stuff that would be so hard to do a few years ago Now it's like oh, here's a little bit of python and like, you know, you don't have to do any 3d I remember this is like this is so cool Capacitive touch was so hard Doing it two things connected to wi-fi was so hard now with like circuit python esp 32 adafruit i o And all the built-in libraries. It's like not saying this wasn't hard No impadro and lis did a really great job on this but it actually was possible It's possible to build this project in like a week It is this is so hard to do This is a great idea You kids have it so good now Okay, I don't really like I went to a talk by at some like it's like summer con a or something And a friend of mine did a talk about sock, you know about socket tcpip socket like buffer overflow or something And he said hey who in the audience has written a tcpip stack and I was like Yeah, the cirrus like 8810. I like wrote a tcpip I wrote like a foam scratch tcpip stack and like I'm so glad you don't do that anymore. Like I'm glad I'm glad I did it But I'm also really glad that nobody ever has to do that ever show me. We're on the network diagram and hurt you Everywhere Let's uh Let's let's heal the pain with some succulents. Yeah, and uh, it's time for some eye on npi Yeah Okay, this week it is a um osram lady adah What is the eye on npi product brought to you by adafruit indigiquity this week this actually this is an eye This is an eye for a optical sensor from as am am s osram This week new this funky little chip. I actually kind of like this drawing that they made this is the as 73 43 a New chip from it's a spectral sensor. It's got 14 channels spectral sensing 12 Color and then one clear and one flicker detection. So it's a kind of 12 channels of color will show all the different spectral colors and this is a a great sensor that is really nifty because Normally when you have color sensors It's something like this that you know the tcs 34 7 25 a well known and well loved color sensor You know this sensor has rgb And clear so you know a really old breakout we've had and you see in the middle there There's four diodes. There's the clear diode red green blue and then they go into an adc You know there's some filtering done and then you can read the data over i squared c And this is fine. You know as long as you're basically trying to Look at something and and mimic what your eye would seek is our eyes If as long as everyone watching this is human Have this kind of spectral response. You have red green and blue cones And then depending on how you know wavelength hit that Hit your eye You know a wavelength that is yellow, you know, it's it's technically the wavelength is you know You know 6 10 nanometers What happens is that it triggers your your red green and blue cones and then your your eyeball perceives it as yellow And as long as you're like detecting the the basic color of things like Oh, is it orange? You know, is this a skittle that's green or blue like you're trying to mimic what a human sees You can use an rgb color sensor because you're just trying to look at what a human looks at um And that's totally fine But if you're actually trying to find the more complicated spectral response of something Like this is a lamp and you can see that there's there's wavelength bands. It looks overall white. Maybe or maybe a little bit yellowish Um, but the actual You know each nanometer wavelength that is emitted isn't just red green blue. It's like there's a continuum Now if you have a very expensive, uh Spectrometer you can make a graph like this. Maybe you don't need something that is completely continuous Maybe you're happy enough with something that can detect A couple separate bands and then you can kind of figure out, you know, what what bands are emitted by You know doing some math math analysis, uh, you know based on You know seven to twelve points So the previous version of the sensor, which we you know, the reason I was Excited to see this is we've stopped the as 73 41. Uh, we designed this two years ago and this sensor, uh, you can see here in in the middle has, um It this is I think it was called a Uh 11 channel, but really it's eight different colors and then like clear Flicker and then I think like clear minus near IR or something Um, so it's basically eight eight ish channels of of color spectral sensing Again way more than the three that you normally get red green blue That would have like orange and would have like near IR and have something more violet Uh, so this are This is the center wavelengths of each channel. So it goes from, uh, 415 nanometers up to 910 and then clear and flicker detection again are separate Um, and then uh, this is the new 73 43. So you can see it goes lower down to 405 And it you know, there's there's way more bands in the middle there. So, um, you get 12 total bands of, uh Peak wavelength detection It just gets you closer to that, you know continue. It's you can see you're getting pretty close to, uh, continuous readings. There's like all the way from You know ultraviolet down at 350 Peaks at spectro responsive red around, you know, 680 and then Near IR you get a little bit over there on the right. Uh, it looks like 100 to 900. So, you know, it's it's much better. It's not of course, it's not fully continuous, but for the price It's really great. I mean, you don't have to have a full Spectrometer setup with like a diffusion grading. This actually can, uh, read the individual Diodes that are doped to respond to each frequency So you get something that's better than just what humans can see. You actually are getting a more scientifically realistic view of the light that's being emitted Um, and then this is what the sensory looks like which I just thought was such a cool image I wanted to include it so you can see Uh, you know, there's a couple There's multiple diodes for each color. So like f1 has two Um diode elements clear has the four corners and the IR has Over the side, I guess, you know, they lay this out in a way so they don't interfere with each other, of course That's the sensor, right? And then this is how you wire it up. So likely as 73 41, uh, the 43, um, has the spectral sensors in the middle What's nice is that, you know, you don't even need a lens if you don't want Um, and then you can connect to it. Uh, you should power it from 1.8 volts You'll need some level shifting perhaps But you just have i squared c and interrupt The gpao is handy. I think I remember quickly the like the as 73 41 You can use that to control an external illumination led like we found that kind of a wide band white led you can use that If you're detecting a flat surface rather than light, uh, you bounce your You know neutral light off of it and you can detect The color that way so a nice update to the 73 41 looks like it's pin compatible You you know the code's not going to be completely the same because of course there's more spectral elements However, you can probably start with our arduino c or python slash circuit python code to get you started with this chip Okay, and available on digikey and when we say available, we actually mean it. Wow. It's in stock And you get 366 of them and it's not too expensive. I mean, it's like six bucks So it was very cheap for what you're getting And they have a cool video so we're going to play that and we'll see on the other side This video is for the as 73 41, but it's very similar and I thought it was in theme So just be aware that 73 43 has more Elements, but the video talks about you know only 11. This one has 14 I've worked for ams for 10 years and I managed the field applications engineering team for the americas I would definitely want to be able to sense and enjoy the beauty of color So I would choose to be the ams as 74 31 11 channel spectral sensor The human eye is amazing. I have Lenses in my eyes and I can sense all these wonderful colors Well the as 73 41 spectral sensor also allows the sensing of eight channels of Visible light, but even beyond the visible light which my eyes can see The 73 41 does two things that my eyes can't even do It can sense flickering like in light sources And also the as 73 41 is able to sense Near infrared, which I definitely can't see I think if I were the as 73 41 spectral sensor I would be able to enjoy all these colors both seen and unseen at the beach here today Okay, ladies before we go over to new products. Let's let everyone know the code. Don't forget succulents to code and when you place an order You get a bunch of free things. You'll see it As you add things to your cart So you get a twofer as they say Or three for if you get more than one. Yeah. All right. Let's do this All right, so what do we got first? Okay, first up from our favorite British maker Simon monk Uh, we end Duncan Amos. I guess also friend probably our second favorite. Yeah person comes is awesome electronics notebook Um, we have a couple electronics just books. We've stocked, but I really like the design of this one It's got some cool things going for it one spiral bound. How can you not love that? So you can both tear out pages And also lay it flat. I always love a lay flat binding. It's got the nice plastic Binding as well so it doesn't get bent. Yes, it's got the you know extra reference pages that you Have expected and seen in Many books. So in the back You know, they've got the resist the color resistor chart common op-amp circuits ASCII tables micro python and circuit python GPIO zero and Arduino like starting guides, but what I really love is So on each page you get both grid, which you know, it's great. So it's a nice light grid But on the other page you get this Half size breadboard layout that's kind of faint So you can draw your circuits over it and then make notes about Your circuit diagrams, which I thought was like a funky trick. You still get, you know, three sides of the page that are You know, you get the left sorry The the back of the page is is still gridded, but And of course you can write over the the breadboard. It's it's kind of lightly Printed, but I thought for You know, I think I kind of imagine that side monkey. He's written a lot of books Um With circuit diagrams and he's probably like, hey, I want a notebook that I can use to diagram My schematics on a, you know, you can draw like a pico or aduino or trinket Um and write out the leds. It's like it's like paper fritzing. So I have a bunch of notebooks and I've been like, you know what if it if they were spiral bound I would use them and then I just sit there because I'm like, oh, they don't lay flat And I can't do what I want to do with it. Yeah And so I have like a pile of notebooks. So this is like one of the first ones that I've seen Um And I don't know why people some folks stopped doing spiral. I think just the way, you know Everything was a mole. Was it moleskin? I actually I apologize. I didn't realize this this is dedicated to duncan He was he was an assistant, but he he actually passed away. Okay. Well, then it means more then I didn't know that there this is actually there's like this beautiful epitaph in the beginning Oh, well, I didn't read it before we that's okay What a great way to uh have a tribute to someone that obviously simon cared about this is really good So, you know, this is the thing about supporting maker companies There's more to it and this is like, you know, every little special touch That goes along with these things and like this is dedicated to someone who probably had a big impact on On simons. Well, one of the things I'll say is everything that simon designs is like really he really he's very thoughtful Yeah, um, all right. Well, I'm gonna take a look at that right after the show. Check this out Okay, lady. What's next next app? Uh, you saw this from a group of makers that love to build stuff with bricks Uh, sometimes called lego or lego compatible bricks. This is a builder mat Um, specifically designed for those folks remember you asked about yeah, I was like we should stock this And here it is. We added another photo afterwards that was yeah, well, it's okay. I'll show you on the overhead But basically it's it's one to one Yeah, you put the bricks on there. Hold on hit the bricks hit the bricks. So hold on. Let me actually grab the bag of bricks All right. Well, I'll show this uh Yeah So if you have a bag of bricks like this um so What's neat is um, especially if you're like you don't want to count And do sizing um This is sized exactly for um, doing so this is like you're you do a lot of lego stuff. Yeah, yeah And it's all like apparently like it's got like the one third width like it's everything is Sorry, it's this way. So it's like Uh double block and then yeah, this is the height so you can like Do your math and your layout um, and you can decide how big you want it to be like brick size You don't have to like count it out And there's also an area for um angled the angled pieces. Yeah, and then this is um Life life size. Yeah little human figuring. Yeah, I saw this and I was like this would be kind of neat and now that It's in person. It's even more impressive. Yeah, it's actually very nicely made mat too. It's like really thick And it lays nice and flat. Okay, cool Great for brick builders. Next up, you know the code was succulent. So uh, this is why um, Mark DeVanc who's been doing an amazing job with these artistic beautiful lovely Succulent Yeah, I you know The the best artistic leds in the world. I mean, this is it. There's nothing else like it Yeah, these are cool. I'd actually like the succulents because the color actually looks like the color of succulents So, um, we had green and now we have a yellowish green Okay, and the stars show tonight besides you Lady Aida our team at Adafruit our community Our customers is We have updated the quad or sorry 14 segment quad alphanumeric displays to have stem and qt connectors on the back Um, so it's the same size and shape and pin out as before Um, but uh now you can plug and play it much easier Um, for now, you still have to solder the um digits onto the display but you can get them in Uh, let's see click on the first one. It's blue Red and then we got some even better photos. Uh, so the next one I think is green Yeah, yellow. So, uh, yeah, no, they they've got the contrast going well. So, um, yellow orange is yellow white and Green so red yellow white blue green Um, so each one of them it's again the same code as before but now plug and play and I'll show that Yeah I'm gonna show these one of the things, um We get asked once in a while is like Does Adafruit do like CGI stuff because no one ever shows any electronics with, you know, the lights working on it Yeah, and so we're like, no we actually did this it's it's hard And um, we also do live demos on our shows As well because we really like to show these things just to show you it really is easy We can run a company run a show and somehow manage to also do live demos. Yes, and they work So yeah, this is great because it's it's it's so it is really bright I mean the contrast is very good in person, but of course it's tough. They look really but like it looks nice It's very nice. So now it's plug and play. So I've got like this, you know This stemmy qt board and I just have a connector going to it So it's easy to plug and play and then you can of course chain More displays if you like for this one. I just soldered in Swiss pins so we could like quickly change out the colors because I want to do this demo So we've got bright green and then You can also get let's see. I'll just swap out one You can get red Get the right way around live demo, there you go Yeah, lit it up though What you did what I saw it. I know but uh, you know, I didn't insert these flat I was all like we do live demos check I know I know but the problem with live demos is sometimes I yeah I'll edit in post Dude, do you look up perfect? Is it? Everything's fine. Everything's fine. Everything's okay I think it's going on Everything's safe. There you go. Okay. I fit it in Hi, everything's fine. Um So it's nice about the 14 segments. Of course, you can see if you're doing Letters you can have like lower case and uppercase letters And so our libraries have um for circuit python arduino have a font that you can use that will um display it nicely Otherwise, um, it's plug-and-play the one update that I did do is um, there is now Instead of two power pins, there's a vio and a v high pin. So the vio pin is the same as a systemic ut pin Which means like in this case, it's running off of uh, three volts, which is we just plenty plenty bright But um, okay, I'm going to do a dangerous live demo because I didn't try this ahead of time Yeah, okay. I like I like you learn nothing But it so it's running at three volt power and three volt logic, but then I can connect this to You Usb power Whoa, and then it gets even brighter. So now I'm powering just the leds I can power just the leds blowing up the camera. It's so bright Okay, uh, yeah, so at five volts power and then Three volt five volt three volt five. We can see it's a little bit different. Yeah, it's a little bit brighter um, so handy and then I touched on thing But it's handy if you are if you because one of the issues people had is oh, they wanted to use three volt logic for the driver chip, but they wanted the leds to be Driven from five volts to get like a brighter look, especially for the The green and blue and white which have a forward voltage of about 3.4 volts. So Updated it's one of our stomach beautification Projects we're trying to go through every product and qt fi and so you can see we're going back in time This is one of our older products. Um, but now it's plug-and-play. Yep. It's new products Alrighty, don't forget the code is succulent We're going to do some top secret and then load up any questions. Yeah, we were Getting to some real time in the chat earlier in the show Adford it slash discord. That's we're going to do some questions, but let's first do some top secret This week's top secret is a video We filmed and it has the new esp 32 Workflow that's right. I'm well, uh, scott added support for the ordoid go Which I was like, well, this is really nice because it has like Everything built in and it's a huge plug, you know, everything's ready. So I was like, you know, I'm lazy And I want to go with the easiest thing so even though the feather has been supported for a while I wanted to wait till we had something with a screen on it So I could quickly see and debug the output. Okay. I'm going to play the video. Go for it. What was this? Okay, so we have merged web workflow on esp 32 for adafruit circuit python Thanks to scott and dan for doing the review and what that means is now when we have devices like this ojoid go Which is this really cool esp 32 Based gaming platform if I turn this on And wait for it to boot and it's connecting To the internet you'll see at the top bar It's going to connect to wi-fi and it gets an ip address 10 dot 0 dot 1 dot 113 And if I go to my browser and I go to 10 dot 0 dot 1 dot 1 dot 13 you'll see That it connects to um, this is served by the device itself And then I can click on the serial terminal and um I can actually type in stuff into here and then it shows up On the terminal here. So this is uh a complete echo print hello And then you can see it here. So I can control and communicate with the esp 32 over wi-fi using a chrome browser Okay, and that's top secret and you can uh check out the blog post that we have on this As well. Okay. All right. So we're going to do some questions Um, I guess I'm loaded up Right now Rocket is it possible to use circuit python with hardware that requires millisecond or microsecond polling accuracy example feather m0 with rf 95 feather Ola display debouncing the push buttons etc um, well in general embedded Languages that are interpreted like python micropython circuit python judon. Definitely don't do Um Microsecond, I mean even microtrollers don't really do microsecond accuracy It's quite hard. Um, but for stuff like debouncing a button We have the built-in key matrix debouncing circuit that runs every 10 milliseconds in the background and does the debouncing for you Um, so I would use like the key matrix capability. Likewise with the OLED display I will draw the OLED for you like take advantage of the stuff that circuit python Does do in the background and then if you do need like special timing stuff um pulse IO can do some specific timing like for um sending or receiving pulses and if you really need like You know very precision timing waveform generation Um, something of the rp 2040 which can generate p. I o customized pulses is is the way to go But just like you know, you wouldn't you're like I need Microsecond precision why because to drive neopixels. No, you don't we have a neopixel library It takes care of the timing for you do not try to do that in well python code Okay, I can answer this one because uh, this is something I actually think about if somewhere to dumpster dive at adafruit Would they find any good loot? No, so because like we're old hackers, um, one of the things that's important to us is uh, we want to you know Hack the planet, but there has to be a planet to hack So a lot of things that we do at adafruit are Uh either recycled recyclable. So they're separated out anything that has any type of information on it like Any of our employee forms if we have to do any type of paperwork and a lot of things are electric electronic base now, but we um Our team likes shredding paper if it's anything that's also we we work a lot of boards like anything Yeah, if you you know, we on the electronic side. Yeah on the launch on the electronic side We we will send it to e-waste, but honestly, we don't really we we really fix and try to get as good yield as possible We try not to uh Dumpster anything like you're probably gonna get mostly Coffee grounds. Yeah, there is the compost stuff. So the loot would be probably Maybe some lunch that's what I need. Yeah, uh next up Question for someone says worn out black t-shirts. Uh, you know what actually the worn out t-shirts a lot of folks may cut off Yeah, um question for the show You sell different gpio expanders here's a list of them What expander would you choose if you wanted to connect to an external board and manipulate a button press? For example a short to ground Example the spy cam that has a wire you short ground with a microcontroller Honestly, any of them will connect to ground even the uh pcf 85 74 So I would pick the one that's in stock. Okay What's the smallest new pixel or dot star to three pixel that you think is somewhat easy to hand solder with solder paste? No pnp and uh mark and chat says The uh hand soldered five Millimeter side ones honestly the easiest to solder are the reverse mount ones The three three point five the three millimeter reverse mount because they have those big ass pads so those are quite easy to solder of course you have to have a cut out but um, they were their joy because there's You know, you you don't have to worry about heating the led element that the pads stick out quite a bit Yeah, and this isn't a question, but I want to thank um bruce mr Certainly in the chat he had some really good tips on people for people Um on what not to do when you're called and it's like oh, it's your mortgage your uh, it's del calling you It's microsoft saying or you know You have to pay a fee or the irs saying like this is really good And I think that's one of the things like we do this with our team for um, just like security Education and training But if we all talk about this stuff like it's okay to like oh, you know the scammers aren't going to get me But if if you're good enough with all this tech stuff Always make sure even if you know you're around other techie people just a good reminder because like this could happen to anyone Um, like I said just right before the show I got this like your amazon account suspended like you know log in to fix it and so thank you Bruce for giving folks those tips because I think that's really important that we all just keep that this is just part of It's just part of being in the uh the the the the internet um Actually, I need an ice to see processor with some horsepower tried to sam d 21 can get it to work What do you recommend the tc 3.2 is my go to right now? Uh, if you need something that can act as a peripheral, I I'm pretty sure the rp 2040 has an i-square t peripheral example Um in arduino and in pio We don't have a support for it in circuit python because I know people have asked for it But I do know that i'm pretty sure in arduino and um, maybe micro python and maybe The definitely the rp 2040 sdk That'll be the cheapest because you can just grab a pico and wire up any You know any i-square t pens and try out the peripheral library Okay, and with that is our Sure for this week. Thank you everybody. It is very much appreciated Like you're spending your time with us succulent. It was succulent So you learned um, don't forget that's the code. I can't believe we've never used that word before as the code I always have to check because if you use the code, you know, I can't use again people have used Other codes to buy succulents because we've had these the other colors before Um, but now that that code is over. Uh, well, not quite Got a couple more hours. So uh user to loser to everybody Um, thank you. Uh, jesse may behind the scenes a to free team all the folks in the chat the community the moderators The helpers and more all of the customers everyone out there everyone who was on the show until tonight. Don't forget to check out Hackaday super gone Coming up and also silk on Coming up All these things are happening in the world of making it's a good time to show and share Your projects with people not only on like show and tell but at events It's happening again. So we'll see everybody next week. This has been an a to fruit production Here is your moan of zener. See y'all Bye everybody
