 Life in New York. It's as an engineer. Hey everybody and welcome to yet another ask the engineer It's me lady Ada the engineer with me is mr. Lady Ada on camera control We're broadcasting live from the Adafruit factory in downtown, Manhattan This is behind us is where we do all of our manufacturing and kidding and shipping and video into toiling and guiding in photography and more It's a factory. We make things. It's advanced Manufacturing but for the next hour the factory's asleep while we manufacture content about one hour of the latest and greatest news For makers engineers hackers artists and more mr. Lady Ada. What's on tonight's show on tonight show? The code is Biff May the fourth be with you the code is Biff because of Lady Ada's favorite characters from one of the Star Wars. That's right Biff They're peaceful. They're intelligent. They're sentient. They're musicians. They can't cry and Could not shed tears. So the code is Biff 10% off in the Adafruit Star all the way up to a little 59 p.m Or when I remember to turn off the code correct use the code and happy May 4th to you Okay, next up We talking about our live series shows including show and tell just did that Thank You JP and Liz time travel look around the world makers hackers artists engineers. We have everyone's Most feared and favorited segment ship shortage this week. We'll be talking about ST Got some jobs from the Adafruit jobs board jobs. Adafruit comm We are an advanced manufacturing company made New York City We'll be showing some factory footage and more some 3d printing Ion MPI what a Special I think this is gonna be one of my favorite ones already tail gloss and horse tops by New products top secret we answer your questions. We do that over on discord adafruit.it Discord join all 34,000 of us All that and more on you guessed it. That's gonna engineer All right The code is not case sensitive. I just did that so you can read it It's easy to read So, yeah, maybe the new song will be that could do that So let's kick it off by paying some bills. That's right was but lady When people put stuff in the cart to get free stuff, what do they get? That's right? $99 or more you get a free promo proto half-sized breadboard 149 or more you get a free selection one of a selection of STEM aqt boards that we have available various sensors and More and one 99 or you get free UPS ground shipping in the country continental United States It's trackable. It's insured. We'll be changing up the freebies maybe this month So if you place an order, this may be your last chance to get some of these freebies. Yeah, and We'll have different freebies. Yeah a little and just a heads up with shipping costs going up quite a bit We might need to change the tier for free shipping. So you may as well get on it now while you can You know the best time is now Don't forget to get two factor authentication on your account on a deferred So you sign up for an account verify it then do two factor authentication The reason for that is there's a lot of high-demand products and we do two factor authentication We do lots of other stuff But this is just one of the things that helps make it fair for everyone out there to get the products They know and love so thank you for doing that. Also. It's just good practice I see in the news that github will be requiring two factor authentication on all repos for developers By 2023 we're just smart. It's a good idea Okay Lady Ada, we do a live series of shows every single week. Yes To uh, that's right. I liked it. I like to stream it stream it. I like to stream it stream it So I'm full of song today. Yeah, your full song We just did show and tell Thank You Liz and JP Liz She's been doing stuff for a while, but a newer member of our team Co-hosting with JP. So we're gonna watch it. I glanced over at some of the show and tell participants. I'll watch that tonight Do check it out on any place where you watch our videos on Sunday We do desk of Lady Ada and it's in two parts Lady Ada. What was part one of desk of Lady Ada? Okay, well first up we showed some beautiful images from when we went to the Berkeley Botanical Gardens and we saw some pink Cherry blossoms that were in full bloom and then we came home and we worked on electronics. I showed off this CP-2104 Replacement chip the CH-9102. I tried it out on a feather ESP-32 worked out great. It just made sure that the baud rate was all good. I also showed off USB PD chip Cable and then the chip that's inside of it and then a breakup board that I designed that she actually recently posted up The video I think or the the images on Twitter so people can can check out that design in more detail USB PD basically lets you get multiple voltages from USB wall adapter without boost converters or buck converters or all that and you get a lot of current too So it could be really good for robotics projects. Okay, then we did the great search Lady Ada What was the great search this week? The great search this week. What was it? Oh, right. It was purple and pink LEDs because we're going to be doing a run of the pink RP 2040s as a giveaway And you mentioned that it would be nice to have a pink or purple Oh, six or three LED on it. And I was like, oh, yeah, that would be a good idea. So Yeah, so I sourced some parts on DigiKey and I also showed in general how to get LEDs in the color you want because it can be a little tricky There's a lot of different LEDs and there's different The names of the colors may not necessarily be the color you want. So how to use the nanometer Selector to find the the exact color that you're looking for Okay, then there is JPEs product pick of the week. We do this every single week I was reading an article about the future of e-commerce and they're talking about how Really advanced Innovative companies will have live video About how the products are made Live broadcast with people who make it or some of the information about it, but it'll be live. It'll be Our participatory Experience yeah like a concert but for buying stuff kind of like, you know the old days with qbc Um, yeah, so we've been doing this for a while and jp broadcasts from the product page itself Every single week the discounts automatically applied Take it away jp The feather esp 32 s2 tft This is a fantastic board. It's kind of one of the most modern Feathers that we have since it has usb c on it, which I love it has a stem of qt port on it So you can just plug a sensor or something into that just plug that right into the uh The top there on the back side you see we've got the big esp 32 s2 package on there as well as most of the rest of the charging circuit and passives and voltage regulator and so on This can plug into a breadboard this can have things plugged into it It can go into a doubler into a tripler you can solder things directly to it So you've also got mounting holes on there So you can really use this like you use any feather But the fact that you've got this great looking Sharp colorful display on there Allows you to get a lot of projects done really really easily That's my product pick of the week. It is the feather esp 32 s2 tft All right, and then on thursday's it's gp's workshop and then here's a little bit of a preview of a project gp's working on so this is Kind of the new normal that frees have been used a lot, but there's such a scarcity on parts that you You build projects with the parts that you can get and electronics that you can get to let you know When something is in stock that's harder to get So we have this thing that will sound an alarm when a raspberry pi is available to purchase on our site Kind of reminds you of the bad fun a little bit On friday's From a guy tim does deep dive filling in for scott. He'll be back soon friday's a two 2 p.m. Pacific 5 p.m. Eastern time where you Can do a literal deep dive and all the innards of circuit python and more check that out this week Time travel Let's look around in the world of makers hackers artists and engineers. I'm gonna time travel back to the beginning of the show and say Yeah, so apparently it is case sensitive right now. So all lowercase bith. I you know, I You know, there's parts of my mind that are a little dusty Because they don't have to use them. So um, yeah, it's interesting. I don't know that. I don't know either But who knows uh all lowercase definitely works lowercase though. So that's fine. I know I did that so it was more legible because I didn't want anyone to think it was blth because you know how anyways I gotta Maybe choose a different font next time. Yeah, okay So one of the things that we do every month is the iot In a a to for internet of things monthly This is I think the best iot newsletter out there because it gives you all sorts of projects that you can do It shows you hard where you can buy not even from a to for it, but if you want to that's cool This month, this is neat. This is a iot thermometer With a to fruit io whipper snapper. So this is a no-code just drag and drop really fast and you can Display this so if you want to know the temperature of a place in your home or somewhere else easily do this with no code and Free on a to fruit io. So we have that project and then this is kind of The other side of the the iot coin as they not a crypto coin So we covered this so insta on We're keeping the lights on turn the lights off So the home automation company abruptly closes and like people are working on like How to get around this which is currently happening a lot And so one of the things that you know, we made our promises like you don't have to worry about that with us It's not a venture funded Company that just does These services so folks who have this you know tied to their homes are like well the service has been down for three days The company status said all service online the company forms are down and no one's replying to users on social media So my favorite when there's a phone number and like it just rings and rings in the youtube voicemail. Yeah Home assist and open source home automation project supports the devices and there's a blog post on how to integrate these together but you know This is why we made iot to fruit io one of the reasons because we didn't want people to have hardware that was They're using it for important things or you know, like what's important like Your home it it's it's subjective But I would say that if you have your home set up So if you forget to leave the garage door open or if there's a leak in the basement and it texts you that's pretty important stuff So anyways, um, thanks for the folks who have pro accounts Um, and thanks for the folks by hardware. That's what helps. Um, but we don't have That in the future where you wake up one day and all of a sudden your stuff isn't going to work So, um, we'll keep at it. Thanks for using it fruit io Eight bucks We are going to be shipping eight bucks We moved the next box because we can't get all the parts we need first It was going to be winter then we're like, yeah, maybe spring. Uh, now it's this it's it's straight up Well, I think we had the blossoms the cherry blossoms at the beginning of spring. Yeah So it's spring like so we're still working on it still waiting to get the last remaining bits And uh, we'll keep everyone updated. Thanks for your patience. We're full So what's happening is when people drop out of eight a box You might be able to briefly sign up to get in the slots, but we have like five or six hundred people waiting So we'll see we're trying to figure out. Maybe we can expand the offerings when we have The box is ready to go, but thanks for your patience eight of bucks.com Okay, it's everyone's favorite segment. You ready? So Song in engineering stand-up meetings every morning around the world around the country this week's chip shortage lady aida is st And um, you were saying it was a little bit like mad max around here. So I have a little clip of who runs barter town who runs chip shortage town Who run barter town You know who Mask blaster I think the refresh button runs Barter town or electronic shortage town. So I mean it really is barred. I mean it's everyone's just like scrounging around for whatever they can get It's okay. We'll get the gasoline Yeah, it's a gasoline But it said it's chips that you need to fuel your projects. Uh, so it's st this week So this week we're actually doing a favor for our bffs over at micro python We were chatting with them more about that later happy nine years old everything's great We're going to talk about micro python in a big way in our python on the hardware segment Um, but we're doing a solid as they say yes, because um Micro micro python needs chips because micro python, you know, we have like 4 000 products So, you know, if we can't get one thing, it's okay. We'll get something else And we can also put a lot of money into Inventory and and ordering ahead of time But there they have one product or two products really and one is the pie board And the pie board has an stm 32 f 405 on it And they really really need some chips and this is an important project And not just to promote st but to keep the python hardware community going because Selling pie boards is how micro python supports and funds a lot of the development that they do so it's really important that they get chips Um, so our our chip shortage video this week is uh to st st Please please please Get micro python 500 to 3000 of these stm 32 f 405 rgt sixes They desperately need them. It's going to you know, they haven't been able to get them for a long time They desperately need them in order to keep Micro python going and to keep the funding going so that they can continue the development That people who buy st micro controllers use they're doing so much free development for you I think I don't even think you should charge them for the chips. I think you should send them real for free No, you know no one's asking for anything free. It's just like no, I don't know It's worth asking. Yeah, so I guess here since maybe if you can't buy chips. Can you can you get free chips? Since you're a domain expert as they say in the business day, where do you think these chips are going? Um, I think these are going into a lot of products I mean st stm chips are very popular. They're used in the industry I don't think they're necessarily going into automotive But I think they're going into a lot of industrial products It seems to be the default but you know, you hear about like, oh There's not manufacturing people aren't building as much stuff. So like where's it going? It's mysterious still to me Yeah, and they're also, you know, there there are these chips are available But the prices are like three times five times as high and and micro python can't support that They need to be able to sell the boards at a price that people will purchase and so that's why it's important that st provides the chips um and not to go on the secondary market where you can get untrustworthy Chips that could be not true. They could be um, you know, fake chips that are rebranded So they need genuine parts and they need them soon. So this is our our chip shortage request with our catchy tune Yeah, and we'll send this out to st and our contacts there and uh, maybe Um, they have some small allocation that they can help micro python with I don't I it's not even for me I don't want the chips. Yeah, I'm good They need the chips if they sent us the chips we've just sent them to that's right To uh, damien and michael python. So anyways, that's uh, this week's chip shortage Take it tune Okay, help wanted jobs at adafruit.com You can Post your job if you're a company post your skills at jobs Dot adafruit.com this week. There's two. They're pretty neat Um, basic 3d modeling required. This one could be anywhere free radical labs llc free lance And then this one is an in-person one makerspace manager at chap qua New york cool gig you would be managing a makerspace and beautiful make inspiration. It's not the person we met Maybe yeah, all right It's not time for python and This week the big news the only news well, we'll do a little bit of other news is happy birthday micro python you're nine years old Yay, you're nine years old. Yay. Look at that happy snake. So, um I'll talk about some of the things we're doing With micro python and for micro python, but first up some highlights um april 29th nine years ago was the first line of micro python written and uh, they're up to newsletter number 12 do check out micro python dot org And sign up for it and you'll get details and cool stats like this. Um, this was from the latest newsletter More commits in the last contributors in the last one year 1,210 commits that's up 817 from the previous year. There is about 13,000 commits altogether 147 contributors from 93 from the previous year They released v 1.16 17 118 Um, they gained new features you can go through all of these and then github sponsors Has grown so they they managed to get up to four thousand one hundred and fifty dollars. Um last year it was Per month last year it was 1250 Last year github sponsors didn't allow organizations to sponsor. So we Uh, I think I did a personal one on the monthly and then adafruit Uh, donated nine thousand dollars. I'm sorry eight thousand dollars because it was their eighth eighth birthday and um That's the way we did it. We did a one time there But you know, you don't get listed on it and we don't do this stuff to get listed But like there was some people are like, oh, why isn't adafruit contributing? It's like well we do we they just didn't list it So, um, we're really pleased to say Um, two things one. There's new version micro pythons. I mean one point one nine And uh, we're synced up with our releases with circuit python in the community synced up, but I didn't want to mention Um, what we're doing so for micro python now that organizations can sponsor you can check out github Dot com forward slash micro python And you can see we are now a sponsor. We're in the first spot right now I don't know how they arrange them. Maybe it's the latest or maybe it's the most because we just dropped some coin and We're the 85th sponsor That's listed on there now and they were at 84 percent to their goal and now they are at 93 percent. So You can bam get it even closer If just a few folks do it in this chat right now github.com forward slash micro python You can do it and uh, our credit card got pinged and now it's a monthly thing We're doing um, at least 500 a month to get this started. Uh, we want to get the word out and we'll be following up on our blog post Um, we'll be following up on socials and what we're going to try to do is just keep parity with like how much can we donate To micro python but also make this so it doesn't end up just being a couple of companies It's a community effort. So we all have a reason to keep this thing going Um, we buy hardware for micro python. We donate to micro python Um, but we also want to make sure it doesn't turn into just like three or four companies Doing this and circuit python is kind of on its on its own doing its own thing in its own community And like long term I expect, uh, just like the direction now There's more non circuit python boards than a different boards. So, um, we're all going to have to figure out ways to continue to help the source, but this is a direct for sure way so go to Micro pythons github and do a sponsor. You can do it. Heck by the end of the show We could get to a hundred percent. It's only three percent now. You could do it Make a big make some noise for circuit python news. I wanted to say check out circuit python show dot com Melissa's on there Yay. Yay. So the latest one. This is episode eight Melissa is on there being interviewed and more congrats paul. He's been doing a fantastic job on this and there was two projects in the circuit python world celebrating May 4th Todd bought his one he's in chat and then there's another one or two. So I was going to play both these What's this It's the world's smallest targeting computer I better not turn it off and that's python on hardware Thank you blinker Okay a reminder, uh, all lowercase. Don't do don't do the thing. I don't do that Okay, uh, already lady. We're gonna do some open source hardware news. We have two thousand six hundred and sixty seven guys Wow, I remember it was like two thousand. There was 25 I remember when it was guide number one. We're getting with two thirds of the way towards three thousand. Yeah You know numeric goals are good. Not because of a number, but because it just keeps you going It's just the fun I don't know and one of the I remember the first time was like, let's get to 500 And then I was like, let's get a thousand and then it was like, okay, cool Let's get to two thousand because now we know this thing then it's like 2600. Yeah, I used to Maybe the year or two we'll get to uh, yeah, I think so too. So what's on the big board this week? Okay, we've got uh, let me see Okay, Brent did a massive guide how to add a new board to whipper snapper So whipper snapper is our note code iot platform. It's a layer on top of adafruit.io That lets people create components and connect things together You know with various iot boards right now wi-fi is mostly what we're supporting So esp 32 boards and 8266 is and and boards with an esp 32 spi add-on like the the pi portal and stuff And the the fun house and and all those boards Or we have support for it's um, it uses arduino to run the firmware because we need something very compact and very fast And also it's not very customizable You you run the firmware once and then the website does all the customization for you But if you have a board that you would like added to whipper snapper It's actually quite easy to add support, especially if you're using one of the chipsets that were that we heavily rely on esp 32 s2 s3 classic esp 32 8266 Or sam d51 with an esp 32 spi wi-fi coprocessor Those are like the the main main nuggets that we're supporting Because of course people love esp boards So if you have a board or if you are using a board and you would love to add whipper snapper support So all the white pins show up and the image shows up correctly check out Brent's guide He'll tell you exactly how you can add support with a pull request We've had people add components. I think we had somebody even add a board. So it is possible to do so We just can't do all them. We're just so busy and we don't have all the hardware So if you have some hardware, please please submit a pr And we'd be happy to add new boards And the cool thing is once we merge the pr five minutes later. It'll show up on whipper snapper because it's dynamically Loaded from the github repo. It's it's kind of cool We're trying to learn how to make You know sites where you know, we have the runtime code, you know running on our web server But the data is coming from a github repo that people can submit prs to so we can get user generated content in But do it in a way that's of course safe and reliable next up We've got from Matt drake seven who's done some really awesome os guides before a guide on serenity os If you want to go back to the days of of your pentium 120 installing Slackware 1.5 This gives you that look this classic 90s Linux look i'm trying to remember what windows manager i ran i actually don't remember I ran quite a few of them on my uh on my linux box, but um This one has it has a nice classic feel to it. So Check it out go to windows Linuxy look what else uh lis about two product guides the dvi breakout including how to compile code for the raspberry pi pico to output that hgmi dvi to the breakout which is what we designed it for We've also got the vl 53 l4 cx. That's a new product from a couple weeks ago This sensor has arduino library. It doesn't have python or circuit python yet because ST has not written that library Another thing st could do that would be wonderful So right now it's arduino only but we have our dream tutorial It's a really nice library because it could do up to six meters Time of flight ranging which is like really far Like I can't throw that far so Check that that guide. We've also got the mega rgb led matrix cube You've been wanting an rgb led matrix cube all of you well. We finally did it. We've documented it We have 3d printed files everything you need to make uh either the most compact cube or the easiest to build cube There's two builds same code runs with the raspberry pi 4. Yeah, you're going to have to find one But I'm sure you can scrounge one around And then we've got a lot of awesome demos. We'll show the video shortly. It's a great video And then carter wrote um an oft requested guide. We have this eight channel iSquad c Expander where it's like if you want to connect eight of the same iSquad c address devices together You can use the this tc 8014 I don't remember the exact part number To do so But you want a basic guide of like okay sometimes you can change the address How do you do that in arduino and circuit python? If using this expander, how do you do that and make sure that you select The right port. There's a couple just little like details to watch out for we see people make the same mistakes So carter wrote this guide that we can point people to because it's it's pretty common now that people are like I want to connect You know five of these time of flight sensors together, but I can't change the address. How do I How do I do that in arduino or circuit python? It's possible, but you just have to be very careful okay, um Let's do some factory footage Advanced factory footage in new york city for us right now unless uh this disney building Uh wasn't being made here. So that's that's our version of main new york city. Yeah Big old disney building cross street Watch it build okay 3d printing Okay, this is the tutorial the guide This would have a lot of been folks been waiting for so it's not the finale of moon night. It's better Yeah, so we've had a couple like Long-term ideas for aid of fruit like when will we know we're at the state of the art for some stuff? Like what wouldn't will it be easy? Well more people will be able to use this where Folks who never thought they could be an engineer Um younger folks older folks a diverse group of people doing engineering and sharing and some of it is like well like There's a project that we want to do and it just was not possible and It was too expensive or too hard and the software wasn't there whatever and this led cube is one of them Another one is to be able to wear a movie. So we I want to make a jacket that is just plays blade runner the whole movie We're getting there. Yeah, we're getting closer and closer and this is a decade ago. We started talking about this We're like, yeah, one day we'll be there the leds get smaller. There's a certain It's not Moore's law, but it's like the density of leds on a flexible surface So we have ideas, but this is like another little glimpse And uh, you know, you got to just keep scratching you make your little you're your little dent in the electronic universe And uh, this will be a project. I think that'll be super easy for folks This is something people want and we just went through and we just did all the hard parts. We documented it We did the modeling We did the plastic design and we did like it's all magnetic. It's all done for you So if you want to make an led cube, you always want to do this You have no excuse. We have everything ready projects where you make it and it's an heirloom that sits and you know It's more than just like an electronic project. It's actually like something beautiful. So anyways, here we go Hey, what's up folks in this project? We're building an rgb matrix cube with 25,000 colorful leds powered by a raspberry pi This is a six-sided cube that features 64 by 64 high density rgb led matrices It's driven by a raspberry pi 4 with an adafruit matrix bonnet We have some beautiful demos like this flowing pixel sand demo which uses an accelerometer for mesmerizing motion effect The grains of sand trickle down and move across all six panels making this physics toy unlike anything else To drive all six panels. We're using a raspberry pi 4 computer with an adafruit rgb matrix bonnet This little add-on board makes connecting rgb panels with hub 75 easy to plug and play We made two different sizes of the cube and both are documented on the adafruit learning system The bigger cube features 2.5 millimeter pitch panels with built-in curb cut frames for an easier build The smaller cube uses two millimeter pitch panels and has fully 3d printed frames It's tougher to construct, but it's the smallest pitch possible Both cubes feature neomedinium magnets making the panels easily snap fit together To power the cube we're using a 5 volt 3 amp usb battery bank It's compact and small enough to fit inside the cube alongside the data and power cables This version of conways game of life was specifically written for the cube to allow the cells to travel across all of the panels For static displays We have an image viewer demo that you can use to better understand the cube's typology Once you've gotten them in the right format jpeg and png images can be displayed You can experiment with all sorts of texture maps no matter how bizarre The globe demo takes images like the earth and projects it onto the cube while spinning and animating You can try this out with other planets like jupiter the moon or even the death star There's an option to wrap the texture vertically so the polar caps are mapped to the corners Be sure to check out the guide for a full step-by-step tutorial on building your own matrix cube Thanks for watching and be sure to subscribe for more projects from adafruit Okay, and so that was the video from the beginning That we showed this is a jp head and one of the reasons I thought this was funny is when um the co of twitter at the time jack left or whatever version of How things work now? Um started block and their bout page has all of the people who work there with like You know, it's just photoshopped on a block, but i'm just like well Like this would be really neat to do for real too. So, um, I don't know. Maybe they'll see this and uh They could store their wallet and Okay, uh, and then the other thing we've got is a speedup. Yes, and it's dragon-based Don't forget every Wednesday at 11 a.m. You can learn how to make all this stuff and more with the longest running live 3d Show with no major 3d hangouts All right, the code is this but lowercase all lowercase. Don't don't Do anything that looks like this just all lowercase just the i is lowercase b should be lowercase t And uh, that's a code for 9 10 off in the infrastructure all the way up to 11 59 p.m. Eastern time lady adah Sign on pi time. That's right This week's ion mpi is tailglas Tailglas. Yes This is a really cool irish company that makes a lot of antennas. In fact, you've probably used their antennas I have before they make ones for gps and wi-fi and cellular and all sorts of stuff, but this week in particular we are highlighting um, their multi-band SMT antennas these are um ceramic antennas that you can pick in place to come on a tape and reel And they have a massive wide band Um, uh, this one in particular the pa 760 Wide band is 600 to 6000 megahertz Which covers a wide number of bands is shown here basically 4g 5g 3g and 2g Including wi-fi as well. I mean basically kind of anything really between 600 and 6000 And you need this because and i was wondering like why do you need so many bands? Well, um, I'm used to cellular stuff You know when I was first designing cellular stuff with the sim 800 This is a gsm gprs module So gsm otherwise known as 2g Covered the whole world with basically quad band although honestly it's really dual band because you know 850 and 900 megahertz and 1800 and 1900 megahertz are pretty much The same frequencies and they're also multiples of two So, you know getting an antenna that could cover those two bands basically 900 and 1900 megahertz Was not too bad. Um, you know, we have one in the store. That's that's very inexpensive That covers both and has I think uh 2 dbi gain Um, and that was wonderful and great except that 2g is no longer used in north america and a lot of parts of europe Instead we have you know, i'm skipping ahead to lte Uh, which you know, you're probably familiar with because your phone is a lte phone Well, guess what there is like, you know, basically 100 bands available For all of the different Speeds and bandwidths and ranges that people are expected to use 100 bands. It's wireless palooza. I know so, you know, a lot of this is You know, I don't go through all of these some of these of course more popular than others But countries have different bands available and also Depending on a category of lte, you know, there's there's categories Zero category 1m up to a category I think four or five The higher the category number the usually the higher the frequency and the higher the bandwidth is for you know transmitting video audio You know high speed internet Whereas the lower categories category zero category one Those are used for machine to machine stuff. You know with the low cost 2g network used to do When you just wanted to send temperature data over cellular or you wanted to you know, have a credit card processing machine that just Sent authorizations over cellular. You don't have to have a very good quality high speed connection because it's only connecting very rarely It connects to the cell, you know, the cell network Verifies the credit card and then disconnects. So for that you might want a less expensive lower power Cellular module that uses the lte network and you might want something that has better range because You know, it's it's okay if your fancy cell phone maybe doesn't work in You know a basement eatery But we've been to restaurants where when you go downstairs, there's no cell phone service but you know if you if you have a alarm system or a fire you know detection system or a credit card processing system that uses cellular Well, it needs to work everywhere. And so those categories zero and category one bands might use something as low as 900 megahertz 600 megahertz to get really good penetration through Walls and through wood and through, you know, even if something concrete But again, you know, it's lower frequency. You're not going to be able to carry as much data But you will be able to carry it a lot farther. Also good for rural areas So this is an example also of uh, you know, I looked at another sim com module. It's an lte module that That i've you know, used before and it's lte, but also has Gsm fallback and that's pretty common too. So even if you're not necessarily if you're expecting us to use lte You know in some countries there might be gsm as a fallback capability, especially in in some rural areas that still have gsm or 2g That's another reason why you might want to have multiple bands So this is the antenna or a very similar version of this antenna As an example on a dev board by tau glass. And so this is actually kind of like an iot All-in-one edge Sensor platform thingy And you can see that, you know having an smt antenna is quite nice because first off, it's not that large Compared to I mean it's big, but it's not that large compared to the cellular module Um, and it allows you to have like a weatherproof design or an enclosed design without like this like jengly Antenna sticking off of it This could be you know, so what I thought was interesting is, you know, if you have an uh a cellular module That can do cat zero cat 1m up to you know, and as well as it looks like maybe they have wi-fi or bluetooth as well This could be handy for um some projects some of the projects that they had as an example was if you have A horse farm, so let's say you have a horse farm and you're in You know the irish countryside And you want to track the location of your horses because their horses they run they run very fast They run very far But maybe you want to kind of know where they are sort of on your property So you have a gps module you need to get that gps tracking data back to you But again, you're in a rural area So you might want to use a cat 1m or you might want to use gsm to get the best range But then also when they're closer to the farmhouse You might switch over to wi-fi where you don't have to pay For roaming charges and that's where you know a multi-band antenna could also come in handy If you could switch you have an antenna switch and you switch between cellular and wi-fi Or maybe you also have laura-wan and you have a horse mesh network All sorts of ideas and sometimes you have to keep track of the temperature of the horses their heart rate There's a lot of things you have to keep track of yes, so they do have they actually did a horse monitor project Which I think is a great example of I'm just gonna iot your wild horses. Yes, so so that edge where I think this is the same board as we showed before And this was used for a project called horse pal With with a company that I think makes horse blankets I mean there's nothing there's really nothing quite More romantic than than having horses in the irish countryside and you're you're riding them and caring for them and then monitoring them with LTE cat 1m modules, so yeah these modules You know they would slip into the horse blanket and you could use them to Locate your horses and also just make sure that they're all doing okay, and they're moving fine And here is that's right, sir. I love my horse and I keep track of my horse. This is the co-CEO of towel glass And I think the blue thing he's holding is is the module I think you know one has the battery on one side and the other side is the Edge module you see it's encased in silicone To keep it waterproof because horses, you know, they are they can roll around in the mud So you have to make something that is not going to Get dirty or you know, you can't have like an sma connector ward which could come loose Which is why it's handy to have your antenna embedded inside So if you are excited for an smt mount antenna, well you're in luck because there's quite a few Models that half of them are currently in stock at digikey fell about digikey Including the pa 760 that's right. She's also called the warrior x wide band at the time of this screenshot in 2576 the band of of frequencies is as wide as a horse's butt. Yeah, and uh, there's a little horse video But um, you know, I have to be careful what some of these sales videos because they use Music, so we're just gonna we're just gonna show you the video. So this is the you know, do do do This is the music. This is the logo. Okay, and then and then there was just like drum horse where that's the name of it Yeah, and it wasn't there. There was no horse sounds. It was just music. So I decided yeah, you're not losing out on anything with with horses Okay, well there you go. So tall glass. Thank you so much for um Inspire ins you know, I always go to the videos of the company and Sometimes I just like to pick the coolest one not necessarily like Exactly the video about the antenna, but there was an antenna In that horse blanket. So it's it counts Okay, and that's high on mpi All right, a little reminder all lowercase-beth that work Apparently that's apparently other ways did not ten percent. Yeah. Um, because the email support if uh, if I messed up Okay, um, let's do this for new products. That's right Okay, first, uh, bleeding at uh, okay, we've got a Flappy cable. This is a 34 pin 2 by 17 idc cable Uh, it's rainbowy. It's festive. Um, we're gonna use this to connect our floppy drives together um, it's got a keyed and strain relief edge on both sides Um, you don't have to use it for floppy drives You can use it for anything that has a 2 by 17 Point 1 inch header, but um, you know chances are Uh, you've got something You want to connect from one board to the other This cable do the job. Next up we have a, um, Battery monitor for a lipo or lithium ion batteries. So anything that's 3.7 Volt slash 4.2 volts And uh, it's pretty easy to use. It's a kind of simplistic design Um It's got, you know, basically a resistor divider on the back actually go to the two images forward Yeah, so it's got a it's made a little microtroller and it's got like a resistive divider and um, it does an analog You know comparison and then it lights up Um the different segments. So if you go back one Yeah, so you can see um It lights up, you know, the outside basically is like, you know, you have at least 25 percent and then The rest of them light up for each, uh, 25 20 percent. So if you go to The overhead Although my battery is now being finicky Okay, so, um Hold on, let me just auto focus Okay, uh, so this battery, you know, I've had it sitting here for a bit. Um, it's a very basic thing Obviously it's going to drain your battery. So you don't leave it in all the time Um, it doesn't have um, you know, a exact voltage doesn't have exact percentage, but I think Um, there, you know, it's inexpensive and you just have it in your toolkit You just want to really quickly check a battery if it's dead or not This will give you a rough idea of, um, your, uh, battery Percentage range of charge, you know, if it's charged up or if you have to put it in the charger Okay Next up we've got some more beautiful artisanal leds. That's right. We've got from deluxe delight. We've been getting Various colors and designs. So, uh, this week we've got these red spikes. I think they're super punk and funky But they could also be used if you have like a little garden gnome. We want a red hat That's a good idea It goes up all sorts of interesting ideas. Um, you could do so it's a red led embedded in a, uh, translucent uh, clear body You just, uh, provide it with some voltage and it lights up. We also have a blue crystal We had the yellow crystal a couple weeks ago Uh, fallen up with the blue crystal. Um, using for model making using it for art projects I don't know. These are just very cool leds and I'll show them off on the overhead as well So this is I'm gonna be alright. Yeah, so this is the, uh, blue leds. So it's brightest in the middle, but the whole thing is, um, lit up and then, um Ditto here, you know, the bottom is where the led is and then the whole, um The whole spike kind of lights up Nice and diffused. So this is Two different new shapes and we've also got, you know, I think we got some more white skulls That came in and some other, um, shapes and colors that we restocked Okay, and then the star of the show tonight besides you lady aida our team our customers community Our staff is it's out of this world. It's yes. Well, this space theme today. So this is, um, A solder together sts kit, uh, where you can make your very own desktop, um Discovery, uh, this is modeled after the real nasa discovery which had like like a hundred missions or something ridiculous Very very popular space shuttle It comes as a pcb that you break apart and you have to do a little bit of soldering There's three, you know flame effect leds. So that's a kind of a cool like it looks like, you know thruster Flames coming out the back And you have the stand and then you have the two pieces that slot together and then on the bottom There's a coin battery and a switch so you can turn it off when you don't want to have it glow But um, it's a really adorable first off if you love Space shuttles then of course this is awesome. Um, but more importantly, uh, if you want to learn how to solder This is a great little kit and it's um very easy to put together Yep And uh, spacey so, um, beautiful silk screen and you can see it's got like a slide together design It's got the flame effects and then on the bottom is the coin cell Which uh, you can pick up at any hardware store or we also sell them and then turn it off when you're done And uh, that's new products That's right Okay, uh go post your questions up in discord adafruit.it Slash discord join all 34 thousand of us, but that's where we're gonna answer questions We're gonna go to them while you're typing your questions up. Let's do some top secret I'm gonna play two short videos lady data and then you're going to talk about the two designs that uh We're posting up. That's a secret. Yes. So here we go. Take it away past us Early data. What is this? This is a ESP 32 feather v2 and I've swapped out the cp2102 and or cp2102 104 with a wch chip called the ch 9102 you can see the wch logo there and it's a pin compatible version Of a usb to york converter uses different drivers. It's not like a complete direct clone. Um, it's your lead new drivers but it's pin compatible and um, I was just testing it with Uploading code to um the csp board at high speed. So I want to make sure it works at Um, the high speed we use which is uh, 921 kilobot. Um, this is more info about this chip It's kind of new but this is great because I'm having some difficulty getting enough cp2102 So this means I can keep the hardware in stock. We're gonna make it through this chip shortage Together, so let's see this update soon in the shop Early data. What is this? This is a very interesting usb cable It's got usb c on one end and then a 2.1 2.5 millimeter dc barrel jack on the other And if you look it says here 12 volts 5 amp It actually has a usb pd chip inside here molded in So that when this is plugged into an adapter like this one and you can see here That this one can provide a various different voltages like 9 12 15 20, which is perfect because those are the cables I have And then if I plug that into here Hold on And then I plug the cable in So then on this end I can measure in A nice clean 12 so a little more than 12 volts I actually might have heard that's on the scope and I'm I put on my load meter and I got three amps out of it Easily so because that's the max I could get on my load meter Um, so this is a pretty cool cable. We'll have these in various voltages 9 12 15 20 in the Adafruit store soon All right, lady. What's this? This is a breakout based on the same chip in that usb pd cable That um, I think will allow you to close some jumpers to select how much current and voltage you'd like to request from a usb Cpd power supply and so we'll try that out. It could be a handy little board And then uh, you know, I got these samples of ultra wideband Um indoor positioning modules and um, they would make for a great little feather wing because You need a processor and they use spi and they need a bunch of components. So I put together a quick feather wing design That's not a secret. Okay. We're gonna go right into questions. Okay, so First up This one I get to do a cut and paste Someone wants to know where's that cool video of that horse? Everyone loves horses. Yeah, so the horse is electronics Yeah, it's this video That we showed earlier But instead of it just being um Us doing the narration you could listen to the drums. Yeah, I also posted the digi key part The social media for the company And the video of the horse Okay, yeah Ready it's gonna be the most popular video on the internet tonight next Uh folks like the shuttle that's cool. Yeah, it's good for young folks, too We also wanted a kit that um, you know, there's like fighter jets and stuff like that We wanted something that like kind of everyone is like, hey, you know, space shuttles space shuttles like you know, space shuttles Okay, next up question. Adafruit. Can you share which esp 32 x the whole family has been most popular? I think we can I actually am not to be honest I don't know because the s3 we just put out with your guess Or which one do you think I think I think the classic is the most But um, I think the s3 could be quite popular because it has the dual core and a lot of sram on it But it's very new. So, you know, I don't know. All right. Um The esp 32 vroom 3 2 d is now n r And d is there a newer version that's first for both wi-fi and bluetooth with a Comparable number of iopins. Um, I mean it's probably just a revision. So it's probably like the 32 e or something But check check out the expressive Part selector because they have all the revisions and they can tell you what the latest version is Okay, no question Just a hug report shout out to the folks who've been maintaining the Adafruit CAD parts repo over the year has been doing a lot of fusion 360 Tinkering on 3d projects this week and have ready to use models for Adafruit gear has been great for sharing fit And getting good feel for how things will look when the project done. Thank you. Yeah Appreciate it. It's known Pedro did a lot. Yeah and also contributors. All right Question while on the topic of esp 32 thoughts on sma connector module We have all sorts of sma adapters in the shop. So, um Check out what we've got. We've got, you know, a ufl sma antennas estimated sma adapters, you know position changers all that good stuff Uh, someone just said they noticed that uh, the featured products in our featured section are out of stock. Yep That's right. That's they're very popular It's a chip shortage, but we have other things every day every way Do you think we should not have stuff out of stock in the featured section or because they come in now people sign up And then they do come in out of stock. Yeah And that's how we do business You figure out what's the best thing you can do and sometimes you got to Pick something that's not ideal, but it's the best you can do at the time. That's right. All right I'm gonna just look around for a couple more questions and I think we got through all of them There was there was a question earlier in the evening But it wasn't in discord Uh, oh Here it is. Um, well, this is it's a similar one. So close enough The panels, uh, do they have any type of sensor? Could you make it like a digital rubik's cube for the, uh Cubes could you like do you could absolutely add touchscreens add touch sensors if you'd like And you could have it be touch sensitive That's cool Um folks had some accelerometer ideas with that Um, yep, someone's gonna someone's gonna make the lad cube and hang it from a chain. Yeah, for sure That's gonna happen. Okay, uh Next up any updates on esp 32 s 3 circuit python ble hd. Nope. Okay Do I think? That's gonna be Yeah, well, I'll glance over if there's any other questions Most of the time we're right on time. We're right on time. Um, don't forget the code is all over case biff biff Because of the best musicians the cantina. Yeah I think we can all If you know if we're gonna meet aliens a peaceful intelligent sentient species Hairless doomed head doomed dome teds Black glassy eyes you could stare into lacked eyelids Couldn't shed tears they found work as musicians scientists and engineers What a good gig. Yeah, that's me. I sing and I engineer. That's right So, um, that's our show special thanks to zay who's behind the scenes doing stuff in slack special thanks to everyone in the chats all of our team our customers our community Um, everyone who's just uh keeping it better keeping it together the best you can we're trying to hope You've enjoyed this time and we know you have lots of choices where you spend your time and with who and your money We very much appreciate it. Don't forget the code is biff. It'll be on until 11 59 Here is, uh, the last little thing I like to do So it's been a different production. Here is your moment of zener night everybody
