 Hello and welcome to another episode of show and tell this is a special episode where I'm your guest today normally it's fill in the more sometimes it's no in Pedro but today I got to take the reins so I'm excited to see your projects and talk to you about what you've been up to if you're interested in coming on show and tell head on over to the aid of fruit discord it's a to fruit dot i t slash discord you can go to the live broadcast chat channel and in there you'll see a link for our steam yard or stream yard I've got steam on the brain is that steam deck stream yard where you can join in and we'll take a few minutes to take a look at everyone's projects have a little chat and we'll be done in time for ask an engineer which is happening right after this this week so thanks everyone and first off we're gonna bring on from did you key our good friend Kevin Hey JP how you doing I'm well thanks how are you I'm good so what do a couple really exciting things well the first thing is we had our first successful tests of the our new warehouse so people will begin getting their parts even faster and with a lot more technology built into it it's it's an amazing facility I'm still working on getting the approvals to do show and tell from deep inside one of these days and you just send a GoPro through the thing for us I would love to you know how many people have said that 360 camera on the belt and the 20 minute life of your order or something you want to do things it's amazing the other thing that's exciting which I'm gonna have to chat with no way and Pedro a little bit and learn a little more about 3d printing but we are creating a low spot that is going to be a digi key addition so little brighter so instead of all the lime green it's going to be red so we're pretty excited about that we just got everything finalized this week and we should be taking inventory very soon and selling these awesome walls about 3d printers oh that's really cool so those are going to be in that sizes what they do they do multiple sizes they do multiple sizes but the red digi key addition is going to be this the sidekick size 747 it's 300 by 300 it's pretty nice that's great oh it's a nice size bed yeah wow we're excited about it is that something that is going to be for sale online soon did you see did you have a digi website very soon for we're getting close so I mean I just thought I'd give kind of a sneak peek to the the viewers on show and tell that you know that's coming and the only restriction is that it prints red filament exclusively exclusively red filament which is exactly why I have white on it right now that's really cool that's exciting congratulations on that yeah well it's a great company to work with so we're we're looking forward to it is that one that integrates octa print or other so this one I have with the Raspberry Pi shortage you know it's hard to get pies but I'm running octa print on the new Pi 0W2 oh wow so it's a really small form factor and I was actually able to fit all of the hardware inside of the see if I can point to it inside of the controller box so it you know it's great and then there's I have a camera set up and I you know I have a how-to guide on how to get all that set up on on maker.io but yeah we're excited about it we're trying to do more maker things more 3d printing that's really huge that's so exciting to see did you keep doing something like this that's that's so very targeted at that maker type of community with 3d printer yeah and even you know education all the schools I was talking to our local school and they're getting a bunch of printers so it it's out there so that's great congratulations more guys you know in Pedro I mean they're the they're the geniuses behind it very cool all right well thank you so much for that thanks for that announcement and we'll check in soon to to maybe see you see that in action sounds good well thank you very much thanks take care all right let's see next up speaking of noe and Pedro and 3d printing and lol's bots what a coincidence two of our printers just died on us oh coming out of the garage kicking it out in there so yeah there's two available spots no kidding oh well that's gotta get filled I'll continue cleaning it off and getting my red filament ready and I don't know if you have noticed like the screenshot for our show that there's a lol's bot in there we're already ready to go really good fit I mean it was made to be yeah so this week switch cameras there we go yeah so PT sound or found these really cool Nike shoes that came out that have like these heels on the sides I let you attach three printed like clips to them so of course his request was some circuit playgrounds attached to that with some like little rocket boosters the Nikes come with their own sort of like printed not printed these are like injection molded it keeps saying that but it's like a TPU and of course it like barely fits on that there's no like mounts for anything so of course we recreated it so you can go ahead and get all of the STL files so if you want to edit it and attach any other sort of you know any of the Adafruit electronics on there so some you know air quality sensing or something or just do fun like you know all the kids have you know they run around you know this every kid shoe has the light up LED so of course I don't have any for adults why would they so here's a way to make your own so yeah I'll completely modular they were using like these like what is it these these screws that like were rusted so I was like dude come on what cheap out on that not use like these cool PC thumb screws you can go ahead and edit you know have those go on there like that so everything attaches with the screws and then you can of course print your own modified version of them because you know everybody has different shoe sizes you you can have the files you can edit it to your flip size so yeah and then the code for this super simple and make code so it's using like the g-force when you step it does a little animation and I don't definitely can't hear the pu pu kind of I heard a pu pu yeah and because it's yeah you you know doing all the make code stuff so cool you can go in there added like the iteration for this so fast so of course you have like yeah when you fall you have like a little animation and I don't think anybody will hear that but if you just happen to fall while you're doing your cool skateboard trick be alerted there and yeah just simple super simple little project you can do for any of these 3d printable heels for your Nike shoes and of course PT wants to highlight it so give them encouragement you know for other companies to go ahead and start adding these because you know it's super cool platform to be able to attach whatever 3d printed accessory you want yeah that's great I mean I like the concept of a semi standardized mounting system you see that like all of the like airsoft people who put flashlights and junk on their they all have like standardized rails and it would be nice to take that out of the gun world and into into fashion pretty cool yeah I think I liked your idea I think you had last week where you can like print like a heel part and have like so you can mess with people when you're walking do like bear tracks or something so there's lots of ideas you can do exactly yeah so check out the fusing 360 file or the STLs you can modify it and attach any craziness you want to your shoes really cool thanks for showing those very exciting love it thanks guys good luck on getting your little spot okay all right let's see next up we've got Melissa oh and Paul came in there by accident I'm sorry Paul pull you back out so that was a false alarm Melissa hey there we go hey about Paul so I wanted to show I'm working on trying to get this Macintosh here all fixed up it still needs a new battery inside because it's dead but I got Mac 8.6 running on here it came with like 7.6 this is when I got like a few years ago as actually a gift along with some Commodore 64 monitors and I just did not even try plugging it in until just recently and so I've been actually having a lot of fun getting this up and running which model of Mac is that oh this is the Performa 6.1.1.5 CD you usually find them online for I don't know maybe 150 or something like that but it came with the monitor and stuff I had to get a new keyboard and mouse because I didn't have one of those and I actually replaced the hard drive with a SCSI 2 SD device so it's actually running off of an SD card a little quieter a little more reliable exactly definitely more quiet what's your go-to thing to run on an old Mac that you get do you have a game or oh actually the thing I was trying to get running on here was hypercard and because I wanted to play around with that so I got that that's why I actually had to go with the 8.6 because it was wanting to install something on the 7.6 that I didn't have I have to go ahead and it runs fun now I want an old Mac thanks for bringing that on and show us your hypercard stack when you get it finished okay I have to learn it first though okay there's your project alright next up we've got Scott here and oh yeah the cameras are moving I almost only brought on Scott's screen see it's tricky when people drop the little buttons move alright what's what's new Scott hey yeah I have been experimenting with MDNS which is multicast DNS which Jeff had brought up in February and did a PR and then we kind of didn't do it but it's pretty neat because you can you can advertise a hostname so you can say like I'm circuit python and then in a browser you can say circuit python local and you'll go to that web page for that device that's on your local network so I got to thinking it was talking with the more and I got to thinking we could use that for a web workflow so you'd be able to do circuit python local and then it would take you to like an editor where you could edit the code on any of your circuit python devices that are on your local network which I think would be super rad so I've been learning more about MDNS and what I've got here is MDNS is kind of created by Apple and so they use it in a lot of places and I'm adding a new MDNS module to circuit python and what I've got here is the output when I look for airplay devices on my local network using MDNS so you can not only can you do the hostname lookup but you can also say like hey who provides this type of service and so you can see here that I have like my Apple TV and my MacBook Pro are both responding to hey do you do airplay for example so this is how you can do discovery of other devices on your network so the idea being that you can use the hostname resolution to get to one circuit python device and then that device can look and find all of the other ones for you and kind of let you know what their name is as well so I'm working on adding MDNS support to circuit python really cool it's crashing a bit right now so we'll see how that goes and I'm about to have a baby but yeah it should be a cool foundation for a web workflow for circuit python maybe you're the MDNS the baby yeah maybe it's a great workflow foundation yeah no so yeah it looks pretty neat I've avoided doing a web workflow for a while and I think this is kind of that thing that can make it really easy yeah whippersnapper the work that Lauren Brent and Melissa have all done to make whippersnapper really easy has been really impressive and kind of got me like seeing an easy way to do web workflow stuff so this is a piece of that all right well thanks for that I'm looking forward to it and how soon until we are going to have Scott out for a while is that coming up pretty quickly here the baby is due a week from Friday all right best of love yeah the next few weeks all right probably stop on the MDNS for a little while just prepare mentally and emotionally yeah I'll be taking parental leave once the baby arrives fantastic good all right thanks so much Scott we'll see you soon all right next up we've got Jepler hanging out here with some cool hardware welcome to my upstairs so this is a PC floppy drive TAC model and I've just been writing a floppy to it using our experimental Adafruit floppy interface so I'm going to pull that out oh boy just next door look at this baby it's gorgeous slot that in there and boot it up we'll be surprised by what we see I mean not me I know yeah oh hey that's excellent yeah if you can't read that that's the Oregon Trail a classic educational title of the 80s downloaded from archive.org written to a new floppy with Adafruit floppy on a standard PC floppy drive reading and booting on a genuine old Apple II computer so I'm really excited to see kind of one more format checked off that's true yeah so that's what's up with floppy drives this week great work thank you for continuing to check off those boxes it's it's really impressive all right well I'm gonna go dive this and Terry go don't die make it make it west go west all right we'll see thanks come on JP all right let's bring Liz on here hey Liz I'm not hearing you now I bet I need you yep so just quickly want to show I keep on my desk handheld version of Oregon that's excellent yes I spent many an elementary school day playing that so one little thing I've been working on on the side is kind of a circuit Python based sequencer I really want to use this rotary coder that's in the shop and use a matrix as like a GUI so basically I'll just throw some random notes on it's just a C scale so everything should be fairly in tune and can you hear the figure? yeah really cool so you can slow it down to eighth notes or quarter notes if you're feeling really slow but 16th notes is really fun and then you can speed up the BPM or slow it down or if you really want to then you can use the scroll wheel and also add more notes so yeah it was fun figuring out like how to get the notes to stay on the matrix and also keep it scrolling and yeah it's just using the tone library to turn that note on the speaker oh that's really cool yeah you've gotten a lot of interface out of that click wheel like you're doing a lot of stuff there which is pretty interesting yeah so it's fun to play around with I'm hoping to maybe use this as a Eurek interface for sending out like one Vox sequences that's really cool oh I love that idea yeah and a great I love the matrix display for that kind of interface it's really perfect it doesn't feel like you're looking at a display exactly like 90s music gear kind of way it's really elegant I love it oh that's really cool you have a guide in mind for that perhaps I haven't chatted a little more about it alright well I put a vote for that because I'd love to see it and as I want to say it's my first week full time with Adafruit too way congratulations thank you yeah so exciting we're really glad to have you and looking forward to the kind of stuff you'll be doing with us so thank you so much yeah I'm really excited thanks Liz alright we'll see you next time see ya alright next up Paul I'm sorry I teased bringing you on before but here we are now good to see ya thanks for having me how's things what's new the third episode of the podcast the circuit python show came out yesterday with Professor John Gallagher of Boston College we had a real fun conversation about how he's using circuit python in college classes with his students I'm really looking forward to listening to that that's great and then next week we'll have Todd Bot oh good my good friend Todd I'm glad you I'm glad you're having him on so where can people hear the podcast where are you broadcasting to just search for circuit python show in your favorite podcast app we're everywhere we're on Spotify Google Apple podcast you name it we're on it how have you found is this the first podcast you've done it is how have you found the process so far any tips for people any lessons learned so far it's a little more work than you think you spend a lot of time researching every episode in your guest and what they've done so the time commitment was probably just a little more than I thought that's probably the biggest one but it's been fun I mean getting getting a chance to talk to these people in the community and getting to know them and being able to share that is really the goal and I think so far it's going well that's great now do you find that you're doing a decent amount of editing to get to a certain amount of time or a certain level of content like I've always wondered what kind of ratios people get with interviews versus what what they end up putting out we're using 90 to 95 of everything we talk about so you're hearing almost all of the conversation the only thing that might be professionally edited out is if we make a mistake and stumble over words like I just did but I actually pay someone to do it because I don't have those kind of skills and it's the same guy who does the editing for talk python to me the popular python podcast so he's doing a heck of a job it's funny occasionally I hear people do a retake and forget to edit it out they'll say something take that again they'll say something and you hear it it always makes me laugh great and so do you have a lineup planned out for a certain number of episodes already do you have a certain cadence that you're looking to get into to bank episodes for the future that's exactly what I'm working on right now so I'm calling a season approximately six episodes and I'll probably take a week or two off and then I'll come back with another six I've actually talked to so many folks that I'm probably into season three trying to book folks to come on and what is your background coming into this your interest in broadcasting as well as python you know we're in the middle of a pandemic and I needed a hobby no background in any of this I've never done anything like this before yeah oh that's terrific congratulations on the success so far and I look I've listened to the first episode I'm looking forward to taking some dog walks and listening to the next two and on into the future so thanks so much and if people over in the discord have any suggestions of people that they'd like to hear interview can they ping you over there anytime I'm always looking for interesting people to talk to great okay well thank you so much Paul and we'll see you soon thank you for having me all right now we've got make it hack in hello welcome can you hear me yeah are you great nice to see you so it's cool that you're running the show because I am showing off an update to my phone ringer yes excellent so it's a pretty small update but so this was version one and version 1.2 has a feather wing breakout so you can put a feather wing on this thing and if you don't have a feather wing you can put a lipo battery there a couple other things that I fixed were before I had like to do a bodge wire so I got rid of that and then not all feather wings have pull up or not all feathers have pull up resistors for buttons so or internal pull up resistors so I built it in so they can be added or something like that and then so I'm just demoing the feather wing OLED here and then these buttons are the same as these buttons so just demo of using the feather wing during it now so still works through the IO thing I haven't done any software updates but oh that's terrific I have I am looking forward to putting my kit together you were gracious enough to send me out a PCB so I've got all the parts ready and I'm going to build a bone ringer I have extra 1.2 so wait until I send you one of these so it has the updates on it so yeah really cool project for people who don't know who are watching this is not trivial to ring telephone yeah not at all lots of voltage needed lots of voltage some particular timing it's an AC thing right or a sine wave bang essentially two different magnetic coils back and forth it's not like you're going to walk up with a 9 volt battery and it comes up a lot for people who are doing theatrical stuff still as well as of course people want to do escape rooms or just have a conversation piece so I am so excited to put this together I'll wait for the revision on the PCB but really great work and for people who are interested you have a Tindy store is that correct where they can pick these up so they're not on the store yet I was waiting until 1.2 came out the 1.2 PCB just arrived this afternoon so it looks like everything works so they might be up sometime soon and can they check make it hackin yeah make it hackin.com got all my links on it and just for the people I guess who weren't here a couple or a few weeks ago whenever it was so this is a telephone ringer John said that you know it's not it's not trivial to ring it but just the setup that I have here is Feather goes here there's kind of like a spot if you do a stand off to put a battery underneath and you have a few buttons to ring a few different styles or whatever you want there's some indicator LEDs now there's a feather wing breakout you can do it from USB or you can put it on a battery I don't think the batteries last too long depending on the size that signal is fed into this boost converter boost it from about I think 4 to about 40 volts and then it goes into the Adafruit 8871 motor controller and then the motor controller signal from the Arduino or Feather and creates that sine wave then goes into the RJ11 jack and into your phone so that's how it works you go to I'll put the link in the in the discord but all of this is on github so I'll link that in the chat yeah so you've got things like US ring, British ring people with different patterns that are available that people could pick and it runs on Adafruit IO so you can ring it from your phone so cool you know that gives me a thought because I have a little alert that I've used during my live streams and there's a couple people who can use a glitch IO page to let me know if I've got my audio dropped because it's something I never use, you're mute for a while I should really switch that over to be a phone ringing because there's no ignoring that don't let him abuse it though you have to trust people with that awesome well thank you so much for bringing that on, great progress alright and last up we've got Mark hello so I said I'd bring it back the Game Turn Timer project that I've been working on is now in its final case and everything's working so you can set how many players set colors for every single player and then start finding out who actually takes the longest when you're playing your games and it'll just cycle through all this for as long as you take on the back now it's all on one of the PROTO boards which made it really easy to hook up the whole mess of wires which you can't really see clearly from all the segments on the front and the LED strips and the buttons yeah so it made it super easy to work I really like you did a thing there with the Molex connectors from your buttons didn't you so that you can plug them directly in the board so the blue LED button on the front screws in and I didn't want to have to solder it through and I had those arcade connectors which fit the button and then the other end was a connector that I just happened to have a spare connector sitting around that worked perfectly it's one thing that actually for a lot of people trying to build your first 3D projects that you print yourself it found was having like a bunch of connectors around is useful because you will mess it up and I have N trying to desolder it which is the worst thing in the world yeah sometimes it feels like about 25 to 50% of a project is interconnection of the wiring like it's just to get it right so that you're not hating yourself later you actually really have to do a lot of work to make interconnects happen yeah the wiring itself isn't hard it's getting it all hooked up but together and apart and together again yeah beta tested it with my friends playing a game this weekend and it's amazing how quickly everyone was as equally concerned about how long their turns were and yeah some suggestions are like you should figure out the total score divided by the time to figure out who's most efficient now they're gamifying the game timer of course yeah so we made a game of the game timer on top of it because we're a little bit too competitive at times maybe a separate device to do all of that work that watches the game timer excellent thanks and is this a project that you're thinking of documenting or putting up files? yeah I haven't documented yet I've got the code up on github if anyone's interested I'll post the link it's all done using the new async.io so it's a good non-trivial example of that which actually was able to learn a lot by doing it that way so oh that's great I'll post that link good yeah for people who are watching head to work discord to see where that link gets posted that's adafruit.it in the live broadcast chat channel alright thanks so much and we're gonna say goodbye to you and say goodbye to me because it is time for Ask an Engineer so thank you everybody who came and brought excellent projects thanks to everyone who hopped into the chat it was a really fun night of cool show and tell and like I said stay tuned for Ask an Engineer happening in right now bye bye
