 All right lady. What is this? Hey everybody and welcome to show in tal. It's me lady Ada with me mr. Lady Ada on camera control We're broadcasting here from our secret headquarters in downtown Manhattan where we have all the synthesizers Send them out into the world Get exciting little show where we're going to have some show in tal Checking in with people from around the maker community and seeing what they're up to so come on by We're here for another like Minutes or so We want to see what some ada-fruits are up to you and then we'll call them people from the community So come on by with your tronics. You're sewing your 3d printer retro hardware. We got a little bit everything Whatever you like. Okay. First up Joker Hi, so yeah, I'm the guy with the scent that you were talking about So let me show you my setup here a little bit I recently purchased this keyboard at JP's suggestion and i'm running it with the feather rp2040 I think it's called prop maker board here and the midi's coming in so no computer doing any of this power is coming from a usb power bank and I just got kind of a really Demented awful detune sound tonight for you cool So, yeah, let's get this going here and so with the you can't see it With this control here. I can bend the whole pitch of everything and with this one It's uh, it's subtle, but it's changing the frequency of the tremolo effect that's applied to the notes Yeah, that's that's a little hard to hear Anyway, so what this is is showing is a couple of weeks ago. I had implemented basic pitch bend and vibrato effects And that was nice But folks said well, we really like this idea of LFOs that we have another software where you can cascade them together to get different effects And so this is the next step on the way to that so There are LFOs you can connect them together and then the newest thing is you can do arithmetic so like if you want to have the the detune of a specific note be 112th of the pitch bend plus 1 of the frequency of the slider You'll be able to do that and then it just magically happens behind the scenes without running Uh, you know without putting it in your forever loop that you're changing these variables They just change themselves and oscillate and create richer or just plain old demented sounds It's it's so it's demented this this was not tuned at the factory, but that's like making it that way Well, i'm digging it. Uh, uh, you're you're totally symphon out. I love it Well, I appreciate the the folks like jp and Todd bot and mark and liz who just are a wealth of information about this stuff. Otherwise, I wouldn't be as far along as I am Okay, I feel like you can get spun up a lot faster and not get frustrated when you know people that are Also doing it because you can just kind of go through all the trial and error You can just kind of skip over that part and just be like this is the thing you get this is the thing to try out and Try this because this'll this will have that first golden five minutes where you're not like, uh Yeah, well, I mean, there's a great, uh circuit python library for getting the midi event sienna There's a great learn guide about that. So that's also a kind of a key thing and learning what i'm doing here I read this thing was where every hobby cost two thousand dollars and like someone put together It's like eventually it cost two thousand dollars. I think every hobby Costs time and it'd be neat to have lots of little things if if someone wants to get into like snowboarding Here's a here's five little things to do. So you actually don't give up right away and like blow two thousand dollars So let's see how far you get. All right. Well, I'll be uh, maybe submitting a reimbursement in place Is that a chord I think it is. Uh, yeah, send the reimbursement. Well, yeah for this Thanks so much. Uh, all right. See you Scott Scott what you got going on this week Hey, how's it going? Uh, I have two things to show. So this is the first thing So I was talking about flashing FPGAs from circuit python and and lemora pointed out that she'd really like Flashing just regular chips. They're flashed over swd from circuit python Um, kind of a port of the ita fruit dapp library So what we've got here is some output I have from circuit python where we are reading the identity identification of the chip which is an nrf 52 840 Some data about the flash size and then it's starting to program it. So I've been working on getting Programming nrf 52 840s from circuit python Kind of all at the highest level. So it's all bit banging. So it's it's going to be slow, but it hopefully will be reliable In those times where you just need to get your uf2 bootloader back For example, so that's the first thing and then let me switch Doing your screen up or you don't need to do it just me I have this I'm sorry. There's a reflection. Um, I on the blog. I saw this cool Weather display ignore the I haven't done the days yet The days are wrong. I like the long clouds long. Yeah Yeah, so like tomorrow is going to be cloudy, right? So I came up with I liked this design where it wasn't the same icon repeated every hour Um, and I've come up with a system where it's like for a given stretch There's like a background one that tiles like the long cloud That's a good thing. There's like two there's two icons that go in the middle of that span Um, which is cool. So you get the like the one sun Over here in the one moon in that area In the long cloud, there's actually like an extra dark part to the to the cloud there as well Um, and then I'm pulling it off Doing the days there as well. So I've been pretty happy with it. Um, this is on the inky frame So it's running on the pico w and this was the project that inspired the json stream thing I think I showed basping. Yeah Um, but I didn't have all the graphics kind of like nice enough that it's actually quite useful And I have a couple other things I want to do to it too, but um, it's neat to just kind of get that visual representation of the day It's a neat idea because we're all used to that with our calendars. Like if you block out days on your G cal it it carries across day to day. That's kind of a neat idea with right or where it would have like Because that's what I that's kind of like a long clutch. It's like, oh like because you're like it's going to be raining or sunny But like when and then you're like doing mass in your head. I would want to know if there's like three days in a row of sun Don't be kind of nice. Yeah. Yeah, totally. And then Same whatever. It's also doing sunrise sunset times as well. So there's like Night and day versions of everything too. You should think of like analog versus digital clocks, right? It's like digital You know dig your weather. It's like every hour. This is analog weather Yep. Yeah, and that's using seven color e ink. So it looks kind of pretty It's not using all seven colors because what do you do with green but? um Yeah, raining frogs blue yellow orange Black white what looks great. All right, and uh, congratulations Scott and everybody who works on circuit python. We are up to 400 boards On circuitbrakecloud.org. So we'll talk about that tonight on the show, but um neat work because more than half the boards aren't even ours Way more than half way more than a hundred So nice nice work bringing in lots of people lots of communities lots of companies lots of efforts to Get python on our hardware out there Yeah, hugs to silicon labs for being supporting us officially, which is cool. Yay. They actually came in and added support, which was awesome All right. All right. Thanks so much scott. Thank you scott. Thank you labs. All right So we're gonna go to mark then brent then dj divin and then joey Um, let's other folks come in but that's the lineup mark. What you got going on? Hey mark Hello, uh Well, I've been following all this synth work going on. So I'm just trying to bring it up. It's cool synth summer Which is hard to say. Yeah And all of this has got me interested just sort of you said about a new hobby It's just like you pick something new up and yeah Dive into it. We can do stuff with it now. We thought with you know, it kind of builds on the circuit python stuff We've been doing. Okay, so you got you look at you have something. Okay, so There we go I'm dealing with an echo to try to get the sound to you. So What I wanted to try to do is not just play the stuff that's Going on. Did you hear those notes? Yeah, okay uh But at the same time when I just got this controller I was looking at the different software available to actually edit music and the pads and I realized In midi, there's multiple channels and the pads can be different than keyboard So one of the things this keyboard is good for is playing drum beats So separate from the synth code. I'm playing wave files. So I can start playing drum beats and Because this whole controller's got a sequencer I can record something what they did just before and then start playing on top of it So you can have your whole little studio going And all this is just running on an m7 hiding out behind there That's cool. And that's pretty much it So the drum the drum sound is that coming from the keyboard or is that coming from the metro m7? It's all coming from the metro m7 That sounds really good. You got some good drum effects going on there Yeah, I Just grabbed them from one of the studio softwares that I got for free with the controller But it plays back and sounds amazing And then you can just layer on the keyboards on top All this You're using like the wave playback for The drum samples because there's just like drum and then you have synth. I am on top Yeah, through audio mixer. I got it to the audio mix. Yeah, that sounds great Yeah, it's worked really well Uh, especially with the sequencer for the drums and I could actually sequence audio or keys on top of that And in theory, I haven't tried this yet is set up two synth IO objects So play two dance turns As well as the drums No idea you'll have to ask jeff It might be time for me to announce like hey, if you make something With like synth and record Python send send the music in and maybe we'll use it for the intro music for our shows or something like that Let me have a go send us a song when you when you're confident in your in your in your synthing abilities Yeah, well, I'll have to play around if I've been more and see what I get out. All right Uh, thank you Okay, next up is brent then we'll go to dj divin and enjoy brent once you got going on How are you guys tonight? Good So similar to you guys. I have a new child in my life and I made a couple of displays. I don't know you're probably too bright One for upstairs Is that so you can see Oh, no, these are um, so you display photos of kiddo Yeah, so one's using a titano and the other one's using the three five Other wing display And then also I made a e-ink display oops So I can see where So, yeah It's been a lot of work Yeah, we have a little um monitor that tells us the temperature and then I noticed when um You know, you you put baby down for a little bit and the first thing you do is look at pictures of baby I suspect that's what happened to you It's like Ooh, that's a lot of work. I'm a little tired. I should go look at pictures of baby now So I made a python script and I'll try and post it later um to rip through a folder of your pictures and then cover them all to the BMP. Yeah the format. Yeah for the Your displays Yeah, okay, um What the other thing The other parent just to give people an idea of some like weird parent things So the other thing I'll take photos of her and then I'll show her the photos. I just took Yep, I've done that. Yeah, and she's like, hey, this is great. I know that I know that baby there I really do enjoy um taking video over though like when she's making all the noises. Yeah Yeah, did you see the um the little uh voice cactus that'll repeat back Whatever the the kids that threw on amazon for like 20 bucks. They're super fun Like they make noise and the make noise is back. Yeah, we gotta bring that back out Yeah, some some kids are terrified by some kids like it our kid likes it. So she'll like Um, I do want to say I really appreciate all your baby einstein stuff that you guys Yeah, we have someone also working with us. Um, robert She's gonna show how to take apart and and make more things to get rid of the default sounds Yeah, because I just think that's super cool and Now as somebody that purchases all that stuff Um I think the enclosures are like because this is the first time ever in my life that I've ever Had baby toys It's amazing that the the things that we were I was writing about at make magazine a million years ago It's like replaceable batteries screws not glues like all that stuff was contained in baby toys It's like these are really good enclosures. They're low cost and they're sturdy Um, I think we'll see some some parents songs are all the same. Yeah, it's and I understand It's impossible to probably license. Oh my god. I have been stuck in my head forever. Even when I'm at work I'm still singing my kids songs. Yeah, so that's one of the things that we want to do is have like just little portable things That all it does is play the song you want and then you can change it on your own In a pretty easy way using something like circuit my fun. All right I'm sure you're gonna look at baby photos right after this All right, dj devin and then joey dj devin. What do you got going on this week? Hello, and I do agree. I love the my little hacker stuff. Yeah. Yeah, that's fun Uh, this was supposed to be a workshop lamp and I got the radius wrong with the diameter and Now it's just this massive lamp. Uh, so I've tried to figure out what I could do and lazy susan That was that was what I came up with So it's a huge lazy susan You get thrown up in the air outside and then you'll get blamed for UFO sightings. That's an option I thought about that quadcopter, but I'm just not a quadcopter kind of person So this could also double as a like a little display piece Yeah, you can do something neat. Um, oh, wow, that's really big When a human arm is on there, I thought it was a little bit smaller. That's no it is massive Yeah, I got the radius mixed with the diameter. That's a bad thing. Don't do that You have to email your third grade teacher and tell her she was right. He crashed a probe on mars because of that All right, this is cool. Yeah, you could do some neat photos with that You know you could probably get some prisms or some little mirrors and like really light light up something kind of cool Yep, nice little display piece. That's what I'm thinking that or something for like the family room table kind of thing It's a massive ring. I'm not selling them. So it's just a personal project that I messed up and had to pivot All right, well, good People made those wall clocks that like I thought about that but I have so many projects. I'd rather just do this and then move on It's a transporter pad. I think it's done. Thank you. Thank you. Have a great day. All right, good work All right, Joey, how's it going? I just saw your um one of your projects online just a minute ago and I sent it to la more look really neat I don't know if you're showing that. No, I'm not showing that actually. I'm showing something. Uh also feather related though Yeah, so y'all stock the lcd feather wing and one of my goals for this year is making more learn content for the feather wings So people like know things that it's useful for so I did this little guy It's a one of your esp 32 s2 feathers with the integrated uh bme 280 And it's got a it's like kind of a temperature display like, you know updates every minute or now every 10 minutes And every hour it uploads a to fruit io. So here it's connecting to the internet Yay Got a little data and that's your custom lcd that you've got made. Yeah, this is the custom lcd So there you saw two of the indicators the wi-fi indicator and the uh data indicator and now a little Little half moon says it's asleep So it's in sleep mode now and it's going to sleep for the next 10 minutes And once an hour when it wakes up and realizes. Oh, it's been an hour It'll log the data to a to fruit io And I just like the idea of making this a really really compact. I mean, it's using that little 400 milliampere hour feather battery. So it's a really small thing Tock the battery in in between that's kind of what it was designed for is to fit between the two boards But I'm a little paranoid about that because the the stomach qt connector inside kind of sticks up a little bit So I'm not sure my clearance, but I could try I could try that for sure Um I wrote up a on the user pages on learn guides. Uh, I wrote about kind of a guide. It's almost done Uh, and I'm just kind of working through like the low power stuff right now Uploading or updating every minute it lasted about a week on this 400 milliampere hour battery But I'm hoping that like updating every 10 minutes now maybe it'll last a little longer So yeah, you know and I'll paste paste the link to the learn guide in the uh in the chat But that's that's what I've been working on just uh Yeah, also, you know, we're still user pages are still really new but um, we we love you're we're one of the Most prolific just some really good guys are good guys If you want us to promote it on the blog to send it over and we'll be like, hey, here's a cool user guide By the way, anyone can write these I wanted to make it so people could Write guides without necessarily having bits on learn.aford.com because the editors, you know We worked on the editor for so many years. I think it's really the easiest way to publish I love the way you can put like like it linked to individual products and like it actually makes a it's a lot It makes a lot of sense the way the blog face You can like drag things back and forth, but We had one customer one of the most prolific guide writers in the world. So we can embed code We built it around we built it around You know, how would lady aida use this? Yeah, we tried every tool out there So it's totally like written for me like I'm one who's like a bigger like or scott was like I want markdown support He's like, okay. Now you can write markdown. We have to markdown style So, uh, you know, whatever you want, you know, it's it's possible to add it So let us know when you feel like it's ready. We'll promote it We'll let people know that this is one of the one of the first user guide content Pages that you've written. All right. Well, thanks y'all. I'm very good. Very cool. And good to see you again. Jai Bye All right, everybody that is our show and tell this week. Thanks so much for joining us A lot of people haven't seen it a bit favorite half an hour of the week every single week Um We're gonna do ask an engineer. We'll have some uh co-hosts and hosts uh on show and tell And then I'll follow up on ask an engineer, but just for the folks who are staying here to the end Facebook mistakenly labeled the show and tell is hate speech So you weren't able to watch the show and tell uh last week Uh, but they've backed but they fixed it and we got a very, um Uh, terse note. Sorry for the mistake. So I'll talk about that. Um, but this is all wholesome people sharing good stuff um Ain't no hate in here. So I think the algorithms, um, got out of control and uh, now it's okay again Some humans were needed to uh write the ship again. So anyways, we're back. So if you're watching this on facebook, welcome back See everybody in a couple minutes That was your tell. Yeah
