 Okay first up for top secret. We have this DVI thing then we're going to do some updates big update with some toy hacking All right. Let's see. Oh my god. What is this? This is one of our TFP 401 based HDMI TFT backpacks you got HDMI input here converts here into a 24-bit TTL display and When you click the HDMI, there's this extra little e-prom here. This is a 5-pin 24 LC or 4 or something And this contains the ED ID That's the thing that allows whatever the computer is plugged into this monitor to know that this is an 800 by 480 Resolution display and you have to add this ED ID program So normally what we do is we have like these pins here You see and then we connect to it with this Arduino shield and I use this to burn the ED ID in because the TFP 401 has nothing to do with it. It's it's completely separately connected But this was really annoying because you'd have to like program this and then you'd have to test to make sure the ED ID got Programmed so what we would do is you plug it into this Latte Panda, which is a Windows 10 computer And then you can see the display is is there five inch version of this backpack Wired up and you can see a nice 800 by 480 display and I wondering why don't you use a Raspberry Pi the Linux? Caches ED IDs and so you can't use it to test ED ID burning something that I learned kind of by accident one day But now I've learned my lesson so now always use Windows because always catch gets the ED ID fresh But I want to make it even easier and better So now I've got my RP 2040 feather with DVI output and it's got that DVI connection here So instead of using this kind of fragile Windows computer and a separate forward I have one design you plug it in and you can get to the ice with COHC MI So I press the button and it will Come to the display find the e-prom program and verify it and then display a nice colorful fish tank So you know that displays working so all in one ED ID burning and Testing so making stuff easier to make here at the Adafruit shop Okay Okay My little first let's do the little video from Jepler. This is some bear stuff And then we're gonna go into the update for the baby Einstein Take a long okay, bear it away All right So that is the update on if you want to do some puppetry make your own like Chuck E cheese animatronics pull the fur off of it Make your own little device use chat BT chat GPT generate text then do text Write your own story. Whatever you want to do It's now possible that bears are on eBay for like 20 bucks even less to shipping and then our big update is Big Stein take along music tunes like part four in this series Okay, so we said we're gonna put a circuit board in the side of it so you can have your own music and sound Okay, so The Einstein take along tunes is it's actually like I looked it's like one of the top toys for sale. I'm like I'm this is the fault issue if you have a kid. It's pretty so Normally it looks like this and it's got these like beads so I don't I can play with it There's a one Switch that can go from high volume to low volume. I don't think it's gonna come through because there's noise canceling But it plays like Music tunes And it plays that kind of like you're gonna your generic Classical music William tell over to your type stuff. I mean, it sounds really good. The audio quality is really good But the audio cannot be changed and like the first thing when we got this When baby Ada was three months was like, oh my god, I gotta like put my own tunes on it I can't believe it. You know, you can't customize it. The case is really nice It's got like it's battery pack this switch. It's like really rugged Also has songs she likes now so we wanted to be able to take those with us for a very single serving device Yeah, we have the board. Okay, so what we did in previous Yeah on previous versions of Mital hackers we took This apart opened it and this was The board inside so not surprisingly There's an epoxy blob There is a there's You know a couple only there's like three LEDs one red one green one blue Kind of lame so you can see the LEDs here here in here I'm actually kind of surprised that these are true LEDs and not just like wire bonded on I'll go only a couple components and then you know, there's the the switch Which we have to recycle and like maybe because switch cap converter here and And a last and we're button here. So we took this out. We scanned it and retraced it out and then we decided, okay Let's let's try using an ESP 32 s2 and we like soldered one in and got it playing to the speaker and verified it can go off the battery So the next step was we were going to design a new PCB So I think like two weeks ago. I showed off the design for the new PCB it's Here it is what she'll show it here. This is what it looks like So I designed a new circuit board which is the same Overlay actually didn't come out too bad has the same holes and cutouts and then the elastomer is in the same location It was great with a scan because I just traced it over Has an ESP 32 s2 a micro SD card so you can store songs on it USB C for loading Data on and also programming it stomach qt in case you want to like add some sensors or something Boost converter so it can run off of these are the the two battery connection tabs. So when you open it These tabs over here get soldered directly to the circuit board and then it'll get boosted through to five Sorry to 3.3 volts Here that can then drive this ESP 32 s2 which means you can the reason I went with Wi-Fi so you can wirelessly program it because once it's in the case It's really hard to get to like you don't want to keep opening it every time you want to change songs or change the code So you can use our Wi-Fi workflow to wirelessly program it and of course neopixels So we've got five neopixels almost twice as many LEDs and their RGB so you can have way more colors and then this is the Replacement hold on I snapped this on a little bit So this is the replacement And it just snaps and I didn't put in the screws But you don't actually need the screws and then the last one here. So I'm still working on The battery booster. There's something not quite right with the change over I think one of my resistors is the wrong value or maybe I didn't check it right But we're gonna have this for sale in the store by the way. Yeah, yeah There's gonna be this is a product We want to make a bunch of circuit board designs so people who want to get into product development people who want to make One of these for someone they know. Yeah, but also just to give you an idea of the types of things that you can do With existing enclosures. Yeah So it's soldered into the battery tabs here Again, the booster is not quite working, but it does work over you. You know, that's part of the Increvation process. I only got one. I got one way of going so so we have a light pattern Which you know, of course, it's gonna be way better than the default toy thing Yeah, we also have so you saw it's running the song that we put on there, too It's running circuit pythons. You can see the activity light. So I wish quickly My son powered baby toys. That's right. Dan Halbert quickly did a board definition for me So all of this stuff is working Plugged an SD card and what's really nice is you know, it's I want to actually use chest upt to be like Hey, can you write the code for me? And it wasn't completely right, but it like I could copy and paste the lines I didn't have to you know, write all the code from scratch. It was actually my code I just didn't know where it's on the learning system one of the 4000 guides So just to show like here with the top on and then You know, this is the RGB LEDs lighting up. So you notice that the original PCV didn't come out to the left Yeah, this is wedding. This is the It's what's it called. It's a bird. Oh, it's like the chicken dance I think it's JP song or can song somebody. I don't know who wrote it and then The second song is stored on The SD card so I'll I'll play it again and then I'll hold it up wait You do have noise canceling going on So right now the the button I knew the overhead so the button does Play pot, you know, there's only one button. So just play pause It's also used for bootloader mode and of course all You can see the LEDs. So the LEDs can actually do some cool stuff I might have them do like an FFT reaction so they react to the music So the good news is that you know, a lot of the hardware works You know, I can upload the I2S amplifier and this is using the built-in speaker, which is not too bad The I2S amplifier works and the SD card works and the ESP32 works and the Neopixels work And then this is a recent button, but I still have a little bit and the last one is good So you have to figure out this boost converter probably do another board spin and then I'll probably be done but so far It's working really nicely and I like it fit if it just right into the all the slots and dots Yeah, and then just you know these everyone they're everywhere they're low-cost and You know, you can hack and mod them you can make it so you have your own single serving music player, too Yeah, so we thought that was a neat idea for people learn how to do all this stuff How do you learn to be a toy designer? This is a way how do you learn to make all this type of stuff and have your like Trunks fit into enclosures So anyways, so so interesting stuff. So yeah, we'll be yeah That is what I come weeks top secret
