 All right top secret this week first up Lady Eda is two leaks that you sent over one of them I'm gonna post up But one of them we already did so what's this one first? This is the MMC 5883 magnetometer So at first I thought this was like HMC 5883 Compatible, but turns out it's only pink compatible, but it's still kind of a cool little magnetometer So I whipped together a breakout for it and we're a library. Cool. And then what's this? This is the LTC 4311 this is interesting. This is an active Terminator which the whole word would not fit. This is this is like terminator TV. Oh, yeah So this is an active timer and very hungry So you actually detailed files is that a level shifter you actually plug it in at the end of your long I squared C string and it Like it's an active slew like Turn our honor so when it detects that the SCL or SDA line is being pulled high through like the pull up Even if there's a massive capacitance online because you have like a huge long cable It'll it'll Actively pull it up for you. It kind of does this smart little thing So you can use this for very long high capacity 40,000 picofarad Capacitance I squared C runs So I'm gonna prototype this send it out get it back I'm gonna try like connecting a hundred foot cable to I squared C and see what happens like does this work I don't know if I know all right, and then we have a little video that we shot This was the solar thing we're working on see on the other side. Yeah, what is this here comes the sun? testing out a solar charger got the solar panel And when I put the solar panel out in front and Check out my USB DC solar lipo charger that I'm designing an upgrade to the previous version This one's a little nicer has USB C in and then I'm plotting the power on this clue So you can see in this case I'm getting 2.1 watts out, which isn't bad. It's a five watt panel You usually get about half the wattage when you convert to lipo charging. So so far so good Thank you, Mr. Sam. All right next up on top secret. What's this? Okay? So the story behind this is is long, but worth it. So this is CID 5000s This is like incredibly old component This is an 800 by 480 3 by 5 3.5 3.5 Diagonal screens is used for like cell phones and stuff and my tft supplier said oh, you know I know you've been looking for 800 by 400 Displays and in smaller sizes and they sent me over this display and I was like oh my god it'll make such a cool like Raspberry Pi hat and They even like designed, you know, just kind of like add-on hat with the display and Like I made a little breakout to help me prototype it and like the sad thing is like I know exactly when I started this project because I've got the The did you keep a hag and it was four years ago But since I'm stuck at home now, we will get to I will get to yeah I was like, oh, it's only been like a year or two now It's been a quite a long time and and since then, you know, there's been like a whole bunch of Display hats that uses the DPI technique, you know, okay started to keep a like also like five or six years ago Like I'm pixel came in. I was like, well, I guess I don't have to do this but then It also didn't like the screen that was it had some blurriness to it I didn't like but then I found another supplier of a really nice TFT screen again 800 by 480 with DPI interface. I was like, you know what? Maybe like I'll try this again. So Over the weekend turns out that this screen has the same pinout as like a standard 4.3 or 5 inch TFT display, which is kind of sweet So you use like a these breakouts we have in the shop and then I have a trinket over here That is it sent the SPI commands turned on and it just turns it into a little live screen So I got this working on a breadboard And I'm gonna try to revive this project Maybe I'll have like seesaw connectivity and if we're felt like stomach you T connectors This is cool. But yeah, what's really nice is this is like a very Wide angle. I mean these IPS screens are so inexpensive. So like when I got this screen It was like, you know, 10 bucks apiece. This one's like four And incredibly cheap and get capacitive touch on them and stuff. So this is a really cool display So now that I have a good supplier of these I hope to do more with them and yeah, this is just the KEPA code But instead of having it on a keep I have it wired up to this TFT Okay, and with that is top secret Cool
