Thanks! Most of the electronic shelf labels these days are indeed eInk, so these were cool to see! The reflective backing can also be peeled off, making the screen transparent and allowing us to throw an EL panel behind one of them for that nice retro Nokia LCD feel.

That was especially cool, because the badges didn’t even have batteries. The bistable LCD just holds the image on the screen even after removing power, much like eInk/ePaper.

The badge was really fun to interact with! There was a unique QR code on the back that led you to a page that would allow you configure your name, text size and position, and which frame/background to use. Once someone did that, they’d bring the badge to our flashing station and we would update it!

I also had the opportunity to give a talk on it! Covered some of the previous work done by @dmitry.gr that allowed us to be able to do this at all, as well as some of the specifics about the badge firmware and other tooling we put together.

I was also able to get some of the CC1110 wireless stuff working! I sent out some SubGHz packets and picked them up on the Flipper Zero! 🐬

Since these are bistable LCDs and not ePaper/eInk screens, they refresh rather quickly while still holding a persistent image without power!

First step was “shucking” the case, which wasn’t too bad, but required destroying the front bezel. Then I designed a custom pogo pin programming interface in OpenSCAD and 3D printed it!

The case is glued shut, and the batteries aren’t replaceable, so these would effectively be e-waste. Hoping to give them a new life! They’re based on the TI CC1110 wireless microcontroller that a handful of similar electronic shelf labels use, so I’m hopeful on making some progress on them soon!

Passed so good they did it twice!

It’s changed a lot in the last few years, but would say all for the better!

Raspberry Pi Pico/RP2040/RP235x? If you’re trying to boot into UF2 mode (to copy over a new firmware), you’ll need to hold the BOOT_SEL button (if there is one) while plugging it in.

I watched this accidentally on loop a couple of times frustrated that it kept slipping on you! 😅 This is so neat!

I’ve got one of those here on my desk at work! I love it so much! They make a bunch of other cool ones too:

I don’t know why there are so many of these. I’d been searching for ones like that but with the CC resistors (or at least the pins broken out!), but there is always something that makes them less than ideal. These were the closest to what I wanted, but there are pads on the bottom and no THT holes.

Worked great, thank you so much! Excited to see what we get!
