Apparently OP is not following this one, but I see that _some_ proper nouns are not capitalized (like github, singapore, overglade...) while others are.
Should I update my userscript to handle an incoming new trend?
Interesting... RP2040 seems like maybe a bit overkill for a zero power badge. I've participated in writing some software for an RP2040 powered badge for the RVASEC conference in Richmond, VA, for several years, and the RP2040 is really nice to program for, and is quite powerful. https://www.youtube.com/watch?v=A5ZrHAXCFLA
I have been looking at some other MCU's like the CH32 for future projects, so if you also have any suggestions for other ones, I'd love to hear them!
Do you ship internationally, also with complete setup of the hardware?
You can make it more fun on yourself if you want to assemble them by hand and it's probably a bit cheaper, and JLC will ship to pretty much anywhere in the world.
That's very cool. I have a few ePaper picture frames that don't use any power, and when you tap your phone to them it uses the power-over-NFC to boot itself and update the photo you send to it. It's such a cool idea and something I always felt like could be used more for displays that don't need to update very often.
Very cool! Quick question: did you use a plugin to generate the NFC antenna? The routing and layout looks nice. The end result is great! I bet it was satisfying to get it working on the first try.
I used https://eds.st.com/antenna/#/ to get an antenna that fit with a target inductance of 4.7uH and then used https://github.com/nideri/nfc_antenna_generator to create the footprint which I slightly modified for the board! You can read a bit more about it in the journal (JOURNAL.md)! It was really satisfying to get everything working (especially the NFC because I've found RF to be a bit tricky), but the eink logic…
Went to Treehacks at Stanford this Feb and they had PCB badges too! Gotta say these ones are much cooler tho :D
