I’ve often thought that hams should do more with badges, like they do at DEFCON and other hacker conferences. I had some ideas of designing my own, but then I found out about the Pimoroni Badger.
The Badger is a very cool, hackable, programmable badge with an e-ink display, with a Raspberry Pi RP2040 processor. It’s programmable with microPython, and in my case, I’m using the Thonny Python development environment on my iMac.
The e-ink display is a 296 x 128 display, and Pimoroni makes available a python program that does an incredible job of converting .png files to 1-bit grayscale images. Here are a couple of images I created for the Badger:
It even does QR codes!
I’m planning on bringing this to Dayton with me. A friend of mine has 3D-printed a holder for this which lets me power this from 3 coin cells. This should be fun!
