From Jotunheim with love, it’s the Tesseract! It pulses with hypnotic blue light!
I put a copy of this board fully populated and programmed inside a standard acrylic baseball presentation case that’s been sanded inside with 1000 grit sandpaper and stuffed with synthetic batting.
It’s controlled by a hall-effect sensor, so there’s no external switch or anything else to detract from the presentation. Just swipe with a magnet to wake it, change modes, and put it back to sleep. It goes to sleep automatically after a period of time. When in sleep mode it only uses a few micro-amperes of current, meaning it’ll sleep for months at least.
Source code for the firmware is available at:
http://code.hix.io/projects/tesseract2/
You can grab a copy to compile and burn with mercurial by running:
hg clone http://code.hix.io/projects/tesseract2/
It should compile cleanly on Linux, OS X, and FreeBSD. You’ll need avr-libc and avrdude installed. The Makefile compiles, burns, and checks the microcontroller! :D
