Magic Lantern firmware

I reverse engineered the firmware in the Canon 5D Mark II and started the Magic Lantern project that is now an open system for writing extensions that run inside Canon's DSLR and mirrorless cameras.

Octoscroller board.jpg

I designed the LEDscape "cape" for the BeagleBone Black's programmable realtime unit (PRU) for driving RGB LED strips or matrices. I've used it in several LED art pieces, Cubescroller, Octoscroller and the Mini Pyramid, and other people have used it in many of their own art projects.
