Likely a huge hit at any Halloween party it attended, Casey Pugh’s Daft Punk helmet -
It’s a 16×5 LED matrix installed inside a cheap motorcycle helmet I found on Amazon. I used the Arduino to program all the animations. (arduino.cc)
The LEDs are on cardboard, so I punched holes between every single LED and some larger slits around the sides in order to see out.
Straight-up awesome. [via Synthtopia]
