I have made a 5-foot-long 2" wide flexible LED sign that wraps around a T-shirt. The LED array is 8x250 which is 2,000 LEDs and controlled with a Atmel ATMEGA168. The LED array will display just about anything from scrolling words to animation.

I am an electronics engineering technologist. I have a BSEET from DeVry University. I like making electronic hardware - I would rather build it in hardware then program in software! I like embedded systems (microcontrollers). I also like to fly high-powered rockets with custom electronic packages.
