My friend told me about the group "Daft Punk" about two months ago--I checked out their music, then saw heard about their helmets. As soon as i saw one, I was immediately attracted to it and it became my goal to make one. Originally, I wanted to have an LED matrix on it that could spell out words, but, in the interest of time (I needed it for a costume party), I had to cut it short to a "knight-rider"-esque display. There's a video below (mind the parents talking...) as well as details as to how it was made. I gave myself a $100 budget for the entire project (would've been a lot cheaper had I already owned an I/O board). I was just overbudget for the whole project by $1.61.
How it was made:
