Heh, in college a friend and I wanted to make make an "echolocation" headband that would allow blind people to "see" after watching the video of the young man who possessed this ability [1]. Unfortunately, neither of us had the hardware expertise to make such a thing despite buying a Lego Mindstorm and the accompanying ultrasound sensor [2]. Best of luck to you all! The difficult thing we found was teaching blind people how to use it.
