Inside a motion activated wrist light on Hacked Gadgets:

I find it interesting to see how inexpensive electronics are constructed. My daughter got this Motion Activated Wrist Light at a school event. All of the kids were wearing them so that every time they clapped in rhythm the entire arena was flashing with a pulse of light. She no longer wanted it so I thought it would be interesting to see what made this simple thing work.
