Devin just submitted this video to our Make: Halloween Contest 2009. It’s a Tesla coil activated by a relay controlled by a microcontroller with a motion sensor. As Devin says, the coil is “very loud and startling,” and he intends to use it in a haunted house. He’s written an Instructable, too. Zap!
