Last night's Dorkbot SF was Boing Boing in a box. First, Mikey Sklar explained how he implanted an RFID tag (a simple chip with a 40-digit number) in his hand. Then he showed off some projects using the tag, including a proxiity-controlled trampoline-triggered oven...flamethrower...thing. (The upshot: You jump on the trampoline, the flames shoot up.)
