Steven decided to strip the drum trigger to see what was inside. He found piezo film which basically senses vibration. We rigged the paddle so that the film was placed inside a groove cut for it near the bottom of the paddle. It picked up the vibration and so we figured out YES the drum trigger is analog. Oh and when the vibration was sensed, the LED in Santa's mouth lit up! "Ping Pong, Santa's ON."
