Need to build a device to measure verticals Answered
What i need to do is possibly use lasers, i need about 30 of them around a half inch apart inside an aluminum pole or something. then i need a light connected to each one which will be at the bottom of the pole. After the beams are broken i need a sensor to light up to tell me the beam has been broken. this way an athlete jumps and once his fingers break the beam i know how high he has jumped without having to deal with the vanes in the current device. just push a button to reset it all. no messing with the pole or vanes or anything.
