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.

I do appreciate the input. Is there anyone that knows how to craft something close to what I asked for. I have seen some great stuff on here and don't think it is out of the realm of possibility.

Can you get the use of a video-camera & tripod? Maybe you could see what a web-cam & a laptop will do? The best approach is often to start playing with what you can get hold of and develop it from there.

How about marking the poles and using a camera on rapid digital shoot? In that way you would also see the jumper's technique and be able to give feedback on the jump.

Thank you, very good idea. I just have to see how many frames per second a reasonably priced camera will cost.

Then again, video cameras can be quite cheap. Considering how short a jump is you could get a lot on one tape / storage device.
