I aim for it to be a simple method of recording air movement. My first idea was to measure wind speed using a "vane" on a spindle, which would rotate because of the wind to give me a reading of how fast the wind is going. I initially thought that I would be able to do this with a "light gate". I would set-up the apparatus so that every time the vane would spin it would break the "light gate's" beam. I would measure the amount of times that light beam is broken a minute; therefore working out the speed of the air-stream I would have hoped to wire this to...
