A prop needs to point in to the wind, the usual way is to have the motor vertical with three half spheres (half table tennis balls?) on horizontal shafts set 120 degrees apart - this way it's not directional.ala199 said:I'd like to build weather station, what could meaure only wind speed and then draw a graphic on a PC monitor. I'm thinking of useing micro motor and prop to generate voltage. Maybe someone has better ideas how to build it. :?:
Sorry to stray from the main topic at hand.being a kitesurfer and some one who is constantly watching the wind i have looked in to anemometer quite a bit.
