Wind Cannon 2 : Système de ventilateur PWM haute puissance pour simulateur de vent

Wind Cannon 2 is amazing and far easier to build than it's predecessor. I've done a number of wind sims including the Motion House units but, these things smoke them by a mile. VERY VERY loud though so if that's a concern then these might not be for you. Otherwise they are simply the best wind sim on the market.
