Speed simulator for racing games or coaster simulators

Step 2 How it works

a normal speaker, has a coil, inside a magnet. when current flows trough the coil, a magnet field is generated wich pushes the coil out of the magnet, moving the membran. then, the current flows in the other direction attracting the coil and taking the membran inwards.

if we apply this current coming from the hifi to a DC-motor it will only vibrate, and maybe play the music. basically the theory behind a DC motor is the same like on a speaker, but in rotary way instead of linear way. by adding the diodes, the current will only flow in on direction, so the motor is going to be "pushed" always in the same direction and not backwards. basically what happens is that when your car ingame or your coaster is going faster, the motor and the tires are louder, and that makes the motor spin faster blowing more air against you.

ATTENTION! this kind of propellers are only helt in place by pressure. the motor MUST spin clockwise (on a NORMAL propeller) else it is blowing in the wrong way, and the force generated by the air's resistance could make the propeller come off and shoot into your face! if the direction is correct, then the air is going to stick the propeller on the motor even more!
