The idea of this was to create ac power to run a voltage multiplier...i used a battery to run a motor, the spinning part is connected to an identical motors "spinning part". the two wires leading from this motor(which usually supply power) are now or course outputting a small amount of ac power. each one of these connects to the base of two separate transistors which have their collectors connected in parallel to a 9v battery. the emitters of these two npn transistors (which should supply larger amounts of ac voltage) each are connected to one of the inputs of a voltage multiplier.( i built this with np ceramic caps im not sure if that might be the problem). from this point the obvious problem is that we do not have a complete circuit. so the two lines from our motor each connect to another npn transistor (the same model as the others). The collector is connected to the opposite side of the voltage multiplier when compared to the other transistor(which is connected to the same wire from the motor) and the emitter runs back into the negative of the battery. the idea is that no current flows until the motor starts. This opens up 2 transistors; the first allows the current to flow into the voltage multiplier and the second allows it to be a complete circuit which runs back into the battery. im sorry if this was complicated.... i just don't know exactly where i went wrong... any help will be appreciated! THANKS!!!
