Of course the energy of a stepper motor now we can produce, but how do I use it? -Quite simply, you need to put the rectifier and regulator
Usually with a stepper motor out 4 wires corresponding to the two coils. Therefore, the figure two rectifier unit.
Our generator can produce up to 50 volts at high speeds, so it is necessary to take the capacitors voltage is below 50V. A voltage stabilizer at 5-6 volts. What good is our hack? -The fact is that even when starting off our lantern shines brightly! And in the process of movement and does not flash does not go off.
