    Electric Bicycle Controller Board

    My electric bicycle has stopped working. I have checked* the voltage regulator (7812), the Dual Schottky diode (MBR20100CT) and the NMOSFET (RFP70N06). I haven't checked the low power chips which I think are unlikely to break. These are a pulse width oscillator (TL494CN) a dual op-amp (LM358P)...

    IC555 - control pin

    Hello everyone. I'm wondering if (how) could i make it possible; I have simple circuit from two parts: one stands as PWM oscilator (555 timer) and that timer drives the transistor (npn, let us forget about efficiency for now) On the CE line of transistor i have connected a DC motor of which...
