I recently built the solar engine shown below:
**broken link removed**
with a 3k resistor, a 4200uF capacitor, 2 calculator solar panels and an old CD player motor. Under a table lamp, the capacitor charges for about 25 seconds, then the FLED starts flashing, after another 15 seconds the motor spins. What I don't understand, is if the FLED is flashing then why doesn't the motor spin immediately afterwards?
