FLED Solar Engine
Parts -------------------------------------------------------------- Solar Cell 2500uF to 10F Capacitor NPN 2N3904 Transistor PNP 2N2906 Transistor FLED, Green, Flashing LED (aka; Blinking LED) 2.2K ohm Resister Motor
Notes: The FLED version of the SE is less efficient than the 1381 version. The operation is basically the same as the 1381 version, but uses a FLED instead of a 1381 Voltage Detector. Check out some solarollers I've built with this circuit.
