SmartCap solar engine


Posted on Jan 23, 2013

Here`s a circuit diagram (originally drawn by Wilf Rigter, I corrected it based on Bob`s on-list feedback) for Bob`s `Vore-N-More` circuit containing the SmartCap solar engine: In this diagram, the `SmartCap` is just the 1.5 F storage capacitor, phototransistor, 2N3906 transistor, and 5.1K bias resistor. The idea is that after charging, a loss of light causes the 1.5 F capacitor to be discharged through the 75 Ohm resistor -- this gives the photopopper a sudden `recharge,` which it can use to get to a brighter spot.
