  • This minature solar cell worked well for driving a couple of mosfet logic level gates, using only a hi-brightness red led. You don’t get much extra power, just enough voltage across a 1 Meg resistor to operate the gate. Previously, i tried the old “red led as a voltage generator” idea, but while that got 2.1 volts in sunshine, it wasn’t enough to activate the mosfet with only another red led as light source.

No public wish lists :(
