I need some help with a circuit. Im trying to make a circuit that will fade in and then fade out an LED, and then stay off for several seconds before repeating. I'm essentially making a fancy LED Throwie that blinks intermittently with a fade.
I thought of starting with a solar engine (http://www.beam-online.com/Robots/Circuits/1381.html) which I should be able to tune to get the intermittent blinking, but I can't figure out how to modify this to make the LED fade in/out. I need the circuit to be small and cheap, so Id like to avoid using any sort of programmable logic.
Any ideas would be appreciated. I'm not very good at electronics.
