Evil Mad Scientist Laboratories - A Simple and Cheap Dark-Detecting LED Circuit

you know, there are times when you wish you would have published things when you came up with them. grrr, i remember getting exactly this circuit when i was experimenting with FLED based solar engines that had photovore instincts built in.

but hey good for them! and i hope this simple circuit gets some mroe use, perhaps built into a solarbot circuit to add to a night based animatronic.
