'Sunflower' - Solar Power Smart Head V5

I made this bot for my daughter's 6th birthday present. I used as many scrap parts as I could scrounge up (Situation = Normal). Most of the capacitors are scavanged, along with the 3.5" Floppy drive motor coil, the leds, all the wiring and connectors and the battery. I made the frame around the solar panels out of copper wire and copper tubing, soldered together to create spring loaded hinges for both 'leaves'. This little guy will sit happily watching the brightest thing it spots, rotating to brighter sources of light, should they becoome available. He moves about every 4 or 5 seconds for about 20 degrees (unless he is locked onto a bright object) just slow enough to be plant like. He has a violet/pink led in the center of his flower and another red led on his radio shack round circuit board. I'll add a video when I get a decent one. Video added.

The schematic and layout.



Hinged panels demonstrated.
