Sunflower Robot

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 scavenged, 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 become 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 hack round circuit board. The circuit is named the Solar Powersmart Head V5 by Wilf Rigter


  1. Now here is a child who can not wait for show and tell. My Dad made this for me!
