FreeBOT (work in progress)

Project

FreeBOT - Is a Biped robot designed in Google Sketchup and printed out on a 3d print. My aim is to make it Free to everyone to print and improve. Since I can't afford a NAO.. this was the next best thing :-)

Charge Capacitor with Solar Panel

Is anyone aware of a simple circuit that will charge a capacitor with a solar panel (Small one from calculator) and then discharge to an LED via a transistor when the capacitor get's fully charged? The point is to make the LED flash. The frequency of the flashes would depend on ambient light conditions (less light, longer charge time). The closest thing I found is the circuit bellow. Would replacing the +12V with a solar panel still make it work (just take longer to charge)? Also what is the N.C. symbol at the transistors base ?(No Circuit or Normally Closed???)

Something to keep your brain lubricated

This isn't robot related, but it's something to keep your brains flexible and well lubricated.

The programming, and sound.... just fantastic.

This also works as a good distraction when trying to work on your 'bot ;)
