Here is my LED cube based on Alex the Great's Awesome Led Cube.
I used a premade plexiglass cube
made for holding an autographed baseball ( golf ball ones
work better but I had a baseball cube and it works better with the parts I used). I used one 2032 3v battery, a battery holder
from Radioshack, a push on push off switch
from radio shack, an 4800 mcd LED from Marl
, and wire from radio shack for the circuitry. I added reflective alluminum from a kalidescope and made a cone from some flimsy reflective plastic to spread the light that is sent from the LED.
I am having problems with the slideshow right now if you only see the robot.
