- Micro Servo - Wire (I found stranded easier to use than solid) - 5mm LED - A resistor (of a value appropriate for changing 3V to whatever is safe for your LED) - A potentiometer (10mm square, mine is 10k ohm) - 2 AA batteries - A polargraph (either a kit by Sandy Noble, or made with an Arduino and adafruit motorshield - more info here: http://www.polargraph.co.uk/ Hopefully more instructions will be forthcoming. Questions can be asked on the polargraph forum in this thread: http://www.polargraph.co.uk/forum/polargraphs-group2/building-hardware-forum3/kongos-led-gondola-for-light-paintings-thread251/
