This is a polargraph (drawbot) "gondola" for drawing "light paintings" with an LED. It uses the polargraph's "pen lift" servo to turn the LED of and on, so no changes to your polargraph's firmware is necessary.

Info about polargraphs can be found here: http://www.polargraph.co.uk/

Light paintings are slow shutter speed photos, usually in a dark environment with moving light sources (or a moving camera). With this gondola and a polargraph, you can render photos or SVGs (vector art) with a small dot of light. Slowly.

www.thingiverse.com/thing:38216 Parametric Battery Clip by holgero was the basis for my battery holder. Thanks, holgero! I rebuilt the mesh entirely and changed the design somewhat, mostly to make wiring easier and battery removal less a struggle.

Materials and methods

- 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:
