Pendulight

At right shows the initial sketch concept of having a dSLR capture the movement of a pendulum. There have been a few changes to the system from the illustration at right.

Updated parts can be found below. The plumb of the pendulum is equipped  with an RGB LED. The dSLR will capture the path of the plumb with a long exposure. The pivot point of the pendulum is on a multi-arm extension attacked to a stepper. The extension has three positions on each arm, allowing for some degree of adjustment to the physical system. Direction and speed of the stepper will be controlled through a toggle and a radial potentiometer.
