Get the base for your own GoPro motion control rig for awesome time-lapse photography using G-Scale toy train track to control the path of your camera. The rig has a controllable speed between 1" and 4" per minute using a sub-$10 toy kit gearbox (use a different gearbox configuration for speeds outside this range.)
