Build a Barn Door Tracker

Barn Door Mount - Manual Version

Manually Operated Version
The 6-inch long, ¼-inch diameter screw has 20 threads per inch. Combined with the geometry of the mount, this requires the screw to be turned precisely once per minute to make the camera track objects in the sky. A wooden handle at the bottom end of the screw makes it easy to turn. The tripod is held together with a sawhorse bracket.
