Astrophotography Sky DIY Tracker
The Hinge Sky Trackers enables you to take photos of deep space while moving your camera in time with the rotation of the earth. A basic regulator circuit powers a DC gear-head motor, which turns a pair of gears that engage a curved length of threaded rod, and makes the hinge open at the correct speed.
You can build it in a weekend about $75 or less.
