Yes, the barn door tracker mounts to a tripod and the camera is mounted to the top plate of the barn door. The axis of the long hinge is aligned with the north star and the angle is changed turning a long bolt. The action can be motorized or you can turn the bolt manually. There are a number of hobbyist pages on the Web with DIY instructions.
Astrotrac sells a very slick product that works on the same principle, but the cost is almost as much as a used camera + O-GPS1

Another option would be to buy a used telescope with motorized equatorial mount and mount a camera in tandem.
