Testing Out DIY Fast Panning Motor for Gopro

Inspired by some of the fabulous kayaking videos from Gnarlydognews.blogspot.com , I decided to try to rig up a fast 360 degree panning motor for my Gopro. He has some great shots where the camera pans in under a minute a full circle, so you start looking forward toward the bow, turn to see him paddling, then turn back to the bow. Unfortunately, all the DIY instructions I could find for cheap panning devices were for timelapse photos, that is, a full circle in an hour! Not for what I intended at all. After much searching I stumbled upon small music box movements that wind up (no batteries or wires to contend with), then turn back. Found one inexpensively and rigged up all sorts of mounts to make it work with my rig. It's not perfect, but for $15 worth of materials and a bit of head scratching, I have something that does the trick. See below (though an unglamorous shot of my overgrown, under-cared-for back yard.)
