"I did a full lap, plus a little bit to show how it performs on different parts of the course. It's really shaky on some of the rough stuff, but I think it does pretty well for most of it. My camera does 1280x720 res video, so it gives a good fullscreen to watch while I'm riding my rollers.
The mount is just a reflector mount with the reflector removed, a 1/4" thread bolt and a couple of steal washers and a couple of neoprene washers. I got the reflector mount for free, so the total cost was about $1.50 at Home Depot."
