We have a homemade Sky Cam. The design is loosely based on a bicycle-powered railroad handcar. The problem we've run into the first few weeks is that the cables are attached to the grandstand at Enlow Field, which has a little give, so there is some slack. When the operator gets to pedaling too fast, it tends to bounce and flip upside down. With effort, he can get himself flipped back over (similar to a turtle). Despite typical parochial volunteer pay ($25 per game and dispensation from Sunday mass that week), we've had trouble keeping the position filled. On the bright side, we have some phenomenal shots of the Big Dipper.
