This project first appeared in MAKE Volume 38, on page 97.
I was watching one of the new short videos for the GoPro Hero 3+ Black Edition the other day, and a shot of a skier had a camera move that spun around the skiers head, if you can picture it, my jaw hit the floor, followed by a bunch of speculation how the camera move was made. My brother Ty tipped me off to a shadow, that showed a helicopter like helmet attachment, where the camera was mounted on castor like mount, allowing the camera to spin around the skier, like bullet time from the matrix movies.
I had to build one, and with a simple goal of matching the shot, and making it as cheap as possible. This was all done with a trip to the hardware store, and about twenty minutes in the garage.
Check the above video at around 1:00 in for the swivel cam shot.
