One of my latest projects has been a Cable Cam. A Cable Cam, as the name suggests, is a camera that runs down a zip line. Here is mine:
The trolley is made of
- 2 Clothes line pulleys
- A length of 2x2
- A bolt with washers on it to act as a counter balance
- A camera holder
The camera holder is made out of two pieces of sheet metal that I bent at school. It allows the camera to pan and tilt.
A 100ft line is stretched between two trees using ratchet straps. A second line is stretched above it to act as a safety line in case the main line fails.
The whole assembly can fit into a backpack. This makes it perfect for location shots.
Currently, you have to drag the trolley to the top of the line and then let it go to get footage. Eventually, I will get an RC car and use that to move the trolley down the line.
