Ultralight Camera Slider

Jim and I wanted to make a camera slider that was light enough that we could take it on the JMT.  We made one that weighed about a pound (1 lb 5 oz), and works well with cell phones and gopro cameras.  It cost $25 for the motor at Servo City. Here is the slider being explained when we were at Crabtree Meadow while hiking the JMT, and a few examples of videos made with the slider.

The end blocks are 3″ x 1.75″ x 10.5″, styrofoam covered by coreplast, glued on with Gorilla Glue.  The poles are aluminum tent poles.  The legs under the end blocks are tent stakes. The motor is a 12v 1 rpm motor from servocity.com, part number 638150, $25. I think next time I’d try a 2 rpm motor.  The motor is attached with zip ties as shown below.  I put a guide bar on the top of the block to feed the line onto the middle of the drive shaft.  There is a rubber washer on the drive shaft to keep the line localized on the center of the drive shaft. The camera platform is a single thickness of coreplast, 7″ x 5″.  The ball joint is held on by three plastic bolts. I already had the ball joint, so it didn’t cost anything.  Total cost to me, $25.
