Arduslider

This arduino controlled, motorized camera slider uses both 3D printed parts and and 3D printer parts. It costs a fraction of the price of commercially available sliders and can be modified to suit you.

The video below was shot at Dartmoor National Park using this slider. The last 2 clips were done by combining this project with my earlier D40 remote hack to create a moving time lapse. Please view it in 1080p if you have the bandwidth…

The dual rail design was inspired by a cliff elevator. The beauty of this design is that the two slider heads move in different directions and allow a camera to move further for a given length slider. It later came to light that a start-up on kickstarter had already implemented this design and had started the patent process. It looks like a really nice piece of kit, however it is far beyond what I was willing to spend with my limited filming experience.
