Motor


I worked out I’d need abou
t 20 N*cm torque to drag my camera about - the motor came from Ebay, and runs on 4 AA batteries. It's powerful enough to lift the camera vertically too so allows for a variety of positions. Update: in testing while the motor will lift the camera, the load seems quite high. I may upgrade the motor to something a little more powerful.



Rails

I wanted this to be light and strong. I sourced 1 metre long aluminium U-tubes from Homebase. The edge pieces are aluminium trim, also from Homebase.



Platform

An aluminium sheet did the job here, allowing me to mount the motor securely. More of the aluminium U tubes made up the connection to the rails. I didn’t use any wheels as I wanted the platform to stop quickly after each movement.

Camera mount

A cheap one from Jessops did the job, it’s a basic ball mount for a tripod. I'll probably upgrade this at some point.



Timing belt/pulley


Another ebay purchase, the timing belt was originally for a large printer of some kind, but perfect for my needs. This is held in place with more sections of the U tube acting as a locking mechanism.
