Motorized Camera Slider

This project builds on top of the original bluetooth motorized camera slider. Most of the electronics and hardware components are repurposed in this upgrade and uses the exact same code and software.

The Upgrade

The majority of the update is mechanical. The slider performs much smoother and operates with less friction in the timing belt. The entire slider assembly can now be mounted to a tripod! Two 2020 aluminum extrusions support the linear bearing rail allowing the assembly to be mounted to a tripod. Redesigned mounts reduces the amount of friction caused by the timing belt, allowing much smoother motion.

Prerequisite Guides
