Brief open-sourced motorized zoom lens introduction
While working on some computer vision projects I have been missing feature to control zoom / focus remotely. And I am not the one with problem like this. So introducing motorized zoom/focus lens with USB controller. While lens is manufactured by third party vendor, I had to make compact USB controller by myself.
Software is open-sourced under GPL license and initial version is already uploaded to github. Board software for simplicity written on Arduino platform (Atmega328). PC testing software is written in Python (theoretically all platforms Windows/OSX/Linux are supported).
