I note that some of you guys have rigs where you can control the pan and tilt of the camera externally from the ground. Ive tried doing a search on this subject but didn't come up with much in the way of results. Maybe I used the wrong keywords. How exactly, do you produce these rigs? i assume they're all DIY - made from various parts rather than a single store-bought product. For a project I'm working on, I just need tilt for the time being. Are there any useful links for building these kinds of control systems? Though I admit my knowledge of electronics is just about 0 so that may not help.
