After making two timelapse montages (see sgphotos.com/portfolio/timelapse), I'm going to integrate motion into my third video. Toward that end, I am building two devices: 1) A dolly that will slide the camera horizontally on rails, causing changing perspective between foreground and background subjects; and 2) A turntable that will rotate the camera through a fraction of 1 degree between photos so the footage will have panning. This video shows my progress on the dolly system.
Commercial versions of these devices cost hundreds or even thousands of dollars. Being a college student, I can't afford this, so I have been dumpster diving as many parts as possible. I'm using stepper motors harvested from scanners and gearing harvested from discarded printers. The motors and motion logic are controlled by an Arduino and MShield, which are cheap open-source microcontrollers. I control settings using a series of potentiometers and LEDs.
