Mini timelapse rail for travel with odroid-c1


holidays are coming. My big timelapse rail is about 2 meters long. So I decided to build a timelapse rail for our journey with the odroid-c1, a cheap stepper motor and a towel holder with pullout. In this case I use a smartphone as webcam, but also tried it with an old IXUS 500,  which is a little more complicated and not described here.
