[Ivan] likes to take time lapse videos. Using his 3D printer and a stepper motor he fashioned a rig that allows him to control the camera moving any direction on a smooth floor.
The dolly has a tripod-compatible mounting plate and scooter wheels. An Arduino runs the thing and a cell phone battery provides power. A pot sets the speed and [Ivan] provides code for both a linear pot, which he suggests, and for a logarithmic pot, which he had on hand. You can see a video of the results below.
The device looks good thanks to the 3D printed body; [Ivan] provides the STL files if you want to reproduce his work. You have to print several of the parts multiple times.
We’ve seen good looking dolly rigs made of wood, if you are better at woodworking than 3D printing. We also saw a less-polished looking set up using Makeblock.
