Did you know that you can make light paintings with a long exposure camera? Light painting is a photographic technique in which exposures are made by moving a hand-held light source while taking a long exposure photograph. We take this a step further by finely controlling the light source's movement with a stepper motor driven rover. The results are stunning. The project consists of a Raspberry Pi 3, two stepper motors, and a Neopixel LED matrix. It can easily be recreated with a 3D printer and all of the code is provided.
