Light painting rig is a masterpiece of artistic hardware hacking
July 30th, 2018—
Light painting is an art form where dark areas are selectively lit to form interesting effects. While normally a manual operation, Josh Sheldon has come up with a rig to automate and enhance the process. The results are nothing short of spectacular, producing not static images, but astonishing animated light displays.
His device resembles a 3D printer made out of aluminum extrusion. X,Y, and Z axes are controlled by a series of stepper motors, but it uses a point of controlled light instead of melted plastic to form shapes.
Light animations are set up in Blender, and a hardware and software toolchain including Processing, an Arduino Mega, and a Dragonframe module are implemented for control.
