The “light orb” has become a staple of light painting projects. If you’ve ever looked through someone’s gallery of light painting, you’ve probably seen a few. There are multiple ways to make them, this project focuses on swinging a light, or multiple lights at the end of a rope while you slowly turn in a circle.
The addition of addressable RGB LEDs and a micro controller make this rig capable of generating patterns and possibly even simple images in the sphere itself. His results are quite impressive. His spheres actually look even more precisely shaped than the automated sphere rig we shared with you before!
