Persistance-of-vision LED Sphere
Posted May 15, 2012 by Chris
“The goal of this project was to develop 3D spinning mechanism capable of displaying smooth video or static images. The device uses a spinning ring with tri-color LEDs inside, and relies on precise angular sensing and persistance-of-vision and to create the effect of a spherical display surface.”
