Persistance-of-vision LED Sphere
Posted by admin on June 10th, 2008
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. Although the system consists of only a single ring of LEDs, the high rotational speed makes it possible to display any combination of red, green, or blue pixels along the surface of the resulting sphere.
