RGB LED Globe - Rotating Sphere [Project]
posted October 5 2013 14:28.52 by spic0m

An awesome looking project requiring both electronic and mechanical skills utilizing the POV (Persistence Of View) effect.
The LEDs are controlled by one ATmega328 with 15 8bit shift registers (74HC595) sitting on two PCBs in the center of the globe. The power is supplied via slip rings. The two PCBs and the mechanical part are self-made.
