It works like POI Spinning but with Digital LEDs in-place of flames. It was created using a Microchip PIC microcontroller and a small circuit board.
The Digital Poi Spinning device can write text, draw small icons, and display patterns as you spin it around. It works by encoding your visual data onto a series of 8 LEDs that are spun in a circle quickly like traditional a fire spinning POI.
