Just before 2012 steps in take a look at this POV clock. Someone already is using it to count down the time before twelve beats. Like all POV clocks – it displays time by spinning a set of LEDs. But like any other it has something unique worth mentioning.
It’s heart is an Atmega324P microcontroller running at 20MHz. Image pattern ins held in external 64kb Ramtron FRAM (FM1608) memory. High resolution of image is achieved with 40 Cyan PLCC-4 LEDs controlled via five TLC5916 constant current LED drivers. Power between motor and rotating part is transferred wirelessly.
