Building a Persistence of Vision globe is pretty awesome, but overlaying a Death Star pattern on the display (http://hotchk155.blogspot.co.uk/2012/09/making-pov-globe.html) takes it to the next level of geekery. Like us, [Jason] has wanted to build one of these for a long time. His success pushes us one step closer to taking the plunge and we hope it will inspire you to give it a shot too.

As he mentions in the beginning of his write up, the mechanical bits of these displays are really where the problems lie. Specifically, you need to find a way to transfer power to the spinning display. In this case use went with some DC motor brushes. These are replacement parts through which he drilled a hole to accept the metal axles on top and bottom. We hadn't seen this technique before, but since motor brush replacements are easy to find and only cost a few bucks we'd say it's a great idea.

The 24 blue LEDs that make up the display are all on one side of the PCB. They're driven by an ATmega328 running the Arduino bootloader. [Jason] uses an FTDI adapter to program the chip. Don't miss the video embedded after the break.
