HDD Clock – Persistence of Vision

1. Quite a few POV clocks out there, why is this special? Well, mainly because it's mine. There are quite a few POV clocks out there on the web using all sorts of display mechanisms, chassis, controllers. The one I decided to build isn't exactly one of them, the main difference being in the way I wanted to transfer energy to the spindle. This would add some originality to my project, sadly the method I chos ...
