DIY Digital POV Clock On a Hard Drive Platter

This DIY digital clock takes Persistence of Vision (POV) hacking to a new level by combining the more common POV tricks based on a spinning old hard drive with a sweet digital clock display created through POV.

Watch the video above to see the clock explained by it’s maker and in action. Although the DIY guts are quite complex the premise of it is straight forward: there are LED lights under the etched disk that blink at the perfect time to shine through the numbers and create and illusion of a digital display. Hit up the link below for more details.

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.
