Hard drive clocks are a dime a dozen on sites like Etsy, but Hacked Gadgets reader NatureTM went the extra mile and employed an Arduino to control the time and LED light show on the reflective platters.

This is only phase one of NatureTM's project, a chronodot (for time accuracy) and a case will eventually be added. Details on the build are pretty basic at the moment, but a schematic can be requested and code should be posted...eventually. [Hacked Gadgets]
