This is the best use of an old hard drive that I have ever seen.
This is a real 3.5 inch computer hard disk that has been transformed into a working desk clock using quartz drive movement. The clock measures 4 inches by 6inches and runs on 1 AA battery. The top cover of the drive is turned into a stand and screwed at the back allowing the clock to stand upright on your desk.
The hard drive clock is available in white and black and is priced at $34 ~ $35.
With some effort, I suppose it’s possible to create such a clock at home, using a cheap quartz wall clock. I have to try this with my old hard drive.
