After taking apart some old laptops, I was trying to think of what to do with the broken hard drives. I've made several things in the past from the magnets and such, and one of the cooler things was a clock.
The first step is to find a clock with a second hand movement that runs from one AA battery with a long enough shaft to go through the HD case and one platter. I found one at a Target store.
The next step is to take apart the clock and hard drive.
I didn't take pictures of the next steps, however you can imagine a mess all over the desk as I carved a space in the HD aluminum case nice and flat using a Dremel, then attaching the clock to the HD case with a thick cyanoacrylate glue. A milling machine is probably the best way to do this part.
Here's the finished product.
I've used a wire between two of the case screw holes for wall mounting, or the HD PCB can be used as a base by adding a small angled bracket.
I cut the alarm lamp and snooze button off since there wasn't room to assemble the alarm hand due to the thickness of the case and platter.
Enjoy,
Scott
