Build a real hard drive clock

Build a Hard drive clock Part 3 in ‘Things to do with 20 hard drives’

By Christoffer Järnåker

If I say ‘Hard drive clock’ then you’re going to say ‘What’s new about that - it’s been done a million times’. Yes - but not like this! A normal hard drive clock would be using the disc as background plus the regular hands for hours and minutes, or you could lift the lid of the hard drive and drill a hole all the way through engine and all (kind of) and then mount the regular hands. Boooring! My goal - a wall clock that only shows pieces from hard drives. No plastic hands here please. Thanks Joe and Curt for the idea!

Well, with the wonderful bearings in the arms to the heads it shouldn’t be too difficult use the arms as the hands of the clock. So let’s do this! After taking out two heads I noticed that they’re from two different hardware revisions. One is for three discs and the other is for 4 as you can see on the picture.. I think that will only be cool that they look slightly different. Needless to say you will need to be careful when handling the heads as the tip will be damaged easily. Cut off the excessive cable piece but be careful so that you don’t damage the wires that go out to the head - it might stop working you know…

I got the clock mechanism from a old clock that I even forgot I had, even though it was hanging in my office. The ring that attaches the ‘item’ to the clock is very small as you can see on the picture. The discs hole is a lot bigger and what better to fill the gap then the original ring that holds down the discs in the hard drive? It’s a bit tricky to centre it but with a bit of patience you’ll manage just fine.

   How about a walking robot. Just use the Arms to cylce around in circles. You can create either a six or four leg model. You could also ad some basic remote control system to it.

   If you were really adventerous you could also use two arms and create a joint in each of the legs.

   How about using three running hard drives as a clock? With three HDs, each with their own controller and driver software, you could maybe get the arms to tick like second, minute and hour hands.

   Great idea. Looks 10 times better than simply sticking a few clock hands on it!

   The huge hands take away from the good look. You should try to seperate the r/w arms to make them a little thinner!

   Do you think a clock mechanism from a hobby store would be strong enough to move those arms?

   Is there any way to make the glowing (mountable LED with switch that control light on and off) and the acrylic case to cover and hold the Real Hard Drive Clock in the place.

   Any Suggestion?
