Here's Instructable on how to recycle old computer Hard Drives into very original looking WALL CLOCK.
Step 1: Materials and Tools Needed
Tools that you will need for this project are:
1. Drill - I would suggest small DREMEL type drill with bench press.
2. Some Drill bits
3. Kit of Screwdrivers, type and gauge of screwdrivers may vary depending on Hard Drives you use.
4. Small Pliers
1. Old computer hard drives, preferably 3.5 inch. The more you can source the better.
For this particular project I used 12.
2. Standard basic quartz clock movement, you can buy this at local electronics shop such as Maplin in UK, or butcher some other wall clock. For this project I have chosen to buy part as it only cost 2.99GBP
