You just replaced your laptop harddrive and wish you could do something useful with the bad drive? Make a interesting coaster to place under your drinks and impress your geek friends.
Step 1: Get Some Sticky Feet
Go to your local hardware store and get some self stick feet to put on the bottom of the harddrive. These will protect your nice table from scratches and keep hot or cold conduction to your table top. I got these from Dale Hardware. They are about 1/8 inch high.
Step 2: Stickem Down
Peel them off and attach on the bottom corners of the hard drive.
Step 3: Done
You now have a really neat coaster! Use it.
