If you like electronics, you definitely going to like making a stylish dimmer switch out from a dead hard disk platter.
Step 1: Materials
1. Hard disk drive.
2. Rotary tool. (with diamond bits)
3. Dimmer switch.(you can make this but its easier to buy one)
(any way, I've used two types in this instructable for two different switches. A touch switch and a normal dimmer switch)
5. duct tape
7. Screwdriver. (better to be an electrical tester)
