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)
Step 2: Disassembling the HDD
Read the first two lines again and then start by taking your hard disk apart. What you need from the hard disk is the platter. After you take the top HDD cover you will notice the Spindle. On the top of the Spindle are a couple of screws you must remove as well. Then you will be able to take the platters off.
In this instructable, i used two platters, one from a dead 80G WD HDD and another from a mummified 5M 1985 hard disk. It has a huge and beautiful platter.
Step 3: Preparing the platter.
Now what wire to solder to the platter?
The touch switch has a yellow wire which is a touch sensitive wire. Other wires are black, White, and Red. White and Black wires are the ones to reach the lights. Red and Black wires are connected to the power source. Yes the black wire is connected to both the lights and power source. Look at the schematic image of the touch switch for more elaboration.
Step 4: Manual Dimmer
I have uploaded a video illustrating the touch switch platter.
