Windbelt From Hard Drive Voice Coil and Magnets

This is a Proof of Concept version of Shawn Frayne's Windbelt built from hard drive parts. I knocked it out in a couple of minutes because I got tired of waiting for someone else to do it ;-)

This is a quick and dirty instructable.

Step 1: You Will Need ..

A hard drive
ribbon
wood
nail
magnet wire
led

Step 2: Salvage the Voice Coil and Magnets From a Hard Drive

We'll skip the disassembly step, it's simple enough.

Step 3: Assembly and Operation

Use a nail through the ball bearing in the voice coil to attach the coil to a piece of wood.

Mount the magnets around the coil just as they were in the HD.

Tie a long length of ribbon to the heads on the voice coil.

Solder a couple of pieces of magnet wire to the contacts of the voice coil.

Solder the other ends of the magnet wire to a LED.

To operate, hold the wind belt in front of a fan with one hand and dynamically tighten the belt with the other, to light the led takes a fairly low frequency ( And consequently high amplitude).

Future steps, frame, rectification
Enjoy!
