Those harddisks are a treasure of raw material for your projects. The following uses have been found:

* the head motor has strong magnets. Have fun with them or use them to fix something solidly to a metal surface. These magnets are used for:
** holding the poster in the [[LetterRack]] in place
** the [[OpenDuino]] board is only fixed with magnets to the wall (in fact to the metal doorframe)
** using on the magnetic board and metal lockers to fix various heavy duty items
Caution: those magnets can be awfully strong, the bigger and older the disk the more force is in the magnets. Don't get your fingers pinched. Also don't make the magnets snap together as they are made of ceramic and will beak. In fact they will kind of explode into pieces.

* the platters are nice and shiny
** Build a windchimes out of them

* rings between platters
** also cool on windchimes

* the head motor solenoid has between 8 and 20 meters of very thin isolated wire. This wire is used here:
** solenoid for [[OpenDuino]]'s badge reader
** wiring for the door and alarm status detectors
** strings of the windchimes

* if you don't rip everything apart you can use the head motor as galvo for a laser show

* a lot of screws

* ''your idea here''

-* the motor can be reused if you either keep the controlling board or build your own circuit to drive a 3-phase motor.
+* the disc motor is usually a nice brushless type
 * the base plate with motor is used as ball bearing of the rotating [[Cortana]] antenna
