well, ive got this old motor out a hdd today, and i thought why not mak it into a fan or something cooler so i was wondering about the pins, ther are 4 of them... OOOO 1 23 4 2 and 3 seem to make it move, but i was wondering what the other ones did, or in fact if they are bad ones to make it move on also what kind of voltage it needs, 12 or 5? thanks!
This guy might have some tips (read the whole thing, he mentions which connectors on his HDD worked the best to rotate the motor) http://www.afrotechmods.com/cheap/hdspeakers/hdspeakers.htm
