[IronJungle] had an old hard drive taking up space in his workshop, so he took it apart and wrote in to remind us how useful (http://ijprojects.blogspot.com/2012/07/repurpose-old-disk-drive-as.html) these old pieces of hardware can be. Aside from offering up incredibly strong magnets and donut-shaped mirrors, HDDs also come with a reliable stepper motor in tow.

He pulled th eold drive apart, wiring up two of the stepper motor pins to a pair of the drive's header pins. This allowed him to easily access the signals produced by the stepper simply by hooking up a small JST connector to the back of the drive.

From there, he can use the drive for any number of purposes. For the sake of discussion, [IronJungle] used it to flash an LED as seen in the video below - something he willingly admits is no great feat. However, stepper motors can be used for in a wide array of projects, both simple and complex. Be sure to share your favorite use for salvaged HDD motors in the comments.
