    I recently disassembled 82 CD-ROMs because I need the head positioning
    mechanisms for a project.

    I'm wondering what, if anything, the leftover components in the heads
    might be used for.

    They have to be removed, so I surely won't wind up with the entire 82,
    and there are a variety of manufacturers and styles, but I could
    surely salvage a dozen identical ones without too much trouble and a
    larger number of quite similar ones.

    Any ideas for simple projects and/or uses for these things?
