    Air-core motor demo...

    I did a bit of an experiment last night driving an air-core motor with an Arduino and an L293 H-bridge chip.

    http://www.youtube.com/watch?v=ut9GZJTI3iA

    The video description has a link to the code I used as well as a connection diagram.

    You can find air-core motors in most car instrument clusters at junk yards. They're great because any single needle instrument is a great candidate for this.

    Thanks Mike. I plan on a better one once I've got fewer balls in the air at once.
