The Imperial March on Floppy Disc


(YouTube link)

OK, I don’t know how it’s done and I can’t find any technical information behind it, but apparently you can play music on a floppy disc with a stepper motor. I found a link to this post in the comments at VideoSift that might makes some sense to those who have more expertise than I do. -via VideoSift

Darth Vader lives! And he's in floppy disc format! This is what i love about sites like these. You log on every day and find the coolest, weirdest stuff you can't find anywhere else.

They just software "twiddle" the step/dir lines on the floppy controller with software, with pulses equating the frequency they need, but they cannot get to high a frequency.

In the scanner, its stepper motor is directly driven by the micro (with a driver IC of course), and can directly pout any frequency it wants on the motor.
