First test driving a stepper motor from an old floppy with an arduino card+ld93d to get some random rythmic patterns. Sounds louder if the stepper reaches the end and hits against the metal frame, as in the video. A homemade piezo transducer was used to record it,but the audio of this video comes just from the mobile mic. Unfortunately the range of pitches is rather limited, but it's cool anyway! Couldn´t stop laughting at it the whole time, sorry for the out of focus recording :(
