If you are young or somehow didn't own a computer until 1999 (raises hand slowly and shamefully) you might not know that a stepper motor is one of the massive doohickeys needed to read and write floppy discs back on our ancient computers. You also might not know that they they were noisy as all hell. You also might not know that they can be programmed to make their noises in a musical way, and if you have three stepper motors and some time on your hands, you can make an eerily accurate version of most of the songs from the original Super Mario Bros. WELL, NOW YOU KNOW. (Via I Heart Chaos)
