SuperMarioBrothers Theme playing on two DC Motors

at 3:00 pm. Filed under Electronic Hacks, Funny Hacks


Thanks to Joshua for sending in this familiar tune being played in a not so familiar way. A PIC18F4520 is connected to an H-Bridge and is pulse width modulating two brushless DC motors to create the Super Mario Brothers theme!

    Interesting, but your timing is off — some notes and pauses are way too short! And the song should be a data file, not a program, so you could play a different tune with a different file.

    I agree with LeftyX. Nicely done, but you might want to take a few tips from a someone who’s done this before. http://hackedgadgets.com/2009/06/24/super-mario-played-with-three-stepper-motors/

    Don’t think this is a brushless DC motor. Brushless DC motors require at least 3 wires. (For sensing the back EMF or it would have a dedicated hall-effect sensor to determine the motors position so that the proper waveform could be sent to move the motor.) The motors appear to be standard DC brushed motors. If they are indeed brush-less, any idea how they work, with only 2 wires?

    Those aren’t BLDC motors, that would need 3 wires. They’re just off the shelf Brushed Gearhead motors.

    But still I think it’s a nice idea. Ofcourse it could have been a bit better. Bit give the guy some slack :).
