Halloween Prop: Mario Bros. with full sound effects

Creativity abounds in putting together this pair of Super Mario Bros. costumes. [Rob] and his wife didn’t stop with a well-assembled troupe of familiar wardrobe items, but decided to go for authentic sound effects as well. It started by finding a few of his favorite Mario sounds on the Internet. From there he grabbed a greeting card that allows you to record several message. He recorded each of the sounds and removed the electronics from the card. From there an Arduino mini was connected to the playback buttons and to a Wii nunchuck. After the break you can see that when the kids press a button, the card plays back the sound of jumping, shooting fireballs, etc. So far it’s the best use of an audio greeting card that we think eclipses its intended use.

    If you read the post, you’d see that thats only a nunchuk and that its being used as an interface for an audio greeting-card arduino setup.

    They got a headstart on movember – no fair!

    I want to see sensors in the shoes that when both are off the ground, you get the jump audio.

    Nicely done!

    I was thinking about that too, except it might be easier to just use the accelerometer in the nunchuk if you keep it strapped to your body (otherwise gesturing would set it off).

    The Nunchuck has an accelerometer in it and when they jump it plays the jump sound.
