Construction music

Attach these noisy heavy-duty demolition equipment to an Arduino based controller that speeds them up to play at changing frequencies corresponding to music.

So when the construction in the neighbors house begins you can enjoy it.

If we are already at it, attach your fan, fridge, dishwasher, vacuum cleaner, and every other electric appliance to slow speed changes close to their normal range of operation, to create satisfying bass sounds instead of just background noise.
