There is nothing worse than having noisy neighbors and this guy sought revenge against his noisy neighbors by building an Arduino system that blasts loud music back at them automatically.
The system uses a microphone to detect when the neighbors play loud music and responds by triggering a CD player to blast short increments of Who Let the Dogs Out?
The system periodically stops playing music to listen for whether or not the neighbors have ceased playing their loud music. If they don’t stop, the system blasts them with another dose of The Baha Men. This is the sweetest revenge on such inconsiderate neighbors.
You might need some technical skills to build a rig like this but one can try and spread the movement.
