The Breath Car by Matthew Brown is for beginner musicians just learning to handle horn instruments. It’s object is to help the beginner train their controlled breathing. The car is controlled by a mouthpiece. When the person blows hard it will steer to the right, and softer blowing will result in the car turning to the left. Much of the skill behind playing wind instruments requires good controlled breathing. The skills required for this gadget can significantly improve the controlled breathing, therefore improving musical abilities.

How does it work? The controller contains a MIDI breath controller which converts breath pressure to MIDI data. This is sent to MAX/MSP which converts MIDI to serial data. Serial data is sent via Bluetooth and PIC chip to a servo on the car which controls the steering. The forward and backward controls are hacked from a cheap toy car.
