A recorder is a woodwind instrument, similar to a clarinet, played by channeling linearly compressed air into the head of the instrument, through a channel (A). It then travels to the major wind way (B) and exits against a hard edge (C), which creates sound. The sound can be manipulated into specific notes used in music by covering, uncovering, or half covering different combinations of the eight holes on the body of the recorder. Normally the air which flows through the recorder is generated by a player's breath and the holes covered by the fingers of the player. However for this project, the air will be supplied with a three gallon, 150 PSI pre-pressurized air compressor and the manipulation of the recorder's holes will be accomplished using seven pre-programmed push solenoids.
Because of circuitry limitations, having only 7 push solenoids, and mechanical limitations, not being able to alternate between half covering and completely covering any of the holes, the notes that the pneumatic recorder can produce are also limited.
It will be unable to play C4, C#4, D#4, F4, and C#6 and will also be restricted to a set of notes dependent on whether the back hole will be halfway or completely covered.
