Brian Wang of Cornell’s ECE 476 class built this digital saxophone. The player blows into a cone that’s fitted with a microphone. The microphone is sent through an opamp and then a Atmel644 microcontroller. The user controls pitch with buttons mounted in the same arrangement as saxophone keys, outputting digital notes.
