The ECE 4760 Final Projects are here! Check out this DIY Digital Saxophone that was designed by Brian Wang. His design uses an omni directional microphone that is mounted in a tube to reduce background noise. The player blows into the tube and the microphone pics up the wind noise to know when the player is blowing. This signal is amplified and fed into a microcontroller. Buttons are positioned on the body just like a real Saxophone has and while the player is blowing pressing different key combinations allows for different notes to be played.
