Making a Flute Controlled Mouse

Hi, thanks for posting this. I am the blog author and prepared the following as a Show HN blurb: Have you ever wondered how to improve human-flute-computer interaction, wonder no more: this project allows you to control a mouse cursor via sound.

The project is based on the Raspberry Pi Pico RP2040 chip and features an ANSI C fixed-point pitch estimation algorithm. Another implementation uses the Web Audio API. Join the flute-based mouse revolution today and experience H(F)CI like never before.
