Overview of what project is:
The glass harp or glass harmonica has been around for hundreds of years, and has always relied on having as separate glass for each note and on tedious manual tuning. By incorporating the NI myRIO and some basic hardware we can create a singing wine glass that can play multiple notes with the same glass and can tune itself.
This project demonstrates the measurement, signal processing, and control capabilities of the NI myRIO.
