Wow, I'm impressed! Making a guitar chord detector using Jetson Nano is such a cool project!
I checked out the demo video, and even though you said it's not HQ, I could still see the potential. And thanks for sharing the source code and model on GitHub; I'll take a look.
By the way, if you're into exploring more unique instruments, have you ever considered creating the same for the bodhran? It's an Irish drum that creates an amazing rhythm. I saw some bodhrans for sale recently, and it got me intrigued about trying one out.
