Title: I built this during Covid.  When I released it, some of the parts went out of stock or skyrocketed in price, no longer making this an economic DIY project.  Now that things are getting back to almost normal, I thought I&#x27;d share it here and request feedback.  This is a very niche project for people who like the same things I do:  saxophones, Rust, mechanical keyboards and the Raspberry Pi.
