THis trainwreck of a mess is the guts of the project, and there's a day or two worth of 3d printing, several days worth of modeling in TInkerCAD, and a couple days of programming the Adafruit RP2040 "Scorpio" feather to do my bidding across both the LED output channel and the i2c bus. The breadboarded LEDs got installed in a 3d printed 'puck' that is strapped to the backsize of the bottom Netapp bezel.
