    Just finished assembling mine, and nearly everything works. My only problem is that LED4 (red on my assembly) is dim during normal operation. It does shine brightly when first powered on, but is barely visible after that - especially with the sound on. Any thoughts on what I can check?

    EDIT: I’ve fixed it. I’m not sure, but I think I had a hidden solder bridge between pins 31 (TXD, which I knew from prior Arduino experience goes high on boot) and 32, with another very tiny trace of a bridge between pins 1 and 2 (which control the buzzer). Used a hot air rework station to remove the atmega328, cleaned up the excess solder, and reflowed the uC back into place.

No public wish lists :(
