Interesting concept - anyone have any luck getting this to work with
something like the Logitech Harmony series of remotes?
I also noted in the schematic a HD44780, and particular reason you chose
a 16x2 versus one of the larger, and can it be used to display system
messages, or is it just for IRK itself to display messages?
