So you have trouble getting up in the dawn - here’s something that might help nudge you out of bed.

as an input to the interface board. The conclusion? An ear-clanging din that is guaranteed to wake up the entire neighborhood, where you’ll probably receive nasty stares from everyone the next duration you get out of the house.
