Here’s what became of one of the boards after a bit of soldering and programming: a countdown timer with visual indication of when the time’s up instead of an alarm (there’s a place for a piezo buzzer on the board tho, but I don’t have any at the moment). My wife wanted one so i made one :)
Blinking! The displays are Kingbright SA52-11SURKWA’s which were the brightest I could find. Sadly their availability isn’t too great.
