$1.92 for a nifty LiPo battery monitor, uses 8 LEDs and loud beeper, indicates if any of 2-4 cells in a LiPo battery drop below 3.3V. It might also be wired up to 2-4 switches/pushbuttons (and appropriate voltage dividers) to indicate which button is pressed.
A $2 game show buzzer? A two-buck burglar alarm?
What would YOU do with it?
