Citizen over at the 430h forum has been working on a smart coaster project that blinks and buzzes your drink status:

He’s trying to cram the following features into his design.

  • TI TMP006 for contactless temperature sensing.
  • Self powered design.
  • TI BQ25504 for energy harvesting via tiny solar cells.
  • A tiny buzzer for audible notifications
  • A bi-color LED for visual indications
  • Capacitive buttons to set the desired temperature for cold and hot drinks.

Via 43oh.
