Build Your Own Smart Drink Coasters
From Sentilla’s Blog:
The idea: let’s build drink coasters that are so smart, they know when a drink has been placed on them and whether it is full or empty. They can notify the bartender when you need a new drink, and even be used to play drinking games.
Read how the Sentilla folks have done it, using a product they call Tmote Mini and Java for the software side. The complete article can be found here.
