Smart Drink Coasters Tell Bartenders When to Refill
Sentilla is a company that specializes in pervasive computing, which means it would like to find a way to make anything and everything smarter by attaching a computer to it... Apparently, even coasters are no exception. The folks at Sentilla boast that they have invented the world's first Smart Drink Coasters, which know when a drink has been placed or removed from them and provide "visual feedback" (i.e., flashing lights) to notify the barkeep that your drink is dangerously close to empty. The coasters can even communicate wirelessly to work the lights in tandem and bring back old school favorites like Simon – as a drinking game, of course.
These three-inch squared gems are made using glass "picture frame" coasters from arts and crafts barn Michael's. Add some switches, rechargeable batteries and a tiny Sentilla computer, and you've got one of your own. Follow the directions from the Sentilla Web site and you will have coasters that will entertain everyone from the 'Girls Gone Wild' cast to the grandparents who'll have a hot toddy.
