If you can stay sober long enough to build one, a company called Sentilla has developed a DIY "smart" beer coaster that could lead to a myriad of new drinking games for you and your friends to enjoy. The coaster is "smart" in the sense that it can detect when a drink is present and when it is removed, it can communicate with nearby coasters, and it can provide feedback in the form of flashing lights. Plus, it does it all wirelessly. More info and a video of the coasters in action are available after the break.

Besides its more obvious and pointless applications, Sentilla also suggests that these smart coasters can be used to notify a bartender when your are in need of a new drink. If you would like to try your hand at building one, instructions are available on the Sentilla website. -Sean Fallon
