Build Your Own Wireless Beer Pitcher Monitoring System
Willy K. writes "Technology comes to the rescue when disaster strikes and your pitcher runneth dry.

This is probably the most useful "college student" invention post I have seen on the front page of Slashdot in a long time. As a former bar manager this would be something I would purchase with very few refinements. If this ever goes past the "gee thats neat stage" and becomes a real product it could be a must have for numberous establishments.
