Build Your Own Wireless Beer Pitcher Monitoring System

Willy K. writes "Technology comes to the rescue when disaster strikes and your pitcher runneth dry. These Cornell students have rigged up beer pitchers that wirelessly advertise to the central serving station when they are empty, prompting alert wait staff to bring another round." Add a few steins and you're all set.

  1. I see an FCC problem here.. by the_rajah · · Score: 5, Informative

    From their web page: "The FCC sets aside frequencies between 420 MHz and 450 MHz for Amateur use, thus we are complying with the standard by transmitting our signal at 433MHz." IAHRO (I'm a ham radio operator - for 46 years.) It is fine to transmit on 433 MHz IF they have an FCC license and the transmitter identifies it's call sign at the proper interval. Otherwise, it's not legal.

    Amateur radio does not mean unlicensed. Getting a license is very easy. Check with your local ham radio club for details or visit http://www.arrl.org/
