Alcohol-detecting party horn offers safer New Year's celebrations

Now that we've successfully survived the Mayan apocalypse, it's time to start planning for 2013, which begins by celebrating New Year's Eve. One clever tinkerer has come with a way to ring in the new year safely with a party horn that actually monitors how drunk you are.

The Buzzed Buzzer looks like a normal party horn that anyone would use to sound off at a New Year's party, but this horn only works if you have reached a certain level of inebriation. While at first such a mechanism might seem like an encouragement to drink, it also serves as an ingenious way to check the sobriety of revelers who might otherwise refuse to submit to a breathalyzer before stumbling off and attempting to drive home.

The modified horn uses an Arduino microcontroller, a standard party horn, an alcohol sensor, a bit of code, and several other components, all powered by a tiny LiPo battery. It's not nearly as precise as a breathalyzer, of course, but it's still a nice tool to help enforce the safety of party guests who may need a little extra proof that they're not ready to get behind the wheel. The device's creators, Tyler DeAngelo and Sacha De'Angeli, offer detailed instructions on how to create your own Buzzed Buzzer on their website, and you can see it in action in the video below.
