Now that Christmas is in the rear-view mirror, you're speeding towards one last holiday destination: New Year's Eve, typically one of the most besotted nights on the calendar.

Once you make that last exit towards Boozetown, here's a little party favor that'll remind you not to get behind the wheel after you've sung those last notes of "Auld Lang Syne."

Although the Buzzed Buzzer, created by Tyler DeAngelo and Sacha De'Angeli, sounds like any old party horn blown on New Year's Eve, it only makes a sound if you're drunk. Maybe not lamp-shade-on-the-head drunk, but alcohol must be present on the breath of the reveler who's blowing it.

Unfortunately, you have to buy the materials and put it together yourself. Think of it as your last craft project of 2012.

All you have to do is take a traditional party horn, add a micro-controller, an alcohol sensor, a resistor, a buzzer, a battery and a battery charger. Yeah, I know, it sounds a little more complicated than just Scotch-taping everything together. Fortunately, there are detailed instructions on how to make your own. Just a heads up, you're going to need your soldering iron, wire cutters, wire strippers, needle nosed pliers and a computer installed with Arduino IDE and Teensyduino. You might want to do this before you start in on the cocktails.

Another word to the wise: Buzzed Buzzer is not a breathalyzer device, so don't think it's going to give you your blood alcohol level and let you know if you should drive or not. Better just to throw your keys in a bowl, uncork the champagne, get out the lamp shades and blow your horn.

Bottoms up.
