Researchers have come up with a Buzzed Buzzer. Although it sounds like any old party horn blown on New Year's Eve, it makes a sound only if you're drunk.
You need not be lamp-shade-on-the-head drunk, but alcohol must be present on the breath of the reveller who's blowing it, Discovery News reported.
Unfortunately, you have to buy the materials and put it together yourself.
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.
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.
