Talking Breathalyzer Speaks Its Mind

No Thanksgiving dinner is complete without a good wine, Christmas isn’t the same without eggnog, and who could give up the bubbly on New Year’s? Along with your drink, you can now enjoy a breathalyzer that tells you just how drunk you are (sometimes rudely). As it does not measure blood alcohol content, it can’t be used to say whether you are legally able to drive (which, if you are drinking, you shouldn’t do anyway).
The Talking Breathalyzer, and it can be built from a kit or ordered for $139. It’s an Arduino-based circuit board connected to a commercially available alcohol sensor, which heats the gases you breathe out, and the alcohol with them. A chemical reaction alters the electrical potential of a circuit to show how much alcohol is present.
The unit comes with different voices – a pirate, an old Englishman and a New York cabbie are among them (the latter is not child-appropriate). It can also be programmed with your own voices or mp3 files of music. The LCD screen text can be modified also, and if you tether it to a PC you can have it tweet your drunken status (though that might not be a good idea). A demonstration can be seen here on the site of the device's creator, Al Linke.
