The DrinkShield is not quite as dirty as the picture above may convey. Circuitry nerd Craig Smith (who also happens to love drinking) has developed a breathalyzer that can be turned into a potentially naughty party game.
"The GfxHax DrinkShields are easy to build and a great tool to learn and get better at soldering. The boards are silk screened so that every part is marked on the board to easily identify what part goes where. If you have built electronic kits before you shouldn't need a tutorial to assemble this kit."
