The Fourth of July is rapidly approaching and you know what that means? Fireworks and celebratory drinking! What better way to geek up your drinking than with the DrinkShield. The DrinkShield, available in the Maker Shed, is an open source breathalyzer kit that is used with an Arduino. The sensor reacts to alcohol content in your breath and can be programmed to light the attached LEDs to act as a standalone breathalyzer or hooked up to a computer for a more interactive experience. The DrinkShield is intended for fun use only and should in no way be trusted for anything important (like finding out if you are too drunk to make your own fireworks, juggle flaming tennis balls, etc.)
