Who said that tech hardware has to be useful all the time? What’s wrong with having a bit of pointless fun with it? The Buzzed Buzzer contains an alcohol sensor and will only work if it detects booze on your breath. Use enough of these at a party to ensure that anyone that looks like they’re having fun, is actually having fun. Well… not that you can’t have fun without alcohol, but you get our drift. Using a $16 Teensy 2.0 Microcontroller, a $5 MQ-3 Alcohol Gas Sensor, and a handful of other easily obtainable supplies, the Buzzed Buzzer is a surefire way to have drunk peeps making noise, eager as drunk people often are to prove their drunkenness. Unfortunately, this is not a product you can purchase at a store; the link at the bottom will lead you to very detailed instructions on how to make your own.
