[Al] at Open Gadgets just put the finishing touches on his
http://vimeo.com/31893552. It’s the perfect thing to install on ex-girlfriends’ phones to prevent 2 a.m. drunk dialing.
The project started off as a talking breathalyzer (http://talkingbreathalyzer.com/) connected to a computer that tweeted your BAC, gave weather and stock readouts, and functioned as a photo booth. Since the first reveal of his project, [Al] moved from the desktop world to the mobile domain.
The breathalyzer itself is contained entirely in an Altoids tin. The build is based on theIOIO (http://hackaday.com/2011/04/07/a-breakout-board-for-your-android-phone/) board that recently got support for Bluetooth (http://hackaday.com/2011/10/29/bluetooth-for-android-open-accessories/). An alcohol sensor in the project measures the alcohol content of the surrounding atmosphere and reports this back to a phone over Bluetooth. There’s no word if the Android version of [Al]‘s breathalyzer has the Twitter and photo booth functions, they would be relatively easy to add.
While a wirelesss, tweeting breathalyzer lends itself to a competition for a high score, [Al]‘s project could have a few very good implantation; a DIY auto ignition interlock would be a very useful device for some people. Check out the videos of [Al]‘s builds after the break.
