Gadget Freak Case #207: Android Breathalyzer in an Altoids Box

Al Linke's tiny breathalyzer is stored in an Altoid's box and the results can be sent to his Android phone. The key component is the IOIO board, which enables the Android to receive data from eternal sensors.

The innards of Al Linke's metal Altoids box won't keep your breath sweet, but it may keep drunks off the road. Al's Altoids box holds a tiny breathalyzer that may help partiers ascertain whether they've had too much to drink. The alcohol detector in the Altoids box can send the results to an Android phone.

The key component of this project is the IOIO board (pronounced "yoyo"), which enables an Android phone to receive data from external sensors -- the alcohol sensor, in the case of Al's breathalyzer.
