You’re throwing a party for the Game Developers Conference and you think it would be cool to have a custom game. What’s the natural response? How about Pong that adapts its difficulty based on how drunk you are!

Matt hacked a breathalyzer by reading the pinouts to the seven-segment LCD with an Arduino board. The Pong paddle gets bigger if you’re more drunk. It was up and running for the 9bit indie games party last night at the GDC. – Link.

    As more alcohol is blown at the sensor it accumulate the alcohol, and the readings will continue to become very non-linear and meaningless until it has time to evaporate. Try it in the cold, you can be dead-drunk and the unit won’t hardly register anything as the alcohol in your breath condenses everywhere but on the sensor. Looks like fun though.
