I found this really funny project by Matt Mechtley where he hacked a breathalyzer and hooked it up with an Arduino-board in order to make a “drunk control” to the classic game Pong. The more you drink the bigger your racket becomes to make the game more balanced when under the influence of alcohol.
Before the game begins the players has to blow into the breathalyzer as illustrated below.
As one now can see, player one’s racket has now become bigger thanks to his intoxication.
I found this project very intresting and funny because it combines hacking an existing product to use it for another purpose and i think the result is really cleaver and funny.
