It's been a mystery for ages, but at long last, it seems a simple DIYer has found a solution. We all know that the best beers are the ones brewed at home, but after a given amount of "test sips," things can easily get a little out of control. In order to simplify the homebrewing process, the brilliant BrewTroller was concocted during a short stint with sobriety. In essence, the system utilizes a Sanguino microcontroller platform which was inspired by the tried-and-true Arduino in order to give brewers complete control over temperature and the like. When connected to a simple menu-driven display, it removes the need to bang out a paragraph of code while tipsy in order to tweak the flavor ever so slightly.
