On the subject of fluffiness, I'm almost finished with the latest step in my automated beer rig.
See, a project I once worked on in college was a weather instrument of sorts, which took all sorts of readings via a series of thermistors, and produced a bitstream that described the current atmospheric conditions. The original purpose of this machine is unimportant, but I'm adapting it so that a refrigerator in my garage can read this bitstream with a bit of firmware installed on an old Blackfin, and this board then controls the refrigerator conditions. Long story short, the refrigerator is controlled by the weather sensor outside to maintain optimal settings. I've also drilled three holes for keg taps (because the 'fridge can hold three), and I'm hoping to, at some point, control the carbonation of freshly brewed kegs with some sort of "injector" logic, driven by some sensors that can estimate the carbonation of each keg.
My mother wants one next Mother's day, I guess is the point.
