For a while now, my friends and I have been brewing beer at my house. I was inspired by an old Sparkfun tutorial about a bubble logger for Nate’s terrible wine. I figured that while logging bubbles is interesting and all, wouldn’t it be more useful to have real-time information on the fermentation process? I basically copied the optical gate method of counting bubbles, added a sensitive pressure sensor, and an AVR development board (Yes, Arwen, that’s your old TekBots board! ).
