Brewing Beer with MSP430

One of my hobbies is brewing beer, check out how one engineer made a simple control system to automate some of the process:

A MSP430 Double-Kettle Electronic Brewing System

Dave brews beer at home on a stove, but waiting and standing for water to boil takes most time and fun out of it. He came up with an improved automated system with an electric brewing system. A MSP430 Launchpad commands solid state relays which control  5500W heating elements which significantly reduces boiling time to 15 minutes for 5 gallons.
