Raspberry Pi, a $25 hackable credit card sized computer, is taking leaps in development and is becoming a hot bed for experimentation. Earlier, we had seen people using Raspberry Pi for different innovations such as shooting photos from space or for controlling home equipment, but this time, a hacker has used a Raspberry Pi to make a perfect beer brewing controller.
A few small commercial breweries were already using Raspberry Pi for automation, but Elco (creator of BrewPi) has open sourced the code and has made it available for the community. The BrewPi website has detailed instructions that will allow you to set you your own cheap brewery at home.
The software is easy to use and allows you to control the temparature with a prescision of 0.1 degrees. You can control every aspect of brewing through a simple web browser interface. The software also displays graph that makes it easier for you to follow the whole process of Beer making visually.
You can visit the BrewPi website to support this project and learn how you can setup your own BrewPi at home.
