Work in progress: Arduino powered Beer brewing machine

Well some of you already realized that every few months I am brewing beer by my own with my high school-mate Hannes. We’re changing our mixture every time because we want to test new sorts of beer and improve our own mixtures. While we were really surprised that even our first attempt was ‘drinkable’, our last one was even better.

Hannes used all his knowledge to build our own boiler which will be able to brew 30 L beer. While brewing beer it is important to stay at certain levels of temperature that we had to do manually in the past. In our boiler we attached temperature- & fluid-level sensors. Their data is being used by an Arduino to control the heating element which consumes up to 3.3k Watt (!) so we’re using a remote controlled electrical jack to control it.

Our prototype-interface has been implemented in Max/MSP which is used to send temperature & timing data to the Arduino, so that the brewing process can be run without an attached computer or any other interface. Sensor-data will be stored in a database for further analyses.

This project is still work in progress and we want to use our brewing machine (we call it ‘Reaktor’ …) in the end of September.
Below I attached one of my first Arduino-tests 😉

More infos soon & you can ask me for any further details 😉
