While stumbling through the internet, I came across this site. An expensive setup but I found the tutorial entertaining and could be scaled down to reduce costs.
Top notch setup, most of the controllers that are discussed about and or built on this site were somewhere in its infancy a vision if the electric brewery's setup. It's awesome! Wiring my own as we speak
I cloned that bad boy with some slight modifications to the kettles, etc. but I used the control panel exactly as described. This is a great system and I highly recommend it.
My brew day is faster due to the electric system and I've found it to be more efficient and easier to control.
