A Tour of my Brew System
This is a tour of my brew system. My system is cobbled together with parts from eBay, Amazon, Sparkfun, Auber Instruments, and probably Micro Center Mall too. The hot liquor tun is controlled by a PID controlling a solid-state relay that controls the tun’s heating element. The boil kettle controller is similar except instead of a PID I have an Arduino Micro that outputs a pulse width modulation signal (basically on for a period of time, then off for a period of time) to a solid-state relay that controls the boil kettle heating element. The Arduino also reads the rotary encoder and sets the numbers… and yes, it goes up to 11!
