Pictures of our Brewstand and BrewNinja buildout. Everything is obviously a work in progress.
Could your supply more information on your control panel
I’m going to put a post together eventually with some more details but basically we are using the GPIOs on the Raspberry Pi to actuate solid state relays using mosfet switches. The user interface is a Chalk Electronics display with capacitive touch. I have plans to redesign the relay circuit to make it less expensive using electromechanical relays. We are using Neutrik audio connectors for input power and temperature readings and for our pump and valve control outputs. I am using a doorbell transformer to provide the 24VAC needed to control our gas valves. Are you looking to do a similar build?
