I'm in the planning stages of a new system (I've mentioned it in a couple of threads...two-vessel, no-sparge setup), and I am thinking that I would like to take a stab at automating my mash temps. It would be a recirculating mash with a PID and solenoid setup to fire the MLT burner when heat is needed, a la the Brutus setup. I'm trying to keep it super simple and budget-friendly, as I have zero technical ability when it comes to this sort of thing. I have read up on PID controllers and solenoids and understand the concept but not how they actually work, and I have a few practical questions about equipment needs and whatnot. I will have somebody with a lot more electronics DIY know-how helping me set it all up and wire controls, but I'm not 100% sure on what I need exactly. Holler at me if you use something similar and might be able to help out with a few questions. I've only had one kinda sparse response to a similar query over on HBT. Thanks.
