Default Want to get into automation

So i am looking to get into automation of my homebrew. possibly a herms system. Im looking to be able to automate my system to get consistant results of beers everytime. The downsid is I'm strapped for cash. I keep reading boards on ssr, pid, audrino boards, programing, and such but I lost touch with the computer programing after I left high school about 10 years ago. Most of what I read on the boards seems like a foriegn language. (cause it kind of is!)

Currently I use a Cooler Style MLT and a seperate vessel for each my HLT and Boil Kettle. I was thinking of purchasing a March Pump and doing manual HERMS system but if there is a cheap way of automating it that would be great.

I would appriciate any help anyone could offer including pics of systems and how they work in Lehman's terms. I am very good with constructions, and DIY just don't understand a lot of programing and micro electronics.

What I would like to do is run an aditional vessle of boiling water that could be cycled on and off automaticly to maintain mash temps, and a way to then pump water to different areas based on a pump and switch system with disconects. If you have any ideas at all of what I would need and how much Im looking to invest that would be great.

As with any other hobby this would be a work in progress that I guess will start with a copper coil and a pump, but where do I go from there?

programming and micro-electronic skills are not required for an automated build. It's simply hooking up a few wires to make it turn out... There are plenty of builds on this site that meet your description, just dig through the DIY or electric brewing sections...

With the Johnson, you will probably overshoot your temps and have more fluctuation. The PID learns the system and accounts for when it's approaching temp to stop the output so you don't overshoot(as much). If you go with an element, do you mean getting a RIMS tube, or will you be adding an element to your HLT/HEX?

I know this is discussed slot but u am afraid of scorching wort with a rims sys. So I was thinking herms. But now I'm thinking it might be cheaper to jst go with the rims sys. Then I won't need another vessel right? Just a pid/ssr and a chamber (High temp PVC?) And a heat element?

i agree, you will want some integral term in your control loop. An On/Off control strategy isn't good for this application.

Look up rims for dummies you'll get all the info you need for a rims setup, you want to use SS and not PVC.

You won't need another vessel, but that cost isn't reduced as you need to use SS not hi-temp PVC for the chamber. You really don't have to worry about scorching. Just make sure the pump is running while the element is on and you won't have an issue. Rims you are looking at:

PID - $50
Temp Probe - $25
SSR - $15-$25
RIMS Tube - $75/$120 (built/bought)
Element - $15

Along with the pump, control panel, and connections.

I wish I knew where all the billchit came from about scortching wort with a RIMS brewery? It is just that....Bullchit! If a RIMS brewery is implemented properly there is zero possibility of wort scortching. There must be hundreds and hundreds of RIMS brewers on this forum. They chose RIMS for a reason and I am sure they didn't choose RIMS breweries because they like the taste of burned beer. CodeRage proved through experimentation that you really have to try purposely to scortch wort with a RIMS and even then it is not so easy. Jeeesh.........Get the facts people.
