Conical Fermenter Chiller/Heater Build
 
Hey guys, thought I'd start up a thread showing my heater/chiller build for my conical fermenter. My plan is to use an Arduino Uno for all the control. I have an old water chiller I got from a scrap yard years ago that I will be using for the cold side. On the hot side I have an aquarium heater that will sit in the reservoir I made a while back for the chiller.

For the last week of so I have been playing around with the Ardunio board and made a pretty good controller circuit/program.

After that I moved everything to a prototype Arduino shield

Here's a quick shot of the chiller in it's current state,

You can see a small power supply stuffed into the left side of the chiller. This will be used for powering the Arduino and the relays. On the right is the reservoir i made out of copper.

Over the next few weeks I'll be working on this project and posting updates as I go. I can't wait to get this working!

Also here is a quick shot of my first attempts at the webpage that will show status and have control of the fermenter.

nice! I would so do this with one of my spare NetDuino's if I could find a reasonably priced chiller.

Is your conical SS or plastic? how are you going to transfer temp to that? wrap the glycol lines around it if it is SS?

I've got a 14 g Blichmann, I'm still 50/50 if I will wrap it with a coil or make a stainless coil that will live inside the fermenter similar to the brewhemoth imersion chiller.

I think I spent 40 dollar on that chiller a while back. They had a pallet of them sitting on the lot. I walked away smiling :)

Nice.. I've been thinking about just putting a plate in my new Keezer build and just using a pump to circulate through to the fermentor. I mean heck I'll already be paying to chill the keezer :P

Small update today, working on the arduino code some more. It's still pretty rough at this point but I got it tweeting its status hourly!

Also I finished the ATX wiring harness that will be used to power all the low voltage gear. Now I'm waiting for UPS to deliver some more parts :(

Yep, subscribing to this. As a web designer and software techy, I have to see where this is going!

Subscribed. Where did you find the chiller?

+1,000,000 awesome project! I wish my beer would tweet me!
