Default 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?
