Anybody ever build this? http://conical-fermenter.com/wp-cont...p-download.pdf Looks interesting but not sure I want to tackle it.

Wow- Great find! If you happen to build this, please let us know how it works. I have one of those fermentors and have been putting off buying a refrigerator for temp control due to space constraints... this would have a much smaller footprint.

I'd just like to point out that the author of that manual is none other than Ron Swanson.

Got all the parts...just waiting until beer's out of the conical. Will post pic's of the build. One thing I've learned already...don't put power to a Peltier cooler to test it unless the hot side is on a heat sink. New one on order.

OK, other than the charactor on "Parks and Rec" who's Ron Swanson?

I am always looking for new projects. Bought a bunch of stuff for this yesterday. Are you planning on putting thermal grease between the cold plates and the fermentor? I will use it only for chilling, however, and will control it with a programmable auber PID that I have lying around. I do wish the author of the instructions would post some result to see how well it works. For me it is about space. A very nice display fridge was on craigslist yesterday for only about 400 dollars, which is an ideal fermentor, but I just don't have any space for it.

Yep, Gonna use thermal grease on both sides of the Peltier. Encountered another problem due to poor planning (mine)... my aluminum heat sinks are 4 inches wide and the screw holes on the computer fans I got are 4 inches apart...oops. Thinking of epoxying on "ears" for the screws to go into. Good luck on your project.

I am still designing at this time, but my plan is to include a switch to reverse the polarity to the peltier coolers so I can switch it to heating mode, as well. This would be a simple switch controlling a DPDT contractor for the actual polarity reversal, and the PID would have to be switched from heating mode to cooling mode. I am doing this because I have a programable ramp and soak step PID that will allow me to do more complex automatic temperature profiles for fermentation. The whole project will be housed in an aluminum project box that will bolt onto the upright of the frame. Here is a diagram. Won't even get all the stuff needed for several weeks, then it will take me a long time to string it all together.
