I still haven't milled the blocks, but everything has arrived now, other than a few odds and ends. I am now mostly done with the control panel- only have a few holes to put in for the power, RTD, mounting hardware, ventilation fan and the switchcraft power connectors that I will use to connect the controller to the cooling units. Still have to get those things milled, however. I will include a few pictures.





The whole thing is 8x4x14".

Klaus

Looks good. I'm going more ghetto as a proof of concept. I've got the ATX power supply hacked and the CPU cooling fans. Waiting on the TECs & aluminum.

Looks good! I have the 15 gallon fermenter. Will be we curious to see if 2 peltiers will be enough to crash cool. Aluminum just came in.

Can you post the link to where you bought the aluminum enclosure from? I just spent an hour or so searching for one that is greater than 10X5X3 and couldn't find anything. The DC power supply I will be getting is 11X5X2.5 so the box you used should be perfect for it since my controller will be in another box and I just need one for the DC power supply.

Thanks

I bought it off ebay, from a seller named gkphotonics. His ebay store doesn't seem to list all that he has, so you can also go to http://gkphotonics.com/gk8.html which is his web page linking to the box I bought. I will say that the interior of the box has lots of grooves and ridges, and I ended up milling a bunch of that away. The link to the closest box to it on ebay is http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_569wt_1037

I bought an endmill and xy table for my drill press to do some very light duty milling for a different project, but it has come in handy for this, as the ridges have gotten in the way. Milling them away has made it much better for my purposes.

I'd make sure you check the temp at a couple levels in the conical while crash cooling. Without fermentation convection, stratification is significant. When I was using the brewhemoth internal chiller, the temps at the bottom were more than 10degF lower than the top. No joke. Cold beer literally flows off the coil and pools up in the bottom.

I am having zero luck finding someone to mill my blanks. Three places I talked to either can't do it or wont do it. The fourth wants $500.
