Just thought I would add my temp controller build to the list. I was looking for something as small as possible yet still allow for an outlet. Digging around the local big orange home supply center, I found a plastic box that measures 4x4x2. So of to work I went cramming everything inside and here are my results.
And all closed up ready to be put to use:
I think the only change I would make is to place the controller about 1/8-3/16th of an inch lower in the box. As it is right now, the outlet pushes on the controller a bit, but too much. Ready to control the heating and cooling for my fermentation chamber year round! Time to brew up some Lager!
