Wow, this looks like exactly what I'm looking for. Namely, the all-electric aspect of it. Can we get some plans and sources for parts? I've been looking at http://www.highgravitybrew.com
at their "Build Your Own Brewery" electric systems, but $1500 sounds a little much and it's not temp controled. They recommend adding a Johnson Control temp controler to it. It looks like yours is not only temp controled, but fully automated. I guess there are plenty of posts that discuss automation, but I have never seen any discussion on the electric portion of this. I WANT TO BE ABLE TO BREW INDOORS!!!
Sorry it took me a while to get back. I built it out of 1 1/4" 14 gauge steel tubing and some steel diamond plate. I thing materials for the cart itself with casters was under 100 bucks.
It isnt fully automated but it is set up to be eventually. I have a version of it built to scale in google sketchup. I went ahead and uploaded it to the sketchup warehouse, search for Brutus 20e and it should pop up.
I can post up some electrical drawings later when I get some time.
