Default Jenky Fermentation Chamber help

Help!

Ok so I just tore apart the kids swingset because it was made out of wood that has started to rot away, however there is still quite enough there that got me thinking about building a modified, Son-Of-A-Fermentation chamber.

I use 2x Mr. Beer kegs, I was planning on building it with one on top of the other with separate shelves, and a small fan that stays on moving air between the two to keep it the same. The cooling chamber will remain the same on the back, pulling the air flow out of the top of the main chamber, making the air flow to the bottom where the ice it, before re-entering the main chamber through the top by a temperature controlled fan.

I have everything to make this happen except for the temperature switch. Is the STC-1000 the cheapest thing out there? I just need something that I don't care if it's digital or not to close a relay to turn the fan off if it ever gets higher than 62-65.

Also, will 1 fan circulating the air between the two halves be enough to keep it the same temperature and not make one hotter than the other?

Thanks

Sorry I needed to add this as well:

Mr. Beer's Kegs are 9" Wide, 9.5" Tall, and 13" Long. Each of the 2 keg chambers will be 12"x12"x18", which, when taking lumber thickness into account, makes for an overall dimension of 28.5" Tall, 15" Wide, and 31.5" Long. Will this be enough for circulation? The Ice chamber will be 6"x the height of the whole thing.

I didn't know how much room I needed around each fermenter.

Also, now I know this is REALLY jenky, but I planned originally on using the construction board foam and corrugated plastic to make the outsides, however I am wondering if aside from aesthetics cardboard on both the inside and outside of the frame would work ok when stuffed with Newspaper...

Like I have repeatedly said, Brewing on a budget ain't got **** on me

Would this thing work?

http://www.ebay.com/itm/Heat-Cool-Temp-Thermostat-Temperature-Control-Switch-Thermometer-20-90-C-DC12V-/350939172798?pt=LH_DefaultDomain_0&hash=item51b59a cfbe

There is a slightly more expensive version with a digital display.

Thanks

A few thoughts on your project as a owner/user of a Son-Of-Fermentation chamber. I think the foamboard is worth the money for water resistance and insulation they have cardboard and newspaper beat. But heck, if you have a free souce, it maybe worth a try. That device might work for your temperature control, but are the two chambers to be different temperatures or is the air flow enough to go from one chamber to the next and still work? I might have one sensor per chamber to be sure. Check out your home depot end caps, I got my thermostat for $8 and it is a very nice but discontinued model that uses battery power instead of the adapter you might need for that one. I think that constant air flow would deplete your ice bottles, possibly bring your temps below desirable and lose the control you are trying to gain by having this box.

ps. sorry it is poorly formatted, just off the cuff thoughts.

All good, I am going with the linked control and aome 1/2" foam from work doubled up. There is a fan constantly ccirculating air between the bottom and top chamber, the ice chamber fan only kicks on when the switch flips

Its getting there, its taking time and the foam off to the side is being weighted for glue
