I went with a 6X6X4 utility box from Lowes. I wanted some airspace because the little unit got pretty warm while i was testing it.

I wired mine to power two separate outlets. one on the hot cycle and one on the cold. I have two PC fans on an old cell phone charger that i plugged in as well as the A/C unit.

I also grabbed a mono audio headphone plug and jack from radio shack. wired the probe up with those so i can remove it if necessary.

I like the ideas of a removable probe, might have to modify mine to have that!

Mine is removable too (as is many people's). I also had the idea of using a headphone jack, but it was less than ideal for something I'm planning, and I got such a great deal on 3-pin XLR components, that I ended up going with that instead.

Also, I'm kind of OCD about these kinds of things, so literally *everything* is removable on mine, allowing it to be stored as literally just a cordless box if I want.

I am building one of these either this week or next, so I for one appreciate the updates and photos before I get started.

Could you explain a little bit more about the headphone jack setup and wiring, and also the reasoning behind it? What are the advantages to a removable probe? Also, for those without collars on their units, is the probe wire just going through the back of the door near where the hinges are? Does it effect the seal at all?

Since someone wanted a source cited-
From 2002, but reflects the basic behavior of switching PSUs.
Most likely "fixed cost" current needed to support higher wattages is the main reason for the sharp decline below ~20%.

the headphone jack allows me to

1) replace the probe easily if it goes bad
2) have the unit be portable
3) allow the probe to be fed through the back of the Ferment chamber rather then the door etc.

Basically i don't want to crack the box back open again if i don't have to

So I have wired up my build, just waiting on the temp controller at this time. Attached is the wiring schematic. Please review, make sure it looks okay please. I am positive it is correct, and it is a hack of a few different diagrams and schematics. The tab between the Heat/Aux side is broken, the wire nuts were replaced by a terminal block to the hot and neutral wires, and the colored circles are the lamps.

Let me know what you think, and when the temp controller is here, will post pics of the final build.

Thanks,
Ryan

All this bitching and crying about how much power is consumed by this power supply or that power supply..
Does it really ****ing matter when your wife and kids won't turn a damn light off?

Haha, could not agree more... My kid is too young to turn the lights on, let alone off. But the wife... she is bad enough for the both of them...

Just assembled one of these into a 6"x4"x2" Radio Shack project box. It was a tight fit, but I was able to cram everything in there. The hardest (read: time consuming) part was cutting all the holes with my Dremel. I used barrier strips (also from Radio Shack) instead of wire nuts. This was a bad idea. It is really hard to cram multiple 14 gauge wires under one screw. The next one I build (need one for the fermentation chamber) will either use wire nuts or maybe solder joints.

I used a barrier strip from lowes, and it fit 2 wires under the screw pretty nicely. Cleaned everything up real nice in the box too. Need the damn controller, and i will be set. That was with 14 gauge solid copper wire.
