This is like wiring up electrical boxes in your house. The building codes used in wiring electrical boxes, which includes the types of wires, the boxes, and how the wires are connected, are there to prevent fires. The wiring methods and ground connections are designed to prevent shorts, and the box is designed to contain the heat/spark if one does occur.

Product design has a similar set of requirements in order to get UL or CSA approval. I highly recommend that those who question their abilities or knowledge of wiring either buy a plug and play unit or get help in building one of these. It's tempting, I know, to save a buck but house currents and voltages have caused homes to burn down.

Amen to that. I am not advocating Tupperware enclosures. In fact, I have done belt and suspenders safety on my stuff (fuses, GFCI, waterproof enclosures, outdoor rated switches, etc.) and still work with a lot of caution.

Just do what you think is right, and if you don't know, ask someone who does. Advice found here, and elsewhere on the internet, is often very valuable, but sometimes misguided and/or dangerous.

Here is mine thanks to the great info in this thread. I am running two controllers, one for the cold side that my kegs are in and the other is for the warmer side for fermenting lagers etc... It's fairly simplistic in that it's two controllers, two outlets, and a big project box from Radio Hack. Here are some pics....

my controller died last week while i was on vacation, i don't know how many days it was down. the mead and cider is prolly all right, but the cheese, yeast and milk in the freezer is probably compost.
everything looks okay, display is on, but no power out to the plug.
i'll troubleshoot it tomorrow.

It looks really good!

just FYI, you have your receptacles wired incorrectly. The wire is not supposed to go around the screw, but rather go in the hole and then tighten the screw.

That's not true; you can either push it in the hole (screw need not be tightened) or wrap around terminal like he did. I've done both when I have multiple wires coming into one recepticle. He's fine.

Note: Some recepticles do have a plate that squeezes the wire when the screw is tightened, but most just push in the hole and stay.

some do have the option of sticking the wire in (lazy electrician option), but i think that particular design does require that the screw be tightened.

Yeah it looks that way. Either way he is fine. He has good secure contact.

The holes are only good for solid(non-stranded) wire.

wrapping stranded wire around a screw and tightening it does not make a good secure contact.

If you can pull on the wire & it doesn't move than I'd say it's just fine. It is in a sealed box after all, as long as there is some strain relief provided for the cords everything will be just peachy.

Keep in mind, this isn't a UL Listed appliance. We're just a bunch of folks making beer with inventive, DIY equipment in our garages.
