What do you use to cook sous vide at home? Do you have an actual appliance? Or do you use one of the "improvised hacks" I've seen on blogs, etc. ("improvised hacks" is not meant to be derogatory, by the way -- just couldn't think of how else to describe them)
I use the Sansair device - it seems pretty solid and is very easy to use. I'm not sure how much I'd trust a hack I would do that involves water and electricity, but others who work with hardware more I think would have no problem. The device is incredibly dumb, it's really just a circulator, heating element, and a decent voltage regulator with a thermometer and some basic logic gates to raise or lower the voltage when the temperature is closer or further away from the target.
