My brand spanking new homemade Sous Vide controller (PID controller for cooking). By connecting the relay to my rice cooker and putting the probe and a small aquarium pump inside I'm able to very accurately control the water temperature..
This is basically a heating immersion circulator as used by some fancy restaurants - readily made equipment cost in the range of $1000.. So I made one myself on the cheap (controller + rice cooker + water pump). This can be used to cook meat to perfection :)
Perfect for Sous Vide cooking! ( For more information about Sous Vide: http://en.wikipedia.org/wiki/Sous-vide )
