I will either use a rice cooker or a slow cooker, which needs to be modified in order to keep the temperature. To achieve that, I use a microcontroller (Arduino) and a TRIAC based switch to turn the rice cooker (or whatever) on and off using a PID controller.
Essentially it all boils down to choosing the right ingredients. You need a good PID library, a versatile Arduino which is small enough to fit onto a PCB provided by tinkerlog.com and some electronics skills. I already made some prototypes on a bread board and I am currently designing a PCB board, which is not ready yet, but should somehow work.
BTW, I never can make up my mind which blogging system I like more: this one here, which is driven by blogger or posterous where you can have a look at http://justjoheinz.posterous.com
