I'm thinking of building something similar but instead of connecting the heating elements directly install a normal wall outlet and use a longer cable for the temp probe.

This way it would be possible to use a rice cooker as some have used in different projects or you can always plug in the same heating elements you used in your setup.

Do you think this would be feasible?

You pretty much describe exactly what I built. It's all installed in a wooden box I created that sits on my counter, the top has the PID display, on either side is a wall outlet, one controlled by the PID and one direct 120V current for the water pump. The temperature controller is on a long wire that just comes out of a whole I drilled on the front, though you can build the fancy headphone attachment as detailed in the link. All the other wiring is in the box too, including the relay which is nice since it muffles the sound of the relay switching on/off.

I tried using it with the rice cooker I had and the results weren't great. I found the temperature fluctuations too erratic but didn't really investigate too much since my rice cooker was gonna be too small for anything but eggs.

Nice! I'd love to hear about what you used for heating elements ( are you the same person who wrote that article? ) and as cooking vessel?
