DIY sous vide question

[jbocker34]

Hi all,

I'm trying to figure out what I need for a DIY sous vide project, but using an existing rice cooker for heating. Looking at the popsci article, they suggest auberins for a "plug and play" version (http://www.auberins.com/index.php?main_ ... x&cPath=13) but it seems pretty expensive compared to what can be bought from lightobject. Am i missing something? the PID, the thermocouple and the relay are what seem to be needed when using a rice cooker or crock pot and that all seems to be within a $50 price range total (the only complete-project DIY instructions I've found are done by creating your own heat source/tub which I already have in a rice cooker!)
Anyone know what I'm talking about? Is there something else I'm missing?

thanks for the help...

You've covered it. The only important question is where to put the thermocouple, and in a small vessel like a crock-pot or rice cooker, it won't matter very much. I'm not familiar at all with how the pros do it, but I would perhaps put the t-couple in an unbreakable closed-end tube (stainless steel?) and seal the open end around the cable with silicone/RTV to waterproof it, then make sure the cable itself doesn't go in the water. Someone clever could probably make a hole through the cooking vessel's wall or bottom and seal the t-couple in it in such a way that there are no leaks, which would be even better...

clarification here - the ETC-PT100WP2M sold here is fully submersible, right?

Yes
