Sous Vide Cooker

I was given a modernist cookbook that had sous vide recipes. They looked incredibly tasty, but I couldn't make them. One of the recipes was for fish, and only required a cooking temp of around 125 F, which actually isn't far off hot tap water temperatures. I ended up putting some raw fish in a ziploc bag, stuffing it in a thermos, and pouring slightly-more-heated-than-tap water into the thermos. I let it sit for half an hour and then finished it in a pan with butter and lemon pepper. I didn't get sick, and it's actually one of the best tasting dishes I've ever had in my life. I decided I wanted to be able to do this easier, for longer durations, and with more control.

I had an old crock pot that I wasn't using, and it turns out those are easily modifiable into a DIY sous vide setup with around $60-$80 worth of parts. The parts are as follows:

1. Old crock pot (that doesn't have warm settings/modern electronics)
2. Temperature probe
3. PID controller (proportional integral derivative)
4. Solid state relay
5. 18" or so of extension cord
6. GFCI outlet to help make sure everything doesn't burn to the ground

You also need miscellaneous connects, crimping tools, and wires. You also need to be comfortable splicing wires that will be connected to an outlet.

I'll get into more detail later. I'm currently mid-way through building the site, and just wanted enough here to help guide my design decisions and coding.
