Sous Vide

DIY Sous Vide Controller, version 1.5


It’s been a little while since I checked in, but I thought I’d give a quick update.  I’m hard at work getting production versions of my sous vide heating immersion circulators ready for sale.  The picture above is of my current prototype, based largely off of the DIY design I published a few months ago.  As you can see, I’ve got a custom-made heating coil and a slightly prettier enclosure.  The controller I’ve selected is also far more user-friendly, and I’ve upgraded other components after months of intense testing (and a handful of literal meltdowns). 

Anyhow, I’m still working as hard as I can to bring you all a sub-$200 sous vide heating immersion circulator accurate to .1C!  If you’d like to be on the email list when the first units are ready for sale, please leave a comment below.

I am very interested in getting one of you sous vide setups. Have you been able to sell any? I may be in the market for 3 or 4 as I evangelize the benefit of this cooking style to colleagues.

Would it be possible to let me know which PID controller you are using now, as well as how you upgrade your other components? I am interested in trying to build my own, but I’d like to know what the most effective components are. Thanks!

Definitely interested and thank you for all the work you have done so far.
At the under $200 price, think I’ll wait, let you make it, I don’t need to buy tools etc, I’m a cook, not a scientist…lol….

I’m interested…
Looks like it has been 2 years so far, but who knows maybe you will whip up a batch of these babies soon.

Hi Scott,

I’ve ordered all the parts to begin building my own unit using your plans. Do you have any updated advice to avoid repeating your meltdown problem? I told the chef that I work for about my plan and he said his friend had one of your units and it blew up! I am undeterred, but would appreciate a warning if there are particular pitfalls to avoid. Thank!
