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.

definitely interested, though I’m ashamed that i couldn’t get mine working based on your previous post.

heck, I’d pay you $100 + shipping if I could send you mine to figure out what’s wrong with it.

I’d be interested, but can you enlighten me on what upgrades you made? I was planning to make my own, but in a metal enclosure.

Put me on the list. Found the blog recently while looking at the beer cooler sous vide stuff. Great blog, great fun, keep up the good work.

Please add me to the list.

I’m curious about floating packages, too. Could you perhaps post a video with the pump going and a typical package?


Do you plan a kit?

I expect it will not be UL listed (impractical for small numbers; it was a pain in the ’80s and expensive besides) so I personally would prefer a transparent case. I could *see* that nothing had melted. It would also make for a better conversation piece.

I find cutting the holes in the case the most daunting. I would likely butcher it. Plastic shop in middle school was 34 years ago. Acrylic and I did *not* get along.

Did you find a simple way to avoid burning out the heating coil if it’s turned on out of the water?

Please sign me up and let me know if you need a deposit on a unit to help with your int. cost. Thanks in advance

I’d definitely buy one, also I like the idea of this better than the sur la table sous vide supreme. Do you have a potential time frame that you are looking at to get this out to the public.

Hi – you do some really interesting stuff – I like the Olive oil dust – keep me up to date with what you do

Mark me down for one! I’ll even pay you up front it will help with production costs. I’m a chef in seattle as well. love your site!

Please add me to the list, very interested.

Have you thought of selling a “DIY Sous-Vide” kit? All you’d have to do is package all the parts and print up some instructions. You could market it to DIY sites, forums, etc.

Drooling already… Please add me to the list as well. And I’ll pre-pay you now if I can get my hands on the first batch.

Thank you for all your hard work.

What kind of container is that? is that a standard size bain marie pan? Is it similar in size to the plastic container you used in your first version? All the ones I found listed at hospitality wholesalers seemed to be too small.

Please add me to the lengthening list of folks who want one of these bad boys!

I, too, will be happy to pay a deposit, or even the entire cost, if it will help.

As an engineering electronics person, I love were this is going. Thank you for putting forth the effort on our behalf. I was just going to try this project on my own, however I will leave it to the professional.

I am interested. What is the ETA on these things? And, like the previous diy IC, will you be posting instructions on how to make this one yourself, or will you just sell them already made?

Hell yes I want one of those!!! I’m drooling already thinking of the things that I can do with one! Soft boiled Chang style eggs – oh my!!!

I am interested as well as my friends somehow don’t trust my electrical wiring. I built one using your 1st ed plans and after many months of sub-80C cooking, the orig aquarium pump died. Any advice for water circulation options?

Damn! I knew I should have kept up to date. After deciding I didn’t want to mess with rice cookers and PID controllers, I gave up, hoping to pick up a used sous-vide supreme someday. But you’ve made that dream a possibility now! You can definitely count me in. I’ll have giant beer coolers ready for a celebratory roast chicken party once I get my hands on one of these! I’ll be waiting with CC in hand.

Will you post plans for this one as well? Or at the least a parts list? You’re likely to have to sell it as a kit anyway.

Also, the red looks horrible. Go back to the clear.

Would love to hear an update, add my email to the list. I’m very interested in updated plans, kits, finished product – in that order. Would love the satisfaction of building one myself but I know some other people who would probably want to buy from you.

Also, I know you were having problems with the coils burning out if the unit is turned on while not submerged. Have you considered using a water sensor switch to prevent the unit from turning on when it’s not submerged? They’re pretty cheap.

I’ve been looking for something like this for a while. A budget sous vide controller that is my class books each semester. thank you, cruise

I’ve been looking for something like this for a while. A budget sous vide controller that is less than my class books per semester. thank you, cruise

I just had a steak last night that I am sure was prepaid using sous vide cooking method and it was the best I have ever tasted. Been thinking about trying to build my own also. I am defineately interested in your model

That looks awesome. You mentioned you were looking at making the thermometer and/or heating elements separate so that you could use it for regulating a smoker. What if you wired just a standard 110 volt outlet to the outside so you can plug the electric elements in and regulate with an extended probe?

Looks great! Was going to build my own, but I’m also definitely interested in taking advantage of your trial-and-error, and don’t mind paying for it.

Hi Scott
I found your site while trying to figure out what those wily Iron Chefs were doing with the vacuum sealed bags. I think your $75.00 version makes all kinds of sense over the $500.00 plus solutions out on the market at this time.
Boiling, (or nearly boiling water) should not have to cost that much.
I have two questions or comments though:
1.) Have you considered a beefier connection or clamping system? I picture your bent plastic and eye bolt a likely failure point. In fact I just don’t like the idea of the electronics sitting out over that water at all.
2.) Related to my previous point, I think I would prefer a unit that would sit next to the water container and had the outlets for powering heaters and plugging in a temperature sensor.
Those items regardless, please keep me informed as to your progress as I may wish to purchase.


i’m very interested.This is the best way to produce perfectly cooked meals.If you can do it cheaper than anyone else! I may just want more.please let me know.

I hope that you have considered adding a float switch to the design for safety reasons, especially after having seen meltdowns occur. They are <$10 on ebay in small quantities, made of stainless steel.
I was amazed at the rate of evaporation with the container uncovered, especially on a dry winter day.

Prettier enclosure? One of the most appealing things about the old enclosure was the look of the thing. I’m sure others may disagree. I’m interested in one, but doubt I can wait for long before I start building the one from your blog.

Made the $75 version and I’ve been using it a lot…
I would love to purchase a more robust version from you. Keep us informed!

Great Work!!
Please keep me appraised and let me know when the unit is available. I’d be happy with purchasing just the key components from you and sourcing the rest locally. Sooner rather than later and please don’t wait for the perfect light bulb. We may stay in the dark forever if you do.

Would love to be informed as to when this is available. Also looking to make the DIY model of the same. Lot’s of great information here overall, thanks Scott!

please keep me posted! i would like to take a stab at making the $75 version, but i don’t have the time currently.

Humm… apparently you’ve got a potential Fortune 5000 in your future… should you enter the production phase count me in for one as well (and let me know about the IPO too)

I’d be very interested if you could ship to europe.. I’m hoping you’re getting close to having it done! (found this looking for a way of building one, but will probably be unlikely really).

Hello Scott –

Would this unit be ready to go “out of the box” or would it be DYI or kit? Personally like the kit version if had a choice.

Thanks much.

Definitely keep me posted . . . built my first one as per your original post, still working great 4 months (20’ish uses) later


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!
