Stian made this awesome sous-vide temp. controller, which he calls the “SousVide-O-Mator”. Built around an ATMega328 with the Arduino bootloader, it uses a DS18B20 temp. probe to monitor the temp, a 20×4 LCD to communicate with the user, and a solid-state relay to switch the rice cooker on and off. It also features one of the neatest, cleanest stripboard layouts I’ve ever seen (style counts!). He writes:
My brand spanking new homemade Sous Vide controller (PID controller for cooking). By connecting the relay to my rice cooker and putting the probe and a small aquarium pump inside I’m able to very accurately control the water temperature..
This is basically a heating immersion circulator as used by some fancy restaurants – readily made equipment cost in the range of $1000.. So I made one myself on the cheap (controller + rice cooker + water pump). This can be used to cook meat to perfection 🙂
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
Shoutouts for these people but not your friendly open source neighbors? :'(
@abe – john is one our blogger here, he didn’t know we were talking to you in the forums about your kit. we had a post planed about your kit later this week but john posted this first, we don’t coordinate post topics – the authors are free to write what they want and when 🙂
we’ll put up a post with your kit later today.
I’ve no idea how you found this, but thanks a lot for the plug, only made a quick video to demo for a few friends 🙂
The project isn’t done yet, I was planning to blog about it and document it properly after putting it inside a nice enclosure. Probably going for a case with a metal plate (backside) for the SSR – my rice cooker is however very low wattage – only pulling 3.5A/220v – I’ve never even felt the relay become lukewarm when running at full effect for a long period. I will remember to warn others about it though when I document the build later on, so thank you for the heads up Abe 🙂
@Stian: I used my maker/blogger-fu to find your project, but posting on Vimeo with appropriate tags (as you did) helps a lot! 🙂
Drop a note in the comments here when you’ve finished your documentation and I’ll do an update!
Nice to see all the sous-vide kits. I made a $60 open hardware kit for chest freezer conversions, sous-vide and many types of fermentations. I’m making yogurt and cheese right now!
