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 🙂
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
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!
