This project is a bit different from what I normally do. No firmware to write, just several trips to the hardware store and a lot of quality time with the drill, files, and nibbler. But this one has a higher purpose: Food.
It was actually a commission by a friend of mine. He wanted to try sous-vide cooking, but neither of us were crazy about the idea of paying for something lab-grade, and even the consumer-focused SousVide Supreme seemed kind of lame with its $450 price tag and no circulation pump.
The interwebs are brimming with do-it-yourself solutions for sous-vide cooking, ranging from the incredibly simple and cheap, through a middle-ground of modified rice cookers and crockpots up to other DIY immersion circulators like this project by Scott at Seattle Food Geek.

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.
