Matthew Arbsfeld documented the build of a sous vide cooker for a final class project. Sous vide is a type of cooking that uses a water bath with precise temperature control to cook food to an exact temperature. Matthew’s build is very well documented and shows how he designed and built the control circuit board that uses an ATmega processor, DS18B20 temperature sensor, and solid state relay with immersion heaters to measure and control the water bath temperature. He even added a bluetooth low energy board to allow control and monitoring from a phone. All of the electronics were put inside a custom 3D printed enclosure that looks great. Nice work!
