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 🙂
Perfect for Sous Vide cooking! ( For more information about Sous Vide: en.wikipedia.org/wiki/Sous-vide )
