Homebuilt meat smoker texts your phone when the meat is ready! – Gadget Freak Case #170: Smoking Permitted, but Bring a Roast

Peter Rauch used a proportional-integral-differential (PID) controller that modulates electrical power to a heating element to create a home-built electronic meat smoker. A touch-screen display let him manage the controller set point and control-loop parameters. A J-type thermocouple in the top of the smoker provides a voltage signal so the feedback loop can control the smoker’s temperature. A second sensor, which reads meat temperature, is used only for monitoring and alarms. A user can enter a desired meat temperature, and receive an alert via a text message when the temperature reaches a preset value. Additionally, when the temperature reaches this setpoint, the controller can ‘hold’ the meat at a preset temperature to avoid overcooking it until you can remove it.

    Geez, no credit to Alton Brown? Ok, he didn’t add the fancy electronics, but stop me if this sounds familiar:

    Give some credit where it’s due, dude.
