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.

  1. Ha, ha, ha! His name is Peter Rauch?! Rauch means smoke in German. Nice idea!

  2. a version with a much more reasonable BOM over at the Weber forums.

    early pictures of mine on page 3. parts list includes: arduino, busted hairdryer, chinese takeout container, $1.50 used LCD =)

    Peter looks like he might have been smokin’ more than just a brisket…! ;)

  3. 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.
