What

Because smoked dead animals are at least as tasty as BBQed dead animals, we need to have a nice smoker. While the BigGreenEggBBQ can act as a smoker as well, it has a fairly limited capacity. Furhtermore, it can not be electrically operated, which makes temperature control more tricky.

So enter RevSmoker.

Design

The idea is to use a steel drum to build something like this but over 9000 times cooler, with electronics and blinkenlights.

The idea is that there is a electric hot plate/heater in the bottom of the drum, that heats a steel box full of wood chips, generating heat and smoke. A micro controller measures the temperature, and drives the hot plate in order to reach a set temperature, that can bet adjusted using a dial. The target and current temperature are displayed on a LCD display. There is a tray at the bottom of the barrel, allowing the heater/wood box to be can be easily removed for refilling, without removing the smolked items.

Design inspiration :

• Trashcan smoker
• Ugly Drum Smoker
• Alternative, 2 chamber design

Mechanical and electrical parts

• steel drum that used to hold pineapple juice
  • Inside dimensions: D: 57 cm, H: 85 cm, Volume approx. 218 L
• a wood chip box
• one or two grids to hold the dead animal parts being smoked
• a cover with a handle
• a electrical stove, for heating the wood chips
• extension cord

Electronic parts

• a thermometer keeping track of the temp.
• an arduino to measure the temperature, display it on a small LCD screen and control the heater using a relay
• a 220V relay
• a TMP36 temp sensor
• a SED1531LCD display to show the current / target temp
  • LCD datasheet
  • example code
  • LCD wiki
• a turn knob to adjust the temp

Software parts

• PID library relay control example
