The-Smokey-Powell Printable case
There are three case types here. A high resolution single output version for plug connectors, a low resolution version with and without antenna, and DIN mount version with large openings and easy access for using screw terminals. Also included are the necessary button pins (You will need to print 4 of them) as well as a stand (Print 2 if you want to use it).
The case is assembled using 8-32 machine screws. The screen is held on using 4-40.
The Particle Photon Wifi Blynk controlled BBQ Smoker controller
This controller reads temperature through a thermistor. Control of your smokers heat is made through a fan or Solid State relay. It has three extra probe inputs to be used as meat probes. Wifi is used to connect to the cloud.
The blynk app is used as the main interface from your phone or mobile device. It is worth noting that all the information runs through the cloud. This means one could be shopping for supplies, while also monitoring ones bbq back at home.
A 4x20 I2c LCD is used as a local display and four buttons as the interface controls. The local interface is a little clunky. The main interface was intended to be the blynk app.
This controller can use replacement thermistors for Weber iGrill2 grilling thermometer. Or any other thermistor that will work with a 10k ohm reference resistor.
For those that use the circuit board I designed. The Outputs are sinking.
