Q-Control Parts List
#1
I'll try and keep the main post updated links.  If you find anything better or cheaper feel free to post your links.

PS:  I don't endorse any seller or products.

ATMega Pro Mini 8Mhz 3.3v PID controller (clone) 

something like this....  Note that there are 5volt 16Mhz version that you want to avoid.... 

ESP8266 Wifi Module

WeMos D1 is a popular choice (4MB Flash minimum)
NodeMcu is another popular choice (4MB Flash minimum)

Thermometers:

In my opinion.  Thermocouple are my choice for BBQ/pit control.  They are rugged and support very High-heat compared to other types.

for food monitoring, you can use either Thermocouples or Thermistors depending on your preference.

ThermoCouples (TC):

Current support is for the MAX6675 chip.  I bought them from aliexpress (or ebay) and can be found for under $3 shipped.  You will need one per probe,  so if you want to build a 4 TC probe Q-Control you will need 4 of these.

There are a few variations that you need to notice.  Some come with a TC probe as well.  Some are smaller, and some will have the headers already soldered for you.  I'd recommend getting ones with nothing soldered on them giving you the option of mounting and connectors.

Thermistors: 

Q-Control supports analog thermistors type probes.  I would suggest the Thermowork pro probes, or the mavericks (current versions)...


Servos:

5V servos....  really depends on your budget,  I get cheap ones like this but always have extras in case of problems.   

Fans:

5V fans will make the entire build easier to deal with than 12v fans.  Depending on size of BBQ you can use either a blower type or inline type fan.  Note that cfm of fan is important but also the 'static pressure' of the fan will determine if it will work for stoking your Grill....  not all fans will have enough strength to work.

Fan Control:

For fan control you will need a diode and a mosfet to control fan speed.  I'm in process of testing this one...  (FQP30N06L) 


Prototype boards:
I prefer ones that 'bridge' like this:


usb power connector:

This is important as the usb connectors on the esp boards don't have a 'pure 5v Vin'.... and it allows an easier build.  (BTW: some new nodemcu's have a pure 5v usb line). But you'll need to make sure your fan/servo/etc don't pull too much amps through the small traces on the nodemcu.

Also,  I may try out an integrated battery version.  Then you could use this as the usb connector...
