I used an Arduino Mega because it has most of the analog and digital io, but as you can also see, I had to use an external display with buttons (DFRobot), and then layer on an Adafruit RTC shield, a proto board for probe pullup resistors(or pulldown, cant remember). I later modified the Megamometer code and added some components for driving the fan (the components all up in the air) and the ribbon cable is for the high temp thermocouple using a Max385 TC amp.StorkQ wrote:What a nice project. Did you use a single ADC and an analog multiplexer for probe selection?
How and where did you measure the fire temp? The usual meat probes cannot handle that heat. So probably you used a thermocouple but I don't see a plug for that. Although the first pic might show a new style thermocouple plug.
Thanks ! And BTW.... here's how i like my thermocouples.... well done !Gary_G wrote:I used an Arduino Mega because it has most of the analog and digital io, but as you can also see, I had to use an external display with buttons (DFRobot), and then layer on an Adafruit RTC shield, a proto board for probe pullup resistors(or pulldown, cant remember).

The fan and TC are connected using the speaker terminal block on the end. Here are a few close up shots the way it is today.
Several of my Maverick probes have gone bad, but I am pretty sure (and amazed) it still works.
