So, I'm not sure what was going on but I just got it to work again. Even unplugged it and plugged back in a few times and it seems to be working every time.

The heater meter board doesn't seem to power on at all. No LEDs and nothing on the display

My HeaterMeter just died on me. Is anyone still selling assembled HeaterMeters? I struggled mightily soldering my first one and don't really want to do that again.

Been loving the app. Thanks for all the hard work. I'd really love to see some kind of notification for the app that listed the current temperatures. I'm thinking one of those notifications that doesn't go away until the app is completely closed out. I'm a java programmer so if help is needed...

Got mine up and running last night 7/16. 4.2.4 with TC. Will be doing a first cook tomorrow.

Yeah, I have to say it feels great to have it all working. I thought I saw a thread on here were people were posting about their working heatermeter builds to track how many were "in the wild" but now I can't find it.

Last night I paired up the RasPi and also plugged in my thermocouple. Everything is running great. Thanks again for all the help everyone! I let it run on my desk for a few hours last night just to be sure everything was working well. I'm planning to do a pork but tomorrow on my UDS so we'll...

So I replaced the BS-170 that was bent over and had the long leads, I removed the 10k resistor that was mentioned much earlier in the thread as not needed on my setup because I have the thermocouple, and finally and most important I replaced the 3.3v regulator. I only had time to boot the board...

Thanks for the info. I really appreciate all the help and information everyone has provided so far. I did order 2 new 3.3v regulators. When you say to take out the output leg does that mean I have to keep in the ground and 5v legs somehow and just pull out the 3.3v? My replacement parts are...

Yeah, I just checked again the 3.3v reg is in IC4 right? I checked again on the voltage and the center is reading 5v. The the other leg is reading about 1.4v and then the last leg is ground.

I tested the 3.3v reg and one leg has 12v the other doesn't get much reading at all. I just placed an order with digikey for a replacement part.

I'm still not having any luck getting this back to an operational state. I've been testing voltages and it seems like all the places on the ATMega chip that I should be getting 3.3V I and getting closer to 1.5. Also, on the BS170 that is next to the J7 (I believe it controls the LCD backlight)...

The RPi boots just fine. Tried booting the HeaterMeter by itself. No LEDs, no LCD backlight, and the LCD just displays a black blocks on both lines of the display.

So, I walked away for a bit and came back to it. It seemed to be powered off so I unplugged power and plugged back in now the LCD backlight doesn't turn on anymore and no LEDS light. The LCD shows a blinking cursor and the OpenWRT says there is an error communicating with the HeaterMeter. What...
