Just wanted to say thanks for all the help, I had my first cook with the heater meter this weekend (just 2 thermistors one for the pit and one for the pork butt). no air control yet, other than manually stuffing balls of foil in the intake holes (it's a DIY ugly drum smoker) but the graphing of...
Today I get -0.1 on the Circle by TC+ and on pin 6 but 3.25v on pin 5.
I give up... I'm going to order a couple of Thermistors and just use them for now and one of those cheap AD8495 amps off ebay and see if I can get that working when it turns up in 4-6 weeks.
Thanks for all your help!
Okay, I've found the issue, I'm just not sure what causes it.
I get no voltage on the J2 probe 0 point. following this back I have continuity beween the J2 probe 0 and the bottom leg of the 100K resistor and continuity between the other leg of the resistor and the PIT pin (pin 1?) on the big...
Looks like my smd soldering is all over the place, pins 2 and 3 go to ground and the 1 n capacitor is connected to more than just the 10 n capacitor.
But if I can just disable probe 1 and put probes in food 1 and food 3 (pit and meat) then I'm happy.
by off the shelf thermo couple amp I mean...
So I'm all built, only the display says - No Pit Probe - with or without the thermocouple connected (I've set it to thermo couple in the web interface). Is there anything simple to check? I've shorted the thermocouple inputs together and nothing happens but if I touch the board with my finger I...
sweet!! are there instructions for the 4.3.4 board somewhere? the ones linked aren't quite the same as the board I have. (but I think I've got it right so far)
How lucky am I??

Now I've got the middle pins on the top shorted together and can't for the life of me get rid of the solder in-between.
Have I massively underestimateaded the difficulty of the smd soldering or will this still work?
I was trying to solder on the Thermo couple amp and in trying to reposition it I've pulled the top left (as you look at it) pad off the board.
Is there any way to recover from this or have I killed it? If I have killed it I assume I can continue with the rest of the board and use a probe...
Without doing my research properly I ordered a v4.0 board rather than a v4.2.4 so my question before I order the rest of the components is
Whats the difference between the two? is it just the thermo couple support.
I'd like to use a thermocouple for my pit temp, my soldering skills are okay I...
