    Pit Meter - iPhone app for the HeaterMeter

    Using the latest snapshot (with pushbullet integrated) it appears I no longer get push notification for pit droid. Is this a known issue? [truncated] {"Message":"An error has occurred.","ExceptionMessage":"Authentication failed because the remote party has closed the transport...

    "No Pit Probe" above 450 Degrees?

    Apologies, I mean 450F... The thermocouple works fine until circa 450, and the other 3 jack probes seem to work fine (albeit I have not tried them above 450!)

    "No Pit Probe" above 450 Degrees?

    Hi Brian, I've checked and it appears I'm not getting a reading at pin 21?

    "No Pit Probe" above 450 Degrees?

    Hi Guys, After finally getting my HM Thermocouple version working, I seem to have an issue whereby "no pit probe" is displayed above roughly 450 degrees. If I leave it and it drops below it comes back alive again. I've checked all joints etc and they seem correct, it's also spot on below this...

    thermocouple connector sourcing question

    I agree it's quite an expense for 1 component, but I couldn't find a cheaper Heatermeter PCB friendly alternative :-/

    thermocouple connector sourcing question

    This is the best deal, I had to purchase one via Ebay at the cost of £6.77 before the July shipping offer at Farnell.

    Thermocouple Readings Sky High

    Hi Guys, Sorry for late response, I was on slight sleep shift and just woke to my first alarm to check on the progress of things. It's now 2:30am and things are looking nice and steady. It seems I'm currently experiencing the legendary stall... http://postimg.org/image/9k1sgiwhz/ I've checked...

    Thermocouple Readings Sky High

    Yes, the strange thing is, once it's come down, it reacts what I presume is normally... It also drops back down very quickly too (Albeit not past the lowest value if it was still settling. I have a pretty decent multimeter I think (http://goo.gl/yLVZHS), but like most things, it's probably far...

    Thermocouple Readings Sky High

    Howdy Ralph, This morning I replaced all the caps and resistors, I'm not sure how to confirm the value of the caps - but I ensured they came out the correctly labeled Mouser bag! I was considering ordering a separate batch of caps just to make sure they're correct. I love the option of the RD...

    Thermocouple Readings Sky High

    Hi Ralph, I get these readings when shorting the 2 points, to I presume that removes any concerns about the TC? Don't be sorry, it's just my luck :-(

    Thermocouple Readings Sky High

    Okay, I woke up early this morning and decided to resolder all the caps / resistors / amp. Still no luck, it still does the same thing. As per the testing procedure the Amp is getting a nice steady 3.25v - shorting the 2 points shown I then see the voltage start high and count down. This...

    Thermocouple Readings Sky High

    I checked all these points with my multimeter and get a solid thumbs up from the buzzer and each point as expected... Ralph, I'm sorry to trouble you with this and really appreciate your help. Right now I feel like throwing it in the trash!

    Thermocouple Readings Sky High

    Hi Ralph, I'm pretty stupid when it comes to PCB's and am having a hard time tracing the routes, I've no idea how you trace it to the 100k resistor?! Are you referring to the one near the 68 / 22k resistors? :confused: Edit: I presume you're talking about the 100k near the pit jack...

    Thermocouple Readings Sky High

    Hi Ralph, Sure thing, it's set to the Thermocouple and 5 mV/C and has been all along... I just want to check, when I ordered the Mouser project some parts were unavailable so I ordered alternatives. Instead of these (http://goo.gl/8ClVKX) I ordered these (http://goo.gl/eDGrwm). Clutching at...

    Thermocouple Readings Sky High

    Hi Steve, TBH, I've scrubbed the hell out of the board numerous times... I think the joints are mostly very clean and tidy and I see no issues... Perhaps it's a damaged board? That would be very upsetting as I'm pretty heavily invested in it :-(

    Thermocouple Readings Sky High

    Hi Ralph, I agree, but to be honest I've exhausted my experience on this one... I think it's time to give up. I tried it tonight and it seemed accurate for a while against a proven thermometer, but is now showing an error of 100 degrees. Oh well, I guess I can always resort to a standard...

    Thermocouple Readings Sky High

    Hi Bryan, To be clear, I'm seeing updates every second, it's just the initial settling of the temperature once the points were shorted took some time, in the order of a few minutes. It's now steady at EXACTLY the right temperature though and seems to be responding perfectly to further changes...

    Thermocouple Readings Sky High

    Okay, I've resoldered a new Amp, and either by coincidence or pure luck it's settled at 79 degrees. It did take 5 minutes to get there with a wire shorted?
