    yes it will work but you introduce an error in the cold junction circuit and the possible variable of oxidation of the rotary switch. not sure about using SSR's as they are not a physical connector. The question about 3.3/5 volt ........the Arduino board is a 5v device...the 4 channel breakout board is a 3.3 v device .....there is on the board the possibility of making it 5v with a solder bridging circuit which must be configured { soldered } to make them compatible. The sketch you provided compiles OK and as you've said works ...........no problem therefore ; its more likely a hardware issue , rather than a coding one. Debugging the circuit is a lot easier if you have serial monitor routine to show up any fault conditions as the libraries provide. I suggest you get Bruce to check the supply condition {3.3/5v} on the breakout board , and again as previously noted try bridging either or all of the TC 's together without the water test .

    Who is digressing...............I think we would care to know if there is a mismatch in the hardware side from the MAX breakout and the Arduino. You wanted the help .....NO ??

    I think the board they're using is solder selectable. {3/5v}

    what happens if you touch { join electricly } all four or pairs .....not in water ???

    Bruce ........if you send me via PM a copy of your 'ino sketch' ill have a look thru it....if you wish. I'm not an expert but it should be straight forword enough !

    Or this .........

    I wish ! Now at the Gold Coast , bit of shock from -15 c..

    Hope you get a good turn out................I cant get there ...this time ! Im in transit at Singapore atm from Oslo to Brisbane .....wecom to the Warm again !

    Greetings forumites, I will be away for a month from today , wishing you all a very happy and safe ; MERRY CHRISTMAS. [ for all that celebrate the occasion that is ]

    OK thanks Mark, just wondered if there was any ID on the board. The 4D ones look good too ......bit on the pricey side though.

    OoohK, thanks Jim. Yes that's the one Bruce , flying out of Clare Valley now that YFFl is resumed to the woolly jumpers and cropping. Catch up some time in the new year .

    Hey Kyle, nice OLED, whos' is that.?......I been using the Freetronic one ....that one looks better size wise.

    Bruce, I've had a play , some time ago with this and it seems feasable. Mine was only 2 channels and I did play with a MUX for the thermocouple amps , but I had other things to get on with, so only ever got to the point of proving (satisfactorily the principles ) rather than hard prototyping. There are many options re thermocouples which are a lot cheaper and the thermo. amps include cold junction references making it pretty straight forward. I'm in a bit of a spin at the moment (time wise) but I see if I can drag out what I have to refresh the grey matter.

    Now I think you've hit the nail on the head!

    with respect as I have only speculation..............that as the elevator is quite neutral and the trim tab is fully Up , that as an attempt to get a hopeful measure of up elevation on very jambed elevator ?? Or am I being fanciful .

    Gee with an adress like that you shouldn't be 'thirsty'. I find 800grit paper cleans up the oxide well enough to re-tin the wire. Pleased to help out................regards Ian
  22. cherk
    Where are you based? Ican give you 2 or 3 pair old stock...............needs cleaning oxide off the wire and re-tinning ie: soldering the ends.

    May I suggest the CH750 may be more suitable......chuck in a subaru EJ22 with 130 ponies.....

    So where did the Sting go in this thread ??
