This came up quite some time ago.....maybe last year(s) and it was an attempt by the pilots to SAVE the tow planes as they were about to get SMASHED . Bloody dangerous....but it worked !

Prophetic ! ( sounds like my relationship with the ex-wife , until woke up)

If the phone and tablet both run the same OS , then you could then link to each via bluies teeth .

Good onya Tim , the B.B looks good and mean too. -
personal preference only FWIW .........petroleum jelly.(Vaseline)

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}

and I always thought that it was bi-sexual
-
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!
