Doug,
I know the idea of doing a RDP thing is very attractive, but you want a
warm body on site if you are fine tuning things.
How it sounds, and what it looks like up close is impossible to
distinguish via a RDP setup.

I assume you are in Gresham, Oregon? I wouldn't mind helping but I'm in

Just a thought - if you are using an Arduino for control,
wouldn't it be easier to use glass bead thermistors rather
than thermocouples. This type are used by the Reprap

Hi Steve,
the oceancontrols one is the one that showed me that a mux could be used
and is what started the holy grail search for the correct mux :)
awallin also gave me the same link with the good info on multiplexing a
thermocouple.

HI John,
Here are two links that might help:
This one is an off the shelf Arduino shield that uses
the Max6675 with an ADG608 Multiplexer IC
http://www.oceancontrols.com.au/KTA-259.html
This one is an application note from AD about
thermocouples. See page 7 for multiplexer hints.

Looking at what this guy sells from down under somewhere it seems to
have only 4 things on the circuit board a MAX6675, ADG608, and two caps
I think. Judging from the cost of the ADG608 (4x all the other chips) I
assume it is better at handling something like a thermocouple input. But
that is j
That's way beyond my math skills Andy :)

Given the microvolt-level signals from a thermocouple, it's not clear
the signal emerging from a multiplexer would bear more than a casual
relation to the actual temperature. With a

First off I don't have a clue as to how to do that LOL and next I wonder
how you deal with the need for a cold junction reference for the
thermocouple without something like the MAX6675.

There is a multiplexer in the Arduino, as it only has one real A to D stage.
In fact, I am a little p
In my continuing search to get temperature information into the computer
at a reasonable cost I came across a neat thing called a multiplexer.
I'm sure all of you know about them all ready :) but I'm a little slow
in electronics. Anyway my thought is to use a multiplexer to get 4
thermocouples
Using the keyboard with the default setup, I can jog all three axes
simultaneously using the PgUp/PgDn for Z, Rt/Lt arrows for X, and up/Dn
arrows for Y.

Ok this driving me nuts!!
I have 7i43 and I have opto isolated drives for my steppers. I want to connect
5V to +ve side of the opto led and connect the 7i43 to the -ve side. In one
state i.e. "NO step" the 7i43 output sits at 5V in the other state "Step" the
7i43 sinks the LED current and the
