Very nice clean design.

I did some measurements on the connections using the meter Diode function.

Diode Test on Meter
Red +  White -   1316
Red -   White +   574
Red +    Black - 1326
Red -    Black + 1360
Red +    Shield - 1315
Red -    Shield +  575
Black - White + 1579
Black + White - 1938
Black - Shield + 1579
Black + Shield + 1938
White + Shield -  001
White - Shield +  001

Blue wire has no connection and is OC.

I would have expected Red and Black to be power, with the white wire to be (TTL) output.
But it appears from the above connections that white is connected to shield, which makes no sense to me.

Comments please.

Yup, a big cardboard pointer stuck to a (decent size) servo, and you could make a big analogue style meter showing the wattage.

Or try another utility like the first one here
see if Autoit will read the text from that.

I have quite a few Compact Flash devices here, memory wi-fi cards etc

The breakout board sold by Sparkfun
has been retired, is there an alternative to this, and are there libraries to work with compact flash style devices like these?

I would use Autoit
as it can "read" the text values from most windows programs such as SpeedFan for temps, cpu load and voltages.

Autoit can also monitor the running processes or if a particular program (window/taskbar icon) is running.
There is a comms library for autoit that can send this data to the arduino for processing.

Detecting a computer crash - write a loop in your autoit program/script to send a serial byte in addition to the other values, when this stops being sent you know something is wrong (I would have a sounder here instead of an LED.

This all do-able, but take it step by step.

Get used to using autoit and reading values from a program (Speedfan or other) window first.
Then write an Autoit program/scipt sending data using the Autoit Comms lib to test sending serial data to the arduino, something simple like a control byte to turn an LED on/OFF.

Once you have those working, you can work on the complete program sending monitored data to be processed by the arduino.

Search the Autoit forum for Arduino projects by others and if you get stuck ask, someone will help you out!. smiley

Are you wanting to vary the serial baud rate for some reason or just generate a random frequency from an output pin?

More details of what you are trying to achieve would help in answering your question.

Added a picture of the connector.

Quick tip for the PCB, you can get rid of that wire link by routing that track under switch S1.

Is there a reason why the PCB is so large?, there`s quite a bit of unused space there.

$259?, wow, I can see schools etc paying that price, but not individuals.
42  Using Arduino / General Electronics / Re: How to ground the arduino? on: May 21, 2013, 07:50:51 am
I guess its illegal to connect this
to the phone network then.

Legal to sell, illegal to use?
43  Using Arduino / Sensors / MSI Barcode Wand Connections? on: May 19, 2013, 02:56:07 am
Anyone used or know the wiring for this?

Looks like an RJ45, see through, with 5 cables going into connectors (red, black, blue, white,silver)

I`m guessing that Red = Vcc, Black = Gnd, Wht = Output/Tx, Blue =  Rx?/Clock?, Silver = Shield?
and that output will be a TTL data stream on white.
and use the PS2 library to decode the stream?

I`d rather there was a space to mount a pen up/down servo where the LCD panel is.

(I know, you can`t please all of the people) smiley

If no arduino, then use 555 PWM circuit with suitable transistor/MosFet
