46  Using Arduino / Project Guidance / Re: LED Control based on Windows System Values on: May 27, 2013, 10:59:48 am
I would use Autoit
http://www.autoitscript.com/forum/
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.

I guess its illegal to connect this

to the phone network then.

Legal to sell, illegal to use?
52  Using Arduino / Sensors / MSI Barcode Wand Connections? on: May 19, 2013, 02:56:07 am
Anyone used or know the wiring for this?
http://www.barcodemuseum.com/MSIData/BarcodeWand.html

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?

Thanks.

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

It reminded me of Robocop by the way.

What about Han from Enter the Dragon?
X-Men Wolverine

I agree, the demo video was too short.

I imagine quite a few people would be interested in that "learning shield".
I would add a small sounder to it though. smiley-grin

Is that a battery in the top left corner?
59  Using Arduino / Project Guidance / Re: Looking for USB Host overview on: May 05, 2013, 06:13:54 pm
Google Search leads to this.

And this

No USB required?

The question is too general, you need to know what USB device you want to use and start from there.

http://www.circuitsathome.com/products-page/arduino-shields
"The following device classes are currently supported by the shield:

    HID devices, such as keyboards, mice, joysticks, etc.
    game controllers – Sony PS3, Nintendo Wii, Xbox360
    USB to serial converters – FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers
    ADK-capable Android phones and tables
    Digital cameras – Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP"

Support for more devices is currently in development.

BTW that page does not display correctly for me in either Firefox or IE unless I make the browser fullscreen, which I vary rarely do. (Unless someone posts a megapixel picture to the forum) smiley-grin
