The idea is that you plug everything in, and then write all your code on the computer.  Which means that it all needs a way to talk to the PC, which is why they have all the USB plugs.  It also means (I believe) that the Phidgets won't work without a computer, while the Wiring board can work stand alone.

Is it possible to communicate with Phidgets using Processing? I've got a Phidget RFID-Reader (USB) which I like to work with  using Processing...

Hmm. I was playing around with Phidgets a while ago, and I used Java for that, receiving and sending vars was not difficult, so if you can do it in Java, you can do it in Processing. I remember that Java suport was a bit beta, but it worked.

I also have an RFID Phidget and am working to figure out how read from it and use it to hit a MySQL database. There's not a ton of documentation lying around.

I'm using it for my thesis project; so I'll be playing with it for a while. Samuel Sjoberg (http://samuelsjoberg.com/archive/2005/03/phidgets-and-java) has some useful classes for the card on his site.

do you all know about gumstix (http://gumstix.com/)? they are tiny linux computers and are relatively cheap. you could potentially write a processing program that lives on a gumstix and works in a standalone way, much the way a wiring board might.

I've been having trouble getting processing to connect to Phidgets. Using the following code I get the same results weather my device is connected or not (false, 0).

 Phidget myObjRef = new Phidget();
 
 boolean attached = myObjRef.GetIsAttached();
 int serial = myObjRef.GetSerialNumber();
 println(attached);
 println(serial);

Is there anything else I have to do besides include the phidgets.jar library?

From Phidget's Java Docs:
Quote:
public class Phidget
extends java.lang.Thread

Version:
1.0.5
This is the base class from which all Phidget Devices derive. Don't cerate phidget devices directly using this class. Use the specific class for the device that you wish to access.

and also, attaching isn't instant, you'll have to wait until it attaches:
while(myObjRef.GetIsAttached()!=true){} //if it isn't attached this will hang the program, but otherwise it'll work
