hurrah.

My USB connector for my RFID reader is here, and I've got it working relatively quickly. My reader is an ID-20, slightly different to the reader in "Making Things Talk", which is an ID-12, but the only difference seems to be the range it will read at (the ID-20 is a little stronger). I've used the example code from Making things talk to get it working in Processing, and I've now been able to give the cards their names!!

Maybe little 21007683C0 will be rain.. I imagine it will be a simple case of replacing the button code I've been working on with the RFID code, and instead of it looking for button presses it will be looking for strings of characters. One thing with the reader is that it can't tell when a card is removed, just when it appears, so any kind of resting state with have to be done with a timer.. if that will work...
