Woah, you guys are nuts!
Our internet has been down for 5 days (cheers Telstra Clear), and I come back and there's all of this!
I am going to start researching more into all of your comments.
Bought 'Making Things Talk' and it's pretty awesome, I'll see where I get before I get the other book.
Had kinda assumed GPS wouldn't be what I was looking for, and at the price i'm glad it's not! & In terms of speed, it doesn't need to be exact - it's a concept mockup at the moment.
Phil - I'm in Wellington, and would love to meet other Arduino users. Also tips on where to buy as the people at Jaycar are lovely, but don't have what I want most of the time. The guy there almost wet himself when I showed him the Arduino.... Odd for an electronics shop...
Will keep you posted of where I get to (beware, when products are coming from the states it may be a good week or two between responses).
-Cheers
