Hey Martin,
Good to hear you've got one of these too.
Yes I meant [comport] with the xbee rather than [hid] sorry, getting my physical input objects confused.
Will check out the links you provided as part of my getting up to speed.

Which is a vital £0.04.6 of equipment as the sensors pins are way too tiny to be poking bits of wire into. These attach to the bottom of the board and then 2mm cabling attaches to them and out to the Pi.
Got some off ebay as farnell has a £20 minimum spend that's a bit over getting 10 of those suckers. So going to have to wait a few more days as I can't find any in my vicinity at all. Bollocks.
We did put our pi prototype/breadboard together though:

which will be useful for experimenting.
Off to gen up on i2c, python and other such things I currently know nothing about.
Back soon with further info.
Cheers,
Julian
