Wow, loads of stuff just arrived for me for building the controllers: Here's what came from where:
A couple more Arduino Boards and some spare ATMega processor chips from Tinker.it
I've got a programmer for the ATMega processors from ebay seller Sure Electronics in china: £15+shipping vs £100 in the UK. I hope it works...
The Maxim One-Wire controller ships have been soldered onto mounting boards [incredibly quickly] by Tirna Electronics
There is some more RAM for the MacBook from Offtek
A nice box mounting USB connector from Maplin
And the start stop switches which Andreas sourced from I don't know where.
