I haven't been able to reply lately because my 5 yo daughter has been in intensive care because of a seizure, she has sustained brain damage but how much is permanent we don't know, she has got out of ICU today and is in the neuro ward.
As for the relay I picked it because I could get it from RS and it was also on little bird but then they removed it from little bird, it can always be changed if the boards haven't been ordered yet, just find a relay that is about the same size because it is fairly close to the arduino. I'm really happy to see new boards are being made up and the brauduino project getting a life of its own.
I'll be spending most of the next week in hospital with my daughter.
cheers steve
