looking excellent and wow i just noticed how big your RTC module is, even by most thats pretty big considering the size of the components, what are those 3 yellow bars though they look almost like jumpers? if thats the case i might need to order some more bits d'oh
i'll most likely be pestering you questions on the temp probes and the Real time clock module once i get my bits, but it looks like we are pretty level regarding our progress (ok your alittle ahead).
now see the ethernet shield was something i personnally didnt really see much purpose to in this perticular build, what do you plan to network it to? another controller/Hub a proper pc? etc....
you thought about doign anyform of data logging? i'd like to use a standard USB stick for memory failing that an SD card.
Oh its exciting where to go next XD
also noticed your using a Duelamore(probable horribly butchered spelling mistake but im tired and CBA to check...you know what i mean) Looks like you might need to upgrade to a mega soon its looking pretty cramped
