thanks for the reply.
firstly this is not homework... and im not looking to have the code written for me im sure i can manage the code.
im looking more for the experience of you guys in a design capacity.
i have no brief to work to so am open to all options, the reason i was looking at sd cards was for storage space and being able to be read directly by the pc.
the idea is to place the completed project inside a fake egg to monitor temperatures in the nest of a peregrine falcon (captive bread not wild)
this would not be feasible with my original serial logging design
my objective is to log for long enough to reach max egg temp in the nest and also patterns of sitting and night/day temps
logging the temp in 12bit from the ds18b20 means using 2 bytes of memory for every temp logged.
so if i say log every 30secs, that would mean 2880 bytes for every 24hrs
that would be an ideal starting point.
so again suggestions welcome on what hardware to use most appreciated.
