i just came across this and thought i'd share... i ordered a one-wire device from spark fun, but realized i'm better off starting with a simpler measuring device, so i started looking into thermistors - only to realize their non-linear quality:

i was particularly interested in the "Hardware 'linearization'" section... anyone tried this before?...
