Hmm, the problem is there isn't alot of copper tubing... most of the tubing
is synthetic and doesn't really conduct heat that good... maybe insert a
small piece of copper tube between it and epoxy the LM35 to it... But
submerging it in the water should be a bit easier... just need a really
small packaging (so-8? or maybe i should check if maxim has a small LM35
like chip...)
