I keep seeing the mention of "hobby shop", what exactly is that? The only "hobby shops " around me are usually for radio control devices. I do remember hobby shops in the 70's. Where and when do you guys live that you have hobby shops? I really cant think of anywhere else I can get metal tubing other than the hardware store. Is there someone online you know of that would sell different diameter tubing?
ah...
I didn't... the insulation is waterproof - but the probe is deep enough into the sleeve that the epoxy effectively seals against the insulation, and acts as a bit of a strain relief between the probe and the wire.

i just bought a few LM35 sensors and a netduinio. I'm gonna need to build probes at some point and was wondering what your thoughts on using just 1/2" OD copper tubing and soldering a cap on the end of it. Do you think this will work? Don't know where to get the SS tubing otherwise.
I think 1/2" od copper might provide too much air space between the sensor and what it's measuring. Air can be an insulator...
yellow pages "hobby" in your area, and look for a display like this...(possibly an Ace hwde-type store as well)
