DIY-WB construction question

[Brian Renegar]

Mark, thanks for the info.  Yeah, I was talking about the "dogbone" looking 
thing.  :)  Pretty cool idea having the resistor matched with the 
sensor.  Sure does make it easier to just drop a new sensor in, and still 
have it calibrated properly.  If you get a chance, I'd sure like to see any 
pictures you have of the completed setup.

Thanks again,
Brian
