Pressure sensor for water tank/should be level sensor

I'm trying to track down the article, all you need is a plastic sight
gauge to put the 2 foil strips on. That was one of the great features
of the design. I can't rmember if it was in the PIC section or the
Basic Stamp section, I know the article was before Jan 1997. I had the
article and used it for 2 different projects where I was working once
in the fall of 1997, and the other in 1998. My copy of it got lost
when a storage unitwnere I had a lot of reference material stored
developed a leaky roof.

gauge to put the 2 foil strips on. That was one of the great features
of the design. I can't rmember if it was in the PIC section or the
Basic Stamp section, I know the article was before Jan 1997. I had the

Hmm, sounds like it would work. I'll look into the N&V article, and please
let me know if you find it.
Thanks,
