Hey guys and gals,
I need some sensors to pick up vibration. Needs to be sensitive in two
axis, and capable of detecting being bumped with less than 1/8 inch
movement. It'll feed a PIC so I can work with most any output, but I only
need a single pulse when it's bumped.

Right now I need about a dozen, but eventually I might need several
hundred. And yes I could do it with an accelerometer from analog, but I was
hoping for something simpler/cheaper.

Ideas?

-Denny
