  Detecting footsteps is exactly the purpose I have in mind. Much like the U.S. military “AN/PSR-1 Seismic Intrusion Detector”.

  The real trick will be building a water resistant housing that’s also a decent resonance chamber.
  I’ll post what I I find when this arrives.

  Hmmm, this X-ducer looks like a likely candidate for bodging out an analog seismic sensor. Should be slam dunk setting it up as a perimeter security detector.

No public wish lists :(
