On that note ... this doesn't _exactly_ relate to NetBSD, but the
January 1998 issue of Circuit Cellar Ink (a great magazine if you're
into hardware, even if they have been getting too Pee Cee centric
lately) gives plans for a lightning detector (based around a
commercial lightning sensor) that can automatically shut off a
circuit if it detects more than N lightning strikes within an X
mile radius (X being dependant on the hight of the sensor).  The
sensor is only $50 and the rest of the circuit isn't that expensive.

If you're really paranoid about lightning, or you're a weather freak,
it might be worth your time to check it out.
