Speaking of 'coast'
the fly-over thing is kind of weird ( ... no, I don't mean UFO's - but who knows, eh?
Our office is on the coast and close to a big Navy base. The Shore Patrol helicopters fly along the beach line several times a day.
Every so often, one of them flys near or directly over our building.
Our office has a far number of electronic gizmos. Now neither of these things would be worth mentioning - except that much of our building's lighting uses the old X-10 (home automation) protocol. (If you don't know about it, it's basically a really simple, serialized data stream that rides on the AC waveform. You can turn lights on or off or dim from any location.)
X-10 is really cool actually.... until the Navy flys over.
The lights go on and off seemingly at random
Took me a while to figure out why...
Anyone wanna take a guess ?
