Precisely the plan, Wes. The horn serves two purposes. One, it alerts the
transgressor that they pushed the button. Two, it alerts me to fire up the

As others have pointed out, a two pressure hose setup and some simple math
in a microprocessor of some sort would serve the same purpose at far less
current draw, but I'd like to try the radar gun first.
Hell, Jim Thompson went on for two weeks about how to detect a school bus
pulling up in front of the house. I thought this one would go on for at
LEAST as long {;-)
BTW, Jim, what was your ultimate solution to that problem?

Sit in my office from 7:45-8:00AM, so I'm looking out the window ;-)
What I am going to try, when I have the time, is a suggestion that
colored LED's make color-sensitive detectors.
