I have a problem with the cats getting on the counter. I don't want to

therefore dislike _me_.
So I had this idea. I'll take an old computer. Add a webcam,
servo-controlled watergun, and some glue code (which I'll write), and
I have an automatic cat detector and squirter. If it's put on the
counter and the cats wear reflective collars, targeting should be easy.
If the computer needs USB and doesn't have it, I think I have a PCI USB
card around here.
The only sticking point is servos, where to get them, and how to interface
them to the computer. (I need azimuth, elevation, [or X and Y] and an
on/off trigger.) Anybody ever used them?
Not the answer you are looking for, but....
I know a women with 5 cats in a small condo. She puts aluminum foil on
her counters, and the cats stay off. Cats don't like to walk on foil.
That's certainly easier than an automatic cat-soaker. Does the entire
counter surface have to be covered (that makes it sorta useless for
other purposes) or just the outer foot or so? Adhesive tape sounds good
too, but it's extremely annoying to the us humans there. And that's a
lot of area to tape.
