One of my all time favorite gyverisms was the motion detection water sprinkler pet deterrent.

I used to have a Dog that would love using the driveway as his spot. I've tried all the conventional way to stop him when I wasn't there. They didn't work so I went to the hardware store and got a sprinkler, water solenoid, motion detection floodlight, some wood, PVC pipes, transformer, and some wires.

For there on, every time my dog will go on the driveway, the sprinkler will active and scare him off.

I'd imagine this will work perfectly for those nasty raccoons, and other animals that constantly raid your garbage or annoy you when you are not there.

Email me, if the list is large enough, I'll post step to step plans on how to build one...

Mike.
