Yardwork and a Mysterious Object

After I got back from Tara's place, I decided to do some yardwork. I had some pretty nasty looking plants growing all over the yard, and they had to go. One of these days I'm gonna have to get serious and beautify my yard, maybe plant a few trees and bushes. I also found this mysterious object on the ground. I'm not sure where it came from, but it looks like some kind of an electronics component. I wonder what it's used for.
