Thank you. My cat never tries to get out. If so I would buy a single wire electric fence and run it across the top edge of the chicken wire. I bet that would keep those raccoons away.
I hope E.T. sticks his LED lit finger out of mine one day. HA!

This was worth doing. I got the foam ring frame and mirror from Hobby Lobby. I enjoy looking at it as I walk by. Its like a alien portal hole in my floor.
I tried his circuit on a breadboard and found that it did not consistently work for me in my water/essential oil Diffuser. So i added a second transistor to be a current amplifier and put in a buzzer also. Now it is working fine.
