I plan to do a separate project page for the alarm device. Since I did use the TV-B-On to trigger it, I figured I would post a test of it here.  I saw a cat (who I'm good friends with) in the garden, a place she shouldn't be. I placed the alarm device near to her. the results:

She was far more curious about it vs. being afraid of it. So much so, that she came out of the fenced in garden area to check it out. The root reason I made the alarm was to scare away a cat (not the one in the video above) that likes to sit under the bird feeder and tries to catch birds.
