The unit is marketed more for your own pets like dogs and cats. They are 
widely used both for livestock and small animals. Here's a link to the 
manufacturer. http://www.fishock.com/  I don't think the are harmful to 
normal humans and most other critters. Both the wife and I have been 
zapped by it when forgetting it's on, and we are still living. I think 
the battery powered units  pulse for power savings, but this is AC 
powered and I don't care about the current costs. We have not noticed 
any interference.

Are you saying your schematic is available, if so I would be interested, 
the case is big enough to house a small circuit board and powered off 
the 120 VAC.

Since the last neon lamb I had burned out, I'm going to have to order 
something, so any illuminating device would be OK and could order any 
other components at the same time.

Thank's so far for the comments, keep them coming.
