I was working in the Lab late last night ...
Giant Scary Bat
My inspiration for this project came from this fantastic site
More details to come. I'm working on a simple blueprint showing dimensions along with instructions and specs.
GSB will be mounted on a trellis overlooking the entrance to my haunt and use either a motion trigger or pressure mat. You may recognize this as a giant version of the little toy which hangs from a string and flies in circles.
