|A pneumatically controlled spider. A motion sensor would cause the
legs to flail about. This prop took way too much air and I'm looking for
improvements for next year.
A witch in the tree. She showed up bettter at night with the spotlights on.
Legs - connected finally to a 12-inch pop-up lawn
sprinkler head. They swung back when motion was detected. I'd like to have the
legs swing back and forth like someone is kicking for next year.
|An old drill motor that had an arm connnected to the shoes of the legs. The legs were supposed to kick back and forth, but they were too heavy for the drill motor.|
|A photo of the vairous air solenoids I used to operate the legs, grave jumper, and spider.||The brains of the operation. I used X-10 devices, valves, and 555
timers to automate the system. everything was housed in a Rubbbermaid tub with a lid
to keep rain out.
