This was for the Artistic Endeavors' production of Cinderella that I worked on as an intern. The frame was loaned to us. We mounted it to a rolling platform and added the stem (made of chicken wire) and then the Christmas lights. The frame consists of a base, a doorway on one side, and metal rods bent into the shape of a pumpkin. Each light strand is wrapped around one of these bars, the stem, and then to the bar opposite that bar. The wheels are made of Plexiglas and are mounted on electric motors. When they spin, they wind up artificial vines that are stretched out in front of the pumpkin to give the appearance of wheels made of vines from the pumpkin patch. The whole thing is pre-programmed and is operated by remote. The lights and motors are powered by a car battery. I wrote a simple program in PBASIC language to control the light and motor timing and uploaded it to a Parallax Basic Stamp 2 microcontroller. The radio receiver is tied into the microcontroller, and the microcontroller is hooked up to a transistor array that is connected to about a dozen relays. The transmitter sets off the receiver, it triggers the program, the program tells the microcontroller which transistors to trigger, they trigger the relays, and the relays switch power from the car battery to the motors and lights.
That was awesome Aaron. Very good!
