A run of light saber stands for Disney theme parks in California and Florida. The base is made from laminated mdf and frosted acrylic with color changing leds. The displayed lightsaber is sold by Disney and normally battery-powered. We wired it so it can be plugged into the wall power, and added a motion sensor in a machined ring between the base and the light saber. The motion sensor triggers the on-off switch for a set duration to incorporate guest interaction.
