[George Hadley] developed a nice setup to control the color of a replica Lightsaber. A small PCB houses a PIC 18F2221 and three switching transistors for the colors. A powerful LED resides in the tip of the handle, lighting up the diffuser that makes up the blade. But our favorite part is the control scheme. He’s embedded a small RGB LED in the handle, giving feedback as to which color of light can currently be adjusted (red, green, or blue). One button scrolls through the colors and a slide potentiometer adjusts that them.
We wouldn’t go as far as calling this a Halloween prop, we think it’s better suited for serious replica builds. But it would make an amazing addition to the little one’s costume. See it in action after the break.
