Hi, Rog. Cool stuff. I was able to make a light saber using an old car's motorized antenna way back 1991! LED's (green & white mix - where you attached the laser) were used alternately to produce the color hue of Luke's saber. I covered the antenna (glueing the tip) inside the saber's toy that extends when flipped, then glued the other end at the base. It extends & closes faster! I made one for my cousin using red LED's (he wanted to be Darth Vader - since he has the "mask & voice synthesizer). Handles used were old metal flashlights (I needed the switch with the red button), since i'm a penny-pincher, had no work then). Sold our Saber toys at ebay for $50 (Luke's) & $40 (Vader's). Now my son (12 y/o) is into electronics, he wanted me to help him build the same model of Luke's saber. Hope I would have the time to build another (since I'm busy at work). Hope you could build the same & upload the video here. "May the FORCE be with you!"
