I used a small laser pointer cat toy which can be found at a dollar store. Caitlinsdad has some great instructions on how to extract the laser module in step 2 of this instructable :https://www.instructables.com/id/Star-Trek-USS-Enterprise-Phaser-Red-Shirt/. I extracted my laser module leaving the switch intact). I connect it to the battery holder with black wires long enough to stretch from his head to his pants. I solder the wires in place. The laser requires 4.5v to operate so I used a 3v CR2016 and a LR1120. I was able to fit both into the battery holder (one on top of the other). I stuffed the battery holder into his pant armor and sewed the felt around it to keep it in place. I then sewed the laser to the head (looping the thread around the laser module).



To finish off I added some more armor pieces to the arms and shoulders and added black wire around the arms and legs.
