Cheyenne writes in about the homemade laser saber – “I used a reflective slider and small rare earth magnet. Very Happy I think it looks really nice with the new red 100mW. I only powered it up with the red 100mW a couple times on the video. I tried not to look at it. I really need to get some safety glasses for the red 100mW. I don’t really know how dangerous the diffused light from the saber is, but I’m not going to take any more chances then I already have.” Link.
