I thought I'd share one of my lightsabers with everyone. While I don't have the tools to machine my own hosts, I take empty custom replicas or kits and install all the electronics. All of mine have sound, accent lighting and many have highly detailed "guts" if you will. Here is my Luke Skywalker from Return of the Jedi. I have an extensive collection of these that I've done so if there is some interest I can post photos and even short videos of a whole bunch. The laser is 520nm, 700mw running on a micro flex. It runs on a single 18650 battery with a built in recharge port.
