Hack n Mod has a fascinating DIY instruction manual for building a Star Trek phaser that shoots Blue Ray laser light. I’m not interested in actually building a Star Trek phaser that shoots real laser light at all. But I’m interested in the whole idea of posting about how one would do such a thing. The images are interesting. I like phasers and would probably use one to take over the entire world.  If you build one of these things, please do not shoot yourself or anyone else in the eye with it.
