This is something ground-breaking to your kids playing. As a kid, did you ever wonder how to make your own shooting gun has actual laser beam?

This is another DIY method on how to assemble one on your own, a real, high-powered blue laser into a plastic Star Trek Phaser.

There are two ways you can get the blue laser you’ll need for your phaser—you can buy one on the Internet for about $30, or you can salvage one from an old Blu-ray or HD DVD player. If you opt for the scavenged laser, be forewarned: You’ll have to build your own driver circuit, a task that’s pretty easy by circuit-building standards, but not for someone who doesn’t know his way around a soldering iron.
