Laser blaster: a homemade mini-burner

This guy has built a real mini blaster! In the video, he shows how his homemade gun burns holes in various objects, reminiscent of weapons from sci-fi movies. A great video for DIY enthusiasts.

Such laser devices are often made from powerful laser diodes that can be found in old DVD-RW drives. These lasers are capable of not only reading discs, but also burning through plastic, wood, and other materials.
