Remember all the people warning you never to look directly at the sun because you will go blind. Well believe me when I say do not look into the barrel of this gun because it will make you blind. This DIY Pulse Laser Gun was built by Patrick Priebe who you might remember from the Iron Man Repulsor Light Laser Glove Project. This is what you get when you convert a ton of energy into light energy in a fraction of a second. Looks fun enough to build but I probably won’t since I would probably end up with a few holes in my hand or something.

“It holds a small pulse laser head, capable of generating a kW-pulse of coherent infra-red light. One shot can punch through a razorblade, plastic, 5mm styrofoam when focussed. Effective range on 3m (dark surfaces)…you will see a stinging flame and a 5mm stain will remain on target. The goal was, to create handheld device…AS COMPACT as possible. Its 320mm long and weights about 2 pounds.

Materials used: Plexi for the center-plate, and brass / aluminum for the casing. Each and every part, handmade…took about 70 hours of work.” (From Hacked Gadgets)
