I present my most terrifying laser creation as of yet...the remote controlled death ray drone bot! This beast packs a potent 2W blue laser that fries anything in it's path. It can walk around and shoot it's death ray at the touch of a button.
GOGGLES!! If you want to use strong lasers, you MUST use laser goggles. It's legal to build something like this and it is safe if you are cautious and always wear goggles. http://www.survivallaserusa.com/
