How to Make a Handheld Laser Pointer

This is a rather cheap handheld 5 milliwatt laser pointer I made that runs off C batteries. It is kinda bulky though (about 7.5*7.5*5 cm), but it still comfortably fits in my hand. I will apologize in advance for the fact that I made this instuctable after I was done making the laser.

Disclaimer: I am not liable for any stupid things you do while building this or while using this.
