Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

newbe here from VA. Been doing a lot of research on this site. Great site. I will be building my first laser soon. My biggest problem is finding info on using a dmm to set the pot and where to put the leads. I have some experience with a DMM as I like to build stuff using leds. Any help would be great. Any tutorials that are easy to find on here to help me out ? Thanks Mike
