Hello I am trying to build my first laser pointer and just getting into lasers in general. I plan to post soon on the welcome thread but currently am eager to fix this build. I tried to mirror the video below the best i could but my laser won't work. I got a 1.8 A driver with my housing from survival laser, just using one 18650, and a 488nm 55mW module from DTR. Does anyone have any suggestions or advice. Thank you.
