Hi everyone I am new to LPF. Ive always been interested in electronics and somehow surfing the net came across custom laser builds, so Ive decided to give it a try. Ive been researching this topic for several weeks and this forum looks like just the place to be if you need help. A lot of knowledge on here. Oh by the way I'm building a 445nm blue laser. Currently i have a safety glasses, M140 diode, FMT V2 buck/boost driver @ 1.7A, C6 host with heat sink, and 18650 batteries( also have cr123s). Nice to meet everyone
