Hello everyone, I'm new here, know almost nothing about lasers, neither eletronics, but I'd like to learn, and speaking of that; I got myself one of those cheap lasers that you can get at any store, Red 650nm, it was fun to point with but it stopped working, I opened up and saw that the spring that the batteries press against is broke, how does one supply it power?
Anyway, nice to be here
