So, i want to build a laser, I never built one before, and I don't have much knowledge in eletronics, I know a little bit tough, so I saw a video on youtube of a guy building a laser from a dvd reader, and I think that even though I am dumb I can make one, the thing I want to know is how do I know the voltage and amps needed for the laser? I saw the guy used a tension regulator, but how did he knew wich one to use? do they all have the same requirements?
