I had just gotten my 30mW CR2 laser from DX and I wanted to pot mod it but instead of using a battery I went and hooked up my transformer from which I selected 3 volts. It seems to work great minus the heating if it went on too long. So I was trying to get the most powerful beam until I basically gave up and said to leave it for tomorrow. The laser worked just fine then. Now I was about to try again to get the best setting but the ding seemed like it didn't want to start. So I tried both batteries and power source, but then when I looked inside (yes I do realize this is a stupid and dangerous thing to do) I noticed that there was only a tiny red light inside and its intensity increased/decreased as I adjusted the pot. So what exactly went wrong here?
