Hey everyone, I saw the minimag mod of turning the flashlight into a laser. I got excited about this and bought the minimag. I then looked for a diode and I think I am going to go with the 112d ld, 115d ld, or a sony diode. I got reading though and i saw that running a diode straight from the batteries is not very good. Sorry, I am sort of a noob at this stuff. So I was just wandering if there is any way to make a very small driver so I can regulate the current to my open can diode? Is it really necessary because the voltage is going to be 3v from two AA batteries? Also if you have any other suggestions please feel free to comment. I am just wanting to produce around a 300mw laser with the minimag. Thanks for all of your help!
