Hello guys today my 2nd 445nm laser died. On the first case i made a driver with a transistor (lm317) and the pins of the transistor hit each other and my diode fried. In the second, i ordered a driver but it never came.. so i built one. an lm317 voltage regulator with a potentiometer powered by a 9 volt batterie. the laser was outputting about 300mw or so. but it was getting weaker and weaker. and today it died. PLEASE HELP!!!anyone knowswhu it died and how to build your own driver for a 445nm diode and what batteries should you use (exept jayrob and flexdrive drivers) Thanks.,...
