Right now I just finished soldering a Daedal DDL driver (like the one in this picture in the first reply at this hyper-link http://www.laserpointerforums.com/forums/YaBB.pl?num=1227655714) and I want to know if it is ready to hold a red SLD1239JL-54 16x DVD burning laser diode? I did make a few substitutions in the circuit. Instead of a 47UF 16V tantalum capacitor I used a 47 UF 35 volt electrolytic capacitor and for a power supply I used four AA batteries. The voltage reads 5.83 volts regardless of potentiometer setting. The amperage does change upon potentiometer adjustment and goes to 11.03 miliamps at maxiumum resistance and when the potentiometer is at minimum resistance it goes uo to 126.6 milliamps. Is the driver doing what it's supposed to do? Is the laser ready to be mounted on to the driver? If so, do I have to adjust the pot to a certain setting? If not then tell me whats wrong. Thank you.
Added message: I tested it again and the voltatage is now 5.78 volts.
