    2A driver circuit ... Need help

    In regards the 4 diodes in series will I need anything else to make a reliable dummy load ? Or will the 4 in series be sufficient ?

    2A driver circuit ... Need help

    Hey guys thanks a lot for all the responses , OVNI thanks for the detailed response that helped a lot. I decided to abandon the nte1934 and built 2 lm317t drivers in parallel set at 0.9A each giving me the desired 1.8A capability for the m140.

    2A driver circuit ... Need help

    the first image(without material list) is what Is suggested by the manufacturer of the nte1934. the second image with the material list is the one I designed based off of my research and knowledge of the last two drivers I built. some clarification would be great thank you

    2A driver circuit ... Need help

    I know a lot of people buy drivers but I'm more interested in the electrical circuitry in building lasers . I recently built a 0.8mA red laser and a 1.25A blue laser with a m140 diode. I want to build a driver that can operate at 2.0A because these m140s can be pushed to 1.8A comfortably . The...

    First build-need some power supply advice

    EDIT: when the device is powered on and the test LED diode is hooked up I can achieve 3V by turning my pot with the 9V power supply still hooked up . Does this answer my own question ?!?! Lol

    First build-need some power supply advice

    So I built my own driver and although I do not have the laser module installed into the heat sink yet I have put my meter on the output terminals for testing and used a simple led diode for testing also. I read about 340mA output and 6.5V when my meter is on the output terminals . I intend to...
