    So quick update I have successfully made a working red laser! I placed it all.together in a little project box and it can make some stuff smoke and yeah it's pretty good for my first time I guess. Thank you so much to all the people which helped me.i appreciate it

    Yes I'm using a 1ohm resistor on the dummy load and do you think it's safe to use the laser diode on this laser driver??

    Alright thanks for the reply I'll wait for more people to see and see if it's okay to use the laser diode

    Alright update so the few posts I made up there regarding about me not being able to measure the voltage on the dummy load is because of me soldering it at a wrong polarity which I corrected it now . The voltage across 4 diodes = 3v The voltage across the resistor is too little for me to even...

    So I tried it out with my 12v power supply and same results.no voltage between the resistor and diode.But when I measure the voltage that the driver puts out it seems like its more than 10 v which I guess is 12 v. I would be very grateful if someone could take a look at these pictures and see...

    Hi so I just made a new driver and it's made up of a lm317t ,3.9ohms resistor,a 16mf capacitor,and a diode. And I connected it to a dummy load and when I try to measure the voltage between the resistor and diode in the dummy load nothing seems to be showing up on my multimeter. Anybody knows...

    The diodes I'm sure I solder the positive side to the resistor and the resistor goes to the adjust pin of the lm317 and thanks for the information

    I see. Thank you for telling me this

    Oh is that so, I'll definitely try it and see And what's the difference between a shunt resistor and a normal one? I'll try to give updates as soon as I can

    I'm basically just hooking up the laser diode to a driver similar to the picture but with no pot and resistor changed to 3.9 ohms.i don't think I can measure the current correctly because my multimeter seems to just go as high as 0.25 mA. For the calculation of the driver, I take 1.25 divided...

    I actually finally got my laser diode to work and it's so bright ,I made this work by using the a lm317t ,capacitor,diode and a 3.9ohms resistor all connected in a breadboard.but once I switch to the driver as in the picture and used a 9volt to connect to the diode ,it lights up properly,but it...

    Alright update so I made a new laser driver which is lm317t current limit.mode with a 3.9ohms resistor but when I try it with a 12 volt power supply with a test load,I can't seem to measure the current across the 1 ohm resistor on the dummy load, would be thankful if someone could help thanks

    i cant seem to find any can you please let me have the link thanks

    Lpc826 not bright help

    So what tips can you give me , I'm going to try again with new diodes
  17. S

    Lpc826 not bright help

    Yea but do you think I might have damaged the diodes because I used a 2.4 ohms resistor which the current output is around 500mA maybe that's too much for the laser diodes?

    Lpc826 not bright help

    I don't think so I tried hooking it to my 12 v power supply and surprisingly it is dimmer than when I was using the 9 volt

    Lpc826 not bright help

    So other than not discharging to capacitor what could I be doing wrong here? I can't seem to know why it is not working correctly

    Lpc826 not bright help

    I thought I could get the current I want with the value of the resistor?
