Guys
sometimes it is really easy to get an answer within couple of minutes on this forum..
Sometimes it is not and you have to pay a tax.. lol
So i was really impatient till someone explain what this big resistor is for, and i decide to remove it.
Well, what i was expecting..
I blown my laser modul of course.
But i had 3 modules left with same problem with dimming so i was experimenting though.
i have figured out that i need to lover the resistance slowly..
current resistor is 0,8ohm so i have found 1,4ohm resistor and i connected it in parallel with current one.. it gave me a 0,5 ohms..
Still not good results..
Then i took resistor from my dead module which i burned because of lack of any big resistor and it gives me 0,4ohm in total..
And here it comes guys..
I HAVE GOT A STABLE OUTPUT AS YOU CANT EVEN IMAGINE...
Potentiometer is in a position as it comes from manufacture and it is supposed to be 5-10mw..
But it is sooooo damn bright that i can definitely say at least 50mw..
also there is no marks of overheating.. even resistors stays cold.. but probbably because they are two not one.. i dont know..
so i think that 0,4 ohm resistance is a way to go if you have a problem like me with dimming and not getting the stable output just from turning the potentiometer..
now all i need to do is to find a small resistor with 0,4ohms to make it fit a pen back... but probably i will need to buy it as i doubt i have one.. anyway i hope that my other 2 modules (lasers) will thread in the same way as i am not going to work on them till i have 0,4ohms resistors..
i hope that i contribute to this community just a little bit and it will help you guys too.
Thank you
Milan
