Ok, my name is Liam. I finaly managed to create a working laser driver. I have an lm317 chip, and instead of a pot and what not I put a 0.32 ohm resistor between the apropriate pins, and i have a capacitor to turn block "on spikes".
I originnaly built this for a red diode, which i pulled out of a DVD player. Unfortunately, I omited to use a housing, thinking that the heat sink already wrapped around it would do. So, I burned it out.
So now i am back, with a few more hours of research behind me.
What i am looking for is an extremely powerfull laser pointer. I do not want a toy. I do not want something I could buy in a dolar store. I am looking for an epic electronic project. It has so far been a legendary journey, wich i have enjoyed greatly. I am now ready to try again, now that i have a few more funds (I am sixteen, so if i want to try a project, I have to find a lawn to mow or something of the like.) I would like to order a powerfull green laser, and a laser housing.
To sum up:
What I have is this:
An LM317 chip
Several hundred assorted resistors
6 Lithium Ion Rechargable 3.7V AA batterys
What I need(or so i beleive):
Laser housing
Green laser diode
Resistence to use with the LM317 chip.
Can someone please help? I dont know how to calculate the mAh required for a diode, I dont know how to find a housing that will fit the diode, I dont know where to buy the parts so i dont get ripped off. If someone could please help me...
On a side note, I do nto wish to have an endless stream of drivers suggested using potentiometers. I believe that one of you can give me the correct resistence to add to the LM317 chip. That and a few links to reputable sites is all that I require.
If you have read this, thank your for taking the time to read it. If you can help, thank you again.
Now lets make some lasers!
