I been lurking for a while and finally decided to jump on this and build myself a laser. I have a limited amount of electronics experience, i know how to solder and ohms law, furthest i got in school was Boolean algebra.
Yesterday I ordered a LPC-815 Diode and Aixiz Module from Jake21
Today I am working on building a driver. Now I'v read the DDL Driver Schematic several times and I see that the pot is just used to adjust the current from the LM317. Since the pot is just an adjustable resistor, I plan to substitute it with a 3ohm resistor. Multisim says my current would then be 416.818mA.
Can one of you laser experts look over this schematic and tell me if I'm on the right track? I'm open to ALL suggestions. My goal is to get close to 420mA OR whatever is a good power for this diode(you guys know best).
Schematic Link.... (3 DOTs)

I plan on putting this thing in a flashlight and using probably 2 CR123A, But still open to suggestions.
