I'm sorry for sounding like a noob when most people would say "USE GOOGL!!!" But I did look at other threads and just wanted to verify some stuff.
First off, I got a laser + aiXiz focusable lens from daguin. He told me the PHR is a blueray (violet) laser diode, and runs safely at 120mA.
So I'm looking for a driver, and debating "Do I buy one, or do I make one" So, I guess first, is there any math I need to know to figure what resistance to tune a pot. so i can be around 120mA and not over?
* Also, What schematics are best for custom drivers? I have the right tools, should have the parts, and I have oscilloscope if needed.
*If I was to just buy one, is there anyone on the forums that pre-tunes it so my laser will run happy?
*Can I run it off 2AAA batteries? I dont know the diodes voltage...But I have a old LED flashlight, runs off 2AAA, and I can easily hack my module to fit inside it.
Thanks for your time, Hoping to get this laser up and going this weekend
