Default First Lab Laser Build

Hey everybody!
I have decided to take my life in my own hands and try to "fiddle" with some old computer parts that I harvested.
Good news...
I did not die of electrocution...
My spelling did, however, suffer greatly...
Here is my build! I think that all I need is the diode and module...
Whaddaya think?

Looks good so far, just remember you need a driver too. Your voltage regulator will work in that regard as long as it is not a fixed voltage chip and as long as you set it up in current regulation mode. Laser diodes need constant current, not constant voltage.

So a diode, a module, and a driver are what I need?
Drivers regulate the current?
I have the LM317 and, I think, to get my 500mA I need 2.5 ohm resistor, but I don't know anything about making my own driver...

Also a ceramic cap never hurt. Also protects against those nasty spikes that diodes hate! There are many different threads in the drivers section that are based on the Lm317 regulator. I cant seem to pull up a thread for a tutorial but anyways. Have fun and be SAFE!

I'd love to see you get this working! What wavelength are you looking to use? 445nm?

Ahh yes the time will come. Even though I am a "N00B" on this specific but on another (PF) not so much.Just now Im doing my first laser related job for a friend who owns a laser company many of you may know ( I wont get into details). Im building five 1.5watt 445nm lasers in flashlight hosts for him to sell on his site. Right now I am just making the cross over from beginner to intermediate.

Ghostcrome- Thanks!
Joe Mo- I have a 532nm Optotronics 150mw pen and a ~1W 445nm Survival Laser (which is currently out of commission so I am thinking of going violet or red...
If red, a nice, deep red- NO PINK LASERS HERE!

This guy was unscrewing it to take out the batteries while I wasn't looking and unscrewed the portion between the driver and the diode and ripped the pins out of the diode!!!!
I was so angry that I almost had a Leonidus moment...
He's paying to ship me a new diode from them...
Survival Laser isn't paying me to say anything nice about them so I won't, but I also have nothing bad to say...
I get their parts piece by piece and put them together...
It's nice...

Thanks dude! Gathering the parts for the driver and getting the diode/module/lens are the final steps...
I am gonna go 405nm or 650nm...
More research needed...
