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?

:drool:
 





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!
 
Word up everybody!
This forum simply rocks...
I really think that anyone who has time and a little cash could build anything! I can't believe I got this thing going!
Can't wait to not be a NOOB anymore...
 
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. :D

Off topic, I am in the market for a 1.5 445. Let me know when you get this going :)
 
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!
Mikesnap- JEALOUS!!!:worthy:
 
Thanks! It takes a little time

@Joe- PM sent with details on the builds I'm making
 
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!!!! :gun:
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...
