Help with first build

[Laser1234]

Hi guys.

I'm new in the world of lasers but i got my plan .
I have some little questions. Sooo i want to make this one :
http://www.youtube.com/watch?v=CgJ0EpxjZBU
Tomorrow i'm getting an old dvd burner from a friend from which i will extract the diode.
In the video he uses this aixix module :
Amazon.com: AIXIZ 650nm 5mw 12x30mm laser module 3.2VDC: Everything Else
At my point of knowledge i have to solder the diode on the ,,driver" of the module.
so change the 5mw diode with my dvd diode is this right until there?
next point is : is this everything? because in the video he doesn't do anything else just put in 2 AA batteries. don't i need anything between the power source and the module?
another point is how do I know whether the aixix module is compatible for my dvd burner diode. or doesn't this play a role?
The last point is the current of the 2 AA batteries. how do they relate to the power off the dvd diode?
I hope'll understand my english and thank you for answering

Okay, first off, Kipkays "hacks" often don't work, and are just plain old wrong. In this one he does not use a driver for the laser. This "hack" will leave you with a non-working laser. You need a driver to keep the current going to the diode even. If you don't use one the diode will die very quickly.

If you wish to build a working laser, look at the forums.

That should help you out a lot, ultimately, read the forums, there is a lot you can learn about lasers here
