Step 5Finish the Blu-Ray...
You will want to gently install the Blu-Ray diode im the Aixiz laser housing by using a small pair of pliers or vice-grips. NOTE: The wiring to the 9 volt battery clip should be done after you have run the wires to the battery compartment. You will understand when you look at it. The diode should fit flush to the housing. Then, solder the Negative (-) wire to the switch and a wire from the other leg of the switch to the black wire on the 9 volt clip. Then solder the Positive (+) wire from the diode to one end of the Resistor and solder the red wire from the 9 volt clip to the other end of the resistor. Hot glue or epoxy (I use hot glue so if I ever want to remove the Blu-Ray, it's an easy task) the Aixiz housing to the original lightbulb mount.
There's NO WAY that's gonna run for more than a few hours without any sort of current and voltage regulator. These diodes run at ~6V and somewhere between 35 and 90 mA. (The current required varies) As Shikari said on the first page, these are supposed to have a lifetime of 5000 hours- you're cutting that down to almost nothing by doing this. And, there should be more of a heatsink than the AixiZ module just to be safe.
Everyone else-
PLEASE, PLEASE read everything you can at www.laserpointerforums.com BEFORE you try any laser mods, Kipkay's or otherwise- You will learn more than you thought possible, and stay safe to boot. These are INCREDIBLY dangerous... Kip's MiniMag mod is, of course, quite high powered for a handheld laser, and this one is Short-Wave- an even more serious hazard to your skin, eyes, etc... Everything bad that happens with a laser is one more step closer to having them banned. Do all us serious enthusiasts a favor and STUDY STUDY STUDY before you try stuff like this. ;-)

Sounds like it's a bad idea in general to run the laser off just a battery and a resistor. A constant-current regulator is ideal, but if you're going cheap and cheesy, it's a good idea to add a capacitor (to dampen spikes that can kill the laser) and maybe a trimpot. (Individual lasers of the same make and model vary; the same voltage that barely gets one to lase may kill another. You can adjust the voltage with a trimpot so your laser is nice and bright but not going to fry immediately.)
I'm not a laser guy, and my understanding of these things is vague, but it sounds like folks over at www.laserpointerforums.com could be helpful in improving this thing.
