That's me playing James Bond in the video intro!
(I built that in After Effects)
Step 1: What You Need...
2. Laser guide for pistol. Mine was from a JKX-313. The Umarex just didn't fit the bill.
3. Get the Blu Diode Here
4. Housing for Laser Diode also from Build-a-Blue-Laser
5. LM317, 100 ohm variable pot, 1 ohm resistor, circuit board.
Step 2: Get the Diode...
Disassemble the XBOX360 HD DVD Drive. Here is a good tutorial from The LLAMA
Then extract the diode from the drive carriage. Use care!
NOTE: Not all XBOX 360 HD DVD drives have a 150mW diode. You have to bench test it to measure the mW rating or just buy the diode.
Step 3: Install it in the Housing
How to Install it: First remove the laser warning label and unscrew the housing so it is in two parts. You may have to use pliers or vice-grips or a vice to unscrew it. If it came with an exisiting laser diode in it (5mw), remove it and the circuit board leaving on the housing. The new blu-ray diode gets pressed into the housing. Be sure it is straight and flat around all the edges. I used a pair of vice-grips and carefully squeezed the diode into the housing. Once you have it in your hands, you will see how it is done.
