[The Yellow Lantern] Mag-Lite 638/520nm combo
The Yellow Lantern
Well I had always wanted to try the legendary rog8811 yellow build... so after the Titan's Fist (which is almost finally done) I built one, and really learned alot.
One thing is for sure that this is one cool laser really bright so much fun.
I really researched this build and of course gathered a lot of info using jayrobs yellow build thread and other sources. I tried this build awhile ago and failed miserably, but with the 520nm diode I felt comfortable giving it a try.
I shorted up a mag-lite host to except a 32600 battery to use as a host. I first tried a sAik, but only got as far as the heatsink. I did not have the opportunity to take my pics during the process, for one there was just to much going on.
I decided to use a 300mW 638nm for the "red" only because I was worried I would not be able to keep up with the 520nm with a 650 or 660nm.
I had a microflex laying around so I had it set to top out @650mA later to dial in the yellow I had to turn it down, then up, then down I had the 520nm running on a microboost so yea all Dr. lava up there
The one thing that can be a pain in a build like this is the beam alignment. I tossed around many ideas, I did not want to wonder away to much from the modders theme here and at the same time not to have to use a bunch of goop to hold the beam in place, so here is my solution.
In this pic I used a M3 .50 flat screw and JB-welded 2 M3 nuts on top. After that I used some springs in-between some nylon washers to keep the tension as taut as possible and NOT have that wiggle that disrupts the alignment process.
I tapped the heatsink with M3 threads under the modules. I then used a FS mirror under the 638 diode and a turning mirror sourced from the PHR sled for the blending of the 2 beams under the 520, or center module.
Sure was fun all that adjusting, but in the end I nailed it and man what a beauty.
I know it doesn't show in the pic, but I have a 594nm CNI and this is totally more yellow at least to my eyes. I even turned down the 638nm diode to get more of the "yellow".
Maybe to much fog
I utilized the skinny axis by turning down some cast nylon and "sleeving the host.
