Update: New and better build here! (358mW's!)
http://laserpointerforums.com/f51/build-tips-7-color-laser-using-adjustable-sled-mount-heatsinks-41942.html
First build:
I finished my 7 color laser and would like to share some build tips.
For the guts of the project, I followed the tutorial from rog8811.
For the housing, I decided to go with a clear enclosure using 'push on / push off' clicky buttons. (I needed something with room for my build, which has heatsinks on all of the lasers - still pretty small though)
The polycarbonate material is scratch resistant. It's cool to be able to see inside the assembly of the three lasers and sled!
* Translucent polycarbonate enclosure:
Digi-Key - HM959-ND (Hammond Manufacturing - 1591CTCL)
* Green Modules:

How to: Pocket sized 7 Color Laser with Spiro Projector | Hack N Mod
I just went for the 7 color laser, not the spiro. How Rog gets all of that to fit into his small box is beyond me. Simply incredible with that build Rog.
If you are going to try this, I thought I would share just a couple of things I found out doing this build...
First, the pictures:
I found out that this project is much more difficult than I had anticipated. Rog makes this kind of thing look easy, but it is very difficult to get all 3 lasers lined up perfectly!
Some of my build notes:
* I bounced the dots off a mirror in the other room so that on the 'round trip', the dots would be close to me. That way I could see if they were aligned. Because you want them to align at distance.
* Also, they must be aligned at the aperture as well! This is easy for the red and blu-ray, because they are pointed at the splitter cube, but check for this when setting up your green, which must meet the other beams through the PS3 turning mirror.
* I went with a little thread lock on the lens threads at both the focus ring, and the module. (get perfect focus before it dries)
I did this because the assembly needs to be so precisely aligned, that even the smallest movement can put the dots out of alignment at distance.
Anyway, this is the coolest project I have done yet! Thanks Rog :thanks:... for showing how to do it!

Power settings and diodes:
I stayed pretty close to the recommendations by rog8811 from the tutorial linked above. Here are my settings...
* Red - Sony/Senkat - 92mA's (measured 42mW's with AixiZ acrylic back opened)
* Blu-ray - PHR - 118mA's (measured 110mW's with AixiZ acrylic back opened)
* Green (O-like 10mW) - I picked the best one I had, which measured 9mW's with a CR123.
* Note: I lost a lot more than I should have through the sled optics on this first build, because I did not turn the modules to the best position to get best power through the polarized splitter cube. (a lesson learned)
* The Red started out at 42mW's, and comes out at 26mW's.
* The blu-ray started out at 110mW's and comes out at only 20mW's. (* see note above)
* The green started out at 9mW's and comes out at 4mW's.
Now just do the math for the 'in-between' colors! (yes, I tested them)
* Turquoise - 24mW's
* Yellow - 30mW's
* Magenta - 46mW's
* The white beam measures 50mW’s…
Very happy with these measurements!
Note: The PHR turning mirror is great! (shown below) Also, the splitter cube is fine too! I must not have turned my blu-ray to the best position on my first 7 color build. Because in testing my second sled (all PHR as shown), I can turn the blu-ray and get much less of a loss in power.
I tested at 136mW's (starting out), and coming out at 105mW's through the splitter cube and off of the PHR turning mirror.
My next build will be much better, especially using the awesome adjustable mounts from sightfx! I'll probably settle for a 6X blu-ray at about 180mA's and a 405-G-1 glass lens...

Alignment:
The alignment is definately the key to the build, and is the most difficult part. Above, I mentioned a couple of things that I found useful for helping with this, but no matter what, it will be a chore to get it perfect...
For the green, I ended up using two small set screws that I can use to slightly move the green laser for adjustment...
Update:
Needed more battery capacity for the green.
Another Update:
Hey I just did a bunch of testing with the turning mirror from the PHR sled, and I am sure it will be even better than the PS3 turning mirror!
In comparing the PS3 turning mirror, I get about the same results for red and the blu-ray, but way less for the green.
The green starts out as 95mW's and is only at about 35mW's after the going through the PS3 turning mirror.
So, I have not built my next one yet, but I don't see why the turning mirror from the PHR sled shown in my pictures cannot be used instead of the PS3 turning mirror.
rog8811 has verified that that the only reason he did not try the PHR turning mirror, is that he had accidentally chipped it. So he used a PS3 turning mirror instead...
More testing:
I am anticipating at least 350mW's, maybe 400mW's for the white beam using a GGW 6X at a fairly conservative 180mA's and my 405-G-1 glass lens. And all PHR optics.
I get about a 20% loss through the PHR optics, so this will give me about 180 to 190mW's of blu-ray after optics...
