    I'm ready to align my mini RGB. Some advice please.

    Looks great! I assume that since your dichros are fixed, you can adjust the angles of the modules? I imagine that will be a PITA. getting both near and far field alignment is hard enough being able to adjust the lasers and dichros.

    I'm ready to align my mini RGB. Some advice please.

    The red should meet the green at the exact same spot on the dichro, then the blue should meet the green/red at the exact same spot on the next dichro. Most likely your beams will be different sizes, so do your best to center the red and blue over the green. As the green should be going...

    Modulation frequency for Green

    Whats a good modulation frequency for a green with analog modulation. I've looked(here and PL) and can't seem to find a reasonably concrete answer. My current green is modulated by the FlexMod( set to the minimum ~50khz), but the module im looking at is TEC cooled, so I would need to use the...

    Cheap Chinese Lasers

    Research here and on PhotonLexicon. All the components are easily available. As long as you are getting lab type lasers and oem modules, you should have no issues with customs. You can see many designs here and on PL. Keep in mind , that any projector you make will need to be certified in...

    Series or Parallel for two diodes?

    I think(from what I've read on PL), the standard is series with a small balance resistor between them.

    RGB 600mw with 445nm blue, beam pictures and video

    As my projection surface is only 15ft from my projector at the moment, divergence is not really an issue for me. Even with my red and blue focused at the surface, they are both 3-4x larger than my green.

    micro boostdrive vs flexdrive from 18650 driving 445nm LD

    Don't know exactly. But the electrical spec's list the flexdrive as ~10% more efficient and better regulated.

    micro boostdrive vs flexdrive from 18650 driving 445nm LD

    Flexdrive is buck/boost driver. It can lower or raise the voltage as needed.

    AixiZ 445nm lens...

    Got my 2 lenses today, tested them both in my jayrob 18650 host. I get almost exactly the same power from both lenses as I got from the regular aixiz glass lense. They all 3 show the blueish tint. 375mW(glass), 372mW(445), 368mW(445) Pulled my 405 lense from my projector to test, and get...

    Using a PBS from GGW or GBW to combine 445

    Of course thats the most difficult of the GGW cubes to remove, but looks good. Thanks for the info.:thanks:

    Can´t run Half Life 2 on Windows 7 - IT WORKS!

    Re: Can´t run Half Life 2 on Windows 7 try deleting the local content from steam, then having steam reinstall. HL2 is working fine for me in win7

    Andy's massive photo mashup (56k no no)

    Awesome pics. Seems to be a stray red in some of the first pics.

    Help in building a Spirograph

    Unless you are trying to do something like WhiteFusion, pulsing a single laser will just get you dots or dashes, not really a spirograph. I suppose you could have 3 pot controlled motors and also adjust PRF and Pulse width of the laser to create some odd patterns though.

    My take on a quad red

    Maybe blur was the wrong word to use, but I assume without some optics you would see the beams form a pattern like TEM11

    My take on a quad red

    So, double knifeedge(vertical and horizontal) with optics to blur the seperations a bit? What diodes are you using?

    Miss the old DIY red lasers...so I built one

    In the process of making a heatsink to fit my Cree TR-801 so I can mount an LCC in it. BTW just got a email from chuck at aixiz about my 405 lenses.

    XJ-A150 for $1173?

    Re: Xj-a150 $1173? There are also a230, a235, and a145's listed at newegg.

    RGB 600mw with 445nm blue, beam pictures and video

    Do you guys now of a decent $200-300 TEC cooled analog modulated green. My aixiz lab module is giving me a lot of problems even with only 200mW of 445 and 230mw of 650 I can't seem to keep a good white balance. On a simple beam or graphic, its ok, but on more complex frames I get either a blue...

    Building a HeNe...

    hard sealed mirrors will look like this, they can be used for brewster tubes, but may be a little harder to align.
