    Default Lunch anyone. Build

    This build will be a full laser show in a lunch box. Using a iphone, DZ board and the methods he recently posted. As well as a 3W projector just bummed I haven't figured out how to add spacial filtering. If I can fin the optics to do it rgb I'll put it in the final path. My existing lens don't bring the beams to the same focal point.
    I plan to upgrade the lunch box to a pink Floyd.
    Here is the test layout. Also it will be capable of 120AC or 12V for power

    This is awesome so tiny and compact. Can't wait to see output.

    Love it, what diodes are you using?

    Dupe...

    Diode are Mits 638 will be over driven to 800mw after correction, 9 462 and 520.

    Let the drilling begin, also for those who might have jumped on these $2 power supplies the one heat sink it able to be tapped for a vertical mount. If you do this be sure to isolate it from the baseplate. I used nylon screws and kapton. Heavy vibration might cause some solder joint issues but that shouldn't be a worry in this build. I could have used some L brackets but this is cleaner. Click image for larger version.

    Sweet! So what's the plan when its complete? Photon lunch days?

    The switch to a PF box will be cool, but if you can't find one, I suppose a unicorn would be an easy to find alternative!

    The holes are now all tapped. Wow the quality of box house taps has gotten pretty bad. Broke off 3 and spent way to much time removing them.
    Next I'll be swapping diode housings to some of I believe Bbe's red centering is awesome and I'll use his 9mm to just make beam heights all even. I also have switch to his drivers. Big thumbs up on them.

    Think I found room for the spatial filter, just have to research the best lens and defocus if needed at the diode.

    Acromats work but triplets work better.

    NICE !!! Ten pounds of you know...ina Eight pound box !!!...Looks like LSP C-lenses !
    .
    Are you using the NUBM's for the Blue and Green? I wonder if you can cram the Spatial Filter in the Box ??

    Well I have a beam path. I'll be happy if I can get the spatial filter working otherwise I'll drop this to single mode. Some ugliness on the final dot as expectedClick image for larger version.
