    Cool >.5W RGBV projector

    It is not in a finished state, but it is together and producing some nice colors. With the help of Pangolin's extra color channels and the ability to fully tweak the color settings, I got what I feel is a true purple. I have always loved purple and though blue magenta was a poor equivalent... I ran a pair of wires off the 5th color channel and dubbed it violet.

    I am using a reflect UV, pass all that I got from Mario Master to mix the 405. I have Bridge's dichro, but it is real thin and the dichro holder... won't hold it. I was in a hurry and saw that and grabbed it up. Based on "eye" tests, it is actually a bit more efficient than the dichro at the angles I have available in the projector. Once I have a meter on hand I plan on testing the loss on both of them. There is a fair amount of white loss and 405 pass thru on both unless they are at very severe angles. If you see in the pictures below, I go across the projector output to a mirror before going to the dichro at a 20 to 30 degree angle. Interestingly the sweet spot for both white transmission and UV reflection seem to be very close. I still want to check with a meter.

    Most are somewhat familiar with the heavy beast, here are some shots of it with the addition of 140mW (after cube) 405nm set up. Right now it is running with:
    140mW 405 daedal wdie4drives+, 4x@75mW, 6x@100mW, 140 after cube
    100mW 473 Laser Wave
    100mW 532 CNI
    300mW 660 MechEng3 wFlexmods, 2x175mW, 300 after cube

















    Love, peace, and grease,

    Truly bitchin' Purple, Aaron... lemme see if I can get us hooked-up with a gig for 'Prince' we can go 50/50, cool?

    And great color-palette - that last 'cones' shot is quite 'eyegasmic'...

    I'd forgotten quite how good that "plasma orb in a box" sequence is.
    Great photo's.

    Sweeeet purple!!
    I think I had a great idea yesterday when I ordered two 405nm diodes
    Can't wait to receive them and install into my projector (along with another two extra 660nm diodes, damn that means 1.7W in theory )

    Very nice!
    I'm going to attempt something similar in the next few months,
    Where did you get those small x/y mounts?
