    Default First RGB

    Hi All,
    Just started on my first RGB!
    I am using an od desktop PC case as the enclosure.
    I figured as long as the optics and lasers are mounted seperately on a rigid base plate I will be OK.
    You can see the general layout in the attached pics - with a gap for the red I won in the Cruch raffle! Next to it is the 50mw blue, also from LaserWave.
    The scanners are te Scanpro 20's.
    Will add more as I go along.
    Any comments/suggestions/questions very welcome.
    All the best, David

    Looks good.. I'm suprised more people don't do this.
    You end up with a metal case (good cooling) and a nice looking product.

    The rigid base plate is real essential for RGB you dont want things moving flexing etc.
    I used 8mm ali' some I see use 10mm..

    One trick is to run a couple of heavy , like 6mm L shape stiffeners along the back of your mounting plate. This ensures a flat plate and less tendency to warp and flex. I did this on mine.

    Keep the pix coming as you build it up..

    Cheers

    Thumbs up

    Looking good man! My second attempt at a projector was done in a Gateway 333 case. Looks almost exactly like the one you are using. You are using a better layout.

    hi David

    lookin good ... is that the DMX board from lasershow parts ... ?

    i like the idea of the folds on the back plate .... ive just used a standard flat 19" rack plate ... and it flexes every time i plug in and out

    bet you cant wait for the red ....

    all the best buddy

    Hi Karl,
    Yes, that is the Lasershow parts DMX board.
    That back plate is a recycled blanking panel from work - as you say the folds do make it more rigid.
    Yes - certainly looking forward to getting the red, but plenty more to keep me occupied in the mean time.
    All the best, David

    ey david,

    Nice work..!!
    Are you sure that allubase "plate" is thick enough?

    Is your DAC arrived yet? (lets see some grafix :-)

    Just had a message from Brigde. He asked if I would like the beam height of the red to match the blue (it is normally about 5mm lower)
    There's service for you! It will take a bit longer, but worth the wait I think.
    He also askes if a beam height of 29mm for all would be good - any thoughts?

    Anthony - Base Plate, yes I know it does not look very thick, but it is supported by two ali "U" sections - and I will probably add another down the centre.

    Dac- not so good news there. Ordered Moncha Lite - almost a month ago -appears it has got lost in the post somewhere Micheal from Showtacle has started an investigation his end (it appears it never actually reached the UK) and has promised I will get a eplacement eventually.
    All the best, David

    Looking good. I see you are running green, blue, red with your dicros. The 15 mm ones I have from Bridge are Green, Red, Blue. He must have two different dicro sets for RGB.

    Hi Mike,
    I have the older dichro's - on Robs UK laserwave site they are called GB and GBR types - maybe you have the more recent RGB one?
    Looks as though we are both at about the same stage at the moment, though I might not get my red until early October.
    I am so looking forward to seeing it workin, but I am determined not to rush things.
    All the best, David
