    If you mean the VGA connector then that can be found at any local radio shack or any electronic parts store.

    What do you mean with vga setup?. If you mean the VGA connector It is called "D-sub 15-pin connector" And as kbates666 says, it can be found at any local radio shack or any electronic parts store. But the connector I'm using , comes from the VGA kable that came with the screen. I cut away the surrounding plastic of the cable and attached the connector to the case. If you can't find any place to buy the connector you could always use a VGA extension cable and cut it out like i did.

    Was gona post a new update today but I forgot my digicam in the workshop :wallbash: .... and it's a 30min walk to get there. So it will have to whait fo tomorrow.

    This is what I have been doing lately..

    This is the buttons for the tft controlls. Its a 7mm steel rod from an old printer.

    (CLICK TO ZOOM)

    After putting them in the drillpress and smothing them with a file and 80-120-240-800grit sandpaper. They look like this. The surface is so reflective it was hard to get a good capture of the true look. They look dirty but they are not.

    Stole some pens from my mum and took the springs out

    When pushing the buttons, the springs will push the buttons back. I can adjust the buttons to be even with the front surface later, by screwing the M3 screws in or out. The electronical parts of the buttons will be added in the end.

    Mounting plate on the backside of the front panel.

    Buttons mounted.

    To get the holes for the buttons lined up correctly I taped this PCB card to the plastic front and drilled every 7th hole using a 1mm drill.
    [​IMG]
    (CLICK TO ZOOM)

    The holes where perfectly aligned. Here I have used a 3 mm drill to enlarge the holes a little bit to get a better aim with the drillpress when heading on to the big 12mm and the 7 mm drills.
    [​IMG]
    (CLICK TO ZOOM)

    Here is a sneek peak of the front. Still need to fabricate the 12mm main power button. But so far, I am more than satisfied.

    (CLICK TO ZOOM)


    On with the zoom mechanism.

    This was the first method i was working on.. I spent alot of hard work trying to get the design to work, but it was to hard. Hardest part was to get the holes in the plastic to align perfect with the metal rods. IN the end..it turned out very wiggly or it was totaly jamed. I don't want to think about how many hours I have wasted on the zoom mechanism design, but I'm shure its more than 25hours of head scratching.
    [​IMG]
    (CLICK TO ZOOM)

    I have seen people use these type of sliding rails in other projectors but I didn't think they would work any good. They look so wiggly and unstable. But when I found one of these laying around in a shop nearby it blew my mind. It was just the perfect thing, very firm and stable in the sliding. How could I bee so stupid to doubt on these things.

    Attaching the sliding part to the bottom of the lens holder..

    (CLICK TO ZOOM)

    ...and the sliding part and the rail together. The zoom mechanism is done and it slides great and is very stable.. [​IMG]

    Now I need to attach it to the case bottom...but that's another story ;)

    Nice Zoom, I also would have thought that the rails were unstable but obviously I was wrong.

    Nice work

    I need some advise on the finishing touches of the buttons. I am thinking of using my sandblaster tool to create symbols on each button.
    These are the symbols I'm thinking of:

    [​IMG]
    POWER -------- MENU -------- LEFT -------- RIGHT

    I made a test, with one spare button I had laying around. It's hard to show on the photo but the symbol has very sharp edges and it's sandblasted into the surface and will not come of.
    [​IMG]
    (CLICK TO ZOOM)

    Don't care about the surrounding material. It was just an alu rod with a hole in that the button fitted nicely in.
    [​IMG]
    (CLICK TO ZOOM)

    This is how they look at the moment. Simple and clean without any symbols.

    What do you think....???
    With the symbols or without??

    Please post what you think.....

    Personally, I think the symbols add a nice touch to the already beautiful buttons. I really like the look

    without, it looks so clean, and original, the symbols can be seen on every amp or cd-player, electronical stuff, this clean and it runs in with the brushed aluminium, if you sand them it ruin the balance

    I think just having the symbols on there with nothing else would look pretty slick.

    I vote for no symbols on the buttons. Why not try a mock up of symbols on the black plate?

    i probably would put some simple, black symbols on the buttons, otherwise no-one except you will understand the projector

    small pics can be very subtle

    I like the sandblasted, simple symbols. They add a simple elegance, and don't look cheesy or stock at all in the very classy and well crafted way you plan to install them. I disagree with the idea of symbols on the backplate, as I think it would kill the brused alluminum look (sorry wahoom, it was a nifty thought, I just don't think it quite fits iwth this mod).

    Oh, and I would do something slightly different for power, as that's also the record symbol. I think the I/O symbol would be too complex,and kill the simplicity though. What about a square diamond? or some other simple shape. an upward pointing triagle?

    The buttons will rotate from use, I'd put the symbols on the backplate.

    The traditional power button stems from 1 + 0, binary representation of on and off.

    hey OP I have been following this pretty closely but what do I need to make my own like yours since I already have a MAG 15" LCD monitor. Can I just get a cheap overhead projector and use those parts? I was also wondering what 3d software did you use? Thanks
