Are Video Projector bulbs robust enough for a simulator

    it used to be that projector bulbs were mechanically fragile, but are the modern ones? Apparently heat kills 90% of the modern bulbs. Have people been successful mounting a projector to the moving part of the platform?.

    I have built a 6' geodesic dome for my 6DOF simulator pod, and with a video projector and a convex mirror, I can have a 60 wrapping display ;-) But so far, it doesn't move, so I don't know if it will survive.

    Thanks,
    Eric

    The risk of imploding bulbs isnt that high imho. Like you said already, heat is the most wearing factor. The bulb itself does not have much mass, so there is not much mass inertia that could crack the bulb.

    Besides that, I dont think that there are any special shock proved beamers on the market.

    Well, you could add some rubber shock absorbers. But they probably would cause to have a jumping picture on the screen.

    Btw, your project sounds intersting. I am curious to see some pics and details soon ;D

    Regards

    Would surprise me if there are any LED projectors with native resolutions higher than 800x600 available so far.

    Hi,
    es gibt schon einen LED Projektor mit 1920 x 1080 mit 600 Lumen.
    Anfang 2010 werden 4 weitere rauskommen.
    Bis dann

    I see no problem in moving a projektor. They have the same discharge lamps as been used in moving heads (i.e. http://www.martin.com/product/product.a ... t=smartmac ). These moving heads make really fast and hard movment and the lamps last the time stated in the data sheets.

    Thanks all!

    Good point on the moving head lamps. I actually have a couple of those and didn't think about it.

    Right now I have the projector on the floor off the far wall, reflecting off of a convex mirror near the center of the floor. Partially, it is on the floor to minimize movement. But I might consider moving the projector to the roof if the bulbs aren't motion sensitive. It gets kinda crowded on the floor, and you need to keep your knees out of the projection path.
