    Mini LED Projector

    mods, if this is better suited to the lcd/display, feel free to move.

    so i am starting to see these mini led projectors all over the place, and they are starting to get to the point of a reasonable hobbyist cost. like this one for $160:

    has anyone tried one, and how well do they work?

    with a native res. of 640x480, i can't imagine they are amazing, but do they suffice for a large, standard def. screen?


    every time i see one, i start gett ideas for a portable theater/carputer project...

    I saw 3 different manufacturers at CES....quality wise there all pretty good and very impressive for their size but they all still need a dark room (dispite what the advertising might say) for anything other then a washed out presentation

    I saw several at CES. Kinda neat for sharing pics of the kids with family or a couple of snapshots here and there. Pretty useless in anything except a very dark room. The low power light source and lens size really hinder this from being usable as a viideo display device.

    It strikes me that this would have a VERY high geewhiz factor the first time you used it, but you would become very quickly dissatified with the picture quality and ambient light limitations.

    Just an opinion, YMMV.

    Here are some comparisons to my high definition home theater projector.

    Contrast ratio: 100:1
    Screen size: 20 ~ 50 inches
    Projection distance: 1.31 ~ 6.56 feet (0.4 ~ 2 meters)
    Brightness: 15 (about 210 ANSI lumen)

    The contrast ratio on my projector at home is 3000:1, the more the better. This is how far the blacks are from the whites so with 100:1 you're going to get a lot of washing and the blacks are going to be gray at best.
    The screen size is very small, most people have televisions way over 20/30/40 inches.
    Projection distance is less than 7 feet. That's like lying down on the floor with the projector at your feet and screen just above your head. Pretty short.
    And my projector is 2800 lumens, I can barely watch a dark movie with the blinds closed in my house, this little projector is 210 lumens. Unless it is absolutely dark, you won't be able to use it. I mean even moonlight is going to wash this thing out.

    These mini LED projectors, would they make a decent HUD for a vehicle ?

    Yes. At night in the garage with the lights off.

    You could just get an arm to raise a screen from the front bumperbar.

    Alas HUDs are generally an angled projection with compensation for the angle, as well as screen curvature. (Then there's the 3-D or "behind the (wind)screen" effects.)

    they're not THAT bad if you don't expect a lot from it. I have the aaxa p1 which is a 12 lumen handheld unit similar to this one. It washes out in light but with dim lighting, it works out. Its good in the dark. http://www.aaxatech.com/products/kp1..._projector.htm

    I bought mine as more of a toy gadget than to actually use for in-the-light use.

    this pic is with the lights on in the house. the lights are a little dimmed but you can tell how much it washes out - still usable for fun though.


    I can take more pics and review it later.
