    Default Projector Help

    Hi,

    I am new to this forum but have been reading it alot over the years.

    I really want to get into projection mapping but don't really have any front garden to project from.

    I have been looking at short throw projectors with a mount that i can fix to the top of the house that will come out a bit.

    I know i wont be able to do a full projection mapping of the house but would at least like to try some of the house

    Does anyone know of any ultra short throw projectors? I'd obviously like to cover as much space as possible.

    Thanks

    Chris

    I don't think there is any projector you can mount on your house and project onto it. You need it out front. One person had it across the street in the neighbors house but most build a box or sink a pole to mount a box on. So figure out how far from the house it will mount, farther the better for area coverage, however you lose brightness. Shop for a projector that will do the width you want at the feet away your going to mount it. And you will probably want at least 3000 lumins.

    Thanks for the reply. Unfortunately i don't think my neighbors would let me project from there place. I was thinking of one of these Classroom-Education-Business-Aluminium-Universal-Adjustable-Length-870mm-1500mm-LCD-DLP-Short-Th.jpg (high up outside the house) and looking for a short throw projector which can do the biggest image. Do you think this would work?

    If you want to buy a very spendy short throw and have about a 8x10 projection on the house that would work. But I don't think that is what you had in mind.

    I live in a estate and a lot of the houses don't have front gardens. I was hoping something like the above (bracket) would work for projection mapping on some of the house.

    It might be that i need 2 to get the width. (approx 5 meters). See attached picture of house layout. The blue is the projector/projection (not to scale) i am hoping it would work like this.?

    Any help would be appreciated.

    Link to a reasonably up to date database of short-throw projectors.

    You don't need a garden to hide the projector, and here are links to pictures of various enclosures you can buy or make:

    https://www.google.com/url?sa=i&rct=...54590162993706
    https://www.google.com/search?q=proj...BOLJhDyUTnM%3A
    https://www.google.com/search?q=proj...WblaA2_gE4M%3A
    https://www.google.com/url?sa=i&rct=...54590162993706
    https://www.google.com/url?sa=i&rct=...54590162993706

    ... and so on.

    Here's another website that might be helpful to you: http://projection-mapping.org/perfec...ng-projectors/ and I gave you that link for the obvious reason but there was a specific paragraph you might be interested in which reads: "For instance, with one our recommended projectors, the InFocus IN122ST, the projector can display a 10 ft wide image at only 6 ft away from the object. (Pro tip: check out ProjectorCentral’s projector calculator, which can calculate the image size for any projector distance.)"

    Again, you don't need a garden. All you need is a bit of yard, and an enclosure. I haven't done projection myself but it's on my list for a couple years down the road and even though I have bushes and plants bordering the street, I'll be putting my projector on a pole, and an enclosure on that pole, to ensure it doesn't get misaligned, protect it from vandalism and theft, and the weather.

    Hope that helps.

    I assume by no garden, you mean no front yard. But even a small yard to get that projector 10ft to 15ft out would help alot plus getting a straighter angle to the house. Might be able to squeeze the whole house in. Your picture does a good example of what to expect with only 5ft pole off the peak, plus the angle to the bottom of the picture is steep. The link above to Projector Central is good, you select a projector and you can slide the bar to different distance to see the effect on specs.

    You might be able to make a custom 15ft bracket that angles down 5ft and cover the house. But it would take some good planning. Let us know what you do, as many people are wanting to go with projection mapping.

    Depending on your budget you could get the following projector. It is an ultra-short throw projector and at 4 ft from your house you get an image that is 9ft high and 16 ft wide. It is 4000 lumens but better yet at this distance your FL rating is 14 which is in the ideal range for a darkened room. Ideal comfort range runs from 12 to 22 FL. This projector just came out this past July and runs $1600.

    depending on your distances, there are quite a few Ultra Short Throw projectors that are intended for use on classroom smart boards. We had one that would do about a 100" diagonal image from about 13" off the wall. Of course there is some falloff as you get to the corners, but thats the trade off..
