Floor Projection Mirror Rig System


muff7

Recommended Posts

Hello all,

 

I'm looking to find a supplier for the above projection rig (or something similar..). I've been scouring the net for ages but to no avail. I need to project onto the floor of one of our installations with the projector remaining in the horizontal plane (it's for an interactive floor installation).

 

I've used separate mounts in the past but I'm looking for a slicker solution and low and behold over a burger I saw this beauty!

Any help sourcing would be appreciated.

 

Thanks,

thats a paradigm manufactured mirror rig. We also make a mirror rig to suit the panasonic and indeed any projector. Ours is a bit smaller as the mirror mounts from a single point and can rotate as well as swivel , in theory none of the gubbins are visible from below. Both the Paradigm and Audipak stuff is great and does a fine job and they both make a wide range of problem solvers, but for a lot of installs its a bit chunky and commercial looking thus the need for use to build our own. There is no great engineering challenge here, you just need a adjustable but solid way of mounting optical surface mirror in the right place.

 

its also worth knowing that the panasonic unit pictured can simply be pointed lens down without the mirror. then again its actually not that simple as you need a mount that puts the hanging point above the centre of gravity whilst still attaching at the base only.

Interesting products.

 

On a similar vein, does anyone know if any of these suppliers (or others) do a "twisted periscope" arrangement with 2 mirrors? Like a standard periscope, but with the top mirror rotated 45 degrees, so a normal "landscape" image gets rotated to portrait?

you want to avoid a double mirror if you can as once they get dusty{ and they will} you lose a lot of output. You will also find that the 2nd mirror needs to be remarkably large and therefor costly and unweildy. We could certainly build one, but id be looking at other options first .

 

 

These days as you can mount pretty much any decent projector anywhere on 2 out of three axis, there is no real need for 2 mirrors as either one or none allow any orientation of image. If its portrait on a wall, mount the projector straight down with a mirror pointing either left or right, if portrait on the floor, either point it straight down and rotate the projector untill its in the correct orientation, or use it horizointal with a mirror and rotate the whole assembly. Our units mount the projector and mirror together from a modified unicol gyrolock mount so its a simple matter of rotating the whole unit untill its right. The lens shift takes a bit of getting used to as does navigating the menus, but you soon get your {tilted} head round it.

 

Both casio and panasonic now do officially portrait capable solid state units so they may also be a mirror free option.

I've seen the Paradigm range before but I'm afraid they're priced quite high (>£1000?). We currently make our own (if a bit ramshackle!) for around £400, I'm prepared to pay say £600 if it aids in installation time and ease. Also we are currently use the PT-VX500 which can't be mounted vertically. One of the challenges I'm trying to solve is squeezing as much (throw) out of the projector when there is a relatively low ceiling height.

I made a portrait mirror rig for our XP200s - it cost about £30. :)

Looking at this setup surely there is going to be huge distortion? The nice things about projectors like Epsons ultrawide is the mirror has the built in fiddle factor more or less

an optical mirror causes no distortion, toms rig is to give a portrait image - sothething id like to see done with the epson ultrawide...

 

with respect to the extrusion, the reason we make our own mirror rigs is so as to avoid all that extrusion and offer a single mounting point, The Paeadigm ones are decent, and ive used them before and for rental the are great if you dont have them on show, but they are a bit industrial and offen you dont want to see all the engineering, just the image, all you need to do is have a method of mounting a surface mirror at an adjustable distance from the lens in such a way that you can alter height, tilt and swivel.

Rig the ultrawide at right angles? Its not much dfferent to having the projector in this example point at the floor! We have used the projector pointed at the floor for the last panto and I used it last year onto a gauze at the Palace Theatre in Watford. Any projector will act like a flat screen so ctrl alt and right arrow will give a portrait output
