Try robert.hart@rtpmanhattan.com
Don't know if anyone else owns a Zebra screen. Robert Hart seems to be working on a new screen called "Panther"

Any chance this might work from 7'5'' feet? Projecting on a 100 inch screen.

Also and I don't mean to hijack this thread but are there any ambient light rejecting screens for such distances? None of the ones I keep seeing mentioned seem to work

There has been two days since I have tried contacting Robert Hart by email, Facebook and Google Plus but I got no reply from him. Is there any other way of talking with him?

He replies by email but he does take his time. Just be patient.

Just to give some updates: I bought this Zebra screen last Wednesday and it'll take about 2-3 weeks to deliver here in Brazil. Robert Hart seems very attentive.
I also plan installing an Ambilight-like kit (standalone with Raspberry Pi) behind the screen. Despite the screen having only about 100" in 16:9 format (max size available in this aspect ratio), it'll seem larger because of Ambilight, likely a 115" screen.
I'll post some photos as soon as it's installed.

I believe the research for the Zebra screen was done mainly over at the Home Theater Shack. I can't recall where I saw it over there but it was there somewhere...

Are you sure? Can you give more info about that? I know that he had a thread in the DIY section of this AVS forum.

He posted under the name New Design on this forum, where all of his research is on record. There's no record of anyone named New Design posting on the Home Theater Shack forum.

When Robert posted on HTS, he was quickly berated for his efforts by the Moderators themselves. (...something along the order of "It's been tried before, it's not possible, so why are you bothering us....") Taken aback, he responded to such biased comments, asking simply why they would act so overtly against his ideas and be allowed to insult his efforts, and he was immediately banned by the very person doing the berating. Not so strangely enough, it was that self same person who was banned for life from AVS for insulting the AVS Hierarchy. Go figure.

Intolerance motivated by the Moderators' self imposed aggrandizement, a wholesale lack of support for a new member's ideas, and a double standard that protects the offender if he is a Moderator, and punishes the respondent should he dare question "why" is the reason Robert wound up on AVS.

Robert found a willing audience here on the DIY Screen Forum, and enough support to encourage his efforts. Yes, it's a shame that his efforts could not have produced a application that could easily be "DIY' selfed", but in the end it's the support AVS Community support that did go a long way toward making Robert's effort successful.

This sort of thing has happened before. Several AVS Members got started in Business by working through their ideas on Forum. SMX Screens is a prime example. Of course there exists a fine dividing line between starting out with DIY intentions and crossing over to using the Forum to establish & promote an idea intended to be sold.. Not that it doesn't happen almost continually though. Sometimes, depending upon the subject and individual, it gets overlooked...at other times the intent is so obviously promotional immediate action is taken.

In Robert's case, over the course of several emails I let him know of and be aware of the above dangers well in advance of his final decision to go commercial. It was becoming very obvious the his idea was not going to become a true "DIY" reality and so being, he did the right thing and pulled out of active Forum posting. As such, due credit and a good degree of confidence can be attached to both him and his efforts.

But....the DIY effort toward such a screen has not died! The research and efforts go on in Robert's (New Design) Thread by others determined to do something similar for less expense. Will they succeed? They very well might.

Hey guys I'm a new member but a long time reader of this forum. I just thought I'd sign up to share a bit of info, unethical as it may be I think a black screen should be something that a diyer should be able to slap together without paying a ton of money. I found the zebra screen on ebay for sale the seller was roberthart******. I did some digging thru his feedback and found he had purchased "´╗┐Window Tint Film 2 PLY Professional Roll 60"x50ft Tinting 50% VLT" item # 181324915933. I think that it should be safe to say that since it is being bought in bulk and so big, that this isn't for product testing, it is most likely being used to create the screens. Like I said unethical or not there it is for those of you brilliant diyers who love to tinker and don't have wives to stop you from doing so.

Last I seem to remember read about his work, was that he was looking at a reflective base material + window tin+ defuser and was then tryin to find best way of sticking them all together without getting bubbles and losing image quality.

That's exactly what I remember. I believe he reached the conclusion that he couldn't create the "sandwich" without expensive production equipment beyond the means of a typical DIYer, and that's when he decided to turn it into a commercial project. So even if a DIYer knew exactly what materials were being used, proper integration would be the limiting factor on creating a quality finished product.

............and yet there still exists a distinct possibility of doing exactly that. Some AVS oriented experiments are ongoing, and if they bear fruit, they will provide a way to create the sandwich.

As to if the exact materials in use with the current product would be revealed....that remains as best problematical. But at least such an advance would not rule out similar experimentation.

Well what do you guys think of this for an idea of sticking the layers together: when making car windshields and bullet proof glass they fuse several of glass together using paper that turns to invisible adhesive once heated up. If we could get our hands on some of that adhesive it maybe possible rig up the appropriate layers (in there rolls) on the wall and pull them onto an empty roll with the adhesive in between the layers and heat up the layers on the new roll with a heat gun as it spins. Sorry for the bad explanation hopefully this bad picture will explain things better.

Well for that matter all the materials needed should come with adhesive once the backing paper is removed correct? So bear with me on this one. What if the first reflective layer is applied to a big piece of glass (or any smooth glass like surface should work the same) but don't pull the backing film so it doesn't adhere to the surface permanently. Once it is all nice and smooth apply the tint layers to the reflective layers like you would when tinting a window using the adhesive and soapy water to apply. once the tint layers are on, then the diffuser goes on the same way, once cured for a day or so in the sun light you should be able to pull all the layers off the glass (or smooth surface) at once and have a perfectly bonded multi-layered sheet. "F*** YOU SCIENCE!"

MississippiMan, I should have added at the end of my last post what I was thinking -- that DIYers can be clever, resourceful and persistent, and just because Robert couldn't find a DIY solution doesn't mean that others will (or should) give up.

frozen-hampster, you should post your ideas in the DIY black screen tests thread in the DIY screen forum, where lots of brain-storming and experimentation is being discussed.
