Urban JungleBoy wants it.

Subjecting friends to bad movies splattered all the way across the hotel room wall... priceless!

Wants it bad!

It's a bit big to haul to conventions.

The pre-made $499 one?

That's only 640x480 native, it interpolates higher resolutions down.

The concept is pretty cool, but there is no keystone control on the DIY ones. For $500, the pre-fab ones seem to be the way to go too.

Oh, if only I had time, projectors all around!

Yeah, I was thinking keystone would be a problem on the homebuilt projectors.

My optics knowledge is crap, but I was thinking if there was a way to mechanically adjust the keystone I expect that they would have designed that into the box plans.

Just looked at the PDF; it is possible to adjust keystone, and wouldn't be too difficult to mount the front fresnel lens in a pivoting mount...

Ahh, you're one up on me. I haven't looked at the PDF yet.

But, I was wondering if you could put two bulbs in there with a massive cooling system to up the luimens and make it a force to be rekoned with. Perhaps lining the inside with a silver metallic material like foil or that metal insulation tape would help too.

I think this thing is sooooo rad. Now it's even more tempting.

The forums have all sorts of different implementations detailed.

This vertical projector is probably the most elegant design. It has fixed keystoning (it's designed to be an "installation" unit)

I don't think a 2-bulb design is feasable. Check out this 1000w bulb project in progress.

The Art Deco Lightgate is also really impressive, and has "gravity keystoning."

Thanks for posting this - I've just passed that link on to the heads of Programming for TT - getting enough projectors is always a pain. (This weekend we spent nearly as much as that one costs just to rent one for Saturday - though that was in Canadian dollars.)

We might be able to find a cheaper one around here, but you never know. I'd heard that they were currently available from some place (Home Depot, perhaps it was?) for C$600, which at current exchange rates is roughly US$540. Though when you add the sales taxes, it's nearly $700.
