DIY Video Projector - Page 147

hi guys,

Just surfing around looking for panels today and found this:

http://www.prokia.com/pj/engine.htm

Looks as though one could buy the 'guts' of an XGA projection minus the lamp assembly and heat sheilding.
I emailed their sales department asking about availability and cost- if/when they email me back I will post their response here.

Wow, that projector engine seems really cool, put a nice plexiglass case around it....

I couldn't resist the urge and I emailed them too. It didn't occur to me till afterwards that maybe we shouldn't flood there email boxes with our single order requests, we don't even know if they would take orders like that. From the looks of the we site, they are a fairly sizeble company (a joint venture with Viewsonic) If the deal with Viewsonic is anything like the deals Sony makes with its suppliers, there is no way in hell there going to sell outside of Viewsonic, let alone to individual people in the states.
But I can only hope

Wonder how much those things costs....?

BTW, Hey jjasniew, did you get my email? I'm not sure if I wrote to the right email address. I want to buy some of your stuff you may have left over. My email is mikepri97@aol.com

Check out http://cgi.ebay.com/ws/eBayISAPI.dll...tem=1725801053

It just may be the lens you're looking for (although doesnt come cheap, I see)

I'm willing to sell some panels. My email is joejas@ihpc.net.

I'd like to point out that I got killed (near total loss...) on a couple of them, so, I'll have to price them reasonably (In other words, I'm not takin a beating no mo'!)

I guess the benefit to anyone interested is that you'd have an exclusive opportunity - w/o the hassle of being upstaged at the last minute. I've offered one panel to a member here earlier today, after seein him get stepped all over on something he was interested in on ebay.

Commenting on the nice pictures on e-bay; well, my pictures are nice too! And it's the *camera* and whatever processing it does when it takes the pictures that account for a substantial part of how well the images appear. They do look pretty good for a 1.4M color panel.

gotta run...

Hey guys great news! I got mine up and running. Im using a sharp qa-1150 with a 3m (model 213) overhead projector. When i play dreamcast on it through vga it is spectacular! But when i watch tv, play xbox, or watch dvds (through composite) it is kinda lacking, but still very nice. The main problem with composite is that all the colors look kinda faded, though with vga the colours are bright, vibrant and crisp. Im thinking of buying a vga converter so that everything will be as nice as dreamcast. Here's the one im thinking of getting:

I will post pics soon!

bodysuitman,

i use a vga adapter called the aimslab jam. It is cheaper than the one you want on ebay, and IMO it works better (i have used both)try looking for the jam on ebay, you should be able to find it for about $20.

regards,
Aaron (the proud new owner of a sharp qa-1500)

ME OMG it works!! $50 for OHP a bad *** one and $150 for good lcd panel and i got a 7 foot wide screen the screen is just a white king size bed sheet i havent painted it yet im going to try some of this reflective paint and see how it works. the pic of the screen dont do the real thing justice it looks bad *** if you are up a few feet from the screen you can see the pixles.

yes thats 7 foot from side to side.

BodySuitMan · 26th April 2002, 06:20 AM

Snoogans, thanks a lot for the info! I will definately look into that cause damn, tv, xbox and anything else on composite looks almost black and white, but vga signals look beautiful. Have you noticed this on yours? Does this aimslab jam make the colours better as well as clarity? Thanks a lot!

is this the right thing?:

snoogans · 26th April 2002, 07:30 AM

bodysuitman,
that's the right one, it produces clear signals, but you might be able to get it cheaper than that auction. I got mine for $19 at half.com.

Regards,
Aaron

I measured them with my meter and they are both rock-steady.
Maybe you have a bad power supply?
