I was planning on doing the 15" Vertical design and cant wrap my mind around a few things..... but anyway isnt that the story with everyone. I would like to see some inside pics of the vertical design so I can better understand some of what is needed.

For example..

keystoning with the front fresnel...

The circuitry falls down toward the lamp correct?

Pics of cooling path over LCD... is this effected much by the LCD circuit boards?

Since the LCD circuit boards are toward the lamp, how to protect them from heat? Aluminum flashing to prevent direct heat but will this be enough with hot air in the enclosure?

If the front fresnel is adjusted for keystoning do you need to adjust the mirror angle at all or will this remain the same (I assume it will)?

Hi,nintari!
For some pics of airflow diagrams,and keystone and circuitry,peruse my plog #1.
The LCD circuitry would naturally face down towards the lamp,but I found that mine( a benq 567v2) was perfectly happy to be coaxed into an upward facing position without any problems.
Mirror angle will only affect the height of the image off the floor,and will normally stay the same,otherwise the triplet needs moving too.The higher you have the image off the floor,the more keystone will be needed,but the more keystone you use,the more out of focus the top and bottom will be in relationship with the centre of the image.
Hope that helps
Cheers P

ahh it helped some I had looked many times at it, sadly though my skills as a builder will not be close to what you have designed I am not worth to copy your design hehe

What I was looking at doing was making the LCD, and fresnel frames from 1/2" MDF that I can just slie in to place...have square dowels as the holders on each side of the enclosure. This would really simplify things for me and my limited skills lol. I figure as long as I stay in close specs anythign I do should be better than what I have as right now I am not aligned properly, but amazingly it all still looks great lol.

I was thinking though for the top fresnel keystone to have a central pivot point for the keystone adjustment. This would hopefully be a matter of balance for adjustment.

I thnk I will only need 5-10degrees of adjustment so not too much to worry about. However depending on how things work out I may be able to place the projector behind me and have the lens centered behind me, get a bigger screen and have it a high power screen... all depends on how the build comes out

I went with a 15" vertical also.

For the top fresnel, I used quarter-inch dowels in the front and back. The back dowel is fixed in place, and the front dowel is adjustable up-and-down. As a quick test, I used push pins as the supports for the dowels. They worked great and I haven't replaced them yet.

you have a plog mud?

Unfortunately, no plog. We were without a digital camera during the build. We have one now, I will try to get some pix when I am home for a stretch. I've been travelling for work quite a bit in the past 4 months.
