I was already frustrated as i cannot get the clearer shot. And i just realized that at the end of the first dvd of freestyle they will change dvd and image will stop at dvd menu. the customer specifically requested beyonce.

I told my brother that image will be alot better if he will remove the protective glass.

When i showed it to my sister in law, she made me laugh very hard.

She said that other people may anylyzed the pics as like there is billboard on the roof!

Ha!ha!ha!

Will come back later again and will try to come at 5pm while they ares till close.

The image is just shockingly huge. My brother told me that one cutomer ask if it is a heavy duty cinema projector and he just laugh!

Next project for him is projector in his VIP room/Home theater/karaoke for customer. This is alot easy to do as projected image size is only 120 inches diagonal.

Maybe some keystone adjustment controls can be figured into the design?

Or is there some software that can mimic those adjustments?

cool.

so the smaller lcd that is being used the sharper the image?

No. Image sharpness depends on the focus of the lenses aiming the light against the LCD screen and the relative resolution of the LCD itself.

the smallest 1080p lcd is 15.4 inches
smallest 720p lcd is 6.3 inches

Cant decide yet what to build next. 1080p is kinda exciting bec 1080p projector cost more than 100t pesos. Looking at 20t budget to build this 1080p projector. I need to build one more for my brother in law.

two ways to adjust keystone.
1. lens shifting- moving the field fresnel off center
2. tilting the field fresnel.

If you are using pc, nvidia has keystone correction included in their latest driver for their latest model video card.
