Default bit of updates..work in progress though...

experimenting with screen.
the one i am using is ordinary cotton, it gave a bluish tint so i painted with white distember . now looking much better and brighter.
but it turned out to be opaque to sound so had to place speakers in front though subwoofers and cetre speaker still remain behind screen.

have a look at the screen size, with me standing.

quite sharp and satisfactory isnt it? (the pics look bit smudged when i resized)
note the projected image is still wider than the screen almost 1 foot on either side is on the wall. (wish i had a wider room)

so far worth the effort..!!

thermocol may be good for reflection but what about sound? it will completely block sound from speakers behind.

collimeter or fresnel for backlight at back of lcd is at 1 inch from lcd.

at front is at 1.25 inch from lcd.(trial and error method further the distance bigger would be projection)

I didn't get?? how it related with sound system, as sound is coming direct from speaker, which sounds quality depends on your cabinet and speakers quality !!

smaller the lcd size better it would for DIY. large lcd ocupies lot of space , need bigger fresnel , more light.
stick with 10inch lcd or smaller with maximum number of pixels anything above 1200pix would be great.
i got a 9inch hd lcd with me "YES PMP900" bought it from chennai. but i did not use it as it does not have video inputs but only reads usb and memory card .
result was great .
