Building your own projection tv

[Spicker]

it's a great thread, before it was posted, i never even knew people did this, the box design atleast, i had heard of overhead projectors, but the quality wasnt as good. yellow treasures results are astounding, one can wish, while others turn wishes to reality.

yea thats what inspired me...

the quality is just amazing....

did you happen to see jaymans? it's crystal clear, unbelievably 5th element looks even crisper on his. the results they are getting with 5" is crazy, it's not as big as the others but still nice for such a small size and limited pixels.

good news...i will be ordering the parts when i get my lcd...and i bought membership@LL

been doing a little reading..and the more i read the more confused i get

one of concern's is that i dont have a router(to cut wood and stuff) so i cant do alot of wood wokring unless i rent from home depot.

second, how am i going to hold the lenses and lcd in the box?
i was thinking about this way:


u can supposebly get them at lowes

also im little confused about the wiring and i need to draw wiring system...

i want a switch for the LCD, switch for bulb/ballast and a switch for Case Fan(s).

what resistors and stuff would i need? (btw im going to be using the eballast)

well i found some wiring diagrams...

and i decided to use a switch instead of a thermostat for the fans...so ill manually leave them on after using it....etc.

wiring diagrams:



EDIT: one quick question... 1000MA=how many amps??

So far, with the exception of gepper's pics, the rest are taken from the LL site. Those are pics of what the people there have done

I'm with Spicker, the more I read, the more confused I get.

Of course, I could just follow the basic, but I want it to be great

Also, the more I read, the more features I want to add: key-stoning, decay timer for fans, delay ballast timer to protect the bulb, temp probes, temp alarms, bla, bla, bla....

Well, a Varifocal Projection Lens allows you to fine-focus your image simply by rotating the lens barrel. Otherwise, the distance from the lens to the screen will fall within a certain range when you use a Triplet lens. Key-stoning allows you to hang the projector on the ceiling (or floor) and adjust the image not perpendicular to the projection path.

how much better does splitting the fresnal make the picture quality?
