just tryin to make sure i got this right, the front of my lcd (part you look at normally) needs to face the light? and thats it right?



also im pretty sure im goin to use the gravity keystone for my front fres, so i will make some kind of wood notches like i seen other people do and hang it with a rod, i guess with clips or something, but my rear fres should b exact and the light should b adjustable correct?


one other question, i bought a fan from frys with a thermal sensor in it that adjusts fan speed, only problem its 12v. any ideas? take it back? etc

LCD needs to upside down, and the part that you look at needs to face the light. Yes, your rear fresnel needs to be at a 90 degree and and center with the bulb, LCD, and front fresnel. What do you mean there sa problem that its 12V? Almost all computer fans are 12V, its the standard.

Make everything adjustable so you can optimize the projector after you get it working. You'll regret it later if you don't.

ok then i think i have a problem b/c of the way my circuit board connects, how do i mouth the lcd upside down when all my controller stuff connects to the bottom of the lcd?

see where it connects? that is normally the bottom of my lcd so that would have to b up in the air for me to mount it upside down. this make sense?

diy guy i think im a complete idiot, i meant to mark the diretcion of hte lcd as i was stripping, so where those connections are may have actually been the "TOP" of the lcd wich would b ok if i have to put it upside down, i need to power it up and check that it works still anways, ill then get the orientation right

also on the fan, even though im an electrician it threw me, i though some guys where gettin 120v 120mm fans, sorry im not used to computer stuff, i do commercial electrical.... so now i guess i need a dc voltage adapter or something? time to hit frys up again


and yea jon im tryin to make everything adjustable, the next big step in my plog is building frames for lcd and fres, to where i can move them around. any ideas

LCD's come in a variety of designs, and yours may very well be that the board was originally on the bottom, even though that is not as common is it being on top. If it is, just simply plan out your box to fit that board and LCD.

what i'd do is cut up a bulletin board and put it along the sides inside the PJ. hold your fresnels/lexan/lcd in place with push pins. frames are optional with this but i would encourage them to prevent potential warping. this method also makes it super easy to adjust everything.

pretty good idea, ill try it out to get positioning right

Most LCDs have the electronic panel attach at the top.

I always state it this way. If you look at the panel through the hole where your lens is going to sit, the image should appear to be mirror imaged, and upside down.

Upside down, because the lens will rotate the image 180 degrees as it focuses the projection on the screen.

Mirror imaged, because the screen itself acts as a mirror, reflecting hte focused projection back towards the seating position.

DAZZZLA came up with these pictorial representations:

A standard straight projector:

Lcd Orientation - http://www.lumenlab.com/forums/index.php?showtopic=23860

thanks those help alot! and yea i forgot the orientation of my lcd when i was stripping it, where the connections are it is infact the top wich will now b the bottom

also should i b putting silicone on those connections like everyone else to help strengthen them

Its free insurance

where are you guys gettin a ac to dc adapter for cheap that i can just splice the wires to the fan? i went to frys and only stuff they had was those huge power strips for your car and the cigarette lighter stuff.....

r a d i o s h a c k

gotcha, guess i just get one of those plug in adapter kind and ill just splice with that...

im having alot of trouble building the frames or some way of holding the lcd, and fresnels, i dont have a router and im not that great at woodworking..
