This is the projector I built.

Parts:
-12.1 lcd kit from Johnzo
-220/320 fresnels
-320mm Triplet
-Electrical stuff
-Box made of 1/2" MDF
Overall dimensions: 27.75 x 12.125 x 13.3125 Inches

You can't tell very well from first pictures but everything has a groove that it fits into. The frames for the lcd and rear fresnel are made from wood and also slide into grooves cut into the mdf.



Here are the first pictures of my box

One thing I do know is if you want to work with MDF make sure you are wearing a mask and consider getting an air filtering system. The dust is fine and it is everywhere.

This is the fan hole I cut in the back panel as well as my practice for cutting out a pentagon for the focus ring.

This is how I fit the focus ring into the front panel and also the air vent holes I routed on the bottom which will bring air into the bottom chamber, up between the lcd and rear fresnel, and then back down to the bottom compartment where the cage fan blows it out the back. This should ideally cool everything





This is my super amazing idea for front keystoning, I'm going to use these hook things I found. The rods fit right in all the slots and this makes it super easy. I was just about to have a hard time making the slots because I don't have a drill press when I saw these laying around.

.

Here is my fan filter. I put a piece of fan filter material between the frame and the front grooves and then use the cams to secure it in place.



This is my faceplate I hand cut. Since I'm sucking air in from the front I don't want air coming in through the controller port so I had to find a way to seal it off from air.

Here is my finished bottom compartment.

Here is my finished top compartment and my lcd in it's frame.

Here are some screens projecting on a yellowish wall. No tweaks done to the panel settings.









So now it's done. Great Success.

sweeeet! what did you use for your light engine?

thanks..

I am using this bulb with a reflector: http://www.bulbconnection.com/ViewItem/bcr...2F942/item.html

Any more questions please ask.

the white looks pretty good using a 4200K bulb are you happy with the brightness of the 150w'r

whats that line on the right side?

Yes the white is very good.

It isn't super bright but yes I'm happy with it. My fan thermostat hasn't even been kicking on so it doesn't make that much heat. I feel that if I find money to buy a screen it will be even brighter. The problem is I need a 150" screen and those are really expensive. But also I can black out the room easily (I tape blackout cloth over the windows) so it works fine.

Congrats F2a, nice and clean build. Have you painted it yet or are you still working on the finish? Nice set of tools used btw

I was thinking of painting it black but decided against it. Down the road I might make another box so then I can go all out and make it look good.

Bravo! Very clean build! Thinking about a condensing lens too? Fairly cheap upgrade on the brightness for the 150'er.

I had the condenser that came with Johnzos light box he used to sell but it didn't work. I would like to try one for the increase in brightness but I have no idea what kind I need. How much of an increase in brightness can you achieve with a precondenser?

Very nice, clean build!

I need to get cracking on my projector - I get very jealous when looking at these 'near-completed' projects.

Nice...I agree with SIM, very clean

I've got a couple questions for you.

1) Could you show some close-up pictures of the wiring you did for the power input to the MST board. It doesn't look like you simply plugged the cord into the power input.

2) What did you end up doing to the IR remote wire? Is it just left hanging out of the side of the box?

For the IR remote wire I just left it hanging inside the box and the signals go through the front air intake slots. Here is how I wired the controller, it's simple:

That looks easy enough - Thank you!
