well I had an itch that needed to be scratched. got bored and built the box today.

Box.

Lid Up

Black Paint

Snap crackle pop.. buzzz....

And I said.... LET THERE BE LIGHT!!!!!!!!!!!!!!

Just too neat.

First (kinda) test.

That is the "nipple" on the MH Bulb approx 4 inches diameter, at about 15 feet away, lid open, and still light outside, with the garage doors open, on painted white plywood doors and no reflector..

I'm impressed so far.

Good job Rotor, Glad to see you did not give up on it because of monitor.

Yea just about perfect projection of the bulb, just like it should be, wait will you finish it will be great.

Had to redo part of the box (measurement error) and add a few mods.

Hood up!

Focus Box

8 inches of MAX travel (in and out) 5 inches sturdy.

Fan Box. (Going to mount the fan on the outside so I can butt the ballast aganst the back wall. Will be open on the opposite side of the fan to block some of the light. This will house all the electrical switches, Power plug and Video inputs.

And a little peek through the triplet.

That's looking superb Roto. I love your focus box design.

Still have to carve the bowl but, looks purdy inside.

Held the fresnels by the end measured to spec. put a plate of glass that I scribbled on because I was getting exited

Either that or I have a REALLY big sharpie.

The room almost setup. Guestimated 120" Horizontal picture. red box is to give an idea of what widescreen video could be.

Nice job.

About the focus box---- I started with a similar focus idea where the whole front wall moves but it interfered with the pc boards that extended into that front floor area from the LCD. For that reason I changed to a smaller box in a box to clear everything when I wanted to move the projector back for a big picture and had to "rack in" the focus all the way.

What kind of LCD will you be using? Do you know where the PC boards are going to have to sit?

I thought about that last night. I'll remove the bottom of the box and probably put rails in it. I really doubt I will need to go 4 inches in.

Monitor is a "557 V2"

Here is a pic of my Pj with the Benq boards and my focus box about all the way back. My focus box is 4" long.

So RotorDemon whats new

Workin workin.. setting up the room.. I changed it *agian*

Waiting for the LCD to get here. :angry:

Switch and fan box.

Switch and fan box. open.

Neat little pic... Try holding a camera while doing an exposure shot LOL

The wire going into the box is a temp probe I haX0r3D together. No lenses in there yet and it was staying about 86-94 degrees depending on how far I had the fan box open.

And all the action on the wall was........

thats one big azz MH Bulb and Reflector........ but looks good projected.

Check out the projection on Page1 in the garage with daylight...hell you could almost watch movies there if the garage door was shut halfway.
Nice job Rotor...hope you have caught/found the group that hacked your website...although it appears that they didn't have anything else to do so they deleted some files from your server and left :angry:

If the reflector were working as expected, shouldn't it be lighter than it is? In that image there is just a halo and it is otherwise dark. To my unknowing eye the reflector doesn't appear to be reflecting much.

Trust me.. even the image of the bulb on the wall is bright..

Sunglasses ON!

Don't forget the reflector we use we are trying to return the light back to the arc of the bulb not project it forward, thats what is happening and why you do not see a bright light from it and see just the bulb, because the fresnel is what gathers the light and it is concentrated to the center of the arc of the bulb....

woo hoo.. Pics.

more..

one more..

133" Wide

RotorDemon,
looks fantastic man, great job.
watch out the stingrays going to eat you. he has his eye on you...

Rotor,
Did you take the pictures while the movie was playing? It just looks like they are a little fuzzy in the background....then again it is probably just the aftermath of pausing the movie while the characters are moving.

Looks great though regardless. That screen size is huge I'm assuming you have kids, hense the Little Nemo. Have she/he/they seen this thing yet? I was worried that it would terrify my two-year old son to the point that he would never watch it again

great job!! man that is a huge screen.....

i think its just his camera because he looks fuzzy in the pic as well.

rotor nice big picture with even lighting... i like it.

Good job, it look s very efficient design.

I have few question:


I was wondering why your fan doesnt have an air flow from outside. I means,it is enclosed in your little box right?

What kind of reflective metal did you used for the bulb compartiment? aluminum?


thanks


CBR_MAN

im sure after the put the lcd inside the projector he provided the air intake per the guide, and that is alumn, used in light area.

Massive

I hope you are not 3 feet tall, as I want my image to be as big as yours if you are about 6 feet tall. . . that is what I am interested in, the 10 foot -tall- images [and 15 wide], not the 10 foot wide [and 6 tall].

that projection looks really nice and inspiring

// sorry if I seem to be a giddy little child, I am just anxious to build

The movie was paused, but the camera wasnt the best in the world. and yes.. I have a little girl

Image shown was about 6 foot tall by 11 feet wide.

fancy. . . it looks so much bigger

I still have big expectations


must have been the big stingray trying to eat you that makes it look so big

Rotor looks nice, i guess u hade to move to living room for that size screen... lol
