Ace_3000....pictures of Projector?

[richardgerson]

hi guys love the work you people have done.

im starting a project myself and need a bit of help. im going for the cheap route but dont mind putting in alot of work. im going for a screen size of 50" - 55" but dont mind a bit smaller if the quality will be better. do i need a frensel if the lens covers the whole lcd, or is it best to still use one.

has anyone got a basic diagram of the setup for a 2.5" lcd projector.

would it be possible to use this light as a light source. and a fresnel lens witha 300mm focal length to drict the light into my lcd or is that not nessercary.

Tungsten Halogen Flood 150 watt

thanks

Hi Ace,

and thanks for a grate project you are working on

All i wanted to ask is your spec´s i mean what LCD are you using (or recommending) and Fl ect.

hey ace how do you get that bulb in a ellipsical reflector???

Through a 22mm hole buddy, you just poke it through.

You cant do this on the larger bulbs. I have taken a shot of my new light unit against the exact 175w mh bulb you have.

That 175w light is brand new btw, if anyone wants it let me know by email. Its been sitting here for over a year doing nothing, never fired up and comes with ballast socket, ignightor and cap, all brand new.

Here is another shot of the new light unit. The overal size is 104x101x101mm, (length x width x hight is shorter then a computer mouse).

The reflector is held in by a spring i made out of piano wire as you can see in the next 2 shots.

The unit isnt finnished as there are 2 panels that go on the top and bottom that mount flush to the lip on the sides. Overal this thing in real life looks very pro, but on the cam nothing like it. Ill finnish the other 2 panels off asoon as ive finnished the design for this in the projector, so i can sort out the cooling.

Before any of you guys chuck a fit and say the lamp isnt central lol it is, its just from the veiw from the cam from which i took the shot.

Second pic showing spring mounting.

And here is a side shot showing the side of the spring.

Mind the odd bolt on the lamp being too long as stated the unit is not done.

The performance of this new elipsidal isnt bad, its the same brightness (if not brighter) as a 250w HQI-TSD with the arc being condensed, so that means its going to be alot brighter then a standard 250w setup.

For those of you who have played with a parabolic reflector and thought the Parabolics wer touchy, these reflectors are 10x worse. Everything has to be spot on or it wont work right.

Ill be back with more updates at a later date.

Heya buddy read back abit in the thread , all of the answers are there. Im using the lilliput 7inch which has a native of 800x480 and compresses upto xga. if you want to know what a good focal is on the rear frensel, go 210 -230mm and for a top either go 210mm and up to 320mm and you wont have a problem.

Indeed it is looking good .. very "Trevlike" indeed mate hehe...but its really what we have come to expect from you Trev, your work has that pro finish no doubt. Don't know about others on the forum but I for one attempt to replicate the finish you achieve ... all to easily it seems :-p I guess you have been doing it for years though and it certainly shows with the research, finished product and the overall results you achieve. Your both knowledgeable and gifted with your hands Trev and certainly an asset to the forum mate...keep up the good work Trev, shall be watching with a keen eye and a fingers poised over the ctrl+c keys hehe...

p.s we can all be thankful that the reflector only reflects light well and not Trevs image ...hahaha soz mate couldn't resist that jibe :-p
