How to build a LCD projector with two 50 watt halogen lights.

First let me say something about this Projector project!

Yes I have had this Projector Instructable twice here now. And It`s been about two years since the first one was here with only one halogen light. Later on that year decided to put down this instructable. But at home I still tinkered around with the same projector bought a couple new things for it went though some more lights bought some more lenses and the projector was getting better and
better. So Then I had a projector with two halogen lights. With a inexpensive Wicko Camera zoom lens that I bought from E-bay. I was quite
happy with the results so I decided to put it on instructables again. But so even again I started tinkering with my projector and thought what about one light with that zoom lens? I tried it, Wow to my surprise and 50 watt halogen on a Wicko zoom lens is pretty good! (Thats the projector you see above) I think I could almost say that one halogen works just fine and is just as good as two halogen!
So for all you Do it your selfers out there Never Stop Tinkering - You never know what you might find out!

Anyway back to the projector. If you want to build this projector with one halogen just follow what I did minus the one extra halogen and put a magnifying glass lens between the light and the lens in front. see picture above.

Here are the parts needed to build this projector.

2 50 watt halogen lights, they are called mr16.

2.5 inch tft lcd screen (bought from E-bay) A car reverse monitor from Hong Kong

A book shelf speaker box (You can imagine how big that is)

Some card board

An assortment of screws

Some bendable wire (Maybe a coat hanger, I used antenna wire)

2 Elastics 

Tape

2 mr16 ceramic plugs (bought from E-bay for around 2 dollars)

Large size 12v computer fan

12 volt 250 ma ac adapter

12 volt  100 watt transformer to power the two mr16 lights

Large size lens (I got mine from a magnifying glass about 2 inches diameter, placed inside the box)

A 100 - 150 mm wicko zoom lens for a camera (works great)

Step 1 Put together the LCD

This picture here shows the LCD taped together with some cardboard to hold the LCD in place in front of the speaker box.

what i use if i don't have zoom lance. i have only magnifier glass. one lcd screen and 90 leds for light. plz reply me. i need more light . led is not good. but i dont know about halogen lamp

If you use a mr16 halogen 12v 50 watt, it is only good to watch if you have the lights off completely and your in complete darkness then you can see the picture good. If you have any light in the room coming in it is not good.

If you only use magnifier glass, it will work. 90 leds is a lot of leds I don`t know how well that would work. I use one 50 watt mr16 halogen lamp in my current projector it works good but not the best.

If anyone is interested in my current projecter take a look at my youtube video I made http://www.youtube.com/watch?v=pTKTWe07MRA

wow awesome could you give me a idea of the resolution is there a way to make a bigger screen

[mcastles]

I think the resolution is 480 by 240. I have thought of ways to add a 3.5 tft inch but I am not sure if it would work, it might. Just make the hole in the front part of the box 3.5 inch make the mount that holds the zoom lens wider higher and lengthyer. You can get 3.5 inch tft at 640 by 480 from Ebay - Search : "3.5 inch tft"

Hi. I was impressed by your DIY LCD projector. I've been working on a similar project and your instructable was very helpful. One thing I didn't see and really need your help on is how to wire the LCD? Do you have any instructables showing that? Appreciate any help or links you (or anyone reading) this could give me. Thanks. cyberdenizen

Great this is just like newtonn2's ( I think that is how you spell his username) projectors

[mcastles]

Yep. : ) This projector is came to be because of newtonn2`s first black projector. As soon as I found out I could use a small LCD display I went ahead and started to try and build one using halogen as light source.
