This is because the 17 " screen is bigger than the overhead display area and is also rotated 90 degrees to lie/fit properly on the overhead. The overhead is connected via my laptops VGA and is displayed as my second monitor with XP extended onto it. I then used a black background wallpaper so the video blends nicely onto the screen. The clear box you see next to the overhead is the LCD power supply and video connections. I mounted it vertically (in the box) so the cable fits right next to the LCD. Check out the links for a more detailed how to. Total Price:$120....hours spent ~ 24 hours construction time, and a somewhat adept computer skill level.

hi, i think it might be easy, but i want to know the steps on how to get power for the pc fans. LCD, take them apart, put it on top of the overhead projector, that's it? if it's that simple, then i just need help on the fan, thanks!

Yes, it was simple. For the fan, PC fans typically run on 12 Volts DC. Just obtain a power supply and a 12 Volt PC fan for cheap. The only other issue is housing the electronics that are now exposed once you tear the monitor apart.

Hi mate, excellent work Can you tell me this. The picture with regards to colour saturation/ bleeding e.t.c How well does the overhead projector portray the image, and would this mean whatever resolution you use on the LCD monitor, can be accurately displayed via just using the overhead projector ?

Much of this depends on the size and quality of the lcd, as well as the size and brightness of the overhead projector. On this one, it isn't vary bright of a projection. Also, the resolution is messy as the screen is bigger than the viewable space on the projector. If you get the correct equipment, it does work vary well.

Did you leave the backlight of the lcd or did you take it out ?

leave it on it makes the picture much better

can you show how to make this projector step by step?..pls?....tanx!

Hi,Can I use an lcd av monitor for this.GREAT VIDEO

We used a dell monitor for this. Some monitors are much more difficult to tear apart than others. I ultimately don't know.

The fan doesn't have to be mounted; as long as the lcd screen is getting cooled enough, you should be fine. The only reason why we used computer case fans is because they are cheap, small, and make a more compact design resulting in less time to set-up the projector.
