PROJECTOR FOR UNDER $100 (It could be free if you have the components)

I just saw one of these fully operational, it was a great experience. Definitely creativity has no limits.

I asked for the source and here you have, an amazing projector.

You need a LCD Flat Screen that's not in use, if you don't have one you can find it easily in craigslist.org for $50 or less. Ebay is a good place to get a used one too. You will also need an Overhead Projector, again I just saw one in craigslist for $45.

Watch the video, it's really simple to build.

Now, after watching the video you might have some questions...

How do you get the  show on?.How do you power the screen?
When you take apart the monitor, you're only removing the external case and the display screen that captures the picture.When you place the guts on the overhead projector you still have all your component inputs and cords attached to the display. You just plug everything back in as you normally would.

Do I really need the fan?
The projector operates by using light from a bulb (bottom portion of projector) projected through an object and the reflection projected by a mirror (top portion) on to a surface. The light produced is hot enough to damage the LCD. Combine that with the heat the LCD is putting out means definite toast. An external cooling device is needed to prevent overheating.
