Step 1: Assembling the cardboard template

The first step is to cut out some  cardboard from your black binder and use it to construct a small box that will house your monitor.
You also have to glue each lens to their rings (with the curved part facing up), and then proceed to gluing them together, with one on top of the other. Please note that the cardboard box is not the actual housing and will only be used to mark the size and shape of your flexible housing. Next proceed to gluing the lens into a hole that you must cut out from the box. Make sure the hole is centered or your imaged will not be perfect.

Step 2: Taking apart the Monitor

Take apart your 3.5 inch TFT LCD Monitor with your screwdriver and remove the actual display. Be careful though as it is very fragile.
Next cut the monitors video and power wires and then splice them together to shorten the cable's length.

Step 3: Splicing together a power cable

In this step you will take your 9vDC plug,and splice it together to your Heavy duty 9v battery clip. Splice them together so that you have a very small cable. Remember, you are trying to make this as portable as possible!

Step 4: Adjusting the focus

For the this step you will simply power on the monitor and place it in the box to determine how far away it should be from the lens in order to achieve good focus. Don't forget that the lens will mirror the image, so you will be installing the monitor upside down.

It is somewhat blurry, and it projects onto the wall an image that's about 1 foot by 1 foot. This instructable shows you the overall concept, but you should experiment with different lenses from different things, like a binocular, a magnifying glass, or if you can, use a lens from a real projector.

The projector utilizes the flexible material to be able to fold down just enough to fit into a pocket!
