Note: If you don’t have black matte paper, you can use black paint. It’s imperative that you paint all of the adjacent walls exactly and don’t miss anything.

Step#4 Adjust the Lens:

The lens can be placed in the cardboard box once you’ve gathered all the necessary supplies.

Make sure that the lens is centered on the side of the camera. Mark the precise location of the lens on the box with a pencil after it has been appropriately positioned.

Step#5 Install the Lens:

Install the huge magnifying lens in the cardboard box after marking the ideal location for it.

Use a knife to carve out the lens’s outline carefully to accomplish this. When working with thicker pieces, your best bet is cardboard cutters and sharper blades.

Place the magnifying lens where you cut it and tape the glass to the location to keep it in place. You must ensure that the lens is positioned appropriately and that the inner of the lens, where you can see clearly, is within the box.

Step#6 Place Laptop in the Box:

You only need to insert the laptop into the projector for this stage. Turn the laptop on its side to make it fit in the cardboard box. Your homemade laptop projector is nearly ready after the laptop is placed in the correct location.

Now that you’ve tested your projector, you can proceed. Do some testing by watching a movie. You can improve the picture quality by moving the laptop around a bit. Until you get the result you want, play around with the sliders.

Because the laptop will be in a container, you may require an extra speaker to produce a strong sound. As a result, the sound will be imprisoned within. Use a VGA cable to connect the devices if your speaker has one.
