How To Use Your Phone As A Projector? | Simple Guide!

At some point in their lives, most people have wished to share a photo, a movie, a website, or a business proposal directly from their mobile.

Pricey add-ons transform a smartphone into a projector, allowing users to project whatever they want onto a wall. Still, No one would have to pay for such a tool when they can make their own for free. This article will tell you how to use your phone as a projector in easy steps.

9 Steps – How To Use Your Phone As A Projector

You can’t actually turn your phone into a projector. However, the following items can be used to turn your phone into a projector:

• Black Rectangular Shoe Box
• Magnifying Lens
• Black Paper
• Paper Cutter 
• Foam Board
• Mobile Phone 
• Sticky Tape
• Glue 
• Pencil

Step 1: Make a rough sketch of the lens diameter.

On one side of the box, place the magnifying lens. To get great results, make sure it’s in the middle. Now grab the pencil and sketch the lens’ diameter. It is a simple procedure, but you must not rush through it. Remember that tracing the shoebox is a little more difficult than tracing on paper.

Make sure you draw dark lines to trace the diameter. After that, you can continue to the next stage.

Step 2: Cut the boundry

Cut the traced boundaries with the paper cutter now. A paper cutter is recommended since it allows for greater precision. Place the box on a table and trim the diameter using a paper cutter with soft hands. Make sure the surface beneath the box is not damaged. To ensure that the lens fits precisely, carefully cut the diameter.

You can cut the boundary a few millimeters longer than the trace while cutting. After that, gradually trim the edges to achieve the desired size. The lens will not fit properly if the box is not trimmed to the correct size.

Step 3: Place a cover on the box.

This step, which explains how to use your phone as a projector, is crucial. Those who don’t get the outcomes they want usually make mistakes in this phase. You should Take the black paper and cover the box at this point. Make sure you use just black paper because other colors will not properly reflect the light.

Consider it as if you were creating a dark chamber. In such a setting, a projector will produce a bright image. However, when used in a less dark room, the same projector will not produce the same results. We hope you understood what we were trying to say.

Step 4: Secure the lens

It’s time to connect the magnifying lens to the box when you’ve finished covering it. You trimmed the box to make room for the lens. Attach the lens to the piece of box that you cut out. The lens must be adhered to using glue in this case. It would help if you also used sticky tape to improve your grip.

After attaching the lens, ensure it’s totally dry before moving the box. You must be patient since one false move will undo all of your hard work.

Step 5: Construct a phone stand

We’re almost done teaching you how to utilize your phone as a projector. We’ve made the projector’s casing up to step 4. Now you must cut the box in order to create a mobile phone stand. It’s also a crucial step because there’s no other way to get the phone into the box.

You’ll need a foam board that’s somewhat larger than the size of your phone for this. First, cut two foam board pieces that are exactly the same. Then, for further support, place one of them vertically and the other horizontally. To create a mobile phone stand, use the glue to adhere the foam boards together.

Step 6: Put the phone in its rightful place

You must now attach your phone to the previous step’s mobile phone stand you created. First, to avoid the screen rotating accidentally, take your phone and turn off the auto-rotation option. Next, take the sticky tape and glue and use it to secure your phone to the phone stand.

Because the glue or adhesive tape will damage the casing (body) of your valuable mobile phone, make sure you use the protective cover.

Step 7: Set up a mirror

Because a magnifying lens (convex lens) provides a big but reversed image, this is yet another critical step. As a result, if you don’t put a mirror between your phone and the lens, the image will be inverted. To get an expanded and straight image, position a mirror between your phone and the mirror.

Step 8: Put the box away

After placing everything, shut the box and form it into a DIY projector. Simply ensure that everything is in its proper location and that the glue and adhesive tape are used appropriately.

Step 9: Make a screen projection.

Now that your home projector is set up, it’s time to put it to the test. If you have a projector screen and wall, you can test projecting on it to see if your method is successful. If you don’t have access to a projector screen, you can project your smartphone’s screen onto a wall. Also, determine the ideal distance for obtaining a clear image quality.

So there you have it: 9 simple steps to using your phone as a projector. Of course, you can’t expect optimum output quality from this projector because projectors have many functions that this homemade projector lacks.
