When you think about projecting your mobile screen on a big display, a projector serves as the viable option. But what if you don’t have a projector? You will be surprised to know that you can project a phone screen to a wall without needing a projector. The process is not easy, but it is inexpensive and needs little effort. Today’s technology has significantly improved, and nowadays, you can do a lot of things with your smartphone.
Now, let’s check out “how to projector an image on a wall without a projector.”
First, you need to arrange certain materials which will help you in creating a DIY projector medium that will maximize the visual. You will need tape, a box, black paper, pencil, x-acto knife, magnifying lens, glue, binder clips, and obviously a smartphone. Basically, these materials will help you create the DIY projector and help you project images on the wall.
Step 1- The first thing you need to do is to prepare the box with the magnifying lens as it will lay down the base for creating a DIY projector for your smartphone. To prepare the box, you need to put it on the table from the small side and carefully put the magnifying glass on the other end.
Once you have placed it, now use the pencil to trace it properly. You can utilize any kind of support system while tracing with a pencil because it will help you maintain proper accuracy. It is advisable to use a sturdy paper box because magnifying lenses are generally heavy, and it needs a sturdy base. You should avoid using fragile paper boxes as they won’t be able to hold the whole setup and can lead to misalignment.
Step 2- After you have carefully placed the magnifying lens, it is time to position it correctly. You will have to utilize the knife and cut the portion of the box with tracing of the magnifying lens. You should use a soft hand while cutting the portion from the box and make sure there is no uneven cutting.
Once you have cut out the portion from the box, it is time to position the screen properly in that cut-out area. After placing the lens in the exact position, you should use tape to create a firm setup. You should adequately tape its position so that even if you lift the box, it stays in the cut-out area. One thing to remember, the inside of the glass should face the inner of the box because it will help in magnifying the incoming visuals.
Step 3- Here comes the crucial part where you will have to cover the entire interior section of the box with black paper. There are numerous ways to attach the black paper to the interior, and you can do it the way you feel best. You should use quality glue and apply it correctly on the interior part so that the black paper can stay attached. While attaching the black paper, you should take care of the fact that there is no flaky portion on the interior as it could block the view.
Moreover, you should not leave any gap in the interior, and every inch of the box should be covered with black paper. Avoid using ordinary black paper from local stores. It would be best if you can manage to use black film from an online store that has a pitch-black covering because it will solve a part of the query of “how to project an image.”
Step 4- To complete the setup, you need to place the smartphone in proper alignment for proper magnification. Place the smartphone in such a way that it doesn’t ruin the black paper in the interior. Use both the small and big binders to attach the smartphone in its position and adjust it in such a way that it doesn’t fall.
Once you have placed the smartphone, you should check whether it is appropriately aligned with the interior of the inside of the magnifying lens. After this, your DIY projector is ready to project on the wall, and you can place it anywhere you want. You can attach a hard paper or something similar underneath the box so that it has a strong base for placement.
Step 5- In this final step, your only job is to set up the smartphone so that you can seamlessly project content on the big screen. If you are using an Android smartphone, then you just have to rotate the screen so that you get a landscape view on the white wall. The rotating option is available in the drag-down feature, or you can access it from the settings.
However, if you are facing trouble rotating the screen, then you can download a third-party app that will assist you in solving the problem. However, if you plan to project from iPhone to the wall, then you need to go to accessibility settings and from there access assistive touch. From there, you have to head to the “device” option, where you will get the rotate screen facility. Nowadays, modern iPhones may have the rotate screen option as a shortcut, so you should check that fact.
Once you have rotated the screen, now it is time to position the smartphone so that it finds the right focus. You should slowly move the position of the screen until you find the correct position from where the images are properly shown on the white wall. Basically, you have to opt for a trial and error process until you get a clear image on the big screen. Now you are ready to enjoy all your favorite movies and that too without spending a chunk of money on a projector or screen.
However, you might feel deprived of audio experience, so it would be best to utilize a Bluetooth speaker for room-filling audio. You can also use a wired speaker, but then you will have to make a separate hole in the box for connecting it.
