But what to do even if your smartphone doesn’t have a built-in projector option? Can you still make it to project an image on the screen or not?
Of course, yes, you can do that and for doing so, you’d have to have the following things because we are going to make our own projector that is pretty easy, efficient for outdoor watching and requires you to spend no money.
Therefore, let’s have a look at the required things to have a do-it-yourself projector by following a couple of methods for making it.
- Magnifying glass
- Precision Knife or Scissors
- Ruler, Pencil
- One double side tape, glue, and brush
- Black matte paint or thick black paper
- A shoebox or something similar
Step 1—Using the Right box and Mirror
The first and foremost important things that you will require to make your own projector are the right box that will be used to be lined with a light source and the mirror to make a magnifying glass for an actual image projection. This will make you create a bigger picture with the light rays coming from your phone.
However, to have a brighter image on the wall, you will have to use more light. Also, make sure that you have placed your phone as far as possible from the projector to get the best results. Nevertheless, you can do so by buying a bigger case or bigger box that suits your phone.
Moreover, the mirror that you gonna get must be plain, rectangular, and of the same size as your phone for an accurate self-deflection. Check Out Also Best Laptop for Photo Storage
Step 2—For having a better quality image or movie experience, blackout the interior
The next thing you’re going to do is save the image, movie, or favorite shows from the distortion or noise by making the projector quality better. To do this, you’re gonna blackout the box interior.
Remember that pair of scissors or that precision Knife? Yes, you do, just take it and cut out one narrow side of the outer box, keep it at a safe place for using it again. Also, cut the lid of the box. But don’t forget to use the knife with care.
The thing is, if you do not do this thing, you might get image deflection, and ultimately this will turn out into a low-quality image on the wall. However, you can easily cope up with this problem.
For doing so, just coat out the interior of the box with black matte paper. The process for doing this is pretty easy as all you need to do is to glue the black matte paper to the interior walls of the box.
Also, you can use black paint for painting these walls inside the box. You can paint with the help of a paintbrush and then you’re gonna let that paint dry for a while.
Step 3—Now, it’s time to install the lens into your DIY Mobile Projector
Since you have done away with the black exterior, now it’s time to install the lens into the projector. For doing this, simply remove the handle of your magnifying glass if it has it and trace its outline on the center of the paper with a narrow side that was cut out.
Use the precision knife and cut out the outline as this will allow you to easily fit the magnifying glass into that opening.

Step 4—Designing a manual and adjustable focus for your smartphone projector
This is defined as having and creating an adjustable focus that can be accounted for the distance between the camera and the phone. Or you can say, it means to have a lens that can be moved concerning the phone.
For having better concentration and conciseness, you’d have to make an additional box that is complementary to the first one and that must fit into the outer box. Once you have made this box, it’s time to make four sheets of black paper folds and fit them at the edges of the box.
In this case, don’t forget to use the ruler for precise measurement. After doing this, try to make some swallow cuts at one edge and fold the flaps. This will make the structure more solid, durable, and rigid.
Use glue to fit the lens on the flaps of the inner box.
Step 5—Installing the Mirror into the real Cardboard Phone Projector
At this far, you have a projector that projects an image that can be positioned from left to right and it flips towards the upside and the downside.
But fixing the upside and downside is also pretty easy. Because all you will have to do is to turn off the Auto Rotation feature of your phone and after that, you’d have to place your phone upside down.
However, for the correct left to right image positioning, you will need a mirror. To do this, place that mirror at a 45-degree angle against that edge which is on the opposite side of the lens.
Step 6—Creating a Final Window for your smartphone
By using the measurement of your phone’s screen, you need to draw a rectangle on your projector’s lid above the mirror. Now remove that rectangle with a precision knife. In the final process, fit the magnifying glass into the opening that you have seen in step 3.
With this, you will have a brand-new phone projector that will work like a beast and you will be able to watch a movie by using your phone and projecting it on the wall even without having a real projector.
Moreover, you can also add a fine finishing to your phone projector by painting it with shiny paint or some kind of spray.
