Creating a lens holder may require some trial and error, so don’t be discouraged if it takes a few attempts to get it right. With patience and practice, you’ll be able to create a sturdy and reliable lens holder for your phone projector.

Step 4: Inserting the Lens

Once you have completed the construction of the projection box, it’s time to move on to the next crucial step – inserting the lens. The lens is the component that will magnify the image and project it onto a surface, creating the projector effect for your phone.

The first thing you need to do is ensure that the lens is clean and free from any dust or smudges. Use a soft microfiber cloth to gently wipe away any dirt, fingerprints, or debris from the lens surface. This will ensure optimal clarity and image quality.

Next, locate the lens holder that you created in Step 2. This is where the lens will be securely placed to stay in position during operation. Carefully place the lens into the holder, making sure it fits snugly without any wobbling or misalignment.

If needed, you can use a small amount of adhesive or tape to keep the lens in place within the holder. Be cautious not to apply too much adhesive, as it could affect the image quality or make it difficult to adjust the focus later on.

Once the lens is securely in place, you can align it with the opening in the projection box. Gently insert the lens holder into the designated slot, ensuring that it is centered and aligned properly. Take your time to find the correct position for optimal image projection.

It may be necessary to adjust the focus of the lens to achieve a clear and sharp image. Most lenses have a focus adjustment ring that can be rotated to sharpen or blur the image. Experiment with different settings until you achieve the desired focus and clarity.

After inserting the lens and adjusting the focus, you are one step closer to completing your homemade phone projector. Now, move on to the final step – connecting your phone to the projector and enjoying your favorite videos, movies, or presentations on a larger screen!
