How to Make a 3D Hologram Projector Using Your Phone

Creating a 3D hologram using your phone is not science fiction anymore – it’s a DIY project you can finish in under 30 minutes with basic tools and materials. This guide explores a simple, budget-friendly way to turn your smartphone into a real holographic viewer using reflection and perspective. This method works by reflecting 2D animations in a transparent pyramid to create a stunning floating 3D effect.

What Is a 3D Phone Hologram

How to Make a 3D Hologram Projector Using Your Phone – DIY Guide

A phone-based 3D hologram is an optical illusion created by projecting video onto angled transparent surfaces. The image appears to float in the center, visible from multiple sides. This is not a true hologram (like laser-based systems), but a simulated one using light and geometry.

Still, the results are visually impressive and require no expensive technology.

Materials You Need

A transparent plastic sheet (like an old CD case or clear packaging)
Graph paper or printed template
A sharp cutting tool (box cutter or precision knife)
Ruler
Clear tape or strong glue
Smartphone or tablet
Hologram-ready videos (available on YouTube or apps)

Step-by-Step Instructions

1 – Prepare the Template

Draw or print a trapezoid with the following dimensions:

Base: 6 cm
Top: 1 cm
Height: 3.5 cm

Once the video starts playing, you’ll see a 3D object appear to float inside the pyramid. Try rotating your view – the object stays centered from each angle.
This shape will be used to cut four identical pieces from the plastic. You can scale it down for smaller phones or scale up for tablets.

2 – Cut the Plastic

Place the template on the transparent plastic. Carefully trace and cut out four trapezoids. Be cautious while using the knife – precise cuts result in better image clarity. Smooth edges with sandpaper if needed.

3 – Assemble the Pyramid

Use clear tape or glue to join the four trapezoids by their edges, forming a small inverted pyramid without a base. Make sure it’s symmetrical and sealed – gaps will distort the illusion.

4 – Position on Phone Screen

Turn your phone horizontally and place the pyramid upside-down (small top facing down) at the center of the screen. You can find special “hologram pyramid” videos on YouTube – search for “hologram video 4 sides.”

5 – Play the Video and Watch

How It Works

The illusion is based on Pepper’s Ghost – a technique invented in the 1800s for stage illusions. Light from the screen is reflected on the plastic surfaces toward your eyes. Each face shows a different angle of the object, creating depth and realism.

Tips for Better Results

Use a dark room for stronger effect
Clean plastic thoroughly before use
Use HD videos for sharp projection
Make sure the pyramid is centered and stable

Advanced Ideas

Create a larger version using a tablet
Build a housing to block external light
Use your own 3D animations in compatible formats
Try colored transparent films for creative effects

Educational Benefits

This project is excellent for learning:

Basic optics and light reflection
Geometry and spatial visualization
DIY design and precision crafting

It’s perfect for science fairs, classroom demos, or simply impressing friends with a futuristic display.

Final Thoughts

Making a 3D hologram projector from your phone is surprisingly easy and fun. It blends science, creativity, and hands-on skills in a rewarding project that costs almost nothing. Whether you’re a student, maker, teacher, or tech enthusiast – this DIY idea opens a small window into the world of holography, right from your pocket.
