How To Make A Hologram Projector

Picture a 3D image floating in the space and visible without wearing 3D glasses. That’s precisely what a DIY hologram projector will give you.

While this may sound like some complicated or alien tech best left for the nerds, you’ll be surprised that it’s easy to build your own hologram projector at home and project those holographic images straight from your home smartphone.

The following guide takes you through the key steps to follow to make a 100% working hologram projector. We’ll also answer any additional questions you may have about holographic projections.

What materials do you need to make a hologram?

Special materials are needed to make a hologram. If you’re simply making holograms at home for fun, you can do so by exposing the hologram image/video on an extremely high-resolution photographic film coated with a silver halide emulsion.

A perfect example of such material is the base of a CD or a piece of transparent acrylic sheet. When the silver halides residing on the base are exposed to light, they absorb light. Electrons within the layer then attach to halide crystals—creating sensitivity specks. And that’s how you view a holographic display of a 3D image at home.

What materials do you need to make a hologram

However, holograms for mass production are made by exposing them to a glass plate that has been pre-treated with iron oxide and then finished with a photoresist coating.

How to make a holographic projector?

Since this is a DIY process and we’re not making a large hologram projector, we’ll be using the first type of materials discussed above.

You can easily access this material from an old CD lying at your home. The CD will help you create a smartphone hologram with mirrors since you’ll be turning it into a pyarmid whose sides act as mirrors angled at 45 degrees to create the hologram image.

How to make a holographic projector

This guide will involve making a simple holography pyramid for projecting 3D holograms from your smartphone.

Things you’ll need:

  • 0.5mm transparent acrylic sheet
  • Scissors
  • Cutting blade
  • Clear tape
  • Ruler
  • Pen
  • Smartphone

Steps to follow:

In the following steps, we’ll come up with a 3D holographic projector (or a hologram pyramid), converting the plastic sheet into the shape of a pyramid.

When a hologram image or video is shone on this pyramid, its 4 symmetrically opposite variations will be projected onto the 4 sides of the pyramid.

Each side will then project the image falling on it to the center of your DIY projector.

The 4 projections will then work together to form a 3D illusion that appears as if it’s midair.

Step 1. Prepare the pyramid template

You first need to get the template for your projector. There are two ways to go about this. You can either print the template on a piece of paper.

Or you can trace it on graph paper.

Regardless of which method you go with, you’ll end up with a precise piece of the following image.

Step 2. Trace the pyramid on the acrylic sheet

Trace out the shape of the pyramid above on a plastic sheet with the help of a ruler and pen. Next, use a cutting blade and a ruler to carefully cut out the outline.

Be sure to make your cuts as precise as possible to ensure you end up with a perfect pyramid.

If you printed the cutout, lightly score the red edges using the cutting blade. This will make it easy to fold the edges better and make a pyramid shape. Now use a clear cello tape to stick the open edges of the plastic sheet together.

If you used a trapezoid template instead, simply join its 4 edges to form a pyramid shape and then stick them together.

Step 3. Time to project holograms!

Having pieced the plastic sheet into a pyramid shape, you now have a complete projector ready to output holograms.

Play a hologram video on your phone (YouTube has plenty of them!). Place the pyramid in the middle of the phone screen, sit back, and watch the 3D illusions floating in the air.

TIP: Make sure you turn off the lights before you start projecting the hologram for the best watching experience.

How much does a 3d hologram projector cost?

Like other projectors, the 3d hologram projector price varies from model to model. These projectors come from different manufacturers and vary in terms of size and features.

A simple prims projector for use with smartphone (like the one we’ve just created above) is the cheapest. It will cost you around $30 to $50. Bigger models, however, cost you anything from $200 to high-end models costing up to $1000 or more.

How much does a 3d hologram projector cost

How much you should spend on a projector will depend on factors such as the brand, the projector size, resolution, and the features it comes with.

How do you make a hologram screen?

To make a hologram screen, start by drawing an image on a piece of paper or screen. We advise you to start with a black or dark-colored image to enable the projection to look more clear and brighter.

Before drawing the image, make sure you draw “X” to help divide the screen/paper. Now draw a picture on one of the 4 triangular spaces created by the letter. Repeat the process for the other remaining spaces.

You should end up with 4 diagrams. When you place your projectors in the middle of the X, you should be able to obtain a 3D projection of your image.

Can an iPhone do holograms?

Yes, you can turn your iPhone into a hologram projector machine. However, it can’t do this on its own, so you’ll need to get an iPhone holographic pyramid to enable you to view 3D illusions from your iPhone. The pyramid is pretty inexpensive, and a decent one will cost you around $20 to $50 bucks.

Once you have the pyramid, go to YouTube and look for content specially made for hologram technology. YouTube has loads of such videos, so finding one shouldn’t be a problem. Now load the video onto your phone and place it on a level surface. Gently position your pyramid hologram viewer as outlined in the instructions and hit the play button. You should now be able to see magic unraveling in front of you!

Alternatively, you can come up with your own phone hologram template. We discussed the step by step by guide on how to do this. You just need to use the base of a CD and turn it into a CD, and then use it to project 3D videos from your phone.

Can holograms be seen in daylight?

Absolutely! The white-light hologram, one of the most common types of holograms, doesn’t require a laser to reconstruct images. This allows you to view it in normal daylight. You’ll find these holograms being used on credit cards as a security feature.

What is 7D hologram technology?

7D hologram technology is an advancement in the hologram field that enables you to capture holograms in up to 7 parameters which is a big lead from the popular 3-dimensions projections.

But how is that possible? As you already know, our universe exists in 3-dimension space, and time is often considered the 4th dimension.

A 7D hologram has many dimensions because it is captured from a high number of positions surrounding the subject or scene of the hologram.

Each position is then described in 3D space.

Each of the capturing positions gives a variety of directions in 2D space.

Two additional parameters are then captured for each direction: time and image intensity.

All of this adds up to 7 parameters, which give rise to 7D holograms.

Note that the smartphone projections we discussed earlier are 3D. You cant use that method to create a 7d hologram projector with your phone.

Final Words

Making a holographic projection device for your phone at home isn’t rocket science. As you have in this guide, you can achieve this using an acrylic/plastic sheet or the base of a CD from your old CD case lying in your home.

The process is pretty simple and takes approx. 30 minutes. When done correctly, you should end with a highly functional projector that displays the 3D hologram images from your smartphone.

Remember, you can also get a store projector for your smartphone. These devices are quite inexpensive and will give you hours of phone projecting holograms on your smartphone.
