How to make a Hologram projector at home

This article will guide you how to make your own Hologram projector at home in just 5-10 minutes. It's easy and inexpensive! You can turn your smartphone into a 3D holographic video viewer with this simple DIY projector. Unfortunately, this illusion is not a real 3D hologram, it still uses 2D images/animations/videos to create the effect, while a real hologram recreates a 3D object or thing and with the latest technology, it requires the use of a diode laser beam, glasses and precise glasses placement, which is very space-consuming and time-consuming.

Step 1: Gather all the parts and tools to create this device

You only need a few things to make this device:

1. CD case or Acrylic glass (transparent)

2. Graph paper

3. Pen, pencil, scale

4. Scissors and glass cutter

5. Tape and super glue

Step 2: Now, let's start making the projector!

The first thing you have to do is draw a diagram on a graph paper of the pyramid faces as shown in the picture. Here, the example will be a medium sized pyramid, you can reduce or increase the size according to your requirements. Now, if you want a larger size, choose the size: Base = 18 cm, Height = 10.5 cm and Top (1 cm or 2 cm) as it is. And if you want a small size, leave: Base = 6 cm, Height = 3.5 cm and Top = 1 cm

Step 3: Cut the glass

Now, cut the glass or CD cover with a knife to the chosen size on the graph paper,

Cut 4 acrylic glass shapes as shown in the picture.

Step 4: Connect the glass pieces together

Now, stick the glass pieces together with super glue, and you're done!

Now, you'll need some video and a smartphone. So let's move on to the next step to create that illusion.

Step 5: Search for videos on YouTube

Now, take your smartphone, go to YouTube and search for hologram videos. You can find a lot of 4-sided hologram videos. Place your hologram projector in the middle of your smartphone, play the video and make sure to turn off the room lights for a closer look.

Explain how the effect works

Now here is some information on how the DIY Hologram projector works: The video using this device will play the same video from 4 directions and when they are reflected in the cells of the device, it looks like a floating 3D hologram.
