DIY - Hologram Pyramid and Pepper's Ghost

Do you believe in magic? Let me show you an optical illusion that will blow your mind and will cost absolutely nothing out of your pocket in making one of your own. Fairy tales have always talked about having a little man in your hand that can walk, talk and interact with you. It's now time to make the fairy tales a reality. Give your imagination a wing and fly with me. Ever wanted to watch videos in 3D without using 3D glasses? This short tutorial will teach you how to make a very simple device to watch hologram videos on your smartphone or tablet. Just by spending 10 minutes of your day and by using simple household stationery and some scrap material, you can watch hologram projections from your phone and be amazed. Pepper's ghost is an effect where you project something with a dark black background out to a transparent screen at an angle and it reflects off at an angle. So when someone looks at the transparent screen, they see the reflected image or the ghost. The background of the pepper's ghost has to be black since you only want the ghost to be projected on the screen. For this project we need a plastic sheet from a packaging material or cd case, tape or super glue, permanent marker or pen, ruler, scissor, knife or a glass cutter, a smartphone or a tablet and optional sandpaper and cardboard. I came across four different ways of making this hologram. Using a pyramid structure, putting the screen at 45 degree angle, using a cling wrap and projecting the object using a projector or simply by reflecting light falling on an object on a transparent sheet. In this video, I'm going to show first two methods of generating the pepper's ghost. Let's start the project by drawing a basic rhombus shape on a piece of paper. You can also print the shape using a printer. The bottom need to be 6 centimeter, the height need to be 3.5 centimeter and the top 1 centimeter. Once you have the template ready, place the plastic sheet or the cd cover on it and very carefully cut the four sides out of it. Now using a clear tape, join the sides. Make sure to leave a bit of gap between the sides as that will help you in folding the sides. You can also super glue the sides but frankly speaking, I did not have much of luck gluing the sides as the sides keeps falling apart. Hologram pyramids are pretty cool. You just place the pyramid on top of your tablet or the smartphone screen while playing a hologram video and a 3d object floats and moves inside the pyramid. The device creates a 3d like illusion for viewers and make an image or video appear as if it's in the media. The pyramid reflector creates an image even if you look at it from different sides. It's very important to have your phone's brightness up high to see a clear image. Let's start again by making the transparent screen. The screen should sit at a 45 degree angle on the phone. For that you need to build two sides and a flap that will stick to the phone. The height of the screen should be same as that of the base of the screen. We can use google to calculate the length of the third side using Pythagorean theorem. Now on a piece of paper, draw a line equal to the length of the screen. Then draw two lines on each end at 90 degrees with the length we calculated for the height of the screen. Close the top and then for the sides, find the middle and draw a perpendicular line from there. Now using a ruler, draw a line from one edge of the perpendicular line equal to the width of the phone's screen. Same for the other corner and then repeat it for the other side. Finally add some flaps to the edges. Now place the transparent screen on the piece of paper and trace the template out using a marker. As much possible draw the marked lines on the outer side. Cut it out from the inside of the marks to avoid the lines from the marker and then fold along the edges as per the template. Tape this to your smartphone and you're all done. Now by projecting the ghost from your smartphone you can amaze many people. Thanks again for watching this video. I hope it helps you.
