When the word hologram is heard, it is directly related to a projection that is made by very complicated and expensive electronic equipment. However, the action of making holograms is not something so new, it is even studied as a tool of photography. Since it is very easy, learn how to make a professional homemade hologram projector.
To make a hologram requires, beyond an expensive holographic projector, the understanding and comprehension of the visual phenomenon that allows visualization. By understanding this you can make a professional homemade hologram projector and get amazing results.
However, there is also a slightly less complex option like making a 3D hologram with your Smartphone if the hypothetical scenario arises.
What is a Hologram?
In short, a hologram is a photographic phenomenon associated with the vision of images in three dimensions, a product of the use and management of light. This works thanks to the reproduction of several opposite planes that will generate the different faces of the projection in space.
Holography is precisely the study of three-dimensional effects in photography, because it is widely used to generate effects in the film industry.
Steps to make a professional homemade hologram projector.
Creating a homemade professional hologram projector can be an exciting project! Here’s a step-by-step guide to help you make one:
Materials Needed
- Transparent Sheet: A clear, transparent plastic sheet will be the main material for your hologram projector. This could be a piece of clear acrylic or a transparent CD case.
- Smartphone or Tablet: This will be used to display the hologram video.
- Graph Paper: Useful for making precise measurements.
- Pen and Ruler: For marking and measuring the dimensions on the transparent sheet.
- Cutter or Scissors: To cut the transparent sheet according to your measurements.
- Tape or Glue: To assemble the cut pieces into a pyramid shape.
Steps to Make the Projector
- Design the Template:
- Draw a trapezoid shape on the graph paper. The dimensions can be approximately: base 6 cm, top 1 cm, and sides 3.5 cm each. These dimensions can be adjusted based on the size of your phone or tablet screen.
- This trapezoid will serve as the side of the holographic projector.
- Cut the Transparent Sheet:
- Place the graph paper template under the transparent sheet.
- Use the pen to trace four identical trapezoids onto the sheet.
- Carefully cut out the trapezoids using the cutter or scissors.
- Assemble the Projector:
- Join the trapezoids’ long sides to form a pyramid with a hollow top. The smaller ends of the trapezoids should meet at the top.
- Secure the edges with tape or glue, ensuring that the structure is stable and the joints are clear and clean.
- Using the Projector:
- Find or create a hologram-specific video. These videos have four symmetrical images that when projected, create a 3D effect.
- Place the projector on your smartphone or tablet screen, with the hollow top facing up, in the middle of the video image.
- Turn off the lights for a better effect, and play the video. The hologram should appear within the pyramid.
Tips for Best Results
- Ensure the transparent sheet is as clear as possible to avoid blurring the hologram.
- The room should be dark to enhance the holographic effect.
- Experiment with different sizes of projectors to see what works best with your device.
Remember, the quality of the hologram will depend on the transparency and precision of your pyramid, as well as the quality of the holographic video used. Enjoy building your homemade hologram projector!
The first thing to do to make a professional homemade hologram projector is to download or produce the video to be displayed on the projector. This video should consist of an object placed four times oppositely. Showing the different faces of the element and also its synchronized movement in case you want to append.
On the internet there are these types of videos for playback. But if you want to recreate your own object, the most comfortable thing is to produce it from the Adobe After Effects program.
Using 3D Warehouse with Google SketchUp you can create accurate three-dimensional images and even other programs like Photoshop allow you to create a 3D street pothole map , just one of many examples.
There are even templates for this where it will only be enough to supplant the image on the screen with the desired object and this will already have the correct dimensions for its holographic projection. Once you have the video, you should proceed to make a professional homemade hologram projector.
It should be noted that the size may depend on the device to reproduce, if it is the case of a telephone it will be small, but if a monitor can be used, a larger hologram can be recreated. The principle is the same, what changes is the size of the projector to be manufactured.
On mobile devices
In the case of the mobile device , four trapezoids should be made 1 cm wide on one side and 6 cm on the other, plus 3.5 cm high. These must be drawn on a CD plastic or glass and then proceed to cut it and obtain the four pieces of the projector.
The next thing to do is to cut it carefully, since in the case of glass it could chip causing damage. In plastic, care must be taken with cutting instruments.
Once the four pieces have been cut and the edges cleaned, proceed to stick on the side corresponding to 3.5 cm, thus forming a truncated pyramid. It is advisable to clean the surface of the pieces well before gluing them and use epoxy glue for this process.
Then a fifth piece must be made which will consist of a square of the same material measuring 6 cm on all sides. Next, this piece will be glued on the 6 cm part of the piece made with the trapezoids, placing it as a cover.
The next thing would be to place the video on the mobile device and place the truncated pyramid on top with the narrow part down, thus obtaining a holographic projection of the element reproduced on the cell phone.
On a Monitor
It is preferable to have a next-generation monitor or a Smart TV, although there is also the option of converting an old television into a Smart TV with Android.
The process is the same, but a projector must be manufactured according to the measurements of the inches of the television and take care that the angle is always 45 ° on all sides.
