Homemade Virtual Reality Goggles

The Google Cardboard is one of the simplest ways of encountering Virtual Reality at home. Utilizing this instructional article, you will make one for yourself at ZERO expense on the off chance that you have a few: cardboard, clear plastic, and magnets in your home. I made myself a working DIY Google cardboard from reused materials, that is, even the lens. Sourcing the lens while making VR goggles is one of the most troublesome aspects since it’s not easily accessible and quite pricey. So I made the lens myself by utilizing clear plastic. Follow the guide below and build your own homemade virtual reality goggles at home.

How does it Work?

In this article, you will first get to know the process of making the homemade lens for the VR Headset. And afterward, you will have to create the cardboard inclusion for our DIY Google Cardboard by means of printable templates provided here. The lens used in these VR headsets helps to decrease the least distance of distinctive vision (LDDV) and allows you to observe the screen of your smartphone visibly from a few cms off your face.

Making of Biconvex Lens

Let’s start the process with the lens, then trailed by the cardboard VR enclosure. We will make a Biconvex lens by means of clear plastic bottles and some amount of water. In case you already have the lens for structuring VR Goggles, then you can skip this step. Otherwise, follows the following step by step instructions:

  • The first step is to stumble on an empty clear bottle that contains a good “Curvature.”
  • After this, create a circular template of around 25mm diameter on a sheet of paper or cardboard.
  • The next step is to cut the spherical pieces from the plastic bottle by means of scissors. Try to make and score at least four pieces of this since you’ll need two pieces jointly to produce a single biconvex lens.
  • After this, merge the two pieces of the clear plastic collectively to generate a biconvex shape lens.
  • The next step is to cautiously fasten all the boundary sides of the biconvex shape plastic you just attached using quick dry epoxy.
  • After this, fill your needle with plain water and watchfully insert it inside the biconvex form until you fill it up completely. While inserting water, there might be a chance that you will get some of the bubbles. To remove such bubbles, all you need to do is simply pinch or softly squeeze so that all the big bubbles softly removes.
  • Once you remove all the bubbles successfully, the next task is to fill it up with water and seal it again. Do not forget to seal the hole you just made with the needle.
  • After this, let it all dry for a few minutes. The next job is to test if your lens is able to amplify things properly or not. Check it out by making use of small things like printed letters.
  • Now, replicate the process for your second and last biconvex lens one by one.

One can easily create the lens by following the above-mentioned steps. However keep in your mind, as the size of the lens of the magnifier lens keep on increasing, the magnification power of the magnifier keep on decreasing significantly and vice versa. This is a consequence of the amount of curve in the magnifier (lens). Magnification power is an outcome of the amount of curvature in the magnifier lens. As the size of the lens increases, the amount of curvature in the lens keeps on decreasing, resulting in lesser magnification power of the lens. Similarly, if the size of the lens keeps on decreasing, the amount of curvature present in the lens increases, which results in advanced magnification control of the lens. This is the reason that the higher magnification lenses are usually smaller in size as compared to the lower magnification lenses.

Making of Enclosure for the Google Cardboard VR Headset

Now here in this step, we will make the enclosure for our Google Cardboard VR headset. To complete the process successfully, simply follow the below-mentioned instructions.

  • The first step is to download some templates of your choice and takes it print on a long bond paper in a landscape mode.
  • After this, simply cut down the template by making use of scissors.
  • The next step is to attach the template on the cardboard by using glue.
  • The next job is to slice the cardboard based on the glued template. Once you cut all the three parts of the template properly, the next job is to assemble it. To complete the assembling process successfully, simply follow the markings on the templates and make the required folds.

Attaching the Lens to the Cardboard VR Headset

Now in this step, you need to attach the lens you prepared earlier onto the eye-slot of the accumulated Google Cardboard Headset successfully. To place it correctly on the VR headset, you need to utilize the slots on the cardboard enclosure.

Once you setup everything properly, the next step is to test it by running the VR apps on the smartphone. All you need to do is, download the VR app on your smartphone or the stock Google Cardboard app and load it simply on your phone. After this, place it simply inside the VR headset and view it. By following all this guide, you can easily make a homemade VR goggles without any difficulty.
