How to DIY a Google Cardboard (Virtual Reality) VR Headset?

Google Cardboard offers immersive virtual reality in a fun, affordable and simple way. You don’t have to spend quite a lot of money just to have your own google cardboard. Recently, Google introduced DIY VR with a few essential tools and in the comfort of your own home. So how do you get started?

Steps for DIY VR

In no more than 3 hours, people were able to build their own virtual reality viewer. Do you also want to successfully create your own? Here’s what you’ll need, along with some important tips and tools to get it right.

1.The accessories you will need

  • PDF file from Google cardboard
  • At least two cards
  • lenses
  • magnets
  • velcro
  • rubber band
  • Art knife
  • Double-sided adhesive
  • Shears

It is recommended that you use a suitable type of cardboard, the same thickness as the sturdy shoe box. You can use a pizza box, but make sure it provides enough flat surface to work with. Of course, you need something durable yet slim to work with. In some cases, a few additional items may be needed, such as a ceramic disc magnet, a neodymium magnet, a few pieces of Velcro, a large rubber band, and objectives of at least 45mm.

2.How to assemble accessories

  • Download the compressed templates folder from Google .
  • Print the desired design files.
  • Cut out the design and stick it on the cardboard.
  • Fold the google carton.
  • Set 2 lenses.
  • Now is the right time to place the neodymium ring-shaped magnet and ceramic disc magnet.
  • Put on 2 regular strength Velcro strips with glue.
  • Buy an eraser now to avoid your smartphone slipping out of the Google carton.
  • If necessary, stick the NFC tag to the carton.

If you’re building your own google cardboard, we found that the DC01 magnetic disk inside works fine with the RA22CS-N on the outside. You can also use a disc magnet with a similar size DA01 inside.

Step 1: Things You’ll Need

Here’s what you need to get started:

1. Cardboard: – A sheet of corrugated cardboard, preferably E Flute (corrugated cardboard is available in a variety of thicknesses known as “waves”), available from many art supply stores and online. For best results, look for strong, thin cardboard (rather than a movable shoe box). Minimum size: 8.75 inches (22 cm) by 22 inches (56 cm) and 0.06 inches (1.5 mm) thick.

2. LENSES: – This is the most difficult part. 45mm lenses can work. Biconvex lenses work best because they prevent distortion around the edges. We used the Durovis OpenDive Lens Kit available on Amazon.com

3. MAGNETS: – One neodymium ring magnet and one ceramic disc magnet – this or that. Approximate size: 0.75 inch (19 mm) in diameter and 0.12 inch (3 mm) thick.

4. HOOK AND LOOP: – Two normal strength Velcro strips with adhesive. Approximate size: 0.75 inches (20 mm) by 1.25 inches (30 mm).

5. RUBBER: – One rubber band to prevent the phone from slipping out. A minimum length of 3.2 inches (8 cm).

6. NFC TAG (OPTIONAL): – One NFC tag sticker. Program it with url cardboard: //v1.0.0

7. You will also need a ruler, glue and scissors, an X-acto knife or access to a laser cutter (not shown in the picture above)

Step 2: Download the Template

You don’t actually need to design it. The design files are now available here – https://drive.google.com/file/d/0B5csX2CytQ0VNlY1d.

Now follow the procedure below to create your own VR viewer :-

First, open the .zip file you downloaded from the website (in step 2) and double-click cardboard.pdf.

Second, print the template (cardboard.pdf) in color by clicking File> Print in Adobe Reader or other software.

Third, glue the template to a piece of cardboard (mentioned in step 1) and, once dry, glue the light numbers over the dark ones.

Fourth, cut the cardboard along the black lines. Do not cross the “RED” line. Also cut the boxes with the black line using the X-acto knife.

The bottom photo shows a fragment of the Viewer Case that I cut out of a pizza box with a knife and a ruler. The stencil paper is still stuck to it.

Google I / O replaced the Google carton, I always want to get it, because of its low price, the device has a virtual reality feel. Unfortunately, not buying google cardboard was driving me crazy. So I decided to do the same myself. I just need some tool :

1. You can download the Google Cardboard PDF, printed in A4 format, from https://developers.google.com/cardboard/

2. Cardbaord, maybe two.

5. Double-sided adhesive

Either way, build this headset in the case about 1 hour. I found it really fun, I love this cardboard idea! Hopefully more guys will be able to enjoy VR games, movies, street views, etc. That’s why we’re publishing non-office google cardboard on ElecFreaks. Just $ 9.98 to get one, http://www.elecfreaks.com/store/unofficial-version.

A weak magnet is glued / glued on the inside of the cardboard. Outwardly, the ring-shaped neodymium magnet is attracted by the cardboard to the first magnet. While sitting in the socket, the user can move the outer magnet slightly downward and it snaps back into place when released.

Templates and tools

To get started, print the PDF templates for the Cardboard portion of the goggles onto three 8.5 x 11 inch sheets of paper. There is a template in the photo for the largest part (which I call the browser case). It is divided into three parts on the prints and you need to combine them into one like I did here. The second main template is for the part that I will christen the lens holder, and the third is for the vertical partition.

At this point, I realized that Google doesn’t provide specific tips or practical tips on how to use these templates to cut parts out of cardboard. So I had to think about what would be the best way to cut these parts out of my newly salvaged pizza box.

It turned out that I needed five key tools: a ruler, masking tape, glue stick, multi-purpose knife and X-Acto knife. I used a utility knife to make long cuts in cardboard, while the X-Acto knife was used to make cuts that require more precision (such as corners, curves or narrow slots) and to cut patterns. For me, it was an absolute necessity to have both types of knives on hand, as well as a ruler to help each knife make long, straight cuts in cardboard or paper. (Google calls the print plans a “scissor stencil,” which made me laugh. After a cursory glance, I could tell that they couldn’t be cut precisely with most scissors.)

Cutting and gluing the templates

Next step: cut out the templates. I strongly advise you to cut out the templates from sheets of paper on a large, stable table surface, which is secured with a few sheets of newspaper. I cut out both my templates and pieces of cardboard on the tabloid-format copy of the weekly that had been unfolded.

After carefully cutting the templates with the X-Acto, I pasted them onto the bottom inside of the pizza box with a glue stick. The fully assembled template for the Viewer was longer than the length or width of the pizza box. So I divided this template into two parts, concluding that I could connect the individual pieces of cardboard with masking tape.

The third and smallest element of the Cardboard goggles is what I call a vertical baffle. Here I finish cutting its edge exactly. The finished piece looks in the upper right corner.

How can I buy one?

Google has joined the retailer community that has formed around Cardboard by establishing the “Works with Google Cardboard” tag for partners and placing their viewers on the official website. Many companies sell these goggles as fully assembled headsets, ready to use out of the box, while a few offer laser cut cardboard kits that can be assembled. They even customize headsets with added perks or use the highest quality materials to give viewers stronger, less DIY-looking.

The basic headset is available at different prices from different retailers. The unofficial version of Cardboard sells its v2.0 viewer for an assembled $ 20, and the sliding-lens version modified above has the same price. I Am Cardboard, on the other hand, has a couple of options, including the entry-level v1 viewer for $ 15, the v2 viewer for $ 20, and the $ 30 EVA version of the original viewer. And DODOcase has a kit for its custom viewer that adds a capacitive touch button, for $ 30.

This is the Knoxlabs Aluminum VR viewer. It certainly looks fancy, but it will give you $ 85.

Some companies are starting to deviate from the standard form to create custom designs that still meet Google’s standards. The C1-Glass from Go4D is a plastic lens clip that attaches directly to your phone, and for $ 22, it’s a more compact way to take your VR with you. And Knoxlabs has a $ 85 aluminum and wood viewer assembled as shown above. It’s a nice investment.

Should I make one?

Do you want to do it yourself? Google provides the plans, but you’ll need a few extra parts besides the decent cardboard.

If you have a flair for creation, you can enjoy assembling and even customizing your own Cardboard headset. Google provides instructions on how to cut the headset bezel by hand, and even laser cut if you have access to the hardware. On the first front, if it’s not too greasy, the pizza box should provide enough material with a flat surface to work with. You need something strong – yet slim – to get the job done.

However, you do need a few extra items: a neodymium magnet and a ceramic disc magnet, 45mm biconvex lenses, a few pieces of Velcro, and a large rubber band. Not sure what it is all about? Now that the second-generation browser has been discontinued, Google’s partner companies are starting to move away from selling unassembled browsers and components; but luckily I Am Cardboard still has a set of parts (aside from the cardboard itself) for $ 10. Or, you can just order lenses or magnets separately for a few dollars apiece on eBay.

Notes & Conclusions

If you’re building your own google cardboard, we found that the DC01 magnetic disk inside works fine with the RA22CS-N on the outside. You can also use a disc magnet with a similar size DA01 inside.

If you have a different phone model, you may need to experiment a bit. When the magnetic sensor is in a different position, it may be necessary to change the position or size of the magnets. Overall, we found that the successful operation of the switch is less than 100%. Some of us found it harder to get started than others.

You can build your own cardboard using online plans. You just need lenses and magnets. We bought the lenses on Amazon using the link suggested by Google. For magnets, both magnets can be obtained from us at www.kjmagnetics.com.

Many places have kits that will save you the hassle of cutting cardboard, usually in the $ 20 to $ 25 range.

Can you use iPhone with the device? Not yet. At the moment, there is no iPhone app that works with it. There are several apps for the Oculus Rift, a commercially available 3D goggle product that is a bit more polished than cardboard. However, the two are not compatible. We found that the distance between the two images on the screen is different, so you can’t really use the Google Cardboard design with the apps we tried from the iPhone app store. So there’s probably something you can do, but the Google Cardboard Project won’t work with these apps out of the box.

Thanks to virtual reality goggles, they do not display two superimposed images on the movie screen and then filter it. Since the screen is right in front of your face, it’s just split into two different screens. Each half is for each eye, without any fancy filtering.

Making DIY VR Headset/Google CardBoard:

Google provides a printable template and building materials to create your own VR goggles at home.

  1. A piece of cardboard (at least 22 “x8.75” inches)
  2. 2 inch Velcro straps 3/4 inch wide
  3. One 1/2 inch Neodymium ring magnet
  4. One ¾ ”inch ceramic disc magnet
  5. Two biconvex lenses (45mm approx focal length).
  6. One eraser and NFC tag (optional)

Making Headset:

  • First, download the production kit from google and unpack the zip file into a folder.
  • Open the template and print it.

  • Use scissors and a scale to remove the extra paper from the template, and use glue to connect the parts of the main template with the numbers.
  • A total of three templates are available: body, lens mount, and lens splitter.
  • Then stick the template on the cardboard with glue or glue and leave it for a few minutes.
  • Now comes the hardest part, which is cutting every smallest gap in the cardboard with a fine knife. This restriction will take around 30-45 minutes as smaller cuts will require more focus.
  • Once you’ve finished cutting the cardboard, it’s time to start putting the pieces together
  • Now insert both lenses into the eye openings (note their orientation). See the template for information. Bend the upper and lower parts to prevent the lenses from falling.

Creating a VR headset at home

Tip: use a steel scales to help you make sharp and straight bends.

  • Place the magnets in their places with superglue and start folding.
  • Insert the lens holder with the divider and grasp the cardboard frame around it. Use glue to stick the folds together.
  • Finally, add the Velcro on the top of the flap that will be used to insert the phone into the VR headset.

Your VR headset is now ready and you can start using it by downloading the Cardboard app from Google Play.

Please note that this is not compatible with larger phones i.e larger than 5 inches.
