Intro: DIY 3D Head-Mounted-Display Using Your Smartphone

I recently stumbled over the OpenDive 3D glasses from Durovis.
Stefan Welker designed this nice little toy and made the plan open source.
It is a Head-mounted display like the Oculus Rift but instead of using a dedicated display you can use your smartphone as a display.

The plan he released is a 3d model for 3d printing.
Today everything seems to be printed with a 3d printer but simple constructions like this do not necessarily need such hardware. I have read that printing this model in 0.3mm layers takes like 6 hours.
Actually this can be easily made from wood or plastic sheets. And actually :)... cutting out the parts by hand took around 1.5 to 2 hours. *WIN!!*
Man beats machine...

So I downloaded the plan, took the measurements and constructed a frame using Inkscape.
Yes, Inkscape. Not very much known for it's technical drawing capabilites but the result is nothing to sneeze at.

My fellow students can confirm that ...

The lenses used in the OpenDive can be bought over at Amazon for 7€.
The kit contains 2 lenses and a headstrap.
The wood and velcro I had laying around but all in all this Head-Mounted-Display can be build for around 10€.

The outcome is not that bad ! At least it helps to fill the time until the final Oculus Rift hits the stores.

YAY !

UPDATE:
29. Dec 2013: 3mm plans have been updated. Edges should now align better.
Added a modified version with bigger viewing window (Better for bigger smartphones)
2. Jan 2014: Updated both 3mm versions (0.2 and 0.2b) to 0.3 and 0.3b. They now have stronger edge reinforcement (headstrap) and a nicer eye divider.

Step 1: The Blueprint

1) OpenDive 3D model meassured
First I loaded the 3d model into Netfabb and took it's rough measurement.

2) Inkscape box maker plugin
Using Inkscape and a plugin called Tabbed Box Maker I first made a box. Then I looked at the 3d model and modified the box in Inkscape.

I have uploaded three versions.
  1. One is for 4mm thick material.
  2. One is for 3mm material.
  3. The last is for smartphones with a bigger screen. Also for 3mm material.
The viewing window is 110mm x 50mm for No. 1 and 2.
No.3 viewing window is 104mm x 57mm. The Edges can be sanded/cut beveled so that the viewing angle is even wider.

For a complete list of PPI's from different smartphones read the Wikipedia article.

EDIT:

1) I have updated the 3mm plan as there were some errors in it. All edges should now align nicely.
2) Added a modified version 0.2b. The viewing frame has been removed so that phones with a bigger screen don't get cut off. Especially Galaxy S3/4-ish phones.

Step 2: Cutting Edge

Next the plan needs to be transfered to the material of your choice.
Print out the SVG on paper and glue it onto wood or cardboard.

In the beginning I tried to use my Laser Engraver to cut through 4mm cardboard from a TV set but realized that 300mW are to weak to even cut through the first layer of cardboard.

Then I simply engraved the plan onto 4mm balsa wood which work out nice and used a fret saw to cut out the parts.

I found some hobby plastic sheets at my hardware store. This stuff is 3mm thick and a rather soft compared to acrylic glass. It can be cut with a knife so I tried my Frankentein Laser Engraver on it.
The result was okay but not satisfying. The laser could cut through the sheet but takes rather for ever. At a speed of 400mm/minute it can engrave nice fine lines. At 50mm/minute it cuts about the 1mm into the material. I tried it at 20mm/minute in one run but it cut merely 1-2mm. I guess several runs at 50mm/minute could cut it but that would be a torture for the laser.
Besides the very hazardous styrol fumes (see wiki on Styrene) that come up when this stuff melts, I really like the material and with some rework and a sharp knife this could be cut as well.

Step 3: Putting It Together

Finally the parts were put together. I used sandpaper to smooth the edges.
When everything fits nice and tight I glued the parts using wood glue.

I decided to cut the lens holder into two and used a rose-head bur to shape a guidance for the lenses.
The lenses were fastened with a hot glue gun.

To fix the smartphone I used velcro. This worked out nice and the smartphone isn't able to slip out.

For the slides were the lens holders go through, cut some piece of foam and pull it over the handles to block out light from the outside.

Step 4: Games - Techdemos - 3D SBS Trailer

So now give me some stuff to do !!!

Here you go...

1) Visit the home of the original OpenDive for games. The range of games is somewhat "managable" but should increase in the next month. Or how about some old school matches Quake 2 in a modded SBS version. Scroll down to get instructions how to get started.

2) Contact Youtube and search for "SBS 3D". A lot of 3D TV manufaturers offer 3D Side-by-Side demo trailers. These are what you are looking for. Don't forget the movie trailers filmed in SBS 3D.
I personally really like LG demo disc 3. All I say is "BASEBALL" ! You will remember we !!!

3) Play PC games streamed to your Android phone. I havn't tried this one yet because my Xperia Sola lacks a gyro. Well how ironic. Anyways, check it out - Kainy

    cant you just use your phones LED and a computer webcam for LED tracking in placement of a gyroscope?

    These days it is very easy to build a low cost VR headset. In the early
    90s it would have cost you a fortune to build such a headset. I built my
    own PC Virtual Reality headset using a 8" 1024x768 lcd screen, a sheet
    of 3x magnification fresnel lense and a wirless air mouse which acts as a
    head tracker. It works great for any PC First Person Shooter or open
    world RPG games like Skyrim, Oblivion, etc.

    Thank you ianmcmill for a very nice instructable. :-)

    I have made a similar Viewer using 2mm sheets of particle board wood which were laser cut to the desired shape.
    For the lenses I have used optical grade +6 diopter reading glass lenses
    which I purchased from my local optician. I also additionally purchased
    +5, +4, +3 diopter lenses (in pairs) which can be used to focus on to
    wider smart phone screens. The +6 diopter is good for up to 4 inch
    screens. I will put up the instructable outlining the steps, shortly.

    On a side note......I
    have also made a glass prism which allows one to see 3D cross eye SBS
    photos and videos on any non 3D monitor or LCD TV. You may wish to
    check it out.

    I just made googles (cardboard) take on the virtual reality world, they also have an app for it! Although my one needs a lot of work i'm going to try your version when i'm back at uni (i'm a product design student)

    Thanks!

    This looks great. Got some 3mm balsa and a pair of 5x loupe lenses I picked up at a local hobby store so I can try this with my Galaxy S3. Hoping I can get a couple junked S4s so I can pull their displays and build a dual 1080p screen setup in the future.

    I asked about this in another post, but, I have a few very nice (and pricey, in their day) handheld video recorders. JVC and Sony micro-cassette type. The screens on them are about 2 or 3 inch square and very high res. Much more so than a smart phone screen. Do you think it would be possible to do the same thing with these types of screens? I would LOVE to give it a shot...

    I'm making this one at the moment. Tip: For the material I'm using pvc
    forex, which is very light weight and strong enough at the same time.
    I'll post some pictures once I'm done

    Hey awesome project. I have built one myself now out if abs plastic and its great!!! :-) A couple of questions though, on your designs I had to change them a bit. The parts that sort of stick out to slot in to the groves (probably have a specific name but I don't know it) they were A) different heights and B) were more than 3mm. This means that when you cut them out they stick out above the main body. To me that doesn't look great. 2nd of all the diameter of the hole for the lens is too big. Now I'm new to all this CNC cutting and design so although i got mine to work in the end you may have designed it intentionally like this I don't know but i thought i would let you know how i got on anyway. Thanks for posting this brilliant build anyway :-)

    P.S: Photos of my build hopefully coming soon

    Thanks !

    Yeah I know about that glitches. They weren't there in v0.2 but found their way into v0.3. Actually I wanted to get rid of them in 0.3 but instead introduced new ones :)

    About the diameter for the lens though I made them smaller then the lens and used a rose-head bur to trim some kind of channeling to hold the lens.

    When my exams are over I will try to fix the irregularities.

    P.S: Photos are always welcome !!
