    • The folks at Oculus VR have had a busy year. Their hard work culminates in an amazing bit of technology, the Oculus Rift Development Kit 2. Features include:

    • Accelerometer, gyroscope, and magnetometer with an update rate of 1000 Hz

    • Positional tracking via external camera with near-infrared CMOS sensor

    • Low-persistence 5.7" Super AMOLED display with a resolution of 960 x 1080 per eye

    • Built-In latency tester

    • 100° field of view (a much discussed change from DK1)

    • All well and good, but DK1 ran away with an impressive 9/10 repairability score when it hit our teardown table in the Spring of 2013. Here's hoping that score holds as the Rift evolves to its newest incarnation. Let's see what's what!

    Any height and width info for the housing?

    • The Oculus Rift Development Kit 2 wouldn't be a complete piece of developer hardware without its assortment of cables, adapters, and accessories.

    • Cable management is a must when you've got a cluster of cables like this. The DK2 features a cable hub that combines USB 2.0, HDMI, DC power (optional), and a Sync cable for the positional tracker.

    • Notably absent from this array of accessories is the control box. It will not be missed, but we're curious to see what other hardware alterations have enabled this welcome sleekification.

    • We have an ocular face off! Development kits 1 and 2 have a staring contest, giving us time for a quick comparison.

    • The first thing we notice is that DK2 shows some noticeable streamlining in size and shape.

    • Without warning, the forefather of VR headsets crashes the party—the Virtual Boy.

    • It's a fight to the virtual death! The contenders weigh in at:

    • 896 g for the Virtual Boy, making it the heavyweight champ (although, to be fair, this was never supposed to hang off of your face)

    • 453 g for the newcomer to the ring, the DK2

    • 395 g for last year's lightweight fighter, the original Rift

  4. Oculus Rift Development Kit 2 Teardown: шаг 4, изображение 1 из 1
    • The DK2 includes a brand-spanking-new positional tracking unit. Essentially, it's a custom-made external IR camera, specially designed to work with the new Development Kit.

    • According to Oculus VR, "it is not possible to substitute an old webcam, nor is it possible to retrofit the tracking to the original Development Kit."

    • The Oculus Rift DK2 retains its 360° orientation tracking, with no camera needed—just like the first version of the Oculus Rift. But to get the added benefit of positional tracking, you'll need to be in the external IR camera's field of view.

    • Positional tracking does what it says on the tin: it tracks the position of your head in 3D space, relative to the sensor. When you lean in to examine a virtual object, the environment zooms in to translate your movement, adding another layer of interactivity and realism.

  5. Oculus Rift Development Kit 2 Teardown: шаг 5, изображение 1 из 1
    • We love our IR camera. Any opportunity to capture that exciting invisible glow, and we're all over it. So when we heard that the DK2 was going to incorporate the IR LED array of the Crystal Cove prototype, but with the LEDs on the inside, we knew it was our camera's time to (catch the) shine once again.

    • With the DK2 fully hooked up and running its demo software, the positional tracking camera starts tracking—with the help of light totally invisible to our eyes, blasted through the black plastic of the front of the headset.

    • MORE DOTS.

    • EVEN MORE DOTS.

    • Tucked away under a rubber cover in the front, we find the USB accessory port and an additional sync cable port.

    • Time to de-face the Oculus: we remove several Phillips #0 screws securing the device itself to its adjustable headband.

    • Within the faceplate, we find two new and improved lenses. The lenses have increased in size to accommodate a wider IPD (interpupillary distance) range.

    it's not a DC power socket on the HMD. IT's a sync port, which is currently unused.

    Right you are—good catch! We've updated that step.

    Jeff Suovanen -

    • After 150 years of development in VR, we have finally found a way to make the Oculus even more realistic... It's like everything's right in front of you, in full 3D!

    • If you own a DK2, using it to watch this video could result in an irreversible recursive cognitive paradox.

    • Thankfully, removing the interchangeable lenses remains a straightforward affair: twist and lift.

    • For those gamers who sport geek-chic glasses, the Oculus team has included different eyecups of varying focal lengths, just like it did in the Oculus VR, though this isn't a perfect solution.

    • With the lenses removed, there is no end to the light-bending experiments we can perform.

    • Naturally we took the opportunity to trap fellow tech writers in a tiny upside-down world! Science is awesome.

    What's the lens diameter and focal length and approximate magnification?

    • This svelte cable cover slides out with nary a complaint, making the Mini USB and HDMI cables surprisingly easy to disconnect.

    • In terms of a model number, these FCC labels yield nothing but "Rift DK2."

    • Simplicity: we can haz it.

    • Keeping up with the Oculus news recently, we figured there might be something lurking within the HDMI cable, just like with Apple's Thunderbolt cable from awhile back.

    • With a couple flicks of our metal spudger, we find we were right—a hidden IC presents itself!

    • We find the Spectra7 VR7100 processor buried under what seems to be a thick encasing of glue.

    • According to their product brief, the little doohickey "reduces size and weight of HDMI copper interconnects..." and "supports video formats up to 4K 60p" — hot stuff!

    • Well now we know why the cables got so much thinner when compared to the DK1.

    • Let's pop open the slick new cable hub and find out what's inside:

    • ON Semiconductor NCP 374 overvoltage protection device with load switch function

    • You can sleep soundly knowing that those cables aren't going anywhere, because Oculus didn't skimp on the globs of hot glue on the inside of the cable hub.

    • We quickly dispatch some serious rubber plugs and go Wolverine all over the screws they protect.

    • With the screws dispatched, we slide the eyewear enclosure out of the front casing.

    • Hold onto your hamburgers, because here comes the first look at the inside of the Oculus Rift Development Kit 2.

    • Opening the treasure chest a bit further, we get a glimpse of a whole entire motherboard, not the tiny boards of yore.

    • But what's all this orange cabling? Looks like we found the many sources of those many, many IR LEDs.

    • There are eleventy nine forty of them, artfully connected via a ribbon cable designed by space elves.

    • We can neither confirm nor deny the existence of space elves.

    • Here at iFixit, we are unabashed lovers of screws—they epitomize everything that's good about repair. Which is probably why Oculus VR sneaked this maddeningly uncooperative non-screw in here, just to mess with us.

    • Actually, this could just be a minor manufacturing snafu. Apart from the lack of threads, this little guy is identical to two other (perfectly ordinary) Phillips screws nearby.

    • If you happen to find yourself disassembling a DK2 in the future, do let us know—we want to compare notes (and steal your screws).

    Could this screw be like this to prevent pcb stress from hdmi connector?

    • We manage to liberate the motherboard from the DK2's eyewear enclosure with ease.

    • This motherboard is a major change from the previous incarnation of the Oculus Rift. All of the device's guts are now packed onto a single board, eliminating the need for an external control box.

    • We've got to hand it to Oculus, because they've really stepped up their motherboard design. It's easy to remove, and quite a looker as well. We'll have to see if this Oculus design can stand the test of time and make it into the consumer model.

    • These are the ICs that make virtual reality a possibility:

    • Toshiba TC358779XBG HDMI Interface Bridge

    • STMicroelectronics STP16CPC26 Low Voltage 16-Bit Constant Current LED Sink Driver

    • STMicroelectronics STM32L100RB Ultra-low-power 32-bit Value Line ARM Cortex-M3 MCU with 128 Kbytes Flash, 32 MHz CPU, LCD, USB

    • Cypress Semiconductor CY7C65632 Very Low Power USB 2.0 Hub Controller

    • STMicroelectronics ST1S31 3A Step-down DC-DC

    • Invensense MPU-6500 Six-Axis (Gyro + Accelerometer) MEMS MotionTracking

    • Texas Instruments TPS65632A Triple Output AMOLED Display Power Supply

    • With the motherboard out of the way, we're ready to extract the DK2's display.

    • The display has a rubber case housed in a plastic backing. Our spidey senses start tingling when we peel off the rubber case...

    • The display is—drumroll please—literally the front panel of a Samsung Galaxy Note 3.

    • This seems to make economical sense, since Oculus is working to ship something like 45,000 DK2s—a goodly number for a mid-development prototype, but certainly not enough to warrant a fully custom display. It looks like Oculus is already taking advantage of their partnership with Samsung.

  16. Oculus Rift Development Kit 2 Teardown: шаг 18, изображение 1 из 2 Oculus Rift Development Kit 2 Teardown: шаг 18, изображение 2 из 2
    • The Galaxy Note 3 display panel that Oculus is using features a 5.7" Super AMOLED 1080p screen.

    • We take a closer look at the display panel, and find that Oculus even left the Synaptics S5050A touchscreen controller intact.

    • Maybe they're planning on releasing an eyelash touchscreen controller add-on later.

    • Oculus claims that the DK2 display is a low-persistence OLED screen capable of a 75 Hz refresh rate. This means that Oculus is overclocking the Note 3 display panel from its stock 60 Hz, which results in smoother motion.

  17. Oculus Rift Development Kit 2 Teardown: шаг 19, изображение 1 из 2 Oculus Rift Development Kit 2 Teardown: шаг 19, изображение 2 из 2
    • We may have exhausted the headset's goodies, but this teardown ain't over yet. We turn your attention now to the positional tracking camera.

    • The DK2 positional tracker's stand has several articulation joints and a tripod mount so you know it will always be there for you, bending over backward to help.

    • The positional camera itself is attached to its stand with two small clips. Once detached, we're free to crack it open to find the real goodies inside.

    • We take off a filter that we guess blocks visible light, allowing only IR light into the camera.

    • We use some high-tech hacking to prove our theory: tape, a cellphone, and a remote control.

    • Voilà! Visible light filtered out, IR beam clearly shining through. Visual victory!

    • A sneaky cover plate hides a couple screws on the positional tracker's body, but our opening pick quickly sniffs them out.

    • The promising seams along the side are not for prying—ignore them. Ignore them well.

    • Once inside, the positional camera's motherboard and lens assembly are removed with ease.

    • We quickly dispense with two more screws, and then pop the lens assembly off the motherboard.

    • After playing around with the positional camera lens, we conclude that it's a wide angle lens. This allows the positional camera to see more IR LEDs at once, expanding its tracking abilities.

  21. Oculus Rift Development Kit 2 Teardown: шаг 23, изображение 1 из 2 Oculus Rift Development Kit 2 Teardown: шаг 23, изображение 2 из 2
    • Upon freeing this baby motherboard from its enclosure, we spy the positional camera's CMOS image sensor.

    • There are several ICs on the positional camera motherboard:

    • Microchip Technology 24AA128 I2C CMOS Serial EEPROM

    • SIWARD 12.0 4C Crystal Oscillator

    • S033 HVG 107Y

    • Etron Technology eSP570 webcam controller

    what model number is this CMOS sensor?

    *rofl* about that eyelash controller, good one! ^^ love to see how cleverly market-ready products such as the Samsung display unit are included.

    Besides a front-facing stereo set of cameras for AR, I think an eye tracker would make sense. While its output would not affect the perspective, software might make use of knowing where you are currently looking.

    That product is on its best way to become a must-have toy...

    The CMOS-Image sensor seems to be an APTINA MT9V034. https://www.aptina.com/products/image_se...

    what is that 4 pin connector for ? next to the SIWARD 12.0 4C Crystal Oscillator

    It is connected to what appears to be an infrared receiver (like this one over at SparkFun). The sensor is visible in the 2nd image of step 21.

    • The Oculus Rift Development Kit 2 Repairability Score: 9 out of 10 (10 is best)

    • Given that the Rift is still a beta product, this is still a preliminary score—but things are looking good, and we hope the consumer version is just as repairable.

    • Standard Phillips #0 screws are used in both the headset and positional tracker, making it a cinch to open them.

    • Cable management is much improved from the original development kit, and the elimination of the control box makes for a simpler, more streamlined device.

    • The use of a common smartphone display means that replacement parts are readily available!

    • Getting into the positional tracker without a repair guide is a bit of a doozy. Prying around the edge won't help you here, but a thin tool in the front will.

    Hello everyone, can anyone please tell me what each of the 14 parts would be called in the picture of the complete breakdown? I understand if I sound a bit silly, but I am just trying to be completely thorough. Thank you very much!

they should give it two 5mp cameras in the front.. augmented realities.. the possibilities are endless..

It'd be fantastic to have stereo camera and microphones on front, and speakers on the head band, so that I could use this device to watch and hear what's going on around me. Non of that virtual or augmented reality stuff, just pure reality - in real time! I could finally go outside and just enjoy watching and hearing stuff.

"What's the lens diameter and focal length and approximate magnification?"

I am also interested in this information.

Diameter and focal lenght. And perhaps the distance between the middle of the lens and the surface of the screen.

Tobias Claren - Ответить

I think, it could also useful for "cardboard" (Google) experiments.

I will order some lense, but I am indecisive which diameter etc..

For cardboard the Google guys says 1" (25,4mm), But this is only the durovis dive lens kit.

that must not be the best. At SurplusShed I can decide between many diameters and focal points.

If we had the diameter, focal pint, and if possible the other data like lens (middle) distance to screen, Eye distance to lens (middle) etc. we could "tinker" a cardboard version for Android based on the oculus rift measurments.

Tobias Claren -

Quick question for you guys. You know how the unit has the adjuster knobs for moving the display further or closer to your eyes? When I first went to put my DK2 on and I pulled the straps back, the left side of the unit pulled back with it while the right side stayed in place.

It's not a major issue since I just adjusted the knob back appropriately, but since then I've noticed that the left knob is no longer in perfect alignment with the hashmarks. On the furthest setting, the knob sits further back than the last hashmark, while on the right side it won't go any further than that.

Is there any way I can easily fix this and get the HMD back in its proper alignment? It's only off on the left side by a few centimeters, and it does cause a noticeable blur problem on the left side of my vision unless I tilt the entire unit, which can become uncomfortable.

Muffy Tarkin - Ответить

Why is that you said it has an magnetometer, although there is no mention of it’s chip-set ?

mahdi rafatjah - Ответить

The DK2 schematic is open source and you can see it here: https://github.com/facebookarchive/RiftD...

The magnetometer is on page 4. Although the magnetometer is in the electrical design, it is not used by the software,
