it's been just over a year since we saw
an oculus rift on our teardown table
back then we were thrilled with the
repair ability of the device giving it a
9 out of 10 on the repairability scale
but we were slightly disappointed using
it the images seemed pixelated and hard
to focus on and the rift had a tendency
to make those susceptible to motion
sickness have a good portion of their
day ruined after wearing it for a few
minutes well even with our
disappointments we're huge fans of the
potential of this virtual reality device
and we're more than excited to have a
second-generation developers unit in our
hands so let's tear it down
hi I'm Gwendolyn with iFixit and today
we take a look inside the brand new
oculus rift dev kit to keep in mind this
device is a developer's unit and many
things may change before it hits retail
but we love the technology and couldn't
wait that long to get a peek at what
makes this thing tick first we check out
the many pieces that come with our dev
kit including cables adapters a
positional tracker 2 different size
lenses and the headset itself with more
cables the most notable difference in
the gear is the inclusion of this brand
new proximity sensor this is a
custom-made IR camera that is specially
designed to work with the new
development kit if you're hoping to add
this with your old oculus you're out of
luck just like the previous version the
oculus rift retains its 360-degree
orientation tracking with no camera
needed but this new version also offers
the addition of position tracking that
requires being in front of the cameras
view turning our attention to the
headset we note that while smaller than
the first revision the oculus 2 weighs
in at 453 grams 58 grams heavier than
the last version we had heard that the
dev kit 2 would implement the LED array
seen in the crystal code prototype at
this year's CES so with our development
kit fully up and running we broke out
our IR camera to give us a peek at all
the infrared lights shining through the
front of the headset I'm sure we'll get
a better look at these soon inspecting
the headset for a weigh in we took a
peek under the front port cover where we
found a spare USB port and a DC in power
socket the screws to get this thing
apart were found on the other side so
all that stands in our way are a couple
of phillips 0 screws next up we removed
the interchangeable lenses no tool
needed for this
just a little twisting and they're off
the oculus rift ships with two sets of
lenses allowing for some personal focus
calibration once we remove the HDMI and
mini USB cables we're able to slide the
eyewear out of the infrared LED hood
this case is packed with a ton of
infrared LEDs a ton being 40 and now we
get our first look at the motherboard
and all the goodies it holds chips of
note on the board include the in
Vincents MP 65 6 access gyro and
accelerometer the Toshiba HDMI interface
bridge and the STMicroelectronics arm
cortex-m 3 MCU which has 128 kilobytes
of flash and a 32 megahertz CPU we found
the display in a plastic backing and
encased in a suspicious rubber case a
little peeling later and it's revealed
that the display is actually the front
panel off a note 3 literally display
cables and yes oculus even left the
touch screen controller impact so if you
crack the screen of your Note 3 and you
need a replacement take a look inside
your oculus rift this is a 5.7 inch
Super AMOLED display that oculus claims
is capable of a 75 Hertz refresh rate
and a 960 by 1080 resolution for each
eye this means that oculus is
overclocking the note 3 display panel
from its original 60 Hertz next up we
turn our attention to the positional
tracker the camera itself comes off the
stand with just a snap removing the
filter that allows only IR light into
the sensor was easy enough and then we
were able to slide off the cover plate
that hides the screws to get inside all
that's left of the positional tracker is
a small board and the lens we've come to
the end of our teardown which means it's
time to talk repairability and iFixit
it's our mission to teach people how to
repair everything so we give every
gadget we tear down a repair ability
score between 1 and 10 10 being the
easiest to repair and one being the most
difficult the oculus rift dev kit tube
got a 9 out of 10 and here's why
standard Phillips 0 screws are used in
both the headset and positional tracker
making it a cinch to open up cable
management is much improved from the
original development kit and the
elimination of the control box makes for
a simple more streamlined device
the use of a common smartphone as a
display means the replacement parts are
readily available keep in mind this is a
preliminary score even that the rift is
essentially a beta product and that's
our teardown for the complete teardown
