IFIXIT TECHNICIANS got their hands on and disassembled a second generation Oculus Rift virtual reality (VR) headset this week, awarding it an impressive nine out of 10 repairability score.

Good news for gamers eagerly awaiting the next generation VR technology, the iFixit team said that the Oculus Rift development kit 2 (DK2) is a doddle to repair if something goes wrong.

"The DK2's excellent [nine] out of 10 repairability score meant we didn't break the device and incite a riot. But truly, we're more excited about all the fun stuff we found inside, including the 40 infrared LEDs you see in the image above," said the iFixit team in its latest post.

iFixit said that the first thing it noticed when taking apart the Oculus Rift DK2, apart from the Super AMOLED Full HD display being that of a Samsung Galaxy Note 3 with 1920x1080 resolution, was that it showed some noticeable streamlining in size and shape when compared to its predecessor, the Oculus Rift DK1.

"A Spectra7 VR7100 processor is 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'. Well, now we know why the cables got so much thinner when compared to the DK1," iFixit explained.

The handymen also said that they found 40 IR LEDs connected via a ribbon cable to the motherboard inside the Rift DK2 "probably designed by magical space elves", but said the major reason why the headset received such a good repairability score is that it is mainly kept in place with screws, which make it much easier to fix.

As for the Samsung Galaxy Note 3 display, iFixit said that Oculus must be overclocking its display panel from its stock 60Hz, as the VR headset maker claims that the DK2 display is a low-persistence OLED screen capable of a 75Hz refresh rate.

"We take a closer look at the 5.7in Super AMOLED 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," iFixit added.

iFixit managed to remove the positional camera's motherboard and lens assembly "with ease" and pop the lens assembly off the motherboard with two screws.

"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," said iFixit.
