Oculus Rift's Developer's Kit 2 (DK2) exhibits techniques for lightening weight while improving cost and function. Yes, those are common goals in electronics. iFixit, the fix-it-yourself web site that also sells tools for fixing electronics, also looks at "repairability" -- how easy a device is for the average person to repair. iFixit found Oculus Rift Developer's Kit an easy target. It's relatively simple to get into and poke around, hence iFixit gave it an enthusiastic 9 on its repairability scale with the caveat that this was the beta version of the kit.
The guts of Oculus Rift include, says iFixit:
- Accelerometer, gyroscope, and magnetometer with an update rate of 1000 Hz
- Positional tracking via external camera with near-infrared CMOS sensor. The tracking unit in DK2 is new and custom-made. (Not your old web-cam, in other words.)
- Low-persistence 5.7" Super AMOLED display with a resolution of 960 x 1080 per eye; The display is the front panel of a Samsung Galaxy Note 3, which iFixit says is a great way to save some money.
- Built-In latency tester
- 100° field of view (iFixit says this is a much discussed change from DK1)

iFixit round these semiconductors:
- Thanks to the Spectra7 VR7100 iFixit found tucked into the cable, DK2 has thinner cables.
- ON Semiconductor NCP 374 is in cable hub, providing overvoltage protection device with load switch function
- Motherboard has:
- Toshiba 358779XBG 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,
- Y405 1S31,
- Invensense MP65 Six-Axis (Gyro + Accelerometer) MEMS MotionTracking,
- Texas Instruments SEM TI 39 CF5I Single Schmitt-Trigger Inverter
- These ICs are on the positional camera motherboard:
- Microchip Technology 4AI28I 40615P
- SIWARD 12.0 4C
- S033 HVG 107Y
- Etron Technology eSP570 webcam controller
"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,Ē says iFixitís review
Maybe someday we'll al be viewing teardowns in 3D through the Oculus Rift. (Hey, boss, let's do live 3D teardowns. Might be as exciting as watching CSPAN.) Until that day, we'll just have to do the quick recap and send you off to iFixit for more info.
