Device of points of virtual reality Oculus Rift
In the summer of 2012, the Okewlus Rift project collected more than $ 2.4 million at Kickstarter, with the first million being received in just 36 hours. Virtual reality glasses have not yet been officially released, and now (since September 2012), only the option for developers with more modest features than the future full version is available to users. But the stripped-down model for developers is in great demand, the inventor of the device was even forced to notice that those who would like to expect Okjulus 2.0 in 2014.
Virtual reality glasses have a horizontal viewing angle of 90 ° and a diagonal viewing angle of 110 °. The model displacement sensor for developers operates at a frequency of 1000 hertz, while the prototype had a 250-hertz sensor.
On the iFixit website was published detailed instructions for the analysis of points, indicating the technical details and features of operation. The device received a maintainability rating of 9 points out of 10, where a higher value corresponds to greater ease of disassembly and assembly. Before actually using the glasses you need to adjust to a specific user. Included with Okewlus comes a set of three sets of lenses.

With the help of a conventional coin, you can adjust the focal length. A guide from wiki.teamfortress.com can be useful in this case.
Points understood very simply. Inside is the main part of the glasses - Innolux HJ070IA-02D 7-inch screen. Chimei Innolux is the biggest Taiwanese display maker that Apple is rumored to turn on for iPad Mini displays instead of using Samsung production facilities.
The first prototype was assembled on the basis of a screen with a diagonal of 5.6 inches (14.2 cm), but the unexpected success on Kickstarter made the developers think about the availability of a large number of such displays. In the developer version, the display has a resolution of 1280 × 800 (half of each of the two eyes, that is, 640 × 800). In the future full version, the screen will have a resolution of at least 1920 × 1080.
On the back of the display is the Himax HX8851 controller.
Behind the display is a motion sensor board, specially optimized for low delays. The editors of iFixit carefully studied its structure. A STMicroelectronics 32F103C8 ARM Cortex-M3 microcontroller with a 72 MHz processor, a six-axis motion controller (gyro and accelerometer) Invensense MPU-6000 and A983 2206 — presumably, a three-axis magnetometer used for error correction is used.
Interestingly, the contact pads for troubleshooting are displayed at the back.
Okewulus connects to the computer (and at the moment only the PC platform is supported, although compatibility with game consoles is promised in the distant future) with the help of this monitoring device. From left to right: HDMI, DVI, Mini USB outputs, DC input — extra power for working with computers unable to provide the required USB power. On points goes DVI.
Like glasses, the box is easily disassembled. Inside, you can find a board with a Realtek RTD2486AD controller, a 256 KB serial Winbond W25X20CL flash memory module and a Techcode TD1484A synchronous controller
How can I use the trial version of Okewulus for developers? If you often play Tim Fortress 2, then you may have noticed that some players (usually on foreign servers) are wearing a hat in the form of virtual reality glasses. (The bug with the work of both eyes when playing for Demoman is still not fixed.)
Also, you can always proceed with what is expected of you - the development of applications and games for the nascent device. For example, you can write your own simulator of such an interface as a guillotine.
