    : 手順 1、 1の画像 1
    • We finally have Microsoft's entrant into the realm of motion gaming, the Kinect. Microsoft's code name for Kinect was Project Natal.

    • This isn't just another Wiimote knockoff. Kinect is the result of hundreds of millions of dollars of research Microsoft has invested in speech and motion recognition.

    • The Kinect is not a handheld game controller like the Wiimote or the Playstation Move—rather, it is a sophisticated sensor suite that detects your position and movements in 3D space.

    • There are several great stories already out there explaining how Kinect detects motion. We aren't going to repeat all the basics here, so if you are interested in that sort of thing check out the above articles.

    • Controller evolution, game console style.

    • Top to bottom:

    • Original Xbox Controller S, Kinect

    • Nintendo Virtual Boy, Wiimote

    • Original Sony PlayStation controller, PlayStation Move.

    • We love that the world is at the point where we're not upgrading our computers as often. Instead, we're upgrading sensors so the computer understands more about us.

    • Adding Kinect to an Xbox is like adding sonar to a submarine—sure, you could drive it around before, but now it can see where it's going. OK, that's a rather stretched analogy. You get the idea.

    Why did you choose a Virtual Boy controller? I think the NES controller belongs there.

    Tom - 返信

    It was convenient. We didn't have an NES controller laying around, but we did have the Virtual Boy controller from our teardown in August.

    You kindly forgot the original EyeToy for the PS2. It even had a game called Kinetic.

    • There's a rubber pad between us and the insides of the Kinect. Let's take care of that...

    • The motorized base can rotate the top sensor bar to track you as you dance around the room. That sounds useful, but we're wary of mechanical parts that are prone to failure.

    • The plastic base is secured with a quartet of T6 Torx screws.

    • After removing the plastic base, there are another four Phillips #0 screws to remove.

    • Notice that Microsoft's already up to revision H. If this is launch day, what happened to revisions A through G?

    • The Kinect's motor and gears don't appear too robust.

    • About the size of an American quarter, the base has a tiny motor with three fragile plastic gears. Barring overheating issues with the top unit, we're guessing this motor assembly will be the Kinect's weak point.

    • Do not physically force the Kinect into a specific position—allow it to automatically calibrate its aim.

    Fragil is a difficult word to use when refering to plastic gears, for some/most applications outside of industrial use, "plastic" is a better choice (plastic is in quotes to denote that most gears are a composite material, not usually a specific variatal unlike a soda bottle).

    There is a small golden part with a thing plastic divider that falls out from the Kinect, it doesn't show anywhere - where you should place it from that screen shot.

    • With a metal spudger and some pretty serious prying, we were able to remove the bottom grille. This is not easy, as Microsoft applied adhesive quite liberally.

    • The Microsoft team built the Kinect around PrimeSense's Reference Design.

    • Microsoft hasn't acquired Primesense yet. This indicates to us that as impressive as the hardware is, Microsoft's software is doing the heavy lifting, turning the sensor bar's array of data into a 3D mesh of your spatial position.

    • Microsoft used T10 Torx security screws. That's not very nice. We're up to three types of screws already, and we haven't even got this open yet.

    • The innocent looking Xbox 360 sticker acts as cover for the third screw on each side of the Kinect.

    some kinects have different torx security screws, because in my kinect, the torx have 5 "sides" and not 6 like normally, so, how do I get that open???

    • Success! Now the fun really begins!

    • Most of the Xbox's processing power is dedicated to gaming, so Kinect preprocesses the image prior to sending it on to the Xbox. Kinect condenses all the information it collects about your living room into two things: a color image and a depth map.

    • Kinect's slim form factor has forced Microsoft to split up the main board, stacking three boards vertically like a small apartment building.

    • There's a fan at the far end of the Kinect. It's aligned to suck air in one side of the Kinect and push it out the other.

  10. この手順は未翻訳です。 翻訳を手伝う。

    : 手順 10、 1の画像 1
    • We've finally found the Kinect's eyes.

    • Two cameras and an IR projector.

    • Left: (IR CMOS) Microsoft / X853750001 / VCA379C7130

    • Center: (Color CMOS) VNA38209015

    • Right: (IR Projector) OG12 / 0956 / D306 / JG05A

    • This picture is of the device upside down, so these labels are swapped from what you would see looking at the Kinect.

    • These are not tiny, cell-phone cameras— they're closer to the camera you might find in a webcam, with large lenses and autofocus.

    • We can't independently confirm the resolution of the cameras yet, but Microsoft claims that the infrared cam is 320x240 and the RGB cam is 640x480.

    For the IR emitter, are these part numbers that are listed in the article? If so, where did they come from? I googled for them, and can't find anything. I know the grating in front is custom, but I would be interested in the data sheet for the emitter.

    • This is a Prime Sense diagram explaining how their reference platform works. The Kinect is the first (and only) implementation of this platform.

    • One camera (and one IR transmitter) provide input for the depth map (rumored to be just 320x240), while the third camera detects the human visual spectrum at 640x480 resolution.

    • We have heard claims that the system can measure distance within 1cm of accuracy at two meters. While that's great in concept, early reviews are showing that you don't get anywhere near that accuracy in the real world—yet.

    • All four microphones connect to the motherboard with a single cable connector.

    • After removing three connectors and seven T10 Torx screws, the top board can be separated from the other two boards.

    • The brains of the Kinect. The folks at UBM TechInsights helped us identify many of these chips. You can see a high resolution scan of this board here.

    • Wolfson Microelectronics WM8737G - Stereo ADC with microphone preamp

    • Fairchild Semiconductor FDS8984 - N-Channel PowerTrench MOSFET

    • NEC uPD720114 - USB 2.0 hub controller

    • H1026567 XBOX1001 X851716-005 GEPP (Help us identify this 6 mm x 4.9 mm SAP package. Possibly SPI flash, maybe Atmel?)

    • Marvell AP102 – SoC with Camera interface controller

    • Hynix H5PS5162FF 512 megabit DDR2 SDRAM

    You're missing the back-side images of this board & the next one.

    For a moment I was confused and thought the next image was the back of this one. I couldn't see how the boards attached (electrically) to each other.

    Looks like the Kionix 3 axis accelerometer chip uses either the old 4-wire serial bus SPI or I²C (Inter-Integrated Circuit) to send the tilt and inclination data.

    Basically it is a fancy digital carpenter's level, unless they are also using it for image stabilization with all the jumping going on in the living room ;)

    • Here we discovered three of the four microphones inside of the Kinect.

    • There are a total of four downward facing microphones: three on the right side and one on the left side.

    • Microsoft determined that the best orientation for optimal sound gathering would be downward facing.

    • In order to properly recognize voice commands, the Kinect must perform an audio calibration for the room that its in. However, if you alter the arrangement of the furniture in your room, you must re-calibrate.

    • This board is held in place by four standoffs. We used needle-nosed pliers, but a 5 mm nut driver would be the right tool for the job.

    • Our friends at Adafruit have posted a $2,000 bounty for the first team to write an open source driver for Kinect. The Wiimote has been tremendously useful for our hobby robotics projects, and the Kinect's advanced sensors could really jump-start robotics research.

    • Finally! We're able to remove the power/data cord from the shell of the Kinect.

    • Microsoft is using a USB-like connector for the Kinect. The Kinect uses 12 watts, which is quite a bit more than 2.5 watts of power provided by a standard USB port.

    • In the midst of an array of complex sensors and transducers, we remove the status indicator LED.

    • After removing several more screws, the two cameras and the IR transmitter easily lift off the metal backing bar.

    • Another component is sandwiched between the IR Projector and the metal backing bar. This is likely a Peltier Device used for cooling the IR projector.

    • The two cameras and the IR Projector, side by side.

    • By having the depth-of-field camera and the RGB camera a calculated distance apart, the Kinect is able to perform immediate, 3D incorporation of real objects into on-screen images.

    • Having no form of user input other than voice commands and gestures, the crux of the Kinect's input system is the sensor system, comprised of the microphones and cameras.

    Note that the depth-sensing camera appears to use a screw-in manual focus lens, while the color camera has an auto-focus mechanism for its lens. This is probably because the depth image only needs to be good enough for the image processor, while the color image will be seen by users (and MS wanted it to be nice & sharp).

    Also note that the "IR projector" is actually an IR laser with a diffuser over it that creates a random-dot pattern all over your living room (search YouTube: Kinect night vision). The depth camera is used to measure the dot displacement (from its known pattern) to calculate the depth over the image (WIPO Patent WO/2007/043036). A laser is required so that the projected pattern is always in focus. Since the projector is a laser, I'm guessing that its flex cable has safety features to shut it off as soon as you start taking apart the Kinect's housing.

    • Our Kinect is now fully disassembled.

    • Shameless plug: We now sell parts for game consoles! Our Xbox 360 RROD fix kit or PS3 YLOD fix kit can breathe new life into your dead or dying console.

    • Microsoft Kinect Repairability: 5 out of 10 (10 is easiest to repair).

    • The design is very modular, and replacing individual components (like the motor) when they fail shouldn't be a problem.

    • No soldering required to disassemble.

    • Although modular, disassembling one of these can be difficult due to the sheer number of bits and pieces.

    • Microsoft used four kinds of screws, including some hated security bits: T6, T10, T10 security, and Phillips #0.

    • Without a service manual, repair will be quite a challenge. Microsoft has not made a service manual available. If we get enough demand, we'll do their work for them and publish one.

Who makes the cameras?

I wish there was a service manual ! Bought my Kinect more than a year ago, used it 3-4 times. Today I took it out from the dust, and it doesn't work anymore, error 2c, and nothing seems to come out of the rgb cam :(

BEWARE of the 3 tiny washers/spacers in the base of the Kinect, that are not mentioned in the breakdown anywhere. I'm still trying to figure out which side of the gearsets they actually go on. Best practice to avoid the situation I'm in would be to unscrew the 4 philips screws and take the base off with the Kinect in the upright position, maybe you'll have better luck!

actually there are 4 tiny washers

what element is responsible for checking kinect temperature?

Arek - 返信

i took apart the cameras and ir blaster.

quite interessting.

IR Blaster:

its very simple. On the outer rubber sleeve is a thermo sensor

the main component is a IR Laser Diode with a lens behind a diffraction grating.

undeaneath the Laser is a TEC / Thermo Electric Cooler to stabilize the temperature and the wavelength.

https://i.imgur.com/xfOYVNN.jpg

IR Camera

a specially coated lens which is quite big inside, behind that a IR pass filter and then the sensor. Looks like a CCD but quite a big one, large pixels = more sensitive.

https://i.imgur.com/lmk8HUG.jpg

Visible light camera:

well just a normal camera module. with a IR cut filter of course.

notice the die size, or the pixel area is much smaller.

Would it be possible to recycle any of the components into a new project? I’m a 13 year old tinkerer, and I just got a NodeMCU esp8266, so I’m kind of on a tinkering spree.
