  • Cracking Open the Microsoft Kinect

    The Microsoft Kinect is an Xbox 360 peripheral that allows a "controller-free gaming and entertainment experience." Packed with cameras, microphones, an IR projector, and more, the Kinect is Microsoft's answer to the Nintendo Wii remote and the Sony Playstation Move controller.

    Follow along as I crack open the Kinect for a look at the hardware inside.

  • Removing the bottom grills

    Thin plastic grills are mounted on both side of the Kinect. They are held in place with adhesive and plastic tabs. Using a thin metal blade or spudger, you can pry each grill loose from the Kinect's case.

  • Status LED

    The status LED is held to the front frame with plastic clips. You should be able to remove it without breaking the clips.

  • Microphone cables

    Once the LED is disconnected, you'll also need to pull the microphone cable through the frame.

  • IR projector cable

    To remove the IR projector from the metal frame, you'll need to pull the cable through the frame.

    When I was removing the cable, I pulled the cable through from the connector end. It wasn't until after I pulled the cable through, that I find out I could have pulled it through from the other side.
