If you're curious about what's inside this sleek little gadget, here's a summary courtesy of iFixit:
* Four microphones. Four! We've taken apart binaural devices before, but this is our first quadaural sensor setup!Want to know more or see the step-by-step teardown? Hit the iFixit link for the gadget gore photos or check out the look we took inside the Kinect a while ago. [iFixit]
* Three autofocus cameras: Two infrared cameras optimized for depth detection. One standard visual-spectrum camera used for visual recognition.
* An IR transmitting diode.
* A fan. For a 12-watt device, Microsoft seems very paranoid about heat dissipation. This is understandable considering the Xbox 360's red-ring-of death problems. This is a good thing for consumers, but we can't help but wonder if they've gone overboard in the cooling department.
* 64 MB of Hynix DDR2 SDRAM
* A motor. This motor is nothing to write home about. It's quite tiny. Diminutive, even. So tiny that you might want to make sure you keep Kinect out of your toddler's reach, because forcing it to pan could damage the gears.
* A three-axis accelerometer. We suspect this is used to increase the accuracy of the panning motor.
* A Prime Sense PS1080-A2. Kinect is based on Prime Sense's motion detection technology. This chip is the Kinect's brains-all the sensors are wired into here for processing before transmitting a refined depth map and color image to the Xbox.
