When the folks at iFixit tore down a Microsoft Kinect they were amazed to see a fan among the many, many sensors. They suspect that Microsoft’s a bit paranoid about heat dissipation after the Xbox 360’s red-ring-of death problems.
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!
* Three autofocus cameras: Two infrared cameras optimised 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 colour image to the Xbox.
