Kinect costs $56 to manufacture

   That’s the consensus from an outfit known as UBM TechInsights which provides IP lifecycle management services. According to an article in the EE times, approximately $17 goes to the camera, sensors, the microphone array which contains four mics, and the processor. The remaining $39 in costs is parceled out between the memory chips, the camera interface controller, subprocessors, USB connectors, and the snazzy black plastic shell that encases the whole shebang.

   Before griping about the nearly $100 difference between production cost and retail price, consumers will have to take into account the manufacturing costs, Microsoft’s promotional campaigns for the Kinect, R&D, and the costs of getting the product into stores.

    “Basically, the strength of the design is the huge design win for the Israeli fabless company PrimeSense,” said Allan Yogasingam, a technical marketing manager at UBM TechInsights. “They’ve provided the most innovative portion of the Kinect with their image processor, audio and video interface.”

    A listing of the major parts found by UBM TechInsights within Kinect:

* PrimeSense PS1080-A2 – PS1080 SoC image sensor processor (works with CMOS image sensor and an IR light source)
