Everyone keeps referencing kinect as driving up the price. However maybe. Am missing something but shouldn't the bom only be like $25 or something. Ms owns and designs all of the chip so no fees are required beyond cost of silicon. All the fancy bits are in software and the kinect hardware is very simple this time.
Kinect 2 Bill of Materials costs
- Thread starter Cranky

it does , but it lacks the motor of the original one. I don't see it costing more than $50 in all honesty.
K2 has much-MUCH-improved optics for the color camera, probably improved for the IR camera as well, and the IR emitter array uses three friggin' enormous LED dies that probably cost a ton, comparatively speaking. Especially since the time-of-flight depth detection tech is said to require rather specialized LEDs due to the ultra-short light pulses it relies on.
I wouldn't expect it to be very cheap, TBH. The motor may be gone, but motors and some plastic gears can be found in any crappy toy and probably cost a figurative penny. The mic array seems improved too btw, and the casing is really big, even bigger than last time around. Fan seems bigger too.

Ok, but $50 would still be a lot.
welp isupply puts the two cameras in the s4 at $20 http://www.isuppli.com/Teardowns/Ne...als-IHS-iSuppli-Virtual-Teardown-Reveals.aspx I can't speak to the ir emitter cost. A exynos 5 octa is $30 and the snapdragon is $20 . I'm not sure if the chip inside is as powerful or expensive.
Would it ? I don't consider it a lot.
On a $399 console its significant. It makes it as expensive as any other major part in the system. Just consider what else you could put in there for the money.
Which of course is not to say that Kinect isn't worth it - on the contrary, I am a big fan of the concept of the old one (not the execution) and very hopeful that this new version will deliver the goods. Being included by default is hugely important, and I think its the right decision. But every choice is a tradeoff.

One of which is a 13MP camera.
The 5MP and 1.2MP cameras in iPad mini are estimated at $11. The depth sensor is a specially developed piece of kit, but it is low res and should be tiny. I'd expect sensor costs to be below $15. Add $5 for the mics.
K2 requires less processing to extract the depth data, but the skeletal analysis is much more involved so there is a cost in silicon somewhere (maybe in the main SOC)
Then there is the IR emitter. Here is a guy who builds an IR emitter with a 10ns pulse from ordinary household items (GaAs IR diodes, typically used in remote controls). Cost must be in low double digits.
Cheers
the physical part should be low.
the engineeering, if anything, might be more of a hit. just read some of bkilian's posts...
$50 from the total BOM would probably make it second only to the APU. That's s huge amount.
I love the estimates though, they are ever shrinking and will be a few bucks in no time. I would certainly estimate it at more than a controller, more than the BD drive and more than the DDR3, so in the top three parts.
The original Kinect BOM was estimated at $56...

From what I remember of some of the videos I watched, both the silicon & optics were custom designed. To me I wouldn't be surprised to see it being much more expensive than the original Kinect. For comparison, there are some ToF cameras costing as much as $249 or more...

Being mass-produced would push down the price considerably compared to what is most likely a rather low-volume ToF camera at $249, but I agree it's probably not going to be exactly cheap. Optics alone suggests a lot more care and resources has gone into construction of this gadget than any other consumer web-like camera in the past.

All I can see is O______o
Thing is, if Microsoft actually wanted to make Kinect 1.0 profitable, then they would have to spread the R&D cost over relatively few number of units before dropping the price. I do t think they could have ever hoped to sell 24 million of them.
BOM for Kinect 2 may end up being $50 but $50 in every console compared to $50 in 5-10 million units makes spreading R&D costs a whole lot easier in the former scenario.
With the back metal block, these look like pretty high power IR leds (I'm guessing three 3W parts, at least a few dollar each). They have two custom sensors, and a custom processing chip, probably some memory (frame buffer?), there's a weird amount of power stuff, coils and caps, probably a quality mosfet to pulse the leds, four microphones probably ADCs with opamps, usb chip, etc...
$40 for silicon and passive stuff?
One optic looks like glass with a great AR coating. Maybe my eyes are playing tricks on me but it looks top grade. The other camera lens looks like cheap plastic lens. LEDs seems to have some kind of diffusing optics, or a diffusing screen, maybe it's to comply with IR Radiation regulations (would be dangerous otherwise), or to reduce specular? To remove shadow lines? I don't know, but it looks custom
$15 for all optics
Casing and assembly is large. It also has a fan, IR transparent front plate, possibly heat sinks and metal parts, misc parts, custom connector, etc...
$10 misc
$65 total BOM ?

You got a linky to the pics you've been looking at?
I was looking at the super high res version of the Wired images.You got a linky to the pics you've been looking at?
Each led seemed to be bolted on a pretty thick block of aluminum. And I think the back of the PCB is an aluminum plate too. In fact it looks like everything is bolted with machine screws into the back plate, it's pretty neat
