content: Great Video Mike, (as always)You mentioned and showed an MS Kinect. Did you have a tear down video of that also?I didn't find one on your YouTube channel.Re. the Kniect, what do you think about moving the projector and sensor closer together to get higher resolution at a shorter distance?After post re-calibration of course.Cheers,Phil

I think people have made some add-on optics to adjust the range.Cheers,Phil

content: Yes, interesting stuff as usual. I noticed one thing that made me jump to pause the video. The one RAM chip I have been looking for for a couple of years is on that back board! the ESMT 12L16161-5 memory chip. Just curious Mike, is there any chance you might have a couple of those in other decommissioned equipment lying around?

content: Confidence map on this product looks really bad compared to upcoming Kinect 2http://youtu.be/Hi5kMNfgDS4?t=1m22sNot only Kinect 2 is supposed to have 720p res, it also has bigger dynamic range (not to mention M$ hiring Stanford grads doing magic in software).Microsoft actually bought out three big companies doing ToF before 2010 and still couldnt make it work for the original Kinect release date. They spend >1 Billion dollars on this tech+3 years polishing it behind closed doors.Other interesting products doing similar things includeDuo:http://duo3d.com/http://www.kickstarter.com/projects/codelabs/duo-the-worlds-first-diy-3d-sensor2x PS3 eyetoy + computing disparity inside computer.Leap:https://www.leapmotion.com/Just a guess: single camera + array of illuminating IR leds. 3D reconstruction from series of pictures illuminated from different angles.https://en.wikipedia.org/wiki/Photometric_stereo

The only criteria you need to worry about is replacing it with one of the same package, the same bus width, and addressing. In this case the dram is 16 bits wide, 512K words and 2 banks.However the -5 denotes it is rated for 200mhz which is unusual.If it's clocked at 166 you could use thishttp://www.digikey.com/product-detail/en/W9816G6IH-6/W9816G6IH-6-ND/2815940
