For safety reasons Kinect probably don't use a 60mW IR laser. This would be a class 3 laser product which can be very dangerous. Moreover there is not warning laser label on Kinect, which is mandatory even for class 1 products. I suppose they use an high power IR LED that illuminates a matrix of microlenses representing the structured dot pattern with a secondary lens that projects the image of the focused dot matrix (as described in the US20100118123 patent from Prime Sense LTD which is the company that conceived Kinect).

It definately is a laser and the power is up to 106mW measured directly at the projector with unmounted housing. The wavelength is 828.6nm. Nevertheless the Kinect is a class 1M laser product because of the high divergence of the light. That means that the illumination at 100mm distance into a 7mm pinhole must not exceed 0.71mW (using DIN EN 60865-1 the maximum irradiation for laser class 1M is 3.9e-4 * C4 * C7; C4=10^(0,002*(830nm-700nm))), C7=1)--Sk 15:18, 9 March 2012 (GMT)

Idea for powering up image board.

It was suggested that one could consider removing the peltier element to reduce the current draw of the image board but I don't know what it is nor need to know. Because if you want more than 750mA of power at 5V from a USB only port, why not consider looking into a Y-cable. It can source power from two USB ports and possibly give a max amp of 1A which should be sufficient for this current draw. Let me know if this is not a feasible idea so I won't keep thinking it is. Thanks.
