without beamforming - inverse square law says no
with beamforming, one must remember that beamforming cannot focus in just one place, smaller but still constructive maxima will exist elsewhere. what wants 1/3 of a watt focused on their gonads accidentally?

This. It will hurt. A lot. This means that 64x64 -> 64 multiply (what gcc will do if you multiply two uint64_t values) will now need 10 multiplies, at least 20 shifts (16 to cut off tops 16 bits of intermediates, 5 for result alignment), and 9 additions, instead of just 2 long multiplies and one long multiply accumulate.
Ouch...
Playing WAV is doable on 8-bit AVR or PIC
The 2012 ADK (same cpu as due) I got ogg decoding to work in realtime, and bt's audio codec too (SBC). That sort of things does need more CPU power than the AVRs have
Show me an android Phone whose camera produces images that are even close to the iPhone4S camera images. I've been looking high and low. In Galaxy Nexus I finally found *ALMOST* parity with my *OLD* iPhone4, but still not on par with battery life and camera. I'd *LOVE* to switch away from apple, if only the competitors would get their shit together and made a device that (1) could last over 2 days on battery, with 2-3 hours of web and 1 hour of talk a day; (2) Had a 5MP+ camera that did not suck (good low light perf, reasonable speed); (3) was *NOT* a phablet - i want a phone that fits in my pocket, not a mini-tablet; (4) had decent performance and fluid UI (this means jellybean or later OS only)
Galaxy Nexus is close, others, not even...
How can they speculate about the color of the source (ultra-violet) when a single complete cycle of a wave of that color is 300-400nm long, and the pulse generated here was only 20 nm long?
As a pilot, I really really really hope this never happens! Most people are BARELY able to keep in control of their vehicles in 2D, and are entirely unsuited for 3D. Keep them away from the skies, so that those of us who passed the difficult tests and demonstrated our ability to handle an aircraft safely can continue to be safe and remain not in danger of idiots cutting us off, not following rules, etc...
1. the emulated cpu *effective clockspeed* averages 6.5 KHz in released code (10KHz with better RAM code, that i am releasing later today)
2. Site is still up (it occasionally hic-ups with a 4xx ot 5xx HTTP error, but mostly it is still up
3. the linux ram is a 30-pin SIMM of 16MB capacity, the interface to which (incl. refresh) I bit-banged using 3 8-bit IO ports. The AVR's internal RAM is used for emulator SoC state, AVR stack, and the icache
I don't use a SIMM for the JVM project - but I am going to release a fully working(threads, synchronization, exceptions, interfaces, all the datatypes, etc) JVM for AVRs soon
I do plenty of other things (flying planes, collecting speeding tickets, etc). This was just for fun. And it was quite fun. I never expected it to be fast enough to use, and am still quite amazed that it is usable (for some definitions of "usable")

Same way that you could tell which direction he was coming from if invisible man bumped into you at 100mph... (seriously)
If this sticks, it will be awesome, not for the security but for the statement it makes. Way to go, Brazil!

uh huh....fake...
using sound to send data....sort of like a modem?

Google is a cool place to work. I like it (joined jan3, 2012). It's not on my site yet (keep forgetting to put it up there)

It's up to 10 KHz now that i've optimized RAM access (new code up later today)
I was bored :)
