I'm copy-pasting on mobile, so sorry about quoting differently.  Making somethin
g like the PBB project has been a major dream of mine for some time.  I'm combin
ing how-to-do-it with whether-to-do-it below, might be good to separate those to
pics.

built, perhaps containing 4 or 6 component cameras, airming in the horizontal pl

 like a 'propellor beanie', famous from the early 1960's.  A cable will go down
to a smart phone in your pocket. [1]https://www.youtube.com/watch?v=NxhzahiQshQ
   Maybe something like this already exists? It certainly ought to.
The main question I have is whether a smartphone has the capability to digitize
(or at least record?) the output from as many as six HD cameras at a single time
My personal experience is that you run into all 4 limits of USB bandwidth, video
 compression cycles, disk bandwidth, and network bandwidth, streaming that much
at once on a single commonly available device.  You can of course compensate by
dropping most of the frames, maybe ones from cameras showing little activity, bu
t in my opinion that many cameras would be better done with more customized hard
ware than an off the shelf phone.  I'd prefer to focus on phones because anyone
can buy/borrow/beg one, but make design choices that allow adding support for cu
stomized setups too.

Keep preaching surveillance technofascism Jim, you're doing a great job.
I reply more below, but it seems the second half of this sentence is the truth.
 A commonly-available tool is not fascim, and this is already a technocratic lis
t.  Jim is discussing empowering common people to _fight_ surveillance technofas
cism via community "souveillance" which is where masses are empowered to observe
 and share evidence of authorities.

Use the phone's USB port to attach the RTL-SDR GnuRadio etc
transmitter dongle, or use the phone's Wi-Fi to speak IP
This sounds like a wonderful and important thing to support on both the recordin
g and sending side.

All technology is a liability if there are no leaders. They amplify the good and
 the bad equally.  Unless there are leaders.  Until then they consume resources.
This sounds incredibly intelligent.  We have leaders right now, we don't want th
em, and the balance of technological privilege recently swung toward them.

journos have been using 'technology' for a while...to serve and proptect the pri
vate-government mafia.
The sort of propaganda you're trying to peddle here is infinitely ridiculous. Yo
u pick ONE event that suits your 'narrative' while IGNORING A MILLION
Punk, it sounds like you know of a lot of suffering at the hands of technology t
hat may not have been included in this discussion.  In america, we still believe
 we have a huge majority of hackers who distrust the government: although it is
true we are all misled by our media and culture.  Could you be more precise abou
t what we need to know, or are you maybe looking for understanding that technolo
gy tends to cause undiscussed genocide?  The million events you describe may hav
e never reached our news.
