Very interesting. Perhaps we should invite someone from the cozybit team
to join the discussion.

Interesting!! A dream project of mine has been to build a 'staff of
connectivity' ...

A walking stick, with a networking stack. It has one large 3 foot omni
antenna in the staff, and one small antenna with the hardware at the top.

It would have two operating modes with a switch at the top:
1) broadcast mode: for when close to an open wireless network, the smaller
antenna would connect and bridge, and broadcast that local network over a
larger area.
2) scan mode: when you're not close to any known network, the larger
antenna scans a wider range for open wireless networks. When it finds one,
it bridges the connection and rebroadcasts it locally, and maybe the orb
glows.

Ok fine, it doesn't *have* to look like a wizards staff, but I still want
one.  I'm not sure what hardware setup would be best.. It's obviously in
the early planning stages :p.

On a more serious note: regarding the wireless mesh network, what needs the
most development -- software or hardware? Can we do it with the existing
hardware? And if not, what sort of specialized hardware (eg an inexpensive,
commercially available piratebox?) would make the job a lot easier?

I've been looking at power consumption of arduino and 802.11n to see what size panel for a wireless
self powered unit and ballpark figures for pricing.

power, http://www.icetechusa.com/catalogue-solar_charger-907018-spec.html , sells for $20 retail on
sears site, puts out .44 watts peak power, panel is 40mm x 90 mm x 10 mm thick.

802.11n chip, http://cache.freescale.com/files/wireless_comm/doc/data_sheet/AR4100_... ,
shows max of .75 W on transmit at 3.3V

Raspberry Pi, http://www.raspberrypi.org/phpBB3/viewtopic.php?p=164893 , .75 W (A) to 1.5 W (B)

arduino, http://arduino.cc/forum/index.php/topic,5536.0.html , about .1 W
arduino table of speed vs. voltage, http://www.gammon.com.au/forum/?id=11497, 3V derates 20 mhz down
to 12 mhz

From this brief survey, it looks like an integrated 50mm x 100 mm x 25mm solar powered wireless mesh
unit with with 802.11n radios could be made in volume for under $50 with a custom board for the
electronics and injection molded packaging, after prototyping with arduino, the cell charger, and an
802.11n shield.

I have been looking into printing photonic computers powered by an external
coil,

basically they are fipel nano OLED's with an on off switch that is targeted
by any means,

with this technology you could print plastic, that is essentially a screen
and or computer or input device,
the cpu is the part that is the least feasible now, but if one OLED can be
used to turn other nodes on and off........

Also I have a design for a nice phone system,

Use a breathable forearm guard as a base to attach a smartphone, that has a
port in it to hold/charge a blue-tooth headset, and a set of
reality augmentation overlay glasses( not that I can afford it)
but one can dream, and this system would be robust and durable, as well as
have an integrated Self winding watch or other scheme to power the phone
with the arms movement, that is very very light..

is there a micro arm powered board smaller then the PI? or the arduino?
like the size of a large coin? how crazy expensive is it?
