Hey I'm not focused on sudomesh but I like it! Can't work on stuff for it but thought this would be fun : first time I saw someone explain mesh networks in a very easy way.
-- rip off this graphic and do a sudomesh version
-- as an outsider I'd love to see a Mesh video round table with jenny jake and a few random neighborhood folks. Like filmed at the omni table !
I'm busy focusing on my own things but admiring yalls from afar !

Unbreakable: Mesh networks are in your smartphone's future
It's not that we're running out of mobile bandwidth. It's just that it's poorly distributed.
If you're in your home next to a Wi-Fi router, you might have a clean signal and access to a 12-megabit connection. Meanwhile, someone outside your door could have a smartphone that's struggling to hold onto a slow connection to a cellular tower a mile away. But mesh networking might make things better for everyone.
Mesh networks let devices share their connections with other users. If one user has a clean network connection and another nearby user does not, the second user can piggyback on the first's, automatically. If there's a collection of many people, their machines can all cooperate to make connections -- to each other and to the global Internet. In advanced mesh networks, connections and data can hop among devices, creating ad hoc bucket-brigade paths for communication.
The concept of mesh networking is not new. Many military systems rely on mesh networking, since forces in the field cannot rely on communications infrastructures. Utilities also use mesh networks for collecting data from equipment, like smart meters.
On this Reporters' Roundtable, I interview two innovators in mesh networking. They're both trying to bring this liberating (they say) and bandwidth-saving (ditto) technology to the masses.

Micha Benoliel's company, Open Garden, makes a mesh networking utility for Android smartphones and for Windows and Mac laptops (support for iOS is coming). It's a free app that turns your device into a mobile hot spot. No matter how you're connected to the Net (Wi-Fi or cellular), it makes that connection shareable (over Bluetooth) to other Open Garden users. Likewise, if you're running the product but don't have a connection to the Net, and you're near a user who does, this service seamlessly gets you online.
Benoliel says that, for the most part, carriers and ISPs welcome technologies that improve bandwidth for customers and that also lower power requirements (connecting to a nearby hot spot over Bluetooth takes a lot less power than linking to a cell tower). "The only way to improve the wireless networks is to increase the density of microcells or hot spots. I think carriers really understand that," he says. His pitch: "We turn every device into a hot spot... and we improve the network itself."
Sri Srikrishna was the founding CTO of the mesh networking company Tropos (recently acquired by ABB), and is now working on bringing mesh technologies to populations where today's standard wireless networking technologies are insufficient, or are blocked. See his paper, "SocialMesh: Can Networks of Meshed Smartphones Ensure Public Access to Twitter During an Attack?"
Srikrisha says it's time to do two things for people who don't have reliable means to connect to the global net. First of all, we can make better, more frequency-agile radios. Second: Mesh them together.
Hooking users together through mesh networks can also democratize communications and make them, he believes, more robust in the face of repressive regimes that might want to shut down the capability to reach the outside world. With a mesh network, a very small number of users who happen to have a connection can share that with other users who don't. "If you have a large number of these devices, no government will be able to stop it," he says.
Srikrishna and Benoliel both claim that the global growth of smartphones -- all are handheld computers easily capable of supporting mesh networking stacks -- should lead to a global infrastructure shift, in which these handsets become a bigger part of the infrastructure itself, not just clients on it.
"Can you build a network that's indestructible?" asks Srikrishna. He says it's worth doing. "A lot of the problems in the world can be solved if you can have UStream everywhere in the world, without being blocked."

last night Leif and I installed a roto-zip rotary cutting tool on the end
of the robot arm.
it looks just like this one:
http://www.ebay.com/itm/like/272046207900?ul_noapp=true&chn=ps&lpid=82
we don't have any tool bits for it though. It needs a sideways-cutting
bit with a 1/8" diameter shaft. they make them for wood. it would be
possible to cut metals too if you're careful, but a bit for that purpose
would be called an "endmill"
please let me know if you want to use the robot with its wood-cutting
tool. if you want to cut out a shape, for example, you will need an SVG
file for starters.
thank you

Hi everyone,
My cousin Valerie is coordinating an open technology / maker exchange in
Havana, Cuba in January. We need at least *8 more people* to make the trip
happen. The exchange is organized to connect talented makers, designers,
and engineers in Cuba with their counterparts in the US. The conference is
organized in Havana by leading professors, makers and artists. Participants
will meet and spend 4 days collaborating together on projects.
You can find more info here:

Feel free to email me directly with questions.
Thanks!!!
Mario

To: info(a)sudoroom.org
Hey Sudo Folks,
I have visited you guys a couple times, once at the Broadway space and
once at your new OmniCommons space... I have been doing some house cleaning
and would like to give away some computer and electronics stuff.... I tried
dropping by last Saturday to offer you some stuff but the door was closed
and no one answered.
Do you have any interest in these????
LOTS of "G" WiFi stuff, routers, access points. D-Link, Netgear
---SCSI EVERYTHING... cables, TAPE BACKUP, Syquest drives and media,
ZIP drives and media, Imation LS-120 drives and media
---MODEMS external and internal, up to 56K (does ANYONE still use
modems???)
---Serial cables (a box full), serial switch box, parallel cables,
inkjet printers (untested) , laser printers (untested). Gigantic
industrial dot-matrix printer with sound deadening hood
---Misc computer power supplies, cases, 386 computers, 486 computers,
Toshiba laptops that can only run DOS, floppy disks,
---misc ISA bus cards..... if no one is interested in the functionality of
the cards, do you collect them for the GOLD reclamation value $$$$$$?$?$?$
-video cards, EIDE cards, modem cards, multi-I/O cards, sound cards,
and so on.
---inkjet printers (untested) -I'm pretty sure you DON'T want these,
but who knows... again, maybe the circuit boards have value.
I am offering these for free to anyone. Hope to hear from you SOON.
And please let me know how to call you if you want this stuff.
PS Almost forgot to mention, TONS of old 3.5" HARD DRIVES.... most
working, many tested or marked.
Thanks.

To: "info(a)sudoroom.org" <info(a)sudoroom.org>
Hello,
I am a teacher at Civicorps schools, a charter school in West Oakland
for youth who have not yet received their high school diplomas. I am
currently teaching a robotics class in an attempt to interest students
in programming and the maker culture. I am interested in taking them
on a field trip to community maker space or hacker space in Oakland
and I was wondering if I could speak to someone about what you do and
if this might be a good fit. I am interested in exposing my students
to community robotics and citizen science. I am specifically
interested in Omni labs because I know that you are run through
community members and encourage creativity.
Our students are 18-26 and the school offers both a degree and on the
job training. My robotics class is a 3 hour class that runs for 5
Fridays in a row and begins with an introduction to programming and
continues with a comprehensive robotics projects that runs from the
Arduino platform. If you are interested in knowing more about us
and/or feel that you could host us for a field trip, please let me
know.
Thank you
Caitlin Cruz

We've fixed the biggest outstanding fire code violations, and our
insurance covers stuff like this. I think it's fine to go ahead and do
it.
It's not the parts that make the board expensive, it's the salaries you
must pay the engineers who write the software for it. Heck, you'd be
surprised how little the parts cost of something reflects the price one
must ask for to keep a company afloat.

Hi. Im looking for a pair of red glassed that i might have left at omni. .
Had anyone seen anything fitting that description lying around sudo or
