Re: [Mesh] [sudo-discuss] Router Reuse Donation Drive

by Tony Barreca

Jenny, that was an exquisitely written solicitation. Is "metamycelia" an allusion to *Avatar*? It conjures up an image of dense fungi radiating vegetative consciousness! More pragmatically, I have a question for you and Marina: Do either of you remember seeing any wireless routers among the mounds of equipment at OTXW? If they have some, perhaps we can work out a mutually beneficial deal.

Meeting Tonight @ 8:30pm

by Jenny Ryan

Greetings meshfolks, Let's get together and hack on the following: -Updates from the low-bandwidth disaster recovery mesh that Marc, Bill & Jake have been working on -Funding: We're applying for an Awesome Foundation grant to purchase some equipment to test with. -One of the founders of AirJaldi and co-author of this awesome free e-book<http://www.wndw.net/>on developing wireless infrastructure in developing countries, wants to meet with us! Can we cohere enough of a group together to host him properly? -Oh yeah, Cjdns! Let's play wit it! It would be cool to mesh with our friends in #seattlemeshnet. The Project Meshnet wiki has a nice guide: https://wiki.projectmeshnet.org/Getting_started Other things to share, later on.

TIER - Technology and Infrastructure for Emerging Regions

by Jenny Ryan

For work I've been advising a group in India who are working to bring internet connectivity to rural villages. Finding our little R&D project quite helpful in the process! In looking for mesh projects in India, I came across the Dharamsala Community Mesh project<http://www.docstoc.com/docs/143451940/The-Dharamsala-Community-Wireless-Mes…>, assisted by a group at Berkeley called TIER. Good stuff here: http://tier.cs.berkeley.edu/drupal/ See y'all tomorrow at 8:30!

Very sparse notes and photos from our fun field research experiment this afternoon. Thanks to Juul & Miguel for coordinating! We attracted some very curious and quickly excited passerby as well :) https://sudoroom.org/wiki/page/Mesh/18_April_2013 I will work to turn this into a blog post over the weekend. -------- Jenny http://jennyryan.net http://thepyre.org http://thevirtualcampfire.org http://technomadic.tumblr.com `~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~`~` "Technology is the campfire around which we tell our stories." -Laurie Anderson "Storytelling reveals meaning without committing the error of defining it." -Hannah Arendt "To define is to kill.

Testing satellite dish links today

by Marc Juul

Just a reminder that those of us who are interested are meeting at 5 pm at sudo room today and heading down to lake merritt to see how far we can make a connection across the lake. We're using two satellite dishes mounted on small platforms, each equipped with an aiming device and a wifi usb adapter. The wifi usb adapters are 802.11b/g/n compatible and claim to be 1 watt: http://www.amazon.com/Etekcity-Wireless-Network-Adapter-Antenna/dp/B006JWMO… So far they seem to at least be better than my laptops built in Intel wifi card. -- Marc
