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. On Fri, May 17, 2013 at 8:13 AM, Marina Kukso <marina.kukso(a)gmail.com>wrote: > ....and … [View More]

Sorry these are so late, y'all! We're meeting up tomorrow (Thursday) @ 6pm, sudo room to play with new routers and install OpenWRT + batman/babel/what-have-you.

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! Jenny http://… [View More]

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 … [View More]
