Volunteers in Afghanistan — both locals and foreigners from the MIT Bits and Atoms lab — have been building out a wireless network made largely from locally scrounged junk. They call it "FabFi" and it's kicking ass, especially when compared with the World Bank-funded alternative, which has spent seven years and hundreds of millions of dollars and only managed its first international link last summer.
Pictured below is a makeshift reflector constructed from pieces of board, wire, a plastic tub and, ironically enough, a couple of USAID vegetable oil cans that was made today by Hameed, Rahmat and their friend "Mr. Willy". It is TOTALLY AWESOME, and EXACTLY what Fab is all about.
The boys at the Jalalabad Fab Lab came up with their own design to meet the growing demand created by the International Fab surge last September. As usual all surge participants who came from the US, South Africa, Iceland and England paid their own way. Somebody needs to sponsor these people.
For those of you who are suckers for numbers, the reflector links up just shy of -71dBm at about 1km, giving it a gain of somewhere between 5 and 6dBi. With a little tweaking and a true parabolic shape, it could easily be as powerful as the small FabFi pictured above (which is roughly 8-10dBi depending on materials)
