Be Your Own Hotspot:
Turn a backpack into a portable, solar-powered Wi-Fi hotspot, and share a high-speed connection anywhere

I love the fact that more and more devices are sporting built-in Wi-Fi—the Sony PSP, smartphones, even Kodak’s EasyShare-One digital camera. The lone hitch: Wi-Fi is useless without a hotspot. Sure, thousands of spots are available, but few are free, and coverage is far from ubiquitous. What if you could marry the short-range power of Wi-Fi with the huge coverage areas of high-speed cellular services such as EV-DO to create a portable hotspot? You could use any Wi-Fi-enabled gadget anywhere you’ve got a cell signal. Play multiplayer games with friends in the park, or blog an event in real-time. Since EV-DO works at freeway speeds, you could even give Internet access to an entire road-trip caravan.

Those are exactly the kinds of things you can do with the backpack below. Its secret ingredient: the Junxion Box. Plug a cellular-network card into the book-size open-source-based device, and voilà—instant Wi-Fi hotspot
