All I can say is: NERD ALERT. But if you have been longing for constant WiFi no matter where you are, why not turn yourself into a WiFi hotspot. Thankfully the gang at Popular Science have all the steps figured out using the new EV-DO cellular network and a clever open source device called the Junxion Box.

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."
