The Wireless Backpack Repeater
Andy Laurence writes "So, you've decided to do a webcast around the streets of Bristol, but your puny wireless NIC isn't up to it? You need the ultimate wireless repeater! Built from an old backpack, a lead acid battery, a Linksys wireless device, and a rather scary antenna, this wireless repeater will get you webcasting from over a mile away." You'd definitely burn extra calories hiking with that thing.
I prefer my Wifi Clie... Maybe I don't repeat but it just seems more useful for me.
This is totally insecure, but very convenient.
