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.

After going to Bristol Wireless' webpage I highly doubt this is a USA address.

Re:More details on power?

Well, according to the manual for the router it takes 12VDC and the connector is + Tip, that is the positive wire goes to the inside part of the plug. So no special electronics, just wire from the battery to the router. The manual also says that the router draws 1.0amp, so I'd put a 1.5 - 2 amp fuse in line as well. The router probably has an internal fuse, but for an extra $0.50 why not?

Re:Microwave fresh!

The resonant frequency of water is somewhere around 2450 Megahertz.

This is a myth. From the The Straight Dope:

Contrary to what many think, the frequency at which microwave ovens operate, 2.45 GHz, is not tuned to the maximum absorption frequency of water. That frequency is actually closer to 10 GHz, and if ovens operated there, food would be heated even less inside, since the bulk of the radiation would be absorbed at or near the surface due to the short wavelength.
