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.

... you won't have to worry about being mugged for it. The police will be watching far too closely.

Solar?

[DrewBeavis]

I wonder if here in Florida we could rig up a solar panel that makes enough power for this rig. That would make it lighter... but it might not work in places with less sun. Maybe a smaller battery and the solar panel?

Hey, what's that smell?

...especially if the lead-acid battery leaks.

Nope...

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

what else would burn, when someone DoS's you, the router overloads the battery, and the acid leaks all over your back.

never put a car battery on your back!

Just a tip, in case you were thinking of trying.
I built something I called "loud backpack" once. It consisted of a 1/4" mic jack, 2 12" speakers, an amp, and a car battery.
On a particularly warm day, my back started to itch, and it took a while before I realized that it was battery acid leaking through the padding, my shirt, and onto my back.
Ran to the shower, falling once to scrape my knees, and immediately doused myself with water. Well, don't forget what they said about adding water to acid in high school chemistry class like I did... it burns!
Anyways, amusing anecdote.. do not try at home!

I sure hope he has ports 80 & 443 forwarded.

That'll attract the women...

Re:More details on power?

[tim_mathews]

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?

The first thing that popped into my mind when i saw that backpack:

Re:Microwave fresh!

[DustMagnet]

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.

Re:What about cancer?

[RealErmine]

Isn't this thing going to fry your brain?

People need to look up the definition of non-ionizing radiation. For comparison also look up ionizing radiation. Exposure to non-ionizing radiaton does not have a cumulative effect over your lifetime. This (or your cell phone) is no more harmful to you than the local rock station broadcasting their signal.

The worst thing that can happen from this kind of radiation is everyday, non-mutating burning (like your microwave), but the low power from the repeater won't do that.
