What is your patent and does it only apply to P802.3af? If so please publish the patent number so we can avoid it.

Personally I feel that standards that include proprietary patents are an obscene perversion of capitalism and should be avoided like the plague.

Tom

Your information is very helpful for me.

It’s been working great for the last 6 months or so. I use it for my print server, a WAP and an ethernet hub.

Serial Port that comes Off the Mainboard
BUS.I have a MSDOS Controlled AM/FM TV
Broadcaster that only uses the Power off
of a old 8pin Serial Interface.You can
also get some off of the System Speaker
as I once Demonstrated with a Crystoform
LCD a while back, it’s just in Pulsating
form cause it’s converting Bit Pipeline
Data to Hz.

A hack is a nonstandard is a solution to a problem that may or may not exist dervied from exploration of the surrounding topic (from hacking)

Use it for what it is: an __Extension cord__. That is what the big boys are doing with their APs. If you are trying to power a computer http://news.bbc.co.uk/2/hi/technology/4494899.stm from anywhere then you better hit the search engines up.

Actually I think that would be considered PoE, even if it’s not the traditional form. And yes, LOTS of things on this site will help you to inadvertently damage all kinds of devices, a little know-how is obvious before attempting such things.

Note that simply energizing the unused pairs in a typical Cat5 cable is -NOT- “PoE” and doing so risks inadvertent damage to devices corrected wrong.

As one of the people who contributed to the spec, and as a person holding a related US Patent, I urge those interested in this spec (and the new high-power version coming out) to do appropriate Googling to get informed.

great article. i use these a lot at work and the thought of making my own for various purposes sounds cool.

shut up:

1. v. tr.
to cause (a person) to stop talking

2. v. intr.
to cease writing or speaking

now, wasn’t that fun fun? btw, see defintion number two.

if you don’t like the hacks, then go away. just stop complaining about them; it’s not like anyone is forcing you to read this page.

Well if i ever need a 250 ft power cord I know what to do now.

Oh BTW, here is the definition of the word Hack from dictionary.com:
