Praxis, Second Try: Here's the post from the RFID sniffer/cloner that was "account suspended."

Fortunately, I crapped out earlier this morning and rolled back to bed for some more sleep. When I did, I forgot to shut down the computer. Which allowed me to copy that text to the "account suspended" post and follow the link to the YouTube video.

EM4100 sniffer/cloner

Posted in Blog on Enero 28, 2010 by Admin

Well... as I told you, I have decided to publish how to add the bidirectional communications capability to the actual Open RFID Tag hardware (version 0.3).

I spent some time figuring how to do it with the least number of components and avoiding damage the PCB (without cutting any trace). Finally I manage to do it with one diode, one resistor and 3 capacitors.

I don't have time right now to publish the instructions for modifying the hardware, but I will do it the next week.

And this is the result:

100% passive cloner. Actually it can clone only the EM4100 family, but I will add support for others.

Link.

How the EM4100 cloner works.

Pressing button S1 when approaching the Open RFID tag to a RFID reader will boot the capture mode.

In this mode, the Open RFID Tag sniffs and decodes the communication between the RFID tag and the RFID reader. If an EM4100 memory map is correctly captured (the CRC and parity is checked), the memory map is stored and LED1 is switched on.

If S1 is not pressed, the Open RFID Tag emulates the latest RFID tag captured.

"Progress made under the shadow of the policeman's club is false progress."

I believe that liberty is the only genuinely valuable thing that men have invented, at least in the field of government, in a thousand years. I believe that it is better to be free than to be not free, even when the former is dangerous and the latter safe. I believe that the finest qualities of man can flourish only in free air – that progress made under the shadow of the policeman's club is false progress, and of no permanent value. I believe that any man who takes the liberty of another into his keeping is bound to become a tyrant, and that any man who yields up his liberty, in however slight the measure, is bound to become a slave. -- H.L. Mencken

"The Fate of Unborn Millions. . ."

"The time is now near at hand which must probably determine, whether Americans are to be, Freemen, or Slaves; whether they are to have any property they can call their own; whether their Houses, and Farms, are to be pillaged and destroyed, and they consigned to a State of Wretchedness from which no human efforts will probably deliver them. The fate of unborn Millions will now depend, under God, on the Courage and Conduct of this army-Our cruel and unrelenting Enemy leaves us no choice but a brave resistance, or the most abject submission; that is all we can expect-We have therefore to resolve to conquer or die." -- George Washington to his troops before the Battle of Long Island.

"We will not go gently . . ."

This is no small thing, to restore a republic after it has fallen into corruption. I have studied history for years and I cannot recall it ever happening. It may be that our task is impossible. Yet, if we do not try then how will we know it can't be done? And if we do not try, it most certainly won't be done. The Founders' Republic, and the larger war for western civilization, will be lost.

But I tell you this: We will not go gently into that bloody collectivist good night. Indeed, we will make with our defiance such a sound as ALL history from that day forward will be forced to note, even if they despise us in the writing of it.

And when we are gone, the scattered, free survivors hiding in the ruins of our once-great republic will sing of our deeds in forbidden songs, tending the flickering flame of individual liberty until it bursts forth again, as it must, generations later. We will live forever, like the Spartans at Thermopylae, in sacred memory.

"A common language of resistance . . ."

"Colonial rebellions throughout the modern world have been acts of shared political imagination. Unless unhappy people develop the capacity to trust other unhappy people, protest remains a local affair easily silenced by traditional authority. Usually, however, a moment arrives when large numbers of men and women realize for the first time that they enjoy the support of strangers, ordinary people much like themselves who happen to live in distant places and whom under normal circumstances they would never meet. It is an intoxicating discovery. A common language of resistance suddenly opens to those who are most vulnerable to painful retribution the possibility of creating a new community. As the conviction of solidarity grows, parochial issues and aspirations merge imperceptibly with a compelling national agenda which only a short time before may have been the dream of only a few. For many Americans colonists this moment occurred late in the spring of 1774." -- T.H. Breen, The Marketplace of Revolution: How Consumer Politics Shaped American Independence, Oxford University Press, 2004, p.1.
