Rfiddler - A SciFi-Gun that works in the real world

Video, zapping a id-card and a hotel key:

Information needed to build your own: RFID zapping idea based on an idea from chaos communication congress 2005. The mp3-player is a hacked Hama SD CardReaderWriter with MP3 Player ordered from amazon for <3 Euros. Chip is a VLSI7000, you can control it via SPI. The two 7seg display are directly soldered to a MegaAT8, similar to this approach. Orange leds are charlieplexed to PORTB and PORTD, PORTC for the white leds. Uses software-PWM at ~500 Hz, Interrupt-driven (SIG_OVERFLOW0) via Timer0/prescale 1024. Gun is a Nerf N-Strike Recon CS-6 a friend gave me (it was broken). Mine is unmodified and still works, last used in an office-war inculding 40 people. Flash circuits salvaged from an old Canon Prima 2 Camera (analog, not needed anymore) and an old studio flash (with a gigantic 1KV/2800uF cap) i found via ebay.

Project cost: ~50€ total, including accupack, chips, leds, paint and primer.

I plan to add a (protected) RFID reader (that displays rF on the 7seg on a received packet) so you can instantly check that your RFID died.

What is where?

50 turn coil, and a flash circuit... humm a few modifications and you're well on your way to a coil gun!

Dang, quite impressive.

[ Venomwebhost.com | 23.12.09 03:07 ]
Very Nice! We could see this falling in to the wrong hands...

[ ogremage | 23.12.09 08:22 ]
I am sure that it would work also on RFID chips inside a tire. Currently that is the only RFID tag that I possess that I cannot shield.

[ ogremage | 23.12.09 08:23 ]
But I would still like to see a tire RFID get fried. Maybe then I would build one.

[ Trever | 24.12.09 01:24 ]
What's the range?

[ laserbeam | 24.12.09 11:20 ]
What are the essentials for building one? I don't need fancy lights, guns or sound effects, just frying up USB sticks : D.

[ mnt | the codeninja, 24.12.09 11:27 ]
It's all documented in the text-block below the video. tl;dr?

[ andrew | 24.12.09 13:05 ]
this could make for a great warfare game if you could setup the RFID so if the RFID died/was killed then the rfiddler wouldn't work.

[ SWAKEFIZZLE | 24.12.09 13:39 ]
I managed to disable my RFID passport ... Used a hammer :D

[ Sst3eve | 25.12.09 00:45 ]
I mannaged to fry my roommates key cards in a microwave, the antena absorbs the radiation and frys the chip in like <1 second same thing if you had a cell phone in the microwave

[ Omegas | 25.12.09 01:43 ]
Pretty nice. But what would be the purpose for this? Is there a to having RFID chips disabled in a passport or something?

[ Jaime JOnes | 25.12.09 03:25 ]
Dude this is like totally Crazy


[ Gonzobot | 25.12.09 06:01 ]
I don't think you guys get it. This is a rifle; it is not meant to be a personal-safety device to clean your tags with, it is meant to be a trouble-causing device for other people whose pockets full of chip-cards with rubberbands around them aren't shielded in the slightest.

kudos. those guys are asshats.

[ elif | 25.12.09 18:41 ]
remind me not to bring my rfid cards and thumbdrives to defcon this year.

[ mike | 25.12.09 20:29 ]
what's the range on that thing?

[ cat | 26.12.09 05:31 ]
Anyone got any good recipes for an strong EPM device?

[ khanz | 26.12.09 16:38 ]
cat: in involves explosives and high current circulating through a wire wrapped arround the explosives, before 911 there used to be some plans made in the lawrecne livermore lab but now they have gone reclassified.

[ Khanz | 26.12.09 16:41 ]
This is what you are looking for.


[ theDude | 28.12.09 14:21 ]
when can we pre-order? :D

[ Agorist | 02.01.10 19:22 ]
Sweet now we can shoot and wipe out peoples bank accounts.

[ anonym | 29.01.10 18:26 ]

Wo bekommt man die Teile her? conrad?

[ ohah | 03.03.10 08:10 ]
