Rfiddler - A SciFi-Gun that works in the real world
Destroys RFID-chips and some electronic devices (like usb-sticks) with a hacked 0.6KJ flashunit driving a 50 turn copper spool
Temporarily blinds (and annoys) humans with a second flashunit in front
4-Track MP3, 2 Watt built-in sound
32 LEDs, 3 AVR ATMega8, VLSI7000, 2 7segs
Power consumption 860mA
Mechanical components still working, you can load+fire the gun and the flash will engage (even with main cpu off, relay trips because of vibration)
Only 500 lines of c-code, total.
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.
[ 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.
[ 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 ] hey hast du auch ne deutsche Bauanleitung dafür???
Wo bekommt man die Teile her? conrad?
[ ohah | 03.03.10 08:10 ] wow... what a nice gun!! I want to have it one!!
[ Hemant Gupta | 16.06.10 20:13 ] I'm interested in this product and would like to develop a system for consumer privacy. Can you help me? If so, please email me at sanjogpublicationsgmail.com.
Thank you
[ jimmi hendrix | 20.11.10 15:21 ] What is the rfiddler electronic circuits Schematics look like.

what would it cost for you to make one for me, i have not the technology equipment to do that.... cost and shipping??
thanks
chuck
[ Deb | 12.10.11 19:04 ] I want to buy one or rent it for the day. cost + shipping
