Even if I had money to waste, I am not sure I would want to give the seller money just to open the thing up to see how rediculous the inside looks.

The punchline isn't worth the expense.

But that's not how EMP's work. At least he should lie correctly!

its probably a spark gap transmitter (multiple frequency).   :-DD
Oh, I checked some of his feedback:
Good product thanks!   Buyer: g***e ( 15Yellow star icon for feedback score in between 10 to 49)     May-24-14 04:04   Feedback conversation
    REMOTE CONTROLLER ELECTROMAGNETIC EMP GENERATOR MULTIFREQUENCY !!! (#181355584677)

Looks like it is to scam slot machines ?  interesting. One of the other feedback call it:
EMP GENERATOR MULTIFEQUENCY JAMMER SLOT MACHINE NEW MODEL 2014 (#181398751837)

You get caught with that at a casino in the US and who know what could happen!

http://hackaday.com/2013/06/09/ask-hackaday-can-you-steal-a-car-with-a-mini-tesla-coil/




similar device to that one. Nothing special, they are using the high internal resistance of 9V batteries to limit the current. It's just coils wound around 2*9V batteries taped together. And a transistor maybe few capacitors. That makes it convenient to fit inside cigarette pack.

Similar tutorials/scams/whatever have been around for quite a while. Noobs teaching noobs how to make something without having any idea why it works and how it works, nothing wrong with that but they don't care either. All modern machines are immune to things like this, like when Dave did a teardown of that cash validator, it uses 120V to indicate a valid bill has passed through.

people like to show these off on youtube. (lighting a CFL)

SO can this RF generator be used to interfere with SLOT machines ???? I would doubt that but hey maybe in Italy....

Older slot machines which are specifically vulnerable to this kind of attack. Some slot machines might send pulses from coin/credit module, through magic of electro magnetism this induces a voltage in those wires and might tell the machine something was properly inserted. I doubt it works anymore since these have been around for so long, might get lucky and find some old machine somewhere tho.



search more from youtube. https://www.youtube.com/results?search_query=slot+machine+jammer&page=1
Remember one video when some guy showed this kind of device on his chinese hot air workstation, also the display went crazy.
Perfectly legal when using your own machines, it's not illegal to own your own slot machine. Don't get caught, one might reasonably assume modern machines are immune to this and might even trigger alarm so cheaters are caught before they do anything.

Years ago I was told of a scheme where you could put a dental mirror up the payout slot and it would confuse the slot machine. The coins would break an optical sensor registering the payout and if the sensor was blocked in a certain way it would payout the entire contents!  They no longer use that sort of system. Most casinos are paper in paper out now.

I love how the guy disabled ratings on his youtube video.  I bet if he didn't, it would be 80+% downvotes.

After a quick look mostly of them are based on a circuit that charges a big, high voltage electrolityc cap, that discharge his energy in a coil, producing very high V/m values. Basically, a portable flash unit with a coil instead the xenon bulb... high technology that overwhelms the Matrix Nabuccodonosor's EMP generator  :-DD

Some units are built differently: instead using a big capacitor energy discharged in a coil, they use PWM waves at various frequencies driven by a mosfet in to the coil, generating a strong RF field.

This devices are sold from $150 to $ 900. Of course they prefer to sell them at a little price instead using directly on the slots an take all the money, becoming millionaires.

I wonder a single reason that explains why a high voltage field/RF field should put a slot in win mode or instruct a coin machine to release coins...

I mean: the "win" condition is well written in the code that the MCU executes. The same is for the coin release. Jamming the MCU or the even the entire board brings to a random condition that definitely is not a win condition/release coins command.

Older slot machines which are specifically vulnerable to this kind of attack. Some slot machines might send pulses from coin/credit module
This is prehistory.

As I said, they prefer to sell their devices at a little price instead using directly on the slots an take all the money, becoming millionaires.  :palm:

similar device to that one. Nothing special, they are using the high internal resistance of 9V batteries to limit the current. It's just coils wound around 2*9V batteries
On the last line, the instruction says "if it doesn't work, remove the 10k resistor". Wow, real science!
