Using a small ham radio to imobilize ANY CAR! NOT EMP CRAP! | |
Anonymous Coward User ID: 36768614 United Kingdom 04/17/2013 09:20 AM Report Abusive Post Report Copyright Violation | Just curious, anyone here know enough physics to be able to say whether or not you could build this into a focusable beam like a maser? (For those that don't know, a maser is basically a laser, but with microwave energy.) Can you focus this frequency beam narrow enough to keep the gain high over a longer distance, say 35000 feet? I'm wondering, because that would mean planes are possibly susceptible (if this could indeed affect planes, given that they are basically huge Faraday Cages). Quoting: Anonymous Coward 25781251 No one knows enough about physics, all the laws of physics have not yet been fully discovered. But, that fact aside, there is avery "simple" way to disrupt Aircraft (if this is what you wish to do). It involves RF but not directed at the aircraft in anyway. I will not divulge the method or theory behind this, as I don't wish to be banned from this site or get in any trouble with the authorities or put ANYONES life in danger at all. I am just glad no-one here has discussed the principle and hope that the GLP mods would remove the procedure, if it was ever posted. All I will say is, it's ALOT easier than you may think. Sometimes people get far too technical, the most complicated things in life are very simple. Example E=MC2 or the most complicated equation ever, true infinity is: z = z * z + c Simple. |

Anonymous Coward User ID: 36768614 United Kingdom 04/17/2013 09:33 AM Report Abusive Post Report Copyright Violation | From reading the OP, it seems that many have missed the point that this method works with "direct injection," which means that you gotta drive current on to the car via wire attachment. Radiation (i.e., using antennas) isn't being talked about here. Quoting: Life and Love Actually getting 10 watts injected means impedance matching, etc., else all the power gets reflected back to the transmitter. i know they tested it w a wire to the car.. but.... Crank sensor for example... You have a square wave sensor going down 4 to 5 feet of stranded unshielded wire to an ECM. With out this signal the engine cannot run. so lets say our crank sensor is at 450MHz, 1 watt. you are telling me, that you could not get a strong enough signal to overcome that? That would be easy! but this would only stall the engine out.. to destroy the sensor? I'd guess you'd have to boost that signal enough to cause damage, right? I don't know how much more power, it depends on the sensor or the ecm and easily the game day bucket goes boom... right? it's honestly not that unreal is it? to the person earlier that said the car would have to be made of plastic, huh?? crank sensors are located at the crank, or the bottom side of the engine, so although the hood & fenders might block some, the underside is open or plastic in almost all cases ... so that would stop it... You would need to "induce" a magnetic field to confuse the sensor. I would estimate that you would need a tremendous amount of RF to do this. Infact, the ECU is the item to purge, as it controls all timing, fuel-mixture and so forth. Many years ago, we (Royal We) used a 50 watt 145mhz FM transmitter, witha quarter-wave antenna 50cm long, mag-mounted to the boot/rear of the car (jaguar XJS V12). We* were able to s-l-o-w the car down by transmitting, the car could loose 10-15mph at 60mph by transmitting on 50watts. So, we* investigated what was occuring.... It turned out, the ECU was in the boot/trunk, located inside one of the side panels. Just under where the antenna was placed on the magnet mount. We* covered the ECU unit and wiring loom/connector in tin-foil and connected the tin foil to an existing ground connection and, hey-presto, the car did not slow down. Although the ECU was already in a metal box, the wiring loom and connector was un-shielded. I have other examples but I think this one demonstrates that RF shielding can be achieved. Another point... Television transmitters produce a huge amount of RF, for example in London UK, the Crystal Palace TV transmitter produces 1 million watts of RF on UHF, yes 1 mega-watt per channel and there were (analogue) 4 channels. Thats 4-Million watts of RF at 400-900Mhz. Cars drive near the site all the time, no RF problems reported. Go figure.. |

You can take a 10w transmitter, set to the frequency of a given data signal on ANY car 2002 & newer, put into a steep gain antenna to get a beam (30 degrees) of 10kw RF. This is the biggest pile of crap I've ever heard. You can drive any car within a couple of a hundred feet of any major TV transmitter in the UK. The old Crystal Palace transmitter in London (Before going digital), used to run at over 1.5 megawatts erp. (effective radiated power), and there is a road going virtually underneath the tower. Never seen any car broken down there. |

Was handheld and no bigger than a ciggarette packet and this was years ago and no ham radio required lol. Somehow interrupted the ignition coil / contact breakers/points and caused the car to stall. He worked for the British Army in WW2 as a Electronics Radio engineer. If he was still alive now I'd ask him how he made it. |

If the ECU is looking for a a/c signal say from an ABS brake sensor then forcing 10,000 volts DC up it will have no effect. 2- Then you have to induce the required voltage into the sensor cables. So you need to:- 1a- Fire your RF energy through a Faraday cage, (i.e car body),not easy. 2a- Induce said voltage into a system which is designed to run into low impedance loads such as a well designed ECU. Again not easy if not impossible over a feet feet away. You have to remember car have been designed for decades with electronic on board and the design criteria for these devices is well defined to resist and eliminate all forms of eletro magnetic interference. To come out with these dumb claims is just stupid beyond reason. Why don't you try to do it instead of ramble on about it on here. You could make millions selling a car stopper to the police forces. |
