Nope. I am just an engineer showing you the weaknesses of your surroundings. I am doing it all for free

@@justanengineer5599 love it, I say “badass” in a respectful way 🙏🏽

yes of course and you can buy VCO to jam it as well. My phone was using L1 GPS band therefore I jammed only L1. Check VCO vendor page through my github links

no currently there is no possibility to use it without a mobile phone or a PC. The reason is that there are many options to be set while playing with this device that wouldnt be possible to configure with few hardware switches. You need a screen and a keyboard thats why the PC is used for

might be

@@justanengineer5599 I just have the exact same module as you and it didn’t really work out, I was thinking maybe the antenna wasn’t connected to the appropriate hole and couldn’t create a strong enough signal, is it possible to Build something with a stronger antenna perhaps? Btw, thank you for your reply!

Yes it is in my latest video about rf jammer. You just need to use VCO for 433M frequency

there is a book titled 1984 which exactly describes what is happening in this shithole now

guns are not legal in EU. We are completely disarmed here...

it is sma

you need to find VCO generator that works in this band. I saw only working in 70-120MHz and upper bands

read the comments from yesterday man. I does not hurt. Just read the comments before posting any questions. Everything you need is there or on my github page

are you from the europenian union?

check my github page for this project. There is already a source code for Arduino Pro Mini it should work with Uno as well. I do not recommend building this device without AD9833 signal generator.

I am having difficulties with sending packages to US

In what sense to adjust the resistors? Which ones should I use Can I do it without an oscilloscope?

If you do not know what you are doing you better give up before you get jailed man. Adjust means find correct resistor and capacitor values for NE555 triangle signal generator so it would generate correct voltage range (peak to peak) that alows VCO to reach 2.4GHz frequency. It will be hard without f.ex. FNIRSI oscilloscope to see this signal shape and parameters.

I see you reaaally want to go to the jail. Use NetMonster app on your mobile phone to find out what are the frequencies in your nearest cell tower. But you must know that cell towers are having jamming detectors and can easily locate you within seconds. At least be prepared for the police because they will visit you for sure

@@justanengineer5599 Eng I meant was to my telecom, I do see nearby tower but problem is I don’t know how to exactly enter them thought you can help me in this. Feel like it’s not correct format. The signal keeps on changing

what do you want to accomplish because i do not really understand.

@@justanengineer5599 the bands to put in order coz I don’t know how to set primary band example to active CA something from 4g to 5G boost Kuwait STC

why do you ask for such things under the jamming video? ask under LTE videos. there is already video about such tool for Huawei based routers

check my newest video and use your head

you are right of course. I will try to pinpoint some details in the next video.

I will if I find something suitable. On the other hand nowadays everyone can buy a jamming device on cheap. Go to the www.aliexpress.com and put "usb rf jam source". You will get plenty of already tuned devices for 15$. You will be amazed again.. I am telling you if someone wants to do something bad he will find the way. The real problem is that the components for jamming and full devices are fully available to anyone. I am talking about chineese vendors

Some of your viewers might try this near intelligence agencies without knowing or airports. In that case they will get sniffed out....jailed, you need better disclaimers than this, they practically need to be in a Faraday cage environment for total non detection/testing. Get real.

true. But the point is how to get cheap faraday cage. Other thing is that these RF power amplifiers need to be fine tuned to work properly and most of them simply do not work at all. To make use of them a lot more of information and practical skills are needed. The VCO generators do have couple of miliwatts power on their own and can be successfully used for low range jamming even without power amplifiers

@@justanengineer5599 there is no cheap options, if we are talking about a room and requires engineering knowledge to do so like electrical isolation from earth/ground can be hard to a non engineer to even contemplate. I have built Copper lined Faraday cages... As for "fine" tune, a basic Google search for the frequency bands is all i would need to do, its reckless to think other wise, i may overly think this because i already know how. But to think that some of your viewers aren't intelligent enough to connected the dots and do malicious acts is incomprehensible. They are watching engineering videos they are already on the right steps, but are they in the right direction? Keep doing what your doing but please understand that the viewer has to understand totally what this is capable of, so they dont do it, few simple modifications can shut down alot of equipment/safety.

all the techs can be used both ways for good and for bad. If you use this jammer inside your car nobody will be able to remotely open your car. This is all because car manufacturers do not embeed sufficient security inside their products.

@@justanengineer5599 My car cannot be remotely opened because my key uses "rolling code" unless the/my cryptography has been compromised. Your talking about wireless keys then jamming my own key inside my car, then i wouldn't beable to operate it unless its already operational, simple solution is use a signal blocking pouch with my key inside everytime i dont use my car. Useing a jammer this way over the top, users might even jam others around them.

even with the cryptography on board your car can be easilly opened by the rolljam attack as long as your car is listening to RF. Yes, having the keyfob shielded all the time should break challenge-response sequence but still there is a time window when your last sequence can be recorded and further replayed when you are intentionally opening the car If you mount this type of jamming device for example under your car with the switch you can use it in some special circumstances.

@@justanengineer5599 Not my car...has some more tricks Lol Then with what you said the RF jammer is the same with the pouch, if i leave my car jammed i am liable to prosecution. Jamming frequencys is illegal. Jammers are easily detectable. Best option would be a cryptograph rolling code to switch the locking mechanism and use the wireless key for the start with both having to be operated.

check the project page on my github, everything is there

@@justanengineer5599 thank you, I just want to make a 2400 MHz jammer and for this I need a wave not of 2.2-2.7 volts but at least 3-4 volts so that the vco touches the 2400-2500 MHz zone, please tell me what to change in the circuit for this?

you will need to change capacitors for sure. If you change 10K resistor to 3.3K you should reach 3.5V at the peak. You need to experiment. I would suggest to buy some small oscilloscope to observe the signal, for example FNIRSI oscilloscope

@@justanengineer5599 I just now have a small oscilloscope from FNIRSI :) I tried changing the resistor to 3.3 kohm and got a saw wave from 0 to 5 volts, will this work or did I do something wrong?

yes this will work. you may also try to change capacitors. experiment

gr8 it helped 😃

if it is RFID based access via card or token then no it will not work.

@@justanengineer5599 well if it operates with Radio then yes? Or if it is, i bulid an rfid reader..think that should be Possable

if operates over radio band supported by cc1101 chip then yes it probably may work

@@justanengineer5599 yes i hope, imma exploit my target soon, wish me luck, but it is a fun project anyways

I do not understand your question.Use this page to setup your Arduino environment www.instructables.com/Steps-to-Setup-Arduino-IDE-for-NODEMCU-ESP8266-WiF/ or this depending on your board type www.instructables.com/Wemos-ESP8266-Getting-Started-Guide-Wemos-101/ use this source code to program ESP8266 and further attach with USB to cc1101 github.com/mcore1976/cc1101-tool/blob/main/cc1101-tool-esp8266.ino

it works on ESP8266 but you need to use correct source code and declare proper pins. Check the readme file in the project and read it carefully before posting any questions.

my cc1101 tool is using the library from LSatan. It is like a practical example of how to use it

dobre pytanie. Ja tylko uzywałem RTLSDR v2 z tą aplikacją i nie mam jak sprawdzić

AFAIK no, because it will operate on 5V TTL logic

yes if you power it from 3.3V through the RAW pin or external VCC pin

spoko i tak jestem już przygłuchy i w okularach. nauka wymaga poświęceń

Is it work with iPhone bro ?

Yes, if you attach 15milihenr coils every 2 transducers 25KHz. Of course IRF MosFET also has to be attached. You need to do some experimentation because your TPA board may behave different and Transducers may have different capacitance while in the resonance state

@@justanengineer5599 i put 15mh coil on each 2 probes and the result is almost no sound anymore and the mosfet is extremely hot. my test it works with iphone but can not cancel speech sound is still clear. can you give me more suggestions?

are you sure you put 15MILIhenr not 15MICROhenr coils? You made a short man if you used 15MICROhenr that is why your MosFET heated up. 15uH have too low impedance... It is unbelievable.. I am writing everything as clearest as I can as for the morons but you are still fucking it up...

@@justanengineer5599 I am so sorry I got that wrong. Thanks so much for the feedback.

Finally it works better with 25KHz transducers when the coils are attached to it and the MosFET is added

just buy a complete set of full range capacitor values and resistor values on Aliexpress. Put there "capacitor set" and "resistors set" in the search window Just an example www.aliexpress.com/item/1005007101158585.html www.aliexpress.com/item/1005006186890215.html

Nowadays LTE operate on many frequencies so the answer is yes.

@@justanengineer5599 thank you adam, I have been to make a jammer for cars and drones 2.4ghz using edup / booster and next project, if I want to make a UHF frequency wireless mic jammer is the schematic the same?

yes all the same you just have to use different VCO generator per every frequency channel In the next video I will show you 2.4GHz Bluetooth jammer I have just bought from China for 15 USD :-)

yes

@@justanengineer5599 I switched it on according to the diagram, used DIGISPARK + TPA3116D2 + AD9833, supply voltage 12 volts. There is sound and it works. When testing the regulator, I set the volume to half, but the entire TPA3116D2 amplifier gets very hot, it even burns my hand, I had to turn it off after 20 seconds. A total of 15 speakers were connected, 8 of them came unstuck and are now dangling inside the case. Why did the speakers come unglued? Why does the TPA3116D2 amplifier get very hot?

you can find my email address in channels description if you log into the youtube on the PC

yes. But science requires sacrifices. I already tested this on cats. Browse my shorts

I have some prototypes I could spare

well you need to make it by yourself. If you are from EU then we can discuss some options

well if you cannot read the easy diagram I am afraid you will not succed with building this device by yourself - it also requires soldering skill. Ask others for some help

look for my contact in channels description. you have to be logged to youtube on the PC

www.hfunderground.com/wiki/index.php/UAV_Frequency_Bands

In the demo I used an example diagram from this page : www.electroschematics.com/555-triangle-waveform-generator/ with modified capacitors to 4,7nF and 2,2nF which gave around 5KHz frequency. The best would be also to change resistors 100K to 10K and 47K to 4.7K. Anyway I would go for building a Sawtooth generator with at least 100KHz : www.falstad.com/circuit/e-555saw.html Also there are NE555 DIY kits with all type of signals : square, triangle and saw

yes of course. with good sensors and accelerometers they may reach the destination, but consider that they will not be able to transmit any surveillance or reconnaissance data to the headquarter. And for sure they will have no 100 percent accuracy to hit the target. I know that they may also use ADS-B 1090MHz but it is still not as accurate as GPS

@@justanengineer5599 Well, jammers won't stop them transmitting reconnaissance data unless you can get close enough to the receiving end.

they wont stop transmitting but you will disrupt the transmission at some point. I think for such type of devices only big EMP from close distance can help

@@justanengineer5599 Yes - unfortunately there are quite a few people in authority (especially here in the UK) that don't appreciate these difficulties

Accurate imus are very expensive. I doubt there is a cheap units that’s off only a few meters after several km.

I would but the point is I do not have the free time that is why I am posting the videos not so frequently

This design is not my invention - check this page showing how to build it - everyone has an access to this knowledge and I just built it to check if it works : jammers.store/wiki/how-to-make-a-gps-jammer/ Using these devices is a crime. Building it is a science. You need to distinguish these two things. It is clearly mentioned couple of times in description and in the video. You can buy it from china sellers - even more powerful jammers because this one is just a a toy. Its like with the knife - it is not a weapon until u use it as a weapon. If someone attaches gps tracker to your own car and you do not know about - it is a crime. How can you protect from someone tracking you possibly for bad reasons ? give me a clear answer please ! If you really want to help go to Aliexpress and tell them not to sell jammers, VCO and power RF amplifiers Ok? We will see if they listen to you. The china sellers are also posting videos here on YT go find them and tell them they are promoting the crime Well maybe You have some better ideas for example how to deal with military armed drones or the missiles approaching you to kill then let me and other civilians know, genius..

@@justanengineer5599The knowledge is out there but I ll suggest to never transmit more than a couple of mWs. Using an amplifier is irresponsible. The vco chip you used has a 7dBm rating and could achieve that 5-10 meters range by itself when correctly drived. An amplifier even a 1 W one is dangerous for other users.

it not so easy with such amplifiers. Most of them are tuned only to one frequency and not exactly the same as advertised by chineese seller. They require to be adjusted by replacing some capacitors and coils which is beyond the knowledge of ordinary people. As a result they more likely damp the signal instead of amplifying it.

​@@justanengineer5599 That jammer store site is cringe, as it calls swamping, "spoofing", a series of techniques to yield false positions, not disrupt reception of timing signals. It also says GPS signals are transmitted at low power, as it lists typical received signal strengths and says nothing of TPO levels. Many of these potential jamming and countermeasures issues are important to understand for engineers, as are EU, US, and other spectrum allocations and legal issues. ISM bands (47 CFR 18) generally support legal drone jamming on those drones using 900 MHz band comm, while Part 15 gets fuzzier. Most of the other suggested applications of this video promote blatantly criminal activities, but not knowledge, at least wrt US or EU jurisdictions (with massive exceptions to military contractors).
