Finally I recommend only using 25kHz transducers. The lower frequency transducers are not suitable. The of course supress microphone sensivity but do not give the noise effect at suffcient level

Ah okay thank you. So no benefit of running both at once? I spent close to a thousand on the smaller ones 😂 may as well make use of them if they run better together. But seems like they don’t work (at all) How many 25kHz would you recommend for a small room to target specifically latest iPhone

at least 100 placed in different opposite locations like corners of the room

connect a power RF output amplifier. There is a lot of them based on Quorvo 4 pin chips and they cost around 10-20 usd. Check on www.aliexpress.com

no. check video description and github page for precise frequency range that can be used

no this is only for CC1101

100% not. You will need another library for this specific IC with specific instructions...

no you just need to plug it into the PC

@@justanengineer5599 Thank you for the clarification.

it has only on CC1101 chip and you can connect it to your mobile phone. Moreover the components cost 15usd not 75usd

to frequencies at the same time is not possible. But quick jumping between these two frequencies is possible. See my other video about the jammer

it would have to swipe between both frequencies. But yes it is possible

there is a field in the code that selects the base frequency. Watch the video carefully

uno uses 5v ttl logic so it is not good

@@justanengineer5599 if i use a TXS0108E TTL logic converter, can it work then?

yes. this one of the options. The other is to power arduino Atmega chip from 3.3V

of course. it works this way from the start. Pets will not stand this sound for a long time

single AD9833 generator has only one channel I am afraid. so the answer is no. you need 2 such devices

have you installed necessary files for Digispark in Arduino IDE ?

you do recording with URH and then implement the sequence manually in Arduino code

@@justanengineer5599 I record with the transmitter urh programmed to it?

watch the video carefully. 2 or 3 times.

better use cc11xx modules. NRF905SE does not allow to fine tune the frequency and only works in packet mode

@@justanengineer5599 awww man alr i already got then thanks anyway!

there must be poor contact between some pins. Try to solder the cables

@@justanengineer5599 They are soldered

If so, you may try to use next cc1101 board as something may be wrong with existing board

you can port this code easily just change the pin number

the brain can only be controlled by social media as tiktok, facebook, twitter, instagram. Thats the only way and moreover the most effective!

you have to test it For sure it shouldn't be used 24/7

@@justanengineer5599 Is there some kind of additional circuit so that this jammer can be used 24/7?

I think the option to detect human voice via microphone and jam it only when detected is a solution for this

use Universal Radio Hacker to see if it is a rolling code

@@justanengineer5599 Can I use the jammer mode (jam 1) and the receiver mode(recraw) at the same time? I want to make a rolling attack.

not. I would suggest to build two sets of this device and use them both at the same time

​@@justanengineer5599I made two sets of this device (to carry out the replay attack). One in jam mode One is also in the recraw mode The problem is that the recraw receives the jamming frequency and not the remote control data Do you have a solution?

setrxbw is the command that you should use to narrow the receive bandwidth not to get the jammer signal. Read issues tab for the project. I have already explained how to do it for other person

yes of course. But the point was to create something that anyone can build from publicly available components not some customized board

@@justanengineer5599 yes I see..but when you opened the case in the video it looked like it was complicated to solder...you must have spent a lot of time ..

In fact it was 2 hours of work

I am afraid you need to build it on your own

it is almost the same but my costs 10x less and everyone is capable to build it. the difference is that they may have battery built inside.

​@justanengineer5599 he mentions paper or cotton will block the jammer and the microphone will record as normal. Is the same true for yours? If that's the case, a microphone pop shield may easily block this

works quite well, try to build it

I am not a genius I am just an engineer. This is just an example how to use the knowledge in practice. Knowledge is power.

@@justanengineer5599 wow sir amazing work thank you so much for your reply I will show my friends all your vids as well

what do you want to pair it with? This device utilizes the effect that FM modulation of ultrasound leaks into audible band of the microphones

@@justanengineer5599 ok clear thanks

Depending on the device you want to jam and number of transducers. Can vary from 2 meters to 5 meters or more

I love it! I build one round with 140 transmitters. 12v 5a.i used Attiny85 usb. I work's 1m distance. Maybe need more amps. And it start to work after 8-10 seconds. I used one older code from yours too.

try to add IRF4115 mosfet, diode and bunch of coils. It increases the distance many times

check video description

it will do one big line, at least for showraw

I was using different antenna for Adsb. basically it was around 13cm long dipole as I recall. I had to replace antenna

yes. first you need to get windows working with your rtl sdr dongle. you may look for some of my old videos showing how to install driver with Zadig tool

@@justanengineer5599 Hey Adam, So I gave up on getting URH to work on Windows. I installed Debian 12 on an older laptop, and URH is working well on that. I am continuing to work on my Windows machine to complete this project. I am working on an ESP32 board. I have flashed the ESP32 with your .ino file for the ESP32 with no compiling errors. On my ESP 32 I can see a red and blue light lit steady (not flashing). I think this means I have uploaded it successfully. I then switch to Putty to communicate with your program. In Putty, I select the serial radio button, I enter my number for port COM# (in my case my device manager is telling me 5), speed I enter 115200 baud rate, data bits 8, stop bits 1, parity none, flow control none. When I open putty terminal. I only see a Green Square.. and not the (c) Adam Laboda.. any thoughts?

Okay, I changed my procedure a little bit. After Flashing the program, I press Enable on the ESP32, I disconnect the USB Cable from the computer.. wait a few seconds.. then plug it back in.. then open up Putty.. and it's almost working.. but the ESP32 keeps resetting over and over again..so I keep seeing your name roll up the screen along with..

It works! It works! Thank you, Thank you, Thank you! Wow.. it only took me like 3 weeks to get this working! In the end it was a stupid mistake.. In the sample code you provided.. the XIAO chip is the code that isn't commented out and the WROOM code is commented out.. I switched this.. everything is up and running.. just tried jamming.. cause that was the easiest thing to try first.. man.. such a sweet project.

I am glad you made it !

depends on the device you want to jam. For android phones 4+ meters for iphones half of it

you need to contact the author of this application and ask for adding this feature

jeśli zasilisz arduino z 3.3V to moze sie uda. Ale polecam zakupić coś z USB i 3.3v logika TTL
