hi, I bought for mistake the module HC-12 insted the CC1101, can I make this project with that transmission module? (I bought the arduino nano and TXS0108E TTL logic convertr)
I have a m1101d here and it’s connected to my arduino nano. I am trying to program it to where it can be 315 MHz as it has a cc1101 chip and is able to do this according to seller. How would I do this?
Hi! UNO boards have a 3.3V output pin, can i use UNO boards for this project? I tried searching in your github repo but there was no instructions about uno boards
Is it possible to go with 20khz from one channel of the amp and 25khz from the other channel to cover a wider range of mics? Unclear if the signal generator could handle this, but if you had two of them, could you feed each frequency to a different audio channel and amplify both at once?
I am trying to do this project with an Pro Micro 3.3v, but it sometimes gets hung up on cc1101intialize and when it doesn't it says "cc1101 connection error! check the wiring." I have triple checked my wiring and can't find any problems. Any help would be appreciated.
hello Im new to electronics but once its all put together and wired up and has the right modules when you plug it in to a Mac should the windows the control the modules pop up and what frequency do you use to black a radio signal the same as the brain thnx!.
Hello Thank you for publishing such a code. The remote control data received by recraw (milisec) changes every time it is received (due to the security mechanism used). Any ideas for this problem?
@@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
hello really excellent work, it would be possible to also bring together all the small electronic elements like inductance, resistance etc... on one and the same cms plate for example which would re-connect the others like the amplifier..the random generator
@@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 ..
Good for big company confidential conversations. "Everyone please place your smartphone on the table in front of you..... *click* and now we can talk" :)
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.
When I use your universal CC1101 interactive tool my addraw and showraw displays as a single line across the screen whereas your video shows it as block of lines. Is there a setting I need to make in order to display in a block on the page and not one long line?
When you say you have to adjust your antenna to receive Adsb transmission, what do you mean? I’m not getting any adsb so not sure if I’m doing something wrong
Thank you for putting together these great videos. I am having some problems getting this working. My main issue is with URH. I do not see any signals. I've tried different Antenna's, I went through all the possible settings, I've changed everything. Adding and removing a low noise amplifier. But it must be.... that URH on my Windows 11 is not working properly. Because when I close the software, and open up SDR#, I can see all the signals on their respective frequencies.. my vehicle FOB (315Mhz), my weatherstation (433.92 Mhz) and my garage door opener at 314.6 MHz. Do you have any suggestions on how to get URH to be able to see these same signals?
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. Thank You! // defining PINs set for ESP32 module // Example for XIAO ESP32 C3 /* byte sck = 8; // GPIO 8 byte miso = 4; // GPIO 4 byte mosi = 10; // GPIO 10 byte ss = 20; // GPIO 20 int gdo0 = 21; // GPIO 21 int gdo2 = 7; // GPIO 7 */ // defining PINs set for ESP32 WROOM module byte sck = 18; // GPIO 18 byte miso = 19; // GPIO 19 byte mosi = 23; // GPIO byte ss = 5; // GPIO 5 int gdo0 = 2; // GPIO 2 int gdo2 = 4; // GPIO 4
The source code allows to use this frequency but I do not think the chip can handle this. You would have to build an ordinary old LC based generator for this
