Hello hacker friends, skids & noobs. Here is a complete Noob guide for how to make a WiFi/bluetooth/drone jammer for under $20. Now even your grandma can make this in a few hours.

Full instructions / Hardware files / firmware: https://github.com/dkyazzentwatwa/cypher-cc1101-jammer

This operates on the 2.4gHz frequency and does not do 5gHz. It operates on 1-125 channels — 1-14 is WiFi, 1-80 is Bluetooth 1-125 is for drones. It is a good way to test the security of your devices.

It uses 2 nRF24L01+PA+LNA radio modules for 2.4gHz communication and an ESP32 wroom 32E. However any ESP32 wroom/devkit with 2 SPI buses will work. 2 NRF will definitely jam, but 1 will still create decent interference. Get yourself these, and a breadboard/ jumper wires — or you can use my schematics/pcb files to make your own cool little portable device!

1. Gather together your parts — NRF24 x 2, ESP32, breadboard and wires.

2. *** Prep you NRF’s by adding a 10uF 16V-50V~ or stronger to the VCC & GND pins as shown in the pictures. This is 100% necessary if you want real performance. This is the only essential soldering step even if using a breadboard.

   1. The positive end of the capacitor goes to the VCC of the NRF, and the negative end of the capacitor goes to the GND pin of the NRF. Do this for both NRF modules.

3. Wire your modules as below and according to the pinout pictures: FOR DUAL/TWO NRF24L01

• HSPI= SCK = 14, MISO = 12, MOSI = 13, CS = 15 , CE = 16

• VSPI= SCK = 18, MISO =19, MOSI = 23 ,CS =21 ,CE = 22 FOR SINGLE/ONE NRF24L01 YOU CAN CHOOSE BETWEEN HSPI OR VSPI

• VSPI= SCK = 18, MISO =19, MOSI = 23 ,CS =21 ,CE = 22

• HSPI= SCK = 14, MISO = 12, MOSI = 13, CS = 15 , CE = 16

1. Now it is time to upload that lovely firmware from my boy smoochie! Here is the firmware link: https://github.com/dkyazzentwatwa/cypher-cc1101-jammer

2. You can install the firmware by two ways: web flasher(noob friendly but can’t customize code) or with Arduino IDE (little harder but can customize code)

3. With web flasher, you will connect your ESP32 to your phone, click on the web flasher link(safari not supported, I recommend Chrome), and select the type of configuration you desire. And you’re done! If it doesn’t work then check your wiring.

4. For Arduino, you will download the .ino in the INO folder and upload it to your ESP32 — look into Arduino IDE and how to get setup. You’ll want to be familiar if you want to customize the code.

5. And there you have it! If you wired everything correctly and soldered on the capacitors properly, everything should work perfectly. Feel free to experiment with the channels to get the desired output. Also, don’t forget to customize the antennas to enhance their performance. If you have questions let me know!

Starbeam PCB Assembly Guide

GitHub Project: https://github.com/dkyazzentwatwa/project-starbeam

This guide provides instructions for completing the Starbeam PCB assembly after the components have been manufactured and attached. You can source the necessary parts from various suppliers, but the provided links offer decent price points. It is crucial to obtain the exact specified parts if using this PCB, especially for the display and USB-C module. This is what you will get after PCB order: Project Starbeam PCBA

PCB-A Notes:

This is a 4-layer PCB, there are notes for the required specifications in /hardwawre This is an advanced project, so please do not waste your time & money if you do not understand PCB ordering, & if you need any assistance you can book a call & i'll be more than happy to walk you through the whole build process: Book a 30 Minute Consultation

Required Components After PCB Assembly:

ESP32-Wroom-32D: https://amzn.to/3YR1noR

SSD1306 128x64 0.96-inch Display: https://amzn.to/4lONdP9

NRF24 Radios (x5) for 2.4GHz: https://amzn.to/4iBofjl

CC1101 Radios (x2) for 433MHz: https://amzn.to/4iuopZH

USB-C Module: https://amzn.to/4lKZ5BL

Software Setup & Code Upload:

Download Arduino IDE: Get it here: https://www.arduino.cc/en/software/

Install Arduino IDE: Refer to the installation guide: https://docs.arduino.cc/software/ide-v2/tutorials/getting-started/ide-v2-downloading-and-installing/

Open the Code:

• Extract the starbeam code .zip file.

• Extract SmartRC-CC1101-Driver-Lib2 2.zip & add it to your Documents/Adruino/libraries/ folder. This must be added to use the 2nd CC1101 radio module!

• If you are creative, you can also add up to 5 CC1101's for advanced testing. -Open the starbeam .ino file. This will automatically open the code in Arduino IDE.

• Upload Code to ESP32:

• Upload the code to your ESP32 microcontroller using Arduino IDE.

• Note: Videos on uploading code and using Arduino IDE are available in the Hakr Hardware Club (https://whop.com/little-hakr).

• Final Steps: Attach the antennas that correspond to your desired setup. Good luck...

Here I am, just casually running my listener on my vps.. when suddenly.. BAM! Not JUST China.. but Russia decided to run a scan on my server 😂😂 like you guys aren’t even trying to hide it anymore 😂😂

Been spending a couple of months tinkering with a DIY multi-node wireless security rig, and I finally got the hardware coordination working smoothly.

The project uses a mix of ESP32 boards to look at how modern networks handle disconnections and roaming. I'm using an ESP32-S3 (with 8MB RAM / 16MB Flash) to spin up a clone access point, while an ESP32-CAM(Master) handles the orchestration alongside a couple of standard dev boards(Slaves).

The interesting part was tackling WPA3. Since WPA3 mandates Protected Management Frames (PMF), traditional layer-2 deauth frames don't really cut it anymore. To work around this and test client reconnection behaviors, I integrated two NRF24L01 modules to introduce a highly localized, 1-second burst of 2.4GHz RF disruption. The goal is to see how the WPA3 handshake and roaming mechanisms react when forced to re-authenticate under sudden signal loss just after triggering the SA query mechanism causing clients to be kicked out from the network by the Ap itself and never connecting back thanks to the evil twin Ap.
