RF • WIRELESS • DRONES / UAS • SECURITY • HARDWARE • CODE
A workshop for things that fly, transmit, authenticate, automate,
or probably shouldn't have been taken apart in the first place.
I'm Nezyx.
This is where I keep the projects, experiments, references, half-finished ideas, and occasionally questionable decisions that come from pulling on technical threads just to see where they go.
My interests tend to live somewhere between cybersecurity, radio, aviation, embedded hardware, physical security, and automation.
A lot of what ends up here starts with:
“I wonder if I can make these two things talk to each other…”
and deteriorates from there.
RF / SDR
Wardriving
Wi-Fi
HackRF
Flipper Zero
NFC / RFID
Meshtastic
ESP32
Raspberry Pi
Drones / UAS
Remote ID
OSINT
Physical Security
Automation
Wireless exploration, spectrum hunting, mapping, and experimentation.
SDR, HackRF, spectrum exploration, wireless protocols, wardriving, Wi-Fi, Bluetooth, Meshtastic, antennas, and generally figuring out what is transmitting around me.
UAS hardware, Remote ID, telemetry, RF behavior, embedded integrations, mapping, aviation technology, and experimental drone tooling.
Cybersecurity, OSINT, physical security, access control, NFC/RFID, digital forensics, vulnerability research, and security automation.
Flipper Zero, ESP32, Raspberry Pi, microcontrollers, sensors, radios, odd peripherals, and making hardware do things its manufacturer probably didn't document.
Python, APIs, Discord integrations, data gathering, bots, utilities, and glue code for connecting systems that weren't designed to work together.
A practical frequency reference for exploring the RF spectrum with HackRF and other SDR hardware.
Focus: RF SDR HackRF Spectrum
A curated collection of resources and techniques focused on vehicle-related open-source intelligence.
Focus: OSINT Vehicles Research
Discord-based OSINT tooling integrating OSINT Industries searches into an operational workflow.
Focus: OSINT Python Discord Automation
Research and experimentation involving StoryPod NFC tags, cards, books, and character tokens.
