Смысл: The main idea is to demonstrate that a deep understanding of hardware specifications and protocols allows for the creation of a highly efficient RFID emulator using minimal components and unconventional microcontroller operation.
A technical tutorial on building a passive 125kHz RFID emulator using an ATtiny85 microcontroller that is powered and clocked directly by the reader's magnetic field.
Смысл: The main idea is to demonstrate a high-level 'overengineering' feat by recreating a modern wireless identification device (RFID tag) using basic discrete logic components instead of integrated microchips. It serves as both a technical exploration of the EM4100 protocol and a showcase of hardware engineering skills for a specific hobbyist competition.
An engineer builds a fully functional, passive 125kHz RFID tag using only 7400-series logic chips and discrete components instead of a microcontroller.
Смысл: The author describes the creation of a portable RFID spoofing device based on Arduino that can store and emulate multiple 125 kHz door entry keys, allowing the user to replace a bunch of key fobs with a single electronic device.
A technical guide on building an Arduino-based device that emulates multiple 125 kHz RFID keys to unlock building intercoms.
Смысл: The main idea is to demonstrate how to create a functional, low-cost electronic door lock using an Arduino microcontroller and RFID technology for contactless access control.
A technical walkthrough of creating a DIY RFID-based door lock using an Arduino Pro Mini, RC522 reader, and a servo motor.
