Portable drone jammer uses a Raspberry Pi tactical Software Defined Radio
Originally published on tomshardware.com by Ash Hill on 24 November 2024
Media-Grizzly’s D.E.S.E.R.T Pi-Powered Tactical System is a Raspberry Pi project that pushes the boundaries of portable technology with its dual functionality as a software-defined radio (SDR) system and a drone jammer. Housed in a compact, portable case, this project combines technical prowess with tactical practicality, making it a standout in the Pi community.
The system is built around a Raspberry Pi 4B, though it can be adapted for use with other Pi models, including the Pi Zero and potentially the Pi 5. Accordingly it features a custom laser-engraved faceplate that incorporates a keyboard, USB port, power LED, LCD display, and a distinctive “DE-AUTH” red switch. This switch is central to the project’s functionality, allowing users to disable nearby drone signals when armed and activated via a connected antenna. Media-Grizzly emphasizes that this feature is theoretical and subject to local laws regarding signal interference.
Power Usage
In terms of power, the system runs on a 12V battery pack, regulated to 5V using a buck converter. The Raspberry Pi draws approximately 5 watts, while the full system requires about 17 watts. Future enhancements include the integration of an Adafruit INA219 to provide real-time power monitoring on the LCD screen.
While the full source code has not yet been released, Media-Grizzly has indicated plans to share it on GitHub. For those interested in replicating or modifying the D.E.S.E.R.T system, Media-Grizzly’s Reddit thread offers additional insights and updates.
The D.E.S.E.R.T Pi-Powered Tactical System exemplifies how Raspberry Pi projects can combine utility, creativity, and experimentation to create unique, multifunctional tools. It also serves as a reminder to consider legal and ethical implications when developing technology with potentially sensitive applications.
