Maritime Hacking Village
The DEF CON 33 Maritime Hacking Village edition whose official Differential Destroyer badge was OSHWA-certified and published as a Pico 2, maritime-bus, scripting, and voltage-glitching hardware platform.

The Differential Destroyer was Maritime Hacking Village's official DEF CON 33 badge, published as an OSHWA-certified open hardware platform for maritime bus work, scripting, signal interaction, and experimental voltage glitching.
Lifecycle
The badge combines a TFT display, joystick, buttons, NeoPixels, accelerometer, SAO connector, SD card, battery charging, and status LEDs around the maritime protocol circuitry.
The Rust firmware exposes a Rhai scripting engine over USB serial, with bindings for system, inputs, SAO, display, LED, accelerometer, battery, Trx/Rx, and CAN behavior.
The badge exposes differential receiver and injector circuits, switched voltage references from 0 V through 4 V, high-impedance mode, and operation up to 5 MHz.
Village-sold Differential Destroyer boards were documented as Pico 2-compatible and bundled with a Pico 2 flashed with current firmware.
OSHWA and repository documentation describe CAN 2.0B/NMEA-2000, NMEA-0183, and Modbus RTU transceiver modes with software-controlled half- and full-duplex behavior.
Operational history
The badge is included as a source-backed village badge without claiming attendee-wide DEF CON distribution or a final production quantity.
The record documents intended and exposed firmware surfaces without implying that every listed protocol or feature was complete during DEF CON 33.
The record remains source-backed and image-free rather than copying repository, OSHWA, village, social-media, or attendee imagery without complete provenance.
The catalogue presents the badge as a real fault-injection and maritime-bus lab while preserving the primary-source caution around unsafe use.
