SourceThe stock firmware included a Z80 emulator running CP/M with classic software hooks such as Zork and Sargon, turning the badge into a tiny retrocomputer.
SourceThe page says the badge can be used as a normal Meshtastic node after the event, keeping the artifact useful beyond DEF CON 33.
SourceThe badge reused surplus ZBD 55c-RB / EPOP55 electronic shelf labels with CC1110 control hardware and a bistable LCD that keeps its image without power.
SourceThe Bot jewel boosted power for four large servos and was documented as the building block for turning Ph0xx into a bipedal robot.
SourceThe Ph0xx documentation points toward turning the badge into or mounting it on a robot using its hardware and mounting holes.
SourceMarc Merlin's first-hand report documents a Donkey Car kit with an onboard camera connected to a Raspberry Pi and a custom last-minute Raspberry Pi HAT.
SourceMarc Merlin's first-hand report identifies the 2020 DingoCar as controlled by a Raspberry Pi and shows it as the hardware focus of the Open Hardware Miniconf.
SourceEkoparty's official attachment pages preserve attendee, speaker, and workshop badge-art variants for the 2021 set.
SourceHuman, Goon, Press, Speaker, Vendor, Contest Organizer, and Uber badge shapes could be placed together as a puzzle, and Smitty & The Minions / Team Halibut earned honorable mention for combining all seven badges with modified firmware animations.
SourceThe badge how-to and orga notes preserve safeR, orga, participant-name-sign, and area-owner context for different visible badge roles.
SourceJonTheNiceGuy's Now & Next app shows current and upcoming EMFCamp stage items, carrying the badge from novelty hardware into a live event companion.
SourceAttendee feedback explicitly called out the lack of an official badge challenge, so the record treats DEF CON 25 as a non-puzzle standard-badge year.
SourceThe badge challenge used ARM TrustZone separation with non-secure and secure stages, command-line interaction, snake warm-up behavior, and unlock states.
SourceGrand Idea Studio links post-event research into over-the-air remote code execution against the badge's NFMI subsystem.
SourceThe README describes an AD8317 RF detector path that measures RF signal strength, displays results on the OLED, and is intended to detect hidden wireless devices.
SourceThe AMG8834 breakout turns the badge expansion interface into a small thermal-camera experiment.
SourceThe specification documents a LIS3DHTR accelerometer, LiPo voltage monitoring, DW01A protection, TP4056 charging, TPS63060 buck-boost conversion, and a PWM buzzer.
Sourcewebboggles' Seismograph app turns the onboard IMU into a live waveform and Richter-readout instrument with auto-scaling and axis cycling.
SourceThe board exposed BME280 and ADXL345 I2C sensors, screw-terminal ADC inputs for soil moisture, DS18B20, PIR, WS2812B LED strip support, and a switchable VSens rail.
SourceThe badge exposes BME688 gas/pressure/humidity/temperature sensing, MQ-3 alcohol sensing, XYZ position, infrared receive/transmit, RTC, buttons, LEDs, speaker, and full-color display for ICS exercises.
SourceThe production CSV identifies an IRM-H638T IR receiver and an LSM6DS3TR-C motion sensor, grounding the badge's IR and movement-scoring surfaces in the hardware archive.
SourceThe badge page documents CP2102 USB-to-UART access, /dev/ttyUSB0 discovery, PuTTY, and 9600-baud serial connection guidance.
SourceThe current official B|Sides Vancouver site anchors the Vancouver Security BSides lineage and location while this 2019 badge record remains constrained to recovered badge-specific evidence.
SourceThe guide walks Linux users through dmesg and ttyUSB0, macOS users through ioreg/system_profiler and tty.usbserial, and Windows users through COM-port discovery before connecting at 9600 baud.
SourceThe badge advertised itself over BLE with a 1-7 ID and included radar and badge-list screens for discovering nearby badges in camp.
SourceBadgeBuddy counted unique nearby BadgeBuddy BSSIDs every 30 seconds and adjusted the animation density to reflect nearby badges.
