Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The badge README and firmware document a Wi-Fi configuration mode where the badge displays an SSID and password, then hosts a configuration flow for network settings and the custom message.
SourceThe public talk describes USB-C, a CH340 USB-UART bridge, battery-voltage monitoring, and onboard charging/protection circuitry.
SourceReturning badge features included capacitive touch buttons, 2.4 GHz connectivity mostly as a Wi-Fi node, remote connectivity via IRC, and a serial interface.
SourceNodeWatch documents Chrome/Web Bluetooth programming through the Espruino Web IDE and links bridge examples for connecting watch behavior to other systems.
SourceChallenge solvers could receive a Challenge Accepted SAO; the writeup says only two were awarded, one for crypto and one for the counterfeit-badge contest.
SourceThe 2023 data export lists contest-category entries including Lockpick Village, Tamper Evidence, and Hackers Challenge records, preserving acquisition routes tied to challenge activity.
SourceThe listing names a pre-flashed ATMEGA328, 16 MHz crystal, two capacitors, resistor, two through-hole tactile switches, power switch, and AAA battery holder. It says three AAA cells are required but not included, without publishing wiring, voltage, charging, or a complete assembly guide.
SourceElectronic Cats recommends soldering the ESP32 Wemos D1 module for the best badge experience, with OLED-routing jumpers available when moving display control from CH32 to ESP32.
SourceThe badge used multiple buttons for menu and challenge interaction, with GPIO support preserved in the public firmware.
SourceThe Mini Cyberdeck documentation and firmware notes describe interaction with the earlier BCD-0o27 badge.
SourceThe seller says Submarine interacts with BigTaro's Gunslinger-B-Gone for extra fun. It does not say whether that interaction is electrical, infrared, radio, software, physical, optional, bilateral, safe, interoperable across revisions, or available at the scheduled drop.
SourceThe 2025 CH405 Labs firmware post publishes the BalCCon2k24 BCD-0o27 image with a Pong routine that lets the 2023 cyberdeck play against a human through a connected MC-0o00.
SourceThe official site offers remaining 2025 E-Badges through 2026 ticketing and instructs buyers to pick them up at the April 2026 conference.
SourceBadge Pirates said it ported a Lunar Lander contest to last year's BSidesKC badge for the April 2026 Ad Astra programme, told owners to bring that badge, and expressly said there was no new hardware. The announcement does not prove an individual badge was reflashed or used at the event.
SourceThe Euphoria CTF page says the first challenge is on the badge after Shady Tag registration at the Shadytel Experience Center.
SourceBadge.Life's live DC34 Village Schedule lists Masonic33 Badge — heal at 10:30 AM Friday August 7 and 11:00 AM Saturday August 8, 2026.

SourceThe reviewed official event home, HOPE Wiki main page, schedule, and ticket listing do not identify a HOPE 26 physical or electronic conference badge. The known digital admission ticket is retained as an identity artifact rather than upgraded into hardware.
SourcePayment Village's official 2026 programme schedules Introduction to the Vulnerable ATM Badge on Friday and Saturday. This identifies an ongoing instructional reference only; it does not state that the 2025 object will be issued again, demonstrate its final 2025 configuration, or connect it to a 2026 volunteer credential.
SourceThe Build-A-Badge software lets users choose images, configure LED patterns, set a badge name, program the device, and upload WASM applications.

SourcePunk Security's own historical event listing identifies it as BSides Newcastle's 2024 badge sponsor and says it would present the making of that year's badge; its public repository identifies the Little Shop of Horrors Plant Badge and says it was given out at BSides Newcastle. This establishes a maker-side event association without claiming organizer confirmation or that every attendee received a unit.
SourcePunk Security's own historical event listing identifies it as BSides Cheltenham's 2023 badge sponsor, says it would talk about building the BSides Delorean badges, and calls them functional conference badges; its public repository identifies the Delorean Badge. This establishes a maker-side event association without claiming organizer confirmation or that every attendee received or completed a unit.
SourceA June 6 commit changes the default badge identity title in the repository source to 2026. It is direct evidence of a 2026 software revision, not evidence that the current tree was flashed or run on a particular physical e-badge.
SourceThe Eagle schematic and board preserve SWD, UART, I2C display/front connectors, jumpers, and a four-pin right-angle header for badge hacking and add-on work.
SourceThe schematic maps J1 to VCC, GND, RST, PWM0, PWM1, CAP0, and CAP1-related nets, preserving a six-pin header trail for programming or badge hacking.
SourceDAP mode presents the badge as a CMSIS-DAP probe for pyOCD, OpenOCD, Keil, and SWD target debugging while keeping a CLI serial interface available.
SourceSkyler Mansfield's Goosespansion is a named PCB hexpansion with published files, showing how the Tildagon gallery tracks both creator attribution and reusable fabrication data.
SourceTiff's Ducks hexpansion records the purely expressive side of the ecosystem: camp-lore ornamentation using the same connector format as active electronics.
Sourcelornajane's Petals use multiple decorative hexpansions around a badge, illustrating how the connector can turn the badge silhouette into a larger wearable object.
SourceThe August 7, 2026 build guide, committed during DEF CON 34, addresses purchasers directly, states each badge is pre-flashed with firmware and should be good to go, identifies the shipped Gateron Blue switches, and documents assembly and key functions. It evidences maker-documented delivered units without a production count, recipient ledger, or sale-channel record.
SourceThe 2018 badge software turned the device into a BASIC and CP/M/Z80 playground for demoscene entries, games, music, serial experiments, keyboard apps, color-display work, and flash-storage hacks.
