Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
dratini0's legacy adapter connects Tildagon to SAO, TiDAL, and QW/ST-style expansion traditions, showing that add-ons also serve compatibility and reuse.
SourceThe hardware list includes one 1.69bis SAO port plus conductive pads, 3.5 mm lead, elastic band, lube, custom lanyard, spare batteries, and battery clip.
SourceThe official DC34 SAO specification documents 3.0 V VDD, 100 mA tested total supply across both SAOs, GPIO pins, I2C devices at 0x3C and 0x19, and mirrored unkeyed 6-pin SAO headers.
SourceThe badge documentation identifies I2C expansion configured as DEF CON SAO plus USB terminal access for I2C and SAO sensor interfacing.
SourceThe badge includes an SAO connector that supports I2C, UART, CAN Bus, and more; the DC33 release explicitly adds Aerospace Village DC33 SAO support.
SourceThe README lists a Shitty Addon connector, making the badge compatible with the wider SAO-style add-on ecosystem.
SourceThe 2022 hardware tree includes multiple SAO directories, including Ubisoft, numbered SAO revisions, BOMs, Gerbers, assembly exports, and board-source material.
SourceThe MiniBadge standard defines I2C read/write initiation, button, text, score-update, and brightness messages, while warning that microcontrollers need to track state across repeated starts and stops.
SourceThe minibadge notes define I2C address coordination plus polling, button, text, pixel, timed-pixel, custom-data, score-update, and brightness-change messages.
SourceThe CHV SAO spec provides 3.3 V and ground while replacing normal SAO I2C with CAN TX and CAN RX for vehicle-network add-ons.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, while this 2020 record keeps per-board behavior limited to recovered source evidence.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, while this record keeps per-board firmware claims limited to recovered 2021 evidence.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, but this record does not claim every 2023 entry implemented active I2C behavior.
SourceThe public MiniBadge standard documents +VBATT, 3V3, GND, SDA, SCL, CLK, PROG, and NC pin guidance, including +VBATT voltage caution and do-not-connect rules for reserved pins.
SourcePOC Security's official update trail described a Zer0Con2025 Entry badge with 100 available seats.
SourcePOC Security's official update trail described a Zer0Con 2024 Entry badge with 120 available seats.
SourcePOC Security's official update trail described Zer0Con2026 registration as limited to 120 seats.
SourceThe official registration pages say the issued badge gave access to all talks and workshops.
SourceThe wiki preserves alternative software links for Tetris Sound Track, TV-Bunny, and Ethersex, showing the badge as a small AVR software target beyond the default firmware.
SourceThe Safe Mode badge was a real cassette tape in a jewel case, with side A/B markings, label art, and audio content that formed part of the challenge.
SourceThe assembly guide documents a 555 timer, photoresistor, capacitor, resistors, LED, AAA battery holder, and wiring; testing confirms the LED blink speed changes with light exposure.
SourceThe official badge was a playable vinyl record, making audio playback and record inspection part of the badge-hacking surface instead of firmware or active electronics.
SourceThe radio badge used RF gain control, a small transistor amp, mono audio sent to both headphone channels, and a hackable AM tuner path.
SourceBuilders could adjust the potentiometer to control how dark it needed to be before the badge lights turned on.
SourceAttendees could append JavaScript apps to `Badge.apps`, add LED patterns, upload code over BLE, and persist extensions in `.boot0` through `.boot3` storage files.
SourceThe getting-started and software pages link the Bangle.js App Loader and app repository as the public app-distribution surface for the watch.
SourceThe MK4 wiki documents installing apps directly on badge through the Badge Store app: choose Install, pick a category/app, save it, then restart back to the launcher.
SourceSHA2017 used the Badge.Team Hatchery path for discoverable badge applications, and the current Hatchery index still exposes SHA2017-compatible project records.
SourceThe MCH2022 Hatchery catalogue made app discovery and installation part of the camp badge workflow rather than a post-hoc source dump.
SourceThe EMF 2022 Hatchery API still lists TiDAL categories across event, game, graphics, hardware, utility, data, silly, unusable, and adult apps, preserving the badge as an app ecosystem rather than a one-off PCB.
SourceThe live app directory makes Tildagon a post-event software platform, with badge, background, game, media, music, pattern, hexpansion utility, schedule, WiFi, and sensor apps published by community authors.
SourceApps were submitted by adding a folder with main.py metadata headers to the Mk4-Apps GitHub repository, validating with tilda_tools, and opening a pull request; official rules banned malicious apps and code/image hot-loading without good reason.
SourceNew apps are published by adding a TOML pointer under the flow3r-apps index and opening a merge request; after merge the app appears in the public directory.
SourceThe app index treats a commit that increments metadata.version in flow3r.toml as a new release, making post-camp app maintenance part of the badge lifecycle.
SourceThe repository setup flow flashes a CircuitPython UF2, then copies the RP2350 filesystem to CIRCUITPYTHON for the badge runtime.
SourceThe official archive and sponsorship kit prove the electronic badge's event and sponsor context, but do not expose component-level hardware, firmware, artwork, or production files.
SourceJay Turla / @shipcod3's public post preserves the ROOTCON 12 Electronic Badge title, but this pass did not recover a public schematic, firmware archive, BOM, or rights-cleared image.
SourceThe OPCDE Kenya agenda preserved a dedicated session on making the AfricaHackOn 2018 Electronic Conference Badge, anchoring the badge's existence while leaving the technical archive open.
SourceLater writeups treated the 2019 badge as an ESP32-WROOM-32U board suitable for C# NanoFramework and ESP32 game/video experiments.
SourceThe official about page describes the merch bundle as a shirt, electronic badge, and sticker bundle, supporting an electronic-badge classification while leaving component details unknown.
SourceTwinkleTwinkie's DEF CON 27 Hardware Hacking Village bio explicitly names BSides Vancouver 2019 Badge among notable produced works.
SourceSOLDER LVL2, SOLDER LVL3, SOLDER LVL4, and Puzzle Badge entries document a tiered soldering and puzzle MiniBadge trail designed by Rushan.
SourceThe 2023 data includes through-hole and surface-mount difficulty notes, parts lists, LED/resistor builds, and acquisition guidance, while the official FAQ encourages newcomers to learn MiniBadge design.
SourceThe guide covers LED orientation, two-position headers, through-hole and SMD soldering, reverse-mount LEDs, RFID sticker placement, motor/fan parts, hot glue, cable-test behavior, and ATTiny programming for selected MiniBadges.
SourceHeatSync Labs brought acrylic backs, coin batteries, LEDs, resistors, and badge lanyards so attendees could solder a working LED badge at the booth.
SourceThe assembly guide says attendee conference bags contained the badge PCB, passives, fuses, headers, D1 Mini ESP8266 board, USB battery, and exchange token for HHV display parts.
SourceThe forum narrative says the team used solder paste, a hotplate, and manual display insertion to finish about 500 functional badges before the party.
SourceThe official badge section says each participant could design a custom configuration for their badge.
