Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
John Rogers and Ben Eriksson's Fluroclock app controls an EMF installation from the badge, showing Tildagon as a controller for camp-side media hardware.
SourceThe 2023 writeup documents side connectors for badge chaining, optional OLED feedback, buttons, RGB LEDs, and point-scoring badge-to-badge interaction.
SourceThe repository documents a 0.96-inch 128x64 SSD1306 OLED, WS2812B RGB LED, LTR-303ALS-01 ambient-light sensor, and four directional buttons.
SourceThe Disobey 2020 docs describe Gameboy-inspired touch buttons, a launcher opened with START, a nickname app, and an on-badge keyboard with input, cursor, and confirmation modes.
SourceThe repository documents a serial CLI and four CTF flags hidden in the badge.
SourceThe README documents light sensing via LED2, left/right vibration motors, quiet sound generation through vibration motor PWM, accelerometer readings, and magnetometer readings.
SourceThe maker archive describes a compass mode built around a three-axis magnetometer, with an intentionally coarse bearing indication and magnetic-environment limitations. This preserves feature context without asserting calibrated accuracy, user outcome, or final-unit parity.
SourcePunk Security's event listing and repository describe an infrared-capable feature and source material. This preserves high-level functionality provenance without publishing use, configuration, targeting, payload, timing, operating, modification, or device-interaction instructions or claims.
SourcePunk Security's repository calls the Plant Badge a working soil sensor. This preserves the source-described feature at a high level without publishing sensing procedure, calibration, measurement accuracy, environmental limits, safe operating conditions, field result, or a universal user experience.
SourceFour PCB-integrated resistive touch sensors control sample triggering, sequencer behavior, pitch shifting, and filtering through RP2040 ADC readings.
SourceThe public firmware documentation describes nine per-key WS2812B LEDs and six SK6812 edge LEDs, plus tilt-reactive colour changes, shake-to-cycle patterns, and per-key ripple effects using an MSA301-compatible accelerometer.
SourceThe programme invited attendees to explore the Infocomm Z-Machine simulator with I/O on the USB CDC console and optionally program the badge.
SourceThe badge pairs an LCD with USB Device Firmware Upgrade support for reprogramming.
SourceDocumented display tabs include main H2HC 2018, dev status, last BLE message, raw debug text, and name pages.
SourceThe README documents USB CDC, controller/HID-capable USB behavior, an SAO port, and marked GPIO. It does not identify a supported add-on ecosystem, compatibility list, or final per-unit wiring revision.
SourceThe Tanmatsu manual documents internal personality modules as hot-swappable boards that can be exchanged to change device behavior while preserving the same handheld base.
SourceThe related Jr Hacker badge used an ESP8266 platform with IR tag gameplay, speaker, vibration motor, and WS2812 hit counter, with source material preserved under shark-badge.
SourceThe current kit inventory and DC32 guide enumerate three addressable LEDs, five blue LEDs, one bright white LED, eight 47 Ω resistors, three capacitors, a 3.7 V / 1,200 mAh LiPo, battery adhesive, JST/PH wiring, and board-to-board headers. The guide calls for through-hole assembly and battery wiring, not a safe modification or battery-service authorization.
SourceThe official 2026 sponsorship package says lanyards allow participants to hang badges around their necks and that the lanyard package includes the badge for about 600 items.
SourceThe official ROOTCON 15 Artwork/lanyard directory lists lanyard_front.jpg and lanyard_back.jpg, preserving the event's lanyard artwork trail.
SourceThe official ROOTCON 17 Art directory lists lanyard_single.png as public event lanyard artwork.
SourceThe badge used a Cat-5 cable through the board as a LANyard switch, making the physical lanyard part of the badge interaction.
SourceThe official sponsor page names CyberSec People as sponsor of the BSides Melbourne 2020 lanyards.
SourceThe official 2024 prospectus lists lanyard sponsorship as sold and sponsored in the conference-items sponsorship inventory.
SourceThe Hacker Couture DEFCON 33 list repeats Dante's Inferno Badge at $100 with the core three-board, sixty-LED, CR123A, and one-SAO-port description. This is retained as a later vendor-list recurrence of the DEF CON 32 artifact, not a duplicate DC33 badge, scheduled drop, organizer-issued item, confirmed stock, completed purchase, handoff, or attendee allocation.
SourceThe maker page describes online leaderboard score syncing over LoRa if RF conditions permit, with QR-code encoding of game data as the documented fallback.
SourceThe attendee report links a designer-authored reverse-engineering guide and a second programming guide that used avrdude, avr-gcc, and C examples.
SourceThe official 2026 badge documentation says its Badge Link / Blaster connector is compatible with the 2022 Time Blaster and the 2024 Big Flamingo Gun 9000.
SourceThe repository README says the hardware is released under CERN Open Hardware Licence v1.2 and links the project LICENSE text; the scope is kept to hardware documentation.
SourceThe repository includes an Apache-2.0 license file for its published source tree, while this catalogue still leaves the hero image empty until a specific reusable photo or upstream render is cleared.
SourceThe Hackbat documentation lists four WS2812 smart LEDs on the badge board.
Sourcemich181189's ArtNet Receiver turns Tildagon into a networked lighting-control receiver, with the app-directory description explicitly warning that the first release is janky and hard-coded.
SourceThe recovered first-hand report describes the badge as fancy hardware for speakers and friends, so the record does not claim general attendee distribution.
SourceSemiTO-V stated it would bring 25 badges to the Developer Zone workshop and later reported a logistics problem that prevented intended June 8 distribution. The sources establish a limited 25-unit Developer Zone badge run in planning and a real physical-board project, not a completed allocation ledger, attendee-wide issue, or confirmed recipient count.
SourceThe organizer's post-event account says only about five manually assembled advanced badges were prototyped after the planned automated-assembly path did not result in a fully assembled badge for every attendee.
SourceThe WWHF e-badge page says the 2025 electronic badge was sponsored by Antisyphon Training.
SourceHackRVA describes the RVAsec electronic badge programme as a recurring badge-team effort with schedules, games, and surprises.
SourceThe official villages page describes a Badge Museum documenting NorthSec's long-running electronic-badge history and open-hardware culture.

SourceU.S. Army coverage identifies the 2024 8-8-8 badge as AvengerCon's first electronic badge.
SourceCisco's 2015 write-up frames SAINTCON's show-badge program as having run across the prior two years, supporting 2014 as part of the event's early badge lineage.
SourceThe writeup explicitly planned to make badges a mainstay at future AfricaHackOn conferences, move from about 20 selected units to all attendees, and transition to a professional PCB.
SourceAoSC describes Micro-USB, one large touch pad, three NeoPixel groups, a small speaker, and no battery. The linked Coin M0 profile instead describes native USB-C, three capacitive touch pads, three RGB-NeoPixel groups, and a speaker. The shared lighting/audio concepts are source-backed, but the exact connector, touch count, board revision, LED count/current, speaker part, power path, and final 2026 configuration remain unresolved.
SourceThe source maps a left multi-press mode selector, right Attack/Trigger switch, four color-coded status LEDs, optional 9600-baud UART debug output, and ATtiny1614 serialUPDI programming context. The README gives an avr-gcc/ATtiny device-pack/avrdude outline and says a later convention reflash may happen, but no supported end-user programmer, fuse configuration, tagged release, update package, recovery guide, or warranty is published.
SourceCisco Connected Mobile Experiences data supplied the venue-location context used to personalize badge behavior and analyze attendee movement.
SourceNodeWatch and NearForm document TensorFlow Lite for Microcontrollers experiments for gesture recognition on the watch, with a public model notebook and application examples.
