Seeded artifacts
JavaScript hackable BLE badge
An open-source hackable JavaScript badge for NodeConf EU 2017 in Kilkenny, built by NearForm around Gordon Williams' Espruino/Puck.js lineage with BLE, LCD, NFC, buttons, CR2032 power, attendee-name programming, code examples, and challenge behavior.
Pixl.js JavaScript badge with RGB, sensors, and expansion headers
An Apache-2.0 archived NearForm badge for NodeConf EU 2018 in Kilkenny, based on Pixl.js and Espruino with LCD, Bluetooth programming, RGB lighting, vibration motors, light, accelerometer and magnetometer APIs, extension headers, apps, patterns, and attendee name tooling.
Bangle.js JavaScript and TensorFlow smartwatch badge
A NodeConf EU 2019 attendee smartwatch badge built around the NodeWatch/Bangle.js open-source JavaScript watch platform, with Espruino programming, nRF52832 BLE hardware, colour LCD, sensors, GPS/Glonass, app loading, and TensorFlow Lite gesture experiments.
Irish STM32 touch-and-sound electronic conference badge
A source-backed BSides Dublin 2026 Harp Badge: the organizer-owned public repository preserves firmware, a hardware reference, production files, and a post-event update path for the May 23 Trinity College conference.
Maker-documented ESP CTF challenge badge
A public maker archive explicitly titled Women's International Cybersecurity Challenge Badge 2026 links itself to WICC and documents a hackable serial-CLI CTF badge with ESP8266 and ESP32 target trees, challenge activities, a two-part protective case, and a repository photo of a physical cased device. WICC's official site and Cyber Ireland's post-event recap confirm the completed July 9-10 Dublin competition, but neither organizer source names this exact project. TOG separately reports building 15 ESP8266 hardware flags for the same CTF without identifying them as this archive, so this is a maker-documented event-linked electronic badge—not an organizer-issued credential, general attendee badge, or claim of equivalence to the flags.
Events
The November 5-8, 2017 NodeConf EU edition in Kilkenny, Ireland, whose attendee badge was a NearForm/Espruino open-source hackable JavaScript badge.
The 2018 NodeConf EU edition in Kilkenny, Ireland, whose attendee badge was a NearForm Pixl.js/Espruino hackable JavaScript badge with public code and hardware design files.
The 2019 NodeConf EU edition at Lyrath Estate in Kilkenny, Ireland, whose NodeWatch/Bangle.js open-source smartwatch badge is documented by NodeWatch.dev, NearForm, Espruino, public app/workshop repositories, and attendee reporting.
The May 23, 2026 Irish Security BSides edition at Trinity Business School whose organizer-owned Harp Badge repository preserves STM32 firmware, hardware reference material, and manufacturing data.
The completed July 9-10, 2026 inaugural Women's International Cybersecurity Challenge in Dublin. WICC's official site establishes the two-day venue and advanced hardware-security CTF context, while Cyber Ireland's July 17 recap confirms the completed competition. A public maker archive explicitly identifies a WICC 2026 CTF badge, but organizer sources do not name that exact project or establish organizer issuance or attendee-wide distribution.
Lifecycle
Attendees could append JavaScript apps to `Badge.apps`, add LED patterns, upload code over BLE, and persist extensions in `.boot0` through `.boot3` storage files.
The getting-started and software pages link the Bangle.js App Loader and app repository as the public app-distribution surface for the watch.
The README links name-changing tools and explains how badge owners could make the badge connectable via menu item or button-held boot modes.
NodeWatch documents Chrome/Web Bluetooth programming through the Espruino Web IDE and links bridge examples for connecting watch behavior to other systems.
Hackaday reports a Konami-code sequence, hidden behavior, and a Grand Challenge for hacked badges during the event.
The repository documents USB DFU flashing with `dfu-util`, a recoverable bootloader, and a manual bootloader override by holding touch strings 1 and 6 while connecting USB.
J1/J2 exposed GPIO and analog pins, while J3 provided an ESP8266 ESP-01 serial/Wi-Fi header with a documented mirroring caveat and wiring workaround.
The repository hardware directory exposes Eagle schematic and board files plus exported PDFs for the badge design.
The repository documents a serial CLI and four CTF flags hidden in the badge.
The README documents light sensing via LED2, left/right vibration motors, quiet sound generation through vibration motor PWM, accelerometer readings, and magnetometer readings.
NodeWatch and NearForm document TensorFlow Lite for Microcontrollers experiments for gesture recognition on the watch, with a public model notebook and application examples.
The production archive provides Gerbers, BOM, pick-and-place data, and a firmware package for JLCPCB assembly and flashing.
The hardware specification identifies a Nordic nRF52832 SoC with Bluetooth LE 4.2 as the smartwatch core.
Hackaday reports BLE and NFC alongside the low-power badge design, while the hardware archive identifies the nRF52832-based MDBT42Q module.
The repository includes apps and examples such as menu, REPL, Asteroids, Flappy Bird, Snake, Mario, T-Rex, sketch, and image-display code.
NodeWatch documents the Espruino embedded JavaScript interpreter and Bangle.js programming path as the watch's attendee-facing software platform.
The public source trail ties the badge to the Espruino/Puck.js JavaScript runtime lineage for attendee-programmable behavior.
The README says the badge is based on Pixl.js and uses Espruino IDE, CLI, and Pixl.js firmware-update workflows.
The badge exposed top LEDs, bottom LEDs, and a four-zone LCD backlight through pattern callbacks and `NC.ledTop`, `NC.ledBottom`, and `NC.backlight` APIs.
NodeWatch hardware specs list a 240x240 colour LCD, two-zone touch controller, GPS/Glonass receiver, accelerometer, compass, heart-rate sensor, flash, buzzer, and waterproof watch enclosure.
The public workshop repository gives attendees a hands-on Bangle.js development path for the NodeConf EU 2019 watch.
Operational history
The machine-learning feature is documented as an experimental constrained-device implementation rather than a broad general-purpose on-watch AI platform.
The dossier separates hardware, software, event, and challenge claims by source instead of treating one page as a complete archive.
The record treats NodeWatch as the NodeConf EU 2019 attendee badge without claiming exact batch size, every-ticket entitlement, or post-event availability limits.
The page avoids extrapolating a complete BOM, shipped firmware history, or production quantity beyond the recovered sources.
The record is included because the artifact matches the hackable conference badge scope, while the event classification stays explicit.
The dossier does not infer designer credit, attendee allocation, or production scale from the technical archive alone.
The record preserves practical attendee-facing limitations instead of presenting the badge as frictionless hardware.
The catalogue records the documented electronic CTF platform without inventing a universal configuration, quantity, delivery outcome, or attendee credential role.
Hardware and software claims stay limited to the README, schematic directory, and JavaScript source tree.
The public badge page, image archive, and API point at an exact upstream raster source with source URL, license, attribution, and processing notes while avoiding generated, placeholder, article, or uncleared imagery.
The NodeConf EU 2019 page remains source-backed and image-free instead of publishing an unclear or synthetic watch image.
The record is an event-linked maker badge and must not be read as a WICC organizer-issued credential, sponsor deliverable, official hardware programme, or attendee-wide handout.
The Ireland record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The dossier remains source-backed and image-free rather than copying repository PDF media, event graphics, or organizer social imagery without complete provenance.
The Irish 2018 record remains source-backed and image-free rather than copying badge-site or repository imagery without full provenance.
Primary claims come from the repository and README rather than relying on the expired-certificate homepage for evidence or images.
Software-resource links are preserved, but this record does not convert repository assets into local image or complete hardware-license claims.
The archive remains a valuable technical source, but it is not treated as permission to republish badge imagery or assume a universal source-license grant.
The record preserves related physical-hardware context without merging separate maker provenance, hardware counts, designs, allocations, or authorship into one unsupported badge claim.
