Kilkenny · Ireland · 2017
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.
Lifecycle
Hackaday reports a Konami-code sequence, hidden behavior, and a Grand Challenge for hacked badges during the event.
The repository hardware directory exposes Eagle schematic and board files plus exported PDFs for the badge design.
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.
The public source trail ties the badge to the Espruino/Puck.js JavaScript runtime lineage for attendee-programmable behavior.
Operational history
The dossier separates hardware, software, event, and challenge claims by source instead of treating one page as a complete archive.
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 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.
