HackConRD 2024's first official badge was an ATTiny85-based electronic conference badge documented by a public repository and workshop writeup, with lanyard wear, challenge/hidden-feature firmware, serial reprogramming, aRGB LED expansion, buzzer output, and KiCad manufacturing-file evidence.
Lifecycle
The README says physical pin 2 controls badge aRGB LEDs and external LED expansion pads, while physical pin 3 controls the built-in buzzer.
The badge-team writeup says HackConRD used the conference logo for the first iteration of its official badge, marking the beginning of Badgelife in the HackConRD community.
The documentation maps serial-interface pins and reset-button timing for uploading Arduino IDE code to the badge.
The public repository preserves a KiCad schematic, BOM, placement CSV, and fabrication ZIP for the 2024 badge.
The README identifies ATTiny85 / ATTiny45/85 Optiboot as the badge controller target and documents Arduino IDE / ATTinyCore setup.
Operational history
The record states first official badge and technical archive details without claiming attendee-wide distribution mechanics or quantity.
The Dominican Republic record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The catalogue cites the repository as evidence for the 2024 badge but does not copy its render, photos, pinout images, screenshots, notebook media, or fabrication archive media into the public image directory.
