HackConRD 2026 eBadge

ESP32-C3, CC1101, TFT, games, and RF badge

HackConRD 2026's eBadge was documented by the official HackConRD site, the EBADGE+ ticket tier, the interactive eBadge page, and a public firmware repository that describes an ESP32-C3 badge with ST7789 TFT, CC1101 433 MHz radio, WS2812B LEDs, buzzer, four-button navigation, games, RF friend exchange, fox hunting, learning modules, and persistent profile settings.

Why It Mattered

It deepens the Caribbean entry from a first badge into a richer event-computer record, with official ticket evidence and public firmware rather than only social media or gallery photos.

Hardware

The public repository README documents an ESP32-C3 RISC-V MCU, Adafruit ST7789 240x240 RGB565 TFT, CC1101 radio at 433 MHz sharing SPI with the display, twelve WS2812B LEDs, passive buzzer, and four buttons for up, down, back, and OK. The official eBadge page describes Sub-GHz handshake behavior and CC1101 learning content, while the official site lists the EBADGE+ tier with lanyard and electronic badge.

Software & Apps

The firmware README describes an Arduino ESP32-C3 project with Adafruit GFX/ST7789, FastLED, QRCodeGenerator, Preferences/NVS, game modules for Doom Maze, Dino Run, Hackermon, and Star Invaders, RF Fox Hunting with RSSI, Friends RF peer-to-peer profile exchange, educational modules, nickname and badge-role profile storage, screensaver image assets, LED themes, brightness settings, and persistent NVS keys.

Lore

The official HackConRD 2026 page frames the event as the Dominican Republic's hacker conference by RedTeamRD and includes an eBadge showcase link, post-event gallery/recap context, sponsors, and Hotel Dominican Fiesta reservation context.

Issues & Camp Impact

hardware-source depth caveat note

The recovered 2026 trail documents controller, display, radio, LEDs, buzzer, buttons, firmware, games, RF behavior, and ticket inclusion, but this pass did not recover schematic, PCB files, BOM, enclosure files, exact shipped quantity, or hardware errata.

The record keeps hardware claims to the official site and firmware repository without inventing a final circuit, board revision, manufacturing run, or image provenance.

Confidence: firmware/readme source but no CAD archive
Status: needs hardware archive recovery
Timeframe: HackConRD 2026
Source note: HackConRD 2026 site, eBadge page, and Badge_HackConRD_2026 README.

missing rights-cleared image note

No HackConRD 2026 eBadge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

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.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and HackConRD 2026 official site, eBadge page, EBADGE+ ticket tier, and public Badge_HackConRD_2026 firmware repository.

repository-license caveat note

GitHub reports no detected license for `w0rkm4n/Badge_HackConRD_2026`, and the official site footer reserves rights.

The firmware repository and official pages are used as evidence, but site photos, animated renders, frames, YouTube thumbnails, and repository images are not copied as catalogue visuals.

Confidence: GitHub metadata
Status: documented for source only
Timeframe: current catalogue build
Source note: HackConRD official pages, GitHub repository metadata, and badge.gallery image policy.
