Why It Mattered

It shows Badge.Team hardware being reused across smaller European events instead of living only as one-off camp productions.

Hardware

Badge.Team documents extra PSRAM, IR transmitter/receiver, stereo audio output, Grove I2C connector, and SAO connector.

Software & Apps

Built from the SHA2017/Badge.Team lineage, with documentation focused on hardware differences and event-specific use.

Lore

The official page records an audio-jack design error and the field fix, preserving the badge's production reality instead of just the polished spec.

Lifecycle

Add-ons & Upgrades

Operational history

Issues & Camp Impact

hardware errata moderate

The audio jack was mounted in reverse due to a design error, requiring the first and third rings to be swapped for correct stereo output.

Attendees needed a hardware fix for proper audio behavior.

missing rights-cleared image note

No HackerHotel 2019 badge image is published because the current Badge.Team source trail has not been paired with a reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The record remains source-backed and image-free rather than copying Badge.Team page media, documentation screenshots, event photos, placeholders, or generated approximations.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and HackerHotel 2019 Badge.Team docs.
