LCA2021 SwagBadge

linux.conf.au 2021's Open Hardware Miniconf is represented by a source-backed SwagBadge and DagBadge programme: badges were built and mailed to delegates, then covered by official software, hardware, SAO, test-jig, firmware, and show-and-tell sessions.

Operational history

Issues & Camp Impact

LCA2021 SwagBadge note

hardware archive gap · source-backed but incomplete · needs stable public hardware archive

Official LCA2021 pages document SwagBadge/DagBadge hardware, firmware, SAOs, MicroPython/Aiko software, and tested shipped badges, but this pass did not recover a stable schematic, BOM, Gerber, PCB, firmware-source, or license archive.

The entry describes the public conference-badge programme and keeps component-level claims limited to sourced high-level evidence.

LCA2021 SwagBadge note

missing rights-cleared image · local project policy · needs licensed original replacement

No LCA2021 SwagBadge image is published because no reusable original badge photo or official upstream raster render with complete source URL, license, attribution, and processing notes has been recovered.

The record remains image-free rather than copying conference images, speaker photos, newsletter imagery, or generated art.
