Operational history

Issues & Camp Impact

LCA2022 SwagBadge and Rockling SAO Kit note

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

Official LCA2022 pages document hardware kits, an updated SwagBadge, FPGA SAOs, Rockling and SAO sessions, and a hardware-design talk, but this pass did not recover a stable schematic, BOM, bitstream, firmware, PCB, or repository license archive.

The entry captures the event-backed kit and badge lineage while avoiding unsupported chip-part, board-revision, firmware, or shipped-behavior claims.

LCA2022 SwagBadge and Rockling SAO Kit note

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

No LCA2022 SwagBadge, Rockling, or SAO image is published because no rights-cleared original photo or official upstream raster render with complete provenance has been recovered.

The record stays image-free rather than copying event imagery, talk thumbnails, or generated badge art.
