- Notes
- Restored from the retained rights-cleared source emfcamp-badges-wikimedia-rbirkby-cc0.jpg. Applied rectangular crop 1480x1050+120+990 (width x height + x + y, after auto-orientation), retaining the complete visible badge and surrounding original context. Auto-oriented, resized only when larger than a 1600px maximum side, metadata stripped, and encoded as WebP quality 82 with method 6, below 600 KiB. No local background masking, subject removal, invented pixels, or generative processing. Original lighting, hardware details, and photographed context are preserved. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Software & Apps
MicroPython, App Library, app submissions, USB copy workflows, firmware repos, server repo, and badge hacking workshop docs.
Lore
The wiki documents factory reset paths, app download problems, insecure camp WiFi caveats, and pinout corrections.
