Notes
Restored from the retained rights-cleared source bornhack-2023-github-badges-front-cc-by-sa-4.jpg. Retained the complete original frame and background. 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. The source shows two upright badge PCBs. 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.

People

Attribution Gap

No public individual author, designer, firmware, or team credits have been seeded for this badge yet. Add named credits only when a primary badge-team page, repository, talk, or other source identifies the people or team behind the work.

Why It Mattered

The 2023 badges made NFC itself the badge-hacking subject, with both passive/tag-style and active reader/card-emulation hardware in the camp ecosystem.

Hardware

Reader badge with RP2040, 16 MB Quad SPI flash, NXP PN7150 NFC controller, USB-C, and tag badge based on NXP NTAG I2C Plus.

Software & Apps

CircuitPython preloaded on the reader badge, UF2 restore path, dedicated CircuitPython branch, and an initial Python NFC demonstration branch.

Lore

The README explicitly invites campers to submit projects running on the badge, leaving the repository as a living post-camp project list.
