NorthSec 2026 Badge
Official ESP32-S3 NFC e-paper badge with post-event Apache-2.0 source release
NorthSec 2026's official registration page lists a new social electronic badge as an included item for conference, CTF, combo, and training ticket holders while supplies lasted. The official competition page's retained 2026 Solarpunk section says the hackable electronic badge was fully integrated into the CTF, with badge challenges worth points and on-site badge-firmware tampering among the physical tracks. Official villages pages document badge pickup through attendees' nSec order QR codes, soldering-village activity where attendees could enhance their badge with blinking electronic parts, and a badge museum. On August 3, after the May event, NorthSec published the separate Apache-2.0 `nsec/badge-2026` repository. Its commit-pinned hardware and source tree documents an ESP32-S3 badge design with an ST25R3916 NFC front end, six buttons, eighteen WS2812/NeoPixel LEDs, a 200×200 GDEH0154D67 / SSD1681 e-paper path, KiCad design files, production BOM/CPL/Gerbers, PlatformIO firmware, conference/CTF partitions, CTF assets, and dock/SAO directories.
