SAINTCON 2025 Wrench Badge
Oversized ESP32-S3 wrench badge with an NFC tag, a six-faction game, and Nut game stations
The SAINTCON 2025 main badge for the October 21-24, 2025 conference in Provo, shaped as what its designer calls a comically oversized wrench: a 50 mm wrench with a 10 mm lanyard hole. An NFC tag in the jaw collected one-time codes from NFC game stations called Nuts, and the badge checked those codes in with a game server to score points or unlock game nodes. compukidmike published the schematic, BOM, Gerbers, KiCad files, and ESP-IDF firmware for the badge and the Nuts on October 27, 2025. The archived official BadgeLife page frames the badge game as the conclusion of the Klippy AI storyline begun in 2023.
