Hackers Teaching Hackers 2026 Eagle 5 Badge
nRF52840/SX1262 electronic conference badge with a public post-event GPL firmware archive
Hackers Teaching Hackers' official materials establish the June 3-5, 2026 Columbus-area practitioner conference with villages and a CTF. Zack Nagaich's public Eagle 5 repository labels itself the 2026 HTH conference-badge firmware and documents an nRF52840 plus SX1262 electronic badge with LEDs, USB roles, RNode/Reticulum-oriented firmware, on-badge CLI, and CTF source context. An attendee account independently says their light-up badge was part of the conference CTF, while the organizer has not directly published this 2026 repository or a distribution record.
