Las Vegas Convention Center, Las Vegas, Nevada · United States · 2025
Lonely Hackers Club's Meshtastic Badge 2025 was a limited 50-unit community badge offered for DEF CON 33 pickup, built around a Heltec Wireless Tracker V1.1 LoRa radio board, preconfigured LHC channel behavior, and attendee pairing workflows.
Lifecycle
The official page describes pairing with other LHC badges, after which the badge reveals a QR code on the Meshtastic channel.
The badge page states that only 50 units were available, shipping was not offered, and pickup was at DEF CON 33 with possible in-person sales if any were left.
The official page lists Heltec Wireless Tracker V1.1 hardware with ESP32-S3FN8, SX1262 915 MHz LoRa, UC6580 GPS, TFT display, user button, RGB LED, buzzer, and 450 mAh battery.
The badge ships with the LHC channel preprogrammed, while the LHC guide documents QR-code onboarding and Meshtastic channel setup.
The page says the badge can be used as a normal Meshtastic node after the event, keeping the artifact useful beyond DEF CON 33.
Operational history
The catalogue treats it as an unofficial/community DEF CON 33 badge release, separate from the mainline DEF CON 33 badge and village-issued badges.
The record preserves the limited-run status without overclaiming final distribution.
The catalogue records verified hardware and firmware configuration while avoiding unsupported custom-board or source-release claims.
The record remains source-backed and image-free rather than copying product photos, site graphics, forum media, screenshots, or generated imagery without complete provenance.
