BSides Perth 2025 ESP32 TFT Badge
Attendee-assembled ESP32 DevKit / 1.8-inch TFT challenge badge
The public BSides Perth 2025 badge archive and its assembly documentation identify a physical, attendee-assembled custom-PCB artifact built around an ESP32 DOIT DevKit v1, 1.8-inch LCD TFT, four tactile buttons, headers, and Micro-USB power.

The Shattered Shard (DEF CON 34)
Public player-guide electronic challenge badge; allocation unverified
BigDawgDave's public GitHub repository describes itself as the public repository for a DEF CON 34 RM-Cyber challenge badge called The Shattered Shard. Its Player Guide tells participants to use an assigned badge with a charged battery, a local Wi-Fi/browser interaction, a data-capable USB cable, a serial terminal, and one labelled-jumper task. It is enough evidence to preserve a separately named, independently documented pre-event electronic challenge badge, but it does not prove the RM-Cyber relationship, organizer authorization, hardware provenance, sale or giveaway, run size, allocation, physical handoff, completed on-site use, admission function, or a rights-cleared image.
