Notes
Original 1218x1209 transparent upstream raster front render downloaded from the public CyberSaiyanIT/rhc22-badge repository, trimmed and resized for the site badge canvas while preserving transparency. The upstream repository is MIT licensed and also includes a rear render; this site asset uses the front render as the badge hero rather than a documentary field photo. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

Why It Mattered

RomHack's badge is a strong Italian camp record because it ties hardware hacking, camp schedule utility, BLE social discovery, and playful dragon-sphere lore into a first-camp artifact.

Hardware

The official badge page and README document an ESP32-C3 single-core RISC-V SoC at up to 160 MHz, 22 GPIOs, 400 KB internal RAM, 4 MB flash, WiFi, Bluetooth 5, seven front RGB LEDs, a 2.4 inch TFT display, two rear buttons, and a two-AA battery holder.

Software & Apps

The badge shipped with Cyber Saiyan firmware, advertised itself over BLE with a 1-7 ID, included schedule, badge radar, badge list, WiFi/AP and sync screens, and provided firmware/build instructions in the public GitHub repository.

Lore

The seven RGB LEDs deliberately recall dragon spheres; the badge-radar screen turns nearby BLE badges into a dragon-ball-style social hunt across the camp.

Issues & Camp Impact

field-kit dependency note

Badge hacking depended on attendee-supplied USB and battery power.

The official page recommended a micro USB data cable plus replacement AA batteries or a power bank, so a prepared kit mattered for camp hacking.
