People
The official badge page states that Cyber Saiyan designed and developed the RomHack Camp 2022 badge.
SourceRomHack'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.
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.
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.
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.
Lifecycle
The firmware exposed schedule viewing plus AP and schedule-sync modes so attendees could update and interact with camp data from the badge.

SourceCyber Saiyan reused the RHC22 badge as a MOCA 2024 workshop and contest target, publishing a dedicated firmware branch and inviting owners to bring the badge, a PC, and USB cable.

SourceOperational history
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.
