Badges
ESP32-C3 dragon-sphere camp badge
A Cyber Saiyan-designed ESP32-C3 badge for RomHack Camp 2022, with seven RGB LEDs, BLE badge discovery, schedule screens, WiFi/AP functions, snake, a 2.4 inch TFT, two rear buttons, and AA battery power.
ESP32-S3 Walkman-inspired handheld badge with Tactility, Retro-Go, and NFC TagQuest
The hardware badge of the October 2-4, 2026 RomHack Camp at Flaminio Village, whose event site and participant FAQ advertise a unique hardware badge and collectible challenge. On September 29-30, 2026, two days before the camp, Cyber Saiyan's official GitHub organization published the rhc2026-badge repository and the badge.romhack.io setup site: an ESP32-S3 handheld inspired by the Sony Walkman WM-22, with a 2.4-inch 320x240 ILI9341 screen, stereo audio and speaker, 22 RGB LEDs, a Ci522 13.56 MHz NFC reader, microSD, a LiPo battery, and USB-C, running a Tactility-based firmware with camp agenda, map, music player, a TagQuest NFC trivia hunt, and Retro-Go emulators. Firmware 0.4 was tagged on October 2, the camp's opening day. The camp has since ended (romhack.io: RomHack Camp 2026 is over; closing slides: 550 attendees), and the organizer README now opens with a Setup your badge link, but no source states how many badges were sold or handed out.
