The Camp Badge

Cyber Saiyan community has designed and developed a special gadget to celebrate RomHack Camp 2022, The Badge.

You can grab The Badge by purchasing it at the Cyber Saiyan tent at the cost of 30€ (no remote purchasing, only people that will attend the Camp and the Conference can purchase it)

  • The badge’s package will include a lanyard, two batteries and…the badge
  • In order to start playing around with it and hacking it, is recommended to bring a micro USB data cable with you
  • It is also recommended to bring replacement 1.5V AA batteries and/or a powerbank
  • The badge is already flashed with the Cyber Saiyan firmware
  • We really will appreciate any improvement to the project and pull requests to the dedicated GitHub project page
  • Don’t hesitate to come and visit us at the Cyber Saiyan tent if you need help


The Badge has some very simple features that will improve your Camp experience:

  • It is designed to recall the dragon spheres (maybe you will be able to summon Shenron too)
  • The base SOC is a single core ESP32-C3
    • Integrates a 32-bit core RISC-V microcontroller with a maximum clock speed of 160 MHz
    • 22 configurable GPIOs
    • 400 KB of internal RAM and 4MB flash

  • In the front there are 7 RGB leds
  • In the back you will have two push buttons
    • Use your nail for a better experience 🙂
