GopherBadge
Learn. Create. Invent.
A hackable conference badge and educational platform built on the Raspberry Pi RP2040. Programme it in Go with TinyGo, experiment with sensors and LEDs, and carry the open hardware spirit wherever you go.
Gopher Badge is designed to be an educational tool for learning about electronics and programming, as well as a platform for building projects and prototypes. It features a Raspberry Pi RP2040 microcontroller — a powerful and flexible chip suited for a wide range of applications — together with a variety of sensors, LEDs, and other components for experimentation and learning.
In addition to being a learning tool, the Gopher Badge is a very cool conference badge. It can be programmed to display custom animations, provide real-time data, and even interact with the environment. Its small size and low power consumption make it easy to wear for the duration of a conference, and the ability to programme it with a variety of languages makes it accessible to a wide range of attendees.
The Gopher Badge is only possible thanks to the help and effort of Purple Hardware by Pólux, who helped during the designing, building and testing process.
