Project Overview

GuSi is an open-source minimalist DIY internet radio project created by a solo German developer, hosted on the developer's personal domain mneufeld.de. Built around the design philosophy of cutting out redundancy, returning to the core of listening, it targets electronics hobbyists who enjoy building projects from scratch, and is also well-suited for users less comfortable with complex operations like seniors and children. The project provides full free design files and assembly guides, so users can 3D-print their own enclosure and source all the components to build a custom internet radio by themselves.

Core Features

The project's key design highlight is that it does away with the traditional display and complex menus found on most radios. The entire process—from initial setup to station information updates—is handled via voice guidance, with only a few physical buttons kept for basic operation, which means accidental mis操作 is almost impossible. For network setup, it supports one-tap WPS connection, and can also set up via a built-in hotspot that lets you configure settings from your phone, no extra app installation required.

Three models with different use cases are currently available:

• The base model BM1K only has volume and station selection knobs, perfect for users who just want pure listening experience
• BM2K adds a pause function, ideal for everyday use
• RM5K features a retro exterior design, made for vintage style lovers

All enclosure files are available for free in STL format, compatible with standard desktop 3D printers. Assembly only requires basic tools like a screwdriver and soldering iron, the guide has clear step-by-step instructions, and no advanced programming skills are needed.

Target Audience & Accessibility

This website is currently directly accessible from mainland China, and all documentation is available for free download. It's a great project for electronics hobbyists who love DIY, and it's especially perfect for building a simple-to-operate internet radio for elderly family members.
The downside is that it only provides design plans, so you have to build it entirely from scratch yourself, and there's no Chinese documentation, which creates a bit of a barrier for casual users in China.
