Description
The project identifies as "Your Raspberry Pi FM network". It uses a fork of the well-known PiFmRds as a backend to stream audio on FM radio. It allows the control of multiple pi units with a central server, that can also be temporarly hosted on google cloud shell or github codespaces.

Could you build this?
Partial The web coordination server and remote orchestration script are simple to vibe-code, but the core broadcast relies on specialized low-level hardware control over the Raspberry Pi's GPIO clock generator.
What it would actually take: The solution pairs a lightweight web orchestration dashboard (Node.js/Python) with a daemon running on Raspberry Pis that drives DMA (Direct Memory Access) and the PWM/PCM clock generators (via PiFmRds) to modulate RF on GPIO 4. The hard part is low-level Linux hardware registers, DMA memory mapping, and handling RF interference and harmonics, though leveraging the existing open-source PiFmRds C binary drastically reduces the software burden to standard process management.
Discussion
17 comments analyzed.
Competitors mentioned: Professional DAB radio setups, Commercial single frequency networks, Car FM transmitters, WebRTC-based audio sync solutions
Concerns raised: Operating is illegal without RF license in most countries, Harmful harmonics polluting emergency services frequencies, Output power exceeds FCC low-power FM exemption limits, Easy to trace and subject to regulatory enforcement, Raspberry Pi GPIO generates dirty square waves unsuitable for RF
Feature requests: Bandpass filter specifications and wiring instructions, Shielded transmission line requirement in documentation, Stronger legal/regulatory warnings in README, Guidance on sample-accurate playback timing, Better sync mechanism than multiple FM transmitters
