BotWave

What it does

BotWave transforms Raspberry Pi devices into a network-based FM broadcasting system. Unlike single-device FM projects, BotWave uses server-client architecture to manage multiple Pi transmitters from one central location. Single-device use is still supported. Key features: remote control, one-line installation, live streaming support, and file management across your network. Perfect for learning radio broadcasting, campus radio networks, and experimentation. GPLv3 licensed.

Broadcast audio files over FM radio using Raspberry Pi devices. Server-client architecture for managing multiple Pi clients remotely.

BotWave lets you broadcast audio over FM radio using cheap Raspberry Pi devices. It supports both single-device setups and multi-Pi networks, with features like remote control, live streaming, automated actions, and more, making it great for learning, experimentation, and creative projects. curl -sSL botwave.dpip.lol/install | sudo bash botwave Detailed setup instructions ↗ ² Source Code View the project onfrom botwave.dpip.lol

  An easy way of broadcasting radio around you (looking for feedback)Dec 2025 · github.com · ▲36

  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.

  PIrateRF – Turn a $20 Raspberry Pi Zero into a 12-mode RF transmitterFeb 2026 · github.com · ▲33

  I built a software-defined radio transmission platform that runs on a Raspberry Pi Zero W. It spawns its own WiFi hotspot and serves a web UI — connect from any device and you have a portable RF signal generator with 12 transmission modes: FM broadcasting with RDS, FT8, RTTY, FSK, POCSAG paging, Morse code, SSTV image transmission, voice cloning via live mic, spectrum painting, IQ replay, carrier wave, and frequency sweeps. Everything runs through a browser interface. Upload audio files, type messages, configure frequencies, and transmit. The Pi's GPIO pin does the actual RF generation via…

  A few months ago, I was inspired by this post on Reddit, titled: Food items should have QR codes that instruct the microwave exactly what to do. Like high for 2 minutes, let stand 1 minute, medium 1 minutes.. I thought this was a pretty cool idea, and that it

  Multi-room audio with Snapcast and Raspberry Pi2020 · oyvn.github.io · ▲215

  Snapcast is an open-source project that streams audio over network so it can be played synchronously, like Sonos. I recently set it up at home with some Raspberry Pis to play Spotify around my apartment. Here’s how I did it. I tried to show my work, so hopefully people can follow along (I’m no Raspb

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
