Группа выше: Радиолюбительство и радиоприём
Смысл: The main idea is to demonstrate a creative and accessible way to perform spectrum painting by using standard computer audio hardware and a simple RF mixer instead of specialized SDR transmitters, proving that basic physics and signal processing can achieve visual data transmission over radio frequencies.
The author demonstrates how to transmit images and low-resolution video onto an SDR spectrogram using a computer's audio output and a simple RF mixer.
Смысл: The main idea is that a Raspberry Pi can be easily converted into an FM radio transmitter using a simple Python library and a short piece of wire as an antenna.
A brief guide on how to transform a Raspberry Pi into an FM transmitter using the PiFm library and a 20cm wire.
Смысл: The text is a technical guide and personal experiment on how to bridge analog radio transmissions to an online streaming service using affordable hardware and cloud servers.
A hobbyist explains how to stream local radio transmissions (like police and taxi) to the web using a Puxing radio, SAM Broadcaster, and an AWS-hosted Icecast server.
Смысл: The text is a technical memoir and guide about the long-term development of a DIY internet radio, emphasizing the intersection of modern Linux-based computing and retro hardware aesthetics.
An engineer documents the 12-year process of building a custom Wi-Fi radio using a BeagleBone Black, an Arduino controller, and a vintage VFD customer display.
