redsea - A lightweight RDS to JSON decoder

  •        99

redsea is a lightweight command-line FM-RDS decoder for Linux/macOS, written by Oona Räisänen. It can be used with any RTL-SDR USB radio stick with the rtl_fm tool. It can also decode raw ASCII bitstream, the hex format used by RDS Spy, and audio files containing multiplex signals (MPX). Decoded RDS groups are printed to the terminal as line-delimited JSON objects or, optionally, undecoded hex blocks (-x). Please refer to the wiki for JSON field descriptions and input data formats.

rtlamr - An rtl-sdr receiver for Itron ERT compatible smart meters operating in the 900MHz ISM band.

  •    Go

Utilities often use "smart meters" to optimize their residential meter reading infrastructure. Smart meters transmit consumption information in the various ISM bands allowing utilities to simply send readers driving through neighborhoods to collect commodity consumption information. One protocol in particular: Encoder Receiver Transmitter by Itron is fairly straight forward to decode and operates in the 900MHz ISM band, well within the tunable range of inexpensive rtl-sdr dongles. This project is a software defined radio receiver for these messages. We make use of an inexpensive rtl-sdr dongle to allow users to non-invasively record and analyze the commodity consumption of their household.

rtl-entropy - An entropy generator using SDR peripherals, including rtl-sdr and BladeRF

  •    C

rtl-entropy is software using rtl-sdr to turn your DVB-T dongle into a high quality entropy source. It samples atmospheric noise, does Von-Neumann debiasing, runs it through the FIPS 140-2 tests, then optionally (-e) does Kaminsky debiasing if it passes the FIPS tests, then writes to the output. It can be run as a Daemon which by default writes to a FIFO, which can be read by rngd to add entropy to the system pool. If you're serious about the cryptographic security of your entropy source, you should probably short, or put a 75 Ohm load on the antenna port, and put the whole assembly in a shielded box. Then you're getting entropy from the thermal noise of the amplifiers which is much harder to interfere with than atmospheric radio.

Raspberry-Pi - Raspberry Pi A to Z List


Raspberry Pi A to Z List Basics Raspberry Pi The Raspberry Pi was originally designed for educational purposes to use in schools and universities, and to make class and study more interesting. Unfortunately, the practical use of the Raspberry Pi or a comparable single-board computer in Germany, Austria and Switzerland is still in its infancy. Listening to the topic, you will find only a few examples showing the use of the Raspberry Pi in school, in education or in study. The following tasks and exercises should help a little here. They are suitable for self-study or as a source for teachers and faculty to build their own Raspberry Pi workshop. The tasks also include exemplary ready-made solutions. 1. Getting Started: Tasks and Exercises with Raspberry Pi The following tasks and exercises are suitable for beginners who have not yet come into contact with the Raspberry Pi. The solutions are also interesting for those who already know the Raspberry Pi and have worked with it. The solutions are part of standard tasks that have to be done around the Raspberry Pi every now and then.

serial-port-json-server - A serial port JSON websocket server for Windows, Mac, Linux, Raspberry Pi, or BeagleBone Black that lets you communicate with your serial port from a web application

  •    Go

A serial port JSON websocket & web server that runs from the command line on Windows, Mac, Linux, Raspberry Pi, or Beagle Bone that lets you communicate with your serial port from a web application. This enables web apps to be written that can communicate with your local serial device such as an Arduino, CNC controller, or any device that communicates over the serial port. Since version 1.82 you can now also program your Arduino by uploading a hex file. The app is written in Go. It has an embedded web server and websocket server. The server runs on the standard port of localhost:8989. You can connect to it locally with your browser to interact by visiting http://localhost:8989. The websocket is technically running at ws://localhost/ws. You can of course connect to your websocket from any other computer to bind in remotely. For example, just connect to ws:// if you are on a remote host where is your devices actual IP address.

raspberry-pi-os - Learning operating system development using Linux kernel and Raspberry Pi

  •    C

This repository contains a step-by-step guide that teaches how to create a simple operating system (OS) kernel from scratch. I call this OS Raspberry Pi OS or just RPi OS. The RPi OS source code is largely based on Linux kernel, but the OS has very limited functionality and supports only Raspberry PI 3. Each lesson is designed in such a way that it first explains how some kernel feature is implemented in the RPi OS, and then it tries to demonstrate how the same functionality works in the Linux kernel. Each lesson has a corresponding folder in the src directory, which contains a snapshot of the OS source code at the time when the lesson had just been completed. This allows the introduction of new concepts gracefully and helps readers to follow the evolution of the RPi OS. Understanding this guide doesn't require any specific OS development skills.

raspap-webgui - A simple, responsive web interface to control wifi and hostapd on the Raspberry Pi

  •    PHP

A simple, responsive web interface to control wifi, hostapd and related services on the Raspberry Pi. This project was inspired by a blog post by SirLagz about using a web page rather than ssh to configure wifi and hostapd settings on the Raspberry Pi. I mostly just prettified the UI by wrapping it in SB Admin 2, a Bootstrap based admin theme. Since then, the project has evolved to include greater control over many aspects of a networked RPi, better security, authentication, a Quick Installer, support for themes and more. RaspAP has been featured on sites such as Instructables, Adafruit, Raspberry Pi Weekly and Awesome Raspberry Pi and implemented in countless projects.

pi-apps - Raspberry Pi App Store for Open Source Projects
