World’s Most Popular ROS PlatformTurtleBot is the most popular open source robot for education and research. The new generation TurtleBot3 is a small, low cost, fully programmable, ROS based mobile robot. It is intended to be used for education, research, hobby and product prototyping.Affordable CostTurtleBot was developed to meet the cost-conscious needs of schools, laboratories and companies. TurtleBot3 is the most affordable robot among the SLAM-able mobile robots equipped with a 360° Laser Distance Sensor LDS-01.ROS StandardThe TurtleBot brand is managed by Open Robotics, which develops and maintains ROS. Nowadays, ROS has become the go-to platform for all the roboticists around the world. TurtleBot can be integrated with existing ROS-based robot components, but TurtleBot3 can be an affordable platform for whom want to get started learning ROS.ExtensibilityTurtleBot3 encourages users to customize its mechanical structure with some alternative options: open source embedded board (as a control board), computer and sensors. TurtleBot3 Waffle Pi is a two-wheeled differential drive type platform but it is able to be structurally and mechanically customized in many ways: Cars, Bikes, Trailers and so on. Extend your ideas beyond imagination with various SBC, sensors and motors on a scalable structure.Modular Actuator for Mobile RobotTurtleBot3 is able to get a precise spatial data by using 2 DYNAMIXEL’s in the wheel joints. DYNAMIXEL XM series can be operated by one of 6 operating modes (XL series: 4 operating modes): Velocity control mode for wheels, Torque control mode or Position control mode for joint, etc. DYNAMIXEL can be used even to make a mobile manipulator which is light but can be precisely controlled with velocity, torque and position control. DYNAMIXEL is a core component that makes TurtleBot3 perfect. It is easy to assemble, maintain, replace and reconfigure.Open Control Board for ROSThe control board is open-sourced in hardware wise and in software wise for ROS communication. The open source control board OpenCR1.0 is powerful enough to control not only DYNAMIXEL’s but also ROBOTIS sensors that are frequently being used for basic recognition tasks in cost effective way. Various sensors such as Touch sensor, Infrared sensor, Color sensor and a handful more are available. The OpenCR1.0 has an IMU sensor inside the board so that it can enhance precise control for countless applications. The board has 3.3 V, 5 V, 12 V power supplies to reinforce the available computer device lineups.Open SourceThe hardware, firmware and software of TurtleBot3 are open source which means that users are welcomed to download, modify and share source codes. All components of TurtleBot3 are manufactured with injection molded plastic to achieve low cost, however, the 3D CAD data is also available for 3D printing.Specifications

Program and Build Raspberry Pi 5 Based Ham Station Utilities with the RTL-SDR
The RTL-SDR devices (V3 and V4) have gained popularity among radio amateurs because of their very low cost and rich features. A basic system may consist of a USB based RTL-SDR device (dongle) with a suitable antenna, a Raspberry Pi 5 computer, a USB based external audio input-output adapter, and software installed on the Raspberry Pi 5 computer. With such a modest setup, it is possible to receive signals from around 24 MHz to over 1.7 GHz.
This book is aimed at amateur radio enthusiasts and electronic engineering students, as well as at anyone interested in learning to use the Raspberry Pi 5 to build electronic projects. The book is suitable for both beginners through experienced readers. Some knowledge of the Python programming language is required to understand and eventually modify the projects given in the book. A block diagram, a circuit diagram, and a complete Python program listing is given for each project, alongside a comprehensive description.
The following popular RTL-SDR programs are discussed in detail, aided by step-by-step installation guides for practical use on a Raspberry Pi 5:

The application of the Python programming language on the latest Raspberry Pi 5 platform precludes the use of the programs in the book from working on older versions of Raspberry Pi computers.
Wanneer u regelmatig experimenteert met de Raspberry Pi en verschillende externe hardware aansluit op de GPIO-poort via de header, heeft u mogelijk in het verleden schade veroorzaakt. Het Elektor Raspberry Pi Buffer Board is er om dit te voorkomen! Het board is compatibel met de Raspberry Pi Zero, Zero 2 (W), 3, 4, 5, 400 en 500.
Alle 26 GPIO's zijn gebufferd met bidirectionele spanningsomzetters om de Raspberry Pi te beschermen tijdens het experimenteren met nieuwe circuits. De printplaat is bedoeld om aan de achterkant van de Raspberry Pi 400/500 te worden geplaatst. De connector voor aansluiting op de Raspberry Pi is een haakse 40-polige connector (2x20). De printplaat is slechts iets breder. Een 40-polige flatcable met bijpassende 2x20 headers kan worden aangesloten op de buffer-uitgangsheader om bijvoorbeeld te experimenteren met een circuit op een breadboard of een printplaat.
Het circuit maakt gebruik van 4x TXS0108E IC's van Texas Instruments. De printplaat kan ook rechtop op een Raspberry Pi worden geplaatst.
