This is the second edition of a book aimed at engineers, scientists, and hobbyists who want to interface PCs with hardware projects using graphical user interfaces. Desktop and web-based applications are covered. The programming language used is Python 3, which is one of the most popular languages around: speed of programming being a key feature. The book has been revised and updated with an emphasis on getting the user to produce practical designs with ease – a text editor is all that is required to produce Python programs. Hardware interfacing is achieved using an Arduino Uno as a remote slave. A full description and source code of the communication interface is given in the book. The slave provides digital and analog input and outputs. Multiple Unos can be included in one project with all control code written in Python and running on a PC One project involves a PIC microcontroller with the code provided that can be loaded into the PIC using the Uno. The web applications and server are all implemented in Python, allowing you to access your electronic hardware over the Internet. The Raspberry Pi computer can be used as your web server. An introductory chapter is provided to get you started with using Linux. The book is written for use with Debian or variations including Mint or Ubuntu. All of the programs in the book are freely available, ready to use and experiment with by way of a download from Elektor.

Learn programming for Alexa devices, extend it to smart home devices and control the Raspberry Pi The book is split into two parts: the first part covers creating Alexa skills and the second part, designing Internet of Things and Smart Home devices using a Raspberry Pi. The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed. In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language. The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi. Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated. Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color. A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi. A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device. The book concludes by explaining how to create Raspberry Pi as a stand-alone Alexa device.

The SDRplay RSPdx-R2 is a wideband full featured single-tuner 14-bit SDR receiver which covers the entire RF spectrum from 1 kHz to 2 GHz giving up to 10 MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200 MHz. The RSPdx-R2 is an enhanced version of the RSPdx with further design improvements for use at frequencies below 2 MHz. Housed in a strong steel case, in addition to the functionality of the RSP1B, the RSPdx-R2 provides three software selectable antenna inputs and an external clock input. It offers excellent performance through HF and VHF frequencies all the way up to 2 GHz. The RSPdx-R2 also supports an "HDR mode" optimised for the demanding radio reception conditions below 2 MHz. The RSPdx-R2, when used in conjunction with SDRplay’s own software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2 MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. Features Covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps Receive, monitor and record up to 10 MHz of spectrum at a time Significantly improved noise performance below 1 MHz (i.e. for some MF, LF and below) Improved dynamic range below 2 MHz both in tuner mode and HDR mode HDR mode below 2 MHz giving overall dynamic range and selectivity advantages Software selectable choice of 3 antenna ports External clock input for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy Excellent dynamic range for challenging reception conditions Free use of Windows-based SDRuno software (check website for versions supported) Free use of SDRconnect SDR and server software for Windows, MacOS and Linux (Check website for versions supported) Multiplatform driver and API support including Windows, Linux, Mac and Raspberry Pi 4/5 Strong and growing software support network Calibrated S meter/RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability) Documented API provided to allow demodulator or application development on multiple platforms Applications (Amateur) Shortwave radio listening Broadcast DXing (AM/FM/TV) Panadaptor Aircraft (ADS-B and ATC) Slow Scan TV Multi-amateur band monitoring WSPR & digital modes Weather fax (HF and satellite) Satellite monitoring Geostationary environmental satellites Trunked radio Utility and emergency service monitoring Fast and effective antenna comparison Applications (Industrial) Spectrum Analyser Surveillance Wireless microphone monitoring RF surveying IoT receiver chain Signal logging RFI/EMC detection Broadcast integrity monitoring Spectrum monitoring Power measurement Applications (Educational/Scientific) Teaching Receiver design Radio astronomy Passive radar Ionosonde Spectrum analyser Receiver for IoT sensor projects Antenna research Specifications Frequency Range 1 kHz – 2 GHz Antenna Connector SMA Antenna Impedance 50 Ohms Current Consumption (Typical) 190 mA @ >60 MHz (excl.
