Program and build RPi-based ham station utilities, tools, and instruments Although much classical HF and mobile equipment is still in use by many amateurs, the use of computers and digital techniques has now become very popular among amateur radio operators. Nowadays, anyone can purchase a Raspberry Pi computer and run almost all amateur radio software on the ‘RPi’, which is slightly bigger than the size of a credit card. The RTL-SDR devices have become very popular among hams 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, an RPi computer, a USB-based external audio input-output adapter, and software installed on the Pi. With such a simple setup it is feasible to receive signals from around 24 MHz to over 1.7 GHz. With the addition of a low-cost upconverter device, an RTL-SDR can easily and effectively receive the HF bands. This book is aimed at amateur radio enthusiasts, electronic engineering students, and anyone interested in learning to use the Raspberry Pi to build electronic projects. The book is suitable for the full range of beginners through old hands at ham radio. Step-by-step installation of the operating system is described with many details on the commonly used Linux commands. Some knowledge of the Python programming language is required to understand and modify the projects given in the book. Example projects developed in the book include a station clock, waveform generation, transistor amplifier design, active filter design, Morse code exerciser, frequency counter, RF meter, and more. The block diagram, circuit diagram, and complete Python program listings are given for each project, including the full description of the projects. Besides wide coverage of RTL-SDR for amateur radio, the book also summarizes the installation and use instructions of the following ham radio programs and software tools you can run on your Raspberry Pi: TWCLOCK, Klog, Gpredict, FLDIGI, DIRE WOLF, xcwcp, QSSTV, LinPsk, Ham Clock, CHIRP, xastir, and CQRLOG.

Most people are increasingly confronted with the applications of Artificial Intelligence (AI). Music or video ratings, navigation systems, shopping advice, etc. are based on methods that can be attributed to this field. The term Artificial Intelligence was coined in 1956 at an international conference known as the Dartmouth Summer Research Project. One basic approach was to model the functioning of the human brain and to construct advanced computer systems based on this. Soon it should be clear how the human mind works. Transferring it to a machine was considered only a small step. This notion proved to be a bit too optimistic. Nevertheless, the progress of modern AI, or rather its subspecialty called Machine Learning (ML), can no longer be denied. In this book, several different systems will be used to get to know the methods of machine learning in more detail. In addition to the PC, both the Raspberry Pi and the Maixduino will demonstrate their capabilities in the individual projects. In addition to applications such as object and facial recognition, practical systems such as bottle detectors, person counters, or a “talking eye” will also be created. The latter is capable of acoustically describing objects or faces that are detected automatically. For example, if a vehicle is in the field of view of the connected camera, the information 'I see a car!' is output via electronically generated speech. Such devices are highly interesting examples of how, for example, blind or severely visually impaired people can also benefit from AI systems.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

A Handbook on DIY Nowadays, security problems are rarely properly solved or correctly addressed. Electronic security is only part of the chain in making a system secure. Electronic security is usually addressed as network or software security, neglecting other aspects, but the chain is only as strong as its weakest link. This book is about electronic hardware security, with an emphasis on problems that you can solve on a shoestring DIY budget. It deals mostly with secure communications, cryptosystems, and espionage. You will quickly appreciate that you can’t simply buy a trustworthy and reliable cryptosystem off the shelf. You will then realise that this applies equally to individuals, corporations, and governments. If you want to increase your electronic security awareness in a world already overcrowded with networks of microphones and cameras, this is a book for you. Furthermore, if you want to do something DIY by designing and expanding upon simple electronic systems, please continue reading. Some of the devices described are already published as projects in the Elektor magazine. Some are still ideas yet to be worked out. Complexity is the main enemy of security, so we'll try to keep to simple systems. Every chapter will analyse real-life espionage events or at least several hypothetical scenarios that will hopefully spark your imagination. The final goal is to build a security-conscious mindset (or “to get into a head of a spy”) which is necessary to recognise possible threats beforehand, to design a truly secure system. Don’t bother reading if: you think you and your secrets are 100% safe and secure you think somebody else can effectively handle your security you think conspiracy theories only exist in theory – Telefunken’s masterpiece the “FS-5000 Harpoon” was built on one!

Zowel desktop- als webgebaseerde toepassingen komen aan bod.De gebruikte programmeertaal is Python 3, een van de populairste talen die er zijn: snelheid van programmeren is een belangrijk kenmerk. Het boek is herzien en bijgewerkt met de nadruk op de gebruiker om praktische ontwerpen met gemak te produceren – een teksteditor is alles wat nodig is om Python-programma's te produceren.Hardware interfacing wordt bereikt met behulp van een Arduino Uno als een remote slave. Een volledige beschrijving en broncode van de communicatie-interface wordt gegeven in het boek. De slave biedt digitale en analoge in- en uitgangen. Meerdere Uno's kunnen in een project worden opgenomen met alle besturingscode geschreven in Python en draaiend op een PC Een project omvat een PIC microcontroller met de code die in de PIC kan worden geladen met behulp van de Uno.De webapplicaties en server zijn allemaal in Python geïmplementeerd, zodat u via internet toegang hebt tot uw elektronische hardware. De Raspberry Pi computer kan worden gebruikt als uw webserver. Er is een inleidend hoofdstuk om u op weg te helpen met het gebruik van Linux.Het boek is geschreven voor gebruik met Debian of variaties daarop, waaronder Mint of Ubuntu.
