AI Projects for the Raspberry Pi with the AI HAT+ Edge AI is transforming everyday devices by putting intelligence where it matters most: directly inside the hardware. With on-device inference, a camera can recognize a visitor instantly, a phone can translate speech without streaming audio to the cloud, and a wearable can detect anomalies in real time—fast, private, and reliable even when the network disappears. This book is your practical guide to building exactly those kinds of systems with the Raspberry Pi AI HAT+ and the Hailo-8L accelerator. You’ll start with clear foundations: core AI and machine-learning concepts, how neural networks work, and what truly distinguishes Edge AI from cloud AI—plus an honest look at ethical considerations and future impacts. Then it’s straight to hands-on physical computing. Step by step, you’ll set up Raspberry Pi OS, power and cooling, and develop in Python using the Thonny IDE. You’ll learn GPIO basics with lights and servos, mount the AI HAT+ hardware, install and verify the Hailo software stack, and connect the right camera—official modules or USB webcams, even multiple cameras. From your first pipeline to real projects, you’ll run person detection, pose estimation, segmentation, and depth estimation, then level up with YOLO object detection: smart alerts, guest counters, and custom extensions. You’ll even connect vision to motion by combining gesture recognition with servo-driven mechanisms, including a robotic arm. With troubleshooting tips, hardware essentials, and a practical Python refresher, this book turns Edge AI from buzzword into buildable reality.

Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems. In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible. In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers. Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power. A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.

Programming the Finite State Machine with 8-Bit PICs in Assembly and C Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information. This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer. A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly. Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming. Links Updated Programmer

As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more.

This book is for people who want to understand how AC drives (also known as inverter drives) work and how they are used in industry by showing mainly the practical design and application of drives. The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The different parts of an AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection. An important part of the book gives details of the features and functions often found in AC drives and gives practical advice on how and where to use these. Also described is future drive technology, including a matrix inverter. The mathematics is kept to an essential minimum. Some basic understanding of mechanical and electrical theory is presumed, and a basic knowledge of single andthree phase AC systems would be useful. Anyone who uses or installs drives, or is just interested in how these powerful electronic products operate and control modern industry, will find this book fascinating and informative.

Program, build, and master over 50 projects with MicroPython and the RP2040 microprocessor The Raspberry Pi Pico is a high-performance microcontroller module designed especially for physical computing. Microcontrollers differ from single-board computers, like the Raspberry Pi 4, in not having an operating system. The Raspberry Pi Pico can be programmed to run a single task very efficiently within real-time control and monitoring applications requiring speed. The ‘Pico’ as we call it, is based on the fast, efficient, and low-cost dual-core ARM Cortex-M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM, and 2 MB of Flash memory. Besides its large memory, the Pico has even more attractive features including a vast number of GPIO pins, and popular interface modules like ADC, SPI, I²C, UART, and PWM. To cap it all, the chip offers fast and accurate timing modules, a hardware debug interface, and an internal temperature sensor. The Raspberry Pi Pico is easily programmed using popular high-level languages such as MicroPython and or C/C++. This book is an introduction to using the Raspberry Pi Pico microcontroller in conjunction with the MicroPython programming language. The Thonny development environment (IDE) is used in all the projects described. There are over 50 working and tested projects in the book, covering the following topics: Installing the MicroPython on Raspberry Pi Pico using a Raspberry Pi or a PC Timer interrupts and external interrupts Analogue-to-digital converter (ADC) projects Using the internal temperature sensor and external temperature sensor chips Datalogging projects PWM, UART, I²C, and SPI projects Using Wi-Fi and apps to communicate with smartphones Using Bluetooth and apps to communicate with smartphones Digital-to-analogue converter (DAC) projects All projects given in the book have been fully tested and are working. Only basic programming and electronics experience is required to follow the projects. Brief descriptions, block diagrams, detailed circuit diagrams, and full MicroPython program listings are given for all projects described. Readers can find the program listings on the Elektor web page created to support the book.

Projects Using Arduino IDE and the LVGL Graphics Library The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays. The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches. All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.
