A Small Basic Approach There are many different PC programming languages available on the market. Some have beautiful names; some have easy to use development tools. Others have incredible power. They all have one thing in common: they assume that you have, or want to have, a knack for technology and difficult to read commands. In this book we take a practical approach to programming. We assume that you simply want to write a PC program, and write it quickly. Not in a professional environment, not in order to start a new career, but for plain and simple fun... or just to get a task done. Therefore we use Small Basic. You will have an application up and running in a matter of minutes. You will understand exactly how it works and be able to write text programs, graphical user interfaces, and advanced drivers. It is so simple; you don't even need to be an adult!

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.

The Basics, New Ideas & Applications Build digital electronics from the ground up—and take it all the way to practical circuits you can use. This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on. From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits. Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs. Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters. Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.
