  • Machine Learning with Python for PC, Raspberry Pi, and Maixduino

    Machine Learning with Python for PC, Raspberry Pi, and Maixduino

    1 review

    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.

  • Multitasking with Raspberry Pi

    Multitasking with Raspberry Pi

    Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel.This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project.

  • DVI Sock for Raspberry Pi Pico

    DVI Sock for Raspberry Pi Pico

    Unlike other Raspberry Pi boards, the Raspberry Pi Pico does not have a built-in video output.However, thanks to programmable IO (PIO) and this Pico DVI Sock, it is possible to add a DVI video output to the Raspberry Pi Pico!The Pico DVI Sock was developed by Luke Wren, a Raspberry Pi engineer, in his spare time. He has published the design online under a CC0 license, so everybody can build the hardware from his provided files.The physical video interface of the Pico DVI Sock is an HDMI connector, but it outputs a DVI signal. Historically, HDMI is a successor to DVI – so DVI signals can be simply transmitted using HDMI. Simple passive adapters allow you to connect HDMI cables to a DVI port.The DVI Sock can be soldered to one end of the Raspberry Pi Pico. Thanks to the castellated edges of the Pico, soldering is very easy.

  • Raspberry Pi 4 OR 5 AND Pico

    Raspberry Pi 4 OR 5 AND Pico

    Cool Projects for Test, Measurement, and Control The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi. These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair. The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities. Some practical projects from the contents: USB between Raspberry Pi 4 or 5 and Pico I²C Communication and Pico as an I²C device Voltmeter and Computer Thermometer Pico W as a Web Server and WLAN Scanner Frequency Meters and Generators OLED Displays on Raspberry Pi 4 or 5 and Pico Energy Saving Monitor Which Astronauts are in Orbit?

Buy a Raspberry Pi

What is Raspberry Pi? Why do you need a Raspberry Pi board? What are the benefits?

Raspberry Pi is a minicomputer or a so-called Single Board Computer (or SBC for short) from the Raspberry Pi Foundation from Cambridge (GB). In a single-board computer, all important components such as the processor, RAM and GPU are mounted on one board.

The foundation published the first Raspberry Pi version in 2012 with the idea of promoting computer science as a school and study subject. The main goal to achieve this was a retail price of $35 that should be affordable for everyone.

Elektor also wanted to arouse early interest in computer science and electronics among pupils and students. As an official Raspberry Pi reseller, Elektor has direct personal contact with the Raspberry Pi developers in Cambridge and with the actual intellectual father of the Raspberry Pi, Eben Upton. Elektor not only offers official Raspberry Pi hardware, but also offers its customers interesting first-hand projects, reviews, tutorials and specialist books. Elektor thus occupies a special position among all Raspberry Pi dealers.

In addition to the currently available Raspberry Pi boards Elektor offers you official Raspberry Pi accessories and a carefully selected selection tested third party products (construction kits, HATs, power supplies, cases, displays, cameras, books and miscellaneous. We also have an extensive range of RP2040 products based on the RP2040 microcontroller chip developed by the Raspberry Pi Foundation.

Buying a Raspberry Pi board: what can you do with it?

What makes the Raspberry Pi so special? This small, full-fledged, credit card-sized computer has won the hearts of software and hardware developers around the world and continues to reinvent itself with each new hardware version. With more than 20 million boards sold, Raspberry Pi has turned the electronics world upside down. It doesn't matter if you are a beginner or a professional developer, Raspberry Pi is the universal tool for every electronics technician! Use the Raspberry Pi for your own developments, control your smart home products with it or use it as a media player in the living room for streaming. Raspberry Pi cuts a fine figure in every area. The application possibilities are almost endless. The steadily growing community develops fun, but above all useful projects that are easy to make yourself.

Smart Home projects with Raspberry Pi

Today, a Smart Home is one of the most used applications for the Raspberry Pi. The reason for this is logical because a Smart Home provides more comfort in the home and makes saving on energy costs easy. Below you will find three of the most commonly used applications of Raspberry Pi in a Smart Home environment

Home automation system

The Raspberry Pi can be used to build a home automation system that allows you to perform tasks automatically. This includes controlling lighting, heating, entertainment and air conditioning.

Home monitoring

Home monitoring is a system that uses sensors to take measurements of your home environment and transmit this information to a central device. The system can take measurements of: temperatures, humidity, light intensity and movement. Use home monitoring to monitor your home environment, allowing you to use alarm systems, security cameras and other devices to protect your home.

A good example of this is when you close your roller shutters automatically as soon as it threatens to get too hot. This way you can easily restore the heat in your home.

Smart switches

A smart switch is a device used to turn electrical appliances on and off remotely. It is a wireless device that is connected to your home network and can be controlled with a mobile app, a remote control or a voice assistant.

A good example of smart switches combined with Raspberry Pi is turning off lights when you watch a movie via Kodi. You can even go so far that when you pause the movie, the lights come back on.

Buy your Raspberry Pi from Elektor
