The Red Pitaya (STEMlab) is a credit card-sized, open-source test and measurement board that can be used to replace most measurement instruments used in electronics laboratories. With a single click, the board can transform into a web-based oscilloscope, spectrum analyser, signal generator, LCR meter, Bode plotter, and microcontroller.
The Red Pitaya (STEMlab) can replace the many pieces of expensive measurement equipment found at professional research organisations and teaching laboratories. The device, that based on Linux, includes an FPGA, digital signal processing (DSP), dual core ARM Cortex processor, signal acquisition and generation circuitry, micro USB socket, microSD card slot, RJ45 socket for Ethernet connection, and USB socket – all powered from an external mains adaptor.
This book is an introduction to electronics. It aims to teach the principles and applications of basic electronics by carrying out real experiments using the Red Pitaya (STEMlab). The book includes many chapters on basic electronics and teaches the theory and use of electronic components including resistors, capacitors, inductors, diodes, transistors, and operational amplifiers in electronic circuits. Many fun and interesting Red Pitaya (STEMlab) experiments are included in the book. The book also makes an introduction to visual programming environment.
The book is written for college level and first year university students studying electrical or electronic engineering.

An 8-in-1 test & measurement instrument for the electronics workbench
A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more.
The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts.

If you are going to be drilling, we recommend drilling on FR1 substrates. Unlike FR4, FR1 dust does not contain fiber glass. It is also a softer material, which means a less wear and tear on the drill bits. Download the template and incorporate them into your design here. 10 substrates included.
This book is intended as a highly-practical guide for Hobbyists, Engineers and Scientists wishing to build measurement and control systems to be controlled by a local or remote Personal Computer running the Linux operating system. Both hardware and software aspects of designing typical embedded systems are covered in detail with schematics, code listings and full descriptions. Numerous examples have been designed to show clearly how straightforward it can be to create the interfaces between digital and analog electronics, with programming techniques for creating control software for both local and remote systems. Hardware developers will appreciate the variety of circuits, including a novel, low cost modulated wireless link and will discover how using Matlab® overcomes the need for specialist programming skills.
Software developers will appreciate how a better understanding of circuits plus the freedom offered by Linux to directly control at the register level enables them to optimize related programs. There is no need to buy special equipment or expensive software tools in order to create embedded projects covered in this book. You can build such quality systems quickly using popular low-cost electronic components and free distributed or low-cost software tools. Some knowledge of basic electronics plus the very basics of C programming only is required.
Many projects in this book are developed using Matlab® being a very popular worldwide computational tool for research in engineering and science. The book provides a detailed description of how to combine the power of Matlab® with practical electronics.
With an emphasis on learning by doing, readers are encouraged by examples to program with ease; the book provides clear guidelines as to the appropriate programming techniques “on the fly”. Complete and well-documented source code is provided for all projects.
If you want to learn how to quickly build Linux-based applications able to collect, process and display data on a PC from various analog and digital sensors, how to control circuitry attached to a computer, then even how to pass data via a network or control your embedded system wirelessly and more – then this is the book for you!

Elektronica moeilijk? De titel van dit boek geeft het antwoord!
In deze 3-in-1-band wordt de elektronica vanuit de praktijk benaderd. Dat wil zeggen veel praktijk in de vorm van experimenten en een minimum aan theorie. Zo raakt u stap voor stap vertrouwd met de behandelde onderwerpen. Daarbij ontstaan gaandeweg ook een flink aantal praktisch bruikbare schakelingen. Het gaat bij de elektronicahobby tenslotte om het bouwen of uitdenken van allerlei praktische of leuke schakelingen.
Aan het eind van elk deel is een aanhangsel opgenomen met aanvullende informatie en de gegevens van een groot aantal elektronische componenten, zodat na dit boek ook eigen ideeën en experimenten kunnen worden aangepakt.
In deze 3-in-1-band zijn de eerste drie delen uit de serie “Elektronica echt niet moeilijk” samengevoegd:
Deel 1: experimenten met gelijkstroom
Deel 2: experimenten met wisselstroom
Deel 3: experimenten met digitale techniek
