This Raspberry Pi Pico is a departure from previous Pi models in that it is not a Linux computer but rather a microcontroller board similar to Arduino. The Raspberry Pi Pico's primary selling features are its low price of $4 and indeed the RP2040 chip, which offers ample capacity for embedded applications and lets individuals of any age or skill to learn to code and build electronics. If you already own a Windows, Apple, or Linux computer, or perhaps another Raspberry Pi, you're halfway to the use of the Raspberry Pi Pico with your next project.

This book covers both the physical properties of sensors for converting physical quantities into digital data and the design of complex measurement and data analyzing systems. In respect thereof, a unique treatment of measurement and sensor systems is given from a physical point of view, wherein a focus is on innovative links between physics and engineering sciences. The acquisition of data by measurement systems equipped with appropriate sensors is a fundamental activity in science and industry. The book is divided into eleven chapters, each chapter starting with a discussion of measurement systems based on the relevant sensor concept followed by an in-depth description of the data processing and analysis procedures.

Tells how to write an Arduino program to detect mechanical, magnetic or angular velocity disturbances anywhere within 600 yards line-of-sight of your lora base station, and to issue alerts when the disturbances exceed preset levels, which may be programmed remotely from your base station, which is a different Arduino program on the same board type. Provides complete detail, including requirements, architecture, design, hardware build, and source code for a Lora Radio remote sensing system. The system is built with readily available, inexpensive processor and multi-sensor boards available from and supported by Adafruit and Arduino. The remote sensing board(s) expect a lora radio base station to supply sensing parameters, and alarm when alerts are received.

This book organizes principles and methods of signal processing and Machine Learning into the framework of coherence. The book contains a wealth of classical and modern methods of inference, some reported here for the first time. General results are applied to problems in communications, cognitive radio, passive and active radar and sonar, multi-sensor array processing, spectrum analysis, hyperspectral imaging, subspace clustering, and related. The book begins with a review of classical results in the physical and engineering sciences where coherence plays a fundamental role. Then least squares theory and the theory of minimum mean-squared error estimation are developed, with special attention paid to statistics that may be interpreted as coherence statistics. A chapter on classical hypothesis tests for covariance structure introduces the next three chapters on matched and adaptive subspace detectors. These detectors are derived from likelihood reasoning, but it is their geometries and invariances that qualify them as coherence statistics. A chapter on independence testing in space-time data sets leads to a definition of broadband coherence, and contains novel applications to cognitive radio and the analysis of cyclostationarity.

The STM32F7-DISCO board is so right for a theremin implementation, it actually cried out for one. So here it is. This book provides complete requirements, architecture, design, code, debug, verification, and validation info, as well as all of the source code. ST was the first silicon vendor to introduce a Cortex-M7 chip. Like the M4, the M7 has a floating point processor, and a specialized I2S peripheral called the SAI (Serial Audio Interface, I guess). Floating point is a big help in computing envelopes for audio outputs. The M7 also runs twice as fast as the M4. The STM32F7-DISCO board includes an audio codec, the wm8994, and an audio output that works either for headphones or powered speakers. In addition it has a 420 x 272 touchscreen, and a TFT color LCD. The code for the digital theremin is written in C. The vendor libraries were written in C, so the choice was a no-brainer.

The IGBT Device: Physics, Design and Applications of the Insulated Gate Bipolar Transistor, Second Edition provides the essential information needed by applications engineers to design new products using the device in sectors including consumer, industrial, lighting, transportation, medical and renewable energy. The IGBT device has proven to be a highly important Power Semiconductor, providing the basis for adjustable speed motor drives (used in air conditioning and refrigeration and railway locomotives), electronic ignition systems for gasoline powered motor vehicles and energy-saving compact fluorescent light bulbs. The book presents recent applications in plasma displays (flat-screen TVs) and electric power transmission systems, alternative energy systems and energy storage, but it is also used in all renewable energy generation systems, including solar and wind power. This book is the first available on the applications of the IGBT.
