The author, Johan Basse Bergqvist, is an engineer, a musician, and an audiophile with a knack for building projects that produce the desired results. The combination of these skills leads to a uniquely valuable perspective on audio design that is routinely reflected in the book and passed on to the readers. Several design projects are provided, 40 in total. The designs are explained, and the unique features or methods he uses are described in further detail. Each design includes detailed schematics and a complete parts list. Many of the projects also include layout documentation in the form of CAD photos of the PCB layouts. The range of projects is very diverse and includes something that will appeal to everyone. Stereo amplifiers, guitar and bass amplifiers, preamplifiers for phono, and microphones are all covered. Several variants for each type are included, and the power amplifier designs range from a few watts to several hundred watts, which meet almost any power level you might tackle.

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.

If you have the right tools, designing a microprocessor shouldn’t be complicated. The Verilog hardware description language (HDL) is one such tool. It can enable you to depict, simulate, and synthesize an electronic design, and thus increase your productivity by reducing the overall workload associated with a given project.Monte Dalrymple’s Microprocessor Design Using Verilog HDL is a practical guide to processor design in the real world. It presents the Verilog HDL in a straightforward fashion and serves as a detailed introduction to reducing the computer architecture and as an instruction set to practice. You’re led through the microprocessor design process from start to finish, and essential topics ranging from writing in Verilog to debugging and testing are laid bare.The book details the following, and more: Verilog HDL Review: data types, bit widths/labeling, operations, statements, and design hierarchy Verilog Coding Style: files vs. modules, indentation, and design organization Design Work: instruction set architecture, external bus interface, and machine cycle Microarchitecture: design spreadsheet and essential worksheets (e.g., Operation, Instruction Code, and Next State) Writing in Verilog: choosing encoding, assigning states in a state machine, and files (e.g., defines.v, hierarchy.v, machine.v) Debugging, Verification, and Testing: debugging requirements, verification requirements, testing requirements, and the test bench Post Simulation: enhancements and reduction to practice Monte Dalrymple received a BSEE (with highest honors) and an MSEE from the University of California at Berkeley, where he was elected to Phi Beta Kappa. Monte started his career at Zilog, where he designed a number of successful products, including the Serial Communication Controller (SCC) family and the Universal Serial Controller (USC) family. He was also the architect and lead designer of the Z380 microprocessor. Monte started his own company, Systemyde International Corp., in 1995, and has been doing contract design work ever since. He designed all five generations of Rabbit microprocessors, a Z180 clone that is flying on the Juno mission to Jupiter, and a Z8000 clone that flies in a commercial avionics air data computer. Monte holds 16 patents as well as both amateur and commercial radio licenses. Monte wrote 10 articles for Circuit Cellar magazine between 1996 and 2010. He recently completed a side project to replace the CPU in an HP-41C calculator with a modern FPGA-based version.

The Piccolino rapid development board can be used to design microcontroller circuits quickly. The Piccolino has a fast 16f887 PIC microcontroller, voltage regulator, and communications module, and can be easily extended using its four headers. This e-book contains 30 projects based on the Piccolino. We'll use its unique communications facilities and get the Piccolino to communicate with programs on a PC. On the PC, we use the free programming language Small Basic. You can use this to create Windows programs with buttons and graphs quickly. You will learn how to analyze components such as inductors, capacitors, and OPAMPs, and how to display the measurement results in a graphical format. This will help you to design your circuits easily. We will then start to adapt to the Piccolino. We'll add components to it to make it more powerful, with extra features such as flow control and digital to analog conversion. The clear instructions will enable you to design and build your adaptations. This way you can make your custom designed Piccolino. We'll end up making an extension: a PCB that that can be mounted on the Piccolino headers. As an example, we'll design and build an extension for an LCD. You can use the included board layout to make your PCB or have it made for you. At the same time, you will learn how to make your extensions. The only limitation is your imagination! The clear descriptions along with circuit diagrams and photos, will make the building of these projects an enjoyable experience. Each project has a clear explanation of the reasons why it was designed in a particular way. This helps you learn a lot about the Piccolino, as well as Small Basic, and the components that are used in this e-book. You can adapt the projects to suit your requirements or combine several projects.

Er zijn niet zoveel boeken te vinden over het ontwerpen en bouwen van zenders met een klein uitgangsvermogen. Dit boek beschrijft nauwkeurig de werking en bouw van maar liefst twintig audio- en videozender(tje)s. Daarmee biedt het aan de amateur-elektronicus, technicus, zendamateur en andere radio-enthousiasten het noodzakelijke materiaal om zich verder te bekwamen op dit gebied. Er wordt slechts weinig aandacht besteed aan de theorie, maar dat heeft een groot voordeel: ruim 300 pagina’s vol praktijk. De zenders, sommige eenvoudig, andere meer gecompliceerd, werden speciaal ontworpen voor het gebruik door amateurs. Ze werken tussen 150 kHz en 1300 MHz. De gebruikte techniek dateert vooral uit de jaren 90. Dit mag op het eerste gezicht een tekortkoming lijken, maar het is juist een extra argument voor publicatie. De technieken hebben zich inmiddels bewezen en er worden eenvoudige, goedkope en nog steeds goed verkrijgbare onderdelen gebruikt. Dit boek richt zich dus in de eerste plaats tot de potentiële gebruiker van HF-technieken, die er niet voor terugschrikt om dit soort schakelingen in elkaar te zetten. De schakelingen zijn probleemloos na te bouwen (nog een voordeel van zich bewezen technieken). Om dat te bereiken hebben de auteurs veel aandacht besteed aan: de testprocedures voor elke schakeling, de onderdelenlijst, instructies voor het vervaardigen van de spoelen en voor de afregeling. Bij de meeste schakelingen is bovendien een printontwerp afgedrukt. Naast zenders voor o.a. FM-stereo, AM, VHF-FM-amateur, R/C-TV, 40-m-CW-zender, 10-m-SSB, 2-m-NBFM, FM-video-link en amateur-TV vindt u in dit boek ook verwante schakelingen, zoals een down-converter voor 400, 900 en 1300 MHz en een HF-vermogensmeter.
