A Hands-On Lab Course
This introduction to circuit design is unusual in several respects. First, it offers not just explanations, but a full course. Each of the twenty-five sessions begins with a discussion of a particular sort of circuit followed by the chance to try it out and see how it actually behaves. Accordingly, students understand the circuit's operation in a way that is deeper and much more satisfying than the manipulation of formulas. Second, it describes circuits that more traditional engineering introductions would postpone: on the third day, we build a radio receiver; on the fifth day, we build an operational amplifier from an array of transistors. The digital half of the course centers on applying microcontrollers, but gives exposure to Verilog, a powerful Hardware Description Language. Third, it proceeds at a rapid pace but requires no prior knowledge of electronics. Students gain intuitive understanding through immersion in good circuit design.
The course is intensive, teaching electronics in day-at-a-time practical doses so that students can learn in a hands-on way.
The integration of discussion of design with a chance to try the circuits means students learn quickly.
The course has been tried and tested, and proven successful through twenty-five years of teaching.
The book is practical: it avoids mathematics and mathematical arguments and even includes a complete list of parts needed in the laboratory exercises, including where and how to buy them.
The much-anticipated new edition of 'Learning the Art of Electronics' is here! It defines a hands-on course, inviting the reader to try out the many circuits that it describes. Several new labs (on amplifiers and automatic gain control) have been added to the analog part of the book, which also sees an expanded treatment of meters. Many labs now have online supplements. The digital sections have been rebuilt. An FPGA replaces the less-capable programmable logic devices, and a powerful ARM microcontroller replaces the 8051 previously used. The new microcontroller allows for more complex programming (in C) and more sophisticated applications, including a lunar lander, a voice recorder, and a lullaby jukebox. A new section explores using an Integrated Development Environment to compile, download, and debug programs. Substantial new lab exercises, and their associated teaching material, have been added, including a project reflecting this edition's greater emphasis on programmable logic.

The Mendocino Motor AR O-8 is a magnetically levitated, solar powered electric motor as a kit.
Light Becomes Movement
The solar-powered Mendocino motor seems to float in the air. At first glance, you can't see why the rotor is turning at all. This is the magic of the motor.
The Lorentz force is a very small electrical force. In a classroom setting, it is detected by a current swing in the magnetic field. With the Mendocino motor, we have succeeded in developing a beautiful application that uses this weak force for propulsion. Due to its concealed base magnet, the motor will fascinate technically inclined observers.
In bright sunlight, the motor can reach a speed of up to 1,000 rpm. More impressive, however, is that even the faint glow of an ample tea light (D = 6 cm with a flame height of about 2 cm) is sufficient to drive the motor. The motor is not yet an alternative source of energy, even though it looks tempting. Presumably, it will remain an attractive model until a resourceful mind disproves this assumption.
Dimensions
All solar cells 65 x 20 mm
Mirror diameter: 25 mm
Rotor weight: approx. 150 g
Model length: 160 mm
Model width: 85 mm
Frame height: approx. 85 mm
Frame material: black acrylic
Tube made of highly polished aluminum
Mirror color: silver
The Mendocino motor’s easy-to-follow instruction manual includes more than 70 illustrations. It describes a safe and practical approach to construction but also gives you the freedom to try your solutions.
Partly Pre-Assembled Kit
A portion of the kit comes pre-assembled. Bonding the borosilicate glass pane to the acrylic surface requires specialized knowledge and aids. We do not want to impose this on the hobbyist. For instance, the base magnet is attached to the aluminum tube.
As a hobbyist, you will need some know-how and appropriate tools: carpet knife, soldering iron and tin, hot glue, pliers, and a clamp or ferrule to fix the supplied assembly aid. A lot of fun is guaranteed!
Programming the Finite State Machine with 8-Bit PICs in Assembly and C
Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information.
This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer.
A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly.
Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming.

The Qwiic pHAT connects the I²C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses, you can stack as many sensors as you’d like to create a tower of sensing power! The Qwiic pHAT V2.0 has four Qwiic connect ports (two on its side and two vertical), all on the same I²C bus. We've also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button (with the option to shut down the Pi with a script). Also updated, the mounting holes found on the board are now spaced to accommodate the typical Qwiic board dimension of 1.0' x 1.0'. This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header and the NVIDIA Jetson Nano and Google Coral.
