    Thames & Kosmos has long been known for putting together quality science kits. They have now teamed up with Nick Dossis to write an introduction to basic electronics. This book helps the reader put together their own workshop with essential basics and offers instructions for building your own circuits.

    The items needed to complete the circuit projects in this book are common and accessible. This isn't a "pick up and go" type of project book; you will want to spend time gathering the materials needed – a great father-son project or for the electronics enthusiast who want more than a boxed kit. This might even be a good lab option at the high school level. This book covers the basics and teaches the different types of circuits and items used to complete circuits – switches, resistors, capacitors, diodes, transistors, and more. Every chapter is a project which offers background information, experiment guidelines, safety warnings, circuit diagrams and how it works, hints for successfully completing the project, and a detailed list of things you will need for the project. Complete projects such as building a working telephone, water sensor, pressure-sensitive mat, and sound effects generator – there are 17 projects in all! The best part is that there is no soldering – projects are completed on a breadboard. Electronics supplies can usually be purchased at places like Radio Shack or even online. If you are unsure about where to purchase, there is a list of suggestions at the back of the book. This book does more than play at electronics, it could possibly be preparing your student for a future career path. 170 pages, pb. ~ Donna

    My childhood was plagued with overcomplicated electronics kits with massive breadboards and a tangle of resistors. After completing several of the 40 experiments, I feel this kit is much more concise than many and easy to construct. This hands-on lab is designed especially for those who need a knowledge of electronics leading to a career in electronics, computers or robotics. This Tronix Book 1 lab kit will provide a good foundation in basic electronics concepts and components. A 93-page workbook provides 40 briefly described lessons that follow a 3-step process: taking inventory of parts needed; building the circuitry; and performing the experiment (with procedure and observation). Experiments range from basic electronics lessons (how to use the circuit board, reading values, etc.) to component lessons (how diodes, resistors, photocells, transistors, etc. work) to more complicated electronic project lessons. My favorite experiment was the moisture detector. Others include the light controller, police siren and insanity alarm game. Additionally, 13 pages of lessons cover basic DC electronics (Ohm’s, Kirchhoff’s voltage and current laws, and resistors in parallel and in series). At the end of the workbook are 9 pages of Build-the-Schematic exercises, in which the more advanced student will view a schematic, read the theory behind each item and follow the procedure to build. Students can also fill in the date of each schematic’s completion. Parts are identified visually and also according to lab used: includes a 6.5” x 1.5” breadboard, a 9V battery, ceramic disc capacitors, light emitting diodes, an integrated circuits/timer, a photocell, a battery snap, a timer, 3 standard LEDs,2 silicon rectifier, 4 pnp transistors, a speaker, resistors, a diode, a push-button switch, potentiometer, semiconductors, and 20 solid wires at different OHM ratings. While most helpful if learning alongside someone with some electrical experience, the variety of in-depth experiments allow high school students to have plenty of fun while learning ohm’s law, circuits in parallel versus series and voltage principals. ~ Steve

    As a kid I would always take apart my toys that stopped working. Unfortunately, I never learned much and these parts eventually made it to the back of my shelf. Having had this manual, subtitled Salvage and Reuse Motors, Gears and Switches from Your Old Electronics, I would have understood exactly what made up those toys and household items and even been able to repurpose them. Even as a current tech junkie, this book showed me a good deal about the inner workings of common household items. The pictures, though black and white are great and annotated with helpful details, taking you fairly step-by-step. The book describes over 50 common electrical appliances and tools (such as an electric drill, a Walkman, typewriter, laptop screen, a hairdryer, a VCR and guitar), the tools you’ll need to disassemble them, the steps to take and the treasure you’ll find within. Also included are proper disposal issues for the non-treasures. Take these inner components and use them to build all sorts of useful projects. Who wouldn’t want to turn their old electric toothbrush into a working submarine model, for example? With 224 softcover pages, you’re bound to stay busy learning about and collecting the inner treasures of our most common electronics. ~ Steve

    What is electricity? How do magnets work? Electricity and Magnetism works to unfold the answers to these questions and explain the connection between the two. It was only in the last century that scientists discovered how to generate the electricity that powers our lights, heating and air conditioning systems, and electronic devices. Although current electricity is the most important form of electricity, the book also covers natural or static electricity. Surprisingly, magnetism was discovered over 2000 years ago, but it was not until relatively recently that scientists began to investigate its mysterious properties. Learn all about magnetic forces and fields and how to create your own magnet. ~ Enh

    At some point, if you want to progress past beginner electronics kits, you're going to have to learn how to solder (or, in my case, when my blender broke down…). This kit makes it easy to learn by starting with a simple project (a flashing European siren), and giving you all the tools you need to do it. The kit includes a soldering iron, side cutters, solder, a circuit board, solder wick, a speaker, wire, a battery snap, resistors, capacitors, semiconductors, and an instruction booklet, which contains a lengthy introduction to the project, including identifying resistor and capacitor values, reading resistor colors, using the soldering iron, soldering practice, and a theory of operation, before the user even begins to assemble the PC board. Instructions for this step are found towards the end of the booklet, with troubleshooting tips, unsoldering practice, a glossary and a quiz. If done correctly, the siren will sound and the lights will flash. This looks like a great kit to learn basic soldering. Maybe I should get one for more practice! - Jess CHOKING HAZARD (1).
