The book is for everyone who likes to tinker in their home workshop In Section 1: Ideas and Approaches, the author looks at how you can develop new projects and inventions. How to think laterally, how to get advice, and when you should stop theorising and start testing In Section 2: Projects you can build, there is everything from a solar-heated cat or dog kennel - to a jet-powered scooter From a simple and very cheap seismograph that's sensitive enough to detect people walking up to your front door, to how you can build speakers into the walls and floor of your house. If you'd like to...

Would you like to be able to test your car modifications without needing a flow bench, dyno and wind tunnel? You can Welcome to a series of great, down-to-earth and practical testing techniques you can carry out on the road without having to spend a lot of money. Test the flow of airboxes, airfilters, cat converters and mufflers. Aerodynamically test your car and improve the flow through intercoolers and into airboxes. Analyse handling, turbo response, cam timing changes and engine management tuning changes. And not only can you test the results of your modifications, you can also make...

Author Julian Edgar spent over a decade writing new car tests and, very unusually for a motoring journalist, also modifying his own cars and writing about those modifications. Here are his thoughts on topics as diverse as whether a dyno is a good place to develop car modifications, the joys of left-foot braking, whether people who choose to buy thirsty cars should then complain about the price of fuel, and what it's like when the throttle jams fully open. Over 50 topics are covered - from a scathing criticism of those who choose to waste away their lives, to how it's impossible to have a...

Do you want to be able to fit and tune programmable engine management, working from home? You can This book covers the selection, wiring and tuning of programmable ECUs, all done without access to a dyno and with a totally hands-on approach. From the step-by-step of tuning idle, throttle enrichment and high- and low-loads, to tuning for best fuel economy. Mapping exhaust gas recirculation for better throttle response, to safely retarding ignition timing with increased intake air temps. PID tuning loops explained in easy to understand language, directly measuring the crank reference indicator...

This book will show you how to write strong and effective arguments of the sort used in government, private business and non-government organisations. It is practical, down to earth and easy to understand. It is not a study of logic, or premises, or all those other things you always seem to find in books on writing arguments Instead, it uses easy-to-remember rules that you can employ in all documents, large or small. Many people write rather muddled arguments that are difficult to follow and often do not result in the outcome intended by the author. So if you can write clear, precise and...

Here's a book on building your own speakers that's packed with great new ideas. Building a pair of underfloor 15-inch subwoofers for your home, integrating quality ported enclosures into your walls or ceiling - even developing your own spherical-shaped hi-fi speakers. There's also coverage of software to design speaker enclosures, to determine the specs of second-hand or unknown drivers, and to measure the performance of your new speakers. Here are ideas that you can take and apply for yourself, without needing to buy expensive brand-name drivers or have high-level woodworking skills....

It's normally difficult to make interior car trim panels that look right. That's especially the case when the panel needs to curve in two directions at once - to be compound curved. But in this short booklet, author Julian Edgar shows a completely new way of making these panels. It's quick, easy (no hours of sanding ) and gives excellent results. The approach uses a very special technique that produces sandwich layer foam panels that can easily be trimmed in carpet or cloth. The panels can be curved however you like, and provide good sound and heat insulation. The panels can be produced at...

The original Honda Insight is one of the world's most extraordinary cars. Boasting an all-aluminium body and incredible aerodynamics, the Insight was also a full hybrid. When released, it was the world's most fuel-efficient car - and by a huge margin. This book looks at the anatomy of the Insight, and its modification. The modifications range from the very simple (improving the quality of the gear shift by changing the knob) to the most complex (fitting programmable engine management and a turbo) - and everything in between. It also covers what you need to do to keep the high voltage battery...
