Low-Cost Test Equipment Projects You Can Build

Everyone who works with electronic circuitry on a regular basis needs test equipment. But commercially sold meters and probes are very expensive, and often more than the average home experimenter needs. This money-saving project book aims to solve that dilemma by providing plans and instructions for building two dozen inexpensive test instruments - both analog and digital - for the workbench.;This book instructs hobbyists how to construct a voltage range detector, digital voltmeter, transistor/diode tester, deluxe logic probe, light meter, temperature range detector, sine wave audio oscillator, sweep function generator, and many other essential pieces of test equipment - each in two hours or less, using components available at any local electronics store, The complete set of diagnostic tools featured here would cost thousands of dollars if purchased from a dealer, but this book shows readers how easy it is to build them at home for a fraction of the price.;Delton T.
