This book describes in detail how to construct some simple and inexpensive, but extremely useful, pieces of test equipment. stripboard layouts are provided for all designs, together with wiring diagrams where appropriate, plus notes on their construction and use. The following designs are included: AF generator, test bench amplifier, high resistance voltmeter, transistor tester, capacitance meter, AF frequency meter, analogue probe, CMOS probe, TTL probe. Apart from providing the home constructor with a useful range of test gear, building these projects should also be an interesting as rewarding exercise in its own right. The designs are suitable for both newcomers and more experienced hobbyists alike.
