6. Hardware: Tools and Supplies

Chapter 6. Hardware: Tools and Supplies

Byrne’s Law: In any electrical circuit, appliances and wiring will burn out to protect fuses.

Robert Byrne

Although it may be possible that one could implement a complex instrumentation system and never touch a tool more complicated than a screwdriver, there is a high probability that a soldering iron, wire cutters, and a digital multimeter (DMM) will come in handy at some point—particularly if things don’t work quite right from the outset, or if there’s a reason to be concerned should something accidentally be damaged.

In this chapter, we’ll look at what might go into a basic toolkit for doing instrumentation work. It isn’t much and could all easily fit in a small box on a shelf somewhere. Additionally, as there may very well come a time when you really need to see what’s going on in your system, I’ve included a short discussion of the two pieces of test equipment that can help eliminate the guesswork and get to the root of an interface or control problem: the oscilloscope and the logic analyzer.
