Appendix A. Construction Techniques
Building the more advanced projects in this book might require you to learn some new skills. Most electronic products today use construction techniques that involve parts so small you need a microscope to handle them. Fortunately, larger electrical components that you can reasonably work with are still available. Methods to build with these parts have been around for decades, and everything you need is available at Radio Shack or other electronic distributors. For the I2C bus projects in Chapter 13, Mindsensors sells prototype boards for the PCF8574 and PCF8591 integrated circuits. They save you from making many of the connections and include the unique NXT socket that saves you from having to cut cables.
