In this chapter, we took a look at some basic electronics that were to be used to power the Pi and external devices and to amplify the audio from the audio output on the Pi.

We also took the first steps to design and manufacture custom enclosures and fittings for hardware projects by adapting an existing case for the enclosure of the speaker system. In later projects in this book, we will use these skills to manufacture enclosures from scratch.

In the next chapter, we will look further into designing and manufacturing customized enclosures, as we build a mini tabletop arcade machine.
