Rebuilding British Commerce and Industry-only memory (EPROM), and random access memory (RAM); find some peripherals; and then wire up the numerous address and data bus lines. After all that, you still had a pretty limited 8-bit system with no operating system. Today, you can acquire a 64-bit ARM quad-core system on a chip (SoC) with 1GB o

With the correct type of adapter and Pi configuration, you can repurpose some used VGA LCD screens. VGA monitors will eventually become scarce, but while they last

Exposition

One way to cost effectively expand the number of Pi inputs is to attach one or more 74HC165 CMOS chips. These are available from digikey.com for as little as a dollar. Figure 9-1 illustrates an example of the 16-

This chapter will examine the Microchip MCP23017 peripheral chip, which can offer any combination of 16 GPIO ports (in DIP form), each of whi
