Creating usable functionality from such devices was done by hand using pencil and paper as well as lots of trial and error. Once a suitable design was solid enough to try out, the circuit was prototyped either by wirewrapping or soldering depending on the complexity of the circuit. Needless to say, even the simplest design required hours of checking and rework to achieve the desired results. So much for history. Today things are far simpler. Just about anything the hobbyist needs for his design is either available already or can be programmed into a generic processor circuit. The type of design the hobbyist performs and that you will adopt is through the use of building blocks. You pick the parts that you need and connect the appropriate lines (wires) between them. While it really is that simple, a sound knowledge of basic electronics principles goes a long way to helping create a circuit that works as opposed to a mess of wires, time, and money that has no hope of succeeding. The good news is that vendors of the parts that you ll use want you to succeed. They provide very detailed specifications that can be several hundreds of pages for a single part. Their web sites contain application notes on how to use the parts in typical circuits, FAQs covering every aspect of the part, forums to provide user interaction with each other and company representatives, and many provide webinars available any time day or night to view.

While the glut of information can be a problem in itself, forcing the designer to look through potentially thousands of pages for information about a single part, most parts in a family tend to work well together. Sticking with a single manufacturer and its recommended product lines gives the novice a good way to get started. The best thing that can help the beginning designer is to purchase evaluation or prototyping kits such as that shown in Figure 10 2 for the PIC microcontroller line from Microchip.

For the designer of iPhone accessories who doesn t have an extensive hardware engineering background, but wants to begin developing hardware, evaluation kits cannot be beat. For any processor family that a designer would consider to use in an accessory design, there are several evaluation kit options. These kits offer the hardware you need to get started. They include the processor with its associated circuitry, software development tools (generally a limited set), and tutorial projects to get you going. Each project builds upon the last and the whole course can generally be completed in a day or two. None of these kits will turn you into an electrical engineer, but they will give you enough knowledge to get you moving in the right direction. The kits range in price from less than a hundred to several hundred dollars. As discussed, the central part of your hardware accessory will be some type of processor, i.e., a small computer. Most everything else in your accessory will be supporting data acquisition. In general, most accessories are either going to take data into the iPhone or send data out.

So really, your accessory will be (1) a processor of some type, (2) a connector to get to the iPhone (provided by Apple), (3) some other I/O devices such as buttons, knobs, LEDs, etc., to move data back and forth, and (4) other support circuitry such as power or security. Now that you know the basic design of your accessory, you want to look at the process involved to get from your idea to a product that you can test with your iPhone.
