Although most of the resources on this site will probably only be used by experienced hardware designers, a substantial amount of other information is provided that is ideal for beginners. An impressive collection of how-to guides and tutorials covers everything from mouse cleaning to basic soldering to printed circuit board fabrication. A complete online handbook, titled Batteries in a Portable World, explains how rechargeable batteries and chargers work. For the advanced electronics designer, circuit diagrams of several common devices are given. Additionally, tables describing "the function of each wire in a cable or each pin in a connector," also called pinouts, are available for many common interfaces.
