Anyone can edit Simple Electronics Wiki. It's a wiki that aims to be a succinct and easily understood introduction to practical entry-level electronics, as well as being a useful reference. The intended audience for this wiki is the amateur experimenter. In fact the best way to learn about electronics is by doing practical experiments.
See something that needs fixing? Go ahead and edit it, but keep it simple.
