This book fills a niche, at least for me. It has clear, concise descriptions of components that you can’t get anywhere else. Datasheets are way too detailed and don’t provide the “common knowledge” that exists about items. It more closely resembles a wiki entry, but spells out how to use an item as opposed to just basic facts like Wikipedia does. It doesn’t try to be all inclusive and focuses mainly on hobby uses.
Really enjoying reading this!
