Circuit Components Half of the struggle in electrical engineering (in practice) is finding the right components to assemble your circuits with. Below are rough notes and lists of the components we have encountered and loved (or not), that we like to maintain internally as a pointer-bank, and publish externally to help others weed through digikey and the like.
