Make: Electronics Components Pack 2 is the second companion pack to our popular Make: Electronics book covers experiments 12 - 24 from Chapters 3 & 4. We've spent countless hours sourcing these hard-to-find parts - more than 130 pieces - so you don't have to. This pack continues where Components Pack 1 left off and delves into integrated circuits, digital electronics and soldering skills. All parts are spec'd directly from the book and author Charles Platt (see below for the list of contents). Please note: Many, but not all, of the components needed for Chapters 3 & 4's experiments are found in Components Pack 1, so we recommend having that kit already or the parts necessary for the experiments.
