Well here’s a tip that works for me - and why I suggested a purpose for your implant: I find it easier to dive into the specifics of anything if it’s to achieve something. Learning for the sake of learning bores me to tears. I only learn anything if I’m forced to to make something work for me.
Hence my suggestion: since you have an implant, figure out what you’d like to do with it and run with the idea. You’ll learn everything there is to know about the subject just by making your project a reality. And you already have all the bits and pieces to achieve most of it.
