The COVID lockdown prompted me to re-engage with long-time hobbies, namely electronics and audio. I typically do not design all my stuff from scratch; I pull together components others have designed and shared where it makes sense to do so. When a special component is needed to accomplish a certain goal, then I will design and build it myself. You may find yourself in a similar situation as you get deeper into the hobby, and that is what makes it fun.
I have also scribbled down some musings and personal opinions about what I know (or think I know) concerning various related topics in my articles section of the website.
