I originally started out with just a few pages I created that were relevant to various hobbies of mine (such as the ham radio math tools). As these various hobby pages grew in size and scope, I thought I'd put everything in one place for easier navigation. My goal is to eventaully expand these resources to cover some of my other hobbies, such as 3D printing and electronics.
