Around that age, I wrote a letter to Tandy (Radio Shack), proposing that I write a hobby electronics book.

In hindsight, I wasn't knowledgeable enough to write a printed book's worth of material (maybe a few modern blog posts, at best). But at the time, I knew more about electronics than the other 29 kids in my grade school class, and that constituted most of my worldview, so why couldn't I write a book.

I loved the Forrest Mims books, and, like any kid, wanted to mimic the things that I saw grownups doing.

Someone at Tandy might have realized that I was just an enthusiastic kid, but in any case, they wrote me a nice letter back. The company didn't wish to develop a book at this time, but if I did so on my own, they would be happy to review a copy off the press.

(Edit: I mean, there was a mailing address right there, on the back cover. In a kid's mind, why couldn't you simply mail a letter to that address. https://archive.org/details/gettingstartedin00mims/page/n131... )
