The rain stopped just long enough to tempt Mrs Widds and I out into the front yard …
… Yes, ’tis the season…
… look at this little beauty? Isn’t Mother Nature grand?
… until all is but a memory. We’ll do one last rake-around when the last leaves have fallen, but that’s it for Autumn, which is just as well because it’s starting to rain again.
I may have a practical mind but the complexities of slide rules, abacuses, and other mechanical sorts of calculating machines, prior to the Computer age never captured my interest … (I truly appreciate how ingenious they are though)
So, of course I had to check the figures with my calculator and yep, it works!
I printed out a couple of copies of the pdf (linked in the Instructables tutorial) and will go forth and entertain myself for a while playing with them.
