Next book edition almost done

Eleven days ago, I said

Now all I have to do for the next release of the book is do the standard final checks (page breaks, spell checks, and URL checks).  This will probably take me another week.

I have now gotten the page breaks fixed and checked all the URLs (only 8 of the 215 distinct URLs needed fixing).  I last checked them about a year ago, so that is a link-rot rate of only 4%/year (a half-life of about 18 years).  In the process of fixing the page breaks, I noticed and fixed a few minor typos, as well as tightening the text in a couple of places (to improve the page breaks).  I found one instance of “the the” with my tandem-word checks (probably introduced since the last released edition).

I still have to do the spell checks.

I did release one new video last night: https://youtu.be/vLece-VKfkQ, which talks about providing a constant current for electroplating (see the post Controlling current if you don’t want to waste time watching an 11-minute video).
