Thaere ahve been many such books. In the UK, a lot were published by
Babani Press (they now seem to sell Windows books as well :-(). Also
things like '50 simple LED projects', 'Simple projects using 7400 ICs',
etc (I've probanly mis-remembered thsoe titles).

Presumanlu it used slope detection?

Yes, bitterly. Along with the manuals for the '150 in 1' electronics
kits. Many of the projects used 'clever tricks' and were not a all easy
to understand just why they worked, or how to debug them when they didn't
