       | served by the rather old CMS running an equally old PHP.

       | The classic on this: "A Boy and a Battery", by Yates. (1959

       | There's a whole series, "A Boy and a Motor", etc., all the way up
       | to how to build your own model railroad from scrap, if you have
       | the skills of a master machinist. Plus "Atomic Experiments for
       | Boys". Really.
       | 
       | The Internet Archive has many of these.[2] "Shop Practice for
       | Home Mechanics" is still useful, teaching how to do basic
       | metalwork with simple hand tools. They cover lathe work, all the
       | way up to how to make a crankshaft.
       | 
       | All this dates from an era before the availability of unlimited
       | entertainment for timepass.
