In an era of mass-production, its really curious to come across something like this – this French chap makes his own vacuum tubes … from glass and metal – no pre-fabricated parts at all! The skills displayed in this video are just astounding.
I know there are quite a few old car or bike enthusiasts who either make their own parts or buy them from individuals who do. I wonder if that would ever be possible with, say, an early computer – i.e. an enthusiast would be able to have the skills to repair and maintain something based on digital electronics. (Its probably going to be a lot harder with cars of today anyway, as there are already loads of computers in them).
