Perhaps you’ve seen the series on the Discovery Channel called How It’s Made. Each 30-minute episode highlights four somewhat common products. Some of the more interesting (to me) items have been guitars, optical lenses and stamps. While these features are created for a general audience, they are interesting and provide a unique view into how these items are manufactured.
I recently saw an episode that explained how a microphone is made. The segment was created at the Neumann manufacturing facility and showed a U87 being built.
If you missed the episode, it appears to be on season 11 episode 7. I found it on Youtube.
Have you seen an interesting segment on this or another episode? Maybe another program?
