Possibly in the 90s you saw the British TV show called “The Secret Life of Machines”. It featured maker and cartoonist Tim Hunkin. I hadn’t seen anything about him in years, but he recently started a YouTube channel and started a new series of videos called “The Secret Life of Components”.
Though not ham radio specific, it discusses many things that still may be of interest. Six have been released and they are still being released about 1 per week. Prominently featured are his hand-built arcade/novelty machines.
His Secret Life of Machines shows have been remastered for his YouTube channel.
Though some of the topics might seem elementary, I find I learn something in every episode.
Here is the link to his channel, give it a try:
