The Secret Life of Components

If you ask an engineer of a certain age such as myself what one of the influences of learning about technology and how things functioned was in your early years I suspect a lot of them would mention The Secret Life of Machines. Broadcast in the late 80's the show covered how various common machines functioned in terms of their history development and general internal mechanics. It was presented by inventor and artist Tim Hunkin and special effects and roboticist Rex Garrod (who made Brumm and starred in early seasons of Robot wars).
