Popular Mechanics covers

Popular Mechanics, first published in 1902, is a magazine that focuses on science, technology, machines, DIY projects, cars, planes, rockets, tools and the like. At one time it was widely read, but as with most periodicals, the internet has cut into its domain. It is still published. Its articles about future cutting edge technology were frequently ridiculous, and from the looks of things that hasn't changed.

These images of covers from the 20th century are from the Internet Archive. There are many more covers in their archive.

The inner workings of a gumball machine

Mysteries of a clicky pen and other things

Regular readers will know that I am a sucker for the complexities of mundane things. Jared Owen's YouTube channel has a number of 3-D animations showing the inner workings of common devices. His explanations are clear and simple to follow. I've selected three of them: the clicky pen, window blinds and an oscillating fan. There are more at his link.

Machines to Raise Water

Models of ancient machines to raise water from the days before powered pumps. I wonder if they all got off the drawing board? Certainly, those that got built must have been nightmares to maintain.

From Visual Education Project which has a number of other ancient machines as well as entertaining perpetual motion machine attempts.
