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.

A company called Sonex has a program called Hornet's Nest Research which is developing a DIY kit to build a personal jet aircraft which they call a VVLJ (Very, Very Light Jet). I would suggest it as a budget gift idea -- since they say it ewill only cost as much as a new S-LSA factory-built aircraft, whatever the heck that is -- but they're not taking orders yet.

Below is a video about it that includes some scenes of it flying.
