If you ask those of us who grew up somewhere in the 1950s to 1970s what our car would be like in the year 2020, we might have described an Avrocar. This top secret vehicle from Canadian Avro was part hovercraft and part jet-powered vertical takeoff vehicle. There were two prototypes actually made and [Real Engineering] has a short video on how the prototypes worked, how the real design might have worked, and even has a lot of footage of the actual devices. You can see the video below.
The designer, [Jack Frost], experimented with ground effect and the Coanda effect. The Canadian branch of Avro, a British company, worked with the U.S. military and if you look at it, you wonder how many UFO sightings it caused. Nothing like a flying disk 18 feet in diameter going over your backyard to make you call the newspapers. On second thought, it probably never got enough altitude for that to happen.

The BBC, as the British national broadcaster for so many decades, now finds itself also performing the function of keeper of a significant part of the collective national memory. Thus they have an unrivaled resource of quality film and audio recordings on hand for when they look back on the anniversary of a particular story, and the retrospectives they create from them can make for a particularly fascinating read.
This week has seen the fiftieth anniversary of a very unusual event, the day six flying saucers were found to have crash-landed in a straight line across the width of Southern England. It was as though a formation of invaders had entered the atmosphere in a manoeuvre gone wrong, and maintained their relative positions as they hurtled towards the unsuspecting countryside.
Except of course, there were no aliens, and there were no flying saucers. Instead there was a particularly resourceful group of apprentices from the Royal Aircraft Establishment at Farnborough, and the saucers were beautifully made fibreglass and metal creations. They contained electronic sound generators to give an alien-sounding beeping noise, and a fermenting mixture of flour and water for an alien-looking ectoplasmic goo should anybody decide to drill into them. The police were called and the RAF were scrambled, and a media frenzy occurred before finally the jolly hoaxters were unmasked. In those simpler times everyone had a good laugh and got on with their lives, while without a doubt now there would have been a full-blown terrorism scare and a biohazard alert over all that flour paste.
A Hackaday writer never admits her age, but this is a story that happened well before the arrival of this particular scribe. We salute and envy these 1960s pranksters, and hope that they went on to do great things. If you are a British resident you can see an accompanying TV report on their southern regional news programme, Inside Out, on BBC One South East and South today at 19:30 BST, or via BBC iPlayer should you miss it.

It’s Sunday evening, and that means Hackaday Links, and that means something crowdfunded. This week it’s UberBlox. It’s a modular construction system based on Al extrusion – basically a modern version of an Erector set. Random musings on the perceived value UberBlox offers in the comments, I’m sure.
[Trevor] sent in something from his Etsy shop. Normally we’d shy away from blatant self-promotion, but this is pretty cool. It’s reproductions of 1960s Lockheed flying saucer plans. We’re not sure if this is nazi moon base/lizard people from the inner earth flying saucer plans or something a little more realistic, but there you go.
3D computer mice exist, as do quadcopters. Here’s the combination. It looks like there’s a good amount of control, and could be used for some aerobatics if you’re cool enough.
Who doesn’t love LED cubes? They’re awesome, but usually limited to one color. Here’s an RGB LED cube. It’s only 4x4x4, but there’s a few animations and a microphone with a beat detection circuit all powered by an ATMega32u4.
A while ago we had a post about a solar powered time lapse rig. Time lapse movies take a while, and the results are finally in.
