Pre-Nixie digital: the amazing world of edge-lit displays

https://www.youtube.com/watch?v=OIATKbSkYxw&feature=youtu.be

Before there were Nixie tubes, there were edge-lit displays: “Each digit panel has a tiny incandescent lamp associated with it that lights when that the numeral on the panel is to be displayed. When the tiny lamp corresponding to a given digit panel lights, the light is injected into the edge of the plastic panel. The engraved area in the plastic causes interference with the light as it travels through the plastic, and some light is refracted out through the plane of the panel, causing the engraved dots making up the digit to light up with a white glow. The resulting digits look much like the fully formed numerals in a Nixie tube, except rather than an orange glow, the Canon display digits give off a cool white glow like that of an incandescent light bulb.”

Woman’s headphones explode while traveling on airplane

An unidentified woman flying from Beijing to Melbourne was sleeping on the plane, listening to music on her headphones, when she heard a loud explosion. Then her face began to burn, according to the Australian Transport Safety Bureau.

About two hours into the flight while sleeping, the passenger heard a loud explosion. “As I went to turn around I felt burning on my face,” she said. “I just grabbed my face which caused the headphones to go around my neck.

“I continued to feel burning so I grabbed them off and threw them on the floor. They were sparking and had small amounts of fire.

“As I went to stamp my foot on them the flight attendants were already there with a bucket of water to pour on them. They put them into the bucket at the rear of the plane.” The battery and cover were both melted and stuck to the floor of the aircraft.

The burning headphones – and their toxic fumes and smoke – had passengers coughing throughout the rest of the flight. They left the woman with burns and blisters.

And the cause of the explosion? Batteries of course – nothing new these days. Click here for the full story.

Hand stuck to freezing metal? Urinate on it.

The US Navy’s Polar Manual from 1965 may come in handy during this week’s blizzards. From the list of “Polar Do’s And Don’t’s”:

1. Dares are neither offered nor taken. Necessary risks are bad enough.

25. Heavy and bulky polar clothing makes you clumsy and prone to accidents from lack of normal agility. Plan NOT to have an accident.

26. Do not touch cold metal with moist, bare hands. If you should inadvertently stick a hand to cold metal, urinate on the metal to warm it and save some inches of skin. If you stick both hands, you’d better have a friend along.

Rolls of Lego tape!

Nimuno Loops are rolls of Lego-compatible adhesive tape. Genius idea and no surprise that they’ve blown wayyyyyy past their Indiegogo goal to manufacture the stuff.

Imagine being able to build around corners, on curved surfaces, or even onto the sides of that sailing ship you’ve just spent hours building. You forgot to engineer a point of attachment for that sweet dinosaur-smashing cannon? No problem. Snip a length of Nimuno Loops, stick it on the hull, mount your cannon and be on yarr way.

How to overcome shyness

The School of Life has a video to help people overcome shyness.

Shyness is based on a set of ideas about the world that are eminently amenable to change through a process of reason because they are founded on some touchingly malleable errors of thought, Shyness is rooted in a distinctive way of interpreting strangers.
