Do or Diode

Diode lasers may vie with LEDs for lighting supremacy

It’s not just BMW with laser headlights. But the higher efficiency is tempting.

Little research had been done on diode lasers for lighting because of a widespread assumption that human eyes would find laser-based white light unpleasant. It would comprise four extremely narrow-band wavelengths—blue, red, green, and yellow—and would be very different from sunlight, for example, which blends a wide spectrum of wavelengths with no gaps in between. Diode laser light is also ten times narrower than that emitted by LEDs

Not sure if the arm-wave is just to be cute or if it’s programmed in to help locate the biker when it’s not moving, e.g. if it got stuck somewhere or lost the signal.

You Can Run But You Can't Hide

We present the Throwable Panoramic Ball Camera which captures a full spherical panorama when thrown into the air. At the peak of its flight, which is determined using an accelerometer, a full panoramic image is captured by 36 mobile phone camera modules.

Neat idea, though the “you can see what’s behind you” gave me a creepy 70’s/80’s horror flick vibe. The call is coming from inside the ball!

Going On and On and On About Archaeology

Tiny drone helps reveal ancient royal burial sites

The machine tested in a remote area in Russia called Tuekta was a four-propeller “quadrocopter”: the battery-powered Microdrone md4-200. The fact it is small — the axis of its rotors is about 27 inches (70 cm) — and weighs about 35 ounces (1,000 grams) made it easy to transport, and researchers said it was very easy to fly, stabilizing itself constantly and keeping at a given height and position unless ordered to do otherwise. The engine also generated almost no vibrations, they added, so that photographs taken from the camera mounted under it were relatively sharp. Depending on the wind, temperature and its payload, the drone’s maximum flight time is about 20 minutes.

Failure is Not an Option

Neal Stephenson: Innovation Starvation

Innovation can’t happen without accepting the risk that it might fail. The vast and radical innovations of the mid-20th century took place in a world that, in retrospect, looks insanely dangerous and unstable. Possible outcomes that the modern mind identifies as serious risks might not have been taken seriously—supposing they were noticed at all—by people habituated to the Depression, the World Wars, and the Cold War, in times when seat belts, antibiotics, and many vaccines did not exist. Competition between the Western democracies and the communist powers obliged the former to push their scientists and engineers to the limits of what they could imagine and supplied a sort of safety net in the event that their initial efforts did not pay off. A grizzled NASA veteran once told me that the Apollo moon landings were communism’s greatest achievement.

In the pre-net era, managers were forced to make decisions based on what they knew to be limited information. Today, by contrast, data flows to managers in real time from countless sources that could not even be imagined a couple of generations ago, and powerful computers process, organize, and display the data in ways that are as far beyond the hand-drawn graph-paper plots of my youth as modern video games are to tic-tac-toe. In a world where decision-makers are so close to being omniscient, it’s easy to see risk as a quaint artifact of a primitive and dangerous past.

Work begins on Babbage’s Analytical Engine

Work has gotten underway on Plan 28, a project to create Charles Babbage’s Analytical Engine, the never-built successor to the Difference Engine. The Analytical Engine was to have been a general purpose computer, and Ada Lovelace designed the first-ever programming language to run on it. Many factors led to its never being completed — the state of the art in precision engineering in Babbage’s day, finance woes, and so forth.
