Viruses are often known as the invisible enemies that make you weak, but virus expert Julian Tay and Pennsylvania State University engineering professor Gary Settles have discovered a way to see how gas travels when a person coughs in order to find out more about how viruses can spread through the air.
The method the duo uses, Schlieren photography, is not new. It photographs the flow of fluid and is commonly utilized to check the aerodynamics of vehicles in air tunnels. Additional equipment used includes precision optics, a curved mirror, and a razor blade to control how much light passes … Read more
Earlier this week, I mentioned a pouch made for point-and-shoot cameras during my Editor's Office Hours video that I keep attached to my bag strap so I always have a camera handy. I received a couple e-mails about what exactly the product I mentioned is (thanks for watching, BTW), so I figured I'd post something quick about it here on Crave.
There are obviously a ton of small camera pouches out there, but I needed something sturdier and more secure than most. The $17 Digital Pouch DF-404 from Kata is part of the company's Digital Photo Series, … Read more
Generally, camera firmware updates fall into the random, infrequently occurring bug- or compatibility-fix category, and unless you've experienced the issues an update resolves, I suggest against updating your camera. Every now and then, though, an update comes out that--theoretically, at least--affects most or all users. The version 1.1 update for the Nikon D300 falls into this category. Buried among the usual host of minor changes, like "The Highlights playback option has been moved from Display Mode > Basic photo info > Highlights in the playback menu to Display mode > Detailed photo info > Highlights" are … Read more
Here's a really ingenious way to record your cycling stunts. All you need is the old-school bicycle bell that you use to warn pedestrians or freak out your cat.
Jens Almstrom has found out that by removing the upper casing of the bell, there is usually a screw at the bottom chassis, which has the same dimensions used for most tripod sockets. What he did was to simply mount the camera onto that screw, and there you have it--a simple fix to record your journey or stunts with your BMX.
Our advice is to not fumble with the controls … Read more
Shortly after rumors began to surface about a Nintendo DS successor, the company officially announced that the next Nintendo handheld would be called the DSi and will include two bigger screens, two cameras, and would be 12 percent slimmer than the DS lite (at the expense of the Game Boy Advance slot). But perhaps what's most exciting about the DSi is the addition of a DS Store, where you'll be able to download games directly to the device (which will also have an SD slot). For a First Look at the new DSi and its store, watch the … Read more
Sony is in deep trouble. The company has been forced to slash its earnings forecast by 57 percent amid deteriorating economic conditions and its inability to compete more effectively in markets throughout the world.
Of course, Sony will still post a profit--most analysts claim that it'll be about $500 million--but the downturn speaks to Sony's issues and the fact that this once-dominant company has been downgraded to an also-ran in the industry.
Remember the days of Sony dominance? It was a time when the Walkman was on the minds of tech lovers around the world and the PlayStation moniker was held in the highest regard. Sony TVs were everywhere, and the company's ability to capitalize on any market was truly astounding.
But since then, Sony has lost its way. It's no longer a company that can rely on its name to beat other companies to a pulp, and with more competitors realizing how to beat Sony, it has quickly become irrelevant in many markets.
Sony's presence in the digital-camera sector is suspect, and its gaming business, once one of the most profitable departments at the company, has become an embarrassment of epic proportions. Although its PlayStation Portable is expected to beat forecasts, the Playstation 3 has proven to be one of the biggest blunders the company has ever committed.… Read more
