Learning About Wireless Charging


Picture a world with no tangled charging cables, the ability to charge mobile devices almost anywhere, and wireless kitchen appliances. That probably sounds like something out of a Jetsons cartoon, but it’s a world we’re moving toward at increasing speed. The idea of wireless power is not a new one. Nikola Tesla experimented with wireless power as early as the 1880s1, and Oral-B’s rechargeable toothbrushes have used wireless inductive charging since the early 1990s.2

There’s a lot of science behind wireless charging, also called inductive charging, but I’ll try to explain the basics as simply as I can. If you don’t care how it works, go ahead and skip to the next paragraph. In essence, an electromagnetic field is used to transfer energy between two objects. A charging pad has a transmission coil that converts a regular alternating current into an electromagnetic field. The receiving device has a receiving coil that converts the electromagnetic energy back into electrical current that the device uses to charge its battery. [Read more…]

Is SanDisk’s 512 GB SD Card Vulnerable?

First, a brief history of SD Cards.

SD card

Way back in 1999 SanDisk, Toshiba and Panasonic launched a new player in the memory card game. These SD cards were based on an earlier card format, called MultiMedia Cards (MMC), created by SanDisk and Siemens a few years earlier. Today, despite their high level of market saturation, many people aren’t aware that SD stands for Secure Digital, and even fewer people are aware that the word “secure” in the name refers to its ability to store encrypted music data. The original incarnation of SD cards had a storage capacity that maxed out at 2 gigabytes. [Read more…]

Internet Data Traffic is Growing by Leaps and Bounds


Every second, there are approximately 23,532 gigabytes of Internet traffic.1 When I do the math, that comes out to approximately 2 exabytes (2,033,164,800 gigabytes) every day. To give that a little perspective, that’s double the total amount of Internet traffic back in 2000.2 A large part of that leap in usage is due to the rise in data traffic, especially high definition (HD) content, like video.

Learn About Smart Home Technology


One of the new trends in technology is the “smart home.” While the industry is still mostly in the “early adopter” phase, prices are coming down and availability is going up. Most of the smart home technology falls into one of five categories: home access, appliances, lighting and climate control, home communications, and home entertainment. [Read more…]

Quantum Computing in the Cloud


Because it’s based on quantum mechanics, really understanding quantum computing is generally a little bit beyond the average Joe. Even the basic explanation gets complicated: while traditional, digital computers store information in binary digits, or bits, which are always in one of two defined states (0 or 1), quantum computers use subatomic superposition and entanglement to allow their quantum bits, or qubits, to be in more than one state simultaneously (0, 1, or 0 and 1).1 This basically means that a quantum computer can perform operations exponentially more complex than those that can be performed by more traditional computers.

2015 Formula 1 Races to Watch


With the Singapore Grand Prix behind and the Japanese Grand Prix looming, the 2014 Formula 1 World Championship® is heating up. Lewis Hamilton is in the lead by a paltry 3 points with his Mercedes team mate, Nico Rosberg, nipping at his heels.

However, while I’m looking forward to the remaining Formula 1 races of 2014, I’m really excited about the FIA confirming a 20-race calendar for 2015 Formula 1 racing. The FIA (Fédération Internationale de l’Automobile, also known as the International Automobile Federation) is the governing body for Formula 1 racing. With the reintroduction of the Mexican Grand Prix, next year’s season will finish one week later than in 2014, with the finale race taking place in Abu Dhabi the final weekend in November.

Building and Developing Mobile Apps


There are a lot of mobile apps out there. With them, you can do almost anything from learning to play the piano to raising dragons. Each of these apps (and every future app) had to go through the process of being built and developed. If you’ve had an idea for the next big app, I’d like to give you an overview of the process you can probably expect to tackle in order to move forward with building and developing your idea.

Wearable Technology


You don’t have to be the “most connected man in the world” to use wearable technology these days. In our society, there are hundreds of devices that fall into the category of wearable technology. Even watches and headphones are technically wearable tech, but in recent years, we’ve seen a huge surge in both the use and usefulness of different types of wearable technology. I’m not even going to attempt to make a full list of wearable technology, just discuss a few of the types that have increased in common usage (and a few that are just plain interesting).

No-Touch Interfaces


When you hear the term “no-touch interface”, you probably think of the computers in movies like Iron Man or Minority Report. You may have even heard about paraplegics typing with their eye movements or moving machines with their brain. However, there are three fairly common no-touch interfaces currently available, and I’ll bet you’ve probably used at least one of them. [Read more…]
