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…]

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.
