Although there are certainly different types of speakers in terms of size, quality and price, essentially the components are pretty similar. These are the basics: The Enclosure: This is the part that you notice first. The enclosure, also known as “the Box” can be made of various materials including wood or plastic. This houses all the components of your speaker.  You decision on which one to buy will often be based on visual elements at this point. Crossover: This part involves circuits that direct the incoming audio signals toward the drivers. High frequencies are sent to the “tweeter” and low frequencies are sent to the “woofer”. Some speakers also contain a mid-range driver, which as the name suggests, plays the mid-range frequencies. Drivers: Have the function of creating sound waves. Also known as the “tweeter”, “woofer” & “mid-range”, every speaker uses a different configuration of drivers. Whether a woofer or a tweeter, all drivers comprise of an electromagnetic voice co

For all of you James Bond fans out there, this is not your typical wrist watch, this is something that you’ve always wanted: sports watch with built in camera. So if you want to feel like you want to embark on your very own secret agent career, this watch could be a start. When you first look at it, it looks like a standard sports watch, with its simple but sports looking design. But if you look  a bit closer you can see a small spy camera hiding. It’s perfect for all your spy missions because it has all sorts of interesting features. First of all it’s a sports watch, a camcorder, camera and a recorder all in one single device but it can work as PC web camera as well. It has built in rechargeable Li-ion battery and it can be connected and charged via USB cable. It can take images in 3264 x 2448 pixels resolution which just enough. For color videos that resolution is bit smaller and it goes around 1280 x 960 pixels. It’s perfect for all sorts of recordings because built in camera a

PlanetSolar - The Largest Solar-Powered Vessel in the World Built at the Knierim Yacht Club in Kiel in northern Germany, PlanetSolar is a vessels powered by photovoltaic solar panels that cover about 500 square meters of the boat's surface, making the catamaran the biggest solar-powered vessel in the world. It is worth mentioning that the boat is 31m long and 15m wide and cost 18 million euros to make (about $24.4 million). The 60-ton PlanetSolar has an average speed of 8knots (9mph or 15km/h). The solar panels installed on the vessel will be able to collect 103.4kW of energy that will power the engine. It is expected to be launched waterside in March and the sea trials will take place between June and September. In 2011, Raphael Domjan, a 38 year old Swiss, together with Gerard d'Aboville from France, who is the first one to row the Atlantic Ocean, are going to take the solar-powered boat on a journey around the world. The goal is to show that it is possible

The helmet used by the U.S. military has changed dramatically over the years.In World War I, the M1917/M1917A1 helmets,They were replaced in 1941 by the M-1 "steel pot," the standard-issue helmet in World War II, the Korean conflict and throughout the Vietnam War. By the 1980s, U.S. military helmets had evolved into a one-piece structure composed of multiple layers of Kevlar  29 ballistic fiber. The helmet of the near future, however, may contain something more than extra protection from flying shrapnel. An Arizona State University researcher, working under a grant from the U.S. Defense Advanced Research Projects Agency (DARPA), is trying to develop a military helmet equipped with technology to regulate soldiers' brains. The technology is transcranial pulsed ultrasound, which delivers high-frequency sound waves to specific regions of the brain. Under the influence of these sound waves, neurons send impulses to their targets, exerting control over them. On the ba

More than you'd think! In 1908 Henry Ford’s foreman, William Klann, visited a slaughterhouse seeing the ‘disassembly line’. He cleverly uses the same principles in reverse to create an ‘assembly’ line for the building of cars. The idea is to have the parts flow on a line to the workers who are stationary, rather than have the workers travel to each  station to complete the cars. Henry Ford's perfection of the assembly line in 1913, allows what used to take 12.5 man hours to be reduced to 1 hour and 33 minutes. This allows Ford to make cars faster and cheaper than ever before, producing vehicles that were affordable enough to make motor car travel a possibility for everyone, not just the wealthy.

Scientists are one step closer to completing robotic arms that are controlled by the brain. A device that would allow paralyzed people to use their thoughts to move robotic limbs fluidly and realistically is now one step closer to reality. A team of scientists from Harvard, MIT and Massachusetts General Hospital led by Ziv Williams have found two groups of cells in one area of the monkey brain th at allow the animals to remember a sequence of two movements at once. The team was then able to program a computer to interpret those brain patterns, in turn moving a cursor on a screen in the planned sequence. The development is an improvement over current brain-machine interfaces, which focus on translating a single thought into a single movement in an external device.
