The use of water as a means to power a vehicle is something that has come about very recently, thanks to some...

For more than 30 years I have used test gardens for the hobby of metal detecting. I have three currently. Two of them are 5 feet square and the third is only 3 feet square. Why use a test garden? A test garden serves several purposes. Foremost for me is learning the sounds of different targets. My first and oldest garden has 20 different targets buried between about 2 to 8 inches deep. It has taught me to distinguish sounds of iron objects shallow and deeper, aluminum targets ranging from pencil erasers, gum wrappers and various pull tabs. I have learned how to distinguish old nickels, Indian Head cents, war nickels as well as the pesky zinc pennies. Practicing with all my detectors and various coil...

Bring back, that winning feelin Woah, that winning feelin Bring back that winning feelin Cause it's gone,gone,gone wooooooh - with apologies to the Righteous Brothers As a baseball guy, I like to watch other sports for tips on baseball coaching, mental toughness, and confidence. I watched Apollo Ono win the 500m short track speed skating gold in the last Winter Olympics. I could see the electricity rocket through his system after he crossed the line. Fists clenched, arm muscles fired, and a primal yell erupting from just above that ridiculous patch of hair on his chin. We can only imagine what that winning feelin is like. But you know, that's not so bad. Our imagination is extremely powerful. I'll...

Watch is an instrument of fine precision with a primary aim of telling time. However, over the years, besides its function of exhibiting time and date, the designer watch has turned into an investment, masterfully crafted and made of materials like silver, platinum, gold and even encrusted with diamonds. Many luxury watches, especially the ones manufactured by the world famous Swiss watchmakers are treated like designer wear and fine art, to be treasured and valued for generations. In fact, if you look after them well and keep them in pristine working order, their values increase exponentially over the years. The manufacturers therefore consider their designer watches to be in high estimation and...

When beginning, expanding, or integrating your hobby collection, selecting compatible sizes can be confusing. With such a wide range of hobbies and scales, how can you fit together several different genres to create interest? Each hobby category has popular scales and many scales have evolved since prewar years scaling both up and down with precision from 1:1000 up to a large scale of 1:12. My grandfather for example artfully welded together a model train that we could ride in probably in a scale of about 1:7. By exploring the ranges from 1:12 to 1:220 we will cover most of the popular hobby genres. Much like electrical standards, there is not a universal worldwide hobby standard. For example, if...

In the news: One of Australia's biggest selling cars, the Holden Commodore is going to be made available in the US and that is according to General Motors' worldwide head of product development Bob Lutz during a press conference held at the Detroit Motor Show.

Are you familiar with the concept of booking a plane ticket for a trip, then arriving at the airport and being told that you cannot board the flight since it is full? How is that possible if you have booked and paid for your ticket? Welcome to the world of overselling. Everyone oversells - from the air travel companies to the cell phone operators. Overselling is a business model where the business sells more of a resource than they actually have to a group of customers since they know that a large percentage of these customers will never use 100% of the resource. For example: Airplane companies regularly overbook their flights since they know that not everyone will pitch for the flight. In this way...

Over the past 100 years several methods of controlling electric model trains have developed. The first and simplest method was the use a simple variable transformer as introduced by Lionel in 1906 to lower the Alternating Current [AC] voltage from the wall to a lower, safer value and allow the user to control the speed of a model electric train by changing the amount of AC power applied to the track. In the 1920's, Lionel included remote control reversing switches to allow the user to control the direction of the model train. When Direct Current [DC] powered trains with permanent magnet motors were introduced, a different standard was developed for most two rail train tracks where the direction of...

The Realization of a Dream Since I was probably old enough to hold a transmitter in my tiny hands, I have been an avid fan of radio control hobbies. As a kid growing up, I mostly tinkered with R/C cars and trucks. But almost 20 years ago, as I was nearing the end of my teens, I got an itch to start flying. Actually, I wanted to buy an ultralight aircraft, but not having an extra $10,000 put a hold on that idea. I would need a substitute that was more economical for a young man of my age. Not sure where this new venture would take me, I headed to my local hobby shop to buy my first R/C plane. Upon entering the hobby shop, I was overwhelmed with choices. How many channels, what size engine, what type...

As most remote control airplane hobbyists know one of the key elements to provide a good flight distance for their plane is that of the airplane engine. While you may think that you need to have just any old airplane engine installed, you will be far off the mark. There are two types of model airplane engines that can be installed. These are the 2 stroke and the 4 stroke engines. These engines are also referred to as 2 cycle engines and 4 cycle engines. The engine firing cycle is not the only difference to be found in model airplane engines. You have the physical appearance and the engine size to be looked at too. In the physical look the 2 stroke is the easier to find and cheaper engine type. These...

An American gamer walking into a Japanese arcade would probably find themselves quite confused. At first glance, everything appears as it should be; Flashing screens, deafening sounds, and a token machine in the corner, waiting for your cash. After one converts their bills into the ubiquitous golden funny money, tokens, they may notice something has gone awry: The games they're so used to are nowhere to be found. There isn't a single Centipede machine! In its place, however, there is a game in which the player can take the place of a percussionist in a virtual band. In fact, not only are the games ifferent in theme, but many of them don't even have a joystick, the staple control scheme Americans...

Euclid's parallel postulate, in its modern reformulation, holds that, on a plane, given a line and a point not on the line, only one line can be drawn through the point parallel to the line. Gerolamo Saccheri (1667-1733) brilliantly attempted to prove this through a reductio ad absurdum argument. There were two ways to contradict the postulate: space could have 1) no parallel lines (straight lines in a plane will always meet if extended far enough), or 2) multiple straight lines through a given point parallel to a given line in the plane. These become non-Euclidean axioms. Saccheri convincingly achieved his reductio for the first possibility with the innocent assumption that straight lines are...

There are many different services offered in two way radio communications. Each service has its own purpose. Among the basic two way communication services are Citizens band radio operators, Amateur radio, Aeronautical radio and the general mobile radio service. In the private land mobile radio services public safety radio, special emergency radio and industrial radio are included. The citizens band radio operates at specific Megahertz, amplitude modulated or single sideband using shared assigned channels.

Genuine basketball enthusiasts are aware of the significant role played by Wilt Chamberlain in the sport. If you wish to be able to have more fun with your radio controlled cars, knowing the history of RC cars will enable you to better appreciate what you have now. Tamiya Goes First This Japanese toy company was better known for producing plastic or die cast toys. In 1976, however, Tamiya was the first to produce toy cars that were defined as "suitable" for remote control. The prototypes of RC cars were crudely built, but they still sold rapidly. Afterwards, Tamiya was able to improve and innovate by focusing less on scaling and more on the toys' radio control feature. The new RC cars produced by...

When you step into the gym for the first time, it can be overwhelming to see the variety of machines for you to choose from. How do you tell which machine is the best one to meet your needs? The smartest thing to do is to ask an employee or arrange for a one-time session with one of the gym's personal trainers so that you can walk around and get a feel for the gym and understand the purpose of each machine. Using exercise machines as part of your regular workout schedule can be a fantastic way to mix things up and challenge your muscles so they don't get accustomed to the same thing. You can also use machines like rowers and treadmills to get in your aerobic exercise and cut down on stress on the...

It's a bird. It's a plane. It's -- a flying car? Not since the red-lettered, blue bomber buzzed over Metropolis has such a fantasy captured the imagination of so many. In spite of our fascination with the concept, making a vehicle that can be certified by the FAA as airworthy, and can be legally driven on highways, is a complicated task. So complicated in fact, that as much as the idea of a flying car has been around for over half a century, no one has yet to crack through the many blocks in the way of it's advancement. Of course this does not stop many engineers and companies from trying. There are some dedicated and highly resourceful people beginning and in some cases nearing completion on the...
