How to Save Power and Lower Your Electric Bill

!: How to Save Power and Lower Your Electric Bill

As energy costs continue to soar, many of us are looking for ways to lower electric bills. Also, as more and more of us are becoming conscious of the environment, we would like to find ways to save power simply to reduce damage power consumption does to the environment. The good news is that there are many ways to reduce electric bills and save power.

First, consider the obvious ways to lower electric bill totals in your home. For instance, if you are not in a room, turn off the light. Turning off a light in your home will save hundreds of watts of power consumption each day. Also, eliminate any lights that are not really needed in your home.

Another way to reduce electric bill amounts for your household is to raise the temperature on your thermostat when the air conditioner is running. In the winter, lower the temperature if your heat is electric. This will cause the air conditioner and furnace to run less often, thus saving you money on your electric bill. Statistics show that every degree you change the temperature will create up to a 3% change in energy costs. A couple of degrees will not likely change how comfortable you feel in your home, but they will make a big difference in your attempt to save power.

Now, there are also some helpful devices you can use to save power in your home. First, replace your incandescent light bulbs with the compact fluorescent bulbs you have been seeing. Yes, these bulbs cost a lot more than their incandescent counterparts, but they also last much, much longer. In fact, they last around 10 to 13 times longer than regular light bulbs. Additionally, they use around 1/3 as much electricity as regular bulbs. They will easily pay for themselves over a year as you notice that they reduce electric bill totals each month that you use them.

Another device you can install in your home to save power is the Power Save 1200. The Power Save 1200 will lower electric bill amounts by reducing the amount of power that is wasted by some of the appliances in your home. Many appliances, such as air conditioners, freezers, washer, vacuums, and fans, use inductive motors. These motors ask for electricity from the transformer every time they need to run. This process creates heat in the motors and the wiring. This heat is actually wasted energy, because it is created by electricity. The Power Save 1200 will store electricity in the home and release it to these motors when they are ready to run. This eliminates the heat in the motors and the wires, which can reduce electric bill totals as much as 25%.

Another device to use to save power is an electronic thermostat. How many times have you left home, only to remember that you forgot to turn the thermostat down or up, depending on the season? An electronic thermostat can be preprogrammed to change the temperature after you have left for work, and then change it again just before you come home. Also, it can lower or raise the temperature after you have gone to sleep at night, and then change it back around the time you need to wake up. This will save you substantial amounts of power by not wasting energy on heating or cooling your home when you do not need it to be heated or cooled.

While we are all facing higher electric bills than ever before, being proactive and taking these steps to save power can help. You can reduce electric bill amounts by utilizing a little common sense and a few new pieces of technology. The ability to save money and power is there, but it's up to you to do something about it in your home.

Model Train Signal Cost Got You Down? Make Your Own

!: Model Train Signal Cost Got You Down? Make Your Own

A model train display just does not seem complete without the addition of signals. Unfortunately, the cost of such signals can be very prohibitive for the standard model builder. If this is the case for you then why not just build your own? You can pick up the parts as you have a bit of extra money and then when you have them all you can assemble and install them onto your display.

As an example for this article we will use an H0 scale model. At the end you will find a list of necessary supplies to build this particular setup. One warning: if you are just getting into model train building and have very little experience in working with electronic components then this article is not for you unless you want to take the time to learn a bit more about the subject before you get started.

The first thing that you would need to do is to create a base for your signal. A piece of .080" styrene will work for this size model. Cut your base out and set it aside. Now you will cut your stack base to go on the top of this. As you cut out your pieces you stack them one on top of the other. These pieces should be 4'x6' in size and should stack until about 6' in height. The next step is to add a piece of 3' square styrene with the edges beveled off to the top of this stack. Once you have all pieces cut you will cement them together along with the base itself.

Once thing you might want to do for ease of use is to sand any sharp edges off of the stack and smooth it out before you cement it to the base. When you do add it you need to make sure and center it properly. Now you are ready to cut a door for your signal. Use a piece of .020" styrene that is 3' square and cement it to the side of the base that faces away from your track. You can also add little pieces of styrene as hinges and a piece of .015" brass wire will work perfect as a door latch.

The next step is to drill a hole through your stack. Make sure it is centered in the middle of the 3' piece of styrene and use a #22 drill. If you go too fast you will melt the styrene so go slow and take your time. Solder your 1/8" and 5/32" pieces of brass tubing together. The 1/8" piece should be just inside the top of the 5/32" piece when you solder it. Slide the assembly through your stack until only a small bit of the large tubing is showing out the top of the stack base. The bottom needs to be just long enough to penetrate your table display. The top pole should be cut off to 20' in H0 scale. If you choose you can add a styrene point to the top of the pole.

Next you need to cut a piece of the 7/32" brass tubing at a 30 to 45 degree angle and leave it about 1/4" long. The square cut end of the tube needs to be inserted into the center of the #10 washer. While your LED may have to be slightly filed down for a good fit it should then fit into the center of this assembly which makes up your head. Make sure to glue everything together from the back of the signal. Now you must decide where on your mast you want to mount your signal head or heads if you choose to make more than one.

Use a round file to notch the back side of the mast and then glue the head to the mast. Take and bend one of your LED light's leads so that they touch the mast and solder it into place. Solder a piece of telephone wire to the other lead and run it through the mast via the notch.

At the bottom section of brass tubing underneath your searchlight you need to add another wire that will act as the circuit common for all the heads you have attached. The next part is very important, if you do not connect it correctly it will not work and could be a fire hazard. If you are using 5 volt TTL signal logic you should add a 180 ohm resistor in series with each wire going to an LED. Use a 510 ohm resistor if you are using 12 volt logic. You will need to add the Walthers signal bridge ladder stock on the backside of the signal mast. Also there are many masts that are marked with a letter "A" that you can add via a piece of styrene cut to shape if you so choose.

You can now paint your signal. The head should be black and the rest will be silver. Once you reverse polarity your LEDs will switch between red and green. While your new signal might be a bit larger than scale it should not be noticeably so. Enjoy!

Items needed for this project:180 ohm, 1/4-watt resistors - super glue - styrene glue - Walthers signal ladder stock - .080" styrene plastic - .020" styrene plastic - #36 gauge telephone wire - 1/8" O.D. Brass tubing - 5/32" O.D. Brass tubing - 7/32" O.D. Brass tubing - T-1 size bi-color LED (red/green dual lead) - #10 S.A.E. Steel-zinc washers

How To Light A Doll House

!: How To Light A Doll House

Doll house lighting is much easier than most people think. Many new collectors are daunted by the task but there are many dolls house wiring kits that make the job very easy and even a novice can light a dolls house.

You should start planning your doll house lighting even before you build your house. The reason for this is your dolls house will look it's best if you can disguise the wires that run to the electric lights by cutting grooves in the floor's of your dolls house to run the wires along and this is easiest to do while the dolls house is unbuilt.

Step one when you get your dolls house should be to start planning your doll house lighting.

Step 1 Decide on the location of all the lights in your dolls house. Will they be on the ceiling, walls, free standing or table lights? You don't have to purchase all the lights at this point but you need to decide on the quantity you will be using and where they will be situated. The quantity of lights you use determines what transformer and socket board you use for your doll house lighting.

Step 2 One you have decided on the lights for your dolls house you are ready to get your transformer and wiring. To determine what transformer you need count up the number of bulbs that will be used in your dolls house lighting. Remember that this is the number of bulbs and not the number of lights, so a three armed tulip light will count as three bulbs.

Step 3 Once you have your socket board it is time to decide where it will be positioned. This is the heart of your doll house lighting system and should be placed somewhere that is easily accessible. For front opening dolls houses the best place is on the back of the house positioned centrally and at the bottom. Once you have done this stick your socket board to the doll house, most boards have adhesive tape attached but you could use double sided tape.

Step 4 Once you have drilled your holes you need to position your lights. If you are using a ceiling roses remember to put these in place first you can stick these down with wood or PVA glue.

Before you can run the wire from the lights through their respective holes and to the socket board you will have to remove the plug. To do this pull out the two pins with a pair of pliers and pull on the wire, the plug should slip off. You can now feed the wire through the holes and along the wire grooves.

Next stick the light in place using its adhesive pad, never use glue. You should also hold the wire in place along its route to the back of the house using masking tape.

Step 5 Plug each light into the socket board and tidy up the wires by masking taping them to the back of the house.

Model Train Hobby Shops - The Hobbyist's Best Choice

!: Model Train Hobby Shops - The Hobbyist's Best Choice

Becoming involved with a hobby which is as challenging as model railroading is can seem overwhelming if you are a beginner. This is a hobby where the novice will quickly discover that there are a number of skill sets which they will have to master, and a new vocabulary directly associated with model trains that is a must to learn. However, if there is a draw to this hobby these are the special qualities about model railroading which make it one of the more popular hobbies in the world.

In fact, the interest in model trains is constantly on the rise, and it captures the attention of people from every walk of life, age, and gender. There is a shared concern among new hobbyist that this is a hobby which can become expensive, and in some ways this has the potential for being true. Holding costs down is frequently an important issue for the inexperienced hobbyist, and one way to accomplish this goal is to make your purchases at a model train hobby shop rather than a regular hobby shop.

If you are determined to shop for your model trains and accessories at your local hobby store the well known caveat "let the buyer beware" certainly applies. It isn't that the employees of these stores aren't well intentioned. The problem is that their knowledge about this hobby is more often than not of a limited nature. After all, they deal with more than one hobby in dealing with their customers, and expecting them to have the ability to answer specific questions about model railroading isn't a reasonable expectation. Remember that the objective of any sales person is to sell as many of their products as they possibly can, and that will in all probability cause you to spend money that you may not have to if you make the mistake of going to a hobby store for you needs.

When you visit a model train hobby shop, you can rely on the fact that you'll be interacting with an employee who has in depth knowledge about model trains, and who is also quite willing to be of assistance.

Before you ever consider buying anything for your future model train layout you should address a other few issues first. Research and good planning is and will continue to be the key to being a successful model railroader, and in knowing this there a few things you should decide before purchasing anything.

For example, are you going to buy a ready made model train set or are you going to build your model train layout from the ground up? If you buy a ready made kit and you have future plans for expanding your layout you'll encounter some troubling problems. It is true that your kit may have everything you'll need to get started but when you decide to expand, one of the first things you may discover is that your transformer doesn't have the ability to power your trains. Although it may have been unintentional, you just set yourself up to incur an additional expense. The problem here is that advanced transformers are not inexpensive. Additionally, you may be planning a model train layout that is entirely to big, both for the space you have available and your budget.

These are just two of the problems that you may end up dealing with and both will cost you more money. The best advice is to do thorough research before committing to anything related to your model train layout, and when your satisfied with the results of your efforts, it is then time to visit a model train hobby shop. At the very least, even if your sales person is very knowledgeable, you'll also be armed with the knowledge that will help you make the best decisions for your initial purchases.

Linear Power VS Switching Power Supplies

!: Linear Power VS Switching Power Supplies

Choosing a power supply is one of the most important steps when building a customized computer. Since the building of customized computers have risen in popularity due largely to the gaming community as well as computer enthusiasts, it is important to understand how to choose a power supply for the ensuing stroke of genius that is created as a portal to the Internet. Without the heartbeat of electricity, and a steady stream that can handle the power built into a custom computer, even the best designed customized computers fall into the land of permanent rest.

Linear and switching power supplies are options as well as the uninterrupted power supply variety. The choice comes down to what you need for your particular computer and the amount of voltage necessary to run your new source of pride and joy.

Linear power supply is seldom the answer for customized computer. These types of energy supply require very large transformers and are extremely heavy. Unless you are a body building champion with a need to prove yourself, linear power is probably not what you want at approximately one pound per ampere. Add to that the necessity of large heat sinks to dissipate energy loss and an efficiency of about 50%, linear power options are simply too cumbersome and inefficient to meet the needs of most home computer building purposes.

Most enthusiasts choose something in the switching power supplies category since they want a computer-not a weight lifting championship. There is higher production costs involved, but these options are lighter weight and smaller-meaning they will fit in your house. Another advantage is that these power supplies are about 70-90% efficient. Since the efficient running of your computer is generally the goal, this increase in efficiency has a big pull for power supply choice.

While this sounds confusing, it really isn't. Switching power supplies use AC voltage-120V or 220V-which is generally what a house is equipped to handle anyway. There isn't any sophisticated equipment that you have to have wired into your house for its use. The main difference in the power supply needed comes in choosing the power factor correction and not in changing your plugs and house wiring to be able to use a switching power supply.

You may, however, have to increase your breaker capacity if you already have too much depending upon them when you plug your newest creation in, but that is to be expected with anything you add that uses the electrical circuits available in the average home. Another necessity is protecting your computer from power surges with a properly designed surge protector. Otherwise, there isn't much you have to do to prepare for your power supply choice.

If you are still confused, simply call up your local computer store and ask. Many of the employees in the stores can help you decide and find what you need. Always consider asking a professional computer tech who has experiencing in networking and other hardware areas of computers for the added security of getting the correct information and helpful recommendations that can make your experience with powering your computer an enjoyable one.

Transformers: How Transformers Work

!: Transformers: How Transformers Work

An Electrical transformer is an electrical device which takes voltage from one level to another, usually from a higher voltage to a lower voltage.

The power transformer works by applying the principle of magnetic induction between coils to covert voltage and current levels. With it, voltage can be easily multiplied or divided, making long distance transmission of power a reality. A step down transformer allows a device that requires a low voltage power supply to operate from a higher one. The electrical step down transformer will take in the high voltage at a low current and puts out a low voltage at a high current. An example of this is your home's doorbell. It runs on 100 VAC, converted to 12 VAC. A transformer that does the opposite is called a step up transformer. An electrical step up transformer increases voltage from primary to secondary - more secondary winding turns than primary winding turns

The voltage transformer transfers electrical energy from one circuit to another through inductivity coupled conductors-the transformer's coils. The power supply from batteries, the kind you buy from Radio Shack, is direct current (DC) rather than alternating current (AC). The term "power supply" is sometimes restricted to those devices that convert some other form of energy into electricity-such as solar power and fuel cells and generators. A more accurate term for devices that convert one form of electric power into another form--such transformers and linear regulators-is a power converter.

Small electrical parts for electrical circuit boards can be found at Radio Shack and online at Mouser Electronics while suppliers like Square D will have parts like electrical switchgear for residential and industrial needs. The electrical converter changes the voltage of an electrical power source.

An electronic symbol is a pictogram used to represent various electrical parts. For the most part these electrical symbols are internationally standardized.

An electrical generator is a device that converts mechanical energy into electrical energy. The reverse conversion of electrical energy into mechanical energy is done by a motor. Motors and electrical generators are very similar. The generator will force electrons into its windings to flow through the external electrical circuit. The source of the mechanical energy may be reciprocating or turbine steam engine, water falling through a turbine or water wheel, an internal combustion engine, a wind turbine, a hand, compressed air or any other source for the mechanical energy.

The most common power conversion is from AC to DC. The Electrical adapter and the AC adapter are power supplies that will perform this type of conversion. Whether or not the unit that is using the electrical adapter is plugged in; the transformer has a magnetic field continuously present and cannot be turned off unless unplugged. Because they consume standby power, they are known as "electricity vampires" and may be plugged into a power strip to allow turning them off.
