Bose-CineMate-GS-Series-II-Digital-Home-Theater-Speaker-System-0-300x300LED TVs
LED (light-emitting diode) TVs are the most popular TV type on the market, delivering excellent overall picture quality. LED TVs are a great choice for all lighting conditions, especially well-lit rooms.
LCD TVs
LCD (liquid-crystal display) TVs offer quality HD performance, often at very affordable prices. LCD TVs produce bright colors and perform best in well-lit rooms.
Plasma TVs
Plasma display panels (PDPs) deliver superb picture quality with rich, vibrant colors and deep blacks. Plasmas are exceptional at displaying fast-moving action with minimal blurring. They perform best in dark or low-lit rooms and offer wider viewing angles than most LED or LCD TVs.

OLED TVs
OLED (organic light-emitting diode) TVs offer an extremely high degree of color accuracy, great contrast, wide viewing angles and a picture that is virtually blur-free. Each one of the millions of pixels is individually illuminated, producing true blacks and a brilliant range of colors.
The Benefits of OLED TVs:
Color Accuracy — OLED TVs have the ability to recreate every color in the visible spectrum. The resulting colors are richer and truer to life.
Contrast — OLED TVs create black areas by completely shutting off, something no other modern TV technology can do. Their inherent high brightness also produces pristine whites.
Fast Switching — OLED TVs have extremely fast refresh rates for blur-free action sequences.
Wide Viewing Angles — The high brightness and self-illumination of OLED displays translate to an extremely wide viewing angle. Simply put, the image remains brilliant even as you move away from the direct center of the screen.
Low Power Consumption — Since they produce their own light and require no backlighting, OLED TVs are extremely efficient.
Dimensions — OLED TVs can be made very thin and are therefore very lightweight.

9 steps to convert silverlit/airhogs xtwin into a scale model planeair hogs

Air-Hogs-Titan-0-300x3001) Choose your plane
If you are doing this the first time i would recommend doing a simple,two engined propeller plane.
2) Planning
There is no fixed size for the aircraft, but a little bit bigger than the size of the original xtwin is a sensible size for the engines to handle. In your plans you MUST at least have a front and side view of around the same length.
3) The materials
The vital material to have is extruded polystyrene, or depron foam as it is more commonly known.

Air hogs
4) Cutting the parts
Once you’ve printed off the plans, get your depron and with a craft knife cut around the plane templates. Once you have done that, sand down all the wing surfaces with sand paper.
5) The electronics
The electronics on all xtwins are about the same. There are two motors (usually pushers) a receiver with charging port and the battery. The motors can simply be pulled off along with the wires.

6) Putting it together
Firstly, cut a slot about 3 mm wide where shown in the diagram to about halfway down the whole length of the plane on both pieces (as they are going to slot together, the important thing is to put the slots on OPPOSITE SIDES to each other.

7) Test flying
When you do get round to test flying, fly it in a large indoor area or a grass field on a day with very little or no wind.
8) Painting and decals
Spray paint is ideal (although you have to make sure it is either acrylic based or “foam safe” as some spray paints can dissolve the depron foam).
9) Now go out and fly the thing
After you have painted the plane, you are pretty much done

4 keys: Ventilation fans broan ventilation fans

Broan-673-60-CFM-Ceiling-Ventilation-Fan-White-Plastic-Grille-0-300x3001. Find the right airflow rating for room size
All ventilation fans have an airflow rating measured in cubic feet per minute (CFM). To find the CFM rating you need, measure the room to determine the square footage. The Home Ventilating Institute recommends one CFM per square foot of bathroom area, with a minimum of 50 CFM.

2. Choose a noise level you can live with
Noise level is measured in sones. One sone or less is about as loud as a refrigerator running. Three sones is slightly louder than typical office noise. Noise levels for fans range from below 1 sone to as many as 4 sones. Choose a sound level that you can tolerate for at least 15 minutes.

3. Consider fans with extra features
Fans come with many extra features, such as lighting, heaters and automated timers. Some come with a humidistat that will turn the bath fan on and off as the humidity level in the bathroom changes. Avoid fans that turn on and off with the light switch — they are often turned off before the fan has time to work.

4. Find the best ventilation method for your bathroom
The type of fan you choose will most likely be determined by available space and proximity to existing duct systems. Bathroom fans come in a few main types:

Ceiling-mounted fans are installed into the ceiling and vent to the outside through the roof or ducts. This is the most common type of bathroom fan and is best for removing hot, damp air as it rises.

Wall-mounted fans are installed in exterior walls and pull air directly outside. These fans do not need ductwork, but might have a visible register.

Inline fans are installed in the ceiling or wall, but the motor sits between ducts, remotely pulling the air outside. Because the motor is not attached directly to the ceiling, this is a very quiet bathroom fan. These are ideal when there’s not enough space in the ceiling.

4 Tips: Home automation system foscam cameras

3-pack-Foscam-FI8910W-Black-WirelessWired-Pan-Tilt-IPNetwork-Camera-with-9dbi-Antennas-0-300x3001. Follow your heart instead of your head
Forget what you think you know about what home automation can do… Sit in your favorite room and imagine what you’d like to automate: the lights? the temperature? the music? the fireplace? … the options are virtually endless but require a clear slate so that you can create your perfect home canvas.
2. Put on your thinking cap
After you’ve gotten creative, make a list of the home functions (room by room) that you want to control and factor those into the master design. Do you want to manually control the temperature, for example, or would you like a conditional control (like the sunrise or sunset) Perhaps you’d like the system to react to a voice command.
foscam cameras
3. Choose your “brain”
You may need the experts on this one. Now that you’ve complied a list of all that you want your system to do, it’s time to decide on the right technology to facilitate. The “brain” or the main controller for home automation can be handled with hardware, software or a combination of the two – a “hybrid” model. Hardware works best for simple systems with manual controls while software is designed for those with more complex home automation needs (like controlling your security system)
4. Pick your control technologies.
Sadly, people often decide this prematurely – before their needs are clear. Choosing which control technology to use (wired vs wireless, for example) should be done after the needs are established. You have a variety of control technologies, including those that are hard-wired, wireless, Ethernet based, etc.

5 Tips: Tablet ipad air

Apple-iPad-Air-MD786LLB-touchscreen-tablet-iOS-8-1GB-memory-32GB-hard-drive-Wi-Fi-Space-Gray-0-300x3001. Think About How You’ll Use It
Will your tablet be primarily for work, school or personal use? Will it take the place of a laptop, or will you use it in addition to an existing laptop or desktop? Do you want to use your tablet for lots of gaming and movie watching, or is it for more general home use, like browsing the Web or checking e-mail and Facebook?

2. Compare Apps and Operating Systems
One of the first decisions to make is which operating system is right for you. The most common are Android, Windows and, of course, the Apple iOS that powers the iPad and iPad 2. The BlackBerry PlayBook runs QNX, a tablet operating system developed by BlackBerry manufacturer Research in Motion. While iOS is specific only to the iPad and QNX is specific only to the PlayBook, Android and Windows operating systems can be found on tablets from several different manufacturers.

3. Compare features
If you choose to go with an Android or Windows tablet, you’ll want to compare features across the various manufacturers to see how each tablet stacks up. Look at specs like battery life, Wi-Fi versus 3G or 4G access, storage capacity and processing speed, as well as extra features such as cameras and add-on accessories.

ipad air

4. Compare size and appearance
Even if you plan to purchase your tablet online, it’s a good idea to head out to your local Apple store or other electronics retailer. Before you go, give some thought to the tablet size you’re looking for. Do you want the largest screen possible, or do you want a tablet that easily slips into your purse or backpack?

5. Consider price
Before you make your final decision, make sure you’re comparing apples to apples (or Androids to Androids) in terms of storage, processing speed, Internet access and size, since even tablets within the same product line often come in different models and performance levels.

8 Steps: Smoke detectors kidde smoke alarms

Kidde-i12010S-Hardwired-Smoke-Alarm-0-300x3001. Know the types of smoke detectors and their strengths and weaknesses

Ionization alarms work by ionizing the air inside the smoke alarm with trace amounts of a radioactive element, americium 241. Smoke particles entering the ionization chamber disrupt the current, triggering the alarm.

Photoelectric alarms smoke particles entering the detection chamber diffract the light onto a sensor to trigger the alarm. Photoelectric alarms are better at detecting the larger smoke particles from slow, smoldering fires, such as electrical fires or those in bedding, clothing, or upholstery.

Dual-sensor smoke alarms incorporate both ionization and photoelectric sensor components. They are the most costly but provide the best smoke detection for home use.

The air-sampling smoke detector. They are similar to ionization alarms but more sensitive and geared for business and scientific environments.

2. Consider the way the smoke detector is powered. Many smoke detectors run on 9-volt, AA, or AAA batteries, which must be replaced periodically. Some smoke alarms are equipped with lithium batteries designed to last for the 10-year life of the unit.

3. Factor in the size of your house. You should plan to install a smoke alarm in each room of the house, including the basement and attic. Also plan to put a smoke detector in each hallway that leads to a bedroom, as well as in the bedroom itself, and at either end of a stairway.

4. Look for the UL label. Tested and certified by Underwriters Laboratories, Inc.

5. Look for a convenient way to test the smoke detector. Smoke alarms should be tested on a monthly basis to make sure they’re working properly.

6. Look for a unit that’s easy to maintain. Smoke detectors should be vacuumed once a month to remove dirt that can block their sensors

7. Look for the ability to turn off the alarm without disabling the unit.

8. Consider any special needs you may have. Visual alert system for the hearing-impaired.

5 Important features: Webcam logitech webcam

Consumer-Electronic-Products-Logitech-HD-Webcam-C270-720p-Widescreen-Video-Calling-and-Recording-Non-RetailBulk-Packaging-Supply-Store-01.Megapixels – The megapixels are the tiny dots of colour that, when combined, make the resulting visual image. A webcam with more megapixels will result in a clearer more vivid image. Most webcams now will provide a reasonable image quality; the general advice is a webcam that has 320 X 240 or 640 X 480 pixels for a good image. If you have the functionality of HD, consider a webcam of 1280 X 720 pixels.

2.Frame Rate – As the megapixels deal with image and colour vividness, the frame rate is what controls how smooth the video quality is. Frame Rate decides how many images per second are displayed. 30fps (frames per second) is more than suitable for a standard use webcam. Smoother, higher quality moving image should consider a webcam with the capabilities of 60fps.

3.Lens Quality – the lens is the first stage in the video process therefore it is vital that you have the correct lens to cater for your needs. A webcam with a glass lens is much better than one with a plastic lens.

4.Continuous Autofocus – In many scenarios there can be a lot of activity happening during a webcam session, autofocus (AF) enables the webcam to keep you as the main focus rather than diverting to other movements within the frame.

5.Low Light Quality – If you tend to use your webcam during the evening or in low light conditions, the resulting image quality can be very poor. Logitech have developed ‘Right Light’ in some of their webcams. This enables the image quality to be optimised in these poor light conditions.

6 keys: Blood pressure monitors Omron blood pressure monitor

Omron-3-Series-Wrist-Blood-Pressure-Monitor-0-300x300Our most recent tests of blood pressure monitors found many that are worth recommending.

1.Check the fit
For arm models, make sure the blood pressure monitor you choose has a cuff that fits the circumference of your upper arm. Using a cuff that’s the wrong size can result in a bad reading. Most models we tested have two cuffs or a cuff that adjusts to fit most people. Wrist models also adjust to fit most people.

2.Available features
An irregular-heartbeat detector checks for arrhythmias and other abnormalities. (We did not test those features.) A risk-category indicator tells you whether your blood pressure is in the high range. Multiple-user memory allows two or more users to save readings.

3.Cost
The recommended models in the Ratings were priced from $40 to $80, but shop around. And check to see whether a monitor is covered by insurance.
