58% of Americans survey online before shoppping online

Pew Internet and American Life Project has just released the latest the survey results of online shopping habits of Americans . One of it: 58% of Americans said that they have investigated before buying anything online, and this proportion is only 49% in 2004. In these respondents, who call themselves Internet users rose to 78%.

In addition, to investigate not only the proportion of shopping before the increase, and the network of people has also increased the frequency of the investigation.

21% of adults engage in every day of this survey, one in 2004 compared to only 9%.


American research, reviews, online shopping more and more
In addition to the website to read the description of products and services in addition, many people also add a Review of information, analysis, views of the product, especially through social networking sites. 24% of Americans said they would comment after buying things.
The Pew study also online shopping of American spending habits have been studied. There have been online shopping experience of Americans in May 2000 from 36% to 52% now. Meanwhile, online booking air tickets and hotels from 22% to 52%.

The study also found that study habits between men and women of similar, but high-income groups than low-income populations of the network to investigate more. High income and highly educated people post reviews and comments more frequently.

Many Americans are shopping online before comparing the price, quality and product review. Even if the end did not buy the site, but in the store shopping, they will advance the investigation and decision-making on the Internet.

LED Light to Make Fruits and Vegetables More Appetite

Determining whether the light is not correct or simply to deepen the color of the food is subjective, although some LED manufacturers said they remain concerned about the U.S. Food and Drug Administration requirements.

The next time you go shopping or buy the vegetables, look past your fruits and vegetables, you may be surprised by their bright appearance when they are raised. Grocers have now discovered a the secret jewelry store and the cast have known many years - lighting influence.

New LED technology has a dual purpose of invading the retail stores: Save energy and the temptation to customers. When the U.S. government is out of incandescent lamps, the place is the game between the LED and compact fluorescent.

Ireland is a company to enter the U.S. retail market Nualight the Ministry of Commerce senior vice president Paul Kelly "We are the orange as a jewelry, we want to create a wonderful space, this light so that customers feel like eating, taste the food."

Nualigt new base in California and other simple production line to produce the light in New England. Other companies are editing and southeast Texas stores to install LED bulbs. Kelly said he could use digital LED light comparable to the fact that the sun light color. Kelly said his company alone can set the highlight color of the food program - red meat, vegetables or fruits yellow or green. It is very important, because the LED brightness than fluorescent small.

In the Chestnut Hill Star Market, in October 2009 are replaced with LED lights and witnessed both energy and maintenance costs decline, the store owner Liam Flanagan said. Have changed in appearance.

"It does make the food more than the fluorescent hot" Flanagan said. "Fruit than a few customers that do not house more vivid colors."

Green Planet: How much food you can buy by $ 1?

Several states have adopted the U.S. Food and Drug Administration published regulations, limiting the light of some confusion, according to FDA spokeswoman in Washington. Declaration of Conformity "additional food or color material, color packaging, or lights may not be used to cover the true appearance, color or food quality."

"I do not think this will hinder the LED Light Bulbs" Terry Roberts, Design Dallas, director of marketing, said retail consultant. The key question is how to cover, it is not too far. The good news for the LED is practical and you can correct it.

When the LED long life is enough long saving energy, no toxic mercury and less heat than other bulbs produce, it is also more expensive. advocates has many technology say that they will reduce the price when they are widely used. Roberts said that the LED is not too long before the occupation of the domestic market.

"They will make customers feel more delicious because the light would be more appropriate" Roberts said, "It is really big improvement.

Headphone Jack Dock Plug Dust

If you usually do not plug your iPhone headphones, how to prevent the headphone jack into the dust it? It is not just a matter of fact, many cell phone's headphone jack is too large to easily access to the foreign body, after a long time, it is not easy to clean up the a lot of dust accumulation! A Japanese company called hashy-topin launched the product was called Plugy, specifically for blocking the iPhone headphone port.

Its plugs was set into the style of the headphone plug, you can fill the headphone jack, the outside is a lovely decorative shapes, there is a total of 6 shapes include buds, screws, springs, taps, mushrooms and the key. They are made of PVC plastic, so they are strong and environmentally friendly. Not just only for iPhone, all 3.5mm headphone interfaces can use them to block.

Circuit Schematic For DIY LED Light Bulb

Using energy-saving LED lights is the best way for saving energy, it not only save energy, but also it has a long life, etc., so it is popularity! Here I have to introduce energy-saving LED lamp production process, I hope you can make to pay less electricity because of energy saving point.

Figure 1 is a practical LED light Cup circuit, the lamp uses 220V power supply, 220V AC by the C1 capacitor step-down buck by full-bridge rectifier and then filtered through C2 by the current limiting resistor R3 to the series of 38 LED provide constant current power supply. LED is rated at 20mA, but we make energy-saving lamps in the time to consider many factors impact on the LED, including the issue of bad light and heat, installation density is relatively high when we are doing this LED light Bulbs, not easy to shed heat, LED temperature decline and life to light a great impact, if the heat can easily lead to bad light bad, because the LED's characteristics is the current temperature will increase, it is generally in do high-power lighting problems when heat is the most important, will affect the stability of the LED, low-power mode is generally taken from the heat, so the current in the circuit design should not be too large.

Schematic is to protect the resistors R1, R2 is the resistance of capacitor C1 of the unloading place, R3 is a current limiting resistor to prevent the voltage increases and temperature increases the LED current increases, C2 is the filter capacitor, the actual circuit in the LED can not filter circuit , C2 is used to prevent inrush current when the lights damage the LED, lights the moment because of the presence of C1 will be a big charge current, which flows through the LED will produce damage to the LED, with the C2. intervention, turn on the lights of the charging current is completely absorbed played lights C2 anti-shock protection.

If you are worried about your home without a corresponding holder to this light, you could go to, there are many lamp socket converters for you to choose.

The circuit is the most practical low-power lights Cup circuit, taking up small space can be easily installed in less light cup, LED cup products are now widely used. 

Advantages: constant current source, power consumption, small size, economical and practical, but it must need the more 400V polyester capacitor or CBB capacitor, the filter capacitor need more 250v voltage. This circuit is suitable for driving 20-40 only 20mA of LED.

To Rethink The Shape of The Battery

Now we use the batteries are circular, here the designers propose a new concept to design six-sided shape for battery, place the whole up and that is cellular, and compared to the gap of the round, it's unique modeling can save a lot of packaging and shelf space, and because it is angular, it is not as round as we do not know where to roll when placing it on the desktop.
