Solar Motion Sensor Lights

    Solar Lights have been part of many debates in the last few years. The use of solar lights has become widespread with the availability of solar panels and consumer products. Many such solar lights are now available in the form of motion sensor lights for front doors, gardens, patios, garages and security cameras. The popularity of these solar motion lights (J-A-02-03) in the consumer market may lie in their parts analysis, operating principle and easy installation.


    First of all, solar motion lights have relatively simple parts that make it easy to follow their function. It has an expansion pillar hinge to screw these lights on any exterior part of the residence such as decks, patio, fences etc. They also come equipped with solar panels that are recharged by sunlight every seven to twelve hours for overnight lighting. Then, there is a motion detector underneath the solar panels that acts as a motion sensor and activates for any moving objects within a two-meter distance range. Also included with the other parts are the LED lights with an auto-bright feature for night lighting, lasting ten seconds after activation. The motion sensor light will turn bright as moving objects are within its two-meter range and turn dim as objects move away from its two-meter range to conserve power. Inside the casing is a small PCB (printed circuit board) with a small microprocessor - a look-alike of the LM555 timer chip and a few other parts like resistors. This PCB not only keeps the motion sensor working but also makes it possible for the energy from solar panels to be converted for use in the LED lights. Hence, the function of these simple motion sensor light parts is relatively easy to follow.


    Secondly, the easy installation of this product may make it a popular consumer choice. All one needs is a drill bit to drill holes in concrete. Next, screw plugs are provided for two screws about two cm in length to mount this product on walls and concrete. For decks, fences and garden gates, one may simply use a screwdriver with a square bit to mount this product. Also, provided with the screws is a pin to activate the device on and off. Once the device is activated, it's ready to use. Hence, the easy installation of this product may give these lights good consumer reviews.


    In conclusion, the solar motion sensors may not only provide illumination in the dark but also function with the security cameras to provide crystal clear recording in case of auto thefts and home burglaries. The strength and the timing for the lights may only be evaluated after this product is fully tested by the consumer, which may take a few days, especially in the winter, as the product is said to activate when kept under seven to twelve hours of direct sunlight.

10 Most Expensive Typos Ever

       Whether it’s the programmer making an error in writing the code or an accountant making a blunder in a contract agreement, some Grammar mistakes cost companies millions, if not billions, of dollars. Letters that change the identity of an organization, punctuation marks that change the meaning of a sentence or even spelling typo that makes the reader ignore the main details of an essay ; all contribute to expensive blunders in history. Anyone can write a program code , but the ones that last are the ones that improve lives rather than make them miserable. Whether it's a missing keyboard key, a blurry computer screen or improper wrist orientation, an error is easy to make. After all, "to err is human". Unfortunately, the mistakes that cost millions are not very "forgiving" or "divine".

Driver Safety

        Dash Cam      Since the early 20th century, when the  automobiles were invented there have been millions of road accidents claiming millions of lives and millions of dollars from vehicle collision damage . Many of these accidents require the vehicles to be trashed in the junkyard for parts. Some accidents are lucky enough to have a minimum collision damage to vehicles that may be repaired and placed for resale in car showrooms. However, the prices of these vehicles  depreciate  even before the relisting of the vehicles. The buyer may also end up paying  high insurance premiums and maintenance based on make, model, mileage, and conditions of these vehicles. Manufacturers may be the least to blame for unfortunate circumstances that lead to most major accidents. There is no safety feature or material in the world that will stop metal and glass from penetrating the bare human body. Even Kevlar  vests  are only effectiv...
