If you are tired to constantly change the bulb, use one of the tips below. But in all cases success is achieved through a substantial reduction in voltage. In the daytime and especially at night, the voltage often reaches 230-240 V, which leads to accelerated burnout of the filaments of light bulbs. It is estimated that the excess voltage of only 4% compared to the nominal (i.e., from 220 to 228) shortens the lifespan of the bulbs by 40% and with increased “power” of 6%, this period is reduced by more than half.HOW TO EXTEND THE LIFE OF THE BULB?

“I know, I know— says a reader, after reading the title.— Yes, but neither “alive” nor “dead” water does not happen. Tales!..” Is he right? A few years ago, the magazine “Inventor and rationalizer” announced that we have developed a device that allows you to do “live” and “dead” water. And if you speak the language of chemists, water with a very strong acidic and alkaline reaction. It turned out, ordinary water can be decomposed as two components with opposite properties. According to statements of many who have experienced their actions, “living” water beneficial to the complexion, softens wrinkles, improves hair growth, reduces hair loss, is a good remedy for burns. But “dead” water bad acts on the mouth, reduces gum bleeding.
Many motorists available means, to improve the performance of various components of your machine. Considerable help in providing them electronics. To take at least a variety of electronic ignition system, which “M-K” repeatedly told. Today we offer the owners of “Lada” and “Cossacks” to build a simple electronic voltage regulator (ZRN), constructed in Kharkiv by B. Krutikova.
Psychologists have long determined that the health of a person, his emotional state during labor or active vacation influenced by the color of the surrounding objects, walls, floors. For example, a greenish tone to soothe, and, conversely, red — toned fruit. This means that changing the color of the background environment, interior, can affect the psychological state of the person, his health. But the color of the interior items — the property is fairly constant, static; to change the color scheme of the room, will have to glue the Wallpaper, repaint the furniture, change the upholstery…
No matter what the destination nor was the lamp in its package must include the shade or reflector, limiting the dispersion of the luminous flux and directing it to a functionally important area. Hence the increased demand in electronics stores, unusual chandeliers, sconces, floor lamps. And many are taken to make them yourself.
Yellow, almost sunlight fills lying under a table lamp a book. To read easily and pleasantly; but after an hour and a half, and you notice that colors start to get bored. To rectify the situation is very simple: you turn the handle-regulator, and color light changes gradually. From the solar spectrum, you can choose any — from red to dark blue, and you can change not only the colour but also its saturation.
At home we often have to work with electrical tools and appliances (electric, eletronica, furnace, etc.) at a considerable distance from the outlet. And if the extension wire has a greater length (>25 m), it becomes difficult to unwind, to reel and store.
What motorist don’t care how secure your vehicle against theft or intrusion by unauthorized persons? Here, as a rule, comes to the aid of electronics. However, most electronic devices designed for protection of vehicles, often complex and expensive; moreover, they often need isolated from the body of limit switches. This limits the wide application of such “watchmen” motorists.
This device whose description was published in the journal “Funkamateur” (GDR), used in various measuring devices or equipment, where necessary intermittent light or sound alarm. Moreover, the load can be connected both with the positive and the negative pole of the power source.
