Behind the cash register of the tobacco 2 in the center of San Francisco, Sam Azar is the credit card of a customer buying cigarettes Turks. The card machine shop can not read the magnetic strip. Chance of happening again, and again, without success. When a queue begins to form, he takes a plastic bag under the counter. Wrap the cardboard with the plastic and goes again. Success. The sale is held.
"I do not know how, just know it works," said Azar, who learned the trick years ago with another attendant. The Verifone, a company that manufactures the machines readers, does not confirm or deny that the bag works. But this is one of many low-technology solutions for technology failures, people without engineering degrees discover, often to despair, and share.
The current unstable economy makes the creation of these tricks is much more likely. "In Japan after the war, the economy did not go very well, and you could not items of daily use as cloths for cleaning," says Lisa Katayama, author of "Urawaza," a book with the name borrowed from a Japanese term that tips and tricks to designate a method of intelligent life. "So people sought ways to turn to what they had."
The collection includes popular urawaza shards of glass from the floor using a slice of bread, or put plants in a diaper soaked with water to keep them hydrated during a vacation trip.
Some tricks, such as plastic bag Azar, are open to discussions on its operation, or if they really work. But many home technology solutions can be explained by a bit of science.
Load cell
If your cell phone battery discharges too fast while in your pocket without use, the problem may be that your pocket is too hot.
"Cell phone batteries actually last longer if kept cold," said Isidor Buchanan, editor of the Battery University site. The heat of 37 degrees Celsius of the human body, passed through a pocket of tissue to a cell within it, is sufficient to accelerate the chemical processes within the phone's battery. This means that it is used up more quickly. To keep your phone cooler, load it into your pocket or belt.
This same method can be used to preserve your battery if you look far from home without the charger. Unplug the phone and leave it in the refrigerator overnight to slow down the natural tendency of the battery to lose its load.
Car alarm
Suppose that the alarm for the opening of your car does not have the power to reach the vehicle across the parking lot. Pull the piece of metal in the key of your chin and press the button to unlock. The trick turns his head in a dish, said Tim Pozar, a radio engineer in Silicon Valley.
Pozar says: "you are the key to uniting his head. With all the fluids in your head, it ends up being a good driver. Not the best, but it works. "
Dry Ink Cartridge
If the cartridge from the printer finished near the end of a major print, remove the cartridge and run a hair dryer on it for two or three minutes. Then place the cartridge back and try to print again, while it is still warm.
"The heat of the dryer heats the paint hard and makes it flow through small nozzles in the cartridge," says Alex Cox, the software engineer from Seattle. "When the cartridge is nearly finished, those nozzles often are virtually clogged with dry ink, then help the ink flow will make it happen." The trick of the hair dryer can get a few pages to more than one cartridge, which then the printer reported that it is empty.
