It always amazes me how simple, low tech solutions can fix our modern problems. The New York Times has a very interesting article with a few home remedies that may fix some of our most common gadget headaches. Two of my favorites are:
1. To extend the range of your remote car door fob, place the metal part of your key fob against your chin. This allows your head to act as an antenna for the signal thus allowing you to lock/unlock your car from a great distance. (Don't ask me about the medical effects of using your head as an antenna, but I can't imagine it is any worst than holding a cell phone up to your ear.)
2. I always hate when I try to print something from my inkjet printer and the printout has white streaks running across it. This is often because the ink isn't getting through all the print nozzles. In addition to using the printer’s nuzzle clean function, try pulling the ink cartridge out running and a hair dryer on it for two or three minutes the heat softens the ink giving it a better chance of getting through the print nozzles.
