[Assam] Low-Tech Fixes for High-Tech Problems

[Chan Mahanta]

I am, sure some, if not most, of these tricks do work. Recently there 
was a large list of ordinary household things that can be used for 
solving numerous problems in our local newspaper.

I will caution netters about the following however:

Recently the  hard disk in my Mac G4 -- very early one -- started 
acting funny. This is the machine I do my CAD work--very important! I 
realized that it was about to die. Promptly I got me an used G4 - 
much faster one, from eBay and transferred all my data from the 
ailing old machine. But there was this archive of old e-mails that 
somehow did not get loaded on the newer machine--or so I thought.  By 
now the old hard disk has finally breathed its last -- it would not 
boot up any more.  I called around to see what it might take to get 
the lost e-mail files recovered by a professional. Very expensive! 
So I read up on do-it-yourself hard-disk revival tricks in Google. 
The freezing technique  was widely touted. There were other , even 
more primitive ideas, like dropping the hard disk on a hard floor 
from about a foot above.

I tried the freezing technique. Did not work! I dropped it too. Still 
no luck. Called around professionals across the continent one again. 
Found one in California that charges the least amount--$ 300.  I told 
him about my do-it-yourself attempts. He told me that  it was a VERY 
BAD idea to do so . Apparently early hard-drives might have worked 
with the freezer treatment, not today's more precision designed 
machines. Besides, once you bring the HD out of the freezer it begins 
to condense moisture inside, that REALLY messes it up bad.

So much for the freezer treatment !

But the good news is that, I did NOT lose the e-mail archives. It got 
loaded in a folder that I did not know existed :-)!

The newer G4 is able to run Mac OSX 10.5, which has Time Machine on 
it. Time machine does automatic back-up of everything on to a 
portable hard drive.

>>  *****Cellphone Losing Charge*******
>>
>>  If your cellphone loses its battery charge too quickly while idle in your
>>  pocket, part of the problem may be that your pocket is too warm.
>>
>>  "Cellphone batteries do indeed last a bit longer if kept cool," says Isidor
>>  Buchanan, editor of the Battery University Web site. The 98.6-degree body
>>  heat of a human, transmitted through a cloth pocket to a cellphone inside,
>>  is enough to speed up chemical processes inside the phone's battery. That
>>  makes it run down faster. To keep the phone cooler, carry it in your purse
>>  or on your belt.
>>
>>  This same method can be used to preserve your battery should you find
>>  yourself away from home without your charger. Turn off the phone and put it
>  > in the hotel refrigerator overnight to slow the battery's natural tendency
>>  to lose its charge.
>>
>>  *****Remote Car Key*******
>>
>>  Suppose your remote car door opener does not have the range to reach your
>>  car across the parking lot. Hold the metal key part of your key fob against
>>  your chin, then push the unlock button. The trick turns your head into an
>>  antenna, says Tim Pozar, a Silicon Valley radio engineer.
>>
>>  Mr. Pozar explains, "You are capacitively coupling the fob to your head.
>>  With all the fluids in your head it ends up being a nice conductor. Not a
>>  great one, but it works." Using your head can extend the key's wireless
>>  range by a few car lengths.
>>
>>  *****Dry Ink Cartridge*******
>>
>>  If your printer's ink cartridge runs dry near the end of an important print
>>  job, remove the cartridge and run a hair dryer on it for two to three
>>  minutes. Then place the cartridge back into the printer and try again while
>>  it is still warm.
>>
>>  "The heat from the hair dryer heats the thick ink, and helps it to flow
>>  through the tiny nozzles in the cartridge," says Alex Cox, a software
>>  engineer in Seattle. "When the cartridge is almost dead, those nozzles are
>>  often nearly clogged with dried ink, so helping the ink to flow will let
>>  more ink out of the nozzles." The hair dryer trick can squeeze a few more
>>  pages out of a cartridge after the printer declares it is empty.
>>
>>  *****Cellphone in the Toilet*******
>>
>>  It could happen to anyone: you dropped your cellphone in the toilet. Take
>>  the battery out immediately, to prevent electrical short circuits from
>>  frying your phone's fragile internals. Then, wipe the phone gently with a
>>  towel, and shove it into a jar full of uncooked rice.
>>
>>  It works for the same reason you may keep few grains of rice in your salt
>>  shaker to keep the salt dry. Rice has a high chemical affinity for water -
>>  that means the molecules in the rice have a nearly magnetic attraction for
>>  water molecules, which will be soaked up into the rice rather than beading
>>  up inside the phone.
>>
>>  It is a low-tech version of the "Do Not Eat" desiccant packets that may
>>  have been packed in the box the phone came in, to keep moisture away from
>>  the circuitry during shipping and storage.
>>
>>  *****Longer Wi-Fi Reach*******
>>
>>  If your home Wi-Fi router doesn't reach the other end of the house, don't
>>  rush out to buy more wireless gear to stretch your network. Instead, build a
>>  six-inch-high passive radio wave reflector from kitchen items, like an
>>  aluminum cookie sheet.
>  >
>>  Follow the instructions at 
>>*freeantennas.com/projects/template*<http://freeantennas.com/projects/template>.
>>  Place the completed reflector - a small, curved piece of metal that reflects
>>  radio waves just like a satellite TV dish - behind your Wi-Fi router. It
>>  focuses the router's energy in one direction - toward the other end of the
>>  house - rather than letting it dissipate its strength in a full circle. No
>>  cables, no batteries, no technical knowledge required. Yet it can easily
>>  double the range of your network.
>>
>>  *****Dirty Discs*******
>>
>>  You need to clean a skipping DVD or CD, but as a bachelor you don't have
>>  any sissy cleaning fluids? Soak a washcloth with vodka or mouthwash.
>>
>>  Alcohol is a powerful solvent, perfectly capable of dissolving fingerprints
>>  and grime on the surface of a disc. A $5 bottle of Listerine in your
>>  medicine cabinet may do the job as effectively as a $75 bottle of DVD
>>  cleaning fluid. Also, swabbing your copy of "Lost Weekend" with Stoli
>>  instead of fussing with a Discwasher kit is a lot more manly.
>>
>>  Too Much Flash
>>
>>  If your cellphone's built-in camera flash is much too bright, washing out
>>  photos, tape a small piece of paper over the flash. Experiment with
>>  different colors and thicknesses of paper to tone down the flash from
>>  superbright white to a more pleasing glow for evening photos.

>>  That may help free up binding parts, Mr. Langa explains, or at least let a
>>  failing electrical component remain within specs long enough for you to
>>  recover your essential data.
>>
>>  That's the spirit of folk remedies: They may or may not work, but what have
>>  you got to lose?
