Make your own external cell phone antenna.

If you aren't interested to spend a couple of hundred dollars for an external cell phone antenna then this is a must for you. Robert had made an ultra-cheap external cell phone antenna from coax cable and a h?nger which had worked for him.

Make your own external cell phone antenna (11) 1You'll need the following materials:

* A wire pants h?nger
* A length of coax cable (2' should do)
* A plug that fits into your phone's external antenna jack on your phone.

You'll need the following tools:

* A cutting tool for cutting the h?nger wire
* A drill for the cardboard portion of the h?nger
* A ruler with 1/16" increments
* A soldering iron and solder
* A pen / pencil


Construction
# Disassemble the h?nger.
The wire will be used for the antenna elements and the cardboard tube will be used mount the elements.

# Cut the following lengths of wire (except the DE at this time) and label them:

* R = 3 1/8"
* DE = 2 7/8" (remember, don't cut this one yet)
* D1= 2 13/16"
* D2 = 2 3/4"
* D3 = 2 3/4"
* D4 = 2 11/16"
* D5 = 2 5/8"
* D6 = 2 5/8"
* D7 = 2 9/16"

The piece DE (aka Driven Element for you Antenna designers out there) is going to be"J" shaped. The length of the top half will be 2 7/8" and the bottom half will be 1 7/16" and the distance between the top and bottom will be 1/2".

Along each side of the cardboard tube, draw two lines running the length of the cardboard tube. Make them roughly opposite ends of the tube from each other. The spacing isn't critical, this will just help make the elements come out in a parallel plane.

Mark the following spots from one end of the cardboard tube on each of the lines drawn previously.

* R = 1/2 "
* DE = 1 11/16"
* D1 = 2 7/16"
* D2 = 3 3/8"
* D3 = 5"
* D4 = 6 11/16"
* D5 = 9 3/16"
* D6 = 11 11/16"
* D7 = 14 5/16"

# Drill holes in the cardboard tube.
At each of the marks on both sides of the cardboard tube. The tube is hollow, so be careful to go through only one side at a time.

# Insert the elements into their respective holes.

# Prepare the coax cable.
There are usually five layers to coax cables. The outer plastic cover, a braided set of wires. Under the braided wires is a tin-foil thick covering of metal. This covers a thick plastic section with a thick copper wire in the center. If you are using a spare cable with coax connectors on both ends, cut one end off.

Carefully cut away the outer plastic cover about 3/4" from the end of the coax of an end of the coax cable with no connector.

Make your own external cell phone antenna (11) 6# Attach the coax cable to the cardboard tube. Put the end you just prepared near the DE element and tape it in place. This will help with soldering.

# Solder the coax to the driven element. Just put one at the center of the top and the other just below it.

# Attach the coax cable to the phone
If you didn't buy a plug, you will want to fabricate a plug of some sort. If you're lucky, you have a phone where it's obvious where the leads go, but some have a plug with multiple leads and you would have to do some research to find which ones to use.

Tuning
This is a directional antenna, so you'll have to figure out which direction works best. If you're not sure, pick a random direction and wait 10-15 seconds to see if a better signal is registered. Generally a phone may take about 30-45 seconds to get to 4 bars. If you don't see any results, turn 45 degrees and wait again. Odds are, you should be able to figure out the optimal direction in just a couple minutes.

Computer or Spouse: whom would you choose?

A very interesting question, had you had a choice of choosing whom would you choose?
A new study reveals this:

65 percent of Americans spend more time with their computer than their spouse - and, on average, wastes 12 hours a month fixing computer problems. "As computers become increasingly pervasive in our lives, our relationships with them can begin to seem almost as important as a relationship with a significant other. When problems then occur with the computer, it often leaves people feeling helpless," says Dr. Robi Ludwig, host of the reality series One Week to Save a Marriage on cable channel TLC.

Is it possible to locate a man given only his photograph and first name?

Quite amazing it is:

A UK-based game company is testing the theory of six degrees of separation. They have given us a photograph of a man, a name, and the Japanese characters that translate to "Find me". We are each only five to seven people away from any target in the world. Someone, somewhere, knows Satoshi. Help spread the word and track down this person!

The long form of the name is the longest officially recognized place name in the United Kingdom and one of the longest in the world, being 58 letters in length.

Officially the longest word is 'floccinaucinihilipilification' at 29 characters, meaning 'the act of estimating as worthless'. Act of estimating as worthless? The number of letters in it already had spoken for self & hence further need not be termed.

Humans on display in a Zoo.


An Australian zoo has put humans on display to raise awareness about primate conservation. Audience have the option of voting for their Favorite ape via test messages.

Total 24 humans will be on display in the said Human Zoo during the month of January & each exhibit has a group of six humans on display, under the care of scientist Dr Carla Litchfield. The people on display will be changed from one exhibit to another.

Group 1 exhibit will be from 8 to 14 January 2007 having three men & three women.

Group 2 exhibit will be from 8 to 14 January 2007 again three men & three women.

Group 3 exhibit will be from 15 to 21 January 2007 same again three men & three women.

Group 4 exhibit will be from 22 to 26 January 2007 same combination of men & women.

This project aims to
* Create awareness of the closeness of humans to their primate cousins
* Provides a platform for research on animal behaviour and enrichment
* Raise awareness for the conservation needs of primates in the wild
* Raise funds to build Australia's largest chimpanzee exhibit at Monarto Zoological Park in South Australia

Its said that "Live streaming by Adam Internet will be available on the internet on the Adelaide Now website".

Earlier also one such exercise did happen in London in the month of August, 2005 at London zoo where the exhibit featured three men & five women clad in bathing suits.
