I thought this was nifty. Make your own wireless extender for five cents.

That + Linksys Router + DDWRT (or similar) = amazing

From memory, this hack only works with 2.4 GHz antennae. I don't think it works with N band 5 GHz, but i'm not sure

Was in inches so I cant do it

I remember when small pocket transister radios come out in the 1960s. We used to wrap copper wire around them to get a better reception.

2" = 5cm so 1" = 1.5cm

Put your thumb to your forefinger and bend it to 2 right angles putting the two nails together, the distance from the 2nd joint to the third is about an inch, 12 of them is about the size of your foot, 5280 feet is one mile, 25,000 miles circumference of Earth, 6000 miles diameter of Earth, 250,000 miles to the Moon, 93,000,000 miles to the Sun.

If the Sun is reduced to the size of a grapefruit, then Earth is the size of a grain of salt 15 meters away, Pluto is a speck 600 meters away and the next star is in Australia somewhere 6000 miles away, on this scale, the diameter of the Milky Way galaxy is 250,000 miles.

This is from memory so may be slightly wrong.

The force of One Newton is the weight of a medium sized apple in the palm of your hand.

If you spit on an electronic equipment heatsink and the spittle immediately boils and evaporates then it is running too hot.

Very innovative.

But not twice the distance. At best this will give a gain of about 5.5 - 6 dBi. A basic Wifi antenna is about 2.8 dBi. So it will give you a gain near 3dB. Thats twice the power in a horizontal direction (at the cost of power in the vertical direction but thats usually no biggie unless you have a 2 story dwelling).

So twice the power will give only 40% additional distance (less through walls).

If the measurements are not the same as the designed antenna then there will be a mismatch reducing the output power and possibly stuffing your transmitter stage of your wifi router. The quarter wavelenght of the original little antenna is about 29mm so getting the length wrong by a few mm or the inductor (the coil bit) wrong (diameter of coil, distance between coils, or number of coils) can have a detrimental effect on the router. So do be careful with the measurements.

Can't be 5c, we don't have those coins any longer. Round up or round down ;)

Stink converter didn't have chains or firkins

As I said. It does most things.
