External Bluetooth Antenna for Increased Range!

I wanted to listen in on some bluetooth at my local Starbucks! but the antenna range on most bluetooth dongles is so short. so i had to increase the range! Here is my epic journey to do so.
This idea of awesome proportions is from thisthis site.

FIRST THINGS FIRST
Music, for this hack i listened to an iTunes Genius playlist based on Evil by Interpol. Including CSS, The Bravery, Modest Mouse, Yo La Tengo, Menomena, MGMT, Franz Ferdinand and Death Cab.
it was beautiful.

In order to do this, I of course needed a bluetooth dongle! (I love saying dongle. dongle dongle dongle!) After shopping, I pulled out the trusty credit card (lifesaver of the unemployed) and purchased this mighty little dongle.

it even has an external antenna! great for hacking into a better one.

upon receiving my package in the mail, and pulling out the usual junk (except the nifty USB extension cable! SWEET! a female USB plug for my next project!) I came to the mighty dongle of justice. the first thing i noticed was the case was already coming apart... so i finished the job and oh my! discovered that it has no external antenna. just a faux one.

so after some googling. found thisthis fancy instructable, on adding an external antenna.

For my antenna, i decided to use what I had. which was an old WRT54G wifi router. with some slick dremeling, and soldering i had my antenna!

now find the antenna on your dongle (haha!) and solder the two wires of the pigtail onto the two antenna pads!
