Step 5: Thats all Folks!!

Lets dress her back up again

You could go ahead and leave the project the way it is right now and it should work just fine but lets be honest its not the best looking thing to be stuck out of your computer. So we will put it all back together.

We need to modify the plastic shell so that the pigtail can hangout and still allow the shell to close, again the good old X-Acto knife steps in and saves the day, just pick a good spot you want it to hang from and little by little whittle a small groove just big enough for the cable to sit in.

As a side note when I dismantled the gizmo I noticed there was a cool SMT blue LED on the board that lights up real pretty when the device is in use. You cant see this when the case is on so I also drilled a hole in the case to let the mystical blue light out.

Once you have a nice groove for the pigtail you are done, snap the plastic shell back together and enjoy true Bluetooth freedom.

Well almost, I am using a 6dBI directional antenna and it works well, before the mod I could walk about 5 feet from my computer before I started to get static, now I get a good 20 to 30 feet.

Good luck and happy modding
I have a huawei E-1556 3g modem I'd like to do the same thing you did. Where can I find a picture of the board to figure out where to solder the antenna wires.
I have no idea my instinct would be to crack it open and have a look
I cracked it open but have no idea what to look for as far as where the antenna is and where to solder the wires
Usually in bluetooth dongles, such as above, there is a square wave looking trace (or a tracing going back and fourth in a square looking pattern) on the board, that is usually the antenna part.
Awesome instructable. I have the same one and this extended its range a lot.
Glad i could help
You can use a scanner to take closeup pictures if you don't have a camera with macro.
I no longer have a scanner because I am modding it to become a UV light box for making PCB, stay tuned for that one :)
i a m curious. does your bluetooth adapter come with widcomm or bluesoleil software?
To be honest I am not sure, I am using the windows driver in Vista. Its a broadcom chipset so I would take a guess at Widcomm
