MacGyver: DIY Pen Wi-Fi Antenna

Normally, modifying cheap ballpoint pens is reserved for the prison tattooing systems, but this is a handy mod to boost the signal of a laptop wireless card with some tools. This process is done with the help of 1 foot of rg58 cable, a pen knife, ruler, wirecutters, masking tape and a soldering iron and solder. This is definitely a good project if you are looking to get a little boost out of your antenna without having to shell out an arm and a leg for the officially licensed antenna boosters.
