Will this get me a better wifi signal?

I've been looking through a lot of the wifi ibles. My computer in on the other side of the building from the router and I'm trying get a stronger signal. Before I permanently damage my wireless card antenna, would using alligator clips to connect my antenna to a roll of wire or something work?

http://www.instructables.com/id/10--WIFI-16dBi-Super-Antenna-Pictorial/ makes a great high-gain directional antenna...

the poor man's directional attachment works too.

No. The trick of using a wire (essentially a dipole antenna) works for relatively low frequency signals, like AM radio. What you want is simply a reflector/concentrator. I have a colleague who cut a big coffee can in half and uses that as a poor man's "parabolic" (cylindrical, but the spherical abberation is irrelevant here) reflector. Put it to the side of your WiFi card, with the card's antenna at the focus, and the open part pointed roughly in the direction of the WAP.
