Amateur Logic, Cantenna, Cool-Amp

Tonight I was watching episode 3 (an old episode) of Amateur Logic TV.
The major project of the episode is what they call an "active cantenna"
for Wi-Fi. A clever part of the design is to use a Wi-Fi card/transmitter
mounted in an Altoids tin right on the antenna.

The driven element is a copper nail. To protect the copper
from corrosion they use the nifty silver plating powder from Cool-Amp.
