Wardriving with a Raspberry Pi

This is neat, they gent in the article built a wardriving (tool to drive around with and find open wifi networks) with a Raspberry Pi, directions are pretty good.  I think you could get a few of the parts cheaper, but a certain author may remember building similar things way back when with a full laptop…
