I just finished watching the third installment (Box 3.0) of From The Shadows, an internet "TV" show about underground technology hacking. It's made by my pals at Flexilis and some of the visionaries from, now defunct, TechTV. This is worth watching!
This episode is jammed with hardcore Wi-Fi exploration. The guys go warviewing (and warviewflying?) using high power antennas and end up finding unencrypted wireless cameras in a bank building. Yoshi mods a Sony PSP with a pigtail connector and attaches a panel antenna to increase the gaming distance to over 600 feet. And Humphrey Cheung shows step-by-step WEP cracking and explains what it's all about.
They mentioned that the book Wi-Fi Toys might be a good place to start your 2.4 GHz project. (I tend to agree.) - Thanks guys!
