Yes, the DS Fanboys of the world continue to innovate. Hot on the heels of transforming the DS into a wireless PC game controller, the community is using the chameleon-like DS as a Wifi scanner (and using the exact same application they did for turning it into a PC gamepad).

TheYak comes through again with the details via the 3DGPU community forums: "I've idly used my Nintendo DS to look for hotspots with its limited WFC applications, but have wanted a more dedicated scanning application for awhile. Enter DS2Key - It's actually more of a wireless gamepad emulator so you can remotely control games and applications on your PC with your DS. Having some glitches in getting it set up, I checked out its 'Wardriving' section... it quite adeptly displayed signal strengths, WEP status, MAC addresses and SSID's for 6 networks around me. My wi-fi adapters only ever came up with 3. Usefulness? Checking signal strengths (it auto-refreshes) for your networks, looking for DS hotspots for on-line play. Homebrew stuff just keeps getting cooler."

We couldn't agree more.
