I haven't done anything with gumstix and I've been trying to find a means to an end, I've been wanting to make a custom wi-fi detector out of a gumstix for a long time now, The problem is, it seems like there is no gumstix that supports wi-fi and an LCD screen making it incredibly annoying to use for that, Also I'm not even aware if batteries are supported.
 
Basically I'm trying to make a high tech wi-fi sensor that will actually show the signal strength, Broadcast ID, and ETC as if I was walking around with a laptop and the program inssider constantly. Basically a gumstix that supports Wi-fi, Battery, and LCD. Is there any such thing?
