What happens when the O'Reilly folk drink too much coffee? They take a lamp, a powerline ethernet bridge wireless access point and combine them. The result is wifi access in a lamp, and thanks to the powerline networking, no CAT 5 cabling to the lamp.
One trip to the hardware store later, we had a variety of Edison plugs, sockets, and adapters. We settled on a simple extender type of device, with a female socket on one side and a male plug on the other. Again, the contacts were copper, making it easy to solder on more romex. We had the basic design together, but what could we possibly use as a housing?

Tupperware, of course. Adam painted the inside of a tupperware bowl white, and the entire device just managed to squeeze inside. We first attempted to take the SpeedStream unit apart to save space, but it's already tightly packed inside (much of the unit is occupied by a large transformer.) Besides, keeping the original enclosure made us all feel a bit more relaxed about plugging the thing in. The Edison plug poked through the bottom of the bowl, where we simply screwed on another one to keep it tightly attached.
