A few guys decided to create a Wireless Access Point (WAP) in their favourite coffee shop by modding a lamp. They added a WAP in a lamp cover. The internet connection goes via a Powerline Ethernet and everything is powered by a lightbulb socket! Pretty engineous!
A Siemens SpeedStream 2521 Powerline 802.11b Wireless Access Point would provide the net connection, sourced from the electrical socket. The boys piggybacked the power for a low-energy fluorescent bulb to the WAP , and soldered a standard screw-type Edison lightbulb socket to the unit (middle). The entire setup fits neatly into a Tupperware container to complete the illusion.
