We saw a number of Electric Imp demos and appliance ideas at the booth including a simple hand-held "detonator" toggle switch with LED, seven-segment counter, water level sensor, servo-controlled gauge, RGB light, power socket, Christmas light, power monitor, toy washing machine, 16x16 LED display and receipt printer (the latter two being combined to show the avatars and tweets of anyone mentioning the Electric Imp) -- all Internet aware.
The LightSpeaker, which comes complete with a dimmable LED bulb and full-range speaker, fits 5- and 6-inch recessed light fixtures with a standard Edison socket.
