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.
Since there's no physical interface on the device to configure WiFi, the company's developed Blinkup, a way to enter SSID and password information on any iOS and Android smartphone and beam it to the Electric Imp's light sensor by rapidly pulsing the handset's screen on and off.
If you remember, the Electric Imp is part of this whole Internet of Things trend and has the potential to transform common appliances into interconnected devices.
