Relay shield available today
S_Relay Shield provides an easy ways for smart appliance control. It covers control to normal load circuits with 4 photo-coupled solid state relay capable of switching DC90W (or AC360VA). It also provides stand alone power supply, Bee type wireless module socket, and Native Arduino compatibility. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.

For AC, 360VA is pretty low, it means we can only control 3A devices here in the USA (120 VAC). Any chance of getting a really kickass relay that can switch 15 amps — then we can switch all sorts of neat things! 🙂
Of course, that also increases the likelihood of: 1) us burning the house down; or, 2) electrocuting ourselves and then burning the house down.
