The Barnet Box! An interface box developed by the London Borough of Barnet and Commotion.
The Barnet Box is very simular to a Smart Box.

The box itself has 8 inputs, 8 outputs and 4 motor outputs. The power level of each output can be adjusted from 1 to 9. (The power level is done using pulsing)
The box also has an external power output of 6 or 12 volts, this is selectable via a key.
