The Tea Engine
My entry for BarBot 2013, the Tea Engine is a robotically controlled tea service made from an antique coffee percolator set from the mid-1920s. Those wishing tea simply need to dial the number on the rotary dial that corresponds to how they take their tea (2 for tea, 4 for tea with milk, 6 for tea with sugar, and 8 for tea with milk and sugar). An Arduino microcontroller reads the number of pulses from the dial and opens for a set number of seconds to dispense the proper amount of tea, milk, and sugar.
The Tea Engine has been featured on Tested.com - photos - video - and in the Oakland Tribune.
