David Hopkins built his own BarBot for dispensing cocktails (on a budget)
With this cool contraption you can pour cocktails with a touch of a button. It has a single pump with multiple clamped valves that can be configured to pour multiple recipes that are stored on an SD card. It also features a cleaning cycle so that once you are done with serving, you can flush the system leaving it ready for the next use.
