Ever feel the need to have your very own alcohol vending machine at home? Well if you do, [Ben] and [Dan] have just the Arduino based machine for you!
It was actually part of a school assignment for product design at Brunel University – the whole thing was designed and built in just over a week. The machine accepts and counts coins giving you a total readout on the LCD screen. When the correct amount is inserted you can select your shot and the machine will pour you a stiff one.
The thing we like about this vending machine — we’re not sure if it actually qualifies as a barbot — is that it doesn’t have any fancy pumps. In fact, it just uses two inexpensive solenoid valves and gravity to dispense the drink, much like a typical bar bottle dispenser.
