Slot machine? Shot machine? In the case of the BarBot, it's the same difference. As part of a contest, a collective known as NYC resistor spent 300 hours assembling this slot machine drink dispenser.
Each of the three slot wheels has various cocktail ingredients, which tell the drink dispenser what to make after a combination has been locked in place (it's programmed only to form combinations which make actual cocktails). Various liquors and mixers are connected via pressurised tubing powered by a microcontroller and solenoid valves. And to top it all off, it was given a Fear and Loathing in Las Vegas theme. Awesome.
