Steve Rundell and fellow engineering students at Michigan State University never go thirsty, thanks to the ingenious automatic drink-making machine they designed and built. The contraption allows the "bartender" to select various drink mixtures displayed on an LCD screen. A controller sends a signal to a servo motor that drives a rotating carousel, which positions the drink cup under the appropriate liquid reservoirs. A solenoid valve opens, automatically dispensing a predetermined amount of liquid into the cup.
