Arduino device helps 'split the G' on a pint of Guinness (arduino.cc)
Guinness is one of those beers (specifically, a stout) that people take seriously and the Guinness brand has taken full advantage of that in their marketing. They even sell a glass designed specifically for enjoying their flagship creation, which has led to a trend that the company surely appreciates: “splitting the G.” But that’s difficult for many to pull off, so Eamon Magd built this device that makes the trick easy to master.
