Arduino device helps 'split the G' on a pint of Guinness

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 […]

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. This device solves that problem by vibrating when Magd sips just enough Guinness to result in a split G. It does that with an Arduino UNO Rev3 that monitors the stout in the glass with a non-contact liquid level sensor. Traditional liquid level sensors, like floats, require physical contact with the contents of the vessel, which can be unsanitary.
