Refill Your Drink by Email with Smart Coaster
Last week we told you about Kegbot, a nifty kegerator contraption with a computer built in. Not to be outdone, German scientists have developed an electronic drink coaster that knows when a glass is nearly empty and automatically asks for a refill. Getting a drink refill by email? O brave new world that has such beer coasters in it!
Andreas Butz at the University of Munich and Michael Schmitz from Saarland University came up with the idea while out drinking with their students.
The disc-shaped mat can be attached to a normal beer mat so that it still soaks up spilt liquid and displays an advertisement. But it also contains a pressure sensor and radio transmitter to alert bar staff of the need for a refill.
The device weighs 110 grams and costs $100 to make, but Butz and Schmitz think the weight and cost would shrink if the mat were to be mass-produced.
