If you could stay sober long enough to build one , a company called Sentilla has developed a DIY “ smart ” beer coaster that could lead to a myriad of new drinking games for you and your friends to bask . The coaster is “ bright ” in the mother wit that it can find when a potable is present and when it is absent , it can communicate with nearby coaster , and it can allow feedback in the phase of flashing lights . Plus , it does it all wirelessly . More info and a video recording of the coaster in action are available after the falling out .
Besides its more obvious and pointless applications , Sentilla also suggest that these smart coaster can be used to notify a barman when you are in need of a raw drink . in person , I would rather predate the seizure and utilize a moreelegant solvent . Still , if you would like to stress your hand at building one , instructions are available on the Sentilla site . [ SentillaviaInventorSpotviaGeekologie ]
