Named after the Sumerian god of happiness and merriment, Siduri is a smart coaster for your drinks. It recognizes when a glass is near empty and then glows yellow to alert waiters that you will need a refill soon.

Designed specifically for lounge and club settings, Siduri helps nightlife revelers politely draw the attention of barmaids and helps bartenders to keep the drinks flowing.

The coaster is powered by Ardunio and uses an FSR sensor that recognizes the difference in the weight of a drinking glass.
