Robert Prest has used a grandfather clock to house his latest project: a Bar Clock. The automated system can pour drinks with up to four spirits and four mixers and is controllable using voice, web GUI or keyboard. The platform onto which you place your glass is belt-driven and comes out via a spring-loaded door. Peristaltic pumps control the flow of the spirits while taps are opened via servos for the mixers. There’s a Raspberry Pi doing all the robotic control with an Arduino to switch on the lighting. You can see a quick run-through of a cocktail being made in the first video below, whilst a more in-depth walk-through is available via the second video.
