Device to pour drinks

The first person to press the button starts the filling cycle. If you press once, a whole glass will be poured, if you press twice, half will be poured, if you press three times, a third part will be poured. If you press the button or remove the cup during filling, the filling stops. The machine can count the number of filling cycles. - first filling, second filling, etc. He also gives out 14 toasts, which are recorded on a USB flash drive in mp3.

I wanted the device to be small, not interfere with the plates with food, have simple controls, create the impression of service and entertain a little. Previously, I came across such crafts on the net, but some looked like homemade products, while others looked so cool that they had a place only in a museum.
