Counter pressure bottle filler

Semi automatic counter pressure bottle filler

heavily inspred by: https://hobbybrauer.de/forum/viewtopic.php?f=21&t=18859&hilit=gda

Main goal was to design a semi automatic counterpressure filler which can be easily built without any machining.

There is no contact between the beer and the 3d printed parts ==> only food grade materials are in contact.

The filler is controlled with an arduino nano, the fill level is sensed with the help of an xkc-y26-npn sensor ==> only works reliable with 24V!
