What can i say? Well who doesn't need this machine.

It has 10 channels, eight smaller ones (~60ml/min) and two bigger ones (~450ml/min). With this configuration a normal cocktail of 250 ml will be ready in under a minute and all you had to do is pressing a button instead of mixing it by yourself. Also the machine is pretty compact. Its size is 140mm*180mm*330mm (w/d/h) and if you don't want to refill or change the connected bottles during an evening, you can use tanks or bins for your ingredients.

The system is controlled by an Arduino MEGA which is programmed based on the LCDMenuLib2 by Nils Feldkämper (aka Jomelo). To have easier connections to the RAMPS display unit i also used the RAMPS shield.

To handle the current of the pumps (~250mA for each small pump and 1.2A for the big ones) i use simple relay boards that get powerd by a volatge step down regulator.

The case is planned for a steelframe (15*15*2). The panels are all 3D printed (20*20 printer is enough) and extremly modular.

    Frame building

    Cut metal:

    • 4 times 330mm*15mm*15mm
    • 4 times 150mm*15mm*15mm
    • 3 times 110mm*15mm*15mm (Free space at the display unit)

    Weld the frame as seen in the CAD files (330mm*140mm*180mm).

    Alternative: Use wood as i used it in my prototype.
