CocktailPi is not only a piece of software. It’s a cocktail-mixing-machine, that works with a Raspberry-Pi, that controls multiple pumps, which have different ingredients assigned. CocktailPi provides a UI, that can be accessed via web browser. Admins can create other users and assign them to multiple roles with different permissions. Users can create own cocktails and if CocktailPi has all the needed ingredients, they can order them. Cocktails can be categorized and shared with other users.

New recipes can be created in the UI. The user can add ingredients to different production steps. Ingredients that are in the same production step get bottled at the same time. The order in which ingredients get bottled can be changed via drag & drop.

Main Features:

The controlling software is designed to enhance your cocktail-making experience like never before. With its advanced features, you can easily create and customize your favorite cocktails with just a few clicks.

• Add and edit recipes within the user interface.
• Extra user interface for enhanced local touchscreen usage.
• Virtual stirring functionality.
• Switch between user interface languages.
• Support for up to 153 dc pumps using GPIO expanders.(No software limit)
• Add written production steps to recipes
• Prompt user to hand add ingredients, that are owned, but no connected to a pump
• Manual activation of pumps (as a cleaning program)
• Ingredient substitution for greater flexibility.
• Put recipes into collections and categories
• Adjustable default filter
• Custom recipe adjustments can be made while ordering.
• Create recipe collections for easy organization.
• Multiple users with different roles can be added for greater security.
• Event system allows for triggering custom actions at specific events.
• Manual production steps can be added and prompted during production for greater precision.
• Automatically detect which recipes can be ordered and which cannot, for smoother operation.
• And much more ….

Call to action

Developing the software for this cocktail machine took a lot of time, and I still have features in mind that I want to implement. The cocktail maker software doesn’t send any data to me or other third parties, so I don’t get any feedback when someone is using the software. If you like the project, please consider giving it a „star“ on GitHub so that I can see that people are using it. Alternatively, I would also appreciate donations. The latter can be done here: https://github.com/sponsors/alex9849

Build the hardware

You can find a more detailed instruction with an example list of building parts on the project website: https://cocktailpi.org/building-instructions/

In order to use this machine in a useful way, you need to build your own hardware. CocktailPi produces recipes by controlling a relay board, that opens or closes the electronic circuit for multiple pumps, which pump the different liquids into the glass. It is also possible to use stepper motors instead or dc motors. The user can add new pumps in the webinterface, where he has to specify a GPIO-Pin for every pump and how long that pumps needs to pump exactly one centiliter in milliseconds. You can build your machine as you like. The only important thing is that you need to be able to apply that concept to your setup.

This is an example setup:

...or with voltage director relays, that allow reverse pumping:

...or with GPIO expander, voltage director, stepper and dc pumps:

This is the hardware that I've used for my machine:
