An overview of the hardware you can use to build your own CocktailBerry cocktail maker. Mix and match the parts that fit your build.
CocktailBerry runs on affordable, off-the-shelf parts. Here is an overview of the hardware you can use to build your own automated cocktail maker. You mix and match — there is no single required setup.
This page is a quick starting overview. For the complete, up-to-date parts list with every option and wiring details, see the full hardware list in the documentation.
The essential building blocks. Pick the parts that fit your build and budget.
The brain of your machine. A Raspberry Pi 3B+, 4, or 5 runs the CocktailBerry software. Any of them works — newer models are simply faster.
Your guests order drinks on a touch display. A 5" or 7" screen is the common choice; the official Raspberry Pi touchscreen works too.
A 16–32 GB micro SD card holds the Raspberry Pi operating system and CocktailBerry.
Switches your pumps on and off via the Raspberry Pi's GPIO pins. Use a relay board for simple on/off control, or a motor shield for finer control.
You need two separate circuits: one 5V supply for the Pi and a stronger supply for the pumps — the Pi alone cannot power them.
Food-safe hose carries your ingredients from the bottles to the glass. Plan for roughly 5–10 m depending on your number of pumps.
Female-to-female jumper wires connect the relay board to the Pi, plus the usual HDMI and USB cables.
Add a USB RFID reader and NFC tags to let guests pay for their drinks — handy for bars, events, or charity setups.
Pumps are the heart of the machine. CocktailBerry drives any standard DC- or stepper-based pump or motor, so the types below are just common examples — not the only options. Each pump is wired through the controller board and controlled by the software.
Self-priming diaphragm pumps that move liquid quickly and handle being mounted above the bottles well. A popular, affordable choice.
Only the silicone tube touches your ingredients, which keeps things clean and easy to maintain. Gentle and precise, ideal for accurate pours.
Whichever type you choose, make sure the pumps are food-safe and powered from a separate circuit — not from the Raspberry Pi.
