Drink Maker

Automatically mix drinks from up to 6 bottles, all controlled from your phone. It's a fully functional drink dispenser controlled by a Raspberry Pi Zero W. Needs a Raspberry Pi Zero W, a 9v battery, silicon tubing, 6 solenoid valves, 6 small one-way check valves, 6 transistors, 6 bottle pouring spouts, wires and glue (superglue + food grade silicon glue for the tubes), all of which can easily be found on Amazon. The whole build out cost me around $100 of materials. The hardest part is making sure everything is glued in well enough so it doesn't leak. I just run a Flask server on the Pi itself so anyone on my Wi-Fi network can have it mix drinks from their browser.
