We like boba, and are too lazy to make the 10 minute drive to the nearest boba shop. So we made a machine to make boba for us.
What it does
A cup starts at the beginning of a conveyor belt, and goes through a gauntlet - first boba mix drops in the cup, then a coffee pot is turned on and adds hot water, then tapioca bubbles are added, and finally a stirrer is released for you to combine your drink.
How we built it
We used a Python script that pairs with our machine over USB to start the process. We used an Arduino Uno to control all of our motors (conveyor belt, release powder, release bubbles) , and used a Belkin Wemo smart plug and a companion Python API to turn on the coffee pot to boil the water (Python will send serialized signal to app, and then will call Python API. )
Challenges we ran into
We are not engineering students and design is hard (sad!) Getting the servos to works as we needed them and structuring the circuit to work accurately was a challenge.
Accomplishments that we're proud of
This is Diane's first hackathon! She learned a lot. Also, we finished this project. It's lit.
What we learned
Engineering design is hard!! Also Python is f**************** amazing.
What's next for Brewba
idk we need to return all this hardware (Sad!)
