Mineral is a touch-based interface for Computer Science House's drink machines using Gatekeeper for authentication
Most of Mineral was written in a weekend, during a 24-hour hackathon run by CSH.
Mineral is written in Rust using GTK 4 using gtk4-rs
# Usage
Mineral is installed on a Raspberry Pi living inside each vending machine attached to a touch screen and Gatekeeper NFC reader.
Users can approach a vending machine, tap the item they'd like, and scan their tag when prompted and their order will be dropped provided they have sufficient credits!
Note: Mineral supports listing the contents of multiple machines. This is used to allow Big Drink to be used for ordering from Snack which does not have a touch screen of it's own.
