You've probably seen a recycling machines or reverse vending machines that accepts bottles and rewards you with some coupons or tokens that you can spend later or get a refund for some product. So, our idea was to bring together recycling and crypto. We decided to make a recycling machine where you can put different kind of bottles, and get a reward in crypto currency. Obviously, we don't poses this type of machine, so we made a Proof of Concept just to illustrate what we wanted to achieve.
This project consists of two parts:
We developed a service running on Raspberry Pi which uses a breadboard, some LEDs and buttons to simulate inserting the bottle into the recycling machine. Each button on the breadboard represents an inserting different kind of bottle: aluminium cans, glass bottles, tetra pak, or plastic bottles.
Technologies used: React, Node.js, Solidity, Docker
