I like Haribo bears, at least some of them. Sorting them is a lot of work and that's why I made a Haribo sorting machine based on Arduino, some 3D printed parts and basic electronic components. It saves you a lot of time and makes the world a better place! It's not very sophisticated but it's definitely very effective. I would also call it overengineered and shitty :) Inspire by the work of awesome Simone Giertz!
