It’s mind boggling how much e-waste we throw out. Perfectly good components, mass produced for pennies. And at the end of their life, going straight to a landfill or some poor country to be melted down. Don’t you wish you could help?
Stepper motors are a dime a dozen when it comes to e-waste, and there’s tons of cool projects you can do with a stepper motor — [Madivak] is just starting on a robot arm design over at Hackaday.io that makes use of recycled components.
It’s fairly early in development, but that means it’s a great time to start following it on the project site. The robotic arm is being designed for his final year project in his undergrad degree. Besides the steppers, he’s using his school’s Utilimaker 3D printer to manufacture all of the other mechanical components with control coming from DRV8825 stepper drivers and the Freescale Freedom KL25Z dev kit.
