Arduino Bullet Casing Sorting Machine
DIY Hacks

  Having your technology save you time is great. NYC CNC doesn’t have to sort his spent bullet casings any more since he has built this Arduino Sorting Machine. It has an automatic feeder which drops the casings onto a roller, the roller opening is slowly enlarged until the casing falls through. The system then sorts it based on the size.
