This project is meant to be used by reloading hobbyists to automate the tedious task of sorting 9mm headstamps. To power the system, the power output regulates voltages with buck converters. A camera is used to take a picture of each headstamp which is then passed to a Raspberry Pi 5 that contains a custom trained machine learning model to identify the type of headstamp. The system also allows for user configurable accuracy. The headstamps are moved around the system using FS90R and SG90 servo motors coupled with an optical interruptor to ensure precision. The system is able to sort up to 5 different types of headstamps, each being done in under 8 seconds. On top of this, the system is able to be shut down in case of emergency in under 20 ms. Finally, the system features a system that allows it to swap between being battery powered and taking in power from the wall, depending on the needs of the user. In the future, it would be great to add a system that allows headstamps to be automatically oriented appropriately so that the user does not need to hand feed rounds.
