Saying non credible af here, but in theory one could add a upwards facing shotgun shells on top of the helmet, triggered by a Camera/proximity sensor if it detects a drone/falling grande. Maybe add a gyroscope to check if the helmet is actually facing upwards before triggering. All in all unit cost could be below 250$

    Bird shot doesn’t hurt when it falls on you, unless it gets in your eye. The recoil from the shot might be enough to cause serious neck damage.
