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$

    I feel like the physics behind attaching shotgun shells to your helmet with the intention of shooting down drones would break your neck.

      Just attach downwards facing blanks that trigger at the same time.

      With no barrel to really direct the velocity, wouldn’t it be more like attaching a tiny grenade or firecracker than a bullet? In that case the kickback force would be less than out of a regular rifle since the blast velocity is distributed in a radius and not in a singular direction.
