The problem here is an issue of false positives. It would be a torso sized target attached to a mobile base. The issue gets more complex in that the base should be remotely controllable... Allowing for realistic engagement scenarios (a fleeing suspect, a dodging suspect, etc...) This means that not only do we have to detect the impact of the projectile on the target, but also billboard the target to the firing-line; always presenting the striking surface to the shooter. I was hoping to divide and conquer. Handle the detection first then the billboarding issue second.
I have setup a piezo element on a static target with the hopes that I can fire a few rounds through it and graph what is returned from it with an arduino... however weather and work have been conspiring against me. When it's nice enough to go shoot, I have to work and when I don't have to work, it's been hideous out.
So As I've been mulling this issue over in my head, I thought of something... ballistic chronographs (such as this one
). These devices detect the passage of a projectile between two sensors and thus cab calculate the projectile's velocity. Perhaps a similar sensor could detect the passage of the projectile into the face of the target... So now to figure out how those gizmos work...
