All:
Thanks for looking, I'm trying to determine the most likely path to go down.
Problem statement: "Patterning" a shotgun involves shooting at paper targets (or a steel plate with wet paint) and counting the number of pellets (~350 per shot) in a 30' circle, the center of the pattern is also determined by estimation. Since a series of several shots over multiple distances is required, this is a very time consuming task. It is also a 2 dimensional view of the shot. Shot actually strings out and impacts the paper at various times.
Proposed solution: Have the shot impact a plate and determine the location and time of the impacts. Calculate the center and other metrics.
Unknown: How to capture the precise time and impact location on a 3' by 3' surface without the sensor(s) being destroyed by the impact.
Research so far: It looks like Piezo Vibration sensors are used by the space station to measure impacts. However it looks like there would have to be a lot of them since the ones I've seen so far are fairly small.
thanks for any direction you can provide.
