Need some help with math.
I am working on a project, an electronic shooting target which should present·
a bullet hits the target, on a VGA screen.
My idea is as follows:
A rectangular target, at the bottom I have 3 microphones.
I have the prop measure when the bullet passes the target.
I am using 3 different cogs which simulataneous measures the time for the bullets "sound" when passing the target.
and got it to measure the distance from 2 of the microphones, the third microphone starts the measuremt (like a reference)
Now I need to calculate the angle of the measurements from the 2 microphones, thats where my math knowledge reach it limits.
I have included a figure of the mechanical setup and the Spin
I hope the attachment works
