Hi,
I've been thinking about making a nerf targetboard for my son that uses 4 piezo sensors to wait until a analogue value increases over a threshold and then calculate the tdoa to get the position.
I've done a few tests with a 350x350 MDF board with each sensor 145mm from the centre point.
Is this possible to find the target hit point on a small area like this, or is there too much error to take into account when you are down to 100-500 microseconds between sensor readings? Im using a t4 with all sensors on analogread, but I'm starting to think it might not be feasible.
Thanks
