Let's Make Robots!

Device "X" ,determining the direction of incoming gunfire.

Its not done yet, a picture is worth a thousand words :)

Ill try to provide more info when done.

the PCBs are home made, i regret not routing some pads for the wires as it would have turned out neater.

PS: it's placed with the "robots" not with "something else" because it classifies as a robot, if you feel that it suits the "something else" part more feel free to move it there :)

I think that the reason for the uninsulated top is to vent the cap in case it is polarized wrong or outside recommenden voltage specs.

Many of the also have the fracture line to open controlled.

That is absolutely correct, but in my case and if you look at the photo, the capacitor did in fact explode, not vent.

Have you considered using the frequency/sound of the gunfire or amplitude to try and determine the gun that shot it/how far away it is ?

This is just the prototype and a quite dumb proof of concept. any further model will be based on an SBC "Single Board Computer" to do all the analysis and a lot more.

What I think you have made here ,is a board with a  directional microphone that dedects the sound  flying objects do

as they move through air.The role of the four microphones is to dedect from which side the object is comming by reading them

simultaneously and by comparing the values its one gives.

Am I right?

The sound that i want to detect is the gun fire sound from the source. Not the bullet itself.

the second portion is correct, it does compare the 4 and gives out a single direction which is the most close.

next model would calculate the intensity from the 2 most powerful signals and determine exactly from where its coming.
