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 :)
