You have to make the blue lights light up. Not hit all of them. You can't go over or else the traps turn on.
As for annoying, I thought it was a cool puzzle. First I thought, shoot all the resonators. Then I read the journal and it cleared everything up.
Yeah, each one has a certain value and you need to hit the ones that add up to exactly how many lights are on the big center circle. Trial and error, my dear boy, trial and error.
