Is it possible to tune this to specific frequencies to detect mosquitos? Their audio signal is pretty weak but its also a very specific frequency. This would definitely help in the hunting and killing of the little bastards.

Following Someone1234's comment[1] Stupid idea(?): Attach a mid-power laser to zap bugs, could even be a DIY project with an arduino and an PTZ mount. [1] https://news.ycombinator.com/item?id=29015202 https://news.ycombinator.com/item?id=29015202

  Just be careful not to blind yourself. Even a narrow flashlight cone could be enough for you to find and kill the bug by hand. Link to a previous post about this mosquito turret concept: https://news.ycombinator.com/item?id=27552516 https://news.ycombinator.com/item?id=27552516

    Exactly.. the laser introduces all kinds of safety issues. Simply shining a light and pointing me in the right direction vastly increases my lethality, especially combined with one of those fly swatter electric rackets. My cat would serve a similar role for larger insects. Her eyes would track them for me so I could locate and destroy them. Unfortunately she either cannot, or more likely chooses not to, track mosquitos.

No need for the hi-tech equipment for finding mosquitoes. Just take me to the spot you're looking, and they will find me.

If the mosquito frequency is less than half of the sampling rate of these mics, then yes. Very basically, these algorithms work by looking at the delay between each mic picking up a certain frequency, and calculating the direction of the sound wave from that.

Yes. One surprising result is that weak sounds, even some below the threshold of hearing, are easy to detect, provided you have clear line of sight and no turbulence.

A mosquito racket increases efficiency at least 10 times. If you direct the output of that camera to a VR visor you can chase and zap them in the dark.
