Same thought as well. They must not have done the math on the optics... You'd have a much better chance using an acoustic array (mosquitoes put out a very distinctive sonic frequency), or even better an array of radar modules. There is simply too much noise and data in the visible spectrum to catch something that small without expensive optics and an expensive processor to process all of those pixels.
- trulyme 6y agoThis. Acoustic array sounds like a great solution for finding that pesky mosquitto that is hiding somewhere in the room. Anyone know how difficult it would be to make this?
- craftinator 6y agoWell, you can get a radial acoustic 7 array of MEMS microphones for ~$50, doing stuff with the output is the hard part. That being said, I've used one to localisation the direction that lightning is coming from. Have no idea how good the accuracy would be, but there's likely large room for optimization in that setup; it likely just comes down to the accuracy of the microphones. I personally would go with the radar route; it's slightly more expensive that the acoustic route, but accuracy would be fantastic, even at a distance.
