    So I can either set up an expensive machine that will make my electricity meter spin like a helicopter rotor while being a major safety hazard to life and, even if it works only as intended, fill the air with a constant supply of mosquito smoke (don’t breathe this!) or I could just get some of those curly sticky strips from the dollar store.

    This is neat but also stupid. If a laser has enough power to fry a mosquito, it can also fry your retina.

    Yes, I’m aware he added a safety system. That’s one layer of Swiss cheese in the safety system. It’ll work flawlessly until it doesn’t. How are potential reflections handled?

      Could run it similar to those disinfecting light bulbs (only when the room is not occupied)

        How do you ensure that the room is empty, 100% of the time? Those disinfecting light bulbs don’t have the same level of risk as this laser system.

          Perhaps a second laser defense system can be installed to ensure people stay out of the original room?

          Have it spray tear gas first. But wait, then the laser won’t be able to penetrate the cloud. Maybe we could add a quadcopter drone to clear a path to the mosquito for the laser to fire. But then we’ll need a system so the drone doesn’t run into a human choking on tear gas, and the drone can’t see because of the limited visibility, could we use infrared sensors I wonder? /s

          This is a stupid system. I love engineers, but they tend to uh… overengineer things like this.

            I think we’re overthinking this a bit. I have one simple question. Hear me out. Can a mosquito survive a nuclear blast? I’ll let you sit with that a minute.

              “Nuke it from orbit, it’s the only way to be sure” has always been my policy for spiders, mosquitoes and ticks, so I’m looking forward to World War 3 going nuclear. I’m just a bit concerned that the “from orbit” part implies I’m supposed to be up there when it happens, and while I understand the basic mechanics of how to get there, I’m not sure how I’m going to handle the logistics after that point.

      I don’t think a reflection would be coherent enough to carry enough energy to cause damage.

      Personally, I’d just wear laser goggles while the system was operating.

        It doesn’t need to be coherent, just needs enough joule. The prior commenter is right, if it can fry a mosquito even a reflection will damage eyes

    Mosquitos are always landing up on the ceiling, you could just mount it above eye level with hard stops preventing it from pointing down, make sure you don’t have shiny ceiling things, and it’s safeish :P

      When light encounters a surface, a certain amount of it is absorbed, some may pass through the material, and the rest reflects. All of those functions are variable with wavelength- a material that is opaque to visible light may be transparent to other forms of radiation, like radio waves. This is actually where our perception of color comes from- it is the wavelengths of light that weren’t absorbed by and didn’t pass through the surface we’re looking at. (Sorry, I’m a nerd about this sort of stuff)

      A laser is extremely concentrated light. Most materials can only absorb a certain amount of that energy. As such, a lot more of it reflects back off the opaque surfaces it encounters, even if they aren’t mirrors. For a strong enough laser, even that weakend reflection can do damage.

      I’d just stick screens on one’s windows and maybe use DEET if you’re really at the height of mosquito season in a bad area.

      Like, this has a DSLR camera, a GPU constantly churning away, a laser…

    Depending only on a second vision system as a safety interlock seems… foolhardy, to say the least. A laser strong enough to instantly fry a mosquito is likely also strong enough to instantly make you blind.

      This idea was tried previously. If done right, it doesn’t take much energy to damage a mosquito’s wings.

      Secondly, a laser is only a real issue for vision if the eye focuses on it. With a continuous beam, it would be instinctive, making it dangerous. If the pulse is short enough however, the eye won’t have time to focus and so the power will be safely spread out, even inside the eyeball.

        Per a quick search, 500mW is the threshold where a laser can start doing damage faster than your blink reflex and reflections are also dangerous (IIRC this is the bottom end of class 4 lasers). Most of the projects I’m finding online that are similar to this one are around 1W, so double the threshold.

        That’s not necessarily the “instantly blinding” territory I suggested, but even a short exposure will cause damage.

    I’m highly skeptical of this thing’s ability to detect and locate a mosquito in 3d space over any kind of range using pictures of mosquitos on his arm as a training set.

        AI: “Great news! I’ve found the mosquito! I’ll shoot it with the laser now.”

        Inventor: “Oww! That was my arm!”

        AI: “You’re absolutely right! My mistake. Let me scan again… Okay I’ve definitely identified the mosquito this time! Shooting laser now…”

        Inventor: “DAMN IT, THAT’S THE EXACT SAME ARM, AGAIN!”
