    Reminds me that comma.ai has its own line. While their setup is quite expensive they do run production for a smartphone-level of difficulty in-house. They detail it incredibly well…

    Had a chance to see a live demo last month. Looks great, can do a lot more things than an SO-101 and the teleop via the app if both fun and useful. Would definitely buy if I had th…

    That will end up either dangerous or unreleased. Their system sends a 40W laser, which is what you use to cut plastics. There’s no way to make this safe as even a diffuse secondary…

    Exactly! Plus we’ll get a nice beautiful sonar echo when they’re on walls/ceiling

    Long term, around $300/unit

    Unfortunately it won’t. an eye that collimates light is much more fragile to laser than a mosquito.

    Everything works in simulation, and the detection works in the real world! We’re working on miniaturizing the electronics to embed it in a real drone.

    Mosquitoes use different cues (olfactory, CO2 and infrared emissions/heat) depending on the distance to target.

    We could do something about it. Any flying insect is only a change of parameters for us.

    What do you mean by fidelity? We’re still unsure about the tails in terms of detection probability/false detection rate

    It might be, but it’s a crowded market where politics and connections are worth more than technical expertise. So, we’re okay to stay out of it

    Yeah, it’s one of our goal to work for government agencies at some point to implement city-wide mosquito control. 10 of our drones could cover a square kilometer, so we’d be a lot …

    Not our highest priority concern haha

    Their velocity is much lower than the one of the drone, so it wouldn’t make much sense to increase efficiency

    Yeah, you’re spot on! The original name was « mosquitorgnole »

    Just an insane obsession with ultrasound! (and some control theory classes)

    Glad to hear we could be of help! Some of our tech could be used for defense, but traditional defense companies and ukrainian startups already do low-cost shahed interceptors.

    Yeah, what they do is very cool. Not sure how far they are in the development but the videos are super cool.

    My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and gri…

    Light being coherent and light being dangerous are two completely orthogonal concepts. A laser is dangerous because of the very tight beam, but any household mirror keeps that beam…

    I may haven't fully understood your answer, but a typical household mirror could reflect 90% of the laser power in a single coherent direction. Any sufficiently polished metal tool…

    I’m not here to sell my own startup, but there are other ways to kill mosquitoes than a 40 watts laser that could make someone blind from a secondary reflection (out of the mmWave …

    They do in a YouTube video on their channel [0]. It’s 40 (!) watts. They also show it shooting indiscriminately at any small object, with an example where they feed it foam chips. …

    I’m interested in how to secure the firmware from reverse-engineering in a product. Is there somewhere an introduction to the techniques used by SpaceX there?
