Raspberry Pi for Kill Mosquitoes by Laser
- vinni2 6y agoTypo in the title of the paper makes me not want to read it.
- barbecue_sauce 6y agoIt gives it a "Borat-esque" quality.
- notsureaboutpg 6y agoBorat is a caricature of a Central Asian man and the author is also from Central Asia. Hmm
- vinni2 6y agoHow am supposed to know it’s a phrase? Shouldn’t it be in quotes?
- ColinWright 6y agoIt's a pre-print, made available early, and English is not the author's first language. I think you're being a bit harsh.
- vinni2 6y agoHow am I supposed to know the author is non-English speaker? Unfortunately it is true with at least academic articles typos and grammatical errors are it will be perceived as low quality article.
- jonsen 6y agoOne click on the authors name gave: “Mr. Ildar Rakhmatulin South Ural State University“
- ColinWright 6y agoThe academics I know ... and I know quite a few ... are understanding about people writing in languages other than their native language. Perhaps you should just go with your original thought and not read anything if you find any kind of grammatical error.
- Symbiote 6y agoWould you have preferred the researcher to publish in Russian?
- vinni2 6y agoNo but I am sure he has English speaking friends who could proofread it.
- hutzlibu 6y agoA bit of a arrogant anglocentristic point of view? Why do you assume everyone in the world has native english speakers as friends, willing to do free proofreading?
- kwdc 6y agoI found a bunch of people to proofread my work for free. Why would you assume everyone charges for everything?
- hutzlibu 6y ago"Why would you assume everyone charges for everything" Where did I do this?!? I know people who do this, but I know many native english speakers. People in russia for example might not have that opportunity.
- kwdc 6y agoYou wrote: "Why do you assume everyone in the world has native english speakers as friends, willing to do free proofreading?" So you didn't write that? Ok. The people who proofread my work aren't in my immediate circle of friends. My point is that you can find people out in the world that aren't in your current bubble. I have access to people now who speak and read more languages than I ever will. Some of them are in Russia. I think you are inadvertantly placing limits where they may not really be.
- ROARosen 6y agoDo you have any evidence correlating proficiency in grammatically-correct English and research quality?
- globular-toast 6y agoIt's not a typo, it's a grammatical error. It's a pet peeve of mine when people refer to any kind of mistake at all as a "typo".
- sokoloff 6y ago> More than 700 thousand human deaths I don’t think I’ve ever in my 40 and nine years on the planet seen numbers of this scale written in mixed numeric and textual form. It’s not like 700 kilometers, where you could at least argue this is the case vs the SI unit, but where a kilometer is a useful unit for communication anyway. The natural unit here is a human life, not a thousand human lives. There are a several other quality issues in the abstract making me wonder if this is a serious effort or a Markov-generated abstract. (“We developed a program for mosquito tracking in real.”)
- ColinWright 6y ago>> More than 700 thousand human deaths > I don’t think I’ve ever in my 40 and nine years on the planet seen numbers of this scale written in mixed numeric and textual form. In my 50 and nine years on this planet, I have. > There are a several other quality issues in the abstract ... It's a pre-print, and the author's first language is not English. Some people struggle with a second language, and I think it's commendable that someone is willing to make their results available.
- xbar 6y agoI like the author, the idea and the article. It will not stop me from highlighting one of my favorite clauses: "there are hundreds of different creams, devices, and other devices. "
- ColinWright 6y agoIt has the feel of being machine translated. A short time ago I saw an example of three different verbs in one language being translated into the same verb in English ... I'll see if I can find it. I suspect in the author's first language the first "devices" was something specific that got a generic label in English.
- Mediterraneo10 6y agoWriting numbers that way is common in various languages. For example, every day on the Polish news the number of newly detected COVID cases is written in the format "13 tys. 574", where "tys." is the abbreviation for “thousand”. As native-English-speaking academics have become a minority of those publishing in international journals (and fewer journals are doing serious copyediting anyway), there seems to be more and more toleration in science of different ways of writing things based on the author’s own native language.

- yholio 6y agoSo instead of having a mosquito bite, you now have a zombie mosquito attached to you continuing to suck and spill a large multiple of normal volume.
- souprock 6y agoThe conclusion is wrong. I personally witnessed a mosquito being made to pop by tensing a muscle. Note that I'm not claiming any specific mechanism of action, or that this is a common human ability, or that more than one species is vulnerable. I've seen it once. The case I witnessed was 31 to 35 years ago, in camp with a bunch of boys. To help you guess at the species, I can narrow down the location to one of three places. In summer of 1985 or 1986, it could have been in Oklahoma or northern Texas. In summer of 1987 or 1988, it could have been in southern New Hampshire. The boy had very well defined muscles and minimal fat. He got the mosquito to land right in the middle of his biceps. He saved his strength, waiting until the mosquito was almost full before tensing his muscle. The mosquito did not immediately explode; it took a good long time. Anybody else witnessed it? Anybody able to do it reliably? If so, can you describe the type of mosquito or where it lives or anything else that might identify it?
- helsinkiandrew 6y agoThis work (I think) worked with the mosquitos 30cm away with a servo scanning Pi Camera (1080p) and a 1W laser. To work in the real world - cover a whole room or terrace - presumably a much higher resolution camera (or much faster scanning system) would be required. Even a 1W laser is dangerous to eyesight, if it was being fired at targets mingling with people. The system could be mounted on small drones that would patrol larger areas - but the idea of robotic drones armed with lasers roaming around is beginning to sound worse than the mosquitos.
- jasonlenik 6y agoI agree, there needs to be multiple orders of magnitude improvements in HW&SW, as well as domain specific dataset development for this to work at all. I can imagine using a very accurate image segmentation algo to analyze the background and thereby prevent shooting lasers at vulnerable targets, but it's still hard to see how this is a good idea. A 1W laser is even more dangerous than you say. It is powerful enough to start wood fires.
- avian 6y ago1 W laser is in the “a diffuse reflection can do damage” safety class. It’s the kind of laser where you lock doors to the optics lab to prevent people without eye protection accidentally entering when the laser is in operation. Having a computer point-and-shoot one at random directions in free air is just madness. There is zero discussion of human safety of such a system in the paper.
- k_sze 6y agoI can think of an alternative, not sure whether that would be practical, but it's possibly safer than laser: instead of shooting laser, make a turret that shoots (biodegradable, edible) soap water at the mosquitoes, in the smallest dose necessary to make the mosquito's wings stick. It would require some fluid-aerodynamics and projectile motion calculation, however.
- momirlan 6y ago
- jasonlenik 6y agoAn interesting future application for computer vision, but until both hardware and software increase in speed and precision by several orders of magnitude, this is not feasible. Current neural object detection just isn't there yet. Not to mention the dangers of shooting a powerful 1W laser out in the open...
- Moeg 6y agoWhy not use sonar like the other such project which if memory serves is backed by Bill Gates.
- toomuchtodo 6y agoThe system designed and built by Intellectual Ventures uses lasers for ranging and discrimination. https://photonicsentry.com/ https://photonicsentry.com/ https://www.wired.com/2010/02/death-star-laser-zaps-mosqitoes-dead/ https://www.wired.com/2010/02/death-star-laser-zaps-mosqitoe...
- justaj 6y agoIIRC Intellectual Ventures was / is also a notorious patent troll. AFAIK this was the main barrier that companies that wanted to head into similar spaces had to face. So I'm glad something open source is being developed.

- njacobs5074 6y agoI would gladly don protective eyewear before going to bed if it meant having a mosquito free night. I absolutely hate the little fuckers with a passion.
- nsomaru 6y agoI find that the slight breeze created by a house fan is enough to throw the mosquitos in my room off. They find it extremely hard to fly in “turbulence.”
- sinuhe69 6y agoExactly my idea for a pet project for a long time. The only difference was my intention to use (ultra-)sound tracking as well.
- undecisive 6y agoHaha, I've had this idea rattling about my brain for some time too (though mine went a bit further in scope instead - all sorts of crop pest control for small-scale farming situations, such as greenfly, caterpillars, etc, with training to avoid positive visitors such a bees) Early on, I dismissed ultrasound - unless some kind of funky triangulation went on, I think the resolution would be far too low and risk of false positives too high - but I'd be interested to hear any thoughts you had on how that might work. That said, recognising the flight noises of certain bugs would make sense to me - only as a way to trigger a stop-and-sweep cycle though. But as much as the idea excites me, "real" exploration of the space will only happen when I get lots of time and a fair bit of money - and maybe some land! Alas, I'm nowhere near that point yet.
- ravenstine 6y agoThis is something I imagined as a kid. So cool to know others have this idea and that it can be a reality! (even if the results aren't perfect)
- markvdb 6y agoWhat about a triple beam setup? The individual beams would be only half or a third as powerful, making them safer to human eyes. Only where they cross they would carry enough power to zap the mosquito...
- Kliment 6y agoA 300mW beam is far more than enough to ruin your eyes.
- uuidgen 6y agoThis laser is 200 times too powerful to be considered "mostly safe" for human ayes (cat 3R) and 1000 times too powerful to be considered safe (cat 2). I toyed with the idea but it's hazardous in any usable setup. If you'd like to do it moderately safe I'd stay away from lasers. Use a power LED and parabolic reflector to make the beam as incoherent as possible and then focus it with optics to create very narrow focal depth. Then it will still be able to burn the mosquito but won't be a blinding hazard as little as 20 centimetres from the focal point.
- markvdb 6y agoI must admit I was just thinking out loud, not bothered by any relevant knowledge. Thank you for your thoughtful explanation.
- chrismorgan 6y agoIn Australia a laser that emits more than one milliwatt is a prohibited weapon. Your three 333 mW lasers are still vastly over this legal limit. (And Australia’s laws here were decided based on safety standards, the figures of which uuidgen points out.)
- willyt 6y agoNot all species of mosquitos are bad, e.g. there is only one out of 3500 that spreads malaria, some feed on nectars and are very important pollinators. Can this tell the difference between the different kinds? Or will the drones buzz around the garden lasering anything vaguely mosquito shaped?
- jccooper 6y agoA previous "mosquito fence" claimed to be able to recognize not only species, but also specifically female mosquitos, by wing beat characteristics. So it should be possible.
- ziptrees 6y agoI just moved to a property near a pond that is severely infested with midge flies and mosquitos. The water is supposed to be treated by the HOA but they've neglected it for a while I guess. A solution like this wouldn't work due to the sheer volume of insects in the air at any given time (millions gathering around my block). I rigged up a door reed switch that turns on high power fans for 30 seconds when opened that helps keep them out of my house, but I'm trying to figure out a better solution to actually kill them around the clock. Thinking of controlling an electric pressurized washer with a pi and spraying swarms with a solution of water, soap and neem oil.
- Salgat 6y agoA fan that blows them into a metal mesh filter is sufficient. The fan keeps them stuck against the filter until they dehydrate and die. Propane is often used to attract them to the fan but that may not be necessary in your case.
- dec0dedab0de 6y agoOne thing that helps is doing whatever you can to attract dragonflies. Planting bullrush is one way, I'm sure there are others.

- jacquesm 6y agoThis is a nice little firestarter. I've had this idea many years ago and my solution to that problem was to use two or more lasers of lower power that all shoot at the same point in 3 dimensional space. If you guess wrong then at least you won't set your house on fire (or blind someone).
- x86ARMsRace 6y agoThe FAA might take objection too. Some places won't let you have lasers within a certain range of an airport. Also, what happens if the mosquito turret mistakes a 747 for a mosquito? Sounds like an effective way to blind pilots. Cool idea though, might be fun indoors if your house is fireproofed.

- sillysaurusx 6y agoIncidentally, this was first posted to a clone of HN that I run. I can't link it here, or in fact even mention the name. But if you go to my Twitter profile, it's my pinned tweet. So if you like reading this sort of thing, perhaps you'd also like seeing it 44 days before it premiers on HN. It was certainly one of the more interesting submissions. It was kind of funny, because the author posted it a bunch of times. I think maybe they got confused that they were on the real HN, and were like "This is awesome! It's been on the front page forever!" and posted it more. Wish I knew how to contact him to let him know it's been picked up by the mainstream site. He also posted "Neural network for automatic farm control", their previous work: https://www.researchgate.net/publication/339105969_Neural_network_for_automatic_farm_control https://www.researchgate.net/publication/339105969_Neural_ne... They really love using neural networks for farming. Or for cannons. Either way, it's a worthy endeavor.
- simonebrunozzi 6y agoYou can't post if because... it has happened before, and caused trouble? Curious to hear why you're running a clone of HN, and why you assert that some cool stuff shows up there before it does on HN.

- hutzlibu 6y agoWell ... I think the person you replied to has a very troubled history with the staff of HN.
- 1MachineElf 6y agoI don't know why it cannot be shared here. Given the open source nature of PG's Arc and the fact that it's main repo comes with a HN clone, I'd be surprised if there was an impetus not to share forks of HN on here. But maybe the hesitancy to link the site has more to do with this statement on it's Welcome page: The initial impetus behind the site is a desire to try to recapture the early spirit of Hacker News. HN currently has about 5 million visitors a month. It's different than it was back in the day when it was a much smaller group of people.
- whiw 6y agoIf you do have to kill something then at least do it humanely. Burning them to death is pretty horrible, so is zapping them with a high voltage shock.
- michaelmrose 6y agoI think most people don't believe insects are complex of mind to be said to suffer in the same sense as human beings. Even if this is not so what is the exchange rate between human suffering and mosquito suffering? I would probably horribly torture any number of mosquitos to prevent the suffering of even one human. Wouldn't you? Can you imagine telling one person sorry you need to die I cannot justify torturing so many mosquitos?
- whiw 6y agoI'm not arguing that mosquitos shouldn't be killed. I'm arguing that one should not wantantly choose a painful way of removing them. Alternatives which could be better include natural predators, quickly squashing them, soapy water, soap film on stagnant water to kill off the larvae (but not where other aquatic life may be harmed). Just avoid the mean ways.

- labster 6y agoToday, PiNet. Tomorrow, Skynet.
- zw123456 6y agoOf course there are simpler ways of dealing with insect pests, but I love the hacker kookieness of it. But, an even crazier idea, get a magnetron from a microwave oven connect it to a phased array antenna (PAA), that way you can scan much faster. Also, use a reduced power and radar returns to detect any insect then activate the PAA to to focus the power of the beam to kill the insect. Much more impractical and dangerous.
- oblib 6y agoThese kinds of things are really just intended to be a fun proof of concept or a demo of something off the wall for shits and giggles. It's a bit of a leap to "You'll shoot your eye out" or "it'll never work in real life" because it was never meant to be anything more than that. Personally, I think it's awesome!
- mleonhard 6y agoI've had malaria many times. My friend's sister died from it. It is not a laughing matter.
- oblib 6y agoThat comment is so completely off the wall I'm just astounded. Nowhere in that guy's post about how to make this silly gizmo did he make any kind of claim about reducing diseases of any kind spread by mosquitoes. I don't know if you're blaming him for not preventing your friend's sister's death and you getting sick or mad at me because I didn't blame him. But your complaint does make me wonder what you're doing to solve the malaria problem?
- mleonhard 6y ago> These kinds of things are really just intended to be a fun proof of concept or a demo of something off the wall for shits and giggles. I interpret this sentence to say the mosquito laser is an unserious project. Saying that something is "for shits and giggles" expresses a flippant attitude. My comment points out that malaria-fighting projects are extremely serious, even if they are ineffective first version tech demos. > Nowhere in that guy's post about how to make this silly gizmo did he make any kind of claim about reducing diseases of any kind spread by mosquitoes. The paper starts out with: "More than 700 thousand human deaths from mosquito bites are observed annually in the world. It is more than 2 times the number of annual murders in the world. In this regard, the invention of new more effective methods of protection against mosquitoes is necessary. In this article for the first time, comprehensive studies of mosquito neutralization using machine vision and a 1 W power laser are considered." > But your complaint does make me wonder what you're doing to solve the malaria problem? This is a strange thing to say. You are implying that a person who thinks a problem is serious should work toward solving that specific problem. This is not true. There are many serious problems in the world. Each person must make their own decisions about how to use their time, including how much time/energy/resources to spend on themselves, on their family, and on others. You are employing a tactic called deflection [0]. You try to redirect attention away from yourself by criticizing me. This habit can harm relationships. I hope you can break the habit of deflecting when you feel criticized. Your life will be better if you stop deflecting. Changing habits is super hard. I have been struggling to change my own habits for the last 5 years. It's hard and worth the effort. Good luck and best wishes.

- hello_there 6y agoI wonder if something like this could be effective against grey silverfish? They move slowly, usually on the floor at night and they're big and nice for the camera to see.
- loxias 6y agoYou can do this with sound. A hybrid system even better. I built tech ~10 years ago to track quiet, sound emitting objects in real time to sub CM resolution using microphone arrays. And in one demo I even had a laser pointer mounted on a 2 axis.... "swinging thingie" (sorry, I'm not a mech-E) which would constantly stay pointed on the loudest object in the room, as it moved. Fun stuff. Creepy even. Shame I never found a use or a buyer for the tech. :/ EDIT: I bet an improved hybrid one would use sound to get within the right 1-2cm, with a zoom camera mounted on the pan/tilt apparatus to get it even more accurate.
- danielheath 6y agoMosquitoes can’t fly against a slight breeze. Under a ceiling fan is a 2m radius they cannot physically enter because their top speed is below the wind speed.
- npunt 6y agoI've been waiting for a commercial device to come out after hearing about this a decade ago. Some kind of simple blackbox that kills mosquitos in a reasonable vicinity with low power requirements that's also rechargeable via USB. Possibly add a big battery and make it a USB charger. I don't think 30cm distance is far enough for much usefulness, feels like commercial viability means at least 1m if not 2m. 30cm is 'put object by the food' use case and not much else, and mosquitos aren't really into food. Perhaps it could work by tent openings but not sure.
- simtel20 6y agoIn much of the world, 30cm is "put it by the bed at night and sleep without agony".

- mleonhard 6y agoThis is important work. An effective non-toxic indoor mosquito control device will eliminate much suffering and death. Malaria prevents Africa from developing to middle-class societies with stable populations and functioning governments that are able to control environmental pollution. Therefore malaria indirectly affects all humans. I think an effective indoor mosquito control system will detect mosquitos with microphones, aim with a zoom camera, and shoot mosquitoes with soapy water droplets. Soapy water kills bugs. The soap eliminates water's surface tension. Once the bug touches the droplet, it sticks to it. As the bug struggles, it gets pulled inside the droplet. The water blocks respiration, causing the bug to suffocate. For manual insect killing, a spray bottle with soapy water is far better than an aerosol bottle of toxic chemicals or a laser.
- vagrantJin 6y ago> middle-class societies with stable populations and functioning governments that are able to control environmental pollution I'm not entirely sure if this is sarcastic trolling or an actual belief of a sane individual but this, this is a load of garbage. So what, if Malaria gets solved the whole continent will suddenly have functioning governments and economies? Do you know how big the continent is? It's history? I hope you were trolling.
- mleonhard 6y agoI grew up in Ghana. I saw first-hand that women in poverty have many children but those with middle-class circumstances have fewer. Africa's population explosion [0] will slow only when the people climb out of poverty [1]. Total world population is half of the climate change CO2 equation. Malaria has an incredible suppressing effect on entire societies [2]. Many young children get sick with it monthly and miss school. Older children miss school to care for sick siblings. Parents miss multiple weeks of work every year because of it. And even after they're well enough to work again, they're not 100%.

- karlerss 6y agoI was hiking with a friend in northern europe. It was +25C and we were being harassed by mosquitoes, horseflies and who knows what else. Naturally the same idea occurred to us - to use a head mounted laser to fry the wings of anything that approaches us. We were joking about the bulkiness - that you would have a power hungry i7 on your head, doing live object detection, a heavy power supply for computation and a strong laser, servo motors whirring directing the laser. It sounds unjust - the forest being their home and couple of city-dwellers killing the creatures for a bit of convenience.

In the future, to increase the damaging ability, it is necessary to increase the accuracy of the laser operation. To implement tracking in the Python language, various algorithms were written, both with tracking at each moment of only one mosquito and using the multithreading function and transmitting data on the position of mosquitoes using an array to the galvanometer. The success of the experiment can be enhanced by using a more powerful laser, which will make it possible to neutralize more than 2 mosquitoes in one second.”
- garyrichardson 6y agoI live near the forest. Deer constantly eat our garden. I've seen motion sensors products that hook up to a sprinkler but I'd much prefer this tuned to deer with a water cannon instead of a laser.
- LinuxBender 6y agoThis is a neat project and a great idea. As a side note if you would like to dispatch all the mosquito in your area, there are "mosquito donuts" that are safe to put in creeks and ponds that will get rid of them at the source. For the existing mosquito infestations, a large blower flan with a window screen on the intake side will catch tens of thousands of them per day. You can mix their carcasses into your plant fertilizer. You can attract more of the mosquito to your blower by opening 2 litter bottles of carbonated water 20 feet in front of the intake side.

- TechTank 6y agoThis product is nothing new, and the reality here is that it's existed for quite a number of years. Why don't we see these things out there killing millions of mosquitos? Because the use of camera vision and a galvanometer to attack mosquitos with a laser is PATENTED TECHNOLOGY, owned and licenced by an Israeli company. You can find a Ted talk video where they display literally this same technology. So far, nobody has been willing to pay the astronomical amount of money they are asking to licence the technology and if this guy thinks he's going to start producing these things without a legal fight that will set him bankrupt, he has it coming.
