eBay LED insect zapper teardown with schematic
HTML-код
- Опубликовано: 4 окт 2024
- A look at the circuitry of a generic non-compliant eBay insect zapper.
In hindsight I had already changed the original fuse in the plug, as it was a fake 13A fuse with no sand fill and one of the ends popped off when I took it out revealing that it had just been jammed on over the wire. At least the fuse was in circuit. The flex is probably the thinnest copper coated aluminium they could find, as is common with these products.
The circuitry is fairly standard, and the LEDs are running at about 12mA so they should last OK even if they are not going to be too bright. LED power is about 0.8W so not really going to be great for attracting insects other than in a very dark room.
In short - just basically what you'd expect of a grey import.

Did Clive release this video, take it down, and put it back up?

Photonicinduction once made an upgraded one, using more capacitors of slightly bigger size, operating at about 24 kV. The benefit was that it didn't need cleaning, it was self cleaning by vaporizing everything that was tossed on a grid.
As long as they don't mind inhaling atomized chiton (if they use it indoors, at least).
Shame he died.
His video's were awesome to watch!
As once popular he was, he has lost his place... guy has simply vanished.
@@BeezyKing99 he went through difficult times in his personal life, then he made a short comeback. Unfortunately he then vanished as you said. I liked his videos quite a lot.
Remember seeing a bug zapper in a Bakery in Austria - they had decided to go full on and had cobbled in a neon transformer.
Crunchy wasp bits on your Kuchen mein herr?
I gifted all my immediate neighbors outdoor bug zappers a few years ago. They all still use them and my property has remained bug-free ever since.
That's the best long term solution I've ever heard of!!! Genius!
Win win lose
You win because no bugs
They win because no bugs and neighborly gift
Bugs lose because they're dead
@@JessicaFEREM They win because the neighbors pay for the electricity! Plus, you don't have to have all those uv lights glaring in your face...
Genius...
And yeah, you gave all your neighbors gifts, so apple pies and brownies are sure to follow!
Pointless where i live basically in a field. We have all tried living rurally though it's a small price to pay
If you would have given them this one, there's a good chance your property would have been neighbor free :)
I have a rechargeable version of this, and they do work. The near UV won't attract mosquitoes, but it will attract flies and gnats. I use it indoors as we live next to Lake Erie and get an "abundance" of insects here. The one I have even has a bait cup at the bottom so you can use it to zap other types of annoying bugs as well. These things are a grand idea for indoor home use, to keep your house free of flying tiny pests, lol.
Yours is hackable as you can simply replace the LED strips with different UV wavelengths to see which ones attract the most insects. Now that would be a great idea for a video 😉
According to the HOPI display, it hit 1.9 watts when you stuck the screwdriver in to make it spark. Considering there's probably a high sampling delay on the HOPI, I'd imagine the unit does indeed ht 2 watts.
Ah, good. I was just about to note that. Well spotted, Bruce.
Thank you Bruce
Yeah, seems they were being slightly naughty about that. It should probably be using the LED power consumption, depending on the listing wording.
Last summer I bought an insect zapper from eBay and it was about $23 US. Since it's 120VAC, they used a HV coil with the windings split into four bobbins. It 's a lantern and uses the UV tubes. It works okay but not in daylight. I had to laugh when I opened it up and found the 3-wire cord's ground wire lug screwed onto a plastic post. 😱
The biggest treat in this video (for me as a person who watched tens of your videos on the topic) was the user manual read by Clive with serious face just as it was written in Chinglish.
I got myself some near-UV LEDs, and apart from curing clear resin, I'm gonna build my own bug zapper and observe if these lights help insects get familiar with the electrocution device or not.
Thanks for keeping our interest ignited!
Chinglish lol
And don't forget the yellow sticker.
Put enough capacitance across the output of the multiplier and you won't need to clean it ;-)
"Clean dead mosquitoes, flies and pets" Made me laugh very hard, i'm sure some families with a Christmas dog would love one of these.
LOVE your commentary and reading the grammar-challenged instructions!
This video is my favorite of your debugging videos. 👍
I like how they wrote, "To ensure safety you must connect the ground wine before use it" and then used a plastic earth pin
And there is no ground wine or wire either...
Yeah Chinglish😅
I always hear Ssh-chematic in my head now wherever I read that word. Lovely addition to the voices in my head! 😀
I think the neutral/live should be properly tested with the Flllluuuuke (maybe you did and I missed it?) There is no guarantee that they follow the correct color for cables so looking at the blue connected to the switch doesn't have to mean it's the neutral for real.
I have visions of Clive with a generator in a wheelbarrow, pounding the mean streets of Ramsey looking for flies.
Imagine that in a post-apocalyptic setting :)
Ribbed cable on a stick to hook onto the grid anywhere would be more on point.
This would be perfect in a Victorian setting. Instead of a guy with a barrel organ it would be Clive with his zapper hooking on to wires as John suggested giving demonstrations of his zapper.

@Keri Szafir How is your comment 3 weeks old on a video that's only 18 hours old?
Do you own a time travelling Delorean and can I borrow it please ?
I always enjoy the translations, they provide hours of entertainment if you've had a few beverages.
That looks like a perfectly reasonable unit. I really like how the LEDs slide right in. I’d turn it on its side so you could compare different colors’ effectiveness by the piles of bodies that accumulate under each.
I'm wanting addressable UV strips now RGBUV? Insect disco!
Maybe the 2 watts is when a bug is stuck in the grid and it takes forever for the stupid thing to kill it?
Your HOPI did read 2W when you were sparking it.
I bought such LED UV fly catchers 2y ago. The flys bursted out in laughter.
Having windows made „fly save“ and an electrocution fly flap helped.
I expected so much worse, given how DiodeGoneWild has had complete death traps every time he tries an insect zapper, such as the one with the self exploding UV lamp.
Fascinating to see what appears to actually be a compliant plug on it, UK plugs seem to be the most prone for getting things wrong with questionable electrical imports.
Countries which use the UK style plug often ignore the way it is supposed to work. Plugs often have no fuse at all, and circuits are wired at random. I was in a site office where one breaker tripped, and a section of the office lost power to sockets AND lights.
@@michaeltb1358 ... It's supposed to work? I keed, I keed.

And yet another 3-week-old comment
@@bartat404 Clive releases some videos to "members" prior to the general public?
Living in a tropical country where we have both regular mosquitoes and the black & white ones I can assure you that mosquito zappers are a requirement and make life more pleasant, though we usually use the tube light versions. They certainly kill off flying nasties and we have them on timers for all night use. I haven’t tried the LED versions but think they’re probably not too good
We actually use an indoor plasticy version of this at home near a farm. It was a last resort after fly paper and other remedies failed to deal with our fly problem. The LEDs do attract the flies but it seems to be far more effective at night when all the lights are out.
The first part of the circuit before the bridge a transformerless voltage reducer. It used often in LED power, cheap but it works.
There a special satisfaction when a wasp flys into a zapper. As it is burned to a crisp. One less that can sting you.
Yes would appreciate a follow up on how effective it is. Have a dozen of the fluorescent types in factory and tired of changing starters and bulbs. Thank you Clive!
Having bought and tried an LED bug zapper, I can confidently say that nothing seems to be attracted to the thing...
Went back to use the bulbs.
Thanks for confirming my suspicion
@@25566 i tried a little plug sized one with leds, nope, nothing went near it
I have a cheap bug zapper here in Melbourne, Aust. After a wet 6 months to December, we had a plague of mozzies everywhere. I dug out the zapper and set it outside the back door alcove (under cover) where there were swarms of the buggers. It definitely attracted them and also moths of various kinds, but no flies. I think Aussie flies are smarter than any others in the world, haha. Many sounds of gunshot zaps all day and night. I don't think the mozzies make a sound, but the moths crack up pretty well :)
Reminds me of a dodgy pizza shop in central Australia, they had an old fashioned bug zapper with a pair of 18watt semi black light tubes set up in the pizza making area right above the bench where the delicious pizzas were assembled. I remember going in on a hot summers night to order a meal and the bug light was crackling away due to swarms of flying insects drawn in to the light, I can still see numerous zapped bugs of all varieties and sizes raining down onto that bench and no doubt becoming extra ingredients on top of the pizzas just before going through the ovens!
I use a similar one, with UV (or near UV) neon lamps. Here in Italy, during the summer, it makes a whole lot of difference. Sure, there's that recurring popping sound, but better than being stung all night.
Aside from the obvious and also mentioned, one of my favorite things about this channel is hearing you say “oout-pout.”
Interesting and lethal (to everything), what more could you ask? I await part 2 / demonstration (early Shango-style, with the sound of you drinking ground wine in the background).
I have a tube based one here which I bought last year. It really does collect insects rather well and I regularly hear it giving a jolt to unwary flies and moths. I actually bought several and to be honest they do actually work, regardless of how cheaply made they are.
Nice one Clive, very pretty.
Elegant schematic, not seen it layed out that way b4.
;)
Oh no! Neither me nor Fran can take it apart! :D
Nice, simple circuit here.
Yes. It's a very sexist zapper. But it's OK, because you and Fran are defiant of authority.

My dad in his youth made a bug zapper that he hung from the lounge light socket…
…all was well until his dad came in and wondering what it was, touched it 😂
dad zapper .
It does amaze me that after all these years Chinglish hasn't noticeably improved.
I just want the LEDs 💜
although I suppose I could have some fun with the HV bits too
You make a simple thing as a video of a pest killer interesting. Nice work!
i have a very similar unit, just much bigger with metal at the bottom and top and 2x 60cm T8 Fluorecant Tubes in blue. The tubes are in Series with a traditional ballast, and there is a 2000V 9mA Transformer in the lid on top too for the high voltage. Ballast is under the top lid as well
Due to an extremely annoying potted plant tiny fly infestation, we have quite a few of the annoying in your face tiny flies flying around the house. I bought a 5v USB powered version of one of these in a cylinder shape. UV LED's in the top that are dim like the ones in your zapper, it still attracts the flies and despite being 5v still gives a loud pop and enough voltage to make the flies explode. Quite amusing to watch after one has just flew into your eye and then the zapper
flown 😉
Fungus gnats. Very annoying!
Nice ter down Clive it looks fairly well built !
It's 2W peak when something gets zapped. 1.1W is standby consumption. Grounding the anti-touching grid makes safety sense, but someone removed that after they bought the labels.
Ground wine? well I figure that would be very dry. 🤦♂ They could do with cleaning up the tracks on the board and remove some f the holes. Over time they would save a penny of two. 👌 A nice spicy bit of Chinese's zappyness. 👍👍
In hotels it is used in the trash bin room.. (Trash in hotels in germany at least are supposed to be in a cooled closed room to minimize odors and development of ant, fly, maggot tribesvthat could revolt over the living conditions
That may work well outside. Thank you for your teardown.
There's a very old entry in my brain's database that recalls the bugs are chiefly attracted to blue light. That's why yellow/amber outdoor lights were all the rage in the 80s and 90s. Bug zappers only used UV lights because the clear quartz lamps were the efficient way to generate that blue light in those days. (In hindsight, it's a wonder I didn't give myself welder's eye looking at those!) It would be curious to play with the luminescence and color of those LEDs to find out what's more effective. Presuming my memory is accurate, I'd bet a blue/cyan LED would do a better job.
I don't mind when the speaker pops. It's when the ears under the headphones pop I mind 😁
I would expect the missing components on the PC board are there to add an additional voltage doubler stage for use in the US.
Might go find one of these LED near UVs. My fluorescent zapper in my home collects everything but flies. I have dark-ish walls so the fly chase is a couple day adventure.
I would think a bit of rotting meat would be more effective at attracting flies than those LEDs! These things need a CO2 generator to attract the flying nasties.
I know mosquitoes are attracted to CO2, so that's correct. I'm not certain how well that works for flies. In the past, we got pheromone strips to attract flies. I don't know where to get those today. UV alone (even from a BLB fluorescent tube) were documented as not effective against flies. There are some commercial units that have a blue glow emanating from them, but only as indirect light, so I suspect they use UVC tubes to do all the work. As for their fly attractant, I have no info.
@@mikecowen6507 The rotting meat will attract the flies 🤣- and yes the CO2 is to get the mozzies and those darn irritating swarms of midges 😂
I modded an old one from the 80s where the hv had died with a neon sign transformer. Let’s just say anything that comes near the grid don’t stand a chance 😂
Thanks, Clive 😁
oh nice I bought one of the fluorescent tube ones a few months back and it was a bug killing machine, but the tubes went out and trying to replace anything was proving more expensive than the unit. here's lookin' out Big Clive
Clive this may be a great appliance for another episode of "Cooking with Clive" some canned meat product being zapped continuously till golden brown
I somehow have a feeling that flies won't be attracted to LED's as much as old fashioned fluorescent tubes.
I have a similar-ish size and shape of bug zapper that uses the fluorescent tubes as a "black light" uses, and it works quite well for occasional indoor flies, mosquitos, and even occasional moths.
We have several of them at work, They are actually a legal requirement in food production.
we have issues with flies in the summer months and tried an upright mains one with UV tube, nothing, empty, they didnt go near it ...
@@andygozzo72 Hmmm... I don't know about your specific bug zapper only my own, and unfortunately, I can't accurately measure what nanometer frequency of the purple-into-UV spectrum of light my bug zapper is emitting, but there's nothing other than the light to draw the bugs to their eventual electrical oblivion...
I wonder if different manufacturers have slightly different UV fluorescent tubes with slightly different frequencies of purple, near UV, and proper UV spectrums of light coming out of them.
But I like my little cheap-ish "LiBa bug zapper" as the Amazon listing called it, but there are of course plenty of same-ish ones on there with different brand stickers on them. I've had mine a while and I think I only put $20 or $25 into it to give it a try. I'm pleasantly surprised with the years of service I've gotten out of even the first set of bulbs, although I only use it occasionally of course.
Rodalco will be watching this intensely.
Last time that I know about where anybody published a paper about this the results were disappointing to say the least. I don't remember the exact numbers but of the thousands of insects killed, only a few were mosquitos and only a few of those were female. Entertaining, yes; mosquito killing, not likely. Thanks for the videos. I have that paper somewhere if you would like to see it.
My worry about most zappers is that they attract the wrong insects.
Mosquitos and gnats are attracted mainly by smell and CO2.
It’s the innocent moths that are getting zapped ☹️
A lot of the new zappers have attractant pads to bring in the mosquitos. They still havent solved the moth killing problem though.
Those innocent moths once ate my best suit
@@michaeltb1358- clothes moth ~ we had those eating the carpet in our lounge
Thanks for the great video Clive 👍
I once had left the lights on while opening the window in by bathroom after a late-night shower in summer. When I came back, the room was full of little... I guess they were fruit flies? Something like that. I macgyvered together a cheap insect killer by gluing a single blue LED in a transparent cup, filled with soapy water. Next morning, the cup was black from hundreds of dead mini-flies. So I think the LEDs might actually work as insect attractors. Doesn't even have to be near UV, normal blue will probably work as well. Not sure about the gaps in the mesh though. They seem pretty wide.
The real ones have tilt sensors, and fly catcher tray interlocking, I pulled a real one apart because the sensor had corroded.
Well, it's no "Electron go out mosquito Small a night lamp", but really, nothing else is.
"and pets"
I picked up a few old zappers with blown tubes, I got some 2 amp 12v transformers that I wired in place of the ballasts and ran some lengths of that "almost 400mn LED" strips along some scrap conduit (on the outside lol) that wedged in place of the tubes. they work well but I should have used more powerful LED's for the brighter part of the Australian mid-summer days lol. It has cost me under AU$10 each to convert them using parts sourced on-line from AliExpress. I have ordered a strip of 5050 LED's to replace the 2835's currently in use.
I think it hit 1.9W when you zap it so maybe thats why they called it 2W?
I can't imagine any bugs that you would find pests being attracted to the light. Moths and beetles would be, but I doubt flies or mosquitoes would.
I read somewhere that mosquitoes are mainly attracted to carbon dioxide and not UV light. The pathogens that flies carry tend to get spread into the air when the fly gets vaporized.
@@myofficegoes65 Without an added attractant station (blood/old meat/offal for flies etc) they would be very lucky to get a hit on flies, mosquitoes or sandflies. However when hung outside under the eaves and powered from dusk to dawn they can significantly reduce the summer invasions of moths, beetles, flying ants and gnats that may plague your evening lights no matter how secure your house has been made. The tube type work best and are easily cleaned with compressed air or a leaf blower.
I love chinglish it’s so funny brilliant tear down Clive it will be nice to see if it actually works thanks for the video
Those speaker pops coming through my 505W subwoofer are really gnarly :)
So if only the "men" can work on it are the rent-boys allowed as well?
They are quite peaky. It makes you realize how loud a spark is
Can't imagine what my 1800w sub amp in my basement would do... I watched the edge of tomorrow on the setup and the intro trashed an 18 inch sub O.o
I *LOVE* the translations from Chinese. Or Japanese, for that matter. Very entertaining!
chinglish
@@amojak THAT'S it!!!
I have a couple of these in a similar vein... they do work quite well, I've caught some very large moths and even a giant grasshopper. Multitudes of smaller insects as well.
The pitfall I've found: There's not enough isolation between the high-voltage grid and the LEDs. So that if/when the unit catches too many bugs or inevitable dust the high voltage can jump to the LED strips and cook 'em.
Thanks as always, fun stuff. Cheers.
I bought a cheap assed sandblaster a few years ago and it had a proud looking sticker on it that claimed it was "Made In Chian"
Such thrills. Much excitement.
Ground wine! Refreshing!
Good for mosquitos and some other flying bugs, but useless for flies. We have similar units in Australia and the ones for flies use an attractant, a powder mixed with water, to attract flies in a tray at the bottom of the unit. I thought any flies would freeze to death in the UK 🙂
According to an LED Expert website, insects are attracted to 300-420nm, so you should be ok, Clive. Maybe another video when you test it?
Fun fact - the English word "tension" literally translates as "potential" (in reference to voltage) to some languages.
My attitude these days when working on, or just messing about with anything is to pull the plug. Then before doing anything exiting with it, look at the unplugged plug. or have it your (white lab coat obviously) pocket.
I was wondering if the Neutral actually went to the blue wire that was showing, if it was the live then the switch would actually be switching the live. Therefor two wrongs making a right.
"...so DON'T take it in the bath with you..." GOOD TO KNOW!!
I bring mine with me in the shower every morning. Should I stop doing that? 🤣
Nah mate you’ll be fine, Ive got four of these and place them in the corners of my hot tub these kill two birds with one stone they provide excellent lighting and kill all the mosquitoes and moths.
*in Christopher Walken's voice* "Mmm.... Needs more capacitors."
When you try to kill some flies this summer it would be interesting if you tried different light to see which attracted the most bugs since it appears east to modify.
Do you power it with electricity, from the National Glid? 😁
So what's the recovery rate? I live in the Deep South of the United States. Our National Bird is the Bald Eagle but I think the mosquitoes is more popular answer here.
We go through at least 2-3 bug zappers a year. cost us about $50 each. They all burn out and stop working.
I had one that when a bug touched, it took what seemed like one second to recharge before the next bug would be zapped blowing off their wings. Is there anything I can do to make them last more than a season. One zapper takes about 2 months to fill a 5 gallon bucket up with mosquitoes, beetles and other winged insects.
I thought it was due to the high humidity so I sprayed the boards with Conformal Coating. Still got the same results. They are outdoors but under a roof away from rain and direct sunlight. The lizards and frogs love sitting under the zapper each night.
Just a thought but I have (well the wife bought) some yellow canvas deck chairs, now they attract midges like mad, put a blue one next to it and they ignore the blue one and just cover the yellow one, just a thought try yellow leds instead and compare results 🙂
Public Notice, No flies were harmed in this video!
You sent this to AvE right? right? Cause he's gonna love this level of chinesium!
It looked like when you shorted it the hopi showed 1.9W maybe that's what they were talking about for the 2W claim?
A wet (e.g. licked) nylon cable tie is good for getting an angry response from the bug zapper :)
Obviously don't hold it by the wet bit!
You should get another one and swap the LEDs for another color and put them both out and see which one collects more bugs!
I'm supremely disappointed that they won't allow me to take a bath with the high voltage insect zapper. And here I was hoping for a little buzz in my life.
Cheap thrills.
2:20 Bloody hell, there are supposed to be dead PETS on this thing as well...?!? :P
I'd say diffused white LEDs would be more likely to attract anything.
mmm ground wIne - the best form of wine!
Bug zappers (uv) don't really attract mosquitos at all, you need some kind of bait for that. They are attracted to CO2. What the lights do attract are moths, which are usually considered "Good" bugs you don't want to kill.
Having had an issue with indoor moths in the past, I'd be happy for them to be attracted to the unit. Outdoor moths are fine.
I get quite a few wasps in the workshop/attic in summer, and I’ve noticed they’re attracted to my Gallium pcbs and USB trees; so I’m thinking of buying a zapper and replacing the leds with RGB ones….
I wonder if it's the moving pattern of light.
Wishing you a happy Burns Night. Oh chieften of the dodgy electronic purchases.
The old ones and flowtrons, use just a beefy transformer and a neon bulb to be the flourscent tube starter, which you can swap out for a proper starter, I find the transformer ones more reliable
I have bought something very similar two years ago. Firstly, not effective on mosquitos - as these do NOT react strongly onto UV. Mosquitos go for CO2 and smell. Second, if you have that overnight getting the attention of a moth or fat fly, it makes a sound like a 22 shot going off and having it burned down with arcs and a really awful smell.
Cannot recommend it unless your issue are moths and flies rather than misquitos. Have mine with a timer only switched on for 2 hours before bedtime. So if there are flies and moths, thats it. No need to illuminare a bedroom with LEDs and being woken up by a big BANG in the middle of the night.
