After wasting my time watching 15 videos useless on youtube how to upgrade my mouskito electric racket, I found this one and simple and usefull !!!! Thanks !!!!!
Sometime when you hit them they don't stick in the racket. You see/hear the spark but can't find it. Then it's back flying around. I need a one hitter quitter.
Just bought 10 of these in the local store for £2 each, i only needed one, but the things you can do with these and the tech inside for just £2 is a no brainer really...you can create some really sinister projects that people find shocking...Literally..
Get it? "Shocking"... cuz like, there's electricity, that shocks stuff, and there is a colloquial euphemism that English speaking people say, that for example, could go something like, "I'm *shocked*, that you intentionally set me up for failure, via some dastardly electronic prank device that you soldered and superglued into existence, and rigged to a fully charged car battery." Or another, somewhat more illustrative example: "When said evil device was utilized in its intended fashion (upon my "hapless, gullable ass" as you once remarked), my central nervous system, went into a sort of misfire sequence, catalyzing the indescribably explosive, depressurization and violent evacuation, of the 22.7 OZ (Troy OZ) of aqueous, tar-like, proverbial microbial "death-N-rot Rave" of putrefaction within my bowels (that of which 1 day formerly, existed as the constituents of seven and ¾ Taco Bell Chalupas™️), at which time I of course dropped my trousers/underwear, in such a way that they rolled off of my legs and were now inside out. Having done so, I ran shit covered, naked, screaming, crying, and yet laughing maniacally, as I nimbly trounced and sprinted through the entirety of your humble abode. All the while during this psychic shattering of mine, for the best part of a half of an hour even, I raced, spinning my now spent and wasted pantaloons, held by the very bottoms of the pant legs themselves, in a psychotically perverse, rapid, helicopter or propeller type motion, raised above my screaming, raving, fecal smeared head. In being "greased up" as so I was, slippery-slick! And almost frog-like in the way of my texture... Along with hitherto scientifically unrecognized and or known of terpenes, oils, and delicately cultured fragrance factors, familiar only to those of whom design and produce the very rarest, finest, most exclusively limited perfumes, often for sale to unspeakable eldritch horrors, and demonic beings from hells seventh layer, I had quickly become a worthy (and rather wiley) opposition. Either to being verbally arrested, or physically "wrangled" into any semblance, of non-schizophrenically dashing and whirling madness..... You, my friend.... Were quite *shocked*......" See? Cuz he got shocked? By electricity? AND he got surprised! They both did! HA!
Is it possible to electrify insect window screen to zap mosquitoes that are trying to get at you? I was looking out my window one evening and within minutes there were dozens of mosquitoes attracted to me exhaling CO2. If it weren't for the screen separating us, they would have feasted on me. I would love to be able to watch these vermin roast as they attempt to get at me.
I had several of those zapstick stun guns laying around, so i gutted one of them, as well as my flyswatter. Then i simply transfered the stun gun "insides" to my flyswatter, and upgraded to a 9v battery. The result is extremely effective at killing any bug ive needed to kill, particularly paper wasps. And whats nice is that i can hold the button down and get a continuous zapping effect, as opposed to having to press the button over and over for each "charge".
Nice..... but, A capacitor in parallel adds its value to the value of the capacitor already in the swatter. This creates a bigger spark But the fly swatter remains under tension for minutes after letting go of the pushbutton. Therefore, a discharge resistor must be placed across the capacitor for safety. I think 22M 1/8 watt is enough (red red blue) I also wonder whether the electronics can withstand the larger charging current because the capacity has been increased. The voltage on the red wires outside the swatter is about 2000 Volts so the insulation of the wires is questionable. It is better to keep the capacitor inboard, there is enough space. Also do not cross the wires inside to the wire maze on the outside but run them parallel to the capacitor leads to avoid a flashover between wire end capasitor. Who I am? I'm a technical engineer at KEMA, The Netherland.
This is really awesome! Thank you for this video. I live in Brazil and I definitely need a more powerful zapper. ALSO: Has anyone made a "traditional" bug zapper out of one of these rackets? The kind of bug zapper that has a light in the center and the insects fly to it and get zapped. One of my rackets broke and I was thinking of rolling the screens into a cylinder/roll and putting a light in the center. I think it might work, but not to sure, because when you hit the bug with the racket, there is a lot of force that causes the insect thru the first screen and into the second screen. Maybe the insects won't be able to kill themselves properly by touching both screens at the same time. LOL.
Hollie Garner I’ve added one capacitor of 2 kv (actually the same as the original one. I got it from a spare swatter) in parallel. But I don’t notice any difference...? Actually it seems like the swatter had become less powerfull
I think it’s so funny how you can find videos on RU-vid for anything and I never contribute but thank you so much for uploading this video. My bug zapper stopped zapping but while I’m at it I might as will super charge it. I wasn’t positive how to test it without hurting myself either I tried dripping water on it and I didn’t do anything but I wasn’t sure if it was because it was broken or because I am broken lol
Hi Chich, Thanks! Can I add the capacitor to a 120 VAC rechargeable swatter? I imagine it has a rectifier circuit and dc battery, the rest the same. Thanks, Gus in Caracas.
Terminals match up nicely with 9v alkaline…would it be hard to modify this so that increasing input power from 3 to 9v wouldn’t damage it? What would that do to the high voltage output which is currently about 3-4 kV, I think.? Thanks.
@@chich7089 I've noticed, an electrolytic capacitor of this value only charges to around 475V, standard it reaches 840V. So I added a couple 275V film capacitors instead so it still reaches it's 840V. Namely I have these three now in it: xgd-x2 mkp (standard), x1 ckx 824k 300v and a ps105k, both of those out of an old broken PC Power supply. It works and cooks more but since it's the same voltage with the double AAs it doesn't zap better at all, only cooks better.
@@Shishou_Shi You should not charge a capacitor to a higher voltage than its rated limit. The 400v capacitor probably got to 475v before it was damaged and began to conduct, limiting the voltage and wasting power. Better to use capacitors which are rated to handle above what voltage they'll be charged to.
@@dancoulson6579 well the standard film capacitor was a 275VAC one, so what does that say about it? Electrolytic capacitors don't work for this application anyway. Since the two capacitors I added exceed the limit of the standard one I think it should be fine but I did remove the resistor that technically lowers the voltage.
Sure, it's not a complicated circuit. Just step up the voltage to about 3000V or more and use it to charge a capacitor that you make as big as possible.
How did you know that the earlier capacitor was burnt or broke, that you went straight to the old capacitor and replaced it ? What was that you found that identified the capacitor was the culprit ! Nice video and very informative.
❤ I Prakash Sharma from Bhopal (India), also added extra pf capacitor in parallel but not increasing output voltage from 500 vdc to 1k vdc which is extremely necessary to kill mosquito. Please suggest solution.
I live in Arizona, we've got a lot of the same annoying, sometimes poisonous, critters running around that you do in Austrailia. What size was that transformer you used? What do you think would deliver more punch, using batteries with higher voltage or ramping up the transformer? For a big bug killing zapper, do you need a new capacitor also?
Hi Chris, the tranformer is the standard one fitted to the bug zapper, I'll do a video later and I'll be increasing the battery voltage to see what the zapper will do. Some extra capacitors will be added as well just for the fun of it. Good luck with your critters!!!
Don't understand how you could use caps rated at only 300-500 volts (as described in some of the comment replies.) Isn't the secondary creating something like 2 or 3 KV (I know it's DC, but its still in the kilovolt range)? Seems like those capacitors would break down at that voltage.
Well i think he looked at what capacitor originally was inside and since it not breaks down it's voltage is okay. But maybe some not so honest manufacturer made it cheaply by putting inside capacitor without voltage reserve, and it's not good. The best way is to make a measurement through divider.
If I cut one of the yellow wires trying to remove the top metal mesh ( I didn't know it was attached to it under the plastic handle) can I bridge it with the other yellow wire?? Will it work??
@caniborrow20dollars I don’t want it running 24 hours per se but want it to start working automatically the next morning. The bug zappers don’t work because flies seem to be attracted to smell not light and you cAnt really place the bait efficiently in them. I fixed the problem by buying zappers that charged from USB cables and had them connected to power directly.I do follow your advice and duct taped the switch on. It works like a charm although doesn’t look great aesthetically
I would've had to break away some of the plastic molded tabs on the inside of the handle to fit the extra capacitor, thanks for your comment, cheers...
Just over 3 minutes into your video. I really enjoy DIY, and am finding that I desire a closer camera shot. Maybe in future videos you can implement this.
Luc Peeters on this particular model the capacitor is across the secondary windings of the transformer, no resistor at all. I can press the button and come back to it after 30 mins or so an it will still spark. Thanks for you comment.
@@nikitaverginadis8579 sir , I need a way to modify EITHER , this type of zapper racket .. *OR* .. the big electrical - AC operated - one , to be operated continuously by DC 12V of solar system ... Is there any way to doing so , you - or any one else here knows - PLEASE explain it in a reply !!! ... thank you in advance .
Is there a reason they go from DC to AC and back to DC? Obviously batteries are DC and you want DC for final, but do they just not make a step up DC to DC to 3000V ?
Suijin Noname, I think it's a cost issue, both circuits would need a transformer, and this one is effective and cheaper to manufacture, with minimal parts...
The current (amps) at the AC end is very small, it would tickle a fly. Therefore its converted to DC and the capacitor is used to store the charge, thus supplying high voltage and a burst of high current enough to zap a fly.
DC doesn't increase voltage going thru a transformer, so you have to convert DC to AC using that oscillating transistor. The transformer hikes the voltage up and then the diodes convert back to DC to do the zapping.
@@PF-gi9vv Honestly original capacitor is not enough, it's only bruise fly's and they quickly return to flying, that's why i looked for increasing power to one tap them.
well done sir , useful info. ... I need a way to modify EITHER , this type of zapper racket .. OR .. the big electrical - AC operated - one , to be operated continuously by DC 12V of solar system ...

Can you tell me why just adding a capacitor ads more voltage? Isn’t the parallel going te have the same voltage on both capacitors namely the voltage coming out of the transformer? Please help!
voltage will be the same, charge time on cap increased , but also discharge current greater, cap needs to be high enough voltage rating not to break down
The original capacitor is usually 1.5/2kvolt, the one you have mounted is certainly lower if you have removed it from a grinder, with the voltages involved it risks exploding.
No, adding additional capacitance only increases the level of stored charge. It does nothing to change the voltage ⚡ input. To increase voltage you can do one of 3 things. Increase battery voltage to say a 9v battery. Modify the built in voltage doubler circuit into a tripler by adding additional capacitors and diodes to the circuit. Swap out the transformer for one with a higher turns ratio. OR..... you could just do away with the factory guts and make one of those 50,000v modules for sale on Amazon and eBay fit inside the handle along with adding the biggest 3.5-6v rechargeable lithium battery you can cram into it. Guaranteed devastation then!
If you do modify the circuit by increasing voltage ⚡, THEN you may have to install a capacitor with a higher voltage rating.... just remember that a capacitors voltage rating is only indicative of what it can withstand voltage wise. It says nothing about total capacitance and is not to be interpreted as an output value. A 10,000 v capacitor can work just as fine at 5 volts. Just don't exceed 10k on voltage.
What you that'd be a 22000 picofarad capacitor at 2000 volts, so 0.022 microfarad. Go with a 0.2 or so microfarad capacitor, so a 204, 224j (j is the tolerance of 10pF x5 +- the stated value and isn't critical at all in this application).
just fyi, you can simply attach 1 lead of the cap to the inside wire grid and 1 lead to the outside wire grid (both outside wire grids are electrically connected already), no need to disassemble as electrically the same place you placed yours. Be careful, wrong selection of cap and the cap can go boom... yes explode : )
Yes, you are right about the grids being electrically connected to the capacitor, but I found it near impossible to solder on the aluminium grid, hence taking apart the handle to solder on the capacitor leads. Thanks for your comment Kenneth...
How would that be of any use? It would have to be connected to a USB power supply to be used. It would just be annoying because now you have to carry around a USB power bank with it.
.22uf doesn't really seem like much. What are the voltage ratings on those capacitors? I'm thinking the extra capacitance wouldn't increase the voltage at all but it would increase the current during the discharge. Definitely be careful.
@@chich7089 are you sure it was 27 microfarads? That's awfully fully tiny for such a value and would likely bog down the oscillator due to inrush. Perhaps 0.22 uF, which would be more like that form factor?
@@chich7089 I'v been thinking about building a mouse trap with these zappers.But I don't want to kill myself.With the component you added if i added another one do you think that would kill a mouse?.So there would be 3compacitors all up.My email is flyingonetoe@hotmail.com thanks
Hello, looks like there was room right above the original capacitor inside the casing. i think it is saver to placer the extra capacitor inside. regards
Yes, I see what you mean, but the capacitor was just a little too big to fit in there probably. This capacitor was taken out of a broken grinder, I have since collected a few more that will actually fit in the space you mentioned, thanks for your comment 🙂
