Teardown & Hack Electric Flyswatter

Tearing down an electric flyswatter from a $2 shop then adding another capacitor to make the spark much larger.

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.

[@chrisbusenkell]

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?

[@chich7089]

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!!!

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.

[@thaynecearrachkerr8497]

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.

[@chich7089]

Nice idea 👍, I think it'll work if you put a UV globe in the centre just like the traditional bug zappers you plug into the mains...

[@SabriHaimid]

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

Its an awesome hack! Thx. Is it possible to make the circuit at home and make our own customize Electric flyswatter?

[@the_effect_de]

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.

[@FknNefFy]

I think it’s so funny how you can find videos on KZbin 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

I saw mine has a 0.33uF 275V one in it and a small resistor. Could I use a 180uF 400V one or is that too much Farad for safety?

[@chich7089]

It will take too long to "charge up", I have tried this before and it took a while between useful "zaps"

[@Shishou_Shi]

@@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.

[@user-2uf2kr2c]

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

[@chich7089]

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 🙂

Yes, the 2 yellow wires are the outer grid, the red inside one is the positive.

[@kiplandingham322]

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.

[@serhio4275]

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.

[@ToreTangKanalen]

Would it make any difference just changing the battery pack to a 9V?

[@PF-gi9vv]

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.

[@dangood6949]

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.

[@saviolicious5]

@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

Whats the rating on the cap?

[@Mr._Lister_The_Sister_Phister]

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".

[@delaIII]

can you use a h v capacitor to up voltage

[@ripstephenhawking8787]

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!

[@ripstephenhawking8787]

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.

Thanks Sean, taken on board...

[@gouwehandjes]

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.

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 : )
