I so fucking hate mosquitoes. At this point I'm seriously willing to lure all those bitches in and guide them straight to an electrical death. Problem is, I know how to generate super high voltage to char the fuckers right into smelly dust, but I don't know how to lure them in, or even find them manually, so let alone automatically. Even a chemical reaction we can electronically dispense to lure in the fuckers, but I have no idea what that chemical stuff would be. I'm not a chemist (yet). But if I can build it, fucking hell.. I would build a ton of them, weaponize my entire home and even build some spares to send off to fellow ranters. Because those parasitic bitches must DIE!! The only reason why they still exist after thousands of years is because we didn't kill the fuckers yet. I want to fucking kill the leeches, preferably in the most gruesome way possible.

So yeah. A shout for help to my fellow ranters this is.. perhaps even a collab. I have no idea about the stuff that draws those fuckers into their death. Any suggestions? Whoever can guide me to the demise of those parasitic pieces of shit, seriously.. if at all feasible, I'll build it for you and ship it!! Death to those parasitic blood-sucking bitches!!!

    This fucker is a blessing. We didn't use it for 2 or 3 days when we arrived here, my feets and legs look like verdun now...

    @Wack hmm, looks to be a light of some sort (UV? I've heard that that's quite good at luring in mosquitoes) with some sort of high voltage rail surrounding it... Come to think of it, those are sold as consumer electronics. Perhaps I'll buy one of those then and see how exactly it works 🙂 thanks for the suggestion!

    Maybe get some indoor mozzi repellent plants

    i made this exact thing in highschool. my physics project is done, and i don't want to waste that tesla coil, so i remove the IGBT driver and change it to chain of voltage multiplier and feed them with high frquencies.

    i use 3 net from the black lamp to outer layer it's negative voltage net, positive voltage net and then the protective layer net so i dont accidentally touch it. both + and - net was about 3 centimeters apart. and then spark would randomly jumping around so i found 4.5 ish is just enough if something electrically conductive passing both of the net it would vaporizes them instantly.

    the thing that i love is that the zap is loud enough to give me satisfying feel of killing those bastards, and 5 seconds later their vapor and smells came to my nose. mmmmhhh take that!

    @wowotek sounds like an interesting circuit! So essentially an AC voltage multiplier that's feeding 2 meshes (live as inner and neutral as outer mesh I presume?) and the lure inside is a black lamp..? What exactly is that? I've never heard of this yet. Also how many multiplication stages did you use?
  • 2
    @Condor i don't exactly know how it work actually, i always assume that tesla coil is basically a tranformer. as far is i remember the primary coil is feed using the high frequency voltage multiplier, the air gap is connected to the net. and then the secondary coil is just hanging inside the primary coil without any reason, it doesnt create arc but it does blink fluorescence lamp beside it

    @Condor oh and the volt. mult is (if i count the capacitor) 23 positive side and 13 negative side or vice versa since i can't exactly remember which side

    @wowotek thanks for the explanation 🙂 sounds like several kV then, given that it's a dozen or two multiplication stages. On the 3cm gap it didn't arc, right? Regarding voltage multipliers, I don't have much experience with it other than having seen ElectroBOOM's recent video about it. Apparently the caps introduce their own load so they can't be indefinitely added as extra stages. And there's a lot of leakage paths at high voltage too.. guess I'll have to take that into account. Probably I'll build mine using the circuit of that high voltage sparker that I've made earlier, that should give me a 7kV arc in DC which I can space out to.. let's say, 8mm. The black light is most interesting though, as that'd essentially be the lure. I couldn't find anything about it online, as "black light" only returns crap about lights with black enclosures.. pretty sure that Android Pie will face a similar fate (Pie used to be - and still is - a custom navigation control), but Google enganeers being what they are.. what can I say. But I digress. Does this black light go by any other names?

    @Condor try "mosquito uv lure"
  • 1
    @Condor as far as i remember it goes up to about 25-35kV and every zap is really HUGE hell of a bang. very loud. i think the net surface area leak the charges much since both net are close maybe the charges leak even more. the black light is specific UV light in specific wavelength (i believe). the lamp designed to emit UV light specificaly to attract mosquitos. not all UV lamp are designed this way.

    something to be in mind designed this thing is inefficiencies. my circuit draw about ~2Amps at 42v. maybe making a big capacitor discharge circuit is more efficient than an Arc design but you must make the net much closer than Arc-er design

    is @electrineer know bout this ?

    @wowotek I'm no biologist

    dude... get some bats. They kill like 10k-20k mosquitos per night. You ain't gonna beat this with your electrical whatever :)

    @wowotek yeah, the unwanted flux created by the arc circuit is what I'm most worried about. @Root has a similar problem on her quest to kill mosquitoes, albeit without an electronics background. AC generates unwanted magnetic fields, which are a trouble to deal with. DC doesn't do this (as it can't induct). That's the main reason why I'd prefer a DC circuit. Components that can handle beyond 1kV are rare though, so transformers which emit AC are the easiest endpoint. But I'd prefer to refrain from using that.

    Be careful with indoor UV sources, that thing causes skin cancer

    I remember reading somewhere something about an automated system that could target them and shoot them with lasers. sounded amazing.

    Anything sweet. A bowl of orange juice or something like that sends most bugs mad. Either that or a bowl of blood? XD

    @Condor my dad have somekind high-end component that i use tho, for example those 30 piece of 25kv capacitor and diode is no where i can find on regular market. if you want a simple DC circuit you can simply play around to overvoltage Bug Zapper circuit tho. since it was designed to kill bugs.
  • 1
    @wowotek 25kV caps are easy to source, they're just more expensive than regular caps and their capacitance is very low. And the diodes.. yeah the most common ones are the 1N4007 rectifier diodes that can handle up to 1kV across them.. which should be suitable for the voltage multiplier. As long as the voltage across them is less than 1kV, it can have something like 20kV on one terminal and 20.5kV on the other no problem. Maybe your dad's diodes were different ones though. Any idea what their part number is? It should be printed on the diodes.
  • 0
    @Condor no, i don't know where that mighty device is. i believe it is hard to find in regular store. the diode and the capacitor are huge, it is as big as a plastic bottle. it is like what you seen in electricity substation
  • 1
    @wowotek well I never use regular stores for components 😛 I always buy those online. But caps and diodes as big as a plastic bottle? You don't need a huge component to be able to handle a couple of kV, you know 😅 even 1mm of plastic insulation can have a sufficient dielectric strength to withstand several kV. Hence why those 1N4007 diodes are so small. And caps in that voltage range.. they're just regular size ceramic caps, but their capacitance is only a couple of picofarads.

    @Condor ikr, i even assemble the volt mult without a solder, my dad told me it's better using bolt and nuts. while usually i handle simpler circuit like amps driver; big difference.
  • 1
    @wowotek what? Fuck no! Nuts and bolts provide ways for the charges to run away. Sharp objects and large surfaces for charges to run away into, you'd want to avoid those like the plague in high voltage stuff! Also mechanical connections are less reliable than the chemical connections from solder joints. Running your entire circuit like that, I don't want to sound like an ass but that's quite crappy to be honest 😕

    @Condor i know, my dad just won't listen. but it's long way back then. i play with arduino and ras pi nowadays 😂😂
