Mosquito disintegrator

[ivconic]

Anyone who knows me a little better; knows how much I truly hate mosquitoes... from the bottom of my soul!
30.. and more years ago, I brought from Greece two UV lamps that kill mosquitoes. A mosquito literally explodes when it touches the metal mesh.
Then there was real technique and real quality of those devices, as well as everything else.
Those two lamps have disappeared in time...
In recent years, everything that can be bought in stores is mostly 101% "Made in China". I don't have a problem with that, but those lamps are really not efficient.
In the best case, the mosquito will "stick" to the mesh and die over time... from boredom...!
A few years ago, I "dreamed" of those lamps from Greece, which burned mosquitoes noisily and with a big bang, a pleasure for the ears and the eyes, and especially for the soul!
The other day, I found a video intercom in the scrap yard, a small CRT screen, it has a high-voltage part like any TV.
I take out that part, install it in some nonsensical box, glue the mesh with epoxy, insert the led strip into the mesh, activate only
the blue color (I guess that color attracts them the most?)
But I know from past experience that the high voltage part gets hot and will burn out very quickly if it keeps sparking to ground.
And the spark is big, 5-6 cm at least.
That's why I added high resistances on both sides. All in all about 100M... maybe a little more. It worked without a mesh so there was no spark.
The resistance has done its job. But when I mounted the mesh; as if the grid itself "amplifies" the voltage and neutralizes the added resistance???
Today I installed it in front of the terrace, but it's loud, there are sparks everywhere... I'm afraid that this "noise" will drive away mosquitoes and not
attract them (admittedly, the effect is positive even if it drives them away, but I want to enjoy while watching them explode)...
Not sure how to neutralize this effect? Should I add more resistance?

Under the terrace on the left I have a pond with trout. At night, when it is dark, the trout jump out and hunt mosquitoes and other flying insects.
You can hear the splashing in the pool all night long. Trout are the ultimate predators. I enjoy listening to them in action!
But unfortunately there are so many mosquitoes that even the trout can't do the job.
The presence of the pool and moisture... mosquito breeding grounds around the pool, in the grass, in tree branches, in flowers...
I've heard that lavender gives off a scent that repels mosquitoes. But who to plants lavender on the terrace now!
I'll have to work harder on that disintegrator!

How cool is this in the dark!


With all that; also produces ozone! Of course, ozone is very good in small amounts but very harmful in larger amounts.
That's why the "disintegrator" is outside the room, on the terrace, in the draft.
Only a small fraction of ozone will enter the room.

You do come up with interesting projects.

Adding series resistance reduces the Current but not the Voltage.
It is the Voltage that arcs. Reduce the Voltage and the arcing will reduce.

Actually quite correct points! What was I thinking?
I added resistances to prevent flyback output to warm, get hot and eventually burn.
But you are right; it is the voltage and not the current, to adjust.
It is small pcb with conventional CRT stages. I will have to inspect and see how to reduce the voltage.
Eh... if I could wake up Nikola Tesla and ask him!

And when I think about it, you are 101% right!
With these resistors, I totally "killed" the current!
I watched last night through the window what was happening.
A mosquito flies in and "sticks" to the net. But there is no spark.
It doesn't explode.
I go outside and use a toothpick to unhook him from the net... and he flies away!!!
I need to reduce the voltage so that there are not so many sparks and I need to increase the current (remove some of the resistors)
so that the mosquitoes explode... to my great delight!

lol

There may be a way to reduce Voltage within the flyback circuit.
If not then a resistor divider can do it.

In the meantime, the device killed many mosquitoes, so I decided not to touch it.
It seems to have variable behavior, depending on the humidity in the air, which is logical.
Extremely high voltages are a separate topic in themselves, a whole part of science. I have to admit that I didn't fully read that part.
Once upon a time, I used to repair TVs and had several "meetings with reality and my ancestors" when such voltage would give me a good shake... courage has its price!
But I still understood and remembered some rough basics.
For now, everything is ok, the device is still working, no problems. Let it stay that way.
