We make the exterminator of mosquitoes and other insects

Most of the winter has passed and it's time to think about the upcoming warm season. In this article, we will look at how to make a device that attracts light and kills insects with current. The main part of the device is an electric clapper. Such crackers are sold as electric fly swatter and cost around 200-300 rubles. Although, having such a device in the past, I personally could not fly, to persuade a fly swatter to get on a metal mesh or to catch them with this thing myself)))) Night insects are another matter, if there is a source of ultraviolet light, they will all fly on him and get on the grid under voltage. By the way, such a device, in stores already costs from 1200 rubles.



So, for the manufacture of such a device will need the following

Tools and materials:
-Electrical fly swatter;
-3.7 V lithium-ion battery;
- TP4056 charging module;
- UV LED 5mm;
-Shrink tubes;
-Cardboard;
-Wire;
-Soldering accessories;
-Knife;
-Pencil;
-Glue gun;
-Screwdriver;

Step one: disassemble the fly swatter
We check the operability of the fly swatter by holding a screwdriver to it.



Unscrew the screws and disassemble the case.


Dismantle the board.


We increase the wires going from the grid.






Step Two: Case
The body of the device is made of thick cardboard. In one wall, a window is cut to the size of the fly swatter grid.







Paints box details in blue.


Glues the spark gap to the cardboard.




Step Three: electronics
Now you need to finalize the board. Solder the jumper to the switch and solder the LED.





Solder the wires to the battery, the second ends to the charging module.




Solder a couple of wires to the output of the charging module, the second ends to the input of the board.




Solder the LED.




Now you need to solder the wires from the spark gap to the board contacts (to those contacts from which they were soldered).


Step Four: Build
We fix all the electronics inside the case.





Removes the diffuser from the LED lamp and sticks it above the LED.



Secures the walls of the housing.





Sets the button.


Now it remains to charge the device.


And check out his work.

So. except you them and no one sees. maybe in you business?
Are you sure about that? Interesting logic, you make mistakes, but it's me!

Because, as a regular one, a separate button was turned on. Means need to solder differently

Solder jumper to switch and solder the LED
I just can’t explain to the sensible author of the article to understand the essence of the question asked!
Well, if you chew such nonsense ...
For starters, it would not hurt you to chew for yourself! smile

How much stupid, I certainly understand that you need to solder the LED in place of the previously soldered regular
Well, I say, "look at the pictures." Because, as a regular one, a separate button was turned on. So you need to solder differently. Well, if you chew such nonsense ...

And I write for sane people. And sane people are well aware that the LED needs to be soldered to the contacts of the board, so that it lights up when the device is turned on
How stupid it is, I certainly understand that it is necessary to solder the LED to the place of the previously soldered out regular one (making sure there is a current-limiting resistor there, figuring out the difference between the currents of the red and ultraviolet LEDs). And how much stupid, I just can’t explain to the sane author of the article get to the bottom Asked Question! By the way, what about the second part of my question? smile

Solder the LED
Where to? Or again:
And I write for sane people

I would like to see the result of the device and the extraction of insects from the sealed case smile
