Hello to all electronics lovers. Perhaps you dreamed of doing something grandiose, high-voltage and spectacular in the electronics section, in this article I will tell you how to make a high-voltage generator, based on a kit ordered from China. Such a generator can easily light a sheet of paper, as well as power a gas discharge lamp.
Before starting to read the article, I suggest watching a video about the assembly of this kit and a little testing with a piece of paper.
In order to assemble this high voltage generator, you will need:
* Soldering iron, flux, solder
* Battery or power supply
* Device for soldering "third hand"
* Kit
That's all you need to build such a high voltage generator.
Step one.
First you need to decide what the circuit will be assembled for, for this the seller on Aliexpress has both a photo of the finished device and its electrical circuit. It seems to me easier to collect from a photograph of a finished device, since the electrical circuit may not be clear to everyone, as they say, a matter of taste.
First of all, we clamp the transistor marked N50 into the third-hand soldering device.
By the way, the entire structure will be assembled by hinged installation, since a printed circuit board is not provided, most likely due to the small number of components. If necessary, you can spread the printed circuit board, but I think this is unnecessary. We need to solder the wires to the transistor, but before that we tin out its legs well, for the best effect we use flux.
Solder the negative power wire to the right leg of the transistor, that is, to the emitter.
Now we solder the diode to the left leg (base), there is an indication of the position on the diode, that is, we place a gray strip on the diode to the transistor leg itself and solder it.
We solder the resistor to the diode output, for compactness, you can shorten the conclusions of each component.
Step Two
It's time to solder the transformer, which is the "heart" of this homemade. There are four leads on the transformer, two of them are wound together.
The right terminal of the transformer is soldered to the middle leg (collector) of the transistor, the two outputs soldered together are connected to the power plus, and the leftmost terminal is to the terminal of the resistor that was previously soldered. The remaining two green wires are the very high voltage leads.
Step Three
So the kit is practically assembled, it remains to install the transistor for cooling from aluminum, do not forget to install a thermally conductive gasket between them, as well as solder the contacts to the high-voltage wires of the transformer and also connect the power wires, in this case the power can be from 3.7 volts to 7.2 volts.
It is worth noting that with a large input voltage, the radiator starts to warm up well, which ultimately can damage the transistor, so at high voltages I advise you to install a larger radiator or install a fan for cooling.
This completes the assembly of the kit kit, using this high-voltage generator, you can turn on the discharge lamp without 220 volts on hand, which looks quite impressive and unusual. Also, based on this set, you can make a stun gun that will easily light a piece of paper, which can be useful, for example, on a trip.
Thank you all for your attention, successful repetitions in the assembly and new interesting ideas.
