Assembly and testing of musical Tesla coils

Probably, most of us like to experiment and I am confident that all of you know who Nikola Tesla. This is truly a great inventor, who in fact is the father of all modern energy operating on an alternating current. In this article I want to show the assembly and operation of so-called "Tesla coil", which in fact is a resonant transformer.

This product was purchased by me in the online store Aliekspress and it's in this form:

Moreover, having examined all the details immediately struck by the lack of thermal grease, and any fasteners for most coil wound secondary housing. It is also completely absent circuit assembly, but the benefit itself is so simple, and the board has the notation, so that during assembly it is not needed. But if you find it easier to perceive the information with the scheme, this is what I found:

We begin to build

So the details are unpacked and laid out. The first thing we need to solder resistors and diodes (diode are not labeled, but the length of the legs can be determined, which is shorter negative and longer - positive, the resistance value is determined from the color indication).

The next step of our solder capacitors at the same time respecting the polarity, where it is needed.

Then we take our transistors and pre-treating the junction thermopaste fasten them to the heatsinks.

Hereinafter referred to as solder them:

Now it is necessary to solder the power supply connectors and a stereo. Yes, she is also a must play (that's check). A coil using hot melt glue to the board and solder it to an end.

Important. Red posting serves as a primary winding and must be twisted together into a kind of coil, the coil direction should coincide with the direction of the secondary windings of our.

That's all it is our plant is assembled, it's time to try it.

Oddly enough it starts, that's certainly one diode on the segment declined to glow, but it does not matter.

By the way, great food come from my laptop, as the board stated that the unit operates from 15 to 24 volts.

First run also demonstrated that the native radiators insufficient because literally within 20 seconds of operation, they were very hot. Therefore, there is clearly need to put a more powerful radiator, well, or think about the active cooling in the form of a fan.

The result of verification work and the possibility of playing music is provided in the video. Since the installation of low-power, the sound is very quiet, but I think you know the tune.

So, here is a review of this product turned out online store. If the topic you will be interesting, then put his finger up, and I will start to assemble a much more powerful installations already improvised (which you can later repeat).

Thank you for your attention!
