Tesla Coil

Tesla invented by Nikola Tesla has a long history:

A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage, low current, frequency alternating current electricity-high. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.

Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, generation X-ray, high frequency alternating current phenomena, electrotherapy, and transmission of electricity without wires. Tesla coil circuits are used commercially sparkgap radio transmitters for wireless telegraphy until 1920 and medical equipment etc.

The original Tesla coil transformer employed a capacitor which, upon break-down of a short spark gap, became connected to a coil of a few turns (the primary winding set), forming a resonant circuit with the frequency of oscillation, usually 20–100 kHz, determined by the capacitance of the capacitor and the inductance of the coil. The capacitor was charged to the voltage necessary to rupture the air of the gap during the input line cycle, about 10 kV by a line-powered transformer connected across the gap. The line transformer was designed to have higher than normal leakage inductance to tolerate the short circuit occurring while the gap remained ionized, or for the few milliseconds until the high frequency current had died away.

To make this speaker, the things you will need are:

Transistor 2n2222

2. Resistor 22K

3. Switch

4. Led 3v

5. Bread Board, Pcb and some wire

I've already made a tesla not difficult but with a large voltage to 9v not, that I first tested in bread board since the work made in the pcb and came up with a good result to trigger an economic light.
