SUMMARY

The discussion focuses on the construction and safe use of a Tesla coil, an electrical resonant transformer circuit invented by Nikola Tesla in 1891. The user successfully built a Tesla coil utilizing an MJE 13007 transistor to rapidly switch current, resulting in high-voltage, low-current electricity for educational and entertainment purposes. The primary coil consists of 5 turns of 1.5 mm diameter wire, while the secondary coil has 830 turns of 0.3 mm wire. The experiment is deemed safe, with low current levels that can cause minor skin burns upon contact with the antenna.

PREREQUISITES
  • Understanding of electrical circuits and components

A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current high frequency alternating-current electricity.

Tesla tried to transfer energy with a wireless way. It was really difficult to do this to a long distance and as you had to increase the current for this , the experiment was dangerous . So the project stopped.

Today, their main use is for entertainment and educational displays.
In my Tesla coil I used a circuit with a MJE 13007 transistor that cuts and connects the current to the primary coil very quickly and produces a high voltage current with big frequency to the secondary coil. This is the reason that makes the ionization of the gas to this kind of bulbs.
I used a 1.5 mm diameter wire with 5 turns to the primary coil and a 0.3 mm with 830 turns to the secondary.

The experiment is not dangerous. The current is very low in the secondary and this kind of current ( very big voltage –very big frequency – very low current) passes through the surface of the skin.You can smell the skin that burns if you touch the antenna for 3-4 second or more. Nothing else. If you want to see bigger spark you must use more powerful power supply. About 30-40 volts and more than 100 w. YOU CAN WATCH THE CONSTRUCTION AND THE USE HERE:

Pretty cool. So, I assume you are just doing this to learn about practical construction of semi-exotic electronics items, yes? I mean, there isn't actually any practical application (not that there needs to be ... look like a great learning experience).
