In this video I show you how to make a homemade mini tesla coil, easy to make, with few materials and some recycled
an experiment of home made electricity, for science fair, school projects and to understand and demonstrate the operation of one of the most striking inventions of the great Nikola Tesla.

Our prototype basically consists of a transistor that works like a switch that opens and closes many times per second to create a pulsing current, the primary and secondary coils behave like a transformer
and for a transformer to work, it needs that alternating or pulsating current. Our coils are responsible for raising the voltage, this high voltage that is generated can be transmitted wirelessly. Although this prototype is of low power it can excite the gas in fluorescent tubes and neon bulbs.

The Tesla coils of power have tensions of millions of volts, this is a small experiment with which small-scale effects are demonstrated but still has the
same principle of operation without any danger.

recommendations

- Test the circuit on a breadboard or connecting with cables without welding them before final assembly.
- If it does not work the first time (that is why it is recommended before testing on a protoboard or without soldering yet) reverse the connection of the primary coil.
- The turns of the secondary coil must be completely together, without leaving gaps and none mounted on top of another.
- It is normal for the transistor to warm up, for this reason it is not recommended to leave it on for a long time and turn it off for a few seconds until its temperature drops (that is why I chose to put the connector for the transistor in case it burns to be able to change it easily)
- When making the connection the transistor should be with the numbers facing us otherwise it would not work.
