Electrical How Did I Safely Build and Use a Tesla Coil for Entertainment and Education?

AI Thread Summary
A Tesla coil, invented by Nikola Tesla in 1891, generates high-voltage, low-current electricity for entertainment and educational purposes. The construction involves a circuit with a MJE 13007 transistor, allowing rapid current modulation to produce high voltage in the secondary coil. The design uses a 1.5 mm diameter wire with five turns for the primary coil and a 0.3 mm wire with 830 turns for the secondary. While the experiment is generally safe, caution is advised as the high voltage can cause skin burns upon contact. Overall, building a Tesla coil serves as an engaging way to learn about electronics and resonant transformer circuits.

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).
 
Some time ago I posted this Raspberry PI DIY Mass Spec using Raman Scattering. It's was something of a cumbersome project though, needing a 3D printer and special heat-resistant plastic giving of carcinogenic fumes during printing. To be blunt it was also not very mobile and interpreting the results was further cumbersome Recently though, I've been told that Arduino, and it's various sensor packages, has matured to the point where it's a usable alternative. Now I realize that a cigarette...
