Build your Tesla Coil Generator | Nikola Tesla: Nikola Tesla is the first person who created a way to supply power without wires. Tesla coil -categorically Nikola Tesla’s most famous invention is the first system that can transmit electricity without wires.
Debunking the awe around Tesla coils, it’s simply a high-voltage resonance transformer working in the absence a core.

History of Tesla Coil

Back in his days, Nikola was an inventor and genius disputing Marconi and Edison. He just wasn’t as business savvy or stern. Earning a reputation in popular culture as a quintessential “mad scientist”, it is depressing to consider that the standard unit of magnetic flux density is named after someone who died impoverished and in obscurity .
Tesla coil was developed in 1891 before conventional iron-core transformers were used to manufacture telephone circuits. Conventional transformers are unable to withstand the high voltage and high frequency that the looser coils in Tesla’s invention can tolerate.

So,what exactly is Tesla coil?

In a layman’s language,simply a high-frequency air-core transformer. Tesla coils are capable of creating extremely powerful electrical fields. Coils the dimension of Tesla’s coil have been able to wirelessly light up florescent lights even as far as 17 yards away, and because it employs the use of the electric field that goes directly into the light and doesn’t bestow the use the electrodes, even burned-out fluorescent lights glow.
The coil takes the output from a 120vAC to several KV transformer & driver circuit and finally steps it up to an extremely high voltage. Voltages are discharged in the form of electrical arcs and sometimes can get above 1,000,000 volts. Tesla himself got arcs up to 100,000,000 volts, and it’s not been tantamounted by anyone else since.

Construction of Tesla Coil

The working principle the coil makes use of electromagnetic force and resonance. Employing basic household equipment like copper wire,it’s fairly easy for anyone to build a Tesla coil that can produce up to a quarter of a million volts.
Here’s how even a novice can make a paradigmatic model of tesla coil:

Materials required :

tesla-coil

  • A power supply, 9-21V (simple batteries with same voltage would also do) .
  • A heatsink
  • A variable 50 Kohm resistor
  • An 180 Ohm resistor
  • Copper winding wire 0.1-0.3mm, 200 meters.
  • Transistor 13009 or 13007(any NPN transistors with similar parameters would also do)
  • A frame for secondary coil could be any dielectric cylinder diameter of 5cm and length of 20cm. Here we are using a piece of 1-1/2 inch PVC pipe.

Step 1: Circuit
Set up the circuit as shown in the diagram.

Step 2: Coils
Primary coil can be made by winding 10 turns of regular wire in PVC isolation.
Secondary coil has 500-1500 turns turn to turn. Wind the coil on a cardboard roll and then fix with wire with some tape.

Step 3: Soldering
Connect primary and secondary coils, latter has a special insulation which must be scraped off before soldering.

Step 4:Turn on
Almost done.

Before turning on the power for the first time, the variable resistor is placed in middle position and the light bulb is put near to the coil. It is not possible to see high voltage sparks immediately and only thing evident would be glowing light bulb. After turning on the power, slowly turn the variable resistor. It should be heedful not to place any electronic devices near to the working coil. If Tesla coil doesn’t work flipping the primary coil would resolve the issue, also you can try to add or subtract a couple of turns from it.

Step 5: Finally
Yay! The bulb glows.

For further improvising results, we can rise voltage, but it is not advised to go over 25V at this basic circuit.
Since logic is simple-fewer turns-more current-more power and more hitting,so fiddling around with primary and secondary coil will give wide-ranging results.
