How to Build a Tesla Generator – HomeMade Tesla Coil

What is Tesla coil?

Nikola tesla phobia.tech

Tesla coil is a device that can transfer energy through space. It can transfer energy within a small distance. But the distance can be varied with the Tesla coil power. This is a similar theory which is using in the transformers. (tags: how to build a tesla generator)

Tesla coil was invented by Nicola Tesla. There are two coils in the Tesla coil (Primary coil and Secondary coil). When we supply the Low voltage and hi-frequency to the Secondary coil, the Primary coil will generate the hi voltage. Also, that voltage will create a capacitor between the top end and the bottom end of the Primary coil.

What do we need?

  • magnetic Copper wire for Primary coil (recommend to use 28 gauge copper wire).
    • But I use a Toy motor to get copper wire. 🙂

  • magnetic Copper wire for Secondary coil (recommend to use 22 gauge copper wire).
    • But I use a house wiring wire to get copper wire. 🙂

  • PVC Pipe
    • Recommend to use 2cm Diameter and 9cm Length pipe

  • Transistor
    • 2N2222A

  • Resistor
    • 22K Ohm
    • Color code: RED, RED, ORANGE, GOLD

  • Battery (9V)
  • Cardboard
    • I used a piece of wood.

Let’s make a simple stand for the Tesla coil

(Use your own method to make it.)

  • I found this piece of wood, but you can also use Cardboard Sheet.

  • Also I found this items, inside the lamp holder. I used it to attach wires and coil to the wood plate.

  • Also, i brought this jumper wires from eBay.

  • Now attach the wires to the plate

Now we make the secondary coil

Create the coil like this from the wire that we get from the house wiring wire.

Tesla secondary coil

Now we can complete the stand

  • Connect the secondary coil to the stand.

Now we make the primary coil

  • Get the magnetic coil, that we got from the toy motor

  • And the PVC pipe

  • Then winde the coil 300-400 turns to the Pipe.

Now we attach the primary coil to the stand.

  • Glue the Primary coil to the stand, and take the bottom coil end to the other side of the stand through the hale.

  • Now get the wire and connect it with bottom end of the coil.
    • Before connect the wire, burn the end of the coil.

Now we can create the Circuit

Now create the circuit using this circuit diagram. In my case, I create a temporary circuit using the Breadboard. this is not necessary, you can use PCB or Vero board directly.

Now make sure the circuit is working.

It’s working…

Okay, now we can go with the Vero board. This is the Vero board that I buy from eBay.

And i cut the piece of the board.

Now connect the components to the vero board and solder it.

Complete the Tesla coil (How to build a tesla generator)

Connect the Primary and Secondary coils to the circuit.

Now complete the setup. 🙂
