DIY TESLA SIMPLE COIL

Send

Nikola Tesla is truly a brilliant inventor of all time. He practically created the whole modern world. Without his inventions, we would not have known for a long time about the electric current of what we know now.
One of Tesla's bright and amazing inventions is his coil or transformer. Which perfectly demonstrates the transmission of energy from a distance.
To conduct experiments, to please and surprise friends, you can assemble a simple, but fully working prototype at home. This does not require a large number of scarce parts and a lot of time.

To make a Tesla Coil, you need:

Bank from CD disks.
A piece of polypropylene tube.
Switch.
Transistor 2n2222 (domestic type kt815, kt817, kt805, etc. can be used).
Resistor 20-60 kOhm.
Wires.
Wire 0.08-0.3 mm.
9V battery or other 6-15V source.

Instruments: a clerical knife, a gun with hot glue, an awl, scissors and maybe another tool that is in almost every house.

DIY Tesla Coil Making

First of all, we need to cut a piece of polypropylene tube with a length of about 12-20 centimeters. Any pipe diameter, take what is at hand.

Take a thin wire. We fix one end with electrical tape and begin to wind it tightly, turn to turn, until we close the entire tube, leaving 1 centimeter from the edge. As we wind, we fix the second end of the wire also with electrical tape. You can hot glue, but in this case you have to wait a bit.

We take the case from the disks and make three holes for the wire. See the photo.

We cut out the groove for the switch with which we will turn our Tesla coil on and off.

To look better, I painted the box with spray paint.

We insert the switch. Glue the coil wound on the tube with hot glue in the middle of the can.

Pass the lower end of the wire through the hole.

We take the wire thicker. We will make a power coil out of it.

Wrap around the tube with wire. We do not close, at a certain distance. Coil 4-5 turns.

We pass both ends of the resulting coil into the holes.
Next, we assemble the circuit:

I glued the transistor to the hot glue to the lid from the soda, which I previously glued to the hot glue as well. Yes, in general, all elements, including wires and a battery, are fixed with this glue.

Next, we make an electrode. We take a ball from ping-pong, golf or another small ball and wrap it with aluminum foil. Cut off the excess with scissors.

We clean the wire from the top of the tube and fasten it to the ball foil. And we put all this on hot glue and on a tube.

That's all. If the circuit is assembled correctly, everything should work without problems. If for some reason this did not happen, then try swapping the ends of the power coil.
