DIY plasma ball

The role of our plasma ball will be an ordinary incandescent lamp, but the high-voltage source of high frequency is quite simple. In addition, from our source it is possible to build not only a plasma ball, but also to demonstrate beautiful experiments with high voltage: arc and corona discharges, Jacob's staircase, a fluorescent lamp that lights up in your hand, etc.

Electrically current is not a toy! Before starting work, I highly recommend that you familiarize yourself with the safety precautions in the article about Jacob's ladder.

Short description

The main element is the fuel assembly (Transformer Output String). Thanks to the original self-generating circuit, it was possible to obtain a voltage of about 90 kV, high power, reliability and efficiency. The generator circuit on the line - the blocking generator - is given below:

In this circuit, a converted transformer from a TVS-110L6 or TVS-110LA tube TV is used. The primary winding is removed and replaced with a home-made one, with a small number of turns. The rectifying unit is 12 volts and current up to 5 amperes. The turns of the fuel assembly are somewhere 1-2 = 5 turns, 3-4 = 25 turns of wire with a diameter of 1mm. In general, everything is selected experimentally. A transistor is more powerful like CT 927 or any other with a good gain and power.

The assembled circuit may look like this:

Or so:

On the basis of this converter, you can conduct your first experiments in the field of high voltage. These are Jacob’s small stairs, an ion engine, ozone production, electric ignition, ignition of an arc that can easily burn glass, and much more.

Our task is to build a plasma ball. To do this, we take an incandescent lamp and connect the transformer output to it.

A discharge in an incandescent lamp, the first electrode is a finger, the second is a spiral inside. Inside the flask is not vacuum, but argon gas, under low pressure:

BE CAREFUL ! HIGH VOLTAGE DANGEROUS FOR LIFE !!!!

GOOD LUCK TO YOU !
