DIY plasma ball


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



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


High frequency high voltage source

Purpose

Demonstration of beautiful experiments with high voltage: arc and corona discharges, Jacob's ladder, fluorescent lamp that lights up in the hand, etc.

Short description 

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


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

The assembled diagram might look like this:


Or like this:


Based on this converter, you can conduct your first experiments in the field of high voltage. These include small Jacob's ladders, an ion engine, ozone production, electric ignition, ignition of an arc that can easily burn through 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 a vacuum, but argon gas, under low pressure:







BE CAREFUL ! HIGH VOLTAGE IS DANGEROUS TO LIFE!!!!

    Will another line reader (from a non-tube TV) work? lumped

    Will do. But some lines have built-in high-voltage rectification circuits. If they are not removed, the liner will become really life-threatening!

    It’s clear that there’s just one more problem: my lineman has 14 legs and there were no 1st and 13th legs. And also from the coil itself there is a separate wire coming out, or rather a spring, as I understand it, this is grounding. and in the TV workshop they even said that they don’t know how to connect the liner outside the TV

    A low-voltage winding with nagas is not needed! read carefully - we wind it ourselves! Well, a high-voltage one should have two outputs: one to the common wire, the second to the lamp.

    I understood all the deltas as in the article and then just find the winding. Thanks

    What kind of capacitor is needed?

    from 500 microfarads and above, voltage depending on the transformer. If the trans is 12 volts, then the cander is 15 volts or higher

    Thank you. I have one more question. What other transistors will fit there?

    Yes, any powerful low-frequency...

    What comes after T1 according to the scheme
