PLASMA RAY GUN (20000 VOLTS)

HELLO AND WELCOME BACK !!!!

Understanding and playing with plasma arcs ( the 4th state of matter ) is quite interesting but do we have a complete knowledge about it or can we build one on our own !!!!

AS being a fan of plasma arcs I thought why not to create a high voltage plasma power source that could spit out plasma arcs . Plasma arcs are fascinating to look at and can sooth you for a while ! It has a lot of applications and plasma physics is a vast field of study .

So This build is gonna be mind blowing

LET'S GET STARTED !!!!!

* FLYBACK TRANSFORMER (OLD CRT TV'S OR TIG MACHINES)

* A RAY GUN KIND OF THING

* 10 - 15 VOLTAGE POWER SOURCE

* T0 220 HEAT SINK

* SOLID CORE WIRES

* IRF Z44 N N CHANNEL MOSFET OR SOME POWER MOSFETS

* 150 OHM RESISTORS

WATCH THE VIDEO FOR BETTER UNDERSTANDING THE PLASMA POWER SOURCE AS WELL AS THE CIRCUIT !!!

Flyback transformers are one of the most widely use high voltage source . SO where can you get it You ask ?? You can find it in OLD CRT TV'S or maybe you can buy it online .

NOTE ON FLYBACKS : Flyback transformer is the a ferrite core transformer with few primary windings and a lot of secondary windings . After supplying a voltage of around 10 volts you will get and output of around 18000 - 20000 volts . There are a lot of videos about flybacks . But one quick note if you are not able to determine the primary windings as they are difficult to find So instead wind 2 turns then center tap the other 2 turns .

The most crucial thing here is a flyback transformer , as you can se i have just burned the primary windings and now have to make my own primary with some thick coated red copper wire !!!!

We need a mosfet as a fast switching device with low rds(on). and a huge heat sink , 150 ohm gate driving resistor . a prototyping board and a ray gun kind of thing salvaged from some old pcb .

SCHEMATIC is quite easy to understand ,

FIrstly we supply 12 to 15 volts at the screw terminals , The supplied voltage turns the gate on through the winding and as soon as the gate turns on the drain to source path become active and induces a voltage in secondary and after a while the saturation of ferrite core turns the gate off through a feedback winding

THIS switching madness goes on and on

Switching frequency is around 15 khz and thats where the audible frequency lies .

Firstly I started with fixing the ray gun kind of thing and a screw terminal around 5 cm apart and then added the flyback transformer gate driving resistor of 150 ohm and a mosfet with a huge heat sink and lastly added screw terminals for supply .

And basically we are done !!!!

XENON ARGON NEON AND KRYPTON ARE INERT GASES THAT GLOW IN PRESENCE OF HIGH VOLTAGE !!!
