Intro: Homemade High Voltage Pulse Transformer Video

I made this by winding lots of 40AWG wire around a 15mm PVC pipe and then covering it in electrical tape. I then used some 2.5mm2 house wiring as a primary coil and pulsed 1.2kV DC using one of those hand-held bug zappers through a spark gap and a timing capacitor of 0.047uF and the result is a high voltage spark on the output.

A good spark you can produce it, but I have a question for you, How many turns the secundary has? Thanks.

Hi, I'm not sure of the exact number but it was a single layer of 40 AWG enamelled coated wire wound on a 15mm diameter 10cm long piece of PVC pipe with a piece of ferrite rod inserted into the pipe as a core. Electrical tape was then wound over it and the primary was a couple turns of thick wire.

Short answer: As many as possible but keep it to one layer thick or else it will arc over.

sorry i did not see the ferrite core i am highly intrested in this project

The core must be ferrous, which it is. When it is used as a core it magnetises and de-magnetises each time there is current going through the primary coil.

Basically it switches between being magnetic and non-magnetic.

Here are some more photos of it being made https://www.instructables.com/id/Homemade-high-voltage-transformer/

Thanks. I am going to add some more photos at some point and a better explanation.
