I'm attempting to build a high voltage generator based on a tutorial I found online. I used a 0.1mm x 50m copper wire and wound it around a paper cylinder with a diameter of 0.4 cm more than 1600 times. After completing the transformer, I realized it needed a metal core, so I made one with paperclips as shown in the video. Unfortunately, it still didn't work, and my voltmeter is showing 0 volts on the output. Does anyone have any ideas on what could be wrong? By the way, I apologize for my English as it's not my first language.

Yeah, the ferrite core is key for your transformer to work properly, especially for high frequencies. The separations in the coil prevent the windings from touching each other, which helps maintain a strong magnetic field and improves the overall efficiency. If the turns are too close together, it could cause all sorts of issues. So make sure to keep those in mind next time!
It sounds like you might have missed some critical steps in the tutorial. The transformer needs the proper ferrite core and the coil should have separations to function as intended. If you’re not using the right parts, it may not work at all. I suggest looking into getting the appropriate materials or consider purchasing a ready-made high voltage module instead. Also, don’t try measuring the output with a multimeter; it’s risky! Use a neon indicator bulb instead—it’ll light up when you generate around a hundred volts, which means your circuit is at least oscillating.
Thanks for the tip! I’ll definitely try the neon bulb—sounds safer!
Could you explain why the separations in the coil are important? I read something about it, but I'm not entirely sure.
I appreciate the clarification! I’ll look into adjusting my design accordingly.
