You need higher frequency AC input (as mentioned) with perhaps a smooth positive terminal like a brass sphere or a tubular copper ring. This will reduce the high electric fields at the conductors, allowing the voltage to build up much higher before arcing.

I saw that HV diode come with ring connector, so... if he solder between capacitor and diode through that ring connector, will it reduce the high electric field at the conductor of each stage better than a ring connector at the input?

A gieger detector kit I bought had a tiny step-up transformer and will only work a tiny low loss diode. I tried lots of other special HV diodes. I buy MKP HV caps used in IH cooktops, cheap and tough.

Correct me if I am wrong. Or if someone else commented about the same thing, but what I have heard and seen, the Cockcroft-Walton generator actually does work with DC also. But it has to be pulsed DC what i have understood.

Love all your videos!

Spray it with transparent lacquer for better insulation , 6-8 layers I recommend

Simple experiment. Nice job.

Yes please show a working one, also maybe highlight the trace of the electricity flow? Thank you. Subbed.

You do cool work, by the way!

Hola Manuel, cómo estás? buen tuto y gracias por compartirlo. ¿Qué pasó con tu otro canal de youtube? Ahora tus tutos, serán solamente en inglés?

Could you please make an experiment with an electrostatic field?

Can you make high voltage caps for 50kv ?(100nF)

it would work much better under oil and would provide much more current using high frequency input from your mazilli/ZVS driver. Other than that, its a pretty cool multiplier!

voltage multipliers like this are known for leaking but also there is a point of diminishing returns with this method and at some point adding more stages is pointless. in any case i made one that i put inside of a PVC pipe, which i then filled up with candle wax for insulation. that made a big difference in performance.

Where do you get high voltage components? I was checking on HVstuff and read some comments in some forums about being a scam.

Does the input have to be a sine wave? Or can a square wave work?

Dear Mr Ludic: Nice video! 😀 I also noticed that you say "JLCPCB" now, not "GLCPCB" anymore! 😀 👍 I was wondering, can I use the transformer out of an old microwave oven to make a nice arc generator or Jacob's Ladder?

You could, but I wouldn´t recommend it. It is extremely dangerous for many reasons.

Caps maybe fine, film caps have a fast discharge rate (nanoseconds) so give up the charge quickly the culprits may be the slow recovery diodes at such low input frequencies also , i use faster high voltage diodes not microwave diodes (very slow recovery) and higher input frequencies (khz) with the same capacitors and get well over 100kv from the same setup (well corona doped or potted in parafine wax or epoxy) and the discharges are awesome! thanks for a nice video on my favourite topic though your content is always great.....

@@moki2093 I do indeed know about "skin effect" You are correct in identifying the difference between how 50hz really hurts and 500khz doesn't register to our senses. This is AC resistance based, not DC resistance based. Also in this case the output to ground is capacitive discharge. DC. The frequency input is separate. The skin effect has no place in a DC discharge I can assure you it hurts 100x more at high frequency.

It depends on the current path. If you touch with one hand, you will get a very nasty shock and maybe burnt skin. But if you touch one pole with one hand and the other pole with the other hand, the current passes through your chest, on the heart circuit and you can die.

You've must have meant 20 kHz? 20Hz stops your heart more certain than 50Hz. Higher frequencies, those which are kHz or tens of kHz wont likely stop your heart anymore but you'd might get burns on your skin, depends tho. With Power low enough it would just tickle.
