What phenomena can be demonstrated by a cheap high voltage generator?
« on: 27/03/2023 16:39:27 »
I've got one of it, and recorded some videos with it. It can generate spark 1 to 2 cm long in open air. Some dielectric barrier can prevent the formation of spark. I think there are many interesting things can be shown with it.

I do not know anything about HVG.

But, why is it called Generator?

Does it Generate, which i feel is similar to Create?

Or does it simply just Convert, hence a Converter/Transformer?

(by the way, Good Job putting up those WARNING Signs at the beginning)

Perhaps for marketing purpose. That's the title of the device if you buy it online.

The circuit diagram shown at 6:50 shows that it consists of an oscillator, step up transformer, and voltage multiplier.

https://en.wikipedia.org/wiki/Voltage_multiplier

Even "real" generators merely produce electricity by converting from other forms of energy.

By analogy with things like this
https://en.wikipedia.org/wiki/Van_de_Graaff_generator
All but the very smallest are driven by electric motors.

Some online shops market this device as "Tesla coil module", but the video above shows that it's not.
To make sure, I've measured the output of the module using a multimeter. In resistance mode, the meter shows over-range value, and can't distinguish it from an open circuit. But in capacitance mode, there is a small value shown by the meter. These results are more consistent with the output of a voltage multiplier, rather than a Tesla coil.

The output of a voltage multiplier produces DC, while Tesla coil produces AC voltage. But my experiments done with it so far haven't shown noticeable difference. Other than producing spark, I've also used the device to lit up a UVC light tube which I've used in my other experiment on microwave transceiver.

Can it be used to create a Taser?
& If Yes, can it be disguised as a Lipstick?

Some online shops advertised this device as a taser. Although it may not meet the criteria.

I've been inadvertently shocked several times during my experiments, although not at its full power. The small capacitance of capacitors in the voltage multiplier part, as well as small transistor in oscillator part limit the power delivered to human bodybody,  and may not be capable of paralyzing an adult.

Hmm...so it could make an Attacking stray cat or dog run away, but won't work on Humans.

Best not to weaponize it.
If You did, then You will make video & upload, then Cops will come to your house & then You might fall into Trouble!

By the way, You broke & tore it apart in the Video.
But still it might be Worth something Right?
Like, it's got precious metals inside.
Any Resale Value?

(Plz be more cautious & careful next time, wear some rubber gloves or something Yes)

It wasn't me. I posted it as an introduction to what I will use in my experiments.
My device is still working fine, at least for now.

Sorry, i missed the Details in the Video.
& Sorry for the Bad Suggestion of making a Tazer out of it.

Well how about making a Car Jump Starter from it.

When cars don't start, bcoz of dead battery.
Then another car or live battery is required to start the dead battery car.

If a battery pack is attached to this HVG, n two small wires...Can a Jump Starter Keychain be made from this?

Jump starting gasoline cars is usually needed because of dead battery. It requires good condition of other components. It also requires high power. Normally, the engine is started using 12V car battery, and can draw current to hundreds of Amperes typically 400A, hence 4.8 kW is required. When the power is too low, it would be cooled down by the fuel and fail to ignite.

I've made several experiments with the device using a 10Ah USB power bank as the power supply. But it seemed that The power bank got depleted faster each time, until finally it can only produce a single spark before it stopped working. It cannot be recharged anymore.

I replaced the power bank with a new one, but the same thing happened. Now I have two dead power banks. I guess there's something wrong with the electronic components in the high voltage generator.

I'm curious if the electronic device can produce observable electrostatic effects as shown in the videos below using Van de Graaff generator.

Fun with Static Electricity! - A Prequel to "Should a Person Touch 200,000 Volts?"

Should a Person Touch 200,000 Volts? A Van de Graaff generator experiment!

The spark produced by the Van de Graaff generator looks longer than my device's. Something must be off. It's either the video author underestimated his generator, or my generator has actually lower voltage than advertised.

Looks like you Finally made something, a Power Bank Killer!

Anyways, aren't the Power Banks repairable?

Was it the whole chemical Battery component that was Severely damaged, or just the internal circuitry Chips?

I haven't checked them yet. My plan for the next step is to use a USB adaptor instead of power bank.

Well!
As long as You aren't messing or interfering or experimenting Directly with the electrical wall sockets of your Home, it'll be Fine!

But if tomorrow, all of a sudden, the whole Planet loses Electricity n is plunged into Darkness...

OK. Finally I finished editing the videos and uploaded them to my Youtube channel.
The first video is an introduction of the high voltage generator device used in my experiments.
