Homemade Capacitor 19nF / 10KV

[ipaqmaster]

1:10 WOW thats awesome XD

.. now touch it =P

[OrionXBlaze]

discharging so fast the camera can't keep up

[kmncztms]

I made 2 leyden jars connected paralell to each other a few weeks ago. If I charge it with fur and plastic tube and approach the 2 wires, it makes a half cm long arc.

And I made your kind of capacitor today. If I charge it, it makes a very small spark.

Is it normal? :S

[radumotisan]

@kmncztms Yes, it is normal, because the leyden jars are suitable for electrostatic charging, while the capacitor in my video requires high voltage DC supply and won't work with electrostatic potential difference. The high voltage supply can be like the one I've used in a video (you can build one using a 555 circuit and a rectified flyback from TV/monitor)

[steadfast1984]

cool video, but it drives me crazy when people make vids and dont talk. like what are you doing when you squeeze it?

[radumotisan]

@steadfast1984 nothing, I just squeeze it :) . By doing so the space occupied by the dielectric becomes narrower and the capacitance increases .

[coilsinamotor]

thats frakin awsome

[radumotisan]

@coilsinamotor yes, it has some great potential

[coilsinamotor]

@radumotisan mhm minituriz this and u have urself a taser ;) muahahah

[radumotisan]

@coilsinamotor hehe, yes that would hurt a lot

[coilsinamotor]

@radumotisan yah but hey self prtection :)

[11223marc]

c'est l'ideal pour une bobine tesla non?

[radumotisan]

@11223marc Oui, je utiliser 3 condensateurs comme ça dans ma bobine tesla.

[zsharmarahul57907888]

is any1 who knows in dielectri oil at what voltage n current heat begin to generate?

or the procedure to trace down these quantities of any fluid.

or the breakdown voltage of dielectric fluids?

[juniortore1]

try it in oil

[juniortore1]

nice

[ubuntupokemoninc]

put in series

not parelel

[The2010SnowDay]

If you controlled the spark gap, you could have a morse code transmitter

[prototype9000]

not bad

[Blodslav]

That power supply is frickin beautifull man, how much power does it put out?

Is it a single transistor or dual transistor?

[radumotisan]

@Blodslav thanks. I've added the power supply links in the video description.

[Blodslav]

Hmm thats pretty cool i havent tried the capacitor between the anode and the base... does that have any noticeable effect on efficiency? Or heat reduction?

[radumotisan]

@Blodslav Which one?

[Blodslav]

The second link first circuit diagram for the HV supply. there are two capacitors on the anode. The one thats connected to the base of the transistor and the 22ohm resistor.

[radumotisan]

@Blodslav it appears to be influencing the frequency it operates at. I've tried several values, to obtain be most power out of it.

It is not a crucial component.

[TenFoldDamage]

It would more properly be called a 19000 pF capacitor OR .019(micro)F. NanoFarads dont exist as capacitors, only in math

[radumotisan]

nano is just a multiplying factor like ato, pico, micro, mili, etc.

it can be used anywhere numeric values are involved.

You use it for simplicity, writing 19nF is easier then 19000pF.

Like when you drive you don't say 100000000milimeters, but you say the trip was 100kilometers.

thanks for watching

[TenFoldDamage]

I am aware of this but 19nF only really exists in math, you only normally will see capacitors rated in pF or (micro)F. So thats why it would be more proper.

[Blodslav]

Well actually ive got alot of capacitors labeled in nF. Even newer makes still label with nF. I think its to save proceedure costs by having the printer not print all those zeros. It probably adds up, because companies who make them make millions of them.... thats alot of ink.

[radumotisan]

@TenFoldDamage I've just shown the 19nF capacitor in the video. How can you say it only exists in math? :)

again, nF pF etc are just multipliers. The idea is to express the value as easily as possible, and that means reducing some of those many zero's with the proper prefix letter.

[TenFoldDamage]

Im not going to continue this arguement even though i am right, good day sir

[radumotisan]

@TenFoldDamage unfortunately you aren't. try searching google for " 22nF capacitor " , etc.

[nwfklan]

Make a vid of how you made it!

Would be awesome :D

[radumotisan]

will try to do that. it is so simple: just some wide tape and aluminum foil! and the wires.

[EnlightenedPerson]

Dont freakin touch it. Damn.

[radumotisan]

I guess was lucky but also careful until now.

[lapulapu12345]

hmmmm voltage intensifier good job ...very nice

[radumotisan]

thanks. I should post a video showing how to actually make one of these. it's so easy!

[BLDBLITZ]

what in tarnation is this? use? purpose?

[radumotisan]

that's a capacitor, a device that stores electricity and can be discharged in an instant.

notice the increase in discharge intensity after the capacitor is added to the High Voltage power supply.

[Blodslav]

@BLDBLITZ A high voltage power supply. Steps up the voltage from a low voltage DC source. Use: from burning holes through paper to lighting barbecues to powering a crt display. Simple and easy to build, also very practical, for high voltage experiments to powering energy weapons (railguns and lasers)

[hobithole]

Thats amazing
