I apritiate you have made such a simple HV generator, but for maximum you will have there 3250V. That amount of Voltage of high frequncy, i asume by its color that is around 40KHz, will not be able to kill you but shure can buzz your finger. Anyway Continue with good work, and be real with the video head lines. :)
This works unlike anything else you see here on UA-cam. It is a blocking oscillator. But there is a risk that the leakage inductance will kill the transistor.
From a sparks expert - nice video and nice project. If you are just playing with clickbait numbers then fine, but if you are interested in an accurate claim then a low-current spark that starts between sharp wire ends at about a millimeter air gap, and stretches out longer when started, would be probably less than 2000V.
i woulds say 30kv. If you Tweak the turns on primary/feedback a bit,, you can get way more voltage out. And make the transistor stay colder. Maybe im wrong, i blame the beer.. Nice video, keep it up. But a schematic is always nice
I made one with good ol' 2N3055 while back when I was a kid and added a voltage doubler with 68nF capacitors. And accidentally touched it. It was damn powerful and it hurt as much as hitting my hand with sledgehammer. I checked and it was drawing 150 watts.
That is an 8:500 ratio transformer. Should be able to take the 12vdc from the adapter and increase it to 750 volts. Correct? Calculating like this: (500windings in secondary / 8 windings in primary ) x 12vdc supply voltage = 750 volts? The 2A supply would be diminished by the same ratio or 2000mA/(500/8)=32mA. Anyway, looks like spark gap was about right for 750v. 30KV would jump a spark gap of about 1 cm so 300,000 volts should jump a spark gap of 10 cm. If you wanted to get 300,000 volts out of the 12vdc adapter and you used 8 windings on the primary then each winding would have 12 / 8 = 1.5 volts. 300,000 / 1.5 = 200,000 windings... so theoretically you would need 200,000 wingdings on the secondary side (not practical due to many factors). A spark gap is not the ionized air in an active arc as it becomes conductive when ionized. A spark gap in air is the un-ionized gap width.
correct...as soon as I saw the claim and the size of the spark gap I immediately thought......BULLSHIT !!!!! yeah...it's around 30Kv per centimeter or so....

@@nooceluap7760 yes, it has to be. In fact, every switched mode power supply rectifies the AC from your power socket, filters it though some capacitors and then there is the circuitry that switches the main transformer. The DC you feed into a transformer need to be pulsed and switched at very high frequency, at least if the transformer is small and have low induction. If the frequency isn't high enough, you saturate the transformer core and the voltage does no longer induce on the secondary coil. You can see that If you take a reasonably sized transformer and apply voltage to the primary, it does induce some voltage on the secondary for a brief moment. After that, the core will be saturated and the primary will act like a short circuit.

It's definitely not 300 kV, I think around 3000V. The arc can be stretched for some distance thanks to the quite high current, but only once it's been started. And if you see from the video, the arc begins only and very small distace.

You are right. Ignition coil is used to produce high voltage that goes to the spark plug. It is actually a step up transformer having plenty of turns in the secondary but finer wire than the primary.

F A K E ! 1) I order to create 300 kV from 6 v we need transformation ratio of 300000 : 6=50000, which means that if primary coil has 8 windings, secondary must have 8x50000=400000 but there are just 500. 2) with 300kV the spark sholud be 10 cm, in this case it is about 1 cm 3) with such high voltage there is no way secondary coil to be wound like that, and white wire to go over other windings. That would blow in second.

Good work sir, but I must say that. If that spark reach to 1 kV you're very optimist. Don't mind how far spark will become, but from what distance it will start, because in that moment voltage between electrodes break air resistance. After that spark will become bigger because it creates a sort of "road" of ionised and hot air that decrease air resistance and the spark distance can increase. If 1 cm of air necessitate of approximately 16 kV to be break from voltage, your less than 1 mm spark will have a voltage 10 times smaller. So approximately and for my opinion optimist 1000 Volt spark. Sorry for my very awful English knowledge. Good to see your video
1mm is approximately 1000v (this varies butt still) given that I believe there 10-20kV Moreover you could calculate this by dividing secodary winding turns by primary winding turns and multiplying this on half of the supply voltage. So basically reduce primary winding turns and improve your toy's performance)
Nice work! . Can you modify this into continuously operating oscillator to make a Negative iron generator below 15KV, with a reverse biased high voltage diode??
First off, he does not have 15kv here, maybe 10 at most. Second, yes you can rectify the output, one direction will produce a far higher voltage output than the other, keep the capacitor low (unless you want to die), connect to the ionizing needle through a high voltage high resistance resistor(to reduce the danger of shock), value of this resistor and the filter capacitor depends on design specifications.
If you think that 300000v you wrong! His wires wouldn't be able to handle that much voltage. They would melt in a instant. Also the arms ar TINY of this transformer.
You should know that every 1000 V the air resistance shoots at a distance of 1 mm at a humidity of 60%. You have 2000V here, plasma stretching is not an indicator, plasma is gas and I don't see a 300mm spark anywhere.

You need capacitors and diodes wired in series to get actual high voltage generating. This is part of the circuit but not the whole process.
If you want DC, true that. If you want to make fancy Tesla like things, you want AC voltages and these coils to operate at resonance.
