I got laid off due to hostile merger

verpies, I am sorry to hear that.
I hope you will manage to find a new job soon.
With your vast knowledge that should not really be a problem i am sure.

Thanks Hoppy, Magpwr and d3X0r for your comments/suggestions on the MOSFET.

Regards Itsu.

hi itsu and everyone,

As promised i have used my favourite 47N60C3 mosfet rated 600volts to replicate/modify the Mazzilli Osc circuit.
I have just uploaded the video to proof that it works-http://www.youtube.com/watch?v=vsJQ84DhODk

Good news for everyone even though the current drain on battery is around 2.4Amps with spark and around 1.2Amps for no spark(wider gap).
The best thing i noted for this Mazilli circuit , not a single component suffered from "any form of heating at all" even after running for 1min at high Amp draw.

I used 1Kohms 1/4 watt for resistor instead of 470ohms 3watt ,Zener i used 4.8volts 1/4 watt and i believe it will work even at 5.6volts as well.Please don't attempt higher values as i have no time to try other value since this is my 1st attempt testing only.The 2 x 10Kohms can leave it as it is as shown in video circuit or use 2x 1MOhms work same as well.For high voltage diode instead of using 1N4007 i used available component 1N4937 rated at 600VOLTS.
For inductor to save time i used 220uH i think rated at 1Amp maybe instead of winding on toroid using 18AWG magnet wire.

The most important component the capacitor i think might be the culprit 680nf 250volts.I was using  470nf 400volts spark worked fine as shown in video but upon adding A/C caps 220nf rated 250volts the current suddenly increases to around 3.5Amp with no spark.I have no time to try with lower value capacitor which may or may not optimize spark length.   

This is a cool HV circuit with no heating detected even after 1min runtime.

running higher voltage my zener's do get hot after a while... but adjusting the voltage divider resistors for the desired run voltage should help that.

With respect, the use of 4.8V zener diodes to protect the mosfet gates is not sensible as the gate voltage needs to be in the region of 11V to 18V to fully switch-on the mosfet. A zener rated at 5W with a 470R non-inductive resistor should prevent damage to the gate. From my experience, a 1 Watt or lower rated zener can easily rupture, resulting in damaged mosfets, so play safe and go for a 5W rating. Not fitting zener protection is akin to 'flying on the seat of your pants'. Nick take note because I did not see them on the photo you posted some time back. With good gate protection, most mosfets should work that have at least a 200V VGS rating and adequate current rating. Don't increase the value of the gate resistors as this is not necessary and just degrades switching performance at high frequencies.

hi hoppy,

If you take a look at the mosfet datasheet the voltage needed to turn on the gate is 2volt to 4volts.I have proven this via my previous video 1watt HHO ver 1.0 using only around 4volts supply to power this same mosfet to split water.
1Kohms resistor is needed to limit current to mosfet and zener diode 4v8 at the same time for this HV circuit.It's pointless and costly to use higher power rated passive component in this case.
If there is no heat detected on any component including the fragile 1/4 watt zener while in operation it is not an issue related to current overload at all.
