Heres an update on what I have been doing .

I have been working  on a wide bandwitdth filter to remove the switching noise of the switch capacitor filter .

The goal here is not to have a bunch of filter ranges but to have only one , That is why i opted for An 8th order active bessel .  I tried many orders of different kinds and this  work nice . There will be 3 of these identical filters . Also, I am using the 74hc series now for  ultra fast settling and better noise immmunity .

The range of this filter will be from 300 to 20,000 hz .

@ 300 hz the switching component is reduced by lots but still slightly visible , @ 400 its 95% gone , 500 and up its pure sine low low THD . There will be some hand selecting of components here because we are talking less than 1% , E192 resistors from digikey and some hand chosen caps from the electronics store . Asymetry will cause phase distortion and not a pure 120 , perhaps 121,119,120 etc ...

So now that I am even more satisfied with the THD level I am hitting on the pre-amp and amp stage , wich will be much less painful with a good sine . It was a bumpy ride last time because of all the noise induced by my breadboard , and I couldnt even test it on my pcb .

The LMC555 had some duty % stability problems near the higher frequency end it was more like 58/42 wich causes jittery settling time when you change the freq ,I am now using now a new super low drift super high symetry 50/50 duty state of the art oscillator from linear , 50/50 is very important here , the highest we will go is 2.5mhz so I expect the linear IC to be very solid even tho tho I didnt try it yet . 300hz from 20000hz will be selected by 2 x 1M ohm pots ,  the cap is internal to the IC  . For some very fast sweeping . Will make things significantly easier for a PLL add-on .

http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1096,P2186 (sot-23 grrr , hate these but I have no choice )

I anticipate this to be EXPENSIVE for those that still wanna purchase one from me , I dont expect much volume here @ all , this is the driver that I will be using for my research .Due to the long man-hours involved here for just making one of these , Istill dont know what I will do with this , perhaps a pcb run that people can buy , obviously before that is done I will have to contact a legal expert and see how I can protect my work from copycats , it will depend on what I can do to somebody who tries to sell my work , I dont want no hydrogen garage con-artists to be undercutting my work . Since I dont have a super-computer that can simulate this beast or a 5000$ licensed simulator with all the exotic parts that you can simply upload , everything had to be ordered from digikey and tested by me here on my breadboard (ouch) . And I tried ALOT of stuff  :'( (ouch$).

I have removed the overly complex phase shift oscillator from my pcb due to space limitations and its overall uselessness . I will post it here once I get myself to draw this biitch . My harmonics oscillator will be there tho , for those that are too lazy to make one yourselves . I already posted the schem on this site ... I removed everything that belonged to electrojolt on my pcb , but an add-on will be possible for those who wish to use it with my auto-gate and pulse protection .

Ok updates .

The circuit will only include preamp stage .

Meaning that there will be 3x 300 mA buffer driver for the push-pull npn pnp . I am certainly not gonna include 12 x fist sized heatsinks and components for the 2 x 3 phase sybchro alternators specified in the patent . Its all alot of work but deffinitly worth it . 50% maximum theoretical losses of what the load consumes . No 1000 watt motor with losses and speed limitations , not to mention portable and easily controllable speeds . For a motor you need advanced 5000$ pwm systems or a manual VARIAC lol or even a magnetic break .

Unfortunately I cannot find a good enough rail to rail +24-24 buffer so the amplitude will be a maximum of +12 and -12 . Rail to rail means thatyou can go almost +12 and almost -12 . So you use all the battery voltage you got .

Still shopping tho , I want this to have a possibility to drive a cell straight up with no transformer besides an 1:1 isolation transformer for better impedance isolation .

Ok well , Its gonna be ab with some biasing , wich sucks , means 20% more wasted watts .


I would of liked a super feedback class b yet ab , Ill try it and see if it works anyways .

6 of these will have to be constructed , 6 big *  heatsinks with 12x transistors . Shouldnt cost more than 70$ lol

1 per phase , 6 phases in all . I mean 3 phases x 2 .

Anyways this thing is gonna be just a joy to work with if everything turns out right .

Cant wait till spring break and experiment Meyers style .

Im gonna be really really busy at school this semester .

This thing can be used as an hvdc power supply as well , always wanted one of those , but the main oscilator will have to be changed for a goodl old cd4047 and the filter will have to be tuned , because the linear oscillator cant go low frequencies .

For those who wanna do this I will tell you how , just change a few resistors and caps and solder a ghetto rigged oscillator.

Yes , this is the final version , after  100's of  hours of grueling work . On this board lies perfection . On this board lies the future of HHO research . I will bankrupt Hydrogen garage once and for all . in case it wasnt already bankrupt .

A harmonics oscillator with gate synched EEC  , with 2 mosfet and room for 2 x 30 watt heatsink

A 200-25000 hz dual 3 phase oscillator pure sine oscillator  , pre-amp includes 6 x amps 50 p-p volts 300ma each with room for 6 x 20 watt smt heatsinks . pnp npn /w heatsink not included .

A 4 quadrant synched amplitude modulator with independant carrier and modulation amplitude and frequency , Puharich style . Uses a single driver as mentionned above .

Tell me if you see any mistakes haha !

A mistake means wasted bucks , this aint so cheap and small board like Jolt . Frikkin 3 minimum ...

The op amps wont get here till at least a month anyways .

Every new scan costs the exact same , even if you just added a single drill hole . This is how they make their money .

This is fine - you could use simply - an IR2133 - 3phase chip - to do this - and then you need a big toroid - with three separate transformer windings - each driven by an output from a phase of the IR2133 chip...
You also need to make sure that the "charging chokes" are exactly wound to match your cell...(one VIC circuit per tube set)-and that the "alternator winding" - secondary of the toroid windings... matches the whole VIC circuit - because when the cell and charging chokes and winding - go into parallel resonance - that the secondary winding does not interfere with the parallel resonance....(read between the lines patent 4936961). Also select the blocking diode very carefully - so that secondary breakdown point occurs at the right voltage - allowing - proper - parallel resonance to occur - for at least the last 3rd to 5th pulse of the oscillator...hmmm.. This allows you to get proper extremely high voltages on the cell - before and after the oscillator stops - step charging the cell...
