Here is a picture of this circuit from the video.

Thanks key for posting that image.

Kone, I have marked the caps on the picture. Yellow AC cap seems to be in parallel just like the schematic. (I put a 100µF,35V DC cap here in my circuit. Think that's wrong.) But then he has this DC cap and I cannot see a diode.

The cap must work like a spring that is being compressed (filling up) when the magnet gets attracted and then releases its power in the opposite direction (empties in the other direction) thus pushing away the magnet. This is the principle Romero said was "easy" and shown in his speed under load video. With this principle it should be possible to achieve speed under load at any speed. For this to achive I believe we must have the circuit right.

The next thing is very imortant. Romero repeatedly stated that the two coils must work together and they should not fire a the same time. There must be a way that each of the two coils fill a cap without seeing a load. I think this is the reason why the coils must not fire at the same time.

This is one option of getting this to work. The other one, which is probably more difficult to achieve might involve mixing of frequencies just like kapanadze.


When my coils are singing this basically works like shorting many times but without a reed. I am getting many large spikes and can fill an output cap fast to double the input voltage (which coincidently is about the voltage my DC driver caps are). I think this is what Romero achieved back in the coil shorting thread just before he came up with the muller device.
I am at the point that I can drive the second coil from the first one at a higher voltage. But the pulse must not be too long or the voltage will drop. Now if I don't have the circuits right I might be missing something important. Romero said I was on the right track but could not go into details for his personal reasons which I respect.

Hi Chal


The diode is there, if you look closely, up from the dc cap and a bit to the right there is a wire reflection of that diode mounted vertically. That is why it is hard to see it from the top view.

Replicated and made it work.
My english is not so good so I will try to use the most simple words I can. These are the things I followed:

1. The original coils were made with  "Lytz" copper wire - which consists of multiple wires. I used 4 copper wires, 0.1mm from 4 individual bobbins. After finished the coil, the end of a wire goes to the beginning of the next wire (on the same coil) - like the tesla patent - until there are only two wires left (begin and end). This boosts the voltage sky-high.

2. The original rectifying diodes are not designed for high frequencies. Two choices:  either special switching diodes like in the PC switching power supplies... or vacuum tube rectifiers. RV12P2000 - my favourites. I suggest to all people that do experiments: as soon as you have a stable version of something - try to replicate using vacuum tubes (triodes) as active elements. That device would be imortal, as vacuum tubes can be made using any technology (even medieval technology)

3. Don't go to "small voltage, high amps" concept. Use "small amps, high voltage". tesla did this. There's a formula with heat depending of volts and amps.

Key, ok, good. How would the DC cap be connected then?

Hey skaarj, can you show a video of what you replicated? Thanks.
