I have got one of the three patent missing. Patent No. 30378 is the generator developed in 1902 by Clemente Figuera. Later he developed a new generator in 1908 , the one we are replicating till now. The patent 30378 wasn´t unavailable until now since it was deteriorated and the patent clerk´s didn´t want to scan it to avoid breaking it. Today I have been to the Patent Office Archive and I have got some pictures of this patent (redable)
I will start to traslate it. By now I give you in advance that the design is different but is based in the same principle. The exciting current used in this case is alternating in sign or pulsed. And as woopy has discovered, it is clearly stated that the separation between the coil must be minimun
Also I want to deliver this patent in a few days to give time to people to replicate the one from 1908 and avoid mising them.
One interesting data: the patent from 1908 (filed the 30th of october 1908) was filed few days before the death of Clemente Figuera. I suppose that he was ill and decided to write his last patent. If so, he was not trying to earn any money from this last patent. It may be his heritage to the world.
Keep up the good work

Overunity of rotating Generator and the Lenz's effect
I just wanted to generalize the power gains for devices such as the generators with spinning rotors.
The overunity principle that applies to the Figuera's device is also the same for rotating generators. The Lenz's law is what makes the opposing torque to increase when a load current circulates in the stator. If the iron of the stator is designed to divert part of the induced magnetic field of the stator windings, the torque can be considerably smaller, that is, less mechanical energy is required to produce a given electrical power.
Think about it!

Clemente Figueras Generador Arduino Driver
Alrightythen...
I have found a simple way to do the coil driving with Arduino!
All you need is:
1. ONE 10k/100k Ohm potentiometer. Connect the middle leg to Arduino's "A0" analog input. The other two legs of the pot goes to +5V and GND on Arduino.
2. TWO Logic Level MOSFET transistors to do the switching (Logic level - like in IRL series - means that a mosfet is in a conduction saturation state at just +5V put to its gate). Connect the Gate of one mosfet to "Pin 3" and the others' gate to "Pin 11". Sources go to the "GND" of the Arduino board.
3. Connect +(positive) from a battery to both "North" & "South" coils and their ends to both drains in the two mosfets and -(negative) to the Arduino's "GND" close to the Source legs of mosfets.
4. Connect fast shottky diodes across each coil to do the freewheeling of current.
Program description:
Arduino is generating a digital signal at 32 kHz frequency using 2 PWM outputs. The value for each "sample" is taken from the sine table. There are 256 values of resolution for the "shape" of the sine wave and 256 values of amplitude. You can change phase shift by changing "offset" variable. Potentiometer allows to set the analog frequency from 0 to 1023 Hz at 1 Hz resolution...
NOW copy the code below to Arduino IDE window and save it to the microconroller and HERE YOU GO!

Hi Kehyo
Just tried your code, thank's for sharing
I wanted to see the difference with my set up, so i did not use the Mosfet but keep my Tip 41 c transistor with the 330 ohm base resistor.
So i get the 2 primaries firing at the same time, no shifting, and the offset should be 180 degree (as i read in the code that the 127 = 180 degree offset.??) Any idea of the other offset number to modify the offset ?
But very interesting the current draw fall down from 47 ma with 2 LED connected, to 24 ma, and the LED are something less bright but they are there.
Than i tried to reverse one of the primary on his core, and was almost sure that this should kill the magnetic field and the LED would quit, So there is almost no change in the brightness of the LED, the current draw is slightly less (about 22 ma) and on the scope one of the primary's trace is very weak and the other remain normal
Than i tried to modulate the frequency with the potentiometer (the actual frequency is about 28 Hz) , but nothig happen and i could simply put away the pot and no change on the system.
So not sure that the pot instruction is correct.??
@Guyla
Thank's for answering, very helpfull to make up my magneticpathbeginner mind.
@Wonju
Hope i do not disturb too much here, but i report my testing, hoping that we can find a way to transperce the Figuera secret.
OK hope this helps
Good luck at all

Hi Woopy.
127 is a value/a half of the length of the 256 long sine table, looks like it's correct but there might be an error in bit setting of the timer.. hmm..
About the pot: is it connected to the "A0"? can you read the changing voltage measured at this pin while turning the pot?
I'll check the code after work and will correct it, sorry for thatLast edited by kEhYo77; 11-16-2012, 01:32 PM.“ THE PERSON WHO SAYS IT CANNOT BE DONE SHOULD NOT INTERRUPT THE PERSON DOING IT ! ”

"The machine comprise a fixed inductor circuit, consisting of several electromagnets with sweet iron cores exercising induction in the induced circuit, also fixed and immobile, several reels or turns, properly placed. As neither of the two circuits spin, there is no need to make them round, nor leave any space between one and the other. "
So i am now testing some experiment with the 2 C cores totally magnetically connected.(no gap at all ), and the secondary core is simply approached or lightly touching (not between ) the 2 joined primaries C cores.

Hi Woopy,
I have seen your video No. 3 and you don´t have left any gap between the cores, but coils are quite far . I think Mr. Figuera is telling in the patent that the small gap is between the coils, not the cores. For that reason I suggest to test: coil + insulator + COIL + insulator + coil , where COIL could be oriented to search for the proper orientation ( also from the patent: “ the induced circuit properly placed …”
Is anyone testing the original Figuera´s design with the cores not longer than the coils? I hope to test it when I receive the components I need
Regards

Design Hint!!!
The correct separation distance between the iron cores is the minimum gap distance for which the ghost image does not manifest. That is, there should be no cross-talking between the primaries. You also do not want this distance to be larger because it will negatively affect the intensity of the magnetic field reaching the secondary. My previous advice was to start with a large air gap (about 1 cm) and bring them closer. Just before the ghost image appears. That is the reason why I built my device with adjusting channels.
The location of the coils within the column of the iron cores is not important. You can validate my statement through testing!
Woopy,
It is ok to play with the device to test its capabilities. I just do not agree to do it before we get the true replication of Mr. Figuera's apparatus. To me, it is worthless.

Hi Kehyo
I wanted to test some different offset number and for that i reloaded the code but this time at Overunity forum .
And to be sure i retested before modifying the code and this time the pot is working and i can see a lot of spikes very narrow and very strong (flyback spikes ) during the upper going and than the trace stays in a certain arc without spikes and than goes down also with a multitude of very strong flyback spikes. Very difficult to stay steady ( perhaps i have to go on mosfet) ??
Did you test youself the code and get a better result ?.
no more time this evening for experimenting.
Hi Hanon
thank's for explanation
Hi Wonju
Yes you are right , perhaps we should absolutely stay in your descriptive design as per your excellent drawings, but as you can see in my very first video, i was very near from the original Figuera with gap and rotating commutator, and got no significant results. I mean for me a real increasing of the output power on the secondary. I am probably making something wrong?
So perhaps we should open an other thread for the "discident " experimenters, and report here only the result relative to your drawing in the first page?
OK will go on the experiment and report
good luck at all

Woopy, try the new code now and put a scope on the output, please. Frequency setting and a correct phase shift is working as of now, I'm running it on test LEDs. Tomorrow the real thing...“ THE PERSON WHO SAYS IT CANNOT BE DONE SHOULD NOT INTERRUPT THE PERSON DOING IT ! ”

What I meant was to do it as Mr. Figuera's description. This is a very simple apparatus and we should be capable of replicating it.
As for the design hint, I am not sure if the minimum gap distance is the same, either when the secondary is open or when it is loaded. When there is an induced magnetic field due to a load connected to the secondary coil, the distribution of the magnetic field in the iron cores is different. The question should be, is the minimum gap distance the one determined with or without load? I do not have an answer to that question, but for sure, we will get it when testing the device.

Solid state alternator??
Question?? After reading the poor translation of the patent all I get is that this is as much of a solid state alternator as you could come up with for that time (which was ingenious by the way) without the heavy rotor and mechanical/electro-mechanical drag associated with driving one. Cant you just use a regular hollow transformer core, cut out a section, and put the section back with spacers for the secondary??

I am finished with coil setup and debating witch way to proceed with trigger mechanism. I have Audrino and unfortunately little experience in setting it up till now. I like your Audrino approach and would like to try it. I loaded the code with no problem, unfortunately need more clear schematics regarding setup and pin out. Please if possible include it in your forthcoming setup explanation. For a moment all I can report is that when doing manual connections on resistor as per Figuera instruction at position #1 primary coil #1 indicates perfect insulation from the primary #2 and center secondary receives induction. This is visible with the load as light is connected. Same happens in position #8 on opposite end as manually and momentarily I touch resistor, light is lit just as same. If I use my magnet pole sensor I can clearly see only one coil is activated at the time in steady connection. I noticed speed of transition on resistor is important because faster I transfer les amperage is needed. Personally I think this is going to work, the swing is there, induction is there, load lights up, it is all there. On shorting center secondary I see no reflection on primary which is beautiful. All I need is smooth switcher and it is running.
Hope is eternal.
