Re-Inventing The Wheel-Part1-Clemente_Figuera-THE INFINITE ENERGY MACHINE

[RandyFL]

Hi,

I just wanted to do a kind of brainstorming with the Figuera's device.
Bajac.

Hello Bajac,
I assume you are using both the arduino version and the 555 4017 s and 4081 version in your parallel work...whats holding you up... the amperage at the gap ( the BDX53c gives 8 amps - the 2n3055 gives a higher amperage ).......................Is it the iron...? iron with some carbon in it = steel.......steel with some silicon in it = electrical steel.....the iron that showed up at my house was round...and me like a clown had it squared and made 7 tiny transformers out of it....I should have left it round and had the ends squared and made two transformers....sheesh! Whats your views on the difference between a coil and a solenoid...

A solenoid is a type of electromagnet when the purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as inductors, electromagnets, transformers, and sensor coils.

Lastly are you prepared to do the math...
http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/indcur.html
I understand some of the mathematics...as I stated before the mathematics have to be spot on this side of the equation.......After " it's for free " who knows...

All the Best

Thanks for help! :-)

Arduino UNO R3
Other sketches do well

errors:
sketch_jun24a:17: error: 'prog_uchar' does not name a type
In file included from sketch_jun24a.ino:11:0:
sketch_jun24a.ino: In function 'void __vector_9()':
sketch_jun24a:133: error: 'sine256' was not declared in this scope
sketch_jun24a:134: error: 'sine256' was not declared in this scope
'prog_uchar' does not name a type

Seems to refer to this line:
                   PROGMEM  prog_uchar sine256[]  = {


---------------------------
The output is not expected to produce sine wave directly at Arduino pins. It is designed to act similarly to a SMPS.
The primaries will get a diode in parallel and they will integrate the variable PWM signals to a sine current. And while current is directly proportional to flux we will get a sine shaped flux.
So the question is regarding your setup: Do you see at scope the pulse width changing (OK) or are pulses stable (wrong)?

Ah... perhaps so. The only way I can reproduce the compile error messages you've got is to corrupt that line somehow. Even by commenting out the
#include "avr/pgmspace.h"
line my sketch still compiles without errors.

What version of the Arduino IDE are you using? I'm using version 1.0.2, and an Uno R3.

You could try putting

const prog_uchar sine256[] PROGMEM = {

instead, which seems to be another preferred syntax for the PROGMEM modifier:
http://www.arduino.cc/en/Reference/PROGMEM

I don't know what else to suggest at the moment. I don't think the issue is in the following parts of the array declaration; errors there produce a different complaint from the compiler.

The output is not expected to produce sine wave directly at Arduino pins. It is designed to act similarly to a SMPS.
The primaries will get a diode in parallel and they will integrate the variable PWM signals to a sine current. And while current is directly proportional to flux we will get a sine shaped flux.
So the question is regarding your setup: Do you see at scope the pulse width changing (OK) or are pulses stable (wrong)?

Yes, the pulse width changes smoothly between 0 and 100 percent,  at the frequency that is set by the potentiometer voltage on pin A0, varying from under 1 Hz to over 1 kHz. The phase of the two signals is controlled by the value of the "offset" variable, which in my sketch is also controlled by another potentiometer on pin A1 and an analogRead statement. In the scopeshot above, one channel's PW is increasing and the other is decreasing.

Thanks for help. I will try it ASAP. My installation IDE 1.6.5

Your report indicates: the sketch seems to work correctly at your setup. If you drive FETs with those signals and put at each inductance a diode in parallel (kathode to + / anode to FET) - then you have your Figuera drive perfect.

You should know that Figuera mechanic wave form generator did not generate sine but half sines: see my post #2248. It is a true simulation of the original circuit.
But with Arduino we can check all possible wave forms by changing the contents of the array.

To those people having problems with arduino, I highly recommend to first, copy the code from this forum and paste it into a Notepad application. Second, visually inspect the code to look for any suspicious character not present in the original program copied from the forum. If found, make the necessary corrections. And third, copy the program from the corrected Notepad version and finally paste it into the arduino environment.

In the past, I have gone mad because of errors showing up in arduino after copying and pasting the program. The problem is that different word processors have characters that are similar but they have different ASCII code. For example, I recall an issue with double quotation marks. After three weeks of craziness, I discovered that the symbols were slightly different. The one being copied had a small sloped profile, which has different ASCII code than the one used in the arduino environment.

The Notepad is a simpler application that does not have all the processing and special characters as other applications such as MS Word. Any strange character will show up in Notepad.
I hope the above can help you.

@Randy,

I am only using arduino. The transistors driving the coils are IGBTs rated 600V@20A.

My latest thoughts of the Figuera's apparatus tell me that my set up does not really follow the teachings of the patents. as I indicated before, the shape of my coil cores does not seem to be a match with the cores shown in the patent.

See attached document. When I first posted the paper, I visualized the cores as shown on page 3. This was my impression from the plan view shown on page 1. On page 4 I am showing the cores used in the device that I built. I used these cores because they were already available from an old transformer. HUGE MISTAKE!

I will redo the cores to look more like the ones shown on page 3 of the attached document. I am planning on using cores with a length of approximately 12 inches long with a cross-sectional area of about 2" x 2".
