Title: Schematic self run system.
Post by: Romero on March 14, 2012, 05:47:35 PM
Recently I found on ou.com a tread where Magluvin posted one schematic with a self run device. http://www.overunity.com/12147/this-might-blow-your-mind/
Below is the schematic I believe will be easier to use.

I think this is the correct schematic:

Thank you Hitman, are you going to test it?
I have made the coil, now I need some time, maybe this weekend.

Yes I made the coil yesterday but I don't have a neo sphear magnet so I'm testing on a very well balanced bedini rotor, I've got it spinning with only 1.2volts but no self run :(   I'm going to order one of those magnets.

if you have a Diametrically Magnetised Magnet you can do it even better, the ball will be hard to get it aligned... look at the picture I posted before.

Any ideas on how to hold in place a DMM (Diametrically Magnetised Magnet) with the least possible friction.
We would need a type of spinning top with magnets, like in your pic, reminds me of that small self running motor that Mark built and was claimed fake.

Cheers Hitman

PS: I've already scraped 5 reed switches, I really hate reeds......

you need a dmm with a hole in the middle http://www.first4magnets.com/f679---20mm-dia-x-20mm-thick-diametrically-magnetised-n42-neodymium-magnet-x1-d10o-133-p.asp
add some plastic rod thru the centre and make it sharp one end... should be easy enough.
I have exact that type of magnet and I will try it soon.

Hi Hitman,

Hi CC,
Actually I'm not sure it can self run or if it ever will, I just try and most of the time fail.
The hall circuit needs power to switch the transistor on and off and only that switching is being used on the coil. You could maybe just add a gen coil to power your circuit but lets not run b4 we walk :)

What voltage would you want for a self runner at your gen coil if your input voltage is 6 volts.

Thanks Hitman

Thank you Romero, I finished the circuit and is all working fine, now I need to see how long will last the power in the battery.
I started from 1.201v and it dropped to 1.198v but now is back to the 1.201v
Running from a supercapacitor does not work for me.

Hi Romero,

If you put an ampmeter on 1.5, what would you expect amp draw to be?

I put my circuit together and it is drawing near 200mA.

Think I did something wrong !

Thanks, Garry

P.s. I do get between 4 to 5v pulses at approx 5us

in my case amp draw is 48-50ma. Just for curiosity add another turn on the primary...
What are the dimensions of the ferrite?

toroid is 25mm od 15 id and 9 deep

plugged in a small ferrite module - probably out of pc psu
much better result.

Post by: Romero on June 16, 2012, 01:10:37 PM
@garrym
Is this the first circuit you replicated? very easy to step to the second one where I had better results.
I don't like the waveform you have, try to move the windings around the toroid.
Are you connecting the probe at the toroid output?
Don't leave the multimeter probes connected for a long time, hours, days... it will draw energy, just test it every now and then then remove it.
Don't expect to get lots of power here, nothing more that the led's bridge.

Romero

Hi Romero,

Yes, I replicated first circuit.

Will now move up to second one.

Much better results using mini transformers from  old PSUs.

I have just replaced C1 with 2.5v 55f Super cap - 4 leds reasonably bright and
stable voltage at 1.237. approx 80mA draw but stable!

Scope was across gnd and collector of bd 139

Hi Romero,

My circuit is still running after almost 6 days, voltage now is 1.200v but I had it down to 1.103v then it recovered back.
I am using a rechargable battery with a supercapacitor in parallel.
I am going to test the second circuit you posted, I will keep you updated.

Post by: Romero on June 19, 2012, 04:32:40 PM
@crazycut06

Good to hear its working for you. Value of the resistor can be changed too or add a variable resistor in series with the existing one. Leave it running for a long time, even if you see voltage going down, don't touch, just wait. If its properly done should charge the battery.
If working ok then do the second schematic, it works even better.

Hello Romero and everyone. This is my first post but I've been trying to follow and read as much as my work permitted. I still have small version of your dynamo (unfinished), and never doubted it should work as claimed. My lack of understanding at that time as well as ability to make decent rotor at home sent this prototype from bench to the shelf.
Anyway, this isn't right thread for intro.
I tried to play last night with first circuit and different inductors/wires. Every combination was producing different waveforms. At first, I could only get two led's to light. I have 0.47F supercap in parallel with 1.5V battery and I had it running over 3 min. on the cap only. I need to find smaller (pF) capacitor. Serial inductor is wound on ferrite rod. I can't find any BD's and used 2N2905/2N2222 instead. Will continue to tweak more and try the second circuit.

Thanks

Title: Re: Schematic self run system.
Post by: Romero on June 29, 2012, 12:45:47 AM
@blackchisel97
try adding a second toroid as in my second setup with a capacitor and ground, that is going to work much better.
something strange with the supercap, I have 2 different makes 20F but only one keeps the charge. Having a battery connected worked all the time.You can also add a 1k resistor in series with the plus terminal comming from the bridge back to the battery, that will help to balance the system. A variable resistor will be even better, at least to find the right value then replace it with a normal resistor.
I will change and post an updated schematic based on my recent reperiments.

Title: Re: Schematic self run system.
Post by: blackchisel97 on June 29, 2012, 02:21:20 AM
Thanks Romero, will try that. You know, this is funny, I had 47k in series just as per your updated diagram. Some supercaps leak. My 0.47F are not great either but were cheap.
I just replaced small cap to 44pF (2x22pF). What bothers me is low A draw. Last night I was running on 2.78mA, now I read about 8.5mA. I tried couple dozen of different toroids and small ferrite core transformers last night looking for best results. Very interesting circuit.

Post by: Hitman on June 29, 2012, 04:10:20 AM
I also put together the first circuit exactly as the schematic and got it running on the first try :)
Its currently drawing 60ma but thats with no tuning what so ever, I'll leave it run down and see how long it lasts then I'll tune it and check again.

Cheers Hitman

Update: I added a variable resistor before I called it a night and was able to adjust input amp draw to 4ma, then let it run all night. battery voltage was 1.21 at start and this morning was down to 1.07.
I will try the second schematic with updates today.
Title: Re: Schematic self run system.
Post by: blackchisel97 on June 30, 2012, 08:21:53 AM
Hello.  Since I want to further test my previous (still running and stable) I built updated version of first circuit from scratch. This time on 2955/3055. So far I only tested one toroid with 2T/12T 0.6mm wire. I tried different serial inductors but there is no major difference. I had to increase resistance to 100k + 100k pot. 1k pot is set in couple hundred Ohms range. No supercap, just 2200uF. Amp draw from 1.2V NiKad about 41.5mA. Wave looks similar to Hitman's and about 10.4Vp-p.
I have 90pF atm.  If I change to 330pF wave looks similar to "h". I'll leave it running overnight and try different inductor tomorrow as well as second version. I'm not to crazy about current waveform.

Hi Romero, @all,
I checked my current draw, it goes up when I connect the diode bridge, then I tried to decrease the turns on my secondary, the power output went down, only 3 LEDs lit,  but when I check current draw it decreased when connecting the br-diodes from 1.6ma to 1.5ma is it sufficient to self sustain?

Romero

@romero
The first and second pic is the amp draw without the bridge of diodes connected and the wave form it produces, pic's 3 and 4 is with the diodes connected. as you can see my amp draw increases :( but I haven't added another coil on the output yet, that might help.

Post by: Romero on July 01, 2012, 11:49:35 PM
@Hitman
I don't know what to say... I am not sure what is wrong there, the input draw must drop when the bridge is connected to the source.What about when you short the led bridge output terminals?
What is the voltage after the bridge? Try using a variable resistor in series with plus lead connecting the bridge with the battery.

Hi Romero @ All.
My very first circuit built 3 days ago is still running well and I have a small battery gain - 0.002V.
My second one, on 2955/3055 (updated 1st circuit) kept draining battery so I decided to redo it. This time on 2N3904/3906. It will run on 1mA with all LED's dimm but that's not what we're after.
When I connect the bridge to the battery (of the second one) there is a slight increase in mA draw (AC side of the bridge remains connected to the circuit and LED's are lit).
I don't want to "disturb" my first one since it is holding well
I'm still working on it.

Title: Re: Schematic self run system.
Post by: blackchisel97 on July 02, 2012, 07:07:05 PM
@Romero
Yes, I found each toroid even done same way, same wire length brings different results. Unfortunately, those which I have a few (all the same) from power cord filters aren't the best. Same with transistors and even LED's. I need to find variable cap so I don't have to switch them every time.
I've been trying to run from single kHz up to 100+ depending on components.

This nice 1st waveform you have posted before was with second circuit ( two toroids and ground) - am I correct?

Thank you Romero. I've been trying different inductors and transformers to replicate my first but couldn't get same results (yet). Also, my first one started to drop until only 2 LED's were on. I tried to compare inductance to see if it can be a factor responsible. I didn't solve this one yet. I tried the second schem. but I left it for now until I fully understand how to replicate the first one each time.
Meanwhile I was (still) playing with other circuit which should desulfate the very battery which powers it. It is simple 555 triggering gate of N-channel Fet with 2 coils in series. It can be used to charge another battery via diode off the drain or the diode can go parallel with 2 coils from drain to the positive rail. There is a capacitor between the neg. rail and connection between both inductors.
I can post details if anyone is interested and want to play with it. I also work on electric fence to protect my garden from visitors (racoons +). Again, I can share details (if anyone has similar problem) when I get this done.

Hi blackchisel97,
Are you using the same transistor Romero posted? I think it's best or try using different low power transistors, and also try different lengths of winds on secondary, mine I manage to get the amp draw to 1.19ma and it's holding well, it's almost 3weeks and the battery voltage did not drop still 1.25v, I'm working on the second circuit but no succes yet, about your circuit pls post them, and I'm more interested on the electric fence to protect my things from being stolen.  ;D

Post by: blackchisel97 on July 21, 2012, 06:10:56 AM
Hi guys. Crazycut06, your yellow toroid looks like the one from PSU. Very nice result you've got on such low mA. I don't have the same transistors Romeo used. I tried 2N3904/06 instead and 2N222/2N2905 but I only had two of 2905 and used one already in solar levitating Mendocino motor.
My first setup was done on them and works better than others but it started to drop after a week.
I used same type toroid as you have.
Here is the site with electric fence schematics - http://www.pocketmagic.net/?p=2217 (http://www.pocketmagic.net/?p=2217).
I changed caps from IC pin 5 from 10n to 100n and in the last moment replaced 3055 with N channel FET. I had everything soldered on proto PCB board and just left 2N2222 as per schem. This could be simplified but works perfect and I'm getting over 1/2 inch spark (very painful :o). I don't see a reason for 20 Ohm resistor to be at 2W as everything runs cold even at max frequency. I used 12V ignition coil without internal resistor.
Second circuit I was playing with is from this site - http://bedinimotors.blogspot.ca/2010/06/bedini-ssg-circuit.html (http://bedinimotors.blogspot.ca/2010/06/bedini-ssg-circuit.html)  - scroll down the page. One thing puzzles me is that the core of those coils is drawn like two separate coils, not bifilar. I tried both with different cores and wire thickness and I didn't figure out this one yet. I know, this is nothing impressive but I don't have a budget to do what I wish and cannot sit and do nothing at all. Sort of therapy ;D

Hi Crazy,

Great setup!

Care to provide some detail on your circuit and most importantly, the coil/toroid ?

Garry

Toroid is from comp. psu 18mm outer, 10mm inner diameter wire gauge is .65mm (AWG 22). adjust for lower amp draw, when i check my setup's current draw, sometimes it consumes 1.19ma sometimes when i check again it consumes .68 - .71 ma, don't know why? or maybe there's a loose connection on the breadboard...    ;D

Happy Experimenting!  ;D

Title: Re: New schematics circuit for experimentation
Post by: aaron5120 on October 21, 2012, 06:20:53 PM
Hey, gentlemen and friends,
Since there has not been any active interchange of information here in this thread lately, I am posting a new schematics, a circuit designed by user ION from the OU forum, in order to stir up a bit the pot.
Remarks for the circuit:
This is not a blocking oscillator, rather it is a capacitor discharge SCR oscillator, but it is a looped circuit. I make no claims of a self runner, but the circuit can be used to experiment along those lines e.g. exotic core or dielectric materials might be used for the inductors or capacitors.
Note that an automotive lamp is used as a protection device should you get into a latchup condition by overdriving Q1 SCR. R1 adjusts the firing rate of Q1.
The recycling component SCR Q2 can be triggered at any voltage above the DIAC firing plus battery voltage by adding a voltage divider to the pot R4. Commercial DIACS such as those used in light dimmers fire from 28 to 32 volts. I forgot to add a switch between the battery. It is important to disconnect / reconnect the circuit should latchup of Q1 occur. Best to keep R1 at minimum and slowly increase until the circuit breaks into oscillation.
Some values are subject to experimentation based on your desired frequency of operation.
Happy experimentation then!

Hi everyone,
This is another simple but interesting circuit just for your experimentation:
Please see attachment.
The circuit from user janost of energeticforum make use of circulating currents. These currents between L and C are Q-times higher than the input to the circuit.
Normally in a LC-circuit, this shows a high impedance as a load and you can't get this current out for real work.
But in this case,  the L in the circuit is also the primary winding of a transformer, so the circulation current also gets induced in the secondary.
Loading the secondary lowers the Q factor in the LC-circuit,  but as long as it is oscillating,  the current draw is extremely low.

The GDT only fires when the oscillation is about to die out and as the resonant oscillations are always in phase with the grid,  it fires when the voltage difference is more than 200v, adding a kick to keep the circuit going.

From the viewpoint of the grid, the circuit looks like a load with a very high impedance.
The resonance is the source which is powering the bulb.
You may change the bulb to be an electric resistive heater.

May I know which was the question please? The schematics offered seems to be a peak potential switching circuit by the SCR to the second HV winding.
So does this concern with the coil shorting circuit?

Post by: Romero on February 01, 2013, 11:21:18 AM
@aaron5120
the schematic can be used with coil shorting, charging the capacitor then damp it to a load or back to the battery.
this circuit can be used in many other experiments, one of them can be a joule thief as the source of the power....

@aaron5120,
I was asking Romero on how to extract more amps from a coil.
if you have no coil shorting in place then you need min 30v at low amp but with coil shorting you can use the circuit even with 1 volt.
better test circuit in a solid state version before working in a magnet/coil...

Post by: aaron5120 on February 03, 2013, 12:25:41 PM
Thanks Romero, the circuit just came in handy. I was just going to experiment with a MOSFET JT circuit. This idea can improve what the SIDAC is going to shoot out from the joule energy accumulated in the secondary cap of the  FET JT circuit.
I was also planning to try the JT circuit with a sleeve loop ferrite coil, too. See this link:

Hi Romero

Regarding the toroid - are any of the windings on top of each other or are they all placed next to one another as I move around the toroid?

Thanks

that is not a self runner, its impossible to have it working considering how AC works and the link between the two axes is done via a rubber band. the two motors should be in sync and that will not work using a rubber... must be a chain connection or gears. there are multiple cuts in the video.

Post by: kEhYo77 on July 10, 2013, 03:24:58 PM
I agree with you on this, Romero. There must be some trickery involved. The rotors in those motors do not even have magnets to make any induction possible as a generator, am I right?
Title: Re: Schematic self run system.
Post by: Hitman on July 10, 2013, 03:48:52 PM
Yes everyone is right that it is impossible for it to work but how is he doing it then.
I did figure out 1 way to do what he's doing but with a large amount of modifications to 1 of the motors, cutting away the laminations inside the coil and replace with battery and circuit, you would also have to drill holes into the rotor and install magnets.

I would debunk this but it's just too much work and I won't waste my time on it unless someone else replicates it which I'm sure won't happen any time soon.

those rotors are made of aluminium with iron bits to work on induction. No magnets on them. There are 2 shorted coils on each stator.

Hi Romero

I finally got back to this device.
It's all wired up but it won't oscillate. 
No Freq showing up on the transformers or any place in the circuit.
I get voltage readings on the different legs of the transistors.
What causes the osc?  the 50pF cap between the transistors?
What is a good starting point for the 80k+47k POT resistors?
Any help would be appreciated.

DonL
Title: Re: Schematic self run system.
Post by: Romero on September 14, 2013, 01:26:20 PM
@dllabarre
50pf is very important but not critical, any capacitor from 30-100pf will work.
Try a toroid recovered from PC PSU, yellow... 2-3 turns on primary.
Check the basic schematic below without the 47k resistor and at the output connect scope terminals or led.
Are the transistors ok? Must work. Once its started then you will need to play with the output (wire turns, capacitor values) , to match the required power needed by the system to keep the battery charged. More voltage going back to the battery will affect the resonance. make sure the frequency remains about the same with or without load or loop back.

Thanks for the suggestions.

I used little orange toroids from a backup power supply.  I'll try to get some yellow ones from a PC PSU.
I bought 10 each of the same transistors in the schematic. I changed them in case one set was damaged.
I'll change back to match the simple schematic you posted.

Dear Hitman, right here is one of the "secrets". P (POT) Ferrite Cores are types of specially shaped ferrite transformer, ferrite with properties and special features. This core has a shielding effect, preventing and reducing electromagnetic radiation interference.
See more information here
http://ferrite.ru/en/products_en/epcos_en/pot_en/

But while we can talk about ferroresonance. See principle of generator Pantiuhov
