The French circuit replication

@KEhYo07
Thanks for posting that link to the SIM. I didn't get a chance to work with it is because I went ahead and built the circuit. I had all the parts except the transformer so I used the 12v one that I had on Xee2's circuit. The circuit ran good. The Xee circuit is much simpler but I do really like this "French" circuit. Here is a video of it running:

@dragon
It does run a little too fast. I didn't scope it but when I listened to it with my little radio you could tell that it was higher than 60 hz. The only real problem that I had with the circuit was the IRF510 mosfets from radio shack didn't work. I tried some IRF730 that I had and they worked fine. . This setup looks like a very good "put it in a box and use it" situation.

@Xee2
Your extreme simple setup still looks like a major winner to me because almost anyone can gather the parts and have the whole thing running in one afternoon.

@Cherryman
Thanks for post the link to that French video. That was a real find with good information---even if I didn't understand a word of it. The pictures were good and told the whole story.

Xee2 OU video.

Here's the two for the price of one video: At around 1:00 minute into the video you can hear the faint ring in the back ground from the transformer. If you listen closely, It sounds like air leaking from a balloon. The second bulb runs for free through the full 1k range.

@ SkyWatcher
Your transformer seems good to me. The Radio Shack will not generate enough voltage to light a CFL. But, that should mean it is generating more current. However, it could also mean that it has a lot of losses in coil resistance. The only concern I would have would be that too much voltage may damage the circuits it the LED bulbs. But, LaserSaber must have more than 500 volts coming out of his toroid, so I think you will be safe. If you have two LED bulbs you might start with them in series so that each only gets half of the output voltage.

Hi folks, Hi xee2, thanks for the reply and information.
Ok, I checked the size dimensions of that transformer and mine is about an inch larger in dimensions all around and I have a little more space for my secondary using 30 gauge and mine is 54 ohms secondary, that means since yours is that much smaller, then it must have greater than 30 gauge wire on it for the 117 volt winding.
And the ohms for one half of my primary is 24 gauge, 1.7 ohms, so again since your transformer is smaller, it must have greater than 24 gauge wire for center tap wire halves.
And of course the turns ratio is around 10:1. Anyone happen to know what size wire is used for primary and secondary on that shack transformer.
Only thing is, my transformer will ignite a 15 watt cfl at 12 volt input, so it might have too many secondary turns for those led bulbs, may have to rewind and count turns.
peace love light

edit: ok, i just thought of hooking my secondary directly up to ac outlet and one half of primary showed 12.3 vac, so it looks like I'm pretty close to the proper turns ratio. It must be driving the cfl by flyback action, does your transformer fire up a cfl xee2, thanks.

[xee2]

Is it possible for you or anyone else who has that radio shack transformer to measure the ohms of the secondary and also each strand of the center tapped primaries

147 ohms for 120V coil and 1.5 ohms for each half of the 12V coil. Not much heat.

Thanks to Alex and Lasersaber what a success story lol

just an update

with 10 3 w 220v ac ld lamp(20 led- imside) it will not light up
with 10 3 w 220v ac led lamp (5 led) all lit up 150 lux @ 12v dc supply

Hi folks, Hi allen b., nice work, love to see your video and results.
Is it possible for you or anyone else who has that radio shack transformer to measure the ohms of the secondary and also each strand of the center tapped primaries to get an idea of the turns ratio between primary winds and secondary, thanks much.
This way way i can wire my own transformer, since i have many laying around here.
Unless anyone knows what the turns ratio is with these type transformers of 12 volt to 117 volt, thanks.
peace love light

edit: oh also, how is the heat in the transistor, is there much if any, thanks.

A Big Thumb's Up To All

Hello Everyone I've not posted in a long time.But had to tell Everyone ....Wow And a BIG THUMB'S UP..!!!
Thanks all Tec

Xee2's circuit.

I have some extremely exciting news! I show no increase in input amperage with the addition of the second 120 volt LED bulb at maximum illumination, while in reaonance. The ringing rises higher in tone, but the new amp meter needle stays peged at 500 milliamps when the second bulb is attached and glows to full brightness. I'm starting to make a video of it. Conclusive proof of overunity video! Time to pop the corks, this circuit's a blue ribbon winner!

And here is a simulation
FLIP FLOP SIM

@Xee2,

Is the base diode a Schottky type fast switching diode in the 914 series? Another question is; Does your transformer ring? I think the resistence value would have to change after adding a diode to the transistor base. A 1k pot or trimmer, like I'm using would allow one to alter the tank oscillation frequency to regain the former brightness. The diode prevents feedback interference from reaching and disturbing the base R C tank oscillation integrity. The transformer's either ringing or it's not. There's only one full brightness. I'm running 12 volts into a 3.3uf ceramic capacitor wired across the legs of a 1k variable resistor. The "Ring is the Thing"!

The diode is there to protect the circuit and improve efficiency, not increase brightnessl A low range variable pot in place of a fixed resistor, would permit tuneing to peak resonance to allow for a diode or additional bulbs.

Diode was 1N4007. The Radio Shack transformer does not make any noise at any frequency tested (30 Hz to 20 KHz). The base goes 10 volts negative but the transistor does not seem to be damaged (adding diode might add protection, but this does not seem to be needed). A pot is a good idea, but I never seem to have the right value handy. Purpose of tests was to get an ideal of brightness vs power consumption. The circuit was just an easy way to drive the 120 VAC bulb that worked.

Astable multivibrator----the flip flop basic circuit

Here is a link to the "Flip Flop" circuit:

The Flip Flop

This would be a fun circuit to run on a Spice computer simulator with the addition of the mosfets and the transformer and see what was going on. Unfortunately I don't have that simulator. I really think that we might adjust this circuit correctly and maybe outperform a Joule thief. This could be hooked up to Lasersaber's big metglas toroid and work just fine.

Just adding some info.

Hi guys, here is a kind of simular french version, including a tutorial.

Incroyables Expériences [73] Fabriquer un onduleur / Make an inverter (nouvelle) - YouTube

Here is circuit diagram from Youtube video.

P.S> It looks like traditional bipolar oscillator to me..

[xee2]

I rewired Xee2's transformer circuit, with a switchng diode from the 1k pot capacitor junction to the transistor base, this time a Motorola 13007. The luminosity increased ...

Interesting. When I added a diode in series with the base the light output decreased slightly. It is good to have multiple testers.
